The heat exchange core portion (4) includes outer fins (16), a refrigerant flow pipe (12), a cold storage material container (15) , a refrigerant flow pipe (12), a cold storage material container (15), and a refrigerant flow The tube (12) and the outer fins (16) are provided with at least one, in this case a plurality, of lined portions (17) in this order. Hereinafter, the refrigerant flow pipe which is sandwiched between the two cold storage material containers (15) in the line portion (17) and whose right and left side surfaces are in contact with the cold storage material containers (15) is referred to as a first refrigerant flow pipe (12A). The second refrigerant flow pipe is a refrigerant flow pipe which is sandwiched between the material container (15) and the outer fins (16) and one of the left and right surfaces is in contact with the cold storage material container (15) and the other surface is in contact with the outer fins (16). 12B). That is, one pipe set (13) is formed by the two first refrigerant flow pipes (12A) arranged in the ventilation direction between the two cool storage material containers (15) in the line portion (17), The left and right side surfaces of both the first refrigerant flow pipes (12A) of 13) are in contact with the cold storage material container (15). Between the two cold storage containers (15) and the outer fins (16) in the row portion (17), the pipe assembly (13) is formed by the two second refrigerant flow pipes (12B) aligned in the ventilation direction. One of the left and right sides of both second refrigerant flow pipes (12B) of the pipe assembly (13) is in contact with the cold storage material container (15) and the other surface is in contact with the outer fins (16).
蓄冷材容器(15)の蓄冷材封入部(21)の左右両側面、すなわち左右両側壁(22)外面に、それぞれ上下方向に一定の流路長さを有するとともに上下両端が開口し、かつ凝縮水を上方から下方に流して下端開口から排水する複数の凝縮水排水溝(23)が通風方向に間隔をおいて形成されている。各凝縮水排水溝(23)は、蓄冷材容器(15)の蓄冷材封入部(21)の左右両側壁(22)に設けられて外方に膨出した２つの排水溝用凸部(24)の間に形成されており、隣り合う２つの凝縮水排水溝(23)は、両凝縮水排水溝(23)間に位置する排水溝用凸部(24)を共有している。凝縮水排水溝(23)および排水溝用凸部(24)の少なくとも一部は、風下側に向かって上方に直線状に傾斜している。各蓄冷材容器(15)の左右両側壁(22)のすべての排水溝用凸部(24)の膨出高さは等しくなっており、すべての排水溝用凸部(24)の膨出端壁の少なくとも一部が、第１間隙(14A)を形成する左右両側の管組(13)を構成する２つの冷媒流通管(12)に接した状態でろう付されている。なお、凝縮水排水溝(23)内を微量の空気も流れる。
The left and right side surfaces of the cold storage material-sealed portion (21) of the cold storage material container (15), that is, the outer surfaces of the left and right side walls (22) each have a fixed flow path length in the vertical direction and both upper and lower ends are open and condensed A plurality of condensed water drainage grooves (23) for flowing water downward from above and draining it from the lower end opening are formed at intervals in the ventilation direction. Each of the condensed water drainage grooves (23) is provided on the left and right side walls (22) of the cool storage material-sealed portion (21) of the cool storage material container (15) and bulged outward. The two adjacent condensed water drainage grooves (23) share the convexity (24) for the drainage groove located between the two condensed water drainage grooves (23). At least a part of the condensed water drainage groove (23) and the drainage groove convex portion (24) is linearly inclined upward toward the downwind side. The bulging heights of all the drainage groove convex portions (24) on the left and right side walls (22) of the respective cold accumulating material containers (15) are equal, and the bulging ends of all the drainage groove convex portions (24) At least a part of the wall is brazed in contact with two refrigerant flow pipes (12) constituting the left and right pipe sets (13) forming the first gap (14A). A small amount of air also flows in the condensed water drainage groove (23).
