Abstract

PURPOSE:To form a corrosion resistant heat transfer surface for a heat exchanger made of Al applicable to both of an evaporation heating surface and a condensation heating surface by forming an oxide film on an Al material by anodic oxidation or other method and subjecting it to a chemical treatment with an acid-base treating soln. CONSTITUTION:An oxide film is formed on the surface of an Al material by anodic oxidation or a chemical treatment with a treating soln. other than an acidic treating soln. The film is then subjected to a chemical treatment such as a chromate film forming treatment with a treating soln. contg. chromic acid, chromate, dichromate or other acid. By this chemical treatment a heating surface with superior corrosion resistance is formed in a state keeping a favorable wetting property. By applying this method to a heat exchanger, especially to the outside of the evaporator, the wetting property is improved, and water droplets between fins can be removed smoothly.
