ABSTRACT:
A method of producing a lightweight and corrosion-resistant heat exchanger is disclosed. An aluminum tube with a plurality of passage bores therein is formed by extrusion. A layer of a brazing material comprising an aluminum alloy having an electrode potential value lower than that of the tube material is formed on the tube surface with the aid of a non-corrosive flux. The tube is bent into a zigzag winding form so as to have a plurality of substantially parallel runs. Corrugated fin members of aluminum or aluminum alloy are placed between respective adjacent runs of the tube. The tube and the fin members are heated together up to the melting point of the brazing material so that they are bonded together by the brazing material to form the heat exchanger.
