Abstract: The working principle and properties characterization of two closed thermosyphon were introduced in this paper. The research on the closed thermosyphon heat transfer enhancement was summarized from aspects of inherent parameters and operating conditions. The main mechanism of influence on performance of the closed thermosyphon by changing parameters was introduced,such as type of working fluid,filling ratio,structural parameters,surface treatment, heating power, operating temperature, inclination angle and,cooling medium flow rate. Research status and influence of variation of the above factors on heat transfer performance of closed thermosyphon were summarized. Shortcomings and limitations of the present study on heat transfer enhancement of closed thermosyphon were also pointed out. Suggestions were put forward for further researches,for example,the synergy between various factors should be determined,influence of other factors should be eliminated,scope of variables should be expanded in researches. In addition,it was suggested that study on enhancement of heat transfer in closed thermosyphon and strengthening mechanism of heat transfer and mass transfer in the closed space,such as boiling and condensation,should be combined. Heat and mass transfer theory and calculation formula should be improved.

Key words: closed thermosyphon, heat transfer enhancement, properties characterization, inherent parameters, operating conditions
