Abstract:
1. A plate heat exchanger comprising a plate package having a plurality of heat exchanger plates, which are stacked onto each other and arranged in such a way that they in the plate package form first plate interspaces for a first medium and second plate interspaces for a second medium, a casing, which encloses the plate package and which comprises a circular cylindrical outer envelope and two end plate members, the outer envelope defining a center axis which extends through the two end plate members, a first inlet and a first outlet, which are adapted to convey the first medium into and out from the plate heat exchanger and extend through a respective one of the two end plate members, and a second inlet and a second outlet, which are adapted to convey the second medium into and out from the plate heat exchanger, each of the heat exchanger plates comprising an opening which forms a space in the plate package, wherein the space communicates with the first inlet and the first outlet, and the plate heat exchanger comprises, for each of the first plate interspaces, an inlet opening for the first medium from the space into the first plate interspace and an outlet opening for the first medium from the first plate interspace to the space, wherein the plate heat exchanger comprises a separation device disposed in the space and arranged to divide the space into a first part space and a second part space, which part spaces extend through the opening of all heat exchanger plates, and wherein the first part space forms a first inlet chamber, which extends through the opening of two or more heat exchanger plates and permits communication between the first inlet and the inlet openings, and the second part space forms a first outlet chamber, which extends through the opening of two or more heat exchanger plates and permits communication between the first outlet and the outlet openings.
