ABSTRACT:
A heat exchanger includes a pair of substantially parallel header pipes and a plurality of substantially parallel tubes disposed between the pair of header pipes. Each tube defines a pair of end portions which are connected to the pair of header pipes. A plurality of rows of fins are provided along sides of the tubes. A pair of reinforcement members are provided along sides of each of the top and bottom rows of fins. Each of the pair of header pipes has a plurality of holes for inserting the end portions of the tubes to connect the tubes to each pipe of the pair of header pipes. At least one slit is formed on the end portions of each header pipe. The end portions of the reinforcement members extend through the slits to close the open ends of the header pipes. In one embodiment, each of the end portions of the reinforcement members extend through each header pipe through a pair of opposed slits and is bent to fix itself to the header pipe. The number of heat exchanger parts is thus reduced and the manufacture thereof is simplified.
