GASKET ARRANGEMENT, HEAT TRANSFER PLATE, KIT, ASSEMBLY, HEAT EXCHANGER AND METHOD
The present invention relates to a gasket arrangement for sealing between two corrugated heat transfer plates of a plate heat exchanger. The heat transfer plates each comprising a pair of port holes. The gasket arrangement comprising an annular sealing part being arranged to enclose the pair of portholes of the heat transfer plates and define a flow path between the port holes of the pair of port holes. The gasket arrangement further comprising an attachment part connected to an inside of the annular sealing part and extending in an inwards direction relative to the annular sealing part. The attachment part defining a gasket attachment surface arranged to attach by an adhesive to a corresponding plate attachment surface of one of the heat transfer plates.
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.
