Abstract

A plate for the use in a heat exchanger cassette, where the plate comprises a corrugated pattern having a plurality of ridges (9) and valleys (10), and where the plate comprises a sealing gasket groove (3) encircling a heat transfer surface (8) that will be part of a contact-free fluid channel when two cassettes comprising at least one plate each are positioned adjacent each other, wherein the sealing gasket groove (3) comprises a base surface with a first, flat section (12) and a second, bent section (13), and where the bent section is angled with the angle α. The advantage of the inventive plate is that an airtight heat exchanger cassette can be obtained in an easy and cost-effective way.
