Waste heat recovery technology and comprehensive utilization of heat energy in various fields, the gravity heat pipe has reflected the unique superiority, according to the structure characteristics of the pipe line of gravity heat pipe, a mathematic model of the structure of the condenser. On the basis of mathematical model, through the preparation of the program C + + language, the numerical simulation study the communicating pipe type of gravity heat pipe heat transfer performance. A mathematical model is established according to the structural characteristics of the gravity heat pipe of the connected pipe row. Use FLUENT software for internal structure, to simulate the velocity vector according to the results of simulation analysis of pipeline of gravity heat pipe heat within the rationality of the steam and condensate return movement trend.engravity heat pipepipe line of typeC++numerical simulationFLUENTArticle697.334:536.2
