Brazing of Aluminum Bimetallic Sheets in the Design of Heat Exchangers

Abstract:

Present heat exchangers should ensure very good heat transfer while having as small size, high durability and the optimum performance at low prices. Thus to achieve these goals is used as base material, aluminum in various forms, of which can be made the heat exchangers energetic efficient. Realization of aluminum heat exchangers can be properly with present requirements using the brazing joint elements. Brazing achieved joining with temperature for two base materials using a filler metal with a melting point above 450°C. A properly brazed joint is performed with a metallurgical connection between two or more metals, which is generally as strong as or stronger than the base metal used.
