CTOnews.com August 11, China Electronic Technology Group Co., Ltd. announced today that recently, China Electric Science and Technology 16 Institute has broken through the key technologies of large cooling capacity, high efficiency and light Stirling pulse tube refrigerator to greatly reduce the volume, weight and power consumption of infrared detectors to meet the urgent needs of ultra-high resolution, large area array and long-line infrared cameras for large cooling capacity, long life and low vibration.

"the infrared camera carried by the satellite looks down at the ground temperature." Chinese electrical technical experts said that as long as any object above absolute zero will produce infrared radiation, if the temperature of the satellite itself is higher, it will bring a lot of interference signals, just like watching a movie to close the curtains to block out the interference light outside. In order to keep infrared cameras in a low-temperature environment, we need technical means such as refrigerators to play the same cooling role as "refrigerators."

China Electric said that in the follow-up, the technical team will focus on the pedigree and engineering of piston pulse tube refrigerators with gas bearings at room temperature, actively promote the aerospace application of pulse tube refrigerators, and make new and greater contributions to the construction of a space power.

CTOnews.com Note: 16 China Electric Power Institute, also known as "Hefei Cryogenic Electronics Research Institute", is a national first-class military research institute. Under the advocacy of Qian Xuesen and other older generation scientists, China Electric Science 16 Institute was founded in 1966 in Lueyang, Shaanxi Province, and moved to Hefei in 1985. It now has more than 700 employees, mainly engaged in refrigeration and thermal management, superconducting and cryogenic electronics technology research and development and product manufacturing. It is the only research institute specializing in the engineering application of cryogenic electronic technology in China.
