A plate heat exchanger includes a number of heat transfer plates (1), which are provided adjacent to each other in such a way that they form a plate package (2) with two channels. The channels extend in heat transferring contact to each other and are arranged to convey a respective medium through the plate package. The plate package (2) includes at least two separate sections (3, 4, 5) for at least a first of said channels. Each of the sections includes a number of said plates (1), wherein this number is different for at least two of said sections. The plate heat exchanger includes also control members (24), which permit guiding of the medium in at least the first channel in such a way that it flows through either one or several arbitrary sections of said sections (3, 4, 5). |
