Claim:
1. A plate heat exchanger comprising a plate package comprised of a plurality of plate heat exchanger plates, the plurality of plate heat exchanger plates each comprising: ports and, between said ports, a heat transfer area partly divided by a barrier, wherein the ports comprise a first port, a second port, a third port and a fourth port, wherein the heat exchanger plate is provided with a first transition area between the first and second ports and the heat transfer area, a second transition area between the third and fourth ports and the heat transfer area, the first and second transition areas being provided with transition ports passing through the plate heat exchanger plate, wherein the first transition area is open towards the heat transfer area, and wherein the second transition area is separated from the heat transfer area by a sealing; and said plates forming interspaces between adjacent plates, wherein, in said interspaces, the heat transfer areas of the plates form heat transfer channels, the first transition areas form first transition sections and the second transition areas form second transition sections, wherein the first transition sections communicate with the second transition sections of adjacent interspaces, and wherein the ports form inlet and outlet conduits in the plate package, which inlet and outlet conduits extend through a plurality of adjacent intermediate interspaces of a plate package section of the plate package sealed off from the transition sections, and communicate with transition sections of interspaces of said plate package section arranged before and after said intermediate interspaces.
