ABSTRACT:
In this study, we numerically investigated the heat removal effectiveness of various phase change materials (PCMs) when injected into a plate-fin heatsink with a fixed thermal conductivity enhancer (TCE) volume fraction of 9%. This study focuses on examining the effects of fin numbers and PCM types. The numerical simulation, using ANSYS commercial software, shows that the performance of the PCMinfused heatsink has improved as the number of fins increases. When a plate-fin heatsink soaked in paraffin wax and exposed to a heat-flow density of 4 kW/m2 for 30 minutes, the maximum temperature did not exceed 70°C for the 4-fin design but it exceeded 80°C for the 0- and 2-fin design. The salt hydrate PCM has shown superior performance when compared to paraffin wax and RT35. The zero-fin model has taken double the time required to melt all the PCM when compared to 2- and 4- fin heatsinks.
