Closed-Cycle Cryogenic Refrigeration System

摘要

A multi-stage closed-cycle cryogenic refrigeration system is disclosed. The system includes an adsorption refrigerator having a multi-chambered pump unit that can be flexibly configured in the context of the cryogenic refrigeration system resulting in a more efficient design that has a smaller overall size than prior systems and other advantages.
