This platform supplies multiple functions for the observation station, such as dependent power source, indoor environment, automatic data acquisition and wireless transmission. It successfully overcomes severe environment like extremely cold, low pressure, oxygen-poor, and provided automatic astronomical observation and other scientific research for our country in astronomic region. However, weakness exists in the first generation system like structural design, heat transfer optimization. Therefore, thermal analysis of the capsule of the supporting platform was carried out in this article, a software called Flotherm was employed to dynamically simulate the internal temperature distribution of the capsule, obtaining temperature distribution data and comparing them with the real data to make clear that this simulation has high reliability. This article supplies theoretical support for developing more reasonable energy controller support system. Keywords: Thermal analysis; Dome A; A
