Abstract
Steady-state experiments are carried out to predict the thermal performance of a loop heat pipe using the Copper–Water Nano-fluid with 1% concentration. Deionised water is considered as the baseline case for the comparison. The studies are performed for varied heat loads of 30–270 W. The cooling water is supplied at 20 °C with a flow rate of 40 L/h. A parametric study is carried out for the thermal resistance, evaporator temperature and interface temperature of the heat pipe that affects its performance. The results highlight a notable enhancement in the thermal characteristics of the heat pipe using the Nano-fluids in comparison to the baseline case. The evaporator temperature and the thermal resistance of the heat pipe are reduced by 30% and 17%, respectively using the Nano-fluids. An extremum model is used to predict the minimum evaporator temperature of the heat pipe at the optimal power (heat) input.
