Description

本発明は、家庭用の熱交換型換気扇やビルなどの全熱交換型換気装置に使用する積層構造の熱交換器に関するものである。   The present invention relates to a heat exchanger having a laminated structure used for a total heat exchange type ventilation device such as a heat exchange type ventilation fan or a building for home use.

従来、この種の熱交換器は、通風抵抗や熱交換効率などの基本的機能を向上しつつ製造コストを抑えるために、伝熱板とスペーサーとを接合せずに積層することによって熱交換器を形成したものもある（例えば、特許文献１参照）。   Conventionally, this type of heat exchanger is a heat exchanger by laminating heat transfer plates and spacers without joining them, in order to improve the basic functions such as ventilation resistance and heat exchange efficiency and to suppress the manufacturing cost. Some of them are formed (see, for example, Patent Document 1).

以下、その熱交換器について、図２０（ａ）、図２０（ｂ）、図２１を参照しながら説明する。   Hereinafter, the heat exchanger will be described with reference to FIGS. 20 (a), 20 (b), and 21.

図に示すように、合成樹脂よりなるスペーサー１０１は、伝熱板１０２間の間隔を保持する間隔リブ１０３と、間隔リブ１０３同士を連結する連結リブ１０４と、間隔リブ１０３および連結リブ１０４上に配置された小突起１０５と、上下に積層したスペーサーの相対する面に、互いに嵌合する凸部１０６と凹部１０７を一体成形することによって得られる。伝熱性と透湿性または伝熱性のみを有する伝熱板１０２は、位置合わせ用穴１０８を備えたものである。また、位置合わせ用穴１０８は、スペーサー１０１と伝熱板１０２を積層した際に小突起１０５と嵌合するものである。   As shown in the figure, the spacer 101 made of synthetic resin is provided on the interval rib 103 that holds the interval between the heat transfer plates 102, the connecting rib 104 that connects the interval ribs 103, and the interval rib 103 and the connecting rib 104. The protrusions 106 and the recesses 107 that are fitted to each other are obtained by integrally molding the small protrusions 105 arranged on the opposing surfaces of the vertically stacked spacers. The heat transfer plate 102 having only heat transfer and moisture permeability or heat transfer is provided with an alignment hole 108. The alignment hole 108 is to be fitted to the small protrusion 105 when the spacer 101 and the heat transfer plate 102 are laminated.

熱交換器１０９はスペーサー１０１を交互に９０度ずらしながら積層し、スペーサー１０１間に伝熱板１０２を介在させることによって得られる。また、熱交換器１０９はスペーサー１０１の四隅に設けた凸部１０６と凹部１０７が嵌合しながらスペーサー１０１同士を連結保持する。   The heat exchanger 109 is obtained by stacking the spacers 101 while being alternately shifted by 90 degrees and interposing the heat transfer plate 102 between the spacers 101. The heat exchanger 109 connects and holds the spacers 101 while the convex portions 106 and the concave portions 107 provided at the four corners of the spacer 101 are fitted.

上記構成において、一次気流Ａと二次気流Ｂを流通すると、伝熱板１０２を介して一次気流Ａと二次気流Ｂの間で熱交換する。
特許第３０２３５４６号公報 In the above configuration, when the primary airflow A and the secondary airflow B are circulated, heat exchange is performed between the primary airflow A and the secondary airflow B via the heat transfer plate 102.
Japanese Patent No. 3023546

このような従来の熱交換器１０９はスペーサー１０１と伝熱板１０２を接合せずに積層したものであるため、積層のずれに起因する密封性の低下による気流の漏れが増加するという課題があり、積層のずれに起因する密封性の低下による気流の漏れを防止することが要求されている。   Since such a conventional heat exchanger 109 is formed by laminating the spacer 101 and the heat transfer plate 102 without joining, there is a problem in that airflow leakage increases due to a decrease in sealing performance caused by misalignment of the lamination. Therefore, it is required to prevent airflow leakage due to a decrease in hermeticity due to stacking deviation.

また、熱交換器１０９は合成樹脂よりなるスペーサー１０１と伝熱板１０２の二つの部品を別々に用いて形成されるため、部品点数が多く、加工工程が多くなるため、製造コストが高くなるという課題があり、部品点数が少なく、加工工程を少なくすることによる製造コストを低減することが要求されている。   In addition, the heat exchanger 109 is formed by using two parts of the spacer 101 made of synthetic resin and the heat transfer plate 102 separately, so that the number of parts is increased and the number of processing steps is increased, which increases the manufacturing cost. There is a problem, and it is required to reduce the manufacturing cost by reducing the number of parts and processing steps.

また、熱交換器１０９はスペーサー１０１の四隅に設けた凸部１０６と凹部１０７が嵌合しながらスペーサー１０１同士を連結保持する構成であるが、スペーサー１０１を交互に９０度ずらしながら積層する工程に不備があり、スペーサー１０１を同じ方向に積層した場合、スペーサー１０１に有する凸部１０６と凹部１０７は連結保持することが目的であり、スペーサー１０１は誤った積層方向でも連結保持される。この場合、熱交換器１０９は伝熱板１０２毎に同じ方向に通風路が形成され、一次気流Ａと二次気流Ｂを熱交換器１０９に流通すると、誤って積層した部分については熱交換できない。このように、スペーサー１０１の積み間違いによって、伝熱板１０２毎に正しく通風路が形成できないことに起因する熱交換効率が低下するという課題があり、正しく通風路が形成できないことに起因する熱交換効率の低下を防止することが要求されている。   The heat exchanger 109 is configured to hold the spacers 101 while the convex portions 106 and the concave portions 107 provided at the four corners of the spacer 101 are fitted together. When the spacers 101 are stacked in the same direction, the purpose is to connect and hold the convex portions 106 and the concave portions 107 of the spacer 101, and the spacers 101 are connected and held even in the wrong stacking direction. In this case, if the heat exchanger 109 is formed with a ventilation path in the same direction for each heat transfer plate 102 and the primary airflow A and the secondary airflow B are circulated through the heat exchanger 109, heat exchange cannot be performed for the portions that are mistakenly stacked. . As described above, there is a problem that the heat exchange efficiency due to failure to correctly form the ventilation path for each heat transfer plate 102 due to erroneous stacking of the spacers 101 is reduced, and heat exchange due to the failure to correctly form the ventilation path. There is a demand to prevent a decrease in efficiency.

また、熱交換器１０９はスペーサー１０１を交互に同じ方向に積層し、誤った積層方向でも連結保持されるため、積み間違いなどの生産不良が起こり、量産性が低くなるという課題があり、単位素子の積み間違いを無くすことによる量産性を向上することが要求されている。   In addition, since the heat exchanger 109 alternately stacks the spacers 101 in the same direction and is connected and held even in the wrong stacking direction, there is a problem that a production failure such as a stacking error occurs and the mass productivity becomes low. There is a demand for improving mass productivity by eliminating mistakes.

本発明は、このような従来の課題を解決するものであり、量産性を向上することができ、また単位素子の積み間違いを無くすことによる量産性を向上することができ、また部品点数が少なく、加工工程を少なくすることによる量産性を向上することができ、また積層のずれを防止することによる量産性を向上することができ、また伝熱板の位置決めを容易に行うことによる量産性を向上することができ、また製造コストを低減することができ、また部品点数が少なく、加工工程を少なくすることによる製造コストを低減することができ、また設備投資を少なくすることによる製造コストを低減することができ、また気流の漏れを防止することができ、また単位素子の積み間違いに起因する密封性の低下による気流の漏れを防止することができ、また積層のずれに起因する密封性の低下による気流の漏れを防止することができ、また気密性の高い単位素子を形成することによる気流の漏れを防止することができ、また正しく通風路が形成できないことに起因する熱交換効率の低下を防止することができる熱交換器を提供することを目的としている。   The present invention solves such a conventional problem, can improve the mass productivity, can improve the mass productivity by eliminating stacking errors of unit elements, and has a small number of parts. , Mass productivity can be improved by reducing the number of processing steps, mass productivity can be improved by preventing misalignment of the stack, and mass productivity can be improved by easily positioning the heat transfer plate. It can be improved, the manufacturing cost can be reduced, the number of parts can be reduced, the manufacturing cost can be reduced by reducing the processing steps, and the manufacturing cost can be reduced by reducing the capital investment. Can also prevent airflow leakage, and can prevent airflow leakage due to poor sealing due to incorrect unit element stacking In addition, airflow leakage due to a decrease in sealing performance due to stacking deviation can be prevented, and airflow leakage due to the formation of highly airtight unit elements can be prevented, and a correct ventilation path can be formed. It aims at providing the heat exchanger which can prevent the fall of the heat exchange efficiency resulting from being impossible.

図４（ａ）、４（ｂ）、４（ｃ）に示すように、第一の遮蔽リブ７ａと第二の遮蔽リブ７ａａは単位素子２ａを交互に９０度回転しながら積層した時に、隣接する第一の遮蔽リブ７ａと第二の遮蔽リブ７ａａが重なり合うように形成され、熱交換器１ａの通風路５を流通する一次気流Ａおよび二次気流Ｂが熱交換器１ａの端面から気流が漏れないように遮蔽する働きと、伝熱板４を一定の間隔に保持する働きがある。   As shown in FIGS. 4 (a), 4 (b), and 4 (c), the first shielding rib 7a and the second shielding rib 7aa are adjacent to each other when the unit elements 2a are stacked while being alternately rotated by 90 degrees. The first shielding rib 7a and the second shielding rib 7aa are formed so as to overlap each other, and the primary airflow A and the secondary airflow B flowing through the ventilation path 5 of the heat exchanger 1a are generated from the end face of the heat exchanger 1a. There is a function of shielding so as not to leak and a function of holding the heat transfer plate 4 at a constant interval.

なお第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａは熱交換器１ａの伝熱板４を一定容積内で広く取るために、方形の単位素子２ａの両端部に形成する構成としたが、熱交換器の設計や量産性などにより適宜決定する。   In addition, although the 1st shielding rib 7a and the 2nd shielding rib 7aa were set as the structure formed in the both ends of the square unit element 2a in order to take the heat-transfer plate 4 of the heat exchanger 1a widely within a fixed volume, It is determined appropriately depending on the design and mass productivity of the heat exchanger.

