Abstract (en)
A heat transfer plate for heat transfer apparatus, such as heat exchangers or evaporators is disclosed which is at least partially bounded by a groove (32) for receiving a gasket for general conformity therewith and to seal against an adjacent plate, wherein; the groove comprises an inner side wall and an outer side wall; the outer side wall of the groove is provided with a number of lateral bays (30), the gasket being formed with a number of corresponding spaced projections engaging in and matching with said bays; the base (33) of each bay is at a level other than the base (34) of the groove, and; each bay (30) does not communicate with the ambient thereby limiting movement of the gasket material along each said bay. The embodiments of the invention have a common feature that the gasket sealingly engages the rear wall (27). This engagement limits extrusion of the gasket material along the bay of the groove and thereby prevents <<blowing-out>> of the gasket at these points. Furthermore the floor of the bay, (40) is at a level other than the floor of the groove (42). This difference in level aids engagement between the gasket and the heat-transfer plate.
