A plate heat exchanger comprises several heat exchanger plates (1 ) provided beside each other, which form first plate interspaces (3) and second plate interspaces (4) in an alternating order. Every second heat exchanger plate forms a primary plate (V) and every second a secondary plate (1 "). Each heat exchanger plate extends in an extension plane (p) and comprises a heat transfer area and an edge area around the heat transfer area. The heat transfer area comprises a corrugation of ridges (30) and valleys (40), which each extends in a longitudinal direction. The ridges have two edge surfaces (31, 32) and a support surface (33) between the edge surfaces and with a first width (34) transversally to the longitudinal direction. The valleys have two edge surfaces (41, 42) and a support surface (43) between the edge surfaces and with a second width (44) transversally to the longitudinal direction. The support surface of the valleys of the primary plates slopes in relation to the extension plane and the support surface of the ridges of the secondary plates slopes in relation to the extension plane. |
