Thermal Performance of Loop Thermosyphon Charged by Nanofluid for Cooling Electronic Component

Abstract

In present work a experimental study based on thermosyphon is investigated using a solid nano-particles added to water as a working fluid. Tests are made on a thermosyphon. The experiment was performed in order to measure the temperature distribution and compare the heat transfer rate of the thermosyphon with the nanoÀuid and with pure water. The tested concentration level of the nano-particles is 0%, to 1.2%. Results show that the addition of 1.2% (by volume) of Al2O3 nano-particles in water presented improved thermal performance compared with the operation with pure water. Results showed that the total thermal resistance, using Al2O3-water based the nanofluid is enhanced by 57% at f equal 1.2 % compared to that of pure water, depending on filling ratio and volume fraction of the nano-particles in the base fluid. The experimental data are compared with the available literature and discrepancies between results are discussed.