図４（ａ）、４（ｂ）、４（ｃ）に示すように、遮蔽リブ凹部８と遮蔽リブ凸部１６は単位素子２ａを交互に９０度回転しながら正しく積層した時には、隣接する遮蔽リブ凹部８の凹部と遮蔽リブ凸部１６の凸部が嵌合するよう形成される。熱交換器１ａは第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａに設けた遮蔽リブ凹部８と遮蔽リブ凸部１６の嵌合により、単位素子２ａ同士が互いに固定化され、且つ単位素子２ａを積層する際に発生する位置ずれを防止する。熱交換器１ａの側面における気流の遮蔽は、図４（ｃ）に示すように隣接する第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａ同士が重なり合うことにより行われ、遮蔽リブ凹部８の凹部と遮蔽リブ凸部１６の凸部の嵌合も気流の遮蔽を行う。この明細書では、金型の製造精度と樹脂成形の精度を考慮して、第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａは必ず重なり合うようにし、遮蔽リブ凹部８と遮蔽リブ凸部１６の嵌合は、気流が漏れない程度に高さ方向に０．１ｍｍの積層逃がし部２０ａを設けた。なお０．１ｍｍの高さ方向の積層逃がし部２０ａを設けたが、単位素子２ａを正しく積層した時には、熱交換器１ａの側面における気流の遮蔽と単位素子２ａ同士の嵌合ができれば良く、熱交換器の設計や製造精度により適宜決定する。   As shown in FIGS. 4 (a), 4 (b), and 4 (c), the shielding rib recesses 8 and the shielding rib projections 16 are adjacent to each other when the unit elements 2a are correctly stacked while rotating 90 degrees alternately. The concave portion of the rib concave portion 8 and the convex portion of the shielding rib convex portion 16 are formed to be fitted. In the heat exchanger 1a, the unit elements 2a are fixed to each other by the fitting of the shielding rib recesses 8 and the shielding rib projections 16 provided in the first shielding rib 7a and the second shielding rib 7aa, and the unit elements 2a This prevents the positional deviation that occurs when the layers are stacked. The airflow shielding on the side surface of the heat exchanger 1a is performed by overlapping the adjacent first shielding rib 7a and second shielding rib 7aa as shown in FIG. The fitting of the convex portions of the shielding rib convex portion 16 also shields the airflow. In this specification, in consideration of mold manufacturing accuracy and resin molding accuracy, the first shielding rib 7 a and the second shielding rib 7 aa are always overlapped, and the shielding rib recess 8 and the shielding rib projection 16 are formed. For the fitting, a stacking relief portion 20a of 0.1 mm was provided in the height direction to such an extent that airflow did not leak. Although the stacking relief part 20a in the height direction of 0.1 mm is provided, when the unit elements 2a are correctly stacked, it is only necessary to shield the air flow on the side surface of the heat exchanger 1a and fit the unit elements 2a to each other. It is determined appropriately according to the design and manufacturing accuracy of the exchanger.

図５（ａ）、５（ｂ）に示すように、単位素子２ａを交互に９０度回転せず、誤って積層した時には、遮蔽リブ凸部１６の凸部は隣接する第一の間隔リブ６ａと干渉し、隣接する単位素子２ａ同士が嵌合できず、熱交換器１ａの側面から確認すると単位素子２ａ同士に隙間があり、容易に単位素子２ａの積み間違いを確認することができる。   As shown in FIGS. 5 (a) and 5 (b), when the unit elements 2a are not rotated alternately by 90 degrees and are stacked incorrectly, the projections of the shielding rib projections 16 are adjacent to the first spacing ribs 6a. The adjacent unit elements 2a cannot be fitted to each other, and when confirmed from the side surface of the heat exchanger 1a, there is a gap between the unit elements 2a, and it is possible to easily confirm the stacking error of the unit elements 2a.

熱交換器１ａは、単位素子２ａを積層した際に積み間違いが分かる手段として、第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａに遮蔽リブ凹部８と遮蔽リブ凸部１６を備えたことにより、単位素子２ａを正しく積層した時には隣接する単位素子２ａの遮蔽リブ凹部８の凹部と遮蔽リブ凸部１６の凸部が嵌合し、誤って積層した時には遮蔽リブ凸部１６の凸部と隣接する単位素子２ａの一部（第一の間隔リブ６ａ）が干渉するため、単位素子２ａの積み間違いを容易に確認することができる構成となっている。   The heat exchanger 1a is provided with the shielding rib concave portion 8 and the shielding rib convex portion 16 on the first shielding rib 7a and the second shielding rib 7aa as means for understanding the stacking error when the unit elements 2a are stacked. When the unit elements 2a are correctly laminated, the concave portions of the shielding rib concave portions 8 of the adjacent unit elements 2a and the convex portions of the shielding rib convex portions 16 are fitted, and when the unit elements 2a are mistakenly laminated, the convex portions of the shielding rib convex portions 16 are adjacent. Since a part of the unit element 2a (the first spacing rib 6a) interferes, the unit element 2a can be easily checked for stacking errors.

なお遮蔽リブ凹部８および遮蔽リブ凸部１６は単位素子２ａの第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａに設けたが、単位素子を正しく積層した時には隣接する単位素子の凹部と凸部が嵌合し、誤って積層した時には凸部と隣接する単位素子の一部が干渉する構造であれば、その他の構成の熱交換器を用いても同様の作用効果を得ることができる。   The shielding rib concave portion 8 and the shielding rib convex portion 16 are provided on the first shielding rib 7a and the second shielding rib 7aa of the unit element 2a. However, when the unit elements are correctly stacked, the concave portion and the convex portion of the adjacent unit element are provided. As long as they are fitted and mistakenly stacked, a part of the unit element adjacent to the convex part interferes, and the same effect can be obtained even if a heat exchanger having another configuration is used.

この明細書における干渉とは、単位素子２ａを誤って積層した時に凸部と隣接する単位素子２ａの一部が当たり、隣接する単位素子２ａ同士が嵌合できず隙間ができる状態のことである。また、単位素子２ａを正しく積層するとは、単位素子２ａに備えた凹部と凸部の嵌合構造が互いに嵌合し、気流の漏れが無く、熱交換器の基本性能が発揮できる状態のことであり、単位素子２ａを誤って積層するとは、単位素子２ａに備えた凸部と単位素子２ａの一部が干渉し、隣接する単位素子２ａの間に隙間ができ、気流の漏れが有り、熱交換器の基本性能が発揮できない状態のことである。   The interference in this specification is a state in which when the unit elements 2a are mistakenly stacked, a part of the unit elements 2a adjacent to the convex portion hits, and the adjacent unit elements 2a cannot be fitted to each other and a gap is formed. . In addition, when the unit elements 2a are correctly laminated, the concave and convex fitting structures provided in the unit elements 2a are fitted to each other, there is no airflow leakage, and the basic performance of the heat exchanger can be exhibited. Yes, if the unit elements 2a are mistakenly stacked, the convex portions provided in the unit elements 2a and a part of the unit elements 2a interfere with each other, a gap is formed between the adjacent unit elements 2a, airflow is leaked, This means that the basic performance of the exchanger cannot be demonstrated.

図６（ａ）、６（ｂ）、６（ｃ）に示すように、第一の凹部および第一の凸部として設けた貫通穴凹部１７と貫通穴凸部１０は単位素子２ａを交互に９０度回転しながら正しく積層した時には、隣接する貫通穴凹部１７の凹部と貫通穴凸部１０の凸部が嵌合するよう形成される。熱交換器１ａは単位素子２ａの四隅に設けた貫通穴凹部１７と貫通穴凸部１０の嵌合により、単位素子２ａ同士が互いに固定化され、且つ単位素子２ａを積層する際に発生する位置ずれを防止する。熱交換器１ａの四隅における気流の遮蔽は、図６（ｃ）に示すように隣接する第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａ同士が重なり合うことにより行われ、貫通穴凹部１７の凹部と貫通穴凸部１０の凸部の嵌合も気流の遮蔽を行う。この明細書では、金型の製造精度と樹脂成形の精度を考慮して、第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａは必ず重なり合うようにし、貫通穴凹部１７と貫通穴凸部１０の嵌合は、気流が漏れない程度に高さ方向に０．１ｍｍの積層逃がし部２０ｂを設けた。なお０．１ｍｍの高さ方向の積層逃がし部２０ｂを設けたが、単位素子２ａを正しく積層した時には、熱交換器１ａの四隅における気流の遮蔽と単位素子２ａ同士の嵌合ができれば良く、熱交換器の設計や製造精度により適宜決定する。   As shown in FIGS. 6 (a), 6 (b), and 6 (c), the through-hole recess 17 and the through-hole protrusion 10 provided as the first recess and the first protrusion alternately form the unit elements 2a. When correctly stacked while rotating 90 degrees, the concave portions of the adjacent through hole concave portions 17 and the convex portions of the through hole convex portions 10 are formed so as to be fitted. The heat exchanger 1a is a position generated when the unit elements 2a are stacked and the unit elements 2a are stacked by fitting the through-hole concave portions 17 and the through-hole convex portions 10 provided at the four corners of the unit elements 2a. Prevent misalignment. Airflow shielding at the four corners of the heat exchanger 1a is performed by overlapping the adjacent first shielding rib 7a and second shielding rib 7aa as shown in FIG. The fitting of the projections of the through-hole projections 10 also shields the airflow. In this specification, in consideration of mold manufacturing accuracy and resin molding accuracy, the first shielding rib 7a and the second shielding rib 7aa are necessarily overlapped, and the through-hole concave portion 17 and the through-hole convex portion 10 For the fitting, a stacking relief portion 20b of 0.1 mm was provided in the height direction to such an extent that the airflow did not leak. Although the stacking relief part 20b in the height direction of 0.1 mm is provided, when the unit elements 2a are correctly stacked, it is only necessary to shield the air flow at the four corners of the heat exchanger 1a and fit the unit elements 2a to each other. It is determined appropriately according to the design and manufacturing accuracy of the exchanger.

なお貫通穴凹部１７および貫通穴凸部１０は単位素子２ａの単位素子２ａの四隅に設けたが、単位素子を正しく積層した時には隣接する単位素子の凹部と凸部が嵌合し、間隔リブまたは遮蔽リブの少なくとも何れか、または間隔リブまたは遮蔽リブの少なくとも何れかに連結する構造であれば、その他の構成の熱交換器を用いても同様の作用効果を得ることができる。   The through-hole concave portion 17 and the through-hole convex portion 10 are provided at the four corners of the unit element 2a of the unit element 2a. However, when the unit elements are correctly stacked, the concave and convex portions of the adjacent unit elements are fitted, As long as the structure is connected to at least one of the shielding ribs, or at least one of the spacing ribs and the shielding ribs, the same operation and effect can be obtained even if a heat exchanger having another configuration is used.

図６（ａ）、６（ｂ）、６（ｃ）に示すように、第二の凹部および第二の凸部として設けた積層確認凹部１８と積層確認凸部１１は単位素子２ａを交互に９０度回転しながら正しく積層した時には、隣接する積層確認凹部１８の凹部と積層確認凸部１１の凸部が嵌合するよう形成される。熱交換器１ａは方形の単位素子２ａの対角する２箇所に設けた積層確認凹部１８と積層確認凸部１１の嵌合により、単位素子２ａ同士が互いに固定化され、且つ単位素子２ａを積層する際に発生する位置ずれを防止する。熱交換器１ａの四隅における気流の遮蔽は、図６（ｃ）に示すように隣接する第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａ同士が重なり合うことにより行われ、積層確認凹部１８の凹部と積層確認凸部１１の凸部の嵌合も気流の遮蔽を行う。この明細書では、金型の製造精度と樹脂成形の精度を考慮して、第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａは必ず重なり合うようにし、積層確認凹部１８と積層確認凸部１１の嵌合は、気流が漏れない程度に高さ方向に０．１ｍｍの積層逃がし部２０ｃを設けた。なお０．１ｍｍの高さ方向の積層逃がし部２０ｃを設けたが、単位素子２ａを正しく積層した時には、熱交換器１ａの四隅における気流の遮蔽と単位素子２ａ同士の嵌合ができれば良く、熱交換器の設計や製造精度により適宜決定する。   As shown in FIGS. 6 (a), 6 (b), and 6 (c), the stacking confirmation recesses 18 and the stacking confirmation projections 11 provided as the second recesses and the second projections alternately form the unit elements 2a. When the layers are correctly laminated while rotating 90 degrees, the concave portions of the adjacent lamination confirmation concave portions 18 and the convex portions of the lamination confirmation convex portions 11 are formed to be fitted. In the heat exchanger 1a, the unit elements 2a are fixed to each other and the unit elements 2a are stacked by fitting the stacking confirmation concave portions 18 and the stacking confirmation convex portions 11 provided at two diagonal positions of the square unit element 2a. This prevents misalignment that occurs when Airflow shielding at the four corners of the heat exchanger 1a is performed by overlapping the adjacent first shielding rib 7a and second shielding rib 7aa as shown in FIG. And the fitting of the convex portions of the stacking confirmation convex portion 11 also shields the airflow. In this specification, in consideration of mold manufacturing accuracy and resin molding accuracy, the first shielding rib 7a and the second shielding rib 7aa are necessarily overlapped, and the stacking confirmation concave portion 18 and the stacking confirmation convex portion 11 are formed. For the fitting, a stacking relief portion 20c of 0.1 mm was provided in the height direction to such an extent that airflow did not leak. Although the stacking relief portion 20c in the height direction of 0.1 mm is provided, when the unit elements 2a are correctly stacked, it is only necessary to shield the airflow at the four corners of the heat exchanger 1a and fit the unit elements 2a to each other. It is determined appropriately according to the design and manufacturing accuracy of the exchanger.

