AI Technical Summary
The heat dissipation area of high-power modules in low-Earth orbit communication satellites is limited, resulting in low heat transfer efficiency and high cost. Existing passive thermal control methods cannot adjust this, leading to energy waste and long production cycles.
A temperature control system based on a fluid loop is adopted, which combines a single-phase fluid loop with a deployable radiator. The working fluid is driven by a mechanical pump to achieve efficient heat collection and long-distance transmission. The heat dissipation area is expanded by deploying the radiator, and the radiation efficiency is improved by combining a high emissivity coating.
It achieves efficient thermal management, meets the heat dissipation requirements of multi-heat source satellites in extreme environments, and features high reliability, low power consumption, and strong scalability, providing a standardized and modular thermal control solution.
