Abstract

A heat exchanger plate (1) for a plate heat exchanger for heat exchange between at least a first fluid and a second fluid, the heat exchanger plate (1) having a quadrilateral shape with two opposite parallel primary sides (5) and two opposite parallel secondary sides (6), and a longitudinal central axis (x) being parallel with the primary sides (5). The heat exchanger plate (1) comprising a heat exchanging area having a corrugation of ridges and valleys having a longitudinal extension defining an inclination in relation to the longitudinal central axis (x), four portholes (11, 12, 13, 14), of which at least two are located at a respective corner of the heat exchanger plate (1) extending through the heat exchanger plate (1), a first set of ridges (8a) and valleys (9a) and a second set of ridges (8b) and valleys (9b), wherein the longitudinal extension of the first set of ridges and valleys (8a, 9a) define a first angle (α) in relation to a first primary side (5a) and the longitudinal extension of the second set of ridges and valleys (8b, 9b) define a second angle (β) in relation to a second primary side (5b), wherein an intersection between the first set of ridges and valleys (8a, 9a) and the second set of ridges and valleys (8b, 9b) being defined as a transition area (10) comprising a curvature of ridges and valleys being concentric with a porthole.
