Description

本発明は自動車に搭載されて車内に空調風を供給する空調ユニットに組み込まれる蓄冷熱交換器に関する。   The present invention relates to a cold storage heat exchanger incorporated in an air conditioning unit that is installed in an automobile and supplies conditioned air into the vehicle.

車両の一時停止時にエンジンの駆動を停止するアイドリングストップ機能を搭載した車両が提案されている。このアイドリングストップ機能を搭載した車両では、アイドリングストップ時に、エンジンからの駆動により作動している冷媒圧縮用の圧縮機も停止する。冷媒圧縮機が停止すると所望の空調風を車室内に送ることができない。特許文献１には、アイドリングストップ時でも冷風を供給するために蓄冷材を予め蒸発器の近傍に設けておき、蒸発器への冷媒の供給が停止しても蓄冷材と空気との熱交換によって冷風を供給することができるようにした構造の蓄冷熱交換器が記載されている。   There has been proposed a vehicle equipped with an idling stop function for stopping driving of the engine when the vehicle is temporarily stopped. In a vehicle equipped with this idling stop function, the compressor for refrigerant compression that is operating by driving from the engine also stops when idling is stopped. When the refrigerant compressor stops, the desired conditioned air cannot be sent into the passenger compartment. In Patent Document 1, a cold storage material is provided in the vicinity of the evaporator in advance in order to supply cold air even when idling is stopped, and heat exchange between the cold storage material and air is performed even when the supply of refrigerant to the evaporator is stopped. A cold storage heat exchanger having a structure capable of supplying cold air is described.

特許文献１に記載された蓄冷熱交換器では、空気流れの後流側（下流側）に蓄冷材を内蔵した蓄冷器を配置し、通常走行による冷媒圧縮機の作動により形成された冷風で蓄冷器に蓄冷しておき、アイドリングストップ時にこの蓄冷器を通過する空気を冷却している。   In the regenerator heat exchanger described in Patent Document 1, a regenerator with a built-in regenerator material is arranged on the downstream side (downstream side) of the air flow, and the regenerator is stored with cold air formed by the operation of the refrigerant compressor by normal running. It cools in the cooler and cools the air that passes through this cooler when idling stops.

特表２００９−５２５９１１号公報Special table 2009-525911

しかしながら、特許文献１に記載された蒸発器の後流側に蓄冷器を配置した構造では、蓄冷熱交換器全体の厚みが増加してしまい、空調ユニット内でのスペースが増加するなど搭載性が悪い。また、蓄冷器を製造して組み込む分、部品点数が増加し、重量、製造コストが増加してしまう。   However, in the structure in which the regenerator is arranged on the downstream side of the evaporator described in Patent Document 1, the overall thickness of the regenerator heat exchanger is increased, and the space in the air conditioning unit is increased. bad. Moreover, since the regenerator is manufactured and incorporated, the number of parts increases, and the weight and manufacturing cost increase.

そこで、本発明は、蓄冷機能を付加しても、蓄冷熱交換器の空気流れ方向の厚みを増やすことなく空調ユニットへの搭載性を向上することができ、重量、製造コストの増加を抑制することが可能な蓄冷熱交換器の提供を目的とする。   Therefore, the present invention can improve the mountability to the air conditioning unit without increasing the thickness of the cold storage heat exchanger in the air flow direction even if the cold storage function is added, and suppress the increase in weight and manufacturing cost. The purpose is to provide a regenerative heat storage heat exchanger.

上記目的を達成するため本発明は、空気の流れ方向に対して交差する方向に沿って上下に配置され内部に冷媒が供給される一対の冷媒タンクと、一対の冷媒タンク間に空気流れ方向に対して交差する方向に複数列配置され冷媒タンクから供給された冷媒と冷媒タンク間を通過する空気との間で熱交換する冷媒チューブと、冷媒チューブに供給されて冷媒タンク間を通過する空気により冷却される蓄冷材とを備え、冷媒チューブには冷媒タンクから供給された冷媒が通過する冷媒通路が空気流れ方向に沿って所定の隙間を空けて複数箇所設けられた蓄冷熱交換器であって、冷媒通路間の隙間内に、蓄冷材が貯留される蓄冷材貯留部を設けたことを特徴としている。   In order to achieve the above object, the present invention provides a pair of refrigerant tanks that are vertically arranged along a direction intersecting with the air flow direction and in which a refrigerant is supplied to the inside, and the air flow direction between the pair of refrigerant tanks. A refrigerant tube arranged in a plurality of rows in a direction crossing each other and heat exchanged between the refrigerant supplied from the refrigerant tank and the air passing between the refrigerant tanks, and the air supplied to the refrigerant tube and passing between the refrigerant tanks A refrigerant storage heat exchanger having a refrigerant passage through which refrigerant supplied from a refrigerant tank passes and is provided at a plurality of positions with a predetermined gap along the air flow direction. In the gap between the refrigerant passages, a cool storage material storage section for storing the cool storage material is provided.

