Abstract
A plate heat exchanger (1) comprises a stack of heat transfer plates (2) provided between two end pieces (3, 4) and each having an essentially plane extension. Each end piece (3, 4) has an inner surface (9) facing said heat transfer plates and an outer surface (14) facing away from said heat transfer plates (2) and extending from one side to another of the end piece (3, 4). The plate heat exchanger (1) is compressed by means of at least one member (18) extending around the plate heat exchanger and abutting said outer surface (14) of each end piece (3, 4) in order to prevent the retreat of the end pieces from each other. The outer surface (14) of each end piece (3, 4) is curved in such a manner that the end piece has a convex shape in a cross section along a first plane (Y, Z) being perpendicular to the essentially plane extension of the heat transfer plate (2).
