Abstract
As smart phones become more complex, higher in performance and smaller in size, heat concentration at localized areas is becoming a problem. Phase change materials (PCM) have drawn attention as passive thermal management. In this study, simple experiments using PCM were conducted. The results showed that the saturation time increased with increase in the mass of PCM, and a relationship between the saturation time and the mass of PCM was a linear relation. Furthermore, the saturation time increased with decrease in the melting temperature of PCM. As a result, PCM is effective for the thermal management of smart phones.
