Claims

[Scope of utility model registration request]

A heat exchanger in which the main body of the tank and the conduit pipes provided on the outer wall of the tank are molded separately, and then the conduit pipes are fitted into the connection holes formed in the joint wall of the main body of the tank to integrally connect the two. In this resin tank, when the water conduit pipe is inserted into the coupling hole of the main body of the tank, a plurality of retaining claws are formed on the outer circumferential surface of the inner end thereof, and a plurality of retaining claws are formed on the inner circumferential surface of the coupling hole along the hole direction. When the flange formed at the rear of the pawl that is inserted and engaged with each pawl guide groove comes into contact with the joint surface of the main body of the tank and is rotated in one direction, the pawl will gradually increase in groove width in the direction of rotation. The arcuate connecting groove at the inner end of the coupling hole is gradually compressed in the thickness direction and height direction, and the valley diameter is reduced. It is designed to be fitted in a state in which the compression in the horizontal direction is released, and in this state, the connecting portion of the water conduit and the coupling hole is provided with a packing that is pressed by the flange formed on the water conduit. A resin tank for a heat exchanger characterized by being equipped with a material.
