Thermal performance of two phase closed thermosyphon using nanofluid
A two-phase closed thermosyphon (TPCT) is an enclosed, passive device for heat transmission. It consists of an evacuated close tube filled with a certain amount of working fluid. Fluids with suspended nanoparticles (particles smaller than 100 nm) are called nanofluids that they have a great potential in heat transfer enhancement. In this paper, the thermal performance of a two-phase closed thermosyphon filled with Al2O3nanoparticlesusing water as the base fluid. The experiment was performed in order to measure the temperature distribution and compare the heat transfer rate of the thermosyphon heat pipe with nanofluid and with distilledwater. Nanofluids were prepared in 1% volumetric concentrations. Different filling ratios and heat loads (100 W, 200 W, 300 W, 400 W, 500 W and 600 W) were applied to the evaporator section. Results show that the addition of 1% (by volume) Al2O3of nanoparticles in water presented improved thermal performance compared with the operation with distilled water.
