NOVELTY - The utility model claims a heat exchange plate for plate heat exchange type graphene electric heater, relating to the technical field of heat exchanger, comprising a first region and a second region, the first region and the second region in graphene heating film thickness are different, the two regions generate different heat, namely can obtain two different heat flow region; the concave-convex block can make the heat exchange plate form a plurality of turbulent flow area, increasing the flow of the water, slowing the flow speed of the water; the long strip-shaped turbulent flow bump can form a heat flow area; the strip-shaped groove can form a cold flow area; the groove track can be set with graphene heating film; the graphene heating film is connected with the electric heating to generate heat flow; The device of the device increases the space between the convex support groups in the heat exchange plate sheet, so that the containing water flow is increased, so that the flow rate of the hot water flow is increased; the heat is increased, and the heating effect of the electric heater is increased.
