Claims

[Scope of utility model registration request]

A core, a pair of header plates joined above and below the core, a header tank connected to the outside of these header plates, and an inner wall and a bottom wall integrally formed at both ends of the header plate. a concave groove that is defined by an outer wall and receives a peripheral edge of the header tank; and a presser pawl that protrudes from the outer wall and locks the peripheral edge of the header tank that is bent inward and received in the groove. and a side plate joined to both sides of the core and connecting the pair of header plates, the header plate having a tip extending in a direction opposite to the presser claw on an outer wall of the header plate. A holding claw is formed which is folded back through a bent portion so as to form a U-shaped groove between the side plate and the outer wall, and an insertion hole is opened in the bent portion of the holding claw, and an insertion hole is formed in the bent portion of the holding claw. An inner claw and a locking claw are formed at the end of the joint surface, the inner claw is joined to the inner surface of the inner wall of the header plate, and the tip of the locking claw is connected to the bottom surface of the bottom wall of the header plate. and extends by joining to the outer surface of the outer wall, and is joined to the U-shaped groove of the holding claw, further extends the tip to the outside of the holding claw through the insertion hole, and the tip extending to the outside is inserted into the U-shaped groove of the holding claw. 1. A heat exchanger characterized in that the header tank is bent to lock a peripheral edge of the header tank received in the groove.
