A heat exchanger for a refrigerant fluid circuit is disclosed which includes a plurality of tubes which have opposite first and second open ends. A plurality of fin units are disposed between the plurality of tubes. The first and second header pipes have at least one open end and are fixedly disposed at the first and second opposite open ends of the tubes, respectively. The open ends of the tubes are disposed in fluid communication with the interior of the header pipes, and the heat exchanger is linked in fluid communication to external elements of the circuit through the first and second header pipes. The first and second header pipes are respectively formed by bending rectangular plate members into a tubular shape, and the rectangular plate members have a plurality of slits and joint portions such that when the plate is bent into the tubular shape slots are formed for the insertion of the ends of the tubes. Extensible joints are formed by the joint portions such that when the plate member is bent into a tubular shape the joint portions will project outwardly from the circumference. The rectangular plates are made of aluminum clad plates which include aluminum and brazing materials coated on at least one surface of the aluminum cores. A heat exchanger results, thus having a high corrosion resistance and deformation resistance to high pressure fluid passing through the header pipe. Also, the heat exchanger can be manufactured inexpensively.
