Abstract: Heat exchangers in general, but mere specifically cupper, Cu, brazed plate type heat exchangers formed of a plural of surface structured stacked plates brazed together by copper, show severe problems with corrosion in some regions of the world. The present invention relate to forming a protection of the plates in order to reduce the observed corrosion problems.

Abstract: The present invention relate to a plate heat exchanger including a stack of patterned heat transfer plates connected to each other by brazing or welding, were patterns of the connected neighbouring heat transfer plates forms respectively a first flow path and second flow path on the opposing sides of a heat transfer plate, said heat transfer plates comprising aligned first pair of port holes forming respectively first inlet and first outlet for a first fluid to be distributed to said first flow path, where a first end plate is connected to the stack first side outermost heat transfer plate with first opening aligned to the first inlet, and a second end plate is connected to the stack second side outermost heat transfer plate with a blank section aligned with the first inlet, where the second side outermost heat transfer plate is formed with a contacting projection connected and brazed or welded the inner surface of the second end plate.
