ABSTRACT:
A heat exchanger includes a pair of header pipes and tubes disposed between the header pipes. Each tube is connected to the header pipes at its end portions. Each of the header pipes comprises a tubular member and a connecting plate. The tubular member defines an opening which is formed at a position in the circumferential direction of the tubular member and extends in the longitudinal direction of the tubular member. The connecting plate is installed in the defined opening of the tubular member and has a plurality of holes for inserting the end portions of the tubes therein to connect the tubes to each header pipe. The connecting plate is formed as a simple shape, and the plurality of holes are easily and precisely processed. Therefore, the tubes can be easily and efficiently connected to the header pipes and the header pipes can be inexpensively manufactured. Since a bracket for supporting the heat exchanger can be attached to a flat portion formed on the tubular member by fastening, the working efficiency can also be increased.
