FIELD: heat exchangers with flat plates, as well as their gaskets. ^ SUBSTANCE: the gasket designed for use in a heat-exchange device, having heat-exchange plates provided with the first and second sides, edge and a groove located on its first side and passing along the edge at a certain distance from it, includes: the elongated main part placed in the groove and sealing the connections between the mentioned first and second heat-exchange plates when the mentioned second heat-exchange plate is held pressed to the first plate; and at least one part of the plate seizure that includes at least one coupling member coming in engagement with the part of the plate on its first side, the mentioned coupling member is made integral with the mentioned coupling member is made integral with the mentioned main part of the gasket, breaks away from it in the transverse direction, crosses the plate edge and has a free end; and at least one claw connected to the mentioned free end of each mentioned coupling member by means of a hinged joint and made so that it can be bent relative to the mentioned coupling member for giving it such a position in which it engages the second side of a definite part of the plate. Besides, the claw has an initial, non-operating position in which it is inclined at a definite angle relative to the mentioned coupling member, and the mentioned hinged joint acts in such a manner that each mentioned claw can be turned and bent, bringing it from the mentioned non-operating position to a position, in which it gets engaged with the second side of the plate part under the action of the force with which the mentioned claw strives for return to its non-operating position. The invention makes it possible to produce a gasket in a plate heat-exchange device, which has clamping members for application to the heat exchanger plate of a considerable clamping force in the transverse direction so as to provide a reliable retention of the gasket on the plate in the necessary position before compression of the unit. ^ EFFECT: enhanced reliability. ^ 24 cl, 41 dwg |
