Abstract (en)

[origin: WO03008891A1] A heat exchanger, comprising a pair of hollow headers (1) and (1), a large number of tubes (3) communicably connected to the headers (1) and (1), corrugated fins (4) disposed between the tubes (3) and on the outer sides of the outermost tubes (3), and side plates (5) disposed on the outer sides of the outermost corrugated fins (4), wherein the outer peripheral shape of the cross sections of the end parts of the side plates (5) is formed in the same shape or generally in the same shape as the outer peripheral shape of the end parts of the tubes (3), and side plate fitting holes (7) and the tube fitting holes (6) provided in the headers (1) are formed in the same shape or generally in the same shape, whereby any special fitting shape must not be formed at the end parts of the side plates (5), a workability for forming the side plate fitting holes (7) and the tube fitting holes (6) in the headers (1) can be increased, a productivity can be increased, and a cost can be reduced.
