A heat exchange core portion having a container and an outer fin is provided, and in the heat exchange core portion, a pipe assembly composed of two refrigerant flow tubes arranged at intervals in the front-rear direction is spaced apart in the left-right direction. By arranging a plurality of gaps, a gap is formed between the pipe sets adjacent in the left-right direction, and the regenerator container is a part of the whole gap and the two refrigerant flow pipes of the pipe set in the gaps. The inner fin is disposed so as to be in contact with each other, and the outer fin is disposed so as to be in contact with the plurality of gaps remaining in the entire gap so as to straddle the two refrigerant flow pipes of the pipe set, and is disposed in the cold storage material container.

On the other hand, when the compressor is stopped, the cold energy stored in the regenerator material in the regenerator material container is directly transmitted to the left and right side walls of the regenerator material container, and passes through the left and right convex parts of the heat conduction member. It is transmitted to the left and right side walls. At the same time, the cold energy stored in the part of the regenerator material in the regenerator material away from the left and right side walls of the regenerator container is transmitted to the base plate of the heat conduction member, and then transmitted to the base plate in the surface direction and left It is transmitted to the convex part and the right convex part, and is transmitted to the left and right side walls of the cold storage material container through the left convex part and the right convex part. The cold heat transmitted to the left and right side walls of the cool storage material container passes through the refrigerant flow pipe and is transmitted to the air flowing through the adjacent gap.

上述した蓄冷機能付きエバポレータ(1)は、車両のエンジンを駆動源とする圧縮機、圧縮機から吐出された冷媒を冷却するコンデンサ(冷媒冷却器)、コンデンサを通過した冷媒を減圧する膨張弁(減圧器)とともに冷凍サイクルを構成し、カーエアコンとして、停車時に圧縮機の駆動源であるエンジンを一時的に停止させる車両、たとえば自動車に搭載される。 The evaporator with a cold storage function (1) described above includes a compressor that uses a vehicle engine as a drive source, a condenser that cools the refrigerant discharged from the compressor (refrigerant cooler), and an expansion valve that depressurizes the refrigerant that has passed through the condenser ( A refrigeration cycle is configured together with a decompressor, and is mounted as a car air conditioner on a vehicle, such as an automobile, that temporarily stops an engine that is a drive source of a compressor when the vehicle is stopped.
圧縮機が作動している通常の冷房時には、圧縮機で圧縮されてコンデンサおよび膨張弁を通過した低圧の気液混相の2相冷媒が、冷媒入口(7)を通って蓄冷機能付きエバポレータ(1)の前側上ヘッダ部(5)内に入り、全冷媒流通管(12)と両下ヘッダ部(9)(11)を通って後側上ヘッダ部(6)に入り、冷媒出口(8)から流出する。冷媒が冷媒流通管(12)内を流れる間に蓄冷機能付きエバポレータ(1)のアウターフィン(16)が配置されたフィン用間隙(14B)を通過する空気と熱交換をし、冷媒は気相となって流出する。すなわち、フィン用間隙(14B)を通過する空気には、フィン用間隙(14B)の左右両側に隣接する管組(13)の冷媒流通管(12)内を流れる冷媒が有する冷熱が、アウターフィン(16)を介して伝えられて当該空気が冷却され、冷却された空気が車室内の冷房に供される。 During normal cooling when the compressor is operating, the low-pressure gas-liquid mixed-phase two-phase refrigerant compressed by the compressor and passed through the condenser and the expansion valve passes through the refrigerant inlet (7) and has an evaporator (1 ) Into the front upper header portion (5), through the entire refrigerant flow pipe (12) and both lower header portions (9) and (11) into the rear upper header portion (6) and into the refrigerant outlet (8). Spill from. While the refrigerant flows through the refrigerant flow pipe (12), heat exchange is performed with air passing through the fin gap (14B) in which the outer fin (16) of the evaporator (1) with the cold storage function is disposed, and the refrigerant is in the gas phase. And leaked. That is, in the air passing through the fin gap (14B), the cold heat of the refrigerant flowing in the refrigerant flow pipe (12) of the pipe assembly (13) adjacent to the left and right sides of the fin gap (14B) The air is transmitted via (16) to cool the air, and the cooled air is used for cooling the passenger compartment.
