| Abstract: | A new lumped-parameter model is developed to predict the transient performance of the two phase closed thermosyphon through analysis of the heat transfer mechanism inside it. This model introduces three lumped-parameter units the evaporator, the insulator and working fluid, the condenser. With the reported heat transfer correlations, energy equations for the units are established respectively. Calculations on the temperature distribution and the dynamic characteristics of the thermosyphon are performed under the conditions of different heat loads, cooling rates and working fluids. Compared with the work done before, such a model offers a comprehensive but relatively simple method. |
