Abstract

PURPOSE: To prevent corrosion of tubes used in a radiator or the like, by constituting the tubes from corrugated fins made of a bracing sheet consisting of a core material of an aluminum alloy containing a predetermined amount of Zn and a skin material of an Al-Si brazing material and pipes of an aluminum alloy having a higher electrode potential than said core material of the bracing sheet.
CONSTITUTION: A corrugated fin 1 is made from a bracing sheet which consists of a core material 5 of an aluminum alloy containing 0.5W5% of Zn and a skin material 6 made of Al-Si brazing material. On the other hand, a tube 2 for passing a work fluid is made of an aluminum alloy having an electrode potential higher than that of the core material 5 by 50mV. A heat exchanger is manufactured by coupling the fin 1 and tube 2 together by way of atmospheric brazing. With such an arrangement, it is enabled to exert sacrifical anode effect of the fin 1 effectively and appropriately and to keep the potential difference between the tube 2 and fin 1 at a value higher than 50mV, so that the corrosion of the tube 2 can be prevented.
