Abstract: The disclosed method relates to manufacturing a heat exchanger which causes no brazing defects, and a heat exchanger manufactured by the method. The method relates to manufacturing a heat exchanger having an aluminum alloy tube defining a cooling-medium flowing passage and a copper alloy tube defining a water flowing passage, wherein a heat exchange is carried out between a cooling medium flowing through the cooling-medium flowing passage and water flowing through the water flowing passage. The aluminum alloy tube and the copper alloy tube are brazed to each other at a temperature of less than 548° C.

The heat exchanger includes an aluminum tube through which a working fluid circulates and an aluminum fin which is bonded to the tube. The fin has a region B around a grain boundary, and a region A around the region B. In the region B, 5.0×104 pieces/mm2 less of Al—Fe—Mn—Si based intermetallic compound, each of which has equivalent circle diameters of 0.1 to 2.5 μm, are present. In the region A, 5.0×104 pieces/mm2 to 1.0×107 pieces/mm2 of Al—Fe—Mn—Si based intermetallic compound, each of which has equivalent circle diameters of 0.1 to 2.5 μm, are present.
