Abstract This paper investigates the thermal environment about Lunar surface. Based on the requirements of landing mission near the equator of the moon, the heat rejection scheme of the Manned Lunar Lander Module was designed under the high temperature environment during the moon day. The Lunar Lander thermal control system(TCS) accomplished the heat acquisition function using various coldplates and heat exchangers, and the heat transport function was accomplished using a double-loop system architecture. For the majority of the mission, heat rejection was accomplished using deployable radiator. A sublimator was chosen as the supplemental heat-rejection device. The instantaneous radiator heat rejection capability and heat rejection requirement by the sublimator during moon day was analyzed. The simulation program of TCS was established based on Python language, and the performance of the TCS during lunar day was simulated. The results show that when the radiator area is 29m2, the thermal control system can meet the temperature control requirements of the equipment inside and outside the cabin. Sublimator as a heat-rejection device can reduce the radiator area.
