A plate heat exchanger gasket includes an elongate body and a first number of elongate projections projecting from an upper side of the body and extending along the gasket's longitudinal extension. Each projection is defined by a top and two opposing flanks extending from the top. Referring to a cross section perpendicular to the gasket longitudinal extension, for each of a second number of unsymmetrical projections of the projections, a first area defined by an outer flank of the flanks, the body upper side and a normal of the body upper side extending through the top of the unsymmetrical projection, is smaller than a second area defined by an inner flank of the flanks, the body upper side and the normal of the body upper side extending through the top of the unsymmetrical projection. This normal is displaced from a center normal of the body upper side.

A heat exchange plate for a plate heat exchanger, and a plate heat exchanger having the heat exchange plate. The heat exchange plate includes: a heat exchange plate body; and a ring-shaped flange projecting obliquely from an edge of the heat exchange plate body. The flange has a protrusion having a reinforcing action. The heat exchange plate and plate heat exchanger according to embodiments of the present invention can, for example, improve the quality of the heat exchange plate of the heat exchanger.

A plate kind heat exchanger (1) has a plurality of stacked plates (2) forming flow paths for heat exchanging fluids there between, a first inlet channel being fluidly connected to inlets of a first set of flow paths, a second inlet channel being fluidly connected to inlets of a second set of flow paths, a first outlet channel being fluidly connected to outlets of the first set of flow paths, and a second outlet channel being fluidly connected to outlets of the second set of flow paths. The first inlet channel is provided with a stack (15) of rings (5) forming fluid passages towards the inlets of the first set of flow paths. Each ring (5) has a first rigid shell member (6) and a second rigid shell member (7), the first rigid shell member (6) and/or the second rigid shell member (7) defining a groove (9) providing fluid passage from the first inlet channel to one of the flow paths of the first set of flow paths, and a sealing member (8) formed from a compressible material, the sealing member (8) being positioned between the first rigid shell member (6) and the second rigid shell member (7). The stack of rings (15) is subjected to a force which presses the rings (5) towards each other and compresses the sealing members (8) of the rings (5), thereby providing sealing towards the flow paths of the second set of flow paths.
