Abstract
A heat exchanger includes a pair of hollow headers, a plurality of tubes communicated with the headers, corrugated fins disposed between adjacent tubes and at an outside of an outermost tube and a side plate disposed at an outside of an outermost corrugated fin. The header insertion end portion of the side plate is formed into the same or approximately the same cross-sectional peripheral configuration as that of an end portion of the tube, and the side plate fitting aperture is formed into the same configuration as that of the tube fitting aperture. This becomes unnecessary to form a special fitting configuration at the end portion of the side plate, and moreover the workability for forming the side plate fitting apertures and the tube fitting apertures can be enhanced, resulting in enhanced productivity, which in turn can reduce the manufacturing cost.