本発明によれば、冷媒チューブに設けた空気流れ方向に沿って複数箇所設けられた冷媒通路間の隙間に蓄冷材が貯留される蓄冷材貯留部を設けたことにより、別体の蓄冷器を蓄冷熱交換器の後流側に設けないので、その分、蓄冷熱交換器の空気流れ方向の厚みを増やすことなく空調ユニットへの搭載性を向上することができる。又、別体の蓄冷器を製造して組み込む必要がないので、部品点数が増加することがなく、重量、製造コストの増加を抑制することができる。   According to the present invention, a separate regenerator is provided by providing a regenerator storage part for storing a regenerator in gaps between refrigerant passages provided at a plurality of locations along the air flow direction provided in the refrigerant tube. Since it is not provided on the downstream side of the cold storage heat exchanger, the mountability to the air conditioning unit can be improved without increasing the thickness of the cold storage heat exchanger in the air flow direction. Further, since it is not necessary to manufacture and incorporate a separate regenerator, the number of parts does not increase, and an increase in weight and manufacturing cost can be suppressed.

FIG. 1 is an overall perspective view, FIG. 2 is a side view, and FIG. 3 is a sectional view taken along line MM in FIG. 4 is a perspective view of the refrigerant tube 3, and FIG. 5 is a plan view of the refrigerant tube 3.

図１及び図２に示すように、本実施形態の蓄冷熱交換器１は、一対の冷媒タンク２と、一対の冷媒タンク２の間に配置された冷媒チューブ３と、隣接する冷媒チューブ３の間に設けられたフィン４とを備えている。   As shown in FIGS. 1 and 2, the regenerative heat exchanger 1 of this embodiment includes a pair of refrigerant tanks 2, a refrigerant tube 3 disposed between the pair of refrigerant tanks 2, and an adjacent refrigerant tube 3. And fins 4 provided therebetween.

一対の冷媒タンク２は空気の流れ方向Ａに対して交差する方向に沿って上下に配置されており、内部に冷媒が供給される。   The pair of refrigerant tanks 2 are arranged up and down along a direction intersecting the air flow direction A, and the refrigerant is supplied to the inside.

冷媒チューブ３は上下一対の冷媒タンク２の間に空気流れ方向Ａに対して交差する方向（直交する方向）に複数列配列されることにより上下一対の冷媒タンク２を連結している。冷媒チューブ３の内部には冷媒タンク２から冷媒が供給され、供給された冷媒と冷媒タンク２の間を通過する空気との間で熱交換する。この冷媒チューブ３の内部には蓄冷材（図示省略）が配置される。   The refrigerant tubes 3 connect a pair of upper and lower refrigerant tanks 2 by being arranged in a plurality of rows in a direction intersecting (orthogonal to) the air flow direction A between the pair of upper and lower refrigerant tanks 2. The refrigerant is supplied from the refrigerant tank 2 into the refrigerant tube 3, and heat is exchanged between the supplied refrigerant and the air passing between the refrigerant tanks 2. A regenerator material (not shown) is disposed inside the refrigerant tube 3.

