Claim:
1. A heat exchanger plate for a plate heat exchanger with a plurality of heat exchanger plates provided beside each other for forming first plate interspaces for a first medium and second plate interspaces for a second medium, wherein the heat exchanger plate extends in a main extension plane along a centre axis and comprises a heat transfer area and an edge area which extends around the heat transfer area, wherein the heat transfer area comprises a corrugation of ridges and valleys, which each extends in a longitudinal direction, wherein the ridges has a first edge surface, a second edge surface and a support surface, which extends between the first and second edge surfaces and has a first width transversally to the longitudinal direction, wherein the valleys has a first edge surface, a second edge surface and a support surface, which extends between the first and second edge surfaces and has a second width transversally to the longitudinal direction, wherein the support surface of the valleys slopes from the first edge surface of the valley to the second edge surface of the valley in relation to the extension plane at an inclination angle other than zero degrees, wherein the first edge surface of the ridge and the second edge surface of the ridge slope continuously upward from the main extension plane, and wherein the first edge surface of the valley and the second edge surface of the valley slope continuously downward from the main extension plane.
