Abstract

Heat pipe and Two-Phase Closed Thermosyphon (TPCT) are devices for heat transmission. It consists of an evacuated close tube filled with a certain amount of working fluid or nanofluid. Nanofluids being suspensions of nano-sized solid particles in a base fluid are considered as new mediums for heat transfer in thermal devices. The present study is an experimental investigation which examines the effects of CuO-Acetone nanofluids with different solid weight fraction on the thermal performance of a two-phase closed thermosyphon. Experimental results show that in most cases the thermal efficiency decreased except at 1 %wt concentration. Also in comparison to pure acetone. Thermal resistance of TPCT dectreased in 0.5 and 1 %wt concentrations. In addition, the impact of two filling ratios at 1 %wt oncentration was studied.
