Abstract (en)
A heat exchanger (1) includes a header (2, 3) and a plurality of heat exchange tubes (4), the header (2, 3) is formed from a header member A (10) and a header member B (11) formed dividedly from each other and connected to each other, the header member A (10) being formed as a comb-like shape with slits (12) each corresponding to a tube insertion hole and the header member B (11) being abutted to the header member A (10) to complete the whole shape of the header (2, 3), a flange (17) is formed on an end portion of each heat exchange tube (4), and each heat exchange tube (4) is connected to at least the header member A (10) at a condition where the flange (17) extends on both side portions of each slit (12) and the flange (17) is hung from the header member A (10). Assembling can be facilitated, and desirable brazing becomes possible without severe management of dimensions of parts.
