Abstract
A plate stack includes a plurality of plates, each including corrugated portions formed on front and back surfaces thereof. First and second heat exchange flow passages are formed between plates, arranged alternately along stacking direction of the plates. Each plate has two through holes penetrating the front and back surfaces, through which the first heat exchange fluid is introduced and derived. The plate stack includes first partition weirs formed on at least one of two plate surfaces, the two plate surfaces forming a corresponding one of the first heat exchange flow passages therebetween. First partition weirs are symmetrically and obliquely arranged with respect to a center line connecting centers of two through holes as viewed from the stacking direction. A flow passage is formed along the center line on a side of at least one of the two through holes, from which first heat exchange fluid is introduced.
