Abstract
A heat exchanger is provided comprising a stack of heat exchanger plates (1, 1a, 1b, 1c) formed of sheet metal having a three-dimensional structured pattern (2, 3), each heat exchanger plate (1, 1a, 1b, 1c) having a groove (10), a gasket (9) being arranged in said groove (10) and resting against an adjacent heat exchanger plate (1a), said groove (10) having a bottom inner surface (11), said inner surfacebottom (11) having at least a protrusion (14, 15) directed to said adjacent heat exchanger plate (1a). It is intended to minimize the risk of a leakage. To this end in the region of said protrusion (14, 15) said gasket (9) is compressed more than in a region out of said protrusion (14, 15).
