The invention discloses a thermal management system for a solar aircraft, the solar aircraft and a thermal management method. The thermal management system comprises solar cells and a radiation cooling thin film arranged on the solar cells, wherein the solar cells are laid on the upper surface of the solar aircraft to absorb ultraviolet light and visible light and convert the light into electric energy, the radiation cooling thin film allowing the ultraviolet light and visible light to transmit comprises a surface layer and at least one bottom layer, the surface layer is formed by polymerization of a semiconductor material or doping a high transmittance material with nanoparticles, and the bottom layer is arranged between the solar cells and the surface layer, and the bottom layer comprises a high transmittance material. The thermal management method comprises the steps that: sunlight is absorbed by means of the solar cells via the radiation cooling thin film, part of the ultraviolet light and visible light is converted into electric energy, another part of energy is converted into thermal energy, the radiation cooling thin film radiates part of thermal energy for reducing the solar energy surface temperature, and the remaining thermal energy which is not radiated by means of the radiation cooling thin film can be stored in a phase-change material inside square cavities of thewings through heat conduction.
Description
technical field [0001] The invention relates to the field of thermal management of solar-powered aircraft, in particular to a thermal management system for solar-powered aircraft, a solar-powered aircraft and a thermal management method. Background technique [0002] Because of military aspects such as border patrol, reconnaissance, communication relay, electronic countermeasures, atmospheric research, weather forecast, environmental and disaster monitoring, crop telemetry, traffic control, telecommunications and television services, natural reserve monitoring, alien planet detection, etc. In terms of unique advantages, developed countries such as the United States, Switzerland, and Russia carried out research on solar-powered aircraft and related technologies at the end of the last century. [0003] However, due to the particularity of the flight environment and the form of energy utilization, the solar-powered aircraft disintegrated due to thermal stress and large deformat...
