Numerical Thermal Analysis of Nano Fluid Based Heat Pipe for Electronic Devices

Abstract

An analytical and numerical model is developed for heat pipe having Magnesium Oxide Nano fluids of concentration 0.5, 1.0 & 1.5%. Heat pipe with the induction of Nano fluids are becoming the preferred choice as a heat sink in electronic devices. These heat pipes are being used due to their higher thermal conductivity, compact design and enhanced life with better efficiency. This study has numerically and experimentally investigated the thermal analysis and thermal management by the induction of Magnesium Oxide (MgO / water) Nano fluids in sintered wick heat pipe. The analytical model is developed with suitable assumptions. The ANSYS FLUENT software has been used for numerical analysis. A comparison of analytical modeling determines the temperature profile result shows that the analytical modelling and numerical modeling results are in good range with the numerical modeling results. There is less than 5% error in both results.
