Temperature-sensitive magnetic fluids are a kind of magnetic nanofluids, in which magnetic nanoparticles with the low Curie temperature are stably dispersed in a proper carrier liquid. Owing to the low Curie temperature, the magnetization of the magnetic fluid strongly depends on its temperature. This temperature-dependent magnetization realizes a magnetically-driven heat transport device, which does not need a mechanical pump, with energy conversion from thermal to kinetic energy. In the present study, a magnetically-driven heat transport device using the temperature-sensitive magnetic fluid was fabricated and its properties relating the long distance heat transfer was investigated. As the obtained results, the temperature-sensitive magnetic fluid could be driven by applying heat and a magnetic field. Under the conditions of the magnetic field intensity of 136 kA/m and the heat flux of 5 kW/m2, the fluid was found to show the mobility and transfer the heat with a long distance of 6,000 mm.
