Abstract
In supplying flux to a brazing heat exchanger member, a given amount of the flux is stably adhered to brazing portions without interposing any substance which becomes unnecessary for the brazing such as binder. In manufacturing a heat exchanger member, particles containing flux are injected to a surface of a substrate made of aluminum or its alloy at a temperature lower than a melting point of the flux by 30° C. or more to collide against the surface at an average speed of 100 m/sec or higher to thereby mechanically adhere the particles thereto.
