摘要：
This paper establishes a mathematical model of the internal working substance flow and heat transfer of a gravity naphthalene heat pipe based on the modified Nusselt model. This study also conducts a simulated calculation of the condensation section of a naphthalene heat pipe and fabricates a naphthalene heat pipe for a heat transfer performance experiment. The analysis of the simulation results and Nusselt's calculated values as well as a comparison between the simulation results and the experimental data show that the simulated value of the modified model agrees with the experimental value and can accurately predict the performance of the naphthalene heat pipe.
