Cooling Characteristics of Heat Conduction Sheet for a Mobile Device

(Experiment with inside sheet model)

Abstract

Mobile devices are becoming more functional, thinner and having waterproof function. Therefore, heat is easily stored inside a mobile device. As a solution to the problem, heat conduction sheet was developed, but its optimum setup is not sure. In this situation, a simple analysis model had been proposed for heat conduction sheet and its numerical prediction was verified with experiments only in case of the outside sheet model. However, the heat conduction sheet becomes installed inside of late. In this report, heat transfer effect was compared between outside and inside sheets using the simple analysis model, and an experiment with inside was conducted.
