Abstract :
In this paper, a phase change material (PCM) based heat sink was proposed and its geometry was optimized for heat transfer enhancement. The thermal resistance network between the heat source and the control volume was applied to analyze the influence on heat storage performance of the phase change material based heat sink (PCMBHS) and the optimization suggestions were proposed. Besides, the heat storage performance of the optimized fined PCMBHS was examined experimentally. The results showed that the temperature difference of the PCM inside each control volume reduced by 67% and the heat storage rate increased by 14% compared to those of the uniformly fined PCMBHS during the latent heat storage period.
