Sealing gasket limiting structure for heat exchanger

The invention discloses a sealing gasket limiting structure for a heat exchanger, and relates to the technical field of plate heat exchangers, the limiting structure comprises a plate sheet, the front end of the plate sheet is connected with a sealing gasket in an embedded manner; the limiting frame is hinged to the plate sheet and can cover the outer part of the sealing gasket; wherein a clamping groove is formed in the outer portion of the limiting frame, the extending direction of the clamping groove is consistent with the shape of the limiting frame, when the limiting frame covers the outer portion of the sealing gasket, the sealing gasket is embedded in the clamping groove, and the upper face and the lower face of the sealing gasket both extend to the outer portion of the clamping groove. According to the sealing gasket limiting structure for the heat exchanger, due to the fact that the limiting frame with the clamping grooves is adopted to cover the sealing gasket, the technical problem that when an exi
