Abstract
A cold-gas coolant nozzle which limits the amount of turbulence induced in the flow of cold gas due to interaction with ambient air by creating a intermediate temperature buffer zone between the cold gas and the ambient air.
Claims16
A nozzle for delivering a coolant stream to a location within an ambient atmosphere, comprising
- a vacuum jacket,
- a tubular cavity set primarily within said vacuum jacket, comprising an inlet, an outlet, and an outer surface, and
- a heater within said vacuum jacket, wherein said heater is in conductive thermal contact with said outer surface of said tubular cavity.
A method of delivering a coolant stream to a location within an ambient atmosphere, comprising the steps of
- directing a coolant stream into the inlet of a tubular cavity, wherein said tubular cavity comprises an inlet and an outlet, and wherein said tubular cavity is primarily enclosed by a vacuum jacket,
- orienting said tubular cavity to direct the coolant stream exigent from said outlet of said tubular cavity at the desired location within the ambient atmosphere, and
- heating the outer zone of said coolant stream within said tubular cavity and near said outlet of said tubular cavity.
