Description

本発明は、熱交換器の外周面と空調ケースの内周面との間の気密を保持する熱交換器のシール構造に関する。   The present invention relates to a heat exchanger sealing structure that maintains an airtightness between an outer peripheral surface of a heat exchanger and an inner peripheral surface of an air conditioning case.

この種の従来の熱交換器のシール構造としては、図６に示す特許文献１に開示されたものがある。図６において、自動車用空気調和装置１００は、内部に送風路１０１ａが形成された空調ケース１０１と、この空調ケース１０１内の送風路１０１ａに配置された熱交換器１０２とを備えている。この熱交換器１０２の全外周と空調ケース１０１の内周面との間には、断熱材のシール部材１０３が介在されている。   As this type of conventional heat exchanger seal structure, there is one disclosed in Patent Document 1 shown in FIG. In FIG. 6, the automobile air conditioner 100 includes an air conditioning case 101 in which an air passage 101 a is formed, and a heat exchanger 102 disposed in the air passage 101 a in the air conditioning case 101. A heat insulating seal member 103 is interposed between the entire outer periphery of the heat exchanger 102 and the inner peripheral surface of the air conditioning case 101.

このシール部材１０３は、熱交換器１０２の外周面を被うシール本体部１０３ａと、外周面の両側面の一部を挟む込むように延設された一対の挟持部１０３ｂ，１０３ｂとからコ字形状に形成されている。コ字形状に形成することによって、断熱機能やシール機能や防振機能の他に、熱交換器１０２の位置ずれ防止機能を具備する。   The seal member 103 is formed from a seal main body portion 103a covering the outer peripheral surface of the heat exchanger 102 and a pair of sandwiching portions 103b and 103b extending so as to sandwich part of both side surfaces of the outer peripheral surface. It is formed into a shape. By forming the U-shape, in addition to the heat insulating function, the sealing function, and the vibration isolating function, the heat exchanger 102 is provided with a function for preventing the positional deviation.

尚、熱交換器の外周をコ字形状で被うシール部材の構成は、特許文献２にも開示されている。

JP-A-9-169210 JP 2003-89313 A

しかしながら、従来の熱交換器１０２のシール構造では、シール部材１０３をコ字形状に形成する必要があるため、シール部材１０３が大型化し、高コストであるという問題がある。   However, in the conventional seal structure of the heat exchanger 102, since the seal member 103 needs to be formed in a U-shape, there is a problem that the seal member 103 is large and expensive.

そこで、本発明は、シール部材を小型化でき、低コストにできる熱交換器のシール構造を提供することを目的とする。   Then, an object of this invention is to provide the sealing structure of the heat exchanger which can make a sealing member small and can be made low-cost.

上記目的を達成する請求項１の発明は、空調ケース内に配置された熱交換器の外周面と、前記空調ケースの内周面との間にシール部材が狭持された熱交換器のシール構造において、前記外周面と前記内周面との互いに対向する少なくとも２面に段差部が設けられ、前記シール部材には、これら双方の段差部にそれぞれに嵌合可能に形成された嵌合突起部が設けられたことを特徴とする。   The invention according to claim 1, which achieves the above object, provides a seal for a heat exchanger in which a seal member is sandwiched between an outer peripheral surface of a heat exchanger disposed in an air conditioning case and an inner peripheral surface of the air conditioning case. In the structure, step portions are provided on at least two surfaces of the outer peripheral surface and the inner peripheral surface facing each other, and the sealing member has fitting protrusions formed so as to be fitted to both of the step portions. A part is provided.

請求項２の発明は、請求項１記載の熱交換器のシール構造であって、前記熱交換器の外周面には段差部としての凹部が一箇所に設けられ、前記空調ケースの内周面には段差部としての凸部が二箇所に設けられ、前記シール部材には前記凹部に嵌合する内周側嵌合突起部と二箇所の前記凸部の内側又は外側に嵌合する外周側嵌合突起部が二箇所に設けられたことを特徴とする。   The invention of claim 2 is the heat exchanger seal structure according to claim 1, wherein the outer peripheral surface of the heat exchanger is provided with a recess as a step portion at one location, and the inner peripheral surface of the air conditioning case Are provided with two convex portions as stepped portions, and the sealing member has an inner peripheral side fitting projection that fits into the concave portion and two outer peripheral sides that fit inside or outside the convex portion. The fitting protrusion is provided at two places.

