摘要
脉管制冷机的微振动、高可靠、轻量化等特点,已经在航天红外探测器冷却方面取得广泛应用.作为新发展的调相方式,活塞调相技术在实现更高能效、更低温度、更低振动输出等方面具有独特优势.基于活塞调相的基本特性,针对主动活塞调相、气动功回收活塞调相和主动功回收活塞调相三种主要的活塞调相方式进行气动力分析.分别将不同活塞调相方式应用于10～80 K脉管制冷机研制,验证活塞调相对多种形式下脉管制冷机能效提升应用效果.从应用视角出发,探讨活塞调相后续研究及改进方向.
Abstract
The micro-vibration,high reliability and light weight of pulse tube refrigerators have been widely used in aerospace infrared detector cooling.As a recently developed phase shift method,piston shift technology has unique advantages in achieving higher energy conversion efficiency,lower temperature,and lower vibration.Based on the essential characteristics of the piston-type phase shifter,aerodynamic analysis is conducted for three main methods:active piston phase shifter,pneumatic piston shifter with acoustics power recovery,and active piston phase shifter with acous-tics power recovery.Different piston phase shifter methods are applied to develop 10～80 K pulse tube refrigerators,and the effects of the energy conversion efficiency improvement of pulse tube refrigerators in various forms are verified.From the perspective of the application,the subsequent research and improvement direction of the piston-type phase shifter is discussed.
