And, theoretical and experimental studies have been carried out of the performance of the heat transfer enhancement by adding a proper amount of nanoparticles to the thermosiphon with water as the working fluid. Compared with the ordinary thermosiphon, results indicate that this heat pipes posses such advantages as good startup, lower tube wall temperature, and its heat transfer coefficient is increased by 47～96%, heat flux is increased by 7.6～15% in the range of the experiment. The performance of the heat transfer relates to the diameter and the volume fraction of nanoparticle.

Although the TSOT heat exchanger has been successfully applied in the realm of heat-recovery in industrial boilers and furnaces, the mechanisms of TSOT and its effects of some elements on its heat transfer features are unknown. Reports about the TSOT research have seldom seen. So it is not only urgent but also important to do some investigations on TOST to enrich the heat pipe theory and guide engineering design.
