Description

technical field [0001] The invention relates to a thermal control system and a control method for complementary solar energy and temperature difference energy used in long-duration solar-powered aircraft. Background technique [0002] Solar aircraft is an unmanned aerial vehicle that uses solar energy as the main energy supply system and can fly continuously at ultra-high altitudes for more than several weeks. Because it can complete most of the satellite's work, such as reconnaissance, early warning, atmospheric observation, relay, etc., it is called "atmospheric satellite", and it is currently attracting the attention of aerospace powers such as the United States, the European Union, and Russia. However, in order to meet the requirements of long endurance, solar-powered aircraft often install a large number of solar panels during the test flight, resulting in excessive scale and uneven structural force during the descent process, resulting in disintegration in the air. The...

However, the highest photoelectric conversion efficiency of solar cells is only 24.7%, and the remaining energy is all converted into heat. If not fully utilized, the heat energy is not only a waste of limited energy, but at the same time, due to the increase in the surface temperature of the battery, the output power of the battery will reduce
