　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 mounted on a vehicle 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ある。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 are vehicles equipped with an idling stop function that stops the engine drive 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 even if supply of the refrigerant to the evaporator is stopped, heat exchange between the cold storage material and air is performed. 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 traveling. It cools in the cooler and cools the air that passes through this cooler when idling stops.

Thereby, since a separate regenerator is not provided on the downstream side of the regenerator heat exchanger, it is possible to improve the mountability to the air conditioning unit without increasing the thickness of the regenerator heat exchanger in the air flow direction. it can. 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.

　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（第２の方向Ｃ）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 with an interval along the air flow direction A. As shown in FIGS. 4 and 5, each refrigerant passage 11, 12 is formed by providing a plurality of passage portions 11 a, 12 a side by side. Both ends of the refrigerant passages 11 and 12 in the length direction (second direction C) 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.

The cold storage material reservoirs 13 and 14 are provided along the air flow direction A between the refrigerant passages 11 and 12 by being provided side by side. The cold storage material reservoirs 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 paths 11 and 12, it is not necessary to provide a separate cool storage.
　図３は、冷媒タンク２の内部を示し、冷媒タンク２は、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との間は、冷媒供給通路２０となっている。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となっている。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, and the refrigerant tank 2 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. 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. By inserting the cold storage material storage part openings 13b and 14b into the cold storage material tank part 19, the cold storage material in the cold storage material tank part 19 is supplied to the cold storage material storage parts 13 and 14, and stored.
　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内部の蓄冷熱交換器１外寄りに設けられ、蓄冷材タンク部１９は冷媒タンク２内部の蓄冷熱交換器１内寄り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内部の外寄りに位置し、蓄冷材貯留部開口部１３ｂ、１４ｂが冷媒タンク２内部の内寄りに位置する。 Here, as shown in FIG. 3, the refrigerant supply passage 20 is provided outside the cold storage heat exchanger 1 inside the refrigerant tank 2, and the cold storage material tank portion 19 is inside the cold storage heat exchanger 1 inside the refrigerant tank 2. By being provided, the inside of the refrigerant tank 2 has a double structure. 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が掛け渡されている。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、冷媒通路１１が第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、冷媒通路１２が第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. The partition member 18 separates the refrigerant supply passage 20 into a first refrigerant supply passage 21 and a second refrigerant supply passage 22 along the air flow direction A. The refrigerant passage 11 communicates with the first refrigerant supply passage 21 by inserting the refrigerant passage openings 11 b at both ends in the length direction of the one refrigerant passage 11 into the first refrigerant supply passage 21. The refrigerant passage 12 communicates with the second refrigerant supply passage 22 by inserting the refrigerant passage openings 12 b at both ends in the length direction of the other refrigerant passage 12 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.

For this reason, at the time of idling stop, 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 parts 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.

For this reason, since the cool storage material storage parts 13 and 14 do not block the air flow, the resistance of the air passing through the cool storage 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。このため、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。 Further, the regenerator storage parts 13 and 14 and the refrigerant passages 11 and 12 are integrally formed in the refrigerant tube 3. For this reason, a number of parts can be reduced and an 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。 In the case where no regenerator material is stored in the regenerator storage units 13 and 14, the regenerator heat exchanger 1 can be used as a normal evaporator of an air conditioning unit, and the vehicle does not have an idling stop function. It can also be used as it is.
