The utility model relates to a plate sheet sealing structure of a plate heat exchanger, which comprises a sealing gasket and a sealing groove on a plate sheet, two sealing strips are arranged on the corner hole and the periphery of the sealing gasket, the two sealing strips are locally connected, grooves are arranged at the positions of the sealing groove on the plate sheet, which correspond to the sealing strips and the sealing strip connecting position, and the sealing strips are arranged in the grooves. Protrusions are arranged at the positions, corresponding to the hollowed-out positions between the two sealing strips, of the sealing grooves in the plate piece, T-shaped hooks are arranged on the outer sides of the sealing strips, and hook grooves are formed in the positions, corresponding to the T-shaped hooks, of the plate piece. The plate sheet sealing structure adopts a double-channel sealing mode, is better in sealing effect, solves the problems that after the heat exchanger is installed, water leaks
