Abstract

The invention provides a satellite-borne single-machine differential temperature control system and method, and the system comprises a first single-machine module which is configured to carry out theheat conduction with a spacecraft installation plate; a second single-machine module which is configured to conduct heat with a radiator through a closed-loop conduction module, wherein the maximum normal working temperature of the components of the second single-machine module is lower than the maximum normal working temperature of the components of the first single-machine module; and the minimum normal working temperature of the components of the second single-machine module is greater than the minimum normal working temperature of the components of the first single-machine module.

Description

technical field [0001] The invention relates to the technical field of aerospace applications, in particular to a space-borne stand-alone differential temperature control system and method. Background technique [0002] The purpose of satellite thermal control technology is to control the heat exchange process inside and outside the satellite, so that the thermal balance temperature of the equipment on the satellite is within the required range. Thermal control technology is an important part of aerospace technology, and its design level and quality affect the working status, life and reliability of the entire satellite. With the continuous development of aerospace technology, the application range of satellites is gradually expanding, and the payloads on the satellites vary greatly due to different functions. Therefore, satellite thermal control technology is constantly facing new challenges. [0003] In the thermal control design process of spacecraft space-borne stand-al...