請求項３の発明は、請求項１記載の熱交換器のシール構造であって、前記熱交換器の外周面には段差部としての凹部が一箇所に設けられ、前記空調ケースの内周面には段差部としての凸部が一箇所に設けられ、前記シール部材には前記凹部に嵌合する内周側嵌合突起部と一箇所の前記凸部を外側から挟むようにして嵌合する外周側嵌合突起部が二箇所に設けられたことを特徴とする。   The invention of claim 3 is the seal structure of the heat exchanger according to claim 1, wherein the outer peripheral surface of the heat exchanger is provided with a recess as a step portion at one location, and the inner peripheral surface of the air conditioning case Is provided with a convex portion as a stepped portion, and the sealing member is fitted with an inner peripheral side protruding projection that fits into the concave portion and an outer peripheral side that is fitted so as to sandwich the convex portion at one location from the outside. The fitting protrusion is provided at two places.

請求項４の発明は、請求項１〜請求項３のいずれか１項記載の熱交換器のシール構造であって、前記シール部材は、環状に連続した形態であることを特徴とする。   A fourth aspect of the present invention is the heat exchanger seal structure according to any one of the first to third aspects, wherein the seal member has an annular continuous form.

請求項１の発明によれば、シール部材は、エバポレータと空調ケースの間にシール部材が密着状態で介在されるため、シール部材は断熱機能やシール機能や防振機能を有する。エバポレータ及び空調ケースの段差部とシール部材の嵌合突起部による嵌合構造によって、位置ずれ防止機能を有する。このような各種機能を具備するシール部材は、熱交換器側と空調ケース側に嵌合突起部をそれぞれ設けるだけの幅寸法を有すれば足りるため、シール部材を小型化でき、低コストにできる。又、外周にシール部材を装着した熱交換器をシール部材の弾性圧縮変形を利用して空調ケース内に嵌合することによって配置できるため、熱交換器の設置作業性が良い。   According to the first aspect of the present invention, since the sealing member is interposed between the evaporator and the air conditioning case in a close contact state, the sealing member has a heat insulating function, a sealing function, and a vibration isolating function. A misalignment prevention function is provided by the fitting structure of the step portion of the evaporator and the air conditioning case and the fitting protrusion of the seal member. Since the sealing member having such various functions only needs to have width dimensions sufficient to provide the fitting protrusions on the heat exchanger side and the air conditioning case side, the sealing member can be reduced in size and cost can be reduced. . Further, since the heat exchanger having the seal member on the outer periphery can be disposed by fitting it in the air conditioning case using the elastic compression deformation of the seal member, the heat exchanger can be installed easily.

請求項４の発明によれば、請求項１の発明の効果に加え、切れ目があるシール部材の場合にはその切れ目の箇所でシール漏れの恐れがあるが、切れ目の箇所でのシール漏れが発生することはない。   According to the invention of claim 4, in addition to the effect of the invention of claim 1, in the case of a seal member with a cut, there is a risk of seal leakage at the cut part, but a seal leak at the cut part occurs. Never do.

図１に示すように、自動車用空気調和装置１は、内部に送風路２ａが形成された空調ケース２と、この空調ケース２内の送風路２ａを横切るように配置された熱交換器であるエバポレータ３とを備えている。   As shown in FIG. 1, an automotive air conditioner 1 is an air conditioner case 2 in which an air passage 2 a is formed, and a heat exchanger disposed so as to cross the air passage 2 a in the air conditioner case 2. And an evaporator 3.

エバポレータ３は、積層配置された複数のチューブ体４と、この積層方向の両端部に配置された一対のエンドプレート５と、隣接するチューブ体４，４間等の隙間に配置された複数のフィン６と、積層方向の一端に配置されつつ、チューブ体４に連結され、膨張弁（図示せず）を内包するパイプ接続ブロック７とから構成されている。   The evaporator 3 includes a plurality of tube bodies 4 arranged in a stack, a pair of end plates 5 arranged at both ends in the stacking direction, and a plurality of fins arranged in a gap between adjacent tube bodies 4 and 4. 6 and a pipe connection block 7 connected to the tube body 4 and including an expansion valve (not shown) while being disposed at one end in the stacking direction.

