Abstract: |
In order to investigate the design optimization of the loop heat pipe (LHP), the influence to the heat transfer performance of cylindrical LHP was analyzed when the length of evaporator changed. The optimization of size design and simulation analysis of the LHP evaporator were studied. The mathematical model between the length, the pressure and the temperature distribution of the LHP evaporator was developed. The thermal/fluid simulation model was established by SINAPS software, which could simulate the temperature and pressure change of the LHP in different lengths of the evaporator. The simulation results show that the thermal/fluid model could rapidly evaluate the impact of the size change of the evaporator on the temperature and pressure of all components of LHP, which offered the method for the evaporator optimization in size design. The thermal/fluid model could also be used for the optimization of the whole LHP system to guide the design and engineering application for further research of the LHP. |