図７（ａ）、７（ｂ）、７（ｃ）に示すように、単位素子２ａを交互に９０度回転せず、誤って積層した時には、積層確認凸部１１の凸部は隣接する第二の遮蔽リブ７ａａと干渉し、隣接する単位素子２ａ同士が嵌合できず、熱交換器１ａの側面から確認すると単位素子２ａ同士に隙間があり、容易に単位素子２ａの積み間違いを確認することができる構成となっている。   As shown in FIGS. 7 (a), 7 (b), and 7 (c), when the unit elements 2a are not rotated alternately by 90 degrees and are stacked incorrectly, the protrusions of the stacking confirmation protrusion 11 are adjacent to each other. Interfering with the two shielding ribs 7aa, the adjacent unit elements 2a cannot be fitted to each other, and when confirmed from the side surface of the heat exchanger 1a, there is a gap between the unit elements 2a, and it is easy to confirm a stacking error of the unit elements 2a. It has a configuration that can.

なお積層確認凹部１８および積層確認凸部１１は単位素子２ａの対角にそれぞれ２個設けたが、単位素子を正しく積層した時には隣接する単位素子の凹部と凸部が嵌合し、誤って積層した時には凸部と隣接する単位素子の一部が干渉する構造であれば、その他の構成の熱交換器を用いても同様の作用効果を得ることができる。   Although the stacking confirmation recess 18 and the stacking confirmation protrusion 11 are provided at two diagonals of the unit element 2a, when the unit elements are correctly stacked, the recesses and the projections of the adjacent unit elements are fitted to each other and the stacking is erroneously performed. In this case, if the structure is such that a part of the unit element adjacent to the convex portion interferes, the same operation and effect can be obtained even if a heat exchanger having another configuration is used.

図８に示す伝熱板４は一辺が１１９ｍｍの方形で、厚さが０．２〜０．０１ｍｍ、好ましくは０．１〜０．０１ｍｍの和紙、防燃紙、伝熱性と透湿性と気体遮蔽性を有する特殊加工紙、透湿膜、または伝熱性のみを有するポリエステル系、ポリスチレン系のＡＢＳ、ＡＳ、ＰＳ、ポリオレフィン系のＰＰ、ＰＥなどの樹脂シート、樹脂フィルムなどで構成される。伝熱板４の四隅には貫通穴９を４個設け、方形の伝熱板４の一つの対角線上に位置決め穴２１を２個設け、この伝熱板４を樹脂金型に挿入し、インサート射出成形を用いて単位素子２ａを一体成形する。伝熱板４を樹脂金型内に挿入する際、伝熱板４を位置決め、固定するためのピンを樹脂金型に設けておき、樹脂金型のピンと伝熱板４の位置決め穴２１によって伝熱板４の位置決めを行う。   The heat transfer plate 4 shown in FIG. 8 has a rectangular shape with a side of 119 mm and a thickness of 0.2 to 0.01 mm, preferably 0.1 to 0.01 mm, Japanese paper, flameproof paper, heat transfer, moisture permeability, and gas. It is composed of a specially processed paper having a shielding property, a moisture permeable film, or a resin sheet such as polyester, polystyrene, ABS, AS, PS, polyolefin PP or PE having only heat conductivity, a resin film, or the like. Four through-holes 9 are provided at the four corners of the heat transfer plate 4, two positioning holes 21 are provided on one diagonal line of the square heat transfer plate 4, and the heat transfer plate 4 is inserted into a resin mold. The unit element 2a is integrally formed using injection molding. When the heat transfer plate 4 is inserted into the resin mold, a pin for positioning and fixing the heat transfer plate 4 is provided in the resin mold, and the heat transfer plate 4 and the positioning hole 21 of the heat transfer plate 4 are used to transfer the heat transfer plate 4. The hot plate 4 is positioned.

図９（ａ）、９（ｂ）、９（ｃ）に示すように、位置決め貫通穴１３ａ、１３ａａは伝熱板４の位置決め穴２１の周囲に形成され、位置決め凸部１２の凸部は単位素子２ａを交互に９０度回転しながら正しく積層した時には、隣接する位置決め貫通穴１３ａ、１３ａａと嵌合するように形成され、位置決め平面部１９は隣接する位置決め貫通穴１３ａの穴を塞ぐように形成される。   As shown in FIGS. 9A, 9B, and 9C, the positioning through holes 13a and 13aa are formed around the positioning hole 21 of the heat transfer plate 4, and the convex portion of the positioning convex portion 12 is a unit. When the elements 2a are correctly stacked while being alternately rotated by 90 degrees, they are formed so as to be fitted to the adjacent positioning through holes 13a, 13aa, and the positioning flat portion 19 is formed so as to block the holes of the adjacent positioning through holes 13a. Is done.

熱交換器１ａは単位素子２ａの対角線上に設けた位置決め貫通穴１３ａ、１３ａａと位置決め凸部１２の嵌合により、単位素子２ａ同士が互いに固定化され、且つ単位素子２ａを積層する際に発生する位置ずれを防止する。熱交換器１ａの中央部における気流の遮蔽は、図９（ｃ）に示すように隣接する位置決め平面部１９と位置決め貫通穴１３ａおよび位置決め凸部１２の凸部下面と位置決め貫通穴１３ａａが重なり合うことにより行われ、位置決め貫通穴１３ａ、１３ａａの穴と位置決め凸部１２の凸部の嵌合も気流の遮蔽を行う。この明細書では、金型の製造精度と樹脂成形の精度を考慮して、位置決め平面部１９と位置決め貫通穴１３ａおよび位置決め凸部１２の凸部下面と位置決め貫通穴１３ａａは必ず重なり合うようにし、位置決め貫通穴１３ａ、１３ａａと位置決め凸部１２の嵌合は、気流が漏れない程度に高さ方向に０．３ｍｍの積層逃がし部２０ｄを設けた。なお０．３ｍｍの高さ方向の積層逃がし部２０ｄを設けたが、単位素子２ａを正しく積層した時には、熱交換器１ａの中央部における気流の遮蔽と単位素子２ａ同士の嵌合ができれば良く、熱交換器の設計や製造精度により適宜決定する。   The heat exchanger 1a occurs when the unit elements 2a are fixed to each other by stacking the unit elements 2a by fitting the positioning through holes 13a, 13aa provided on the diagonal line of the unit elements 2a and the positioning projections 12 to each other. To prevent misalignment. As shown in FIG. 9C, the airflow shielding at the central portion of the heat exchanger 1a is such that the adjacent positioning flat surface portion 19 and positioning through hole 13a and the bottom surface of the positioning convex portion 12 overlap the positioning through hole 13aa. The fitting of the positioning through holes 13a and 13aa and the convex portions of the positioning convex portion 12 also shields the airflow. In this specification, in consideration of mold manufacturing accuracy and resin molding accuracy, the positioning flat surface portion 19 and the positioning through-hole 13a and the lower surface of the positioning convex portion 12 and the positioning through-hole 13aa are always overlapped, The through holes 13a, 13aa and the positioning convex portion 12 were fitted with a 0.3 mm laminated escape portion 20d in the height direction so as not to leak airflow. Although the stacking relief part 20d in the height direction of 0.3 mm is provided, when the unit elements 2a are correctly stacked, it is only necessary to shield the air flow at the center of the heat exchanger 1a and to fit the unit elements 2a, It is determined as appropriate according to the design and manufacturing accuracy of the heat exchanger.

図１０（ａ）、１０（ｂ）、１０（ｃ）に示すように、単位素子２ａを交互に９０度回転せず、誤って積層した時には、位置決め凸部１２の凸部は隣接する位置決め平面部１９と干渉し、隣接する単位素子２ａ同士が嵌合できず、熱交換器１ａの側面から確認すると単位素子２ａ同士に隙間があり、容易に単位素子２ａの積み間違いを確認することができる構成となっている。   As shown in FIGS. 10 (a), 10 (b), and 10 (c), when the unit elements 2a are not rotated alternately by 90 degrees and are stacked by mistake, the convex portions of the positioning convex portions 12 are adjacent to the positioning planes. When the unit elements 2a interfere with each other and cannot be fitted to each other and are confirmed from the side surface of the heat exchanger 1a, there is a gap between the unit elements 2a, and it is possible to easily check the stacking error of the unit elements 2a. It has a configuration.

なお、位置決め貫通穴１３ａ、１３ａａ、位置決め凸部１２および位置決め平面部１９は単位素子２ａの対角線上にそれぞれ２個設けたが、単位素子を正しく積層した時には隣接する単位素子の穴と凸部が嵌合し、誤って積層した時には凸部と隣接する単位素子の一部が干渉する構造であれば、その他の構成の熱交換器を用いても同様の作用効果を得ることができる。   The positioning through-holes 13a, 13aa, the positioning convex portion 12 and the positioning flat portion 19 are each provided on the diagonal of the unit element 2a. However, when the unit elements are correctly stacked, the holes and convex portions of the adjacent unit elements are not formed. Similar effects can be obtained even if heat exchangers with other configurations are used as long as they have a structure in which a part of the unit element adjacent to the convex portion interferes when they are fitted and mistakenly stacked.

図６（ｃ）、図８に示すように、伝熱板４と樹脂を一体成形して形成された単位素子２ａにおいて、伝熱板４の貫通穴９は第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａの貫通穴９と同じ位置で、単位素子２ａに貫通する穴が形成され、この穴の周囲に貫通穴凸部１０および貫通穴凹部１７が形成される。   As shown in FIGS. 6C and 8, in the unit element 2a formed by integrally molding the heat transfer plate 4 and the resin, the through hole 9 of the heat transfer plate 4 has the first shielding rib 7a and the second shielding rib 7a. A hole penetrating the unit element 2a is formed at the same position as the through hole 9 of the shielding rib 7aa, and the through hole convex portion 10 and the through hole concave portion 17 are formed around the hole.

