Abstract
Two identically folded strips enclose an intermediate space accessible at e edges of the strip, and the fold cavities opening to the outside of the strip structure are closed off at the strip edges and covered by outside cover plates over their central portions, so that one medium may be caused to flow through each of the sets of outside fold cavities and a third medium through the intermediate space. The third medium flows countercurrent to the direction of flow of the other two. Modules of four such matrices utilize inlet and outlet ducts so that the two or four matrices in a compact modular structure can be structurally repeated in accordance with the number of modules desired in the particular application. The inlet and outlet ducts have tapering flow cross-sections.
