NOVELTY - The utility model claims a radiating type metal base, the metal base, comprising a base, a filling block, a substrate. the filling block is filled in the groove, and the top end of the filling block is flush with the upper edge of the groove or adhered to the inner side surface of the groove for setting, and the depth of the groove is less than the thickness of the base. the substrate is a rectangular plate with a plurality of filling blocks on the surface, and the filling block and the substrate are graphene of material. The groove of the radiating type metal base of the utility model is filled with graphene filling block, using the heat resistance and good plasticity of the characteristics, using metal base and the base graphene heat dissipation, improving the efficiency of the base heat dissipation. In addition, after connecting component, avoiding damage caused by overheating of the component. using the filling block to form a net-shaped structure in the groove, strengthening the metal base contact out passive heat dissipation. The heat conduction efficiency is increased.
