<p>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 (Δp) between said air flows (1, 2) and by said tension force (P).</p> |
