<p>A heat exchanger has a connector (7) for connecting a receiver tank (4) brazed to a header pipe (3) and the receiver tank (4) connected to the connector (7) by male screw parts, wherein the connector (7) is formed to have a brazing face (7a) against the header pipe (3) narrower than a mating face (7b) against the receiver tank (4). The connector (7) has a plurality of holes (73), (73) into which a plurality of male screw parts are inserted or screwed, and the holes (73), (73) are formed symmetrically or substantially symmetrically on the brazing face (7a) against the header pipe (3) with respect to a straight line connecting the center of an outflow path (71) and that of an inflow path (72) on the mating face (7b) against the receiver tank (4). And, a groove (74) which divides the brazing face (7a) is formed between the inflow path (71) and the outflow path (72) on the brazing face (7a) against the header pipe (3). <IMAGE></p> |
