ABSTRACT:
A heat-exchanger element of the type consisting of two sandwiched metal sheets, deformed so as to define between themselves a flow channel, has a number of apertures in the portion of the element not deformed. The one heat-exchanging fluid passes through the channel and the other through the apertures, generally in a direction perpendicular to the sandwich interface. In a preferred embodiment the apertures are formed by a punching operation in the way that tongue-like flaps are formed which affect the direction of flow, create turbulence and may serve as means spacing or supporting adjacent elements.
