Claims

[Scope of utility model registration request]

A heat exchanger in which a plurality of tubes and fins are arranged alternately, both ends of each tube are connected to a pair of hollow headers, and the headers are provided with a joint for inlet of the heat exchange medium and a joint for the outlet of the same. As the header, a hollow molded pipe formed into a cylindrical shape such that both side edges are abutted is used as the header, and the inlet joint and/or outlet joint is used as the header. The fitting is provided with a fitting hole that is continuous with the internal flow path, and when the end of the hollow-formed pipe is fitted into the fitting hole, both side edges of the hollow-formed pipe are connected to each other, and the pipe and the fitting are connected to each other. A heat exchanger characterized in that: and are integrally joined.
