Thermal performance of PCM-cooled mobile phone

This paper presents the experimental study of using phase change material (PCM) in the cooling of the mobile phone. It investigates the thermal performance of transient charging and discharging of mobile phone in three different situations; making phone calls frequently, making long duration calls and making occasional calls. The results show that mobile phones are heated up fastest during the long duration usage. Experiments are also conducted to determine the effect of fins and effect of orientation of the mobile phone on its thermal performance.
