Methods and apparatus for recycling cryogenic liquid or gas from test chambers |
摘要 |
Methods and apparatus are presented which allow efficient environmental testing of components such as printed circuit boards, integrated circuits, sub-systems and other components. In one method of the invention, a component can be placed into a chamber having an internal space filled with a gaseous atmosphere. The component is indirectly cooled by smartly positioning one or more cooling coils near the component to be tested, and the cooling coils are fed with a cryogenic fluid from a source of cryogenic fluid. The warm cryogenic fluid is recycled by one of two means: a thermosiphon conduit loop, and a storage and compression facility for reusing the warm cryogenic fluid. The internal space is preferably filled with a dry gas.
