Employing Al2O3 And MWCNT Water Nanofluids To Improve The Thermal Performance Of Varied Flow Configuration Heat Sinks For Electronic Cooling: An Experimental Evaluation

Abstract

This research investigates the uses of nano fluids with an emphasis on its distinctive thermal characteristics & its potential to increase systems' heat transfer effectiveness. One important factor which affects a fluid's capacity to transport heat is its thermal conductivity. Moreover, the size, shape, & concentration of nanoparticles are among the elements that this research looks at in order to determine how well nanofluids transport heat. This study looks at the possibility of employing nano fluids to improve heat transfer during the cooling of electronic equipment. The research's results indicate that MWCNT/water nanofluids has a substantially higher thermal conductivity than Al2O3/water Nanofluid, and this leads to the conclusion that MWCNT/water Nanofluid has a higher heat transfer coefficient than Al2O3/water nanofluids. Al2O3/water Nanofluid& MWCNT/water nanofluids at volumes concentrations of 0.1% & 0.7%, respectively, had similar coefficients of heat transfer. The coefficient of heat transmission while using MWCNT/water Nanofluids is much greater than when using Al2O3/water Nanofluids. Due to the increased thermal conductance of MWCNT nanoparticles comparing to Al2O3 nanoparticles, heat transfer coefficients was found to be greater in MWCNT/water Nano fluids at 0.1%, 0.3%, 0.5%, & 0.7% vol. concentrations for all 3 tests sections. Moreover, the heat transfer coefficients rise as the test section's diameter decreases.
