Abstract

The present invention refers to a plate heat exchanger for at least two heat exchanging fluids, which heat exchanger is permanently joined and comprises at least one core of plates with a plurality of inner heat exchanging plates (12b, 12c, 22b, 22c), at least two outer heat exchanging plates (12a, 22a, 22d) and at least two end plates (11, 21, 22). Each one of the heat exchanging plates (12a, 12b, 12c, 22a, 22b, 22c, 22d) is equipped with one or several corrugations vertically extending within an area bounded by two at a distance from each other situated parallel first and second planes respectively. The first plane is closer to a first end plate (11, 21) in one end of the heat exchanger than the second plane is. Each one of the heat exchanging plates is furthermore equipped with at least four port holes, every port hole being surrounded by a first sealing area, resulting in every heat exchanging plate showing at least four such first sealing areas. At least all except one of the mentioned first sealing areas on a first outer heat exchanging plate (12a, 22a) are in the mentioned first plane and bear on and seal against the mentioned first end plate (11, 21) extending in this plane.
