Numerical study on the performance of Al2O3/water nanofluids as a coolant in the fin channel heat sink for an electronic device cooling

Abstract

This research analysis is a numerical examination of a fin channel heatsink using coolants Al2O3/water nanofluids and distilled water. Because of its high thermal conductivity and stable character, Al2O3 has been the subject of recent research. Literature has also shown that compared to other nanoparticles Alumina has the lowest rate of precipitation and the most reliable emulsification. The channel finned heat sink with fins is widely used to dissipate heat from tiny electronic components. In this research, the heat transmission properties, thermal resistance, and Nusselt number of Al2O3/water nanofluids were studied using inlet velocities, and different volume concentrations in the heat sink and then compared the results with the distilled water performances. To examine the effectiveness of the fin channel heat sinks the ANSYS-CFX software is used. The consequences show a maximum improvement of 68% heat transfer coefficient at inlet velocity range from 0.02 m/sto0.10 m/s and at different boundary conditions. Furthermore, the thermal resistance of the (Al2O3/water) nanofluids is much lower than distilled water and hence it is used to reduce the temperature.
