Research on thermal design of smart phone terminal product

In order to solve the local overheating problems existing in intelligent mobile terminal, starting from the plane layout area, the heat conduction technology is adopted to catch the key of heat source device layout for multimode intelligent mobile terminal. The minimum layout area, taking account of heat dissipation, was obtained. The height of the complete machine structure was calculated according to heat flux density. The layout and structure design were simulated through thermal simulation technology. A reference comment about structure design is givenb in this paper. The test is performed to verify and improve the thermal design. The beating infrared spectrum distribution test was applied to an actual product. The temperature distribution plan of intelligent mobile products was obtained. A conclusion which was in keeping with simulation was obtained.
