Aerospace loop heat pipe radiator composite thermal control system

Abstract

The invention provides an aerospace loop heat pipe radiator composite thermal control system. The system comprises an evaporation end of a flat plate type loop heat pipe, a ceramic heating sheet, a radiant panel, a solar cell panel, a storage battery, a circuit, an evaporation loop pipeline, an electromagnetic valve and a temperature sensor, and the ceramic heating sheet is attached to the upper part of a heat dissipation component; the evaporation end of the flat plate type loop heat pipe is tightly attached to the ceramic heating piece, the condensation end dissipates heat outwards through a structure which extends and is embedded into the radiant panel by means of a condensation pipeline, and condensed liquid obtained after heat dissipation circulates back to the evaporation end; the electromagnetic valve is mounted on the evaporation loop pipeline; one end of the storage battery is communicated with the evaporation end of the loop heat pipe through a line, and the other end is connected with the solar panel through a line; and the temperature sensor is installed on the outer side of the heat dissipation component. The heat pipe radiator heat dissipation system and a solar electric heating system are creatively combined, and the zero-energy-consumption heat dissipation and heat preservation effects can be integrally achieved.

Description

technical field [0001] The invention belongs to the field of solar energy and loop heat pipes, in particular to a composite thermal control device for aerospace loop heat pipe radiators. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Energy issues have become one of the most prominent issues in the contemporary world. Therefore, seeking new energy sources, especially non-polluting clean energy sources has become a research hotspot. [0003] Solar energy is an inexhaustible clean energy with a huge amount of resources. The ...

Problems solved by technology

[0013] The launch volume of small and medium-sized satellites is increasing day by day. Civilian and commercial satellites account for 69% of small and medium-sized satellites. However, the relevant heat dissipation technologies are still very scarce, and most of the existing heat dissipation solutions are high in cost and short in life. It is imminent to adapt the traditional heat dissipation method to meet the needs of small and medium space satellites
