Abstract
The invention provides a shell of terminal equipment and a processing method of the shell. The shell comprises a shell body and a heat conduction layer sprayed on a surface of the shell body, whereinnano carbon particles and heat conduction metal particles are contained in the heat conduction layer, and a surface of the heat conduction layer is provided with an uneven heat dissipation microstructure. The nano carbon particles have excellent heat conduction and heat radiation performance, the heat conduction performance is mainly reflected in heat diffusion transfer, the heat diffusion speed of the nano carbon particles is larger than or equal to 200 mm<2>/S, a heat radiation coefficient is 0.92-0.95, the nano carbon particles have excellent heat conduction performance, moreover, the carbon nanoparticles can form a continuous heat conduction channel on the surface of the shell after being dried, so heat conduction performance can be enhanced, and the heat can be conducted out more quickly. The particle size of the heat conduction metal particles is large, the nano carbon particles and the heat conduction metal particles can form the uneven heat dissipation microstructure on the surface of the shell body, the heat radiation area can be increased, and thereby heat dissipation performance of the heat conduction layer is further improved.
Description
technical field [0001] The present disclosure relates to the technical field of heat dissipation, and in particular to a housing of a terminal device and a processing method thereof. Background technique [0002] At present, the emergence of large-scale integrated circuits has promoted the development of the intelligent terminal industry. At the same time, the increasing density of electronic components, the thinning of smart terminals and the compactness of packaging technology have made effective thermal management very difficult, and local overheating problems will occur when smart terminals work for a long time. [0003] At present, the common heat dissipation methods include attaching heat dissipation film, thermal silica gel and copper plating, etc. Among them, the method of copper plating can form a dense and smooth copper layer on the terminal shell, which has good thermal conductivity and It can be closely attached to the terminal shell, thereby promoting the heat ...
