摘要：
High-temperature heat pipe is the key technology for efficient heat transfer in high-temperature fields. To develop high efficiency heat pipes further and improve the heat transfer performance in industrial process, gravity heat pipes with molten salt as heat transfer medium was developed. A high-temperature heat pipe test bench was set up and effect of working fluids and inclination angles on the startup characteristics and isothermal performance of the gravity heat pipe was studied experimentally. The results showed that as the inclination angle was 45° and 60°, the startup characteristics of heat pipes with AlBr3 and TiCl4 as working fluids was the best respectively, while the isothermal performance of the heat pipes was the best as the inclination angle was 60°. The inorganic salts AlBr3 and TiCl4 are used as the heat transfer working medium, and the gravity heat pipe has good starting and isothermal properties. © 2020, Chemical Industry Press Co., Ltd.
