Steady Sate Modeling of LHP and Analysis

摘要：

　　An ammonia-stainless steel steady state modeling of loop heat pipe was established,the impacts on the LHP operating temperature induced by alterable heat loads under 3 operating cases (the different position between evaporator and condenser,the changing of ambient temperature and the changing of heat sink temperature) were analyzed and conclusions were made.Changing the position between evaporator and condenser has a significant influence on the LHP operating temperature.Anti-gravity operation will reduce the performance of the LHP,this phenomenon is obviously in low heat load range.Further more,increasing of fluid pressure drop in the loop will induce decreasing of the LHP performance.The temperature difference between ambient and heat sink will influence the transition heat load (from variable conductance mode to fixed conductance mode),the bigger the temperature difference the higher the transition heat load.
