Temperature sensitive magnetic fluid (TSMF) has a property of magnetization dependent on temperature subjected to an applied magnetic field. In the present study, a binary magnetic fluid, which is a mixture of the TSMF and an organic secondary fluid, is utilized in a heat transport device to enhance its circulation. In order to verify the performance of the TSMF mixture in the heat transport device, the driving characteristics of this heat transport device are studied both experimentally and numerically. From the results it is found the driving force is enhanced greatly when the magnetic field intensity increases.
