▎ 摘　　要

NOVELTY - Graphene heat-dissipating film based on graphene material comprises a heat dissipation unit (2) and a shell (6). The bottom of the shell is provided with a nano-carbon thermal conductive layer (1). The two ends of the nanocarbon heat conducting layer are connected to the sides of the inner ends of the casing. The heat dissipation unit includes a first graphene heat dissipation layer (21), a second graphene heat dissipation layer (22), a heat dissipation copper tube, and a heat conductive copper sheet. The first graphene heat dissipation layer is disposed on an upper surface of the nanocarbon thermal conduction layer. The two ends of the first graphene heat dissipation layer are fixedly connected to the sides of the inner ends of the shell. The upper surface of the first graphene heat dissipation layer is provided with a polymer radiation prevention layer. Both ends of the polymer radiation protection layer are fixedly connected to the sides of the inner ends of the shell. USE - Used as graphene heat-dissipating film based on graphene material. ADVANTAGE - The film: quickly dissipate the heat transferred from the inside of the mobile phone to the back cover, and has excellent heat-dissipating effect, prevents the temperature of the mobile phone from being too high and affecting the user experience, and also prevents radiation and anti-static. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene heat-dissipating film based on graphene material.
