Abstract
The present invention is a plate heat exchanger for heat transfer between two fluids, having several thin heat transfer plates (1) abutting towards each other and between the heat transfer plates (1) arranged sealing members (6), which in alternate plate interspaces delimit a flow space for a first fluid and in the remaining plate interspaces delimit flow spaces for a second fluid, each heat transfer plate (1) having a pressed corrugation pattern, which has two distribution portions (7, 8) and, arranged between these, a main heat transfer portion (9), which is divided in several areas (10a, 10b) with parallel ridges and valleys, and the plate heat exchanger having inlets and outlets for the fluids, arranged such that the fluids will have a flow direction between the heat transfer plates (1) essentially from one to the other of the distribution portions (7, 8) at each heat transfer plate. According to the invention the heat transfer portion (9) of each heat transfer plate (1) has a row with at least three areas (10a, 10b) located after each other in the flow direction and an even number of such rows are arranged next to each other across the flow direction, by which the parallel rid…
