NOVELTY - The utility model claims a graphene heat sink. it comprises a substrate and a base plate arranged on the radiating fin, the surface of the base plate and a radiating fin attached with a graphene coating by way of spraying or electroplating, on the substrate equipped with electronic component, electronic component in direct contact with the surface of the base plate and the heat through the graphene coating on the whole piece of substrate, the heat conducting substrate can be stored and conducted to the radiating fins to radiate. after adopting said structure, reduces the product volume, reduces the space occupation, reduces the equipment cost, avoids the traditional refrigerant existing on or cold water leakage risk, ensures the durability of the component low use and maintenance cost, and on one hand, avoids the noise problem and does not need any cycle or power system auxiliary cooling can achieve very good radiating effect, simple and small whole structure design thereof, besides, the structure design can greatly improve the product surface anti-oxidation ability.
