摘要： A heat exchanger, such as a condenser, for use in a automobile air conditioning system includes a plurality of flat tubes for conducting the refrigerant and a plurality of corrugated outer fins fixedly sandwiched between the flat tubes. First and second header pipes are fixedly and hermetically connected to the flat tubes and, thereby, communicate with the interior of the tubes. A plurality of diagonally arranged projected stripes are formed on inner surfaces of the flat tubes. First portions of the projected stripes project from a lower inner surface of the flat tubes, and second portions of the projected stripes project from an upper inner surface of the flat tubes. The first and second portions of the projected stripes are in contact with one another at the points of intersection therebetween. Thereby, refrigerant flows through the flat tubes in a turbulent flow condition, so that the heat exchanging performance of the condenser increases while maintaining the internal pressure resistance strength of the tubes.

摘要： A method of making a heat exchanger including header pipes, flat tubes extending between the header pipes and fin units extending between the flat tubes. The header pipes include a plurality of holes on one side thereof for accepting the flat tubes. On the opposite side of the header pipes is at least one slit in which a partition plate is inserted. During the formation of the header pipe, a pair of projections are formed on the ends of the slit. After the partition plate is inserted into the header pipe, the projections are bent until they engage the partition plate thereby fixedly securing the partition plate within the header pipe.
