ABSTRACT:
Fibrous material disposed in the Joule-Thomson orifice and/or the high pressure tube of a Joule-Thomson heat exchanger provides an effective flow restrictor in the orifice and means to prevent blockage because of contaminants in the fluid freezing and clogging the orifice. A Joule-Thomson device of this type can be fabricated for use as a cryostat to be disposed in confined space.