図６（ｃ）、図９（ｃ）に示すように、貫通穴９、貫通穴凸部１０および貫通穴凹部１７は第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａに連結する位置に構成し、位置決め貫通穴１３ａ、１３ａａ、位置決め凸部１２および位置決め平面部１９は第一の間隔リブ６ａ、第二の間隔リブ６ａａに連結する位置に構成しているため、一回の樹脂成形でこれらを有する単位素子２ａが形成できる。   As shown in FIG. 6C and FIG. 9C, the through hole 9, the through hole convex portion 10, and the through hole concave portion 17 are configured to be connected to the first shielding rib 7a and the second shielding rib 7aa. Since the positioning through holes 13a, 13aa, the positioning convex portion 12 and the positioning flat surface portion 19 are configured to be connected to the first spacing rib 6a and the second spacing rib 6aa, these are formed by a single resin molding. Can be formed.

なお、貫通穴９、貫通穴凸部１０および貫通穴凹部１７は第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａに連結する位置に形成し、位置決め貫通穴１３ａ、１３ａａ、位置決め凸部１２および位置決め平面部１９は第一の間隔リブ６ａ、第二の間隔リブ６ａａに連結する位置に形成したが、貫通穴９、貫通穴凸部１０、貫通穴凹部１７、位置決め貫通穴１３ａ、１３ａａ、位置決め凸部１２および位置決め平面部１９は第一の間隔リブ６ａ、第二の間隔リブ６ａａまたは第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａの少なくとも何れか、または第一の間隔リブ６ａ、第二の間隔リブ６ａａまたは第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａの少なくとも何れかに連結する位置に設け、伝熱板４と樹脂を一体成形して単位素子２ａを得る際に、一回の樹脂成形で一体に形成できれば良く、その他の構成を用いても同様の作用効果を得ることができる。   The through-hole 9, the through-hole convex portion 10 and the through-hole concave portion 17 are formed at positions where they are connected to the first shielding rib 7a and the second shielding rib 7aa, and the positioning through-holes 13a and 13aa, the positioning convex portion 12 and The positioning flat surface portion 19 is formed at a position connected to the first spacing rib 6a and the second spacing rib 6aa. However, the through-hole 9, the through-hole convex portion 10, the through-hole concave portion 17, the positioning through-holes 13a and 13aa, and the positioning The convex portion 12 and the positioning flat surface portion 19 include at least one of the first spacing rib 6a, the second spacing rib 6aa or the first shielding rib 7a, the second shielding rib 7aa, or the first spacing rib 6a, When the unit element 2a is obtained by integrally forming the heat transfer plate 4 and the resin at a position where it is connected to at least one of the second spacing rib 6aa, the first shielding rib 7a, and the second shielding rib 7aa. If integrally formed with the resin molded well, it is possible to obtain the same effect even by using other configurations.

次の成形工程２３は伝熱板４を射出成形金型２４に挿入し、射出成形機にて伝熱板４と樹脂を一体成形するインサート射出成形工法で単位素子２ａが得られる。この樹脂としては熱可塑性樹脂を適用し、樹脂の種類としては、ポリエステル系、ポリスチレン系のＡＢＳ、ＡＳ、ＰＳ、またはポリオレフィン系のＰＰ、ＰＥなどが用いられる。また熱可塑性樹脂の中にガラス繊維または炭素繊維の無機充填剤を添加した樹脂を用いても良い。無機充填剤の添加量は樹脂の重量に対して１〜５０重量％、更に好ましくは１０〜３０重量％であり、樹脂に無機充填剤を添加すると、樹脂成形品の単位素子２ａは強度と反りや収縮性の物性が向上することと、一体成形する伝熱板４と樹脂との接着性が向上する。これは化学結合による接着性が向上するのではなく、無機充填剤と伝熱板４との繊維の絡まりが強くなった物理結合が向上するものである。無機充填剤の添加量は樹脂の重量に対して多く混入すると、樹脂成形品の強度と反りや収縮性の物性が向上するが、５０重量％以上になると、射出成形する時の溶融した樹脂の流動性が低下するため、樹脂成形品が得られない場合があり、無機充填剤の添加量は樹脂成形品の必要強度、樹脂物性、射出成形機の仕様などにより適宜決定する。   In the next molding step 23, the unit element 2a is obtained by an insert injection molding method in which the heat transfer plate 4 is inserted into the injection mold 24 and the heat transfer plate 4 and the resin are integrally formed by an injection molding machine. As this resin, a thermoplastic resin is applied. As the type of resin, polyester-based, polystyrene-based ABS, AS, PS, polyolefin-based PP, PE, or the like is used. Further, a resin obtained by adding an inorganic filler of glass fiber or carbon fiber to a thermoplastic resin may be used. The addition amount of the inorganic filler is 1 to 50% by weight, more preferably 10 to 30% by weight with respect to the weight of the resin. When the inorganic filler is added to the resin, the unit element 2a of the resin molded product has strength and warpage. In addition, the shrinkable physical properties are improved, and the adhesion between the heat transfer plate 4 and the resin to be integrally molded is improved. This does not improve the adhesiveness due to the chemical bond, but improves the physical bond in which the fiber entanglement between the inorganic filler and the heat transfer plate 4 becomes strong. If a large amount of the inorganic filler is added relative to the weight of the resin, the strength, warpage and shrinkage properties of the resin molded product will be improved. Since the fluidity decreases, a resin molded product may not be obtained, and the amount of the inorganic filler added is appropriately determined depending on the required strength of the resin molded product, the physical properties of the resin, the specifications of the injection molding machine, and the like.

この成形工程２３は、溶融した樹脂を伝熱板４のＸ方向からから射出成形金型２４内に射出すると、樹脂流路を通り、金型のゲート部から単位素子２ａに設けた遮蔽リブ注入口１４ａおよび間隔リブ注入口１５から流入し、更に溶融した樹脂は射出圧力が高いため、伝熱板４のＸ方向表面の第一の間隔リブ６ａおよび第一の遮蔽リブ７ａを成形すると共に、和紙などの紙類で構成された伝熱板４を貫通し、伝熱板４Ｙ方向表面の第二の間隔リブ６ａａおよび第二の遮蔽リブ７ａａと連結する形で形成することができるので、一回の成形で伝熱板４と第一の間隔リブ６ａ、第二の間隔リブ６ａａと第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａを有する単位素子２ａを形成することができる。   In this molding step 23, when the molten resin is injected into the injection mold 24 from the X direction of the heat transfer plate 4, it passes through the resin flow path and the shielding rib provided on the unit element 2a from the gate portion of the mold. Since the molten resin flowing in from the inlet 14a and the interval rib injection port 15 and the molten resin has a high injection pressure, the first interval rib 6a and the first shielding rib 7a on the surface in the X direction of the heat transfer plate 4 are formed, Since it can be formed so as to penetrate the heat transfer plate 4 made of paper such as Japanese paper and to be connected to the second spacing rib 6aa and the second shielding rib 7aa on the surface of the heat transfer plate 4Y. The unit element 2a having the heat transfer plate 4 and the first spacing rib 6a, the second spacing rib 6aa, the first shielding rib 7a, and the second shielding rib 7aa can be formed by one-time molding.

単位素子２ａを樹脂成形する射出成形金型２４はランナーレスにする手段を備え、ランナーレスにする手段として、オープンゲート式またはバルブゲート式のホットランナーを使用する。ヒータ２５によりランナー・ゲート部を加熱制御して溶融樹脂を常に流動化状態に保てるため、樹脂成形時に廃材となるスプル・ランナー２６が出ず、樹脂材料費削減と省資源化することができる。また成形品の単位素子２ａのみを射出成形金型２４から連続的に取り出せるので成形サイクルを短縮することができる。   The injection mold 24 for resin-molding the unit element 2a includes a runner-less means, and an open-gate or valve-gate hot runner is used as a runner-less means. Since the molten resin can always be kept fluidized by controlling the runner / gate portion with the heater 25, the sprue runner 26 which becomes a waste material at the time of resin molding does not come out, and the resin material cost can be reduced and the resources can be saved. Further, since only the unit element 2a of the molded product can be continuously taken out from the injection mold 24, the molding cycle can be shortened.

この明細書のスプルとは、射出成形金型２４において成形材料の流路の一部で円錐形の部分を指し、ランナーとは射出成形金型２４においてキャビティに溶融樹脂を流し込む径路のうち、スプルからゲートまでの部分を指す。   The sprue in this specification refers to a conical part of the flow path of the molding material in the injection mold 24, and the runner refers to the sprue of the paths through which molten resin flows into the cavity in the injection mold 24. The part from the gate to the gate.

またバルブゲート式のホットランナーはゲート開閉機能を有するので、溶融樹脂が射出成形金型２４から注入される単位素子２ａの遮蔽リブ注入口１４ａおよび間隔リブ注入口１５においてバリができないため、単位素子２ａを積層した際に隣接する単位素子２ａ同士がバリによって干渉することがなく、隙間無く単位素子２ａを積層することができる。   Further, since the valve gate type hot runner has a gate opening / closing function, the burr cannot be formed at the shielding rib injection port 14a and the interval rib injection port 15 of the unit element 2a into which the molten resin is injected from the injection mold 24. When the 2a is stacked, the adjacent unit elements 2a do not interfere with each other by burrs, and the unit elements 2a can be stacked without any gap.

次の積層工程２７は単位素子２ａを交互に９０度回転しながら積層し、単位素子２ａの四隅に設けた貫通穴９に支持棒３を挿入する工程である。   The next laminating step 27 is a step of laminating the unit elements 2a while alternately rotating by 90 degrees, and inserting the support bars 3 into the through holes 9 provided at the four corners of the unit elements 2a.

次の結束工程２８は貫通穴９に挿入した支持棒３の両端に止め具を付設し単位素子２ａ同士を結束することによって熱交換器１ａを得る工程である。また、支持棒３は熱可塑性樹脂などよりなるものであって、支持棒３の両端を熱によって溶融し単位素子２ａ同士を締め付けた状態で固化させることにより結束するものであってもよい。なお本発明における結束とは、単位素子２ａ同士を機械的拘束により固定化したものである。   The next bundling step 28 is a step of obtaining the heat exchanger 1a by attaching a stopper to both ends of the support rod 3 inserted into the through hole 9 and bundling the unit elements 2a. The support rod 3 may be made of a thermoplastic resin or the like, and may be bound by melting both ends of the support rod 3 with heat and solidifying the unit elements 2a in a clamped state. The term “bundling” in the present invention means that the unit elements 2a are fixed by mechanical restraint.

