Abstract
A porthole gasket to be installed between a corrugated first plate and a second plate of a heat exchanger such that a central extension plane of the gasket is parallel to the first and second plates is annular and arranged to enclose, within the gasket inner periphery, porthole areas of the first and second plates. A first surface of the gasket, configured to engage the first plate, is corrugated to define alternately arranged gasket ridges and gasket valleys along a longitudinal extension of the gasket. The ridges and valleys mate with plate valleys and plate ridges, respectively, of the first plate. A second surface of the gasket, configured to engage a plate arrangement comprising the second plate, is essentially plane and arranged to contact an essentially plane surface of the plate arrangement. The ridges protrude, and the valleys descend, in a normal direction of the central extension plane.
