ABSTRACT:
Each of heat exchanging units which constitute a heat exchanger is composed of a first plate and a second plate respectively provided with a through hole, an inlet hole and a communication hole and formed with crowns adapted to form a space through which a second fluid flows, a collar and a ring, both surfaces of which are placed in contact with inner surfaces of both first and second plates, are interposed between the first and second plates to form a space through which a first fluid flows. The collar is disposed being axially aligned with a flange portion of the through bolt extending through the heat exchanging units whereby the load resistance of the heat exchanging units can be increased. Moreover, with this arrangement, the heat exchanging units may be easily stacked.
