ファンの電圧制御による脈動流の生成と伝熱促進の可能性

抄録

This study describes a possibility of an improvement of fans' cooling technique while decreasing time-averaged power consumption of a fan mounted in electronic equipment. The cooling performance of the square prism object by the axial small fan was evaluated while changing the input voltage to the fan periodically. Through the experiment, it is found that the fan's cooling performance can be maintained while decreasing the time-averaged power consumption according to the pattern of the intermittent operation of the fan. The possibility of the energy saving of the fan cooling can be confirmed.
