Abstract
A shaped article is capable of at least one of containing and delivering a cryogenic fluid. The article has a porous structure that restricts the passage of cryogenic fluid in the liquid phase while permitting the passage of cryogenic fluid in the gaseous phase. The article may be in the form of a tube or container. The article permits a liquid cryogen to be transported to a specific site, and then cool the site by means of conduction from the cold article and convection of cold gas, the phase change of the evaporating liquid greatly enhancing the heat loss.
Claims2
A method of controlling the evaporation of a cryogenic fluid comprising transporting said fluid through a shaped article, said shaped article having a porous structure and a liquid nitrogen leak pressure of greater than or equal to about 0.3 psi.
A method of controlling the evaporation of a cryogenic fluid comprising transporting said fluid through a shaped article comprising a polymer, said shaped article having a porous structure that restricts the passage of cryogenic fluid in the liquid phase while permitting the passage of cryogenic fluid in the gaseous phase.
