Abstract
An apparatus for cooling a containerized fluid apparatus has a refrigerant-delivery assembly axially depending from a handle assembly. The handle assembly forms a receptacle for receiving a canister of refrigerant such as pressurized liquid carbon dioxide (CO2). The refrigerant-delivery assembly comprises a supply tube through which refrigerant is fed from the canister in the handle assembly to a refrigerant-containment compartment enclosing an exit port of the supply tube and entry ports of one or more expansion tubes. The refrigerant-containment compartment places the supply tube in fluid-flow communication with the expansion tubes. The expansion tubes are rotatable about the axis of the supply tube. The expansion tubes are made to rotate by either a nozzle-turbine feature or a motor-and-gear subassembly. As refrigerant expands in the expansion tubes it takes on heat in accordance with thermodynamic properties thereby cooling the containerized fluid.
