Abstract

A binary temperature-sensitive magnetic fluid (binary TSMF) is a mixture of a temperature-sensitive magnetic fluid and low-boiling point organic solution. An external magnetic field and heat are able to actively control the thermal flow behavior of the binary TSMF. In the present work, we make a miniaturized magnetically-driven heat transport device using the binary TSMF with the diameter of the tube of 1.54 mm, and investigated the flow characteristics at different magnetic field intensities andheating conditions. The results show that maximum flow rate is 1646 μl/min (maximum velocity 14.7 mm/s). The flow rate depends on the external magnetic field intensity, heat flux and the heating position with respect to the magnetic field distribution.
