A new designed heat pipe: an experimental study of the thermal performance in the presence of low-frequency vibrations

摘要

New experimental results present the effects of low-frequency vibrations in a horizontal heat pipe. The temperature difference between the evaporator and condenser of the heat pipe was measured under different heat transfer rates, filling ratios and frequencies. The low-frequency vibrations imposed a significant effect on the thermal performance as the best performance was achieved with the thermal resistance 0.05 K/W in the frequency 25 Hz.
