In order to achieve the above object, in the refrigerant evaporator for exchanging heat between the cooled fluid flowing outside and the refrigerant, the first evaporator (20) arranged in series with respect to the flow direction of the cooled fluid, and A heat exchange core unit including a second evaporation unit (10), and each of the first evaporation unit (20) and the second evaporation unit (10) is configured by stacking a plurality of tubes (111, 211) through which a refrigerant flows. (11, 21) and a pair of tank parts (12, 13, 22, and 2) connected to both ends of the plurality of tubes (111, 211) and collecting or distributing refrigerant flowing through the plurality of tubes (111, 211). 23), and the heat exchange core part (21) in the first evaporation part (20) is a first core part (21a) constituted by a part of the tube group among the plurality of tubes (211). And the remaining tube group The heat exchange core part (11) in the second evaporation part (10) is a first core part (11) in the flow direction of the fluid to be cooled among the plurality of tubes (111). 21a) and a third core part (11a) constituted by a tube group opposed to at least a part of the tube, and a tube group opposed to at least a part of the second core part (21b) in the flow direction of the fluid to be cooled. Among the pair of tank parts (22, 23) in the first evaporation part (20), one tank part (23) is from the first core part (21a). A first refrigerant collecting part (23a) for collecting refrigerant and a second refrigerant collecting part (23b) for collecting refrigerant from the second core part (21b) are included, and a pair of second evaporator parts (10) Of the tank parts (12, 13) The first tank part (13) distributes the refrigerant to the third core part (11a), and the second refrigerant distribution part (13b) distributes the refrigerant to the fourth core part (11b). The first evaporation section (20) and the second evaporation section (10) are configured to include a first communication section (31a) that guides the refrigerant of the first refrigerant assembly section (23a) to the second refrigerant distribution section (13b). , 32b, 33a) and the refrigerant replacement part (30) having the second communication part (31b, 32a, 33b) for guiding the refrigerant of the second refrigerant assembly part (23b) to the first refrigerant distribution part (13a). The first refrigerant distribution section (13a) is connected to the second communication section (31b, 32a, 33b), and the refrigerant from the second refrigerant assembly section (23b) is distributed to the first refrigerant distribution section (13a). The refrigerant inlet (14a) is provided to flow into the section (13a). Thus, the second refrigerant collecting portion (23b) is connected to the second communication portion (31b, 32a, 33b), and the refrigerant in the second refrigerant collecting portion (23b) is transferred to the first refrigerant distributing portion (13a). The refrigerant outlet (24b) is supplied to the first refrigerant distributor (13a), and the refrigerant outlet (24b) and the refrigerant inlet (14a) are different in number . A flow rate adjusting means (15) for adjusting the flow rate of the refrigerant flowing in the refrigerant distribution section (13a) is provided .
これによれば、第２冷媒集合部（２３ｂ）内の冷媒を第１冷媒分配部（１３ａ）へ流出させる冷媒流出口（２４ｂ）と、第２冷媒集合部（２３ｂ）からの冷媒を第１冷媒分配部（１３ａ）に流入させる冷媒流入口（１４ａ）との数が異なっているので、第２冷媒集合部（２３ｂ）から流出して第１冷媒分配部（１３ａ）に流入する冷媒流路が途中で分岐することになる。このため、当該冷媒流路を流通する冷媒の圧力損失を低減できるので、第３コア部（１１ａ）において液相冷媒が偏って分配されることを抑制することが可能となる。したがって、冷媒蒸発器における被冷却流体の冷却性能の低下を抑制することが可能となる。

According to this, the refrigerant outlet (24b) that causes the refrigerant in the second refrigerant assembly (23b) to flow out to the first refrigerant distributor (13a) and the refrigerant from the second refrigerant assembly (23b) are the first. Since the number of refrigerant inlets (14a) flowing into the refrigerant distributor (13a) is different, the refrigerant flow path flows out of the second refrigerant assembly (23b) and flows into the first refrigerant distributor ( 13a ) Will branch on the way. For this reason, since the pressure loss of the refrigerant | coolant which distribute | circulates the said refrigerant | coolant flow path can be reduced, it becomes possible to suppress that a liquid phase refrigerant is distributed unevenly in the 3rd core part (11a). Therefore, it is possible to suppress a decrease in the cooling performance of the fluid to be cooled in the refrigerant evaporator.
Further, in the first refrigerant distributor (13a), the refrigerant flowing from the refrigerant inlet (14a) diffuses when passing through the flow rate adjusting means (15), so that the refrigerant is distributed in the first refrigerant distributor (13a). Can be improved.
