Thales rotary cooler efficiency improvement

To cool infrared detectors, it is essential to use cryogenic rotary coolers that are reliable and have optimized Size, Weight, and Power (SWaP) characteristics. The development of efficient rotary coolers makes it possible to maintain the same cryogenic performance while reducing their physical dimensions. Moreover, operating at lower rotational speeds contributes to improving reliability, reduces noise and lifespan. This paper presents an overview of the performance characteristics of Thales cryogenic rotary coolers, highlighting their capabilities in achieving cryogenics temperature regulation. We detail key performance metrics such as cooling power, reliability, quietness, and operational lifetime. Additionally, recent development efforts aimed at enhancing cooler efficiency are discussed, including innovations in thermodynamic cycle optimization and materials engineering. These improvements contribute to reduced power consumption, increased cooling capacity, and extended service intervals, reinforcing Thales’ position as a leader in cryogenic cooling solutions for demanding defense, surveillance and industrial environments.