図３〜図５に示すように、冷媒チューブ３は空気の流れ方向Ａに沿って冷媒通路１１、１２が間隔を有して設けられている。それぞれの冷媒通路１１、１２は図４及び図５に示すように複数の通路部１１ａ、１２ａを横並び状に設けることにより形成されている。冷媒通路１１、１２の長さ方向の両端部は開口されることにより冷媒通路開口部１１ｂ、１２ｂとなっている。長さ方向の両端部の冷媒通路開口部１１ｂ、１２ｂが、上下一対の冷媒タンク２に差し込まれることにより冷媒タンク２からの冷媒が冷媒通路１１、１２に供給される。   As shown in FIGS. 3 to 5, the refrigerant tube 3 is provided with refrigerant passages 11 and 12 at intervals along the air flow direction A. Each refrigerant passage 11 and 12 is formed by providing a plurality of passage portions 11a and 12a side by side as shown in FIGS. Both ends of the refrigerant passages 11 and 12 in the length direction are opened to form refrigerant passage openings 11b and 12b. The refrigerant passage openings 11 b and 12 b at both ends in the length direction are inserted into the pair of upper and lower refrigerant tanks 2, whereby the refrigerant from the refrigerant tank 2 is supplied to the refrigerant passages 11 and 12.

冷媒通路１１、１２の間には蓄冷材が貯留される蓄冷材貯留部１３、１４が設けられている。蓄冷材貯留部１３、１４は横並び状に設けられることにより、冷媒通路１１、１２の間に空気の流れ方向Ａに沿って設けられている。この蓄冷材貯留部１３、１４は冷媒通路１１、１２と一体となって冷媒チューブ３に形成されている。このように蓄冷材貯留部１３、１４が冷媒通路１１、１２の間に一体に設けられることにより、別体の蓄冷器を設ける必要がなくなる。   Between the refrigerant passages 11 and 12, cold storage material storage portions 13 and 14 in which the cold storage material is stored are provided. The regenerator storage parts 13 and 14 are provided side by side, and are provided along the air flow direction A between the refrigerant passages 11 and 12. The cold storage material storage portions 13 and 14 are formed in the refrigerant tube 3 integrally with the refrigerant passages 11 and 12. Thus, since the cool storage material storage parts 13 and 14 are integrally provided between the refrigerant passages 11 and 12, it is not necessary to provide a separate cool storage unit.

図３は冷媒タンク２の内部を示し、アッパープレート１５、ミドルプレート１６及びロアプレート１７が組み付けられることにより形成されている。アッパープレート１５とミドルプレート１６の間は冷媒供給通路２０となっている。また、ミドルプレート１６とロアプレート１７との間は蓄冷材が貯留される蓄冷材タンク部１９となっている。図３に示すように、蓄冷材貯留部１３、１４の長さ方向の両端部は、開口されることにより蓄冷材貯留部開口部１３ｂ、１４ｂとなっており、この蓄冷材貯留部開口部１３ｂ、１４ｂが蓄冷材タンク部１９に差し込まれることにより蓄冷材タンク部１９内の蓄冷材が蓄冷材貯留部１３、１４に供給されて貯留される。   FIG. 3 shows the inside of the refrigerant tank 2, which is formed by assembling the upper plate 15, the middle plate 16, and the lower plate 17. A refrigerant supply passage 20 is provided between the upper plate 15 and the middle plate 16. Further, between the middle plate 16 and the lower plate 17 is a cold storage material tank portion 19 in which the cold storage material is stored. As shown in FIG. 3, both end portions in the length direction of the regenerator storage parts 13 and 14 are opened to form regenerator storage part openings 13b and 14b, and this regenerator storage part opening 13b. , 14b is inserted into the cool storage material tank unit 19 so that the cool storage material in the cool storage material tank unit 19 is supplied to the cool storage material storage units 13 and 14 and stored therein.

ここで、図３に示すように、冷媒供給通路２０は冷媒タンク２の外側に設けられ、蓄冷材タンク部１９は冷媒タンク２の内側に設けられることにより冷媒タンク２の内部が二重構造となっている。このような構造では、冷媒通路開口部１１ｂ、１２ｂが冷媒タンク２の外側に位置し、蓄冷材貯留部開口部１３ｂ、１４ｂが冷媒タンク２の内側に位置する。   Here, as shown in FIG. 3, the refrigerant supply passage 20 is provided outside the refrigerant tank 2, and the cold storage material tank portion 19 is provided inside the refrigerant tank 2, so that the inside of the refrigerant tank 2 has a double structure. It has become. In such a structure, the refrigerant passage openings 11 b and 12 b are located outside the refrigerant tank 2, and the cool storage material reservoir openings 13 b and 14 b are located inside the refrigerant tank 2.

