Corrugated heat exchanger plates (2) of a plate heat exchanger have outer edges of a similar design. A first set of the heat exchanger plates are brazed together in their outer edges and around at least two port holes, as well as, preferably, at all of the points upon the heat exchanger plates where the corrugations bear on each other. Another set of heat exchanger plates are brazed together in their outer edges and around at least two port holes only. |
