System and method for cooling which employs charged carbon dioxide snow
A method and system acts to cool matter through the use of a carbon dioxide snow/vapor flow. The matter is supported in juxtaposition to an outlet for the carbon dioxide snow/vapor and a conductor which exhibits a reference potential state. To perform the method, a flow of liquid carbon dioxide is s...

| description | A method and system acts to cool matter through the use of a carbon dioxide snow/vapor flow. The matter is supported in juxtaposition to an outlet for the carbon dioxide snow/vapor and a conductor which exhibits a reference potential state. To perform the method, a flow of liquid carbon dioxide is subjected to a pressure expansion to create a flow of carbon dioxide snow and vapor. The carbon dioxide snow and vapor then come into contact with a conductive surface and achieves a charge as a result of frictional engagement with the conductive surface. Thereafter, the carbon dioxide snow/vapor is directed towards the matter to be cooled and the conductor which exhibits a reference potential. The reference potential state attracts the carbon dioxide snow and aids in contact thereof on the matter being cooled. |
