Abstract
This invention discloses a high-efficiency energy-saving energy storage system for satellite thermal balance based on liquid metal and solar energy. The system includes a concentrating solar thermal collector, a liquid metal circulation loop, a microchannel coupling structure, an adaptive quantum thermal switch, a phase change energy storage unit, an isotope-assisted heat source, and an intelligent drive and control system. This invention directly converts solar energy into thermal energy to drive the thermal cycle, combines phase change materials to store and release surplus heat, and utilizes a quantum thermal switch to intelligently regulate the heat flow path. This achieves a significant reduction in satellite thermal control power consumption, a significant increase in energy self-sufficiency, and control of equipment temperature stability under extreme temperature difference environments.
