NOVELTY - The utility model claims a diamond/graphene composite film, comprising a crystalline diamond film and the graphene layer of micron diamond film surface. diamond/graphene composite heat-conducting film of diamond and graphene bonding force is strong, and has a low interface thermal resistance between diamond and graphene is formed of graphene/diamond composite heat conducting film with high heat-conducting performance. The utility model further claims a radiating system. the radiating system comprises a heating element, a radiator and a heat conducting film, the thermally conductive film comprises said diamond/graphene composite film, the conduction between the heating element and the radiator, so that the heating element through the heat conducting heat to the radiator for radiating. the heat conducting film is rotatable independently from the heating element and the radiating element is present alone, it can pick up and stick, so it is easy for industrial production and use, at the same time, with excellent radiation performance.
