Claims

[Claims for Utility Model Registration] (1) A pair of metal plates 1 and 2 formed into a substantially oval shape as a whole and whose peripheral edges are liquid-tightly brazed to each other to form a monadic shape, and at least one of said plates. In an element of a drawn cup type heat exchanger, the element has heat exchange medium circulation holes 3 and 4 opened at both ends in the longitudinal direction of the element.
A large number of waveforms 7, 8 whose ridge lines intersect with each other and are inclined with respect to the center line 1 parallel to the longitudinal direction are formed on the opposing planes 5, 6 of both the metal plates 1, 2, A metal inner fin 9 is formed with parallel ridge lines in the longitudinal direction and bent into a large number of corrugations, and the corrugations contact the corrugations 7 and 8 of the metal plates 1 and 2 at the intersections of the respective ridge lines. An element of a drawn cup type heat exchanger characterized in that the element is interposed between both metal plates 1 and 2 so that the intersection points are brazed. (2) The element of the drawn cup type heat exchanger according to claim 1, wherein a space is formed between both edges of the inner fin 9 and the inner peripheral surfaces of the metal plates 1 and 2.
