Performance Analysis of a Two -Turn Oscillating Heat Pipe under Various Filling Ratios and Power Intensities

In this study, the performance of a two-turn oscillating heat pipe was examined under different filling ratios and power intensities. The heat pipe had an inner diameter of 2 mm and an outer diameter of 4 mm, consisting of three sections: evaporator, adiabatic, and condenser. To evaluate the effect of filling ratio and power on heat transfer, filling ratios of 0%, 30%, and 50% were tested at power levels of 5 and 10 watts. The results showed that increasing the filling ratio led to lower temperatures in the evaporator, adiabatic, and condenser sections, and thermal stability was achieved more quickly. Additionally, increasing the power input caused a rise in the evaporator temperature, but the condenser temperature significantly decreased with higher filling ratios. These findings indicate that optimizing the filling ratio can enhance the performance of heat pipes.
