A heat exchanger which includes a pair of substantially parallel header pipes. A plurality of substantially parallel tubes are disposed between the pair of header pipes. Each tube defines a pair of end portions which are connected to the pair of header pipes. Each of the pair of header pipes comprises a rectangular member which has a longitudinal opening formed along one side of the rectangular member. A connecting plate is installed in the opening. The connecting plate has a plurality of holes for receiving the end portions of the tubes therein to connect the tubes to each of the pair of header pipes. According to the above structure, a heat exchanger can be easily manufactured and inexpensively produced by reducing the cost for manufacturing the header pipes. The construction of the present heat exchanger reduces the occurrence of defects in the connection of tubes.
