Abstract
Heat transporting characteristics are investigated experimentally for a heat transport device using a temperature-sensitive magnetic fluid. In the present study, in particular the regenerative thermomagnetic heat cycle is considered by allowing heat conduction in the inner pipe wall of the device. According to the heat transport configuration studied, the lower end of the device is heated while the upper end is cooled isothermally when the device is placed vertically. Experimental results show that a relatively high amount of heat can be transported in comparison with the case of an adiabatic inner pipe wall, indicating that the thermomagnetic heat cycle in the device is improved. The correlation obtained from one-dimensional analysis provides a reasonable means of assessing estimating experimental data when the thermomagnetic heat cycle based on the working principle is satisfied.
