英文摘要：

Heat pipes have been used widely in many engineering fields due to their higher rate of heat transfer.However,the design of heat pipes often involves selection of multiple parameters and the conventional design algorithms are not efficient in optimizing these parameters simultaneously.In this paper,the thermal network model and heat transfer limit model of a typical heat pipe were built.Based on them,the optimal problem of the heat pipe is defined mathematically.Then a multi-object optimization algorithm based on the genetic algorithm is introduced to solve this problem.The results of several case studies based on this algorithm are discussed.Its effectiveness and superiority are clearly demonstrated.Since the models are built on the basic heat pipe analysis theory,the algorithm can be easily extended to solve the optimal problem of many types of heat pipe.
