Abstract： Aiming that the current existing measuring method about heat pipe performance using manual shaking and discerning the voice，has the weak point of low efficiency and poor accuracy，a performance test system of gravity heat pipe was developed. The system，with high precision annular groove as the heat source，using contactless infrared temperature measurement technology，and with measuring method of the assembly line measure temperature，can automatically determine the heat transfer performance. By describing the working principle of heat pipe，a model of test system was established. Based on the structure of whole test system，the programmable logic controller（PLC）program was designed and developed，and the test software was developed with object-oriented method on the .Net development platform. On this basis，the stability design of anti-interference technology was applied in the system to overcome the interference of external factors，ensure the reliability of whole system. The results indicate that the test system is stable and reliable，has high measuring efficiency and accurate data.
