An experiment was performed to find out the effect of thermal efficiency of the heat pipe using Al2O3-BN/WATER hybrid nanofluid as a working fluid. We have taken the average size ofparticle Al2O3-BN as 40 nm and the concentration of Al2O3-BN nano particle in the fluid is 100 mg/lit. This research discusses about the different effect of heat pipe parameter like inclination angle effect, cooling water flow rate at condenser of heat pipe and heat given as input on the thermal efficiency and resistance. The aim of this paper is to experimentally find the behavior of nanofluid to improve the performance of a circular type of heat pipe. Pure water and Al2O3-BN water based nanofluid are used as working fluids in heat pipe. Thermal resistance decreases with increasing Al2O3-BN water based Nano fluid heat pipe compared to that of pure water based heat pipe.

Keywords: heat pipe, nanofluids, thermal efficiency, heat input, heat pipe inclination
