When the sealing gasket is squeezed, the gasket body can be released by squeezing towards the concave parts on the two sides, so that the squeezing between the plates is reduced. The purpose of the trapezoidal plane boss arranged on the upper surface is to increase the contact stress between the center of the sealing gasket and the plate. The upper surface of the sealing gasket is extruded by the sealing groove of the upper plate, and the lower surface of the sealing gasket is matched with the sealing groove of the lower plate, so that the sealing gasket can be automatically positioned, and the sealing gasket is prevented from being misplaced or rolled. In addition, the sealing grooves on the heat exchange plates are arranged to be arc-shaped, so that the thinning rate of the sealing grooves of the heat exchange plates can be effectively reduced, and the problem that the sealing grooves of the heat exchange plates are extruded and deformed by sealing gaskets is solved. Meanwhile, a plurality of positioning parts are arranged on the outer edge of the sealing gasket body, each positioning part is composed of two symmetrically arranged lock catches and a trapezoidal snap fastener for connecting the two lock catches, the positioning parts are vertically connected with the center of the sealing gasket, clamping grooves matched with the lock catches and the trapezoidal snap fasteners are processed on the heat exchange plate, and when the heat exchange plate is installed, each positioning part is pressed in the corresponding clamping groove. The fixed effect of better realization of setting element and seal gasket combined action effectively improves the phenomenon that seal gasket takes place to misplace, roll even the play in the seal groove.
