谁知道冷凝泵？

那位哥哥能介绍一下冷凝泵的工作原理

谢谢！

The principle function of a cryopump system is to capture and retain gases from within a vacuum chamber. Cryopumps are ultra-clean, contaminant-free dry pumps that have an ability to effectively pump water vapor over and beyond other devices. A cryopump system is suitable for applications that operate in the HV and UHV vacuum pressure ranges.

I picked an article about cryopump from internet for your further reference.
