A heat exchanger having a flat tube with a plurality of fluid passageways therein, header pipes connected to opposite ends of the flat tube and inlet and outlet tubes connected to the header pipes, respectively. The inlet and outlet tubes are inserted and fitted into the corresponding ones of the header pipes and formed with axial slits in the inserted end portions. The opposite ends of the flat tube extend into header pipes through axial slits in the outer surfaces thereof and are fitted into the axial slits of the inlet and outlet tubes inserted therein. Thus, the inlet tube and the outlet tube are reliably maintained in their desired orientation. The header pipes are made of aluminum brazing sheet and, therefore, are brazed to the aluminum flat tube and the inlet and outlet aluminum tubes. |
