CELLULAR INSULATION FOR USE WITH LOW TEMPERATURE LIQUIDS

摘要

Capillary insulation for low temperature liquids in which a cellular structure defines a plurality of discrete cells enclosed by a capillary cover with capillary openings communicating with each cell. The cell walls and the cover are designed to minimize the effects of strains imposed thereon by providing an excess of material both in the walls and the cover thereby permitting them to deflect without adversely affecting operation of the insulation. The cell walls are formed in an S-shaped configuration and the cover is dimpled to provide the desired excess material. The capillary openings are reinforced by a toroidal rib extending around each opening.
