摘要

The waste heat from the space solar-power system, which supplies 5 MW of electricity to a power transmission line on Earth, is estimated, and the liquid droplet radiator for handling the waste heat are examined on the basis of experimental results obtained under microgravity for droplet generation and droplet collection of the liquid droplet radiator. The following results have been obtained. First, an active heat removal system for the power generation unit in the photovoltaic power system is not necessary when the concentration ratio of solar energy is smaller than 1.34, whereas for the liquid droplet radiator, with silicon oil as working fluid, in the solar dynamic power system, the droplet sheet for radiating the waste heat must be 147 m long, 65.1 m wide, and 0.998 m thick. Second, the droplet sheet of the liquid droplet radiator, in which the working fluid is silicon oil, must be 107 m long, 43.2 m wide, and 0.998 m thick to manage the waste heat from the power distribution unit and the power transmission unit in the photovoltaic power system, whereas it must be 107 m long, 65.2 m wide, and 0.998 m thick in the solar dynamic power system.
