ABSTRACT:
A heat exchanger, such as a condenser, for use in an automobile air conditioning system comprises 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. Each of the flat tubes includes a flat tube member and a corrugated inner fin. The corrugated inner fin includes a plurality of ridges which extend along the width of the flat tube member. The adjacent ridges are fixedly connected to upper and lower inner surfaces of the flat tube member so as to define a plurality of lateral hollow regions in an interior hollow portion of the flat tube member. A plurality of openings are formed in each of surfaces of the corrugated inner fin defined between the adjacent ridges so as to laterally disperse the flow of the refrigerant when the refrigerant flows through the interior hollow space of the flat tube. As a result, the heat exchange efficiency of the condenser is sufficiently improved while preventing expansion of the flat tube members.
