Abstract: The present application relates to the field of electronic product heat dissipation component and in particular, relates to a graphene thermally conductive gasket edge-wrapped process and an edge-wrapped graphene thermally conductive gasket. The process steps are: coating a layer of adhesive on the first layer of graphene film, placing the second layer of graphene film on the first layer of graphene film, repeating stacking to the target height, obtaining a graphene film block, punching a plurality of through holes penetrating two surfaces of the graphene film block; threading the carbon fiber through the through holes after coating an adhesive on the surface thereof; slicing along the direction parallel to the thickness direction of the graphene film, to obtain the graphene thermally conductive gasket with a specified thickness; and coating a layer of glue on the peripheral sides of the graphene thermally conductive gasket to form an edge-wrapped layer.

Abstract: A composite server heat sink with a metal base having a thermal conductivity of at least 200W/mK. Plural fins extend from the metal base, each fin having an anisotropic thermal conductivity in a range of approximately 300 to 650 W/mK in a longitudinal direction of the fin and less than approximately 30 W/mK in a widthwise direction of the fin. Each fin includes graphite in an amount of approximately 45-70 wt. %, diamond in an amount of approximately 2.5 to 10 wt. % with the balance comprising a metal selected from one or more of copper and aluminum. To create the anisotropic thermal properties, the graphite is aligned along the longitudinal direction of the fin.
