In a heat exchanger comprising a plurality of plates (20) stacked to define between them passages (21-27) for two mutually heat exchanging fluids (A,B), and wherein at least one of the passages (e.g. an end passage 21 or 27 of the plate pack) is bounded on one side only thereof by a plate serving to exchange heat with fluid in an adjacent passage, the said one passage (or passages) is arranged to have a higher fluid flow resistance than the other passages in the plate pack conveying the same fluid as said one passage (or passages). Such higher flow resistance may be effected by providing in the walls of said one passage (or passages) a corrugation arrangement which has a higher fluid flow resistance than a corrugation arrangement provided in the walls of said other passages (e.g. Figures 4 and 5). <IMAGE> |