アッパープレート１５とミドルプレート１６との間には板状の仕切り部材１８が掛け渡されており、仕切り部材１８によって冷媒供給通路２０が空気の流れ方向Ａに沿って第１冷媒供給通路２１と第２冷媒供給通路２２とに分離されている。一方の冷媒通路１１の長さ方向の両端部の冷媒通路開口部１１ｂが第１冷媒供給通路２１に差し込まれることにより第１冷媒供給通路２１と連通している。他方の冷媒通路１２の長さ方向の両端部の冷媒通路開口部１２ｂが第２冷媒供給通路２２に差し込まれることにより第２冷媒供給通路２２と連通している。これにより冷媒供給通路２０（２１、２２）内の冷媒が冷媒通路１１、１２に供給されて上下一対の冷媒タンク２の間を冷媒が移動する。   A plate-shaped partition member 18 is stretched between the upper plate 15 and the middle plate 16, and the partition member 18 causes the coolant supply passage 20 to move along the air flow direction A with the first coolant supply passage 21 and the first plate. It is separated into two refrigerant supply passages 22. The refrigerant passage openings 11 b at both ends in the length direction of one refrigerant passage 11 are connected to the first refrigerant supply passage 21 by being inserted into the first refrigerant supply passage 21. The refrigerant passage openings 12 b at both ends in the length direction of the other refrigerant passage 12 are connected to the second refrigerant supply passage 22 by being inserted into the second refrigerant supply passage 22. Thereby, the refrigerant in the refrigerant supply passage 20 (21, 22) is supplied to the refrigerant passages 11, 12, and the refrigerant moves between the pair of upper and lower refrigerant tanks 2.

図１及び図５に示すように、フィン４は連続した波形状に形成されており、隣接する冷媒チューブ３の間に設けられて隣接する冷媒チューブ３の間での伝熱を行う。これによりフィン４は空気が冷媒チューブ３の間を通過する際に空気を冷却する。   As shown in FIGS. 1 and 5, the fin 4 is formed in a continuous wave shape, and is provided between the adjacent refrigerant tubes 3 to transfer heat between the adjacent refrigerant tubes 3. Accordingly, the fin 4 cools the air when the air passes between the refrigerant tubes 3.

このような実施形態では、空気の流れ方向Ａに沿って複数配置された冷媒通路１１、１２の間に蓄冷材が貯留される蓄冷材貯留部１３、１４が設けられているため、アイドリングストップ時において、冷媒の供給が停止しても、蓄冷材貯留部１３、１４に貯留された蓄冷材によって空気を熱交換して冷風とすることができる。この蓄冷材貯留部１３、１４が冷媒通路１１、１２の間に設けられているため、別体の蓄冷器を蓄冷熱交換器１の後流側に設ける必要がなくなる。このため、蓄冷熱交換器１の空気流れ方向の厚みを増やすことなく、空調ユニットへの搭載性を向上させることができる。   In such an embodiment, since the cold storage material storage portions 13 and 14 in which the cold storage material is stored are provided between the plurality of refrigerant passages 11 and 12 arranged along the air flow direction A, when idling is stopped. However, even if supply of a refrigerant | coolant stops, air can be heat-exchanged with the cool storage material stored in the cool storage material storage parts 13 and 14, and it can be set as cold wind. Since the regenerator storage units 13 and 14 are provided between the refrigerant passages 11 and 12, it is not necessary to provide a separate regenerator on the downstream side of the regenerator heat exchanger 1. For this reason, the mounting property to an air conditioning unit can be improved, without increasing the thickness of the cool storage heat exchanger 1 in the air flow direction.

又、別体の蓄冷器を設ける必要がないため、部品点数が増加することがなく、重量の増加を抑えることができると共に製造コストを低減させることができる。   Moreover, since it is not necessary to provide a separate regenerator, the number of parts does not increase, an increase in weight can be suppressed, and the manufacturing cost can be reduced.