圧縮機の作動時には、容器用間隙(14A)の左右両側の冷媒流通管(12)内を流れる冷媒の有する冷熱は、蓄冷材容器(15)の左右両側壁(15a)(15b)に設けられた排水路用凸部(22)の膨出端壁を経て当該膨出端壁を含む左右両側壁(15a)(15b)全体に伝わり、左右両側壁(15a)(15b)から蓄冷材容器(15)内の蓄冷材に伝わる。また、蓄冷材容器(15)の左右両側壁(15a)(15b)全体に伝わった冷熱は、熱伝導部材(23)の左凸部(25A)および右凸部(25B)を通って蓄冷材に伝わる。これと同時に、蓄冷材容器(15)の左右両側壁(15a)(15b)全体に伝わった冷熱は、熱伝導部材(23)の左凸部(25A)および右凸部(25B)を通ってベース板(24)に伝わり、ベース板(24)を面方向に伝わった後にベース板(24)の全体から蓄冷材における蓄冷材容器(15)の左右両側壁(15a)(15b)から離れた部分に伝わる。こうして、蓄冷材容器(15)内の蓄冷材に冷熱が蓄えられる。 During operation of the compressor, the cold heat of the refrigerant flowing in the refrigerant flow pipes (12) on the left and right sides of the container gap (14A) is provided on the left and right side walls (15a) (15b) of the cold storage container (15). It is transmitted to the entire left and right side walls (15a) and (15b) including the bulging end wall via the bulging end wall of the drainage channel convex portion (22), and from the left and right side walls (15a) and (15b) to the cold storage container ( 15) It is transmitted to the cold storage material inside. In addition, the cold transmitted to the entire left and right side walls (15a) (15b) of the cool storage material container (15) passes through the left convex portion (25A) and the right convex portion (25B) of the heat conducting member (23). It is transmitted to. At the same time, the cold transmitted to the entire left and right side walls (15a) (15b) of the cold storage material container (15) passes through the left convex part (25A) and the right convex part (25B) of the heat conducting member (23). After being transmitted to the base plate (24) and transmitted through the base plate (24) in the surface direction, the entire base plate (24) was separated from the left and right side walls (15a) (15b) of the cool storage material container (15) in the cool storage material. It is transmitted to the part. Thus, cold heat is stored in the cold storage material in the cold storage material container (15).
また、圧縮機の作動時には、蓄冷材容器(15)表面に凝縮水が発生し、当該凝縮水は凝縮水排水路(21)内に入り、表面張力により凝縮水排水路(21)の両側の排水路用凸部(22)に沿うようにして凝縮水排水路(21)内に溜まる。溜まった凝縮水が多くなると、溜まった凝縮水に作用する重力が表面張力よりも大きくなって、凝縮水排水路(21)内を流下し、下方に排水される。 In addition, when the compressor is operating, condensed water is generated on the surface of the regenerator container (15), the condensed water enters the condensed water drainage channel (21), and the surface tension causes both sides of the condensed water drainage channel (21). It accumulates in the condensed water drainage channel (21) along the drainage channel convex portion (22). When the amount of accumulated condensed water increases, the gravity acting on the accumulated condensed water becomes larger than the surface tension, and flows down in the condensed water drainage channel (21) and drains downward.
一方、圧縮機の停止時には、蓄冷材容器(15)内の蓄冷材に蓄えられた冷熱は、直接蓄冷材容器(15)の排水路用凸部(22)の膨出端壁を含む左右両側壁(15a)(15b)全体に伝わるとともに、熱伝導部材(23)の左凸部(25A)および右凸部(25B)を経て蓄冷材容器(15)の左右両側壁(15a)(15b)全体に伝わる。これと同時に、蓄冷材容器(15)内の蓄冷材における蓄冷材容器(15)の左右両側壁(15a)(15b)から離れた部分に蓄えられた冷熱は、熱伝導部材(23)のベース板(24)に伝わり、ついでベース板(24)を面方向に伝わった後に左凸部(25A)および右凸部(25B)を経て蓄冷材容器(15)の左右両側壁(15a)(15b)全体に伝わる。蓄冷材容器(15)の左右両側壁(15a)(15b)に伝わった冷熱は、冷媒流通管(12)を通過して隣のフィン用間隙(14B)に配置されているアウターフィン(16)に伝わり、アウターフィン(16)が配置されているフィン用間隙(14B)を通過する空気に伝えられる。したがって、蓄冷機能付きエバポレータ(1)を通過した風の温度が上昇したとしても、当該風は冷却されるので、冷房能力の急激な低下が防止される。 On the other hand, when the compressor is stopped, the cold energy stored in the regenerator material in the regenerator material container (15) is directly on the left and right sides including the bulging end walls of the drainage projection (22) of the regenerator material container (15). The left and right side walls (15a) (15b) of the cold storage container (15) are transmitted to the entire wall (15a) (15b) and through the left convex part (25A) and the right convex part (25B) of the heat conducting member (23). Communicate to the whole. At the same time, the cold energy stored in the part of the regenerator material in the regenerator material (15) away from the left and right side walls (15a) (15b) of the regenerator container (15) is the base of the heat conduction member (23). It is transmitted to the plate (24), and then transmitted to the base plate (24) in the surface direction, and then the left and right side walls (15a) (15b) of the cold storage container (15) through the left convex portion (25A) and the right convex portion (25B). ) Communicate throughout. The cold heat transmitted to the left and right side walls (15a) (15b) of the cold storage material container (15) passes through the refrigerant flow pipe (12) and is disposed in the adjacent fin gap (14B). To the air passing through the fin gap (14B) where the outer fin (16) is disposed. Therefore, even if the temperature of the wind that has passed through the evaporator with a cold storage function (1) rises, the wind is cooled, so that a rapid decrease in cooling capacity is prevented.
