Thermal design and thermal analysis for the moon-landed telescope

In order to explore the plasma sphere of the earth on the moon,a moon-landed telescope(MLT) is carried out.The thermal design and the thermal analysis of a moon-landed telescope(MLT) are presented.The thermal environment of the MLT is analyzed.The thermal design of the MLT is developed.A passive thermal control system is used to control the temperature of the MLT to reduce the influence of the MLT to the external environment.The heat dissipation of detector is researched with the approach of conduction.The finite element model is built based upon the environment,the structure and thermal control system of the telescope with I-DEAS/TMG.The thermal control system is simulated and calculated.The results of analysis indicate that the temperature of optical system is-50℃~60℃ and the other parts is-110℃~105℃.The results of the simulation indicate that the thermal design is reasonable.The research method could give some guidance and reference for the thermal design of other moon-landed detectors out of the cabin.
