A heat exchanger for essentially counterflow heat exchange between two air flows comprises inside a housing (9) essentially parallel partitions (3) of in the air flow direction extended and stretched each with a substantial tension force (P) membranes (3', 3'') of high tensile strength, that pairwise (3', 3'') essentially gas tight enclose first channels (4) for a warmed, first air flow (1). In alternating second channels (5), surrounding said first channels (4), is propelled a second, cooled air flow (2). The membranes (3', 3'') are formed into deflated segments (31) by supporting strips (8) inside said first channels (4), by local static pressure differences ( DELTA p) between said air flows (1, 2) and by said tension force (P). |
