Abstract: The lunar sampling cameras are installed on the robot arm of the lunar robotic sampling and return mission explorer. The cameras have a very small quality, but a very large heat rate. Both of the cameras required long-term work in high-temperature environment, thus the temperature level becomes an important factor to ensure normal work of the cameras. According to the working mode of the camera and the motion attitude of the manipulator, a thermal analysis model for adaptive motion is constructed, and several schemes to realize the high-temperature heat dissipation of the camera are presented. Through the comparative analysis, based on the OSR coating and white paint, the thermal control design of the cameras is determined, and the critical heat dissipation model of the cooling coating is selected. The research could provide reference for the thermal design of above deck equipment.
