Heat sink, preparation method therefor, and communications device |
| abstract |
A heat sink, which includes a first surface and a second surface opposite to the first surface, where the second surface includes a plurality of sub-surfaces, and each sub-surface is configured to be in contact with a surface of a heat emitting element; the plurality of sub-surfaces include a first sub-surface, a thickness between the first sub-surface and the first surface is less than a thickness between the first surface and each of the plurality of sub-surfaces except the first sub-surface; and the heat sink includes a plurality of layers of graphene sheets, each layer of graphene sheet includes a plurality of flake graphite particles, and two adjacent flake graphite particles located in a same layer of graphene sheet are covalently bonded. |
