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.

The laminating body 20 has plural flow path plates 21 formed in a plate shape in which plural grooves 23 parallel to each other are concavely arranged on a flat joining face 22. Each groove 23 is set to a parallel flow path 50 parallel to a front face side by laminating each flow path plate 21 by each joining face 22. A portion other than each groove 23 of each joining face 22 forms a heat transfer path 70a to each parallel flow path 50 of a laminating direction. A flow-in path 30a and a flow-out path 40a are formed in the first and second side plates 30, 40. The flow-in path 30a and the flow-out path 40a are joined to side faces 26a, 26b of the laminating body 20, and are communicated with each parallel flow path 50. The flow-in path 30a flows a cooling medium into each parallel flow path 50. The flow-out path 40a flows the cooling medium out of each parallel flow path 50. A refrigerant flow path is constructed by the flow-in path 30a, each parallel flow path 50 and the flow-out path 40a.
