Embodiment Construction

[0027] Figures 1 and 2 show a plate heat exchanger 1 comprising a plate assembly 2 with heat exchanger plates 3 arranged adjacent to each other. This plate assembly is arranged between two end plates 4 and 5 . The end plates 4 and 5 are pressed against the plate assembly 2 and against each other by means of tension bolts 6 which extend through the end plates 4 and 5 . The tension bolt 6 comprises a thread, and thus the plate assembly 2 can be compressed by screwing a nut 7 onto the tension bolt 6 in a manner known in the art. In the illustrated embodiment, four tension bolts 6 are shown. It should be noted that the number of tension bolts may vary and may be different in different applications.

[0028] The plate heat exchanger 1 also comprises two inlet pieces 8 and two outlet pieces 9 . The inlet piece 8 and the outlet piece 9 extend through one of the end plates 5 and the plate assembly 3 . Plate 3 is provided with openings 10 in a manner known in the art, see image 3 ...

Abstract

The invention relates to a heat exchanger plate ( 3 ), a plate heat exchanger with a plate package of heat exchanger plates and a method for manufacturing a heat exchanger plate. The heat exchanger plate includes a heat transfer area ( 20 ) and a border area ( 22 ), which is located outside the heat transfer area and which extends along and delimits the heat transfer area. A curable polymer material is applied to the border area in such a way that it extends along the whole or parts of the border area. The polymer material forms after curing a gasket ( 30 ) for tight abutment against an adjacent plate in the plate heat exchanger.

Description

technical field [0001] The invention relates to a heat exchanger plate for a heat exchanger, wherein the plate comprises a heat transfer area and a border area, which is located outside the heat transfer area and extends along the heat transfer area and defines the heat transfer area borders. The invention also relates to a plate heat exchanger comprising a plurality of such plates. In addition, the invention also relates to a method of manufacturing a heat exchanger plate, comprising the steps of providing a thin plate, cutting the plate and forming the plate into a heat exchanger plate with a heat transfer area and a boundary area, the heat transfer area The area has a large number of openings, the boundary area is located outside the heat transfer area and extends along the heat transfer area and defines the boundary of the heat transfer area. Background technique [0002] SE-B-548806 discloses a plate heat exchanger with such heat exchanger plates. The heat exchanger ...
