A plate heat exchanger comprises a plurality of heat exchanger plates (1) formed of a metal sheet and permanently joined to each other by means of a braze material to form a plate package having first plate inter spaces (4) and second plate inter spaces (5). Each heat exchanger plate has a pattern forming a heat transfer area and a plurality of porthole areas. Each heat exchanger plate extends along a main extension plane (p). The areas extend, on one side of the heat exchanger plate, between a primary level (p') at a distance from the main extension plane and a secondary level (p') at a distance from and on an opposite side of the main extension plane. Each heat exchanger plate has a depth (d) defined by the distance between the primary level and the secondary level. The depth is equal to or less than 1,0 mm.
