PROCESS FOR PRODUCING MEMBER FOR HEAT EXCHANGER AND MEMBER FOR HEAT EXCHANGER

摘要

In supplying a flux to a member for heat exchangers which is to be brazed, a given amount of the flux is stably adhered to a brazing area without interposing any substance which becomes unnecessary for the brazing, such as a binder. In producing a member for heat exchangers, particles comprising a flux are sprayed over a surface of a base made of aluminum or an alloy thereof at a temperature lower by at least 30°C than the melting point of the flux so as to cause the particles to collide against the surface at an average speed of 100 m/sec or higher and thereby mechanically adhere the particles thereto.
