TRANSIENT AND CYCLIC EFFECTS ON A PCM-COOLED MOBILE DEVICE

ABSTRACT
A mock handset with heat storage unit (HSU) has been designed, fabricated, and experimented under various conditions to examine the effect of external heat sink on the handset’s transient temperature distribution, performance of the individual HSU under different power level and orientation, as well as under the more realistic cyclic heating. The cooling of the handset is through using a phase change material (PCM), n-eicosane, stored in the external HSU connected to the handset through a miniature heat pipe. The heat pipe channels the internal heat dissipation to the HSU where it is absorbed by the PCM. Results show that the temperature is significantly lowered with the PCM-based HSU.