熱交換器１ａは第一の間隔リブ６ａおよび第一の遮蔽リブ７ａに連結する位置に溶融樹脂を注入する遮蔽リブ注入口１４ａおよび間隔リブ注入口１５を備え、第一の間隔リブ６ａ、第二の間隔リブ６ａａおよび第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａが何れかで連結している構成である。また遮蔽リブ注入口１４ａおよび間隔リブ注入口１５は、単位素子２ａを積層した時に隣接する単位素子２ａが干渉しないように逃がす手段を備え、逃がす手段として、第一の間隔リブ６ａおよび第一の遮蔽リブ７ａに段落としを設ける。また段落としとして第一の遮蔽リブ７ａに連結し、通風路５内に遮蔽リブ注入口１４ａを設ける。   The heat exchanger 1a includes a shielding rib inlet 14a and a spacing rib inlet 15 for injecting molten resin at positions connected to the first spacing rib 6a and the first shielding rib 7a. The second spacing rib 6aa, the first shielding rib 7a, and the second shielding rib 7aa are connected by any one of them. Further, the shielding rib injection port 14a and the interval rib injection port 15 include means for allowing the adjacent unit elements 2a not to interfere when the unit elements 2a are stacked, and the first interval rib 6a and the first interval ribs are used as the means for releasing. A paragraph is provided on the shielding rib 7a. Further, as a paragraph, it is connected to the first shielding rib 7 a and a shielding rib inlet 14 a is provided in the ventilation path 5.

図４（ａ）、４（ｂ）、４（ｃ）に示すように、遮蔽リブ注入口１４ａは通風路５内に段落としを設けたことにより、溶融樹脂が金型から注入される遮蔽リブ注入口１４ａにおいてバリが万一発生しても、単位素子２ａを積層した際に隣接する単位素子２ａ同士は段落しによってバリを逃がすことにより干渉せず、更に前記バリは通風路５内に位置するため、隣接する単位素子２ａとの通風路５空間によってバリを逃がすことにより更に干渉せず、隙間無く単位素子２ａを積層することができる。   As shown in FIGS. 4 (a), 4 (b), and 4 (c), the shielding rib injection port 14a is provided with a paragraph in the ventilation path 5, so that the molten resin is injected from the mold. Even if burrs are generated at the inlet 14a, the adjacent unit elements 2a do not interfere with each other when the unit elements 2a are stacked, and the burrs are located in the ventilation path 5 without interfering with each other. Therefore, the unit element 2a can be stacked without a gap without causing further interference by releasing the burr by the space of the ventilation path 5 with the adjacent unit element 2a.

図１３（ａ）、１３（ｂ）、１３（ｃ）に示すように、第一の間隔リブ６ａに設けた間隔リブ注入口１５は単位素子２ａを交互に９０度回転しながら正しく積層した時には、隣接する第二の間隔リブ６ａａと重なり合うが、間隔リブ注入口１５は第一の間隔リブ６ａの上面に凹高さ０．５ｍｍに第一の間隔リブ６ａを段落しするような形状のため、溶融樹脂が金型から注入される間隔リブ注入口１５においてバリが万一発生しても、単位素子２ａを積層した際に隣接する単位素子２ａ同士は逃がす手段によってバリを逃がすことにより干渉せず、隙間無く単位素子２ａを積層することができる。   As shown in FIGS. 13 (a), 13 (b), and 13 (c), when the interval rib injection port 15 provided in the first interval rib 6a is correctly stacked while alternately rotating the unit elements 2a by 90 degrees. The gap rib inlet 15 overlaps with the adjacent second gap rib 6aa, but has a shape that forms the first gap rib 6a with a concave height of 0.5 mm on the upper surface of the first gap rib 6a. Even if burrs are generated at the interval rib injection port 15 where molten resin is injected from the mold, when the unit elements 2a are stacked, the adjacent unit elements 2a interfere with each other by releasing the burrs. Therefore, the unit elements 2a can be stacked without a gap.

この明細書における段落しとは、溶融樹脂が金型から単位素子２ａに注入される注入口において、バリが万一発生しても、単位素子２ａを積層した際に隣接する単位素子２ａ同士が干渉しないように、周囲の樹脂リブより凸高さを下げることである。   In this specification, the term “paragraph” means that even if burrs occur at the injection port through which molten resin is injected from the mold into the unit element 2a, the adjacent unit elements 2a are stacked when the unit elements 2a are stacked. In order to avoid interference, the convex height is lowered from the surrounding resin ribs.

なお、間隔リブ注入口１５の段落しは第一の間隔リブ６ａの上面に設け、遮蔽リブ注入口１４ａの段落しは第一の遮蔽リブ７ａに連結するように設けたが、溶融樹脂を注入する注入口は、第一の間隔リブ６ａまたは第一の遮蔽リブ７ａの少なくとも何れかに連結し、通風路５内に設け、バリを逃がすように段落しにする構成であれば良く、その他の構成を用いても同様の作用効果を得ることができる。   The gap rib inlet 15 is provided on the upper surface of the first gap rib 6a, and the shield rib inlet 14a is provided so as to be connected to the first shield rib 7a. The inlet to be connected may be connected to at least one of the first spacing rib 6a or the first shielding rib 7a, provided in the ventilation path 5, and may be configured to be separated so as to escape the burr. Even if the configuration is used, the same effect can be obtained.

上記構成により、熱交換器１ａは、単位素子２ａを積層した際に積み間違いが分かる手段として、第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａに遮蔽リブ凹部８と遮蔽リブ凸部１６を備えたことにより、単位素子２ａを正しく積層した時には隣接する単位素子２ａの遮蔽リブ凹部８の凹部と遮蔽リブ凸部１６の凸部が嵌合し、誤って積層した時には遮蔽リブ凸部１６の凸部と隣接する単位素子２ａの一部（第一の間隔リブ６ａ）が干渉するため、単位素子２ａの積み間違いを容易に確認することができ、積み間違いを修正することによって生産工程の不良を低減することができ、量産性を向上することができる。また単位素子２ａの積み間違いに起因する密封性の低下を防止することができ、気流の漏れを防止することができる。また遮蔽リブ凹部８の凹部と遮蔽リブ凸部１６の凸部は単位素子２ａを積層した際に凹部と凸部が嵌合することにより、単位素子２ａ同士が互いに固定するため、単位素子２ａのずれに起因する密封性の低下を防止することができ、気流の漏れを防止することができ、また前記嵌合構造が単位素子２ａを積層する際に発生する位置ずれを防止することにより、量産性を向上することができる。   With the above configuration, the heat exchanger 1a has the first and second shielding ribs 7a and 7aa with the shielding rib concave portion 8 and the shielding rib convex portion 16 as means for understanding the stacking error when the unit elements 2a are stacked. As a result, when the unit elements 2a are correctly stacked, the concave portions of the shielding rib concave portions 8 of the adjacent unit elements 2a and the convex portions of the shielding rib convex portions 16 are fitted. Since a part of the unit element 2a adjacent to the convex portion (first spacing rib 6a) interferes, it is possible to easily check the stacking error of the unit elements 2a, and to correct the stacking error, thereby causing a defective production process. Can be reduced, and mass productivity can be improved. In addition, it is possible to prevent the sealing performance from being lowered due to erroneous stacking of the unit elements 2a, and to prevent airflow leakage. Further, since the concave portion of the shielding rib concave portion 8 and the convex portion of the shielding rib convex portion 16 are fixed to each other by fitting the concave portion and the convex portion when the unit elements 2a are stacked, the unit elements 2a are fixed to each other. Decrease in sealing performance due to misalignment can be prevented, airflow leakage can be prevented, and the fitting structure can prevent mass misalignment that occurs when the unit elements 2a are stacked. Can be improved.

また単位素子２ａの積み間違いによって、伝熱板４毎に同じ方向に通風路５が形成され、一次気流Ａと二次気流Ｂを熱交換器１ａに流通すると、誤って積層した部分については熱交換がされない。単位素子２ａを積層した際に積み間違いが分かる手段を備えたことにより、単位素子２ａの積み間違いによって、伝熱板４毎に正しく通風路５が形成できないことに起因する熱交換効率の低下を防止することができる。   Further, when the unit elements 2a are stacked incorrectly, the ventilation path 5 is formed in the same direction for each heat transfer plate 4, and when the primary airflow A and the secondary airflow B are circulated through the heat exchanger 1a, Not exchanged. By providing means for understanding the stacking error when the unit elements 2a are stacked, the heat exchange efficiency is reduced due to the fact that the ventilation path 5 cannot be formed correctly for each heat transfer plate 4 due to the stacking error of the unit elements 2a. Can be prevented.

また熱交換器１ａは、単位素子２ａに貫通穴９と、第一の凹部と第一の凸部として貫通穴凹部１７および貫通穴凸部１０と、第二の凹部と第二の凸部として積層確認凹部１８および積層確認凸部１１を備えたことにより、第一の凹部と第一の凸部は単位素子２ａを積層した際に貫通穴凹部１７と貫通穴凸部１０が嵌合することにより、単位素子２ａ同士が互いに固定するため、単位素子２ａのずれに起因する密封性の低下を防止することができ、気流の漏れを防止することができる。また貫通穴９の周囲に設けた前記第一の嵌合構造が、単位素子２ａを積層する際に発生する位置ずれを防止することにより量産性を向上することができる。更に第二の凹部と第二の凸部は単位素子２ａを正しく積層した時には隣接する単位素子２ａの積層確認凹部１８と積層確認凸部１１が嵌合し、誤って積層した時には積層確認凸部１１と隣接する単位素子２ａの一部（第二の遮蔽リブ７ａａ）が干渉するため、単位素子２ａの積み間違いを容易に確認することができ、積み間違いを修正することによって生産工程の不良を低減することができ、量産性を向上することができる。また単位素子２ａの積み間違いに起因する密封性の低下を防止することができ、気流の漏れを防止することができる。また第二の凹部と第二の凸部は単位素子２ａを積層した際に積層確認凹部１８と積層確認凸部１１が嵌合することにより、単位素子２ａ同士が互いに固定するため、単位素子２ａのずれに起因する密封性の低下を防止することができ、気流の漏れを防止することができ、また前記第二の嵌合構造が単位素子２ａを積層する際に発生する位置ずれを防止することにより、量産性を向上することができる。   Further, the heat exchanger 1a includes a through-hole 9 in the unit element 2a, a first concave portion and a first convex portion as a through-hole concave portion 17 and a through-hole convex portion 10, and a second concave portion and a second convex portion. By providing the stacking confirmation concave portion 18 and the stacking confirmation convex portion 11, the first concave portion and the first convex portion are fitted with the through hole concave portion 17 and the through hole convex portion 10 when the unit elements 2a are stacked. As a result, the unit elements 2a are fixed to each other, so that it is possible to prevent deterioration of the sealing performance due to the deviation of the unit elements 2a and to prevent airflow leakage. Further, the first fitting structure provided around the through hole 9 can prevent mass misalignment that occurs when the unit elements 2a are stacked, thereby improving mass productivity. Further, when the unit elements 2a are correctly stacked, the second concave portion and the second convex portion are fitted with the stacking confirmation concave portion 18 and the stacking confirmation convex portion 11 of the adjacent unit element 2a. 11 and a part (second shielding rib 7aa) of the adjacent unit element 2a interfere with each other, so that it is possible to easily check the stacking error of the unit elements 2a. It can be reduced and mass productivity can be improved. In addition, it is possible to prevent the sealing performance from being lowered due to erroneous stacking of the unit elements 2a, and to prevent airflow leakage. In addition, the second concave portion and the second convex portion are fixed to each other by uniting the stacking confirmation concave portion 18 and the stacking confirmation convex portion 11 when the unit elements 2a are stacked. It is possible to prevent the sealing performance from being lowered due to the deviation of the air flow, to prevent the leakage of the air flow, and to prevent the positional deviation that occurs when the second fitting structure stacks the unit elements 2a. Thus, mass productivity can be improved.

