Abstract: Heat pipes are characterized as superconductors of heat as they are best known for excellent heat dissipation properties with minimum heat loss. Moving from conventional to advance heat pipes, a lot of research and experimentation has been done in the 21st century due to modernization and miniaturization of equipment.The present study also aims at discovering the tilt angle of the same heat pipe at which highest heat transfer coefficient of condenser section is offered. It was observed that maximum heat transfer coefficient across condenser section of heat pipe under forced convection was obtained at 25° tilt angle under air velocity of 3.36 m/s having 73.127 W/(m2K) value whereas minimum value of heat transfer coefficient was observed at 0° tilt angle under air velocity of 1.35 m/s having value as 36.367 W/(m2.K). Many different working fluids can be used inside the heat pipe. In recent times, nanoparticles are also being employed in heat pipes to improve their performance as they decrease the thermal resistance leading to high performance of heat pipe. Beyond 25° tilt the performance of heat pipe decreases due to flooding of evaporator section of heat pipe.
