Abstract
In this research, the performance of a finned heat sink with phase change material (PCM) is numerically simulated for two cases: with and without PCM. The results showed an improvement in heat sink performance when using PCM. One of the defects of PCMs is their low thermal conductivity. One solution to deal with this problem is the addition of high thermal conductivity nanoparticles to PCMs. For this purpose, the effects of adding copper oxide and aluminum oxide nanoparticles to paraffin PCMs were investigated. The results show that the performance of heat sink is improved by adding a low percentage of nanoparticles (2%). However, by increasing volume fraction of nanoparticles to 6%, not only the heatsink performance does not improve, but also decreases.
