Modular architecture for helium compressors

摘要

A modular architecture for helium compressors is described. In the modular architecture, oil is cooled independently from gas. In one aspect, the oil is cooled subsequent to the gas with a series of water-cooled heat exchangers. In another aspect, the oil is cooled using a water-cooled heat exchanger coupled to a radiator, and the gas is independently cooled using a refrigerant-cooled heat exchanger coupled to a condensing unit.

主权项

1. An oil-lubricated compressor system which compresses a monatomic gas and which comprises: a water-cooled heat exchanger for cooling oil, wherein the water-cooled heat exchanger is coupled to a radiator for circulating cooling water therebetween in a first closed cycle; and a refrigerant-cooled heat exchanger for cooling the gas, wherein the refrigerant-cooled heat exchanger is coupled to a condensing unit configured to condense and cool a refrigerant in a second closed cycle, wherein said water-cooled heat exchanger is thermally isolated from said refrigerant-cooled heat exchanger to allow said water-cooled heat exchanger and said refrigerant-cooled heat exchanger to operate at separate temperatures.
