Thermal Design and Thermal Analysis of Space Observation Equipment

Abstract

On the research of observation equipment,the method of heat conduction was chosen aiming at high-power electronic components based on the working environment and structure characteristics.The thermal design was finished on the research of heat conduction theory for the high-power electronic components.After the finite element model was built,the relations between the thickness and contact area of heat sink and the steady temperature of high-power electronic components were analyzed,and the design of heat sink was optimized.The experimental results showed that the equipment worked well in range of-30~50 ℃ environment,and the steady temperature was less than 85 ℃.Therefore,the equipment of thermal design can satisfy the temperature requirements in the space environment.
