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/m 2 ; 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.

摘要： A flat tube 1 comprises a pair of upper and lower walls 2, 3 opposed to each other, two side walls 4, 5 interconnecting the upper and lower walls 2, 3 at left and right opposite side edges thereof, and a covering wall 6 provided over the outer surface of the left side wall 4 and brazed to the left side wall 4. The left side wall 4 is made from a side wall forming portion 9 projecting downward from the upper wall 2 integrally therewith and a side wall forming portion 11 projecting upward from the lower wall 3 integrally therewith by brazing these portions 9, 11 as butted against each other. The covering wall 6 is made by folding a covering wall forming portion 12 formed by extending one side edge of the upper wall 2. The left side wall 4 comprising the wall forming portion 9 of the upper wall 2 and the wall forming portion 11 of the lower wall 3 can be protected.

摘要： A flat tube making platelike body 15 is in the form of a single metal plate in its entirety and comprises two flat wall forming portions 17, 18 having the same width, a connecting portion 16 for interconnecting these portions 17, 18, side wall forming portions 9, 10 projecting from the respective flat wall forming portions 17, 18 and each formed integrally with one side edge of the flat wall forming portion opposite to the connecting portion 16, and first and second reinforcing wall forming portions 11, 12 integrally formed on each of the flat wall forming portions 9, 10. The first reinforcing wall forming portions 11 are butted against the respective second reinforcing wall forming portions 12 in pairs when the metal plate is folded into a hairpin form at the connecting portion 16. The first reinforcing wall forming portions 11 are given a smaller thickness than the second reinforcing wall forming portions 12 on the other flat wall forming portion 18 butted against the respective portions 11. The platelike body 15 gives an enhanced brazing joint strength to the reinforcing wall forming portions in fabricating a flat tube, and improved pressure resistance to the flat tube to be fabricated.
