【Abstract】 Heat transfer limits of the separate type heat pipe were analyzed using the heat pipe theory and the natural circulation of the hydrodynamical theory. It was pointed out that the heat transfer limits of the separate type heat pipe were concerned with the heat flux in the heat transfer process and the liquid filling ratio in the heat pipe. Under the high heat flux condition, the separate type heat pipe had heat transfer limits as follows: (1) dry-out heat transfer limit in the evaporator; (2) boiling heat transfer limit in the evaporator; (3) condensation heat transfer limit in the condenser; (4) flowing heat transfer limit in the circular loop. The difference of heat transfer limits between the separate type heat pipe and the thermosyphon was that in the separate type heat pipe,there was no flooding heat transfer limit at all. The analyzing results have some significance to the applying to the separate type heat pipe. 更多还原