また熱交換器１ａは、単位素子２ａを積層した際に貫通穴９に支持棒３を通し、単位素子２ａ同士を結束したことにより、単位素子２ａのずれに起因する密封性の低下を防止することができ、気流の漏れを防止することができる。   Moreover, the heat exchanger 1a prevents the deterioration of the sealing performance due to the deviation of the unit elements 2a by passing the support rod 3 through the through hole 9 when the unit elements 2a are stacked and binding the unit elements 2a. And air flow leakage can be prevented.

また熱交換器１ａは、伝熱板４に位置決め穴２１を備え、単位素子２ａに位置決め貫通穴１３ａ、１３ａａと位置決め凸部１２と位置決め平面部１９を備えたことにより、金型内に伝熱板４を挿入してから射出成形するインサート射出成形を用いた場合、伝熱板４に設けた位置決め穴２１の穴は、樹脂金型に伝熱板４を挿入する際の位置決めを容易に行うことができ、量産性を向上することができる。また単位素子２ａを正しく積層した時には隣接する単位素子２ａの位置決め貫通穴１３ａ、１３ａａの穴と位置決め凸部１２の凸部が嵌合し、誤って積層した時には位置決め凸部１２の凸部と隣接する単位素子２ａの一部（位置決め平面部１９）が干渉するため、単位素子２ａの積み間違いを容易に確認することができ、積み間違いを修正することによって生産工程の不良を低減することができ、量産性を向上することができる。また単位素子２ａの積み間違いに起因する密封性の低下を防止することができ、気流の漏れを防止することができる。また貫通穴と凸部は単位素子２ａを積層した際に位置決め貫通穴１３ａ、１３ａａの穴と位置決め凸部１２の凸部が嵌合することにより、単位素子２ａ同士が互いに固定するため、単位素子２ａのずれに起因する密封性の低下を防止することができ、気流の漏れを防止することができ、また前記嵌合構造が単位素子２ａを積層する際に発生する位置ずれを防止することにより、量産性を向上することができる。   Further, the heat exchanger 1a is provided with the positioning hole 21 in the heat transfer plate 4, and the positioning through holes 13a and 13aa, the positioning convex portion 12, and the positioning flat surface portion 19 in the unit element 2a.

And mass productivity can be improved. Further, when the unit elements 2a are correctly stacked, the holes of the positioning through holes 13a and 13aa of the adjacent unit elements 2a and the convex portions of the positioning convex portions 12 are fitted, and when the unit elements 2a are erroneously stacked, adjacent to the convex portions of the positioning convex portions 12 Since a part of the unit element 2a (positioning plane part 19) interferes, it is possible to easily check the stacking error of the unit elements 2a, and it is possible to reduce defects in the production process by correcting the stacking error. , Mass productivity can be improved.

Since the heat plate 4 is integrally formed with the heat plate 4 interposed therebetween, a highly airtight unit element 2a can be formed. By stacking the unit elements 2a, a heat exchanger 1a that can prevent airflow leakage is obtained. It is done.

また熱交換器１ａは、単位素子２ａの第一の間隔リブ６ａ、第二の間隔リブ６ａａおよび第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａは何れかで連結し、且つ樹脂で構成されているため、第一の間隔リブ６ａ、第二の間隔リブ６ａａまたは第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａの少なくとも何れか、または第一の間隔リブ６ａ、第二の間隔リブ６ａａまたは第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａの少なくとも何れかに連結する位置に貫通穴９を設けたことにより、第一の間隔リブ６ａ、第二の間隔リブ６ａａと第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａと貫通穴９を有する単位素子２ａが一回の樹脂成形で一体に形成でき、量産性を向上することができる。   In the heat exchanger 1a, the first spacing rib 6a, the second spacing rib 6aa, the first shielding rib 7a, and the second shielding rib 7aa of the unit element 2a are connected to each other and are made of resin. Therefore, at least one of the first spacing rib 6a, the second spacing rib 6aa or the first shielding rib 7a, the second shielding rib 7aa, or the first spacing rib 6a, the second spacing rib 6aa. Alternatively, by providing the through hole 9 at a position connected to at least one of the first shielding rib 7a and the second shielding rib 7aa, the first spacing rib 6a, the second spacing rib 6aa and the first shielding rib. The unit element 2a having the rib 7a, the second shielding rib 7aa, and the through hole 9 can be integrally formed by a single resin molding, and the mass productivity can be improved.

また熱交換器１ａは、単位素子２ａを方形に構成したために、一つの単位素子２ａを９０度回転しながら交互に積層するだけで熱交換器１ａが形成できるため、一つの金型を設けるだけでよく、製造コストを低減することができる。   In addition, since the heat exchanger 1a has a rectangular unit element 2a, the heat exchanger 1a can be formed by simply laminating one unit element 2a while rotating 90 degrees, so only one mold is provided. The manufacturing cost can be reduced.

また熱交換器１ａは、貫通穴９を方形の単位素子２ａの四隅に設けたことにより、単位素子２ａを誤って積層した時には、貫通穴９の周囲に設けた積層確認凸部１１と隣接する単位素子２ａの一部（第二の遮蔽リブ７ａａ）が干渉している状態が、熱交換器１ａ側面から容易に確認することができ、積み間違いを修正することによって生産工程の不良を低減することができ、量産性を向上することができる。   Further, the heat exchanger 1a is provided with the through holes 9 at the four corners of the rectangular unit element 2a, so that when the unit elements 2a are mistakenly stacked, the heat exchanger 1a is adjacent to the stacking confirmation convex portion 11 provided around the through hole 9. The state in which a part of the unit element 2a (second shielding rib 7aa) interferes can be easily confirmed from the side surface of the heat exchanger 1a, and the defect in the production process is reduced by correcting the stacking error. And mass productivity can be improved.

また熱交換器１ａは、単位素子２ａの第一の間隔リブ６ａ、第二の間隔リブ６ａａおよび第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａは何れかで連結し、且つ樹脂で構成されているため、第一の間隔リブ６ａに間隔リブ注入口１５を設け、第一の遮蔽リブ７ａに連結する位置に遮蔽リブ注入口１４ａを設けたことにより、成形工程２３において、伝熱板４を射出成形金型２４に挿入し、射出成形機にて伝熱板４と樹脂を一体成形するインサート射出成形工法で単位素子２ａを成形する際、間隔リブ注入口１５および遮蔽リブ注入口１４ａから溶融樹脂が注入することによって、第一の間隔リブ６ａ、第二の間隔リブ６ａａおよび第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａを有する単位素子２ａが一回の樹脂成形で一体に形成でき、量産性を向上することができる。またインサート射出成形工法を用いたことにより、一回の成形で伝熱板４と第一の間隔リブ６ａ、第二の間隔リブ６ａａと第一の遮蔽リブ７ａ、第二の遮蔽リブ７ａａが一体成形され、単位素子２ａを形成できることにより加工工程が少なくでき、更に量産性を向上することができ、また、部品点数が少なく、製造コストを低減することができる。   In the heat exchanger 1a, the first spacing rib 6a, the second spacing rib 6aa, the first shielding rib 7a, and the second shielding rib 7aa of the unit element 2a are connected to each other and are made of resin. Therefore, the spacing rib inlet 15 is provided in the first spacing rib 6a, and the shielding rib inlet 14a is provided at a position connected to the first shielding rib 7a. Is inserted into the injection mold 24, and when the unit element 2a is molded by the insert injection molding method in which the heat transfer plate 4 and the resin are integrally molded by an injection molding machine, the interval rib injection port 15 and the shielding rib injection port 14a are used. By injecting the molten resin, the unit elements 2a having the first spacing rib 6a, the second spacing rib 6aa, the first shielding rib 7a, and the second shielding rib 7aa are integrally formed by a single resin molding. And mass production It is possible to above. Further, by using the insert injection molding method, the heat transfer plate 4 and the first spacing rib 6a, the second spacing rib 6aa, the first shielding rib 7a, and the second shielding rib 7aa are integrated in one molding. By being molded and being able to form the unit element 2a, the number of processing steps can be reduced, the mass productivity can be further improved, the number of parts can be reduced, and the manufacturing cost can be reduced.

また間隔リブ注入口１５および遮蔽リブ注入口１４ａは、単位素子２ａを積層した際に隣接する単位素子２ａが干渉しないように逃がす手段として、第一の間隔リブ６ａおよび第一の遮蔽リブ７ａに段落としを備えているため、溶融樹脂が射出成形金型２４から注入される単位素子２ａの間隔リブ注入口１５および遮蔽リブ注入口１４ａにおいてバリが万一発生しても、単位素子２ａを積層した際に隣接する単位素子２ａ同士は逃がす手段によってバリを逃がすことにより干渉せず、隙間無く単位素子２ａを積層することができ、気流の漏れを防止することができる。   The spacing rib injection port 15 and the shielding rib injection port 14a are provided on the first spacing rib 6a and the first shielding rib 7a as means for releasing the adjacent unit elements 2a so as not to interfere when the unit elements 2a are stacked. Since the paragraph is provided, the unit element 2a is laminated even if burrs are generated in the interval rib injection port 15 and the shielding rib injection port 14a of the unit element 2a into which the molten resin is injected from the injection mold 24. Then, adjacent unit elements 2a do not interfere with each other by escaping burrs by means of escaping, so that the unit elements 2a can be stacked without any gap, and airflow leakage can be prevented.

また遮蔽リブ注入口１４ａの段落としは、第一の遮蔽リブ７ａに連結し、通風路５内に設けたことにより、溶融樹脂が射出成形金型２４から注入される単位素子２ａの注入口においてバリが万一発生しても、単位素子２ａを積層した際に隣接する単位素子２ａ同士は段落しによってバリを逃がすことにより干渉せず、更に前記バリは通風路５内に位置するため、隣接する単位素子との通風路５空間によってバリを逃がすことにより更に干渉せず、隙間無く単位素子２ａを積層することができ、気流の漏れを防止することができる。   Further, as the paragraph of the shielding rib injection port 14a, it is connected to the first shielding rib 7a and provided in the ventilation path 5, so that the molten resin is injected from the injection mold 24 at the injection port of the unit element 2a. Even if burrs are generated, the adjacent unit elements 2a when the unit elements 2a are stacked do not interfere with each other by escaping the burrs, and further, the burrs are located in the ventilation path 5 so that they are adjacent to each other. The unit element 2a can be stacked without any gap by allowing the burr to escape through the space of the ventilation path 5 with the unit element to be formed, and the leakage of airflow can be prevented.

また単位素子２ａを樹脂成形する射出成形金型２４にランナーレスにする手段を備えたことにより、樹脂成形時に廃材となるスプル・ランナー２６が出ず、樹脂材料費削減により製造コストを低減することができ、また省資源化することができる。   Further, by providing the injection mold 24 for resin molding the unit element 2a with a means for making runnerless, no sprue runner 26 which becomes a waste material at the time of resin molding is produced, and the manufacturing cost can be reduced by reducing the resin material cost. Can also save resources.

