Description

上記1)〜9)の蓄冷機能付きエバポレータによれば、蓄冷材容器が、冷媒流通管に熱的に接触させられた容器本体部と、容器本体部の風上側または風下側に連なるとともに冷媒流通管よりも通風方向外側に突出するように設けられ、かつ厚み方向の寸法が容器本体部の厚み方向の寸法よりも大きくなった内容積増大部とを備えているので、特許文献１記載の蓄冷機能付きエバポレータのように、冷媒流通管および蓄冷材容器の長さを長くしたり、蓄冷材容器の厚み方向の寸法である容器高さを全体に高くしたりすることなく、蓄冷材容器に封入される蓄冷材の量を多くすることができる。したがって、蓄冷材容器の容器高さが全体に同一である特許文献１記載の蓄冷機能付きエバポレータ比べて小型軽量化を図ることができる。また、蓄冷材容器の容器高さが全体に同一である特許文献１記載の蓄冷機能付きエバポレータにおいて、容器高さを大きくする場合に比べて、蓄冷材を冷却するのに要する時間を短縮することが可能になり、冷房運転開始からのクールダウン性能の低下が抑制される。しかも、蓄冷材容器内に、容器本体部から内容積増大部に至るインナーフィンが配置されているので、内容積増大部内の蓄冷材も速やかに冷却されることになる。したがって、蓄冷材容器内の蓄冷材を効率良く冷却することができる。 According to the evaporator with a cold storage function of the above 1) to 9), the cold storage material container is connected to the container main body part that is in thermal contact with the refrigerant flow pipe, and to the windward side or leeward side of the container main body part, and the refrigerant flow provided so as to protrude in the air flow direction outward from the tube, and since the dimension in the thickness direction and an inner volume increasing portion which is larger than the dimension in the thickness direction of the container main body, the cold storage in Patent Document 1 Enclosed in the regenerator container without increasing the length of the refrigerant distribution pipe and the regenerator container or increasing the overall container height in the thickness direction of the regenerator container as in the case of an evaporator with a function The amount of regenerator material to be produced can be increased. Therefore, compared with the evaporator with a cool storage function of patent document 1 whose container height of the cool storage material container is the same as the whole, size reduction and weight reduction can be achieved. Moreover, in the evaporator with a cool storage function described in Patent Document 1 in which the container height of the cool storage material container is the same as a whole, the time required for cooling the cool storage material is shortened as compared with the case where the container height is increased. This makes it possible to suppress a decrease in cool-down performance from the start of cooling operation. And since the inner fin from the container main-body part to an internal volume increase part is arrange | positioned in the cool storage material container, the cool storage material in an internal volume increase part will also be cooled rapidly. Therefore, the cool storage material in the cool storage material container can be efficiently cooled.

蓄冷材容器(15)内には、容器本体部(21)の後側縁部から内容積増大部(22)の前端部に至るアルミニウム製インナーフィン(23)が、上下方向のほぼ全体にわたって配置されている。インナーフィン(23)は、前後方向にのびる波頂部(23a)、前後方向にのびる波底部(23b)、および波頂部(23a)と波底部(23b)とを連結する連結部(23c)よりなるコルゲート状である（図６参照）。インナーフィン(23)のフィン高さは全体に等しく、蓄冷材容器(15)の容器本体部(21)および内容積増大部(22)の左側壁内面と、容器本体部(21)の右側壁内面とにろう付されている。 Inside the cool storage material container (15), aluminum inner fins (23) extending from the rear edge of the container body (21) to the front end of the internal volume increasing part (22) are arranged over substantially the entire vertical direction. Has been. The inner fin (23) includes a wave crest portion (23a) extending in the front-rear direction, a wave bottom portion (23b) extending in the front-rear direction, and a connecting portion (23c) connecting the wave crest portion (23a) and the wave bottom portion (23b). Corrugated shape (see FIG. 6) . The fin height of the inner fin (23) is the same as the whole, the inner surface of the left side wall of the container body (21) and the inner volume increasing part (22) of the cold storage material container (15), and the right side wall of the container body (21) It is brazed to the inner surface.
