NOVELTY - The utility model claims a graphene radiation copper foil, comprising orderly installed from top to bottom of the graphene, the ultrathin copper layer, heat-conducting silica gel layer, copper base layer, a release layer and an adhesive layer, the utility model of the ultrathin copper layer is provided with plurality of projections increases the outer surface area of the copper foil, the top end face is coated with graphene, this structure makes the copper foil and external heat exchange efficiency is obviously improved, ultra-thin copper layer and the copper base layer are locked through the fixed lug boss and fixed groove, the gap between them is filled with heat conducting silica gel layer; and heat-conducting silica gel layer fill the concave hole, on one hand, this structure improved the ductility and toughness of the ultra-thin copper layer and the copper base layer, fixed lug boss and fixed groove and also has the function of reinforcing rib, making it not easily broken but does not increase too much hard, on the other hand, ultra-thin copper layer and the copper base layer is set between the heat-conducting silica gel layer compared with the traditional single copper foil on the conductivity is remarkably improved.
