<p>The invention relates to a cross-flow heat exchanger with a number of parallel plates which constitute partitions between channels for the two heat-exchange media. The plates are essentially of the same construction, and comprise a preferably rectangular surface (5) provided with slits (6) in the corner portions and with edge portions (7, 8; 13, 14) bent into L-shape, the outermost edge portion being co-planar with the surface (5). The slits (6) extend at an angle to the edge portions (7, 8; 13, 14) of the plate. Two opposite edge portions (7, 8) are bent in the same direction in relation to said surface (5), while the two remaining edges are bent in the opposite direction. By turning every second plate upside down, the plates (1-4) may be stacked in such a way that alternate channels (20, 21) are formed when the outermost edge portions (11, 12) are joined to the respective adjacent edge portions. Sealing strips (19) are inserted into the corner slits (6).</p> |
