摘要： A heat exchanger of an aluminum alloy assembled by a brazing method in which a radiator (10) and an oil cooler (11) are put together. A refrigerant tank (13) which covers and tightly encloses the oil cooler is made of an aluminum alloy, the solder for a brazing sheet used for the oil cooler and soldered to the inside of the tank is an aluminum alloy containing more than 7.0 wt.% and not more than 12.0 wt.% of Si, more than 0.05 wt.% and not more than 0.5 wt.% of Fe, more than 0.4 wt.% and not more than 8.0 wt.% of Cu and more than 0.5 wt.% and not more than 10.0 wt.% of Zn, the balance of aluminum and inevitable impurities. Thus, a heat exchanger of an aluminum alloy in which the refrigerant tank is united with the radiator and oil cooler in one body by soldering using the brazing material. This heat exchanger of an aluminum alloy uses a tank of an aluminum material instead of a resin tank, and it is recycled easily. The heat exchanger has a high corrosion resistance and can be fabricated without a tank caulking step.
