AB - 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.
