A permanently united plate heat exchanger normally comprises a plate package (1) having two end plates (3, 4) and several heat transferring plates (5) which are arranged therebetween. The end plates (3, 4) and the heat transferring plates (5) are permanently united, for instance by brazing, to a plate package the end plates of which have altogether four openings to form inlets and outlets for two heat exchange fluids. Two or more plate packages (1, 2) may be coupled together to form a plate heat exchanger. Preferably, plate packages of this kind are produced which have different numbers of heat transferring plates (5, 8).

Plate heat exchanger for heat exchange between two pressurized fluids, comprising a first plate package (2) having two end plates (6, 7) and several thin heat transferring plates (8) arranged therebetween, each of the heat transferring plates having a heat transferring portion provided with spacing
Plate heat exchanger for heat exchange between two pressurized fluids, comprising a first plate package (2) having two end plates (6, 7) and several thin heat transferring plates (8) arranged therebetween, each of the heat transferring plates having a heat transferring portion provided with spacing means to create flow passages between adjacent plates and an edge portion extending therearound, the heat transferring plates (8) further having through ports aligned with each other to form four port channels (9-12) which extend through the plate package, two of which port channels (9, 11) communicate only with the flow passages in every second plate interspace, one on each side of the heat transferring portions of the heat transferring plates, and the other two port channels (10, 12) communicate only with the flow passages in the other plate interspaces, one on each side of said heat transferring portions, the end plates (6, 7) and the heat transferring plates (8) being permanently connected with adjacent heat transferring plates both along the edge portions of the heat transferring plates and at several places distributed across their heat transferring portions in a way such that the plate package thereby is kept together against pressures exerted by the pressurized fluids on the heat transferring plates in the plate interspaces, and at least one end plate having openings, which are arranged for through flow of said two fluids and each of which communicates with one port channel, characterized in that the plate heat exchanger comprises at least one further plate package (1) of substantially the structure defined for said first plate package (2), that the plate packages (1, 2) are arranged in a way such that two (4, 6) of their end plates with openings for the two pressurized fluids-one end plate of each plate package-are situated opposite to each other and are so sealingly connected with each other around each of their openings that each of the heat exchange fluids is allowed to flow from one plate package into the other, that the plate packages are held together by members (16), which are arranged to take up pressure forces caused during operation of the plate heat exchanger by said pressurized fluids in the port channels (9-14) of the plate packages and striving at separating the plate packages from each other, but which members are insufficient to replace said permanent connection between the plates in each plate package for holding the plates together against the action of the pressurized fluids in the plate interspaces, and that at least one (7) of the other end plates (3, 7) of the plate packages has openings for through flow of heat exchange fluid.
