Abstract:
1. A heat exchanger plate for a plate heat exchanger, the heat exchanger plate comprising: a number of ports, distribution regions, adiabatic regions, a heat transfer region, and an edge region which extends outside the number of ports and also extends outside said distribution regions, the adiabatic regions and the heat transfer region, whereby the heat exchanger plate includes a gasket groove in the edge region outside said distribution regions, the adiabatic regions and the heat transfer region and around the number of ports, the gasket groove extending longitudinally along two opposite sides of the heat transfer region, whereby the gasket groove is configured to accommodate a gasket for sealing abutment against an adjacent heat exchanger plate in the plate heat exchanger, at least two portions of the gasket groove along each side of the heat transfer region being recessed toward the heat transfer region, which two recessed portions are separated by an intermediate portion, a longitudinal extent of each of said two recessed portions being less than a longitudinal extent of the intermediate portion, the edge region being provided, at the at least two portions of the gasket groove, with a corrugation pattern of ridges and valleys arranged to engage a clip-on tab comprised in the gasket to securely fasten the gasket to the heat exchanger plate.
