▎ 摘　　要

NOVELTY - The film (2) has an outer layer being attached on a side portion of a heat absorption layer (23). A plastic base layer (11) is formed of polyethylene terephthalate. A heat diffusion layer is formed of a graphite sheet, a copper sheet, an aluminum sheet, a silver sheet and a graphene sheet. The heat absorption layer is formed of mix of paraffin, rubber and endothermic powder. The heat diffusion layer is sandwiched between the plastic base layer and the heat absorption layer, where the plastic base layer and the outer layer together fully cover an external portion of the heat diffusion layer and the heat absorption layer. USE - Heat dissipation film for use in a protective case (claimed) of a mobile device e.g. tablet and mobile phone. ADVANTAGE - The film utilizes a protective shell to cover a surface of a mobile device to enhance protective ability and structural strength of the mobile device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a protective case for a mobile device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a protective case for a mobile device. 2Heat dissipation film 10Protective case 11Plastic base layer 12Lens hole 23Heat absorption layer
