ABSTRACT A heat exchanger is disclosed which has a rectangular exchanger pack which consists of a plurality of individual, mutually spaced, foil- type plates which have triangular cut-outs at their corners. The plates are connected with one another in pairs in sealed manner by marginal strips extending between the cut-outs on two opposite plate margins, for the for- mation of alternately crossing throughflow passages between the plates. A frame housing surrounds the exchanger pack and consists of two covers adjacent the outer plates of the exchanger pack and four struts connecting the covers at their corners. The marginal strips to be connected rest flatly one upon the other and are mechanically connected with one another by folding over at least once. Each strut of the frame housing has a triangular recess at a corner adjacent a corner of the exchanger pack, into which recess the pack corner with its cut-outs extends. The depth of the recess is greater than the depth of the cut-outs and the recess is filled with a sealing filling of a moulding resin to beyond the cut-outs.
