A graphene electronic component water cooling plate comprises a bottom plate, a cover plate, inner fins, a graphene coating and a water inlet and outlet, the bottom plate and the cover plate form a sealed cavity, the edge of the cavity is provided with the water inlet and outlet for a cooling medium to enter and exit the cavity, the fins are arranged in the cavity, and the bottom surface of the bottom plate is provided with a thermal contact surface and a thermal auxiliary surface. Wherein a boss serving as a thermal contact surface of the electronic element is punched on the bottom surface ofthe bottom plate, the bottoms of the other bottom plates without the punched boss are thermal auxiliary surfaces, the thermal contact surface and the thermal auxiliary surfaces of the bottom plate are coated with graphene coatings, and a mounting hole for fixing the electronic element is formed in the water cooling plate. By adopting the electronic component water-cooling plate, the problem thatthe heat dissipation of th
