Driving Characteristics of a Mini Magnetically-driven Heat Transport Device using Magnetic Fluids

摘要

Temperature sensitive magnetic fluids (TSMFs) have a temperature-dependent magnetization, which thermal flow behaviors are able to be actively controlled by using heat and an external magnetic field. In this paper, we proposed a mini magnetically-driven heat transport device using a binary TSMF, which is a mixture of the TSMFs and a low-boiling-point organic solution. This device can transfer the heat without mechanical pumps. In the present work, the feasibility and driving characteristics of the mini magnetically-driven heat transport device using a binary TSMF are investigated and the results show that the binary TSMF can be circulated with the maximum velocity of 10.2 mm/s under the magnetic force generated by the temperature difference between the heat source and cooling component in the device.
