<p>The self-circulating thermosyphon (SCTS) for transporting solar energy was developed. This device is driven by buoyancy of vapor generated in the heater. Thus, SCTS can operate without an external power supply, and as simple structure. The solar radiation varies time to time. Therefore, the transient behaviors against varying thermal energy are important subjects. We examined about the dynamic characteristics for fluctuations of thermal energy in this study. To examine the dynamic characteristics of SCTS, the thermal energy at the heater was changed in time. When the thermal energy increased, the fluctuations of flow velocity occurred. And, even when the thermal energy decreased, fluctuations occurred. The frequencies of these fluctuations were almost the same.</p>
