摘要
介绍了斯特林型脉冲管制冷机在理论分析和实用化方面的进展。与斯特林制冷机相比 ,由于低温端没有运动部件 ,脉冲管制冷机在寿命、可靠性和振动等方面有明显的优势 ,同时直流现象的发现和对它的抑制 ,以及双向进气、长颈管等调相机构的应用 ,使得斯特林型脉冲管制冷机的效率也可以达到或超过斯特林制冷机 ,从而使斯特林型脉冲管制冷机在空间。
The recent advances in Stirling type pulse tube cryocooler are reviewed.Compared with Stirling cryocoolers,pulse tube cryocoolers has advantages of life,reliability and vibration because of no moving parts in the cold head.With the understanding of the D C flow and the applying of the double-inlet and inertance tube,the efficiency of the pulse tube cryocooler is matching or exceeding that of Stirling cryocoolers.Stirling type pulse tube cryocooler will have a great use in cooling infrared sensors and superconductors for space and military applications.