またランナーレスにする手段として、ホットランナーを使用したことにより、射出成形金型２４のランナー・ゲート部をヒータ２５で加熱制御して常に流動化状態に保てるため、樹脂成形時に廃材となるスプル・ランナー２６が出ず、樹脂材料費削減により製造コストを低減することができ、また省資源化することができる。また成形品の単位素子２ａのみを射出成形金型２４から連続的に取り出せるので成形サイクルの短縮ができ、量産性を向上することができる。   In addition, as a means to make runnerless, by using a hot runner, the runner gate part of the injection mold 24 is heated and controlled by the heater 25 so that it is always in a fluidized state. The runner 26 does not come out, the manufacturing cost can be reduced by reducing the resin material cost, and the resource can be saved. Further, since only the unit element 2a of the molded product can be continuously taken out from the injection mold 24, the molding cycle can be shortened and the mass productivity can be improved.

またオープンゲート式のホットランナーを使用したことにより、射出成形金型２４のランナー・ゲート部をヒータ２５で加熱制御して常に流動化状態に保てるため、樹脂成形時に廃材となるスプル・ランナー２６が出ず、樹脂材料費削減により製造コストを低減することができ、また省資源化することができる。また成形品の単位素子２ａのみを射出成形金型２４から連続的に取り出せるので成形サイクルの短縮ができ、量産性を向上することができる。   In addition, the use of an open gate type hot runner allows the runner gate portion of the injection mold 24 to be heated and controlled by the heater 25 so that it is always in a fluidized state. In addition, the manufacturing cost can be reduced and the resource can be saved by reducing the resin material cost. Further, since only the unit element 2a of the molded product can be continuously taken out from the injection mold 24, the molding cycle can be shortened and the mass productivity can be improved.

またゲート開閉機能を有するバルブゲート式のホットランナーを使用したことにより、溶融樹脂が射出成形金型２４から注入される単位素子２ａの間隔リブ注入口１５および遮蔽リブ注入口１４ａにおいてバリができないため、単位素子２ａを積層した際に隣接する単位素子２ａ同士がバリによって干渉することがなく、隙間無く単位素子２ａを積層することができ、気流の漏れを防止することができる。   Further, since a valve gate type hot runner having a gate opening / closing function is used, burrs cannot be formed at the interval rib injection port 15 and the shielding rib injection port 14a of the unit element 2a into which the molten resin is injected from the injection mold 24. When the unit elements 2a are stacked, the adjacent unit elements 2a do not interfere with each other by the burr, and the unit elements 2a can be stacked without a gap, thereby preventing airflow leakage.

図１６（ａ）、１６（ｂ）、１６（ｃ）に示すように、第一の間隔リブ６ａと第二の間隔リブ６ａａは単位素子２ａを交互に９０度回転しながら積層した時に、隣接する第一の間隔リブ６ａと第二の間隔リブ６ａａが重なり合うように形成され、伝熱板４を一定の間隔に保持する働がある。本実施の形態では、第一の間隔リブ６ａおよび第二の間隔リブ６ａａの凸高さを１ｍｍとしたので、伝熱板４は２ｍｍ毎に積層される。   As shown in FIGS. 16 (a), 16 (b), and 16 (c), the first spacing rib 6a and the second spacing rib 6aa are adjacent to each other when the unit elements 2a are stacked while being alternately rotated by 90 degrees. The first spacing rib 6a and the second spacing rib 6aa are formed so as to overlap each other, and have a function of holding the heat transfer plate 4 at a constant spacing. In the present embodiment, since the convex height of the first spacing rib 6a and the second spacing rib 6aa is 1 mm, the heat transfer plate 4 is laminated every 2 mm.

図１６（ａ）、１６（ｂ）、１６（ｃ）に示すように、間隔リブ凸部２９と間隔リブ凹部３１は単位素子２ｂを交互に９０度回転しながら正しく積層した時には、隣接する間隔リブ凸部２９の凸部と間隔リブ凹部３１の凹部が嵌合するよう形成される。熱交換器１ｂは第一の間隔リブ６ａおよび第二の間隔リブ６ａａに設けた間隔リブ凸部２９と間隔リブ凹部３１の嵌合により、単位素子２ｂ同士が互いに固定化され、且つ単位素子２ｂを積層する際に発生する位置ずれを防止する。熱交換器１ｂの伝熱板４を一定の間隔に保持する構成は、図１６（ｃ）に示すように隣接する第一の間隔リブ６ａおよび第二の間隔リブ６ａａ同士が重なり合うことにより行われ、間隔リブ凸部２９の凸部と間隔リブ凹部３１の凹部の嵌合も伝熱板４を一定の間隔に保持する。この明細書では、金型の製造精度と樹脂成形の精度を考慮して、第一の間隔リブ６ａおよび第二の間隔リブ６ａａは必ず重なり合うようにし、間隔リブ凸部２９と間隔リブ凹部３１の嵌合は、高さ方向に０．１ｍｍの積層逃がし部２０ｅを設けた。なお０．１ｍｍの高さ方向の積層逃がし部２０ｅを設けたが、単位素子２ｂを正しく積層した時に、熱交換器１ｂの伝熱板４が一定の間隔に保たれれば良く、熱交換器の設計や製造精度により適宜決定する。   As shown in FIGS. 16 (a), 16 (b), and 16 (c), the interval rib protrusion 29 and the interval rib recess 31 are adjacent to each other when the unit elements 2b are correctly stacked while being rotated 90 degrees alternately. The convex part of the rib convex part 29 and the concave part of the space | interval rib recessed part 31 are formed so that it may fit. In the heat exchanger 1b, the unit elements 2b are fixed to each other by the fitting of the spacing rib protrusions 29 and the spacing rib recesses 31 provided on the first spacing rib 6a and the second spacing rib 6aa, and the unit elements 2b This prevents the positional deviation that occurs when the layers are stacked. The configuration in which the heat transfer plate 4 of the heat exchanger 1b is held at a constant interval is performed by overlapping the adjacent first interval ribs 6a and second interval ribs 6aa as shown in FIG. 16 (c). The fitting of the convex portions of the spacing rib convex portions 29 and the concave portions of the spacing rib concave portions 31 also holds the heat transfer plate 4 at a constant interval. In this specification, in consideration of the manufacturing accuracy of the mold and the accuracy of resin molding, the first spacing rib 6a and the second spacing rib 6aa are necessarily overlapped, and the spacing rib convex portion 29 and the spacing rib concave portion 31 are formed. For fitting, a stacking relief portion 20e of 0.1 mm was provided in the height direction. Although the stacking relief portion 20e in the height direction of 0.1 mm is provided, it is sufficient if the heat transfer plate 4 of the heat exchanger 1b is kept at a constant interval when the unit elements 2b are correctly stacked. It is determined appropriately according to the design and manufacturing accuracy.

図１７（ａ）、１７（ｂ）、１７（ｃ）に示すように、単位素子２ｂを交互に９０度回転せず、誤って積層した時には、間隔リブ凸部２９の凸部は隣接する第二の遮蔽リブ７ａａと干渉し、隣接する単位素子２ｂ同士が嵌合できず、熱交換器１ｂの側面から確認すると単位素子２ｂ同士に隙間があり、容易に単位素子２ｂの積み間違いを確認することができる構成となっている。   As shown in FIGS. 17 (a), 17 (b), and 17 (c), when the unit elements 2b are not rotated alternately by 90 degrees and are stacked by mistake, the protrusions of the spacing rib protrusions 29 are adjacent to each other. Interfering with the second shielding rib 7aa, the adjacent unit elements 2b cannot be fitted to each other, and when confirmed from the side surface of the heat exchanger 1b, there is a gap between the unit elements 2b, and the unit element 2b is easily confirmed to be stacked incorrectly. It has a configuration that can.

なお間隔リブ凸部２９および間隔リブ凹部３１は単位素子２ｂの第一の間隔リブ６ａおよび第二の間隔リブ６ａａに設けたが、単位素子を正しく積層した時には隣接する単位素子の凹部と凸部が嵌合し、誤って積層した時には凸部と隣接する単位素子の一部が干渉する構造であれば、その他の構成の熱交換器を用いても同様の作用効果を得ることができる。   The spacing rib convex portion 29 and the spacing rib concave portion 31 are provided in the first spacing rib 6a and the second spacing rib 6aa of the unit element 2b. However, when the unit elements are correctly stacked, the concave portion and the convex portion of the adjacent unit elements are provided. As long as they are fitted and mistakenly stacked, a part of the unit element adjacent to the convex part interferes, and the same effect can be obtained even if a heat exchanger having another configuration is used.

図１８（ａ）、１８（ｂ）、１８（ｃ）に示すように、貫通穴一部凹部３２と貫通穴一部凸部３０は単位素子２ｂを交互に９０度回転しながら正しく積層した時には、隣接する貫通穴一部凹部３２の凹部と貫通穴一部凸部３０の凸部が嵌合するよう形成される。熱交換器１ｂは方形の単位素子２ｂの対角する２箇所に設けた貫通穴一部凹部３２と貫通穴一部凸部３０の嵌合により、単位素子２ｂ同士が互いに固定化され、且つ単位素子２ｂを積層する際に発生する位置ずれを防止する。熱交換器１ｂの四隅における気流の遮蔽は、図１８（ｃ）に示すように隣接する第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａ同士が重なり合うことにより行われ、貫通穴一部凹部３２の凹部と貫通穴一部凸部３０の凸部の嵌合も気流の遮蔽を行う。この明細書では、金型の製造精度と樹脂成形の精度を考慮して、第一の遮蔽リブ７ａおよび第二の遮蔽リブ７ａａは必ず重なり合うようにし、貫通穴一部凹部３２と貫通穴一部凸部３０の嵌合は、気流が漏れない程度に高さ方向に０．１ｍｍの積層逃がし部２０ｆを設けた。なお０．１ｍｍの高さ方向の積層逃がし部２０ｆを設けたが、単位素子２ｂを正しく積層した時には、熱交換器１ｂの四隅における気流の遮蔽と単位素子２ｂ同士の嵌合ができれば良く、熱交換器の設計や製造精度により適宜決定する。   As shown in FIGS. 18 (a), 18 (b) and 18 (c), when the through-hole partial recesses 32 and the through-hole partial protrusions 30 are correctly stacked while alternately rotating the unit elements 2b by 90 degrees. The concave portions of the adjacent through hole partial concave portions 32 and the convex portions of the through hole partial convex portions 30 are formed to be fitted. In the heat exchanger 1b, the unit elements 2b are fixed to each other by fitting the through-hole partial concave portions 32 and the through-hole partial convex portions 30 provided at two diagonal positions of the rectangular unit element 2b. Misalignment that occurs when the elements 2b are stacked is prevented. Airflow shielding at the four corners of the heat exchanger 1b is performed by overlapping the adjacent first and second shielding ribs 7a and 7aa as shown in FIG. The fitting of the concave portion and the convex portion of the through-hole partial convex portion 30 also shields the airflow. In this specification, in consideration of mold manufacturing accuracy and resin molding accuracy, the first shielding rib 7a and the second shielding rib 7aa are always overlapped, and the through-hole partial recess 32 and the through-hole partial The fitting of the convex part 30 provided the laminated relief part 20f of 0.1 mm in the height direction so that the airflow did not leak. Although the stacking relief part 20f in the height direction of 0.1 mm is provided, when the unit elements 2b are stacked correctly, it is only necessary to shield the air flow at the four corners of the heat exchanger 1b and fit the unit elements 2b to each other. It is determined appropriately according to the design and manufacturing accuracy of the exchanger.

