Cryogenic fluid circuit design for effective cooling of an elongated thermally conductive structure extending from a component to be cooled to a cryogenic temperature

摘要

The cryogenic system includes a cryogenic chamber housing, a cryogenic chamber cooling source, and a circulation loop that circulates the cryogenic liquid between the cooling source and components that are cooled in the cryogenic chamber. The component is a thermally conductive structure that stretches and extends in a warm environment. For the cooling control of the structure, the inlet stream of cryogenic liquid is connected along the length of the structure in which it is extended, the stream is separated into a first outlet stream at a first location of the part and at a second location And the control valve regulates the fraction of the inlet stream to be the second outlet stream.
