Claims

[Claims for Utility Model Registration] 1 A molded plate having deep recesses at both ends and a shallow recess between them is joined to form a tank at both ends and a plurality of heat exchange elements alternating with fins to constitute a refrigerant passage connecting them. In an evaporator formed by stacking stages, five partition plates are installed in the heat exchange element closest to the outlet side so as to be sandwiched between two molded plates that constitute the heat exchange element.
In addition to forming a one-section oil return passage, a large hole is bored in the upper tank in the partition plate, and an oil return hole is bored in the lower end of the lower tank. An evaporator characterized by: 2. The evaporator according to claim 1, wherein the tanks on the lower side communicate with each other through small oil drain holes formed in the recesses of the molded plates constituting the tanks.゛
