Title:
THERMAL INSULATION VESSEL
Document Type and Number:
WIPO Patent Application WO2000073624
Kind Code:
A9
Abstract:
A thermal insulation vessel is provided that includes a first housing has a first internal cavity and an inner wall. A first plurality of magnets are coupled to the first housing and positioned proximate the inner wall in circumferentially spaced-apart relation. A second housing is positioned in the first internal cavity and has a second internal cavity and an outer wall. A second plurality of magnets is coupled to the second housing and positioned proximate the outer wall in circumferentially spaced-apart relation. The second plurality of magnets interacts with the first plurality of magnets to maintain a gap between the inner wall and the outer wall. The vessel may be used to thermally isolate components within or for use with various downhole tools. Magnetic levitation eliminates most and possibly all pathways for conductive heat transfer.