図１９（ａ）、１９（ｂ）、１９（ｃ）に示すように、単位素子２ｂを交互に９０度回転せず、誤って積層した時には、貫通穴一部凸部３０の凸部は隣接する第二の遮蔽リブ７ａａと干渉し、隣接する単位素子２ｂ同士が嵌合できず、熱交換器１ｂの側面から確認すると単位素子２ｂ同士に隙間があり、容易に単位素子２ｂの積み間違いを確認することができる構成となっている。   As shown in FIGS. 19 (a), 19 (b), and 19 (c), when the unit elements 2b are not alternately rotated by 90 degrees and are stacked incorrectly, the protrusions of the through-hole partial protrusions 30 are adjacent to each other. The adjacent unit elements 2b cannot be fitted to each other, and there is a gap between the unit elements 2b when confirmed from the side surface of the heat exchanger 1b. The configuration can be confirmed.

なお貫通穴一部凹部３２および貫通穴一部凸部３０は貫通穴９の４箇所の穴の一部として、方形の単位素子２ｂの対角する２箇所に設けた。例えば、貫通穴９の４箇所に貫通穴一部凹部３２の凹部と貫通穴一部凸部３０の凸部を設けた場合、誤って単位素子２ａを積層した時にも隣接する単位素子２ａの貫通穴一部凹部３２の凹部と貫通穴一部凸部３０の凸部が嵌合し、単位素子２ａの積み間違いが分からないため、貫通穴一部凹部３２および貫通穴一部凸部３０は貫通穴９の４箇所の穴の一部に備えた。この明細書では貫通穴９の４箇所の穴の一部として、方形の単位素子２ｂの対角する２箇所に設けが、貫通穴９の穴の一部とは、単位素子を正しく積層した時には隣接する単位素子の凹部と凸部が嵌合し、誤って積層した時には凸部と隣接する単位素子の一部が干渉する構造であれば、その他の構成の熱交換器を用いても同様の作用効果を得ることができる。   In addition, the through-hole partial recessed part 32 and the through-hole partial convex part 30 were provided in two places diagonally of the square unit element 2b as a part of four holes of the through-hole 9. FIG. For example, when the concave portion of the through-hole partial concave portion 32 and the convex portion of the through-hole partial convex portion 30 are provided at four locations of the through-hole 9, even when the unit elements 2a are mistakenly stacked, the adjacent unit element 2a penetrates. Since the concave portion of the hole partial concave portion 32 and the convex portion of the through hole partial convex portion 30 are fitted and the unit element 2a is not stacked correctly, the through hole partial concave portion 32 and the through hole partial convex portion 30 pass through. It prepared in a part of four holes of the hole 9. FIG. In this specification, as part of the four holes of the through-hole 9, the rectangular unit element 2 b is provided at two opposite corners. The part of the hole of the through-hole 9 means that the unit elements are correctly stacked. As long as the concave and convex portions of the adjacent unit elements are fitted together and a part of the unit elements adjacent to the convex portion interferes when they are mistakenly stacked, the same applies even if a heat exchanger of other configuration is used. An effect can be obtained.

熱交換器１ｂは単位素子２ｂを積層した時に隣接する単位素子２ｂが干渉しないように逃がす手段を備え、逃がす手段として、第一の遮蔽リブ７ａに連結し、通風路５の外側に遮蔽リブ注入口１４ｂの段落としを設けた構成である。   The heat exchanger 1b is provided with a means for allowing the adjacent unit elements 2b to interfere with each other when the unit elements 2b are stacked, and is connected to the first shielding rib 7a as a means for escape, and the shielding rib is provided outside the ventilation path 5. It is the structure which provided as the paragraph of the entrance 14b.

図１４に示すように、遮蔽リブ注入口１４ｂは通風路５の外側に段落としを設けたことにより、溶融樹脂が金型から注入される遮蔽リブ注入口１４ｂにおいてバリが万一発生しても、単位素子２ｂを積層した際に隣接する単位素２ｂ同士は段落しによってバリを逃がすことにより干渉せず、更に前記バリは通風路５の外側に位置するため、隣接する単位素子２ｂとの空間を大きくでき、バリを逃がすことにより更に干渉せず、隙間無く単位素子２ｂを積層することができる。   As shown in FIG. 14, the shielding rib injection port 14b is provided with a paragraph outside the ventilation path 5, so that even if a burr occurs in the shielding rib injection port 14b through which molten resin is injected from the mold. When the unit elements 2b are stacked, the adjacent unit elements 2b do not interfere with each other by escaping burrs by breaking, and the burrs are located outside the ventilation path 5, so that the space between the adjacent unit elements 2b The unit element 2b can be stacked without a gap without causing further interference by releasing the burr.

なお、遮蔽リブ注入口１４ｂの段落しは第一の遮蔽リブ７ａに連結するように設けたが、溶融樹脂を注入する注入口は、第一の遮蔽リブ７ａの少なくとも何れかに連結し、通風路５の外側に設け、バリを逃がすように段落しにする構成であれば良く、その他の構成を用いても同様の作用効果を得ることができる。   Although the shielding rib inlet 14b is connected to the first shielding rib 7a, the inlet for injecting the molten resin is connected to at least one of the first shielding ribs 7a for ventilation. Any structure may be used as long as it is provided on the outside of the path 5 so that the burrs are escaped, and similar effects can be obtained by using other structures.

上記構成により、熱交換器１ｂは、単位素子２ｂを積層した際に積み間違いが分かる手段として、第一の間隔リブ６ａ、第二の間隔リブ６ａａに間隔リブ凸部２９と間隔リブ凹部３１を備えたことにより、単位素子２ｂを正しく積層した時には隣接する単位素子２ｂの間隔リブ凸部２９の凸部と間隔リブ凹部３１の凹部が嵌合し、誤って積層した時には間隔リブ凸部２９の凸部と隣接する単位素子２ｂの一部（第二の遮蔽リブ７ａａ）が干渉するため、単位素子２ｂの積み間違いを容易に確認することができ、積み間違いを修正することによって生産工程の不良を低減することができ、量産性を向上することができる。また単位素子２ｂの積み間違いに起因する密封性の低下を防止することができ、気流の漏れを防止することができる。また間隔リブ凸部２９の凸部と間隔リブ凹部３１の凹部は単位素子２ｂを積層した際に凹部と凸部が嵌合することにより、単位素子２ｂ同士が互いに固定するため、単位素子２ｂのずれに起因する密封性の低下を防止することができ、気流の漏れを防止することができ、また前記嵌合構造が単位素子２ｂを積層する際に発生する位置ずれを防止することにより、量産性を向上することができる。   With the above configuration, the heat exchanger 1b includes the first ribs 6a and the second ribs 6aa with the rib rib protrusions 29 and the rib rib recesses 31 as means for understanding the stacking error when the unit elements 2b are stacked. As a result, when the unit elements 2b are correctly stacked, the protrusions of the interval rib protrusions 29 of the adjacent unit elements 2b and the recesses of the interval rib recesses 31 are fitted. Since a part (second shielding rib 7aa) of the unit element 2b adjacent to the convex part interferes, it is possible to easily check the stacking error of the unit elements 2b, and to correct the stacking error, thereby producing a defective production process. Can be reduced, and mass productivity can be improved. In addition, it is possible to prevent the sealing performance from being lowered due to erroneous stacking of the unit elements 2b, and to prevent airflow leakage. Further, since the convex portions of the spacing rib convex portion 29 and the concave portion of the spacing rib concave portion 31 are fixed to each other by fitting the concave portion and the convex portion when the unit elements 2b are stacked, the unit elements 2b are fixed to each other. Decrease in sealing performance due to deviation can be prevented, leakage of airflow can be prevented, and the fitting structure can prevent mass misalignment that occurs when the unit elements 2b are stacked. Can be improved.

また熱交換器１ｂは、単位素子２ｂに貫通穴９を備え、この貫通穴９の一部の周囲として、方形の単位素子２ｂの対角する２箇所に貫通穴一部凹部３２および貫通穴一部凸部３０を備えたことにより、単位素子２ｂを正しく積層した時には隣接する単位素子２ｂの貫通穴一部凹部３２と貫通穴一部凸部３０が嵌合し、誤って積層した時には貫通穴一部凸部３０と隣接する単位素子２ｂの一部（第二の遮蔽リブ７ａａ）が干渉するため、単位素子２ｂの積み間違いを容易に確認することができ、積み間違いを修正することによって生産工程の不良を低減することができ、量産性を向上することができる。また単位素子２ｂの積み間違いに起因する密封性の低下を防止することができ、気流の漏れを防止することができる。また単位素子２ｂを積層した際に貫通穴一部凹部３２と貫通穴一部凸部３０が嵌合することにより、単位素子２ｂ同士が互いに固定するため、単位素子２ｂのずれに起因する密封性の低下を防止することができ、気流の漏れを防止することができ、また前記嵌合構造が単位素子２ｂを積層する際に発生する位置ずれを防止することにより、量産性を向上することができる。   Further, the heat exchanger 1b includes a through hole 9 in the unit element 2b, and a part of the through hole partial recess 32 and the through hole are provided at two positions opposite to the rectangular unit element 2b as a periphery of a part of the through hole 9. When the unit elements 2b are correctly stacked, the through-hole partial recesses 32 and the through-hole partial protrusions 30 of the adjacent unit elements 2b are fitted together, and when the unit elements 2b are stacked incorrectly, the through-holes are provided. Since a part of the convex part 30 and a part of the adjacent unit element 2b (second shielding rib 7aa) interfere with each other, it is possible to easily check the stacking error of the unit element 2b and to produce by correcting the stacking error. Process defects can be reduced, and mass productivity can be improved. In addition, it is possible to prevent the sealing performance from being lowered due to erroneous stacking of the unit elements 2b, and to prevent airflow leakage. Further, when the unit elements 2b are stacked, the through-hole partial concave portions 32 and the through-hole partial convex portions 30 are fitted to each other so that the unit elements 2b are fixed to each other. Can be prevented, the airflow can be prevented from leaking, and the fitting structure can improve the mass productivity by preventing the positional deviation that occurs when the unit elements 2b are stacked. it can.

また遮蔽リブ注入口１４ｂの段落としは、第一の遮蔽リブ７ａに連結し、通風路５の外側に設けたことにより、溶融樹脂が射出成形金型２４から注入される単位素子２ｂの注入口においてバリが万一発生しても、単位素子２ｂを積層した際に隣接する単位素子２ｂ同士は段落しによってバリを逃がすことにより干渉せず、更に前記バリは通風路５の外側に位置するため、隣接する単位素子２ｂとの空間を大きくでき、バリを逃がすことにより更に干渉せず、隙間無く単位素子２ｂを積層することができ、気流の漏れを防止することができる。   Further, as the paragraph of the shielding rib injection port 14b, the injection port of the unit element 2b into which the molten resin is injected from the injection mold 24 by being connected to the first shielding rib 7a and provided outside the ventilation path 5 is provided. Even if burrs are generated in the case, the unit elements 2b adjacent to each other when the unit elements 2b are stacked do not interfere with each other by escaping the burrs, and further, the burrs are located outside the ventilation path 5. The space between the adjacent unit elements 2b can be increased, and the unit elements 2b can be stacked without any gap without further interference by escaping burrs, thereby preventing airflow leakage.
