Abstract
A crosscurrent heat exchanger body made up of a stack of joined, parallel flow web plates (1), and a hollow chamber (5) for flow across them between each two successive web plates, with the cover layers (2,2') of successive web plates being sloped toward one another at their ends over the hollow chamber (5) enclosed between them, and being joined tightly to one another over the entire width, is disclosed.
Claims5
A crosscurrent heat exchanger body, which comprises:
- a stack of joined plastic flow web plates (1), consisting of two planar, parallel cover plates (2) and parallel webs (3) joined integrally to said cover plates, which enclose parallel hollow flow chambers (4), with a number of web plates being arranged in a stack so that their hollow chambers can carry flow in parallel, and so that a hollow cross-flow chamber (5) is located between each of two such web plates in succession in the stack, wherein the cover layers (2, 2') of each two web plates that are adjacent to a cross-flow hollow chamber (5) are sloped toward one another at their ends across the hollow chamber (5) between them, and are joined to one another over the entire width, and wherein said hollow cross-flow chambers (5) contain spacers (6) of the thickness of the hollow chambers, said spacers (6) containing hollow cross-flow chambers (7).
