Abstract
A stacking-type, multi-flow, heat exchanger includes a plurality of heat transfer tubes and fins stacked alternately, a tank formed at an end of the heat transfer tubes, and an end plate provided at an end of the tank. The heat exchanger has a projecting portion provided to a surface of an outermost tube plate, a raised portion with an opening formed through the projecting portion, and an engaging portion and a closing portion provided integrally to the end plate for engaging the raised portion and for closing an opening of the raised portion. A positional shift of the end plate at the time of temporary assembling may be prevented, and the brazing properties and the pressure resistance of the tank end portion may be increased.
