<p>A heat exchanger comprising a rectangular exchanger pack which consists of a plurality of individual, mutually spaced, foil-type plates which have triangular corner notches and are connected with one another in sealed manner on marginal strips which extend between the corner notches in pairs on two opposite plate margins for the formation of alternately crossing flow-through passages between the plates, and comprising a frame housing surrounding the exchanger pack comprising two covers disposed adjacent the outer plates of the exchanger pack and four struts connecting the covers at their corners. The marginal strips to be connected of each two adjacent plates of the exchanger pack rest flatly upon each other and are mechanically connected with each other by folding over at least once. The struts of the frame housing define a triangular recess on their side facing the edge of the exchanger pack. The pack edges with the corner notches project into these recesses. The recesses on the struts are filled out with a sealing filling made of a moulding resin to beyond the corner notches.</p> |
