Abstract:
PCT No. PCT/SE87/00478 Sec. 371 Date Mar. 22, 1989 Sec. 102(e) Date Mar. 22, 1989 PCT Filed Oct. 19, 1987 PCT Pub. No. WO88/03253 PCT Pub. Date May 5, 1988.In a series of heat exchange plates (5, 6), each being rectangular with ports (7, 8, 9, 10) in its corner portions, alternate plates (6) are fully sealed and coact with intermediate plates (5) to define two groups of elongated passages through which the respective heat exchanging fluids (A, B) flow. Each intermediate plate (5) is only partially sealed and defines with one of the two adjacent fully-sealed plates (6) an area communicating directly with the atmosphere, the partial sealing consisting of port sealing means (7a, 8a, 9a, 10a) interconnecting respective pairs of opposing ports to form channels through which the two fluids (A, B) flow without entering said area. The areas form paths through which any leakage of either fluid (A, B) can escape to the atmosphere, thus preventing contamination of either fluid by the other.
