Claims

[Scope of utility model registration request]

In a vacuum brazing method for an aluminum heat exchanger, a flat tube with a pipe connection connector at the end is bent and meandered, fins are inserted into the parallel part of the tube, and these are integrated by brazing. When vacuum brazing the connector to the end of the tube separated by the fins, a heat reflecting plate is integrally provided with the jig on the back near the joint of the connector and the tube to collect heat at the connector joint. A method for vacuum brazing an aluminum heat exchanger, characterized by vacuum brazing the aluminum heat exchanger.
