Summary
The ability to dissipate large amounts of heat from small surface areas is important in designing many advanced electronic devices because effective thermal management is essential in maintaining the performance of these devices. A phase change material (PCM)-based cooling system that utilizes passive cooling can dissipate heat effectively using phase change (i.e., latent heat of PCM) with a small volume change during melting and solidification. The heat transfer performance can be improved by using the heat sink owing to the high thermal conductivity of internal metal fins. The thermal performance of PCM-based heat sinks for various design parameters was numerically investigated. A numerical model was constructed to simulate the melting and solidification of PCM by Shatikian et al[1] the effects of various fin heights and thicknesses of PCM-based heat sinks were investigated for constant temperature and heat flux conditions.[2,3] The dimensional analysis of the results shows that the melt fraction and Nusselt number depend on the combination of the Fourier, modified Stefan and Rayleigh numbers. Wang et al numerically studied the effects of the orientation of the heat sinks on the ISSN 0914-4935 © MYU K.K. https://myukk.org/
