本文对235台制冷机的数据进行了测量，制冷功率在几十瓦以下，工作温度在4 ~ 120 K。讨论了冷却性能、质量和尺寸、成本、寿命和可靠性方面的最新技术水平和发展趋势。这些数据与以前的调查进行了比较，以探索历史趋势。冷却性能的改进主要是在80 K低温冷却器，效率增加了约5倍。冷却器的尺寸没有显著减小。主要减少是在80 K冷却器，因为更高的效率。在调查中，成本与输入功率、冷却功率和工作温度有关。成本发展被认为是与学习曲线相关的。自90年代中期以来，斯特林型低温制冷机的寿命增加了一个数量级，从通常的0.5年增加到5年或更长。讨论了“可靠性”一词的混淆问题。(C)2003爱思唯尔科技有限公司版权所有。
A cryocooler survey has been performed on data of 235 cryocoolers, with cooling powers below some tens of watts and operating between 4 and 120 K. The state-of-the-art is discussed and trends are investigated on cooling performance, mass and size, cost, lifetime and reliability. The data were compared with earlier surveys to explore historical trends. Improvements in cooling performance were mainly in 80 K cryocoolers, an increase in efficiency by about a factor of 5. Coolers did not reduce in size significantly. Main reduction was in 80 K coolers because of the higher efficiency. In the survey, cost is related to input power, cooling power and operating temperature. Cost development is considered and related to learning curves. Since the mid-90s, the lifetime of Stirling-type cryocoolers has increased by one order of magnitude from typically 0.5 to 5 years or more. The confusion that exists on the term "reliability" is discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.