各チューブ体４は、互いに突き合わされた状態で接合された一対のチューブシート４ａ，４ａから構成されている。各チューブ体４の内部には、図２及び図３に示すように、その一端側に入口タンク室１０及び出口タンク室１１が、他端側に折り返しタンク室１２が、入口タンク室１０と折り返しタンク室１２間を連通する冷媒往通路１３が、出口タンク室１１と折り返しタンク室１２間を連通する冷媒復通路１４がそれぞれ形成されている。又、各チューブ体４には、隣接する入口タンク室１０同士、出口タンク室１１同士、及び、隣接する折り返しタンク室１２同士を連通する連通孔１５ａ，１５ｂ，１５ｃがそれぞれ形成されている。   Each tube body 4 is composed of a pair of tube sheets 4a and 4a joined in a state of being butted against each other. As shown in FIGS. 2 and 3, each tube body 4 has an inlet tank chamber 10 and an outlet tank chamber 11 on one end side, a folded tank chamber 12 on the other end side, and folded with the inlet tank chamber 10. A refrigerant forward passage 13 that communicates between the tank chambers 12 and a refrigerant return passage 14 that communicates between the outlet tank chamber 11 and the folded tank chamber 12 are formed. Each tube body 4 is formed with communication holes 15a, 15b, and 15c for communicating adjacent inlet tank chambers 10, outlet tank chambers 11, and adjacent folded tank chambers 12 respectively.

パイプ接続ブロック７は、一端側端部のチューブ体４の入口タンク室１０と出口タンク室１１にそれぞれ連通するパイプ中継室（図示せず）をそれぞれ有する。パイプ接続ブロック７には、冷凍サイクルの入口パイプ（図示せず）と出口パイプ（図示せず）がそれぞれ接続される。入口タイプ（図示せず）及び出口パイプ（図示せず）はパイプ接続ブロック７を介して入口タンク室（１０）と出口タンク室（１１）にそれぞれ連通される。   The pipe connection block 7 has pipe relay chambers (not shown) respectively communicating with the inlet tank chamber 10 and the outlet tank chamber 11 of the tube body 4 at one end portion. The pipe connection block 7 is connected to an inlet pipe (not shown) and an outlet pipe (not shown) of the refrigeration cycle. An inlet type (not shown) and an outlet pipe (not shown) are communicated with an inlet tank chamber (10) and an outlet tank chamber (11) via a pipe connection block 7, respectively.

入口パイプ（図示せず）からエバポレータ３内に流入された冷媒は、各チューブ体４の入口タンク室１０、冷媒往通路１３、折り返しタンク室１２、冷媒復通路１４の順に流れて出口タンク室１１に戻り、出口パイプ（図示せず）からエバポレータ３外に流出される。   The refrigerant that has flowed into the evaporator 3 from the inlet pipe (not shown) flows in the order of the inlet tank chamber 10, the refrigerant forward passage 13, the return tank chamber 12, and the refrigerant return passage 14 of each tube body 4. The flow returns to the outside of the evaporator 3 through an outlet pipe (not shown).

このように構成されたエバポレータ３は、その外周面と空調ケース２の内周面との間がシール構造によってシールされている。以下、そのシール構造を詳しく説明する。   The evaporator 3 configured in this way is sealed between its outer peripheral surface and the inner peripheral surface of the air conditioning case 2 by a sealing structure. Hereinafter, the seal structure will be described in detail.

エバポレータ３の外周面は、図１に示すように、左右位置の各チューブ体４の外周面と上下位置のエンドプレート５の外周面との４面から構成されている。図２及び図３に示すように、チューブ体４の外周面には段差部である凹部２０が一箇所に設けられている。エンドプレート５の外周面は、それぞれフラット面に形成されている。   As shown in FIG. 1, the outer peripheral surface of the evaporator 3 is composed of four surfaces: an outer peripheral surface of each tube body 4 at the left and right positions and an outer peripheral surface of the end plate 5 at the upper and lower positions. As shown in FIG. 2 and FIG. 3, the outer peripheral surface of the tube body 4 is provided with a recess 20 that is a stepped portion at one location. The outer peripheral surface of the end plate 5 is formed as a flat surface.

空調ケース２の内周面は、図１に示すように、左右位置の左右内周面と上下位置の上下内周面との４面から構成されている。図２及び図３に示すように、左右内周面には段差部である凸部２１，２１が二箇所に設けられている。上下内周面は、それぞれフラット面に形成されている。   As shown in FIG. 1, the inner peripheral surface of the air conditioning case 2 is composed of four surfaces, that is, left and right inner peripheral surfaces at the left and right positions and upper and lower inner peripheral surfaces at the upper and lower positions. As shown in FIGS. 2 and 3, convex portions 21 and 21 that are stepped portions are provided at two locations on the left and right inner peripheral surfaces. The upper and lower inner peripheral surfaces are each formed as a flat surface.

