換器の寸法が増大するという不都合が生じていた。The connector in the heat exchanger is provided so that the pipe can be easily connected to the header tank. Conventionally, the pipe is projected from the header tank and is connected via the connector. In the above-mentioned conventional connector structure, since the pipe is projected and connected to the connector, there is an inconvenience that the size of the heat exchanger attached to the place where the space is limited increases.

A concave mounting surface for mounting on the outer peripheral surface of the header tank is formed, a connecting surface for connecting pipes is formed on the other surface, and a through hole forming an opening is formed on the connecting surface and the mounting surface. Further, a convex bracket is integrally formed to form a rectangular shape as a whole. And
The concave mounting surface is fixed to the outer peripheral surface of the header tank.
