120 Hz线性压缩机 脉管 斯特林 匹配设计 120 Hz linear compressor pulse tube cooler Stirling cooler coupling analysis
摘要
针对一款频率为120 Hz的同轴型脉管冷指,设计了一台高频动磁式线性压缩机,并采用有限元分析方法进行了电机本体的设计。实验结果表明,制冷机在34 W输入功率下可实现80 K 时1 W的制冷性能。在此压缩机模型的基础上,与一台相同频率的斯特林冷指进行了匹配,通过对压缩机的动子板簧重新设计,在34 W输入功率下达到了80 K时 1 W的制冷量,证明此设计方法有效。
Abstract
A high frequency moving-magnet linear compressor was designed for a 120 Hz coaxial pulse tube cold finger and a motor model was designed by means of finite element analysis. The experimental results showed that the crycooler could achieve 1 W 80 K cooling capacity with input power of 34 W. On the basis of this compressor model, the compressor was used to drive a Stirling cold finger with same frequency. By redesigning the flexure-bearing and moving mass, the Stirling cold finger achieved 1 W 80 K cooling capacity with input power of 34 W. This showed that this design method was effective.