シール部材２２は、弾性に富むゴム材などで形成されている。シール部材２２は、左右の縦枠２２ａ，２２ｂと上下の横枠２２ｃ，２２ｄとから方形枠体で、且つ、環状に連続した形態を有する。   The seal member 22 is formed of a rubber material that is rich in elasticity. The seal member 22 is a rectangular frame body formed from left and right vertical frames 22a and 22b and upper and lower horizontal frames 22c and 22d, and has an annularly continuous form.

左右の各縦枠２２ａ，２２ｂの内面には、一箇所に内周側嵌合突起部２３が長手方向に沿って突設されている。左右の各縦枠２２ｃ，２２ｄの外面には、二箇所に外周側嵌合突起部２４，２４が長手方向に沿って突設されている。そして、シール部材２２の左右の縦枠２２ａ，２２ｂは、その内周側嵌合突起部２３がエバポレータの凹部２０に、その二箇所の外周側嵌合突起部２４，２４がエバポレータの二箇所の凸部２１，２１の内側にそれぞれ嵌合された状態で密着されている。シール部材２２の上下の横枠２２ｃ，２２ｄは、その内外面がエバポレータ３と空調ケース２のフラット面に単に密着されている。   On the inner surface of each of the left and right vertical frames 22a and 22b, an inner peripheral side fitting projection 23 is provided at one location along the longitudinal direction. On the outer surface of each of the left and right vertical frames 22c and 22d, outer peripheral side fitting projections 24 and 24 are provided in two locations along the longitudinal direction. The left and right vertical frames 22a, 22b of the seal member 22 have inner fitting projections 23 in the evaporator recess 20, and two outer fitting projections 24, 24 in the evaporator. The protrusions 21 and 21 are in close contact with each other while being fitted inside. The upper and lower horizontal frames 22 c and 22 d of the sealing member 22 are simply in close contact with the flat surfaces of the evaporator 3 and the air conditioning case 2.

又、シール部材２２には、図４に示すように、パイプ接続ブロック７の外周を囲む筒部２２ｅが一体に設けられている。この筒部２２ｅは、その先端に折り返し鍔部２２ｆを有し、この折り返し鍔部２２ｆによって空調ケース２の内面との間がシールされている。   Further, as shown in FIG. 4, the seal member 22 is integrally provided with a cylindrical portion 22 e surrounding the outer periphery of the pipe connection block 7. The cylindrical portion 22e has a folded flange portion 22f at the tip thereof, and the space between the inner surface of the air conditioning case 2 is sealed by the folded flange portion 22f.

上記構成において、空調ケース２内の送風路２ａに上流側から送風が送られてくると、その送風はエバポレータ３の隣接するチューブ体４の隙間を通り、この通過過程でチューブ体４内の冷媒との間で熱交換されることによって冷風となって下流側に送られる。   In the above configuration, when air is sent from the upstream side to the air passage 2a in the air conditioning case 2, the air passes through the gap between the adjacent tube bodies 4 of the evaporator 3, and the refrigerant in the tube body 4 in this passing process. As a result of heat exchange with the air, it is cooled and sent to the downstream side.

ここで、エバポレータ３の外周面と空調ケース２の内周面との間は、上記したシール構造によってシールされている。このシール構造では、エバポレータ３と空調ケース２の間にシール部材２２が密着状態で介在されるため、シール部材２２が断熱機能やシール機能や防振機能を有する。又、エバポレータ３及び空調ケース２の凹部２０及び凸部２１とシール部材２２の内周側及び外周側嵌合突起部２３，２４，２４による嵌合構造によって、位置ずれ防止機能を有する。このような各種機能を具備するシール部材２２は、エバポレータ３側と空調ケース２側に嵌合突起部２３，２４，２４をそれぞれ設けるだけの幅寸法Ｄを有すれば足りるため、シール部材２２を小型化でき、低コストにできる。   Here, the gap between the outer peripheral surface of the evaporator 3 and the inner peripheral surface of the air conditioning case 2 is sealed by the above-described seal structure. In this seal structure, since the seal member 22 is interposed between the evaporator 3 and the air conditioning case 2 in a close contact state, the seal member 22 has a heat insulation function, a seal function, and a vibration isolation function. Moreover, the fitting structure by the recessed part 20 and the convex part 21 of the evaporator 3 and the air conditioning case 2 and the inner peripheral side and outer peripheral side fitting protrusions 23, 24, and 24 of the seal member 22 has a function of preventing misalignment. The sealing member 22 having such various functions only needs to have a width dimension D sufficient to provide the fitting protrusions 23, 24, and 24 on the evaporator 3 side and the air conditioning case 2 side. The size can be reduced and the cost can be reduced.

