Claims

[Scope of utility model registration request]

An upper tank and/or a lower tank each having a water tube insertion hole and a fitting claw protruding around the insertion hole are formed by integral molding of synthetic resin, and the water tube is inserted into the insertion hole into the fitting claw. A guide notch is provided to guide the water tube, and a projecting edge is formed on the outer periphery of the water tube, and an O-ring is placed adjacent to the projecting edge.The end of the water tube is inserted into the insertion hole, and the O-ring and A heat exchanger characterized in that a projecting edge is interposed between the wall surface of the upper tank and/or the lower tank and the fitting claw.
