Claims

[Scope of utility model registration request]

A flange provided on the periphery of the open end of the tank is fitted 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 fitted on the outside of the annular groove is attached to the outer peripheral wall. In the heat exchanger assembly structure in which the tank and the seat plate are fixed by bending the provided claw pieces toward the tank side, a groove is provided on the outer peripheral surface of the flange near the pipe installation opening of the tank, and the above-mentioned A notch is provided on the outer circumferential wall of the annular groove, or in addition thereto on the outer circumferential wall of the fixing member, to define an engagement protrusion that is pressed into the groove, and the claw portions of these outer circumferential walls near where the notch is provided are provided. An assembly structure of a heat exchanger characterized by the omission.
