NOVELTY - The utility model claims a radiating fin device of graphene, comprising a radiating channel, wherein the radiating channel outer wall is connected with a graphene radiating layer; the radiating channel is provided with a cylindrical cavity; the radiating channel is connected with the cylindrical cavity through the aluminium plate, the cylindrical cavity is provided with a low boiling point solvent in the interval 39-61 the top end of the cylindrical cavity is provided with a channel connected with the movable cavity; the movable cavity is provided with a screw rod and a piston block; a spring is connected between the piston block and the cylindrical cavity; one end of the screw rod far away from the piston block passes through the movable cavity and is fixedly connected with several fan blades. The utility model does not need power, using heat airflow heat and low boiling point solvent to drive the fan blade to rotate to drive the air to accelerate, accelerating the progress of heat dissipation, and increasing the contact area with the hot air by the graphene layer distributed in the wave line type, convenient for accelerating the heat dissipation of the radiator, improving the radiating effect, simple and practical.
