摘要： A method for surface treating a heat exchanger, a hydrophilizing treatment agent used in this method, and an aluminum heat exchanger obtained from this method are provided that excel in the initial adherence, hydrophilicity, and odor suppressibility, and can maintain these abilities for an extended time, while having little burden on the environment and the human body. The method for surface treating an aluminum heat exchanger that is brazed includes (1) a pickling treatment step; (2) a chemical conversion treatment step; and (3) a hydrophilization treatment step, in which the acidic cleaning agent contains nitric acid and sulfuric acid and contains ferric salt in a predetermined amount, the hydrophilizing treatment agent contains silica grains coated with a vinyl alcohol polymer and a polyallylamine resin.

摘要： A method for surface treating a heat exchanger and an aluminum heat exchanger obtained from this method are provided that can effectively suppress the foul odor characteristic to flux that emanates following degradation of a hydrophilic coating film and a chemical conversion coating film in a non-corrosive flux brazed heat exchanger on which flux easily remains. The method for surface treating a non-corrosive flux brazed heat exchanger made of an aluminum material conducts a pickling treatment step, a chemical conversion treatment step, and a deodorizing treatment step on the heat exchanger, in which the acidic cleaning agent contains nitric acid and sulfuric acid as well as a predetermined amount of ferric salt, and the surface treatment agent contains silica grains coated by a vinyl alcohol polymer and polyallylamine resin such that the total content of the silica grains and the vinyl alcohol polymer is a predetermined amount.

摘要： A method for manufacturing an aluminum heat exchanger includes the steps of: obtaining a heat exchanger tube 2 by forming a Zn thermally sprayed layer on a surface of an aluminum flat tube core so as to adjust Zn adhesion amount to 1 to 10 g/m2; obtaining a heat exchanger core by alternatively arranging the heat exchanger tube 2 and an aluminum fin 3 and brazing the heat exchanger tube and the fin with end portions of the heat exchanger tube connected to aluminum headers in fluid communication; and forming a chemical conversion treatment coat (corrosion resistance coat) on a surface of the heat exchanger core by subjecting the surface of the heat exchanger core to chemical conversion treatment using at least one chemical conversion treatment agent selected from the group consisting of phosphoric acid chromate, chromic acid chromate, phosphoric acid zirconium series, phosphoric acid titanium series, fluoridation zirconium series, and fluoridation titanium series. The obtained heat exchanger has a long last good corrosion resistance and can prevent occurrence of fin detachment and pit corrosion.
