A heat exchange element of a plate type heat exchanger consists of a plurality of heat transmission plates having an equivalent shape. Each heat transmission plate is formed with flanged through-holes and openings so that each flanged through-hole and each opening are alternately located and separate from each other by a predetermined peripheral distance along a circle of the heat transmission plate. The heat transmission plates are disposed one upon another and sealingly secured to each other in such a manner that one of adjacent heat transmission plates is shifted the predetermined peripheral distance along the circle relative to the other heat transmission plate, thereby enabling to produce the heat exchanger heat exchange element by using only the heat transmission plates of the equivalent shape.

Heat exchanger

A plate type heat exchanger consists of a plurality of heat transmission plates which are piled up and secured to each other. Side wall members are interposed between the adjacent heat transmission plates, so that multiple stages of spaces are formed in the heat exchanger. Additionally, separator wall members are interposed between the adjacent heat transmission plates in such a manner that two fluid paths are defined in alternate stages of the spaces. The side wall members and the separator members are formed of rod material, thereby rendering the heat exchanger light in weight while lowering the production cost of the heat exchanger.
