制冷剂蒸发器
摘要：
在被冷却流体与制冷剂之间进行热交换的制冷剂蒸发器(1)具备：第一热交换部(12)，制冷剂在该第一热交换部的内部流动，该第一热交换部在被冷却流体与制冷剂之间进行热交换；第二热交换部(22)，该第二热交换部与第一热交换部相对地配置，并且制冷剂在该第二热交换部的内部流动，该第二热交换部在被冷却流体与制冷剂之间进行热交换；第一箱(13)，该第一箱配置于第一热交换部的下方，将所述制冷剂向第一热交换部分配；第二箱(23)，该第二箱配置于第二热交换部的下方，收集在第二热交换部流动的制冷剂；以及第三箱(30)，该第三箱通过钎焊接合于第一箱及第二箱，将收集于第二箱的制冷剂向第一箱引导。在第一箱及第三箱的接合部(133、304)的一方形成有突出部(310～312)。在第一箱及第三箱的接合部的另一方形成有突出部插入的插入部(134～136)。
摘要（英）：

A refrigerant evaporator (1) that exchanges heat between a fluid to be cooled and a refrigerant and comprises: a first heat exchange unit (12) having the refrigerant flowing therethrough and exchanging heat between the fluid to be cooled and the refrigerant; a second heat exchange unit (22) arranged facing the first heat exchange unit, having the refrigerant flowing therethrough, and exchanging heat between the fluid to be cooled and the refrigerant; a first tank (13) arranged below the first heat exchange unit and distributing the refrigerant to the first heat exchange unit; a second tank (23) arranged below the second heat exchange unit and collecting refrigerant that has flowed through the second heat exchange unit; and a third tank (30) soldered to the first tank and the second tank and guiding the refrigerant collected in the second tank to the first tank. One of the joining sections (133, 304) between the first tank and the third tank has protruding sections (310-312) formed thereupon. The other of the joining sections between the first tank and the third tank has insertion sections (134-136) formed therein, into which the protruding sections are inserted.
