COMPACT CRYOGENIC LIQUEFACTION SYSTEM

摘要

A compact desktop gas liquefaction system having a gas generator, a cooling unit having a Stirling, pulse-tube or Stirling-pulse-tube cooler, and an insulated container to receive the liquefied gas. The system may be used to produce liquid nitrogen, oxygen, argon, natural gas, or air. The insulated container can be quickly disengaged from the gas liquefaction system, thereby minimizing the risk associated with handling liquefied gases. This compact liquefier allows for on-demand and on-site cryogen generation. The system provides a condenser surrounded by an evacuated space for greater efficiency of operation in a limited space.
