▎ 摘　　要

NOVELTY - Protective shell, comprises a shell (1), and a radiating module (4) set in the shell. One side is attached with the inner side of the shell bottom plate, and the other side contacts the battery cover of the mobile phone. The radiating module comprises graphene composite film (7), and a phase change plate (9) made of phase change material. The graphene composite film contacts the battery cover and absorbs the heat from the battery cover, and then transmits the heat to the phase change plate located on the graphene of the film. USE - The protective shell is useful in mobile phone for cooling device. ADVANTAGE - The shell is matched with phase change layer and graphene, achieves potential storage and release, significantly improves the terminal user experience, economic value and production efficiency, and reduces cost. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional structural schematic diagram of the graphene composite phase change material of mobile protective shell. 1Shell 7Graphene composite film 8First adhesive layer 9Multi-layer phase change plate 10Second adhesive layer
