NOVELTY - The utility model claims a graphene composite radiating film, comprising an n-layer graphene film and m-layer worm graphite film; each layer of the vermicular graphite film is located between the two layers of graphene films; n is 2 to 5; m is less than n; the joint surface of the graphene film is provided with a buried hole structure; the buried hole is internally provided with worm graphite; The depth of the buried hole is 3 to 8 microns, and the diameter is 0.2 to 0.3cm. The utility model clamps the filling layer in the middle of the graphene film layer, so as to form an integrated structure; it has high heat conduction, low thermal resistance, low cost, controllable thickness, good flexibility and excellent thermal stability and so on; it is widely applied to the consumer electronics and communication; New energy automobile and large power LED field, so as to improve the radiating effect.
