Description
Technical Field
The invention relates to the technical field of aerospace application, in particular to an on-orbit temperature control system and method for a spacecraft satellite-borne single machine.
Background
The satellite thermal control technology aims to control the heat exchange process of the internal environment and the external environment of a satellite and achieve the purpose that the thermal balance temperature of equipment on the satellite is in a required range. The thermal control technology is an important component of the aerospace technology, and the design level and quality of the thermal control technology affect the working state, service life and reliability of the whole satellite. With the continuous development of the aerospace technology, the application range of the satellite is gradually expanded, and the effective load on the satellite varies greatly due to different functions, so that the satellite thermal control technology continuously faces new challenges.
In the process of designing the satellite-borne single machine of the spacecraft, temperature design needs to be carried out on different modules in the single machine, and due to the limitation of functional requirements, heat consumption and temperature requirements of all the modules in the spacecraft, the thermal control requirements of the different functional modules need to be comprehensively considered in the design process.
In the aspect of the on-rail temperature control technology of the spacecraft satellite-borne single machine, the method is generally adopted to control the temperature of the mounting surface of the satellite-borne single machine. With the continuous development and progress of the aerospace technology, the functions of a single machine for assembling spacecrafts such as satellites and the like are diversified day by day, and because different components in the single machine have different temperature requirements, the single machine is generally designed by adopting the maximum envelope of the working, starting and storing temperature ranges of the components in the design process of the single machine. The general electronics device can bear comparatively abominable temperature range, if carry some components and parts that have special temperature control demand in the unit, comparatively special temperature control demand such as lower operating temperature upper limit, start and storage temperature lower limit, temperature stability, temperature homogeneity and temperature rising and falling speed. According to the existing single-machine thermal control design concept, the temperature control strategy of the whole single machine is strict, and unnecessary resource waste is caused to temperature control.
The conventional satellite-borne single-machine thermal control design mode is that structural layout among modules in a single machine is carried out according to different module temperature requirements carried by the single machine, the module with high heat consumption needs to be installed near a single machine installation surface, an optimal heat dissipation path is provided for the module, the module with special temperature requirements generally adopts good thermal contact with a heat exchange surface, and the temperature of the modules in the single machine is controlled by controlling the boundary temperature of the heat exchange surface. The main defects of the design mode are that the temperature control of a single machine interface is limited by a temperature sensitive device, and all single machines are required to be controlled in a more severe temperature range. Most of the conventional satellite-borne single machines are electronic components, and the components can bear higher working temperature and lower storage temperature. According to the law of thermodynamics and the thermal control design principle of the spacecraft, the stricter the boundary temperature control requirement is, the more thermal control resources are needed, including heat dissipation channel resources, power resources and the like. This results in an increase in the overall demand due to the local demand, resulting in unnecessary waste of resources.

designing the area of the radiator according to the heat consumption of the second single-machine module and a temperature control target, and adhering cerium glass silver-plated secondary surface mirrors or heat control white paint on the two sides of the radiator to increase the heat dissipation efficiency of the radiator;
the temperature measuring device and the heating assembly control the temperature of the heat transfer device through closed-loop control so as to control the temperature of the second single machine module.
10. An on-orbit temperature control method for a spacecraft satellite-borne single machine is characterized by comprising the following steps:
heat is conducted between the first single-machine module and the spacecraft mounting plate;
the second stand-alone module is more sensitive to temperature than the first stand-alone module;
arranging a heat insulation device between the first stand-alone module and the second stand-alone module to conduct or insulate heat between the first stand-alone module and the second stand-alone module and to control the temperature of the second stand-alone module independently; wherein:
and the heat conductivity coefficient of the material of the heat insulation device is set according to the heat exchange quantity requirement between the first single machine module and the second single machine module.
