Abstract: A brazed plate heat exchanger comprises alternating first and second heat exchanger plates each having two long side edges, two short side edges and a longitudinal axis parallel to the long side edges. Each first and second plate has a corrugation pattern forming a heat transfer area comprising mutually parallel ridges and grooves in which the ridges of one first plate abut the grooves of an adjoining second plate. Each ridge and groove of at least one first heat transfer area of each first late is inclined between 0° and 30° relative to the longitudinal axis. Each ridge and groove of at least one heat transfer area of each second plate is inclined between 90° and 45° relative to the longitudinal axis.

Abstract: A heat exchanger plate for the use in a three circuit heat exchanger assembly, where the plate comprises a first distribution area, a heat exchange area and a second distribution area, where the plate comprises a corrugated pattern having ridges and valleys, and where the central port hole in the first distribution area is positioned at a vertical distance from the short end of the plate such that a fluid passage is obtainable between the central port hole and the short end of the plate when two plates are stacked to form a fluid channel between the plates. The invention further relates to an assembly made from such heat exchanger plates and a heat exchanger comprising a plurality of such assemblies. The advantage of the invention is that an improved heat exchanger is provided, having an increased thermal performance and an improved flow distribution in the heat exchanger.
