摘要

回热器是回热式低温制冷机中的关键部件

对制冷机性能有重要影响。文章阐述了回热式低温制冷机用回热器结构在近几年的研究进展

根据填料填充方式的不同

将回热器分为层叠金属丝网式、平行金属丝式、堆叠金属珠式、平行金属片式、随机丝式、金属丝网和金属珠混合填充式等六类

并总结对比了不同填充方式回热器的优缺点

提出采用回热器回热效率η、比表面积a、流动不均匀性指数Fm、流动阻力系数f、填料几何因数Γ、填料轴向导热指数Ck、长径比L/D等七个评价指标对回热器性能进行较为全面的评价

展望了回热器结构研究发展急需解决的难题及所面临的挑战。

Abstract

Regenerator is a key part of regenerative cryocoolers

and it gives predominant contribution to the performance of cryocoolers.In this paper

the recent development of regenerator in regenerative cryocoolers is described.Stacked mesh screens

parallel wires

sphere beds

parallel plates

random wire

mesh screens & packed spheres mixed packing are the commonly used configurations for regenerators

and the characters of different regenerators are discussed separately.It is suggested that the regenerator should be as...