又、蓄冷材貯留部１３、１４が空気の流れ方向Ａに沿った冷媒通路１１、１２の間に設けられていることにより、蓄冷材貯留部１３、１４も空気の流れＡに沿って設けられており、蓄冷材貯留部１３、１４が空気の流れを遮ることがないため、蓄冷熱交換器１を通過する空気の抵抗が増加することがなく、空調風を効率的に車内に供給することができる。   Further, since the regenerator storage parts 13 and 14 are provided between the refrigerant passages 11 and 12 along the air flow direction A, the regenerator storage parts 13 and 14 are also provided along the air flow A. Since the regenerator storage parts 13 and 14 do not block the air flow, the resistance of the air passing through the regenerator heat exchanger 1 does not increase, and the conditioned air is efficiently supplied into the vehicle. Can do.

又、蓄冷材貯留部１３、１４と冷媒通路１１、１２とを冷媒チューブ３に一体に形成しているため、部品点数を削減することができ、組み立てを容易に行うことができる。   Moreover, since the cool storage material storage parts 13 and 14 and the refrigerant paths 11 and 12 are integrally formed in the refrigerant tube 3, the number of parts can be reduced and assembly can be performed easily.

又、蓄冷材貯留部１３、１４に蓄冷材を貯留しない場合には、蓄冷熱交換器１を空調ユニットの通常の蒸発器としても使用することができ、アイドリングストップ機能を有していない車両に対してもそのまま用いることができる。   Moreover, when not storing a cool storage material in the cool storage material storage parts 13 and 14, the cool storage heat exchanger 1 can be used also as a normal evaporator of an air-conditioning unit, and the vehicle which does not have an idling stop function. It can also be used as it is.

図６〜図８は本発明の別の実施形態の蓄冷熱交換器１を示す。これらの実施形態の蓄冷熱交換器１においては、冷媒チューブ３に凹部３１が形成されている。凹部３１はそれぞれの冷媒チューブ３の両方の外面に上下方向に沿って形成されている。図６〜図８に示すように、凹部３１は冷媒チューブ３の間に設けられたフィン４とは非接触となるように冷媒チューブ３に形成されている。   6-8 shows the cool storage heat exchanger 1 of another embodiment of this invention. In the cold storage heat exchanger 1 of these embodiments, a recess 31 is formed in the refrigerant tube 3. The recess 31 is formed along the vertical direction on both outer surfaces of the respective refrigerant tubes 3. As shown in FIGS. 6-8, the recessed part 31 is formed in the refrigerant | coolant tube 3 so that it may become non-contact with the fin 4 provided between the refrigerant | coolant tubes 3. As shown in FIG.

図６及び図７に示す実施形態において、凹部３１は冷媒チューブ３の蓄冷材貯留部１３、１４の間に形成されており、蓄冷材貯留部１３、１４の冷却によって冷媒チューブ３外面に発生した凝縮水を排水するように機能する。これにより排水性が向上する。   In the embodiment shown in FIGS. 6 and 7, the recess 31 is formed between the cold storage material storage portions 13 and 14 of the refrigerant tube 3, and is generated on the outer surface of the refrigerant tube 3 due to cooling of the cold storage material storage portions 13 and 14. It functions to drain condensed water. This improves drainage.

図８に示す実施形態において、凹部３１は冷媒チューブ３の蓄冷材貯留部１３、１４の間と、蓄冷材貯留部１３、１４と隣接する冷媒通路１１、１２の間に形成されている。これにより蓄冷材貯留部１３、１４の冷却によって発生した凝縮水及び冷媒通路１１、１２の冷却によって発生した凝縮水の双方を排水することができる。これにより排水性が向上する。   In the embodiment shown in FIG. 8, the recess 31 is formed between the regenerator storage parts 13 and 14 of the refrigerant tube 3 and between the refrigerant passages 11 and 12 adjacent to the regenerator storage parts 13 and 14. Thereby, both the condensed water generated by the cooling of the regenerator storage parts 13 and 14 and the condensed water generated by the cooling of the refrigerant passages 11 and 12 can be drained. This improves drainage.

なお、以上の実施形態では、蓄冷材貯留部１３、１４を２つ設けているが、その数は単数であっても良く、３以上であっても良い。   In addition, in the above embodiment, although the two cool storage material storage parts 13 and 14 are provided, the number may be single and may be three or more.
