1. A plate heat exchanger comprising a plurality of generally rectangular plates arranged adjacent to each other and provided with turbulence-generating corrugations, said plates enclosing sealed heat exchanging passages for receiving two heat exchanging media flowing therethrough in mutually inclined main flow directions, the heat exchanger being characterized in that said corrugations extend in such directions that they form on an average a wider angle with the main flow direction of one of said media than with that of the other medium, whereby the passages for the two media provide different respective flow resistances.
