Problems solved by technology

However, the effect of using heating to decontaminate is very limited. Not only will the work of the detector be delayed, but the gas molecules evaporated by heating will be deposited on the focal plane again within a certain period of time, causing molecular pollution again and affecting its work. quality

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like figure 1 As shown, a low-temperature refrigeration system with an adsorption device for cooling a space probe includes: a compressor 1, a transmission pipe 2, a gas storehouse 3, an inertial pipe 4, a hot end heat exchanger 5, a regenerator 6, Pulse tube 7, cold end heat exchanger 8 and adsorption device 9. The adsorption device 9 is installed radially around the cold end heat exchanger 8 to adsorb gas molecules in a vacuum environment. The low-temperature refrigerator of this embodiment adopts a coaxial pulse tube refrigerator, but its structure can also be linear or U-shaped, and the refrigerator can be a Stirling refrigerator or a J-T refrigerator, and is not limited to a single-stage refrigerator. , can be a multi-stage refrigerator.

[0026] like figure 2 As shown, it is a low-temperature refrigeration system equipped wit...

Abstract

The invention discloses a low temperature refrigeration system provided with an adsorption device and used for cooling a space probe. The low temperature refrigeration system comprises a compressor, atransmission tube, an air reservoir, an inertial tube, a hot end heat exchanger, a regenerator, a vessel, a cold end heat exchanger and the adsorption device. The adsorption device is installed around the cold end heat exchanger in the radial direction, the cold trap effect of the cold end heat exchanger is used for adsorbing gas molecules in the vacuum environment, and the adsorption device plays a role in maintaining the cleanliness of the working environment of the space probe while providing the low-temperature environment required by the space probe. Compared with a traditional heating decontamination mode, the low temperature refrigeration system is higher in decontamination capability, more thorough in decontamination, energy-saving and simple in equipment structure, and is suitable for space refrigeration systems with different low-temperature refrigerators, can well meet the requirements of the space probe for environmental temperature and environmental cleanliness, and guarantees long-term stable operation under the condition of high performance.

Description

technical field [0001] The invention belongs to the field of low-temperature refrigeration in space, and in particular relates to a low-temperature refrigeration system with an adsorption device for cooling a space detector. Background technique [0002] For spacecraft such as observation satellites, astronomical satellites, monitoring and tracking satellites, the detectors and related optical instruments installed on them are necessary components to complete their work. In order to reduce the thermal noise of these instruments and improve the imaging quality, it must be equipped with a low-temperature refrigeration system to provide an ambient temperature suitable for its work. [0003] In addition, the performance of the detector is also affected by the cleanliness of its environment. During the working process of spacecraft, some materials used in it will release gas molecules under vacuum conditions, mainly water vapor and carbon dioxide molecules. The detector is usua...