また、エバポレータ３の外周に凹部２０を利用してシール部材２２を装着し、このシール部材２２を装着したエバポレータ３を、そのシール部材２２の弾性圧縮変形を利用して空調ケース２内に嵌合することによって配置できる。具体的には、シール部材２２の外周側嵌合突起部２４と空調ケース２側の凸部２１間を嵌合する。従って、エバポレータ３の設置作業性が良い。つまり、従来例では、空調ケース２とシール部材との間はフラットな面同士であるため、接着材、接着テープを利用して貼着する必要があり、設置作業性が悪かったが、本発明では嵌合作業によって設置できるすれば良いため設置作業性が良い。   Further, the seal member 22 is mounted on the outer periphery of the evaporator 3 using the recess 20, and the evaporator 3 mounted with the seal member 22 is fitted into the air conditioning case 2 using the elastic compression deformation of the seal member 22. It can be arranged by doing. Specifically, the outer peripheral side fitting protrusion 24 of the seal member 22 and the convex portion 21 on the air conditioning case 2 side are fitted. Therefore, the installation workability of the evaporator 3 is good. That is, in the conventional example, since the air-conditioning case 2 and the sealing member are flat surfaces, it is necessary to stick using an adhesive or an adhesive tape, and the installation workability is poor. Then, it is only necessary to be able to install by fitting work, so the installation workability is good.

この実施形態では、シール部材２２は、環状に連続した形態であるので、切れ目の箇所でのシール漏れが発生することはない。つまり、切れ目があるシール部材の場合には、その切れ目の箇所でシール漏れの恐れがあるが、この実施形態のような形態ではその恐れがない。   In this embodiment, the seal member 22 has a continuous shape in an annular shape, so that no seal leakage occurs at the break. That is, in the case of a sealing member having a cut, there is a risk of seal leakage at the cut, but there is no such fear in the form of this embodiment.

図５はシール構造の変形例の断面図である。図５において、前記実施形態のシール構造と比較するに、空調ケース２の内周面には段差部である凸部２１が一箇所にのみ突設されている。そして、シール部材２２の二箇所の外周側嵌合突起部２４，２４が凸部２１を外側から挟み込むことによって嵌合されている。他の構成は前記実施形態のものと同一であるため、図面の同一構成箇所に同一符号を付してその説明を省略する。   FIG. 5 is a cross-sectional view of a modified example of the seal structure. In FIG. 5, as compared with the seal structure of the above-described embodiment, a convex portion 21 that is a stepped portion is provided on only one location on the inner peripheral surface of the air conditioning case 2. And the two outer peripheral side fitting protrusion parts 24 and 24 of the sealing member 22 are fitted by pinching the convex part 21 from the outer side. Since other configurations are the same as those of the above-described embodiment, the same reference numerals are given to the same components in the drawings, and description thereof will be omitted.

この変形例でも前記実施形態と同様の作用・効果が得られる。   Even in this modification, the same operation and effect as in the above embodiment can be obtained.

前記実施形態では、エバポレータ３の外周面と空調ケース２の内周面との互いに対向する２面に段差部である凹部２０と凸部２１，２１をそれぞれ設けたが、３面、又は、４面に設けても良い。又、エバポレータ３の外周面に段差部としての凹部２０を設けたが、凸部を設けても良く、空調ケース２の内周面に段差部としても凹部を設けたが、凸部を設けても良い。更に、凹部と凸部の数は一箇所でも、二箇所でも、又は、それ以上であっても良いことはもちろんである。   In the above embodiment, the concave portion 20 and the convex portions 21 and 21 that are stepped portions are provided on the two surfaces of the outer peripheral surface of the evaporator 3 and the inner peripheral surface of the air conditioning case 2 that face each other. It may be provided on the surface. Moreover, although the recessed part 20 as a level | step-difference part was provided in the outer peripheral surface of the evaporator 3, you may provide a convex part and although the recessed part was provided also as a level | step-difference part in the internal peripheral surface of the air-conditioning case 2, a convex part is provided. Also good. Furthermore, the number of concave portions and convex portions may be one, two, or more.

前記実施形態では、熱交換器はエバポレータ３であるが、ヒータコアなどであっても良いことはもちろんである。   In the above embodiment, the heat exchanger is the evaporator 3, but it is needless to say that it may be a heater core or the like.
