ABSTRACT:
A heat exchanger is described which includes a plurality of flat tubes for conducting refrigerant and a plurality of corrugated fins fixedly sandwiched between the flat tubes. The flat tubes and the corrugated fins jointly form a heat exchange region. First and second header pipes are fixedly and hermetically connected to the flat tubes and communicate with the interior of the flat tubes. The header pipes are also provided with inlet and outlet pipes for connecting the heat exchanger to other external elements of an automotive air conditioning system. The inlet and outlet pipes protrude from opposite sides of the header pipes in the direction of thickness of the heat exchanger which is perpendicular to the longitudinal axes of the flat tubes. One end of each of the inlet and outlet pipes is shaped so as to prevent interference with the ends of the flat tubes that are inserted into the interior of the header pipes.
