ABSTRACT:
A method for manufacturing a novel heat exchanging vehicle comprising the steps of forming an inorganic surface layer over a cold rolled, aluminum or aluminum alloy sheet; treating the inorganic surface layer with a phosphoric compound solution; annealing the sheet; and forming the sheet into a predetermined shape. The resulting heat exchanging vehicle such as a fin has a good wettability and a high corrosion resistance to white rust based on the uniformity of the said surface layer.
