摘　　要：对一款分置式制冷机冷指结构进行了优化,通过优化排出器网片的填充方法,采用两种不同目数的网片组合填充方法,提高制冷机的制冷量;优化排出器的冷端堵头结构,降低了气体的流动阻力;优化排出器弹簧安装方法,减小了排出器与冷指气缸的同轴度,提高了制冷机的性能。The cold finger of a linear split miniature Stifling cryoeooler was optimized. The cooling capacity was improved by optimizing the regenerator mesh screen filling method and using two different meshes screens. The gas flow resistance was reduced by optimizing the cold end plug structure. The spring structure was optimized for reducing the concentricity with the cold finger.
