Claims

[Scope of utility model registration request]

A flange provided on the periphery of the open end of the tank fits into an annular groove provided on the periphery of the seat plate, and a claw piece provided on the outer peripheral wall of the annular groove or a fixing member provided on the outer peripheral wall that fits on the outside of the annular groove. In the heat exchanger assembly structure in which the tank and the seat plate are fixed by bending the claw pieces toward the tank side, a protrusion is provided on the outer peripheral surface of the flange near the pipe installation opening of the tank, and the annular groove or in addition to the outer circumferential wall of the fixing member, an engagement hole is provided in which the protrusion engages;
A heat exchanger assembly structure characterized in that the claw portions of the outer peripheral wall near where the engagement holes are provided are omitted.
