換器。 In a heat exchanger in which a plurality of tubes are arranged in parallel between a pair of header pipes with their respective ends connected in communication with both header pipes, and corrugated fins are arranged between adjacent tubes, the header pipes are clad on the surface. The header pipe has a thickening material layer, and an inlet pipe and an outlet pipe for the heat exchange medium are communicatively connected to the header pipe by tightly fitting the enlarged pipes formed at each end to the end of the header pipe, and A heat exchanger characterized in that the fitting portions are brazed and joined by the brazing material layer.
