HEAT EXCHANGE ELEMENT

WIPO Patent Application WO/2010/125643

A1

A heat exchange element (101) has a first flow path and second flow paths perpendicular to the first flow path.  The first flow path is an undulating flow path (31) having a rectangular cross-section and formed by overlaying, with a predetermined gap in between, a first undulating plate material (11) and a second undulating plate material (12) on each other and closing opposite sides of the flow path for a fluid by gap retaining members (14).  The first undulating plate material (11) has an undulating shape undulating in the direction of the overlaying and lies in the direction of flow of the fluid, and the second undulating plate material (12) has substantially the same undulating shape as the first undulating plate material (11).  The second flow paths are straight flow paths (32) having a substantially triangular cross-section and formed by overlaying in a close contact manner a flat plate material (13) on the undulating shape of either the first undulating plate material (11) or the second undulating plate material (12) such that the straight flow paths (32) extend between both the plate materials.
