NOVELTY - The utility model claims a heat dissipation structure technology field, specifically claims a new-type composite heat dissipation material, comprising copper-aluminium composite board, graphite heat dissipation layer adhered to one surface of the copper-aluminium composite board laminating layer, provided on the adhesion layer face. the copper-aluminium composite board comprises copper foil layer and the foil, the copper foil layer and the aluminium foil layer is metallurgical composite are connected to form a whole, the copper foil layer and the jointing layer; this utility model solves the problem that the heat dissipation plate heat conducting performance is insufficient, the heat dissipation effect is not enough. adopting the structure for heat dissipation copper-aluminium composite plate is combined with graphene, the graphene fast heat conducting combination of copper-aluminium composite heat dissipation, high heat conductivity, good heat dissipation effect.
