The change in heat transport characteristics was investigated experimentally for a closed-type thermosyphon with a circular tube shape using water as the working fluid when air is mixed inside. As a result, it was found that the temperature of the single tube thermosyphon decreased due to the air stagnation in the upper part of the thermosyphon. On the other hand, in the case of a double circular tube structure with a circular tube inserted inside the thermosyphon, the heat transfer rate increased compared to that of a single tube due to the circulation flow containing air inside the thermosyphon under specific experimental conditions.
