感温性磁性流体を用いた磁気熱輸送に関する研究

抄録

In the present study, a miniaturized magnetically-driven heat transport device using a binary temperature-sensitive magnetic fluid is newly designed, and its driving characteristics are investigated to develop it for the application for CPU cooling. The experimental results show that the measured flow rate periodically oscillate with the time elapsing. The reason is revealed from the numerical results that a gas bubble moves from high to low pressure region due to the effect of the magnetic buoyancy. Consequently, it is found that the bubbles trapped in the low pressure region lead the periodically oscillating flow rate.
