Abstract
A plate heat exchanger includes a plurality of heat exchanger plates 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 interspaces and second plate interspaces. 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. The areas extend, on one side of the heat exchanger plate, between a primary level at a distance from the main extension plane and a secondary level at a distance from and on an opposite side of the main extension plane. Each heat exchanger plate has a depth defined by the distance between the primary level and the secondary level. The depth is equal to or less than 1.0 mm.
