Abstract

In a three circuit plate heat exchanger stacked plates (31-36) forming channels for two flows (y, z) of fluid which should exchange heat with a third fluid (x) are each comprising two plate areas (20) surrounding two port forming holes and four plate areas (50) surrounding four port forming holes. The said two plate areas (20) surrounding two of the port holes are displaced through a vertical distance (H) away from the areas (50) surrounding four of the port forming holes. All channel forming plates are provided with a pressed pattern the maximum pressed depth of which is=h=about H/2.
