▎ 摘 要
NOVELTY - The utility model claims a composite graphene oriented radiating film and electronic device, the composite graphene oriented radiating film comprises orderly laminated insulating layer, graphene layer and metal foil layer, the graphene layer has at least one edge opposite to the insulating layer of the convex area, the area is contacted with the heat source of the electronic device. the graphene layer is provided with a relatively insulating layer at least one edge convex area; and the area is contacted with the heat source; after the heat source generates heat, the heat is directly conducted to the graphene layer and diffuses along the transverse and longitudinal direction of the graphene layer. In the longitudinal direction, the heat part of the graphene layer is transmitted to the metal foil layer, diffusing to the outside, the other part of heat is transferred to the heat insulating layer, because the heat insulating layer cannot transfer heat, the heat is formed; the enriched heat is transmitted to the graphene layer by the heat insulating layer under the action of heat gradient, and finally radiated to the outside through the metal foil layer. .
