Abstract
A heat exchanger for use in an automobile air conditioning system including inlet and outlet union elements is disclosed. The heat exchanger comprises 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 tubes. The header pipes are also provided with inlet and outlet union elements for connecting the heat exchanger to other external elements of the air conditioning system. Each of inlet and outlet union elements includes a rectangular parallelpiped block having a cavity formed therein. Each of the blocks is generally located at a coner of the heat exchanger defined by the top and bottom ends of the header pipes and the heat exchanger region. The cavity formed in the block allows fluid communication between the hollow interior of the header pipe and the interior of a pipe member which links the heat exchanger to external elements of the air conditioning system. The hollow interior of the flat tubes which a…
