AI Technical Summary
Existing satellite thermal control systems cannot achieve infrared stealth without compromising visible light stealth, and the uneven temperature distribution on the satellite surface makes it easy to be detected by infrared detectors.
Combining a thermochromic intelligent thermal control coating and a variable-direction active heat pump circuit, the coating adjusts its infrared emissivity according to temperature changes, while the active heat pump circuit transfers heat inside the satellite to regulate the temperature and reduce temperature differences.
It achieves adaptive control of satellite surface temperature, reduces temperature difference, improves temperature uniformity, enhances infrared stealth effect, and ensures satellite safety and concealment.
