NOVELTY - A kind of cooling fin with graphene cushion layer, comprising fixing substrate and forming on the south and north bridge frame of upper substrate on the heat abstractor bracket, the cross section of said heat abstractor support for processing, on the uniformly formed with multiple radiating fins, then the substrate is three layer composite structure, graphene film layer in sequence as copper base layer and seat the south, wherein forming base layer on the copper and copper aluminum alloy layer forming on the graphene film on the layer, wherein graphene and graphene film layer and copper aluminum alloy layer between forming one layer heat abstractor with silicon resin or tin paste. This utility model new structure is compact, reasonable, assembly is easy, and can effective suitable forming notebook on the south and north bridge part for it to carry out heat abstractor.
