摘要 脉管制冷机中的直流流动不仅削弱了制冷机热力学性能,而且还是引起制冷温度不稳定的重要原因。如何有效抑制直流流动已成为进一步提高脉管制冷机性能并进而实现大规模实用化亟待解决的关键问题,是目前脉管制冷机的研究热点。本文首先定性分析直流对脉管制冷机性能的影响,介绍了脉管制冷机中存在的主要直流类型及其形成机理,在此基础上对其抑制方法进行了探讨。 The DC flow in pulse tube cooler not only deteriorates the cooling capacity greatly, but also the key factor causes temperature instability. Whether the cooler could be widely used heavily depends on the simpler and more effective DC flow suppression ways to be developed, In this paper, the influence of the DC flow on performance of the pulse tube cooler is qualitatively analyzed firstly, and then two primary types of DC flow and their creation mechanisms are introduced. On this basis, DC flow suppression ways are discussed.
