NOVELTY - The utility model claims a double-layer graphene heat conducting film, the heat conducting film from up to down comprises upper layer PET film, graphene heat conducting layer, heat conducting silica gel layer, graphene heat emitting layer, infrared reflecting layer; a lower layer of PET film; one side of the graphene heating layer is provided with an electrode strip; two ends of the electrode strip are extended to the outside of the heat conducting film through a lead and connected with a male joint and a female joint; the thickness of the graphene heat conducting layer is 50-200 mu m, the thickness of the graphene heating layer is 100-500 mu m. The double-layer graphene heat conducting film combines the heating thermal conductivity of graphene heating film and the infrared reflectivity of the infrared reflecting layer, so that the heat is better conducted, and the efficiency of heat conduction is improved.
