As is therein shown, the liner member 134 is disposed concentric with the HEU wall 1 32 and surrounds the inner surface 1 36 of the HEU wall 1 32 to facilitate the flow of gas 1 30 throughout the HEU 1 6.

  • the ribs 1 38 may alternatively be spiraled to form a series of channels which are spiraled along the length of the wall 1 32 of the HEU 16.

  • the dimensions of the ribs 1 38 and channels 142 will vary depending on factors, including but not limited to the dimensions of the HEU 1 6 in which the liner member 1 34 is used and the dimensions of the container 1 2 the HEU 1 6 is designed to cool.
  • the container is inverted or disposed upside down as is illustrated in FIG. 10 and the HEU 1 6 is activated via the portion of the valve stem 24 which projects axially beyond the assembly 10 of the container 1 2.
  • the pressure on the liquefied gas 1 30 in the chamber 1 28 decreases which causes the liquefied gas 1 30 to flow into the bottom 1 31 of the chamber 1 28.
  • the initial heat transfer between the beverage 1 26 and the liquefied gas 130 occurs within the plurality of channels 142. Heat from the beverage 1 26 is absorbed by the liquefied gas 1 30 through the wall 1 32 of the chamber 1 28 as the liquefied gas 1 30 vaporizes by means of adiabatic expansion.
  • the liquefied gas 1 30 begins to boil causing bubbles which are pumped upward into the channels 142. This boiling action thus propels the liquefied gas 1 30 upward into the channels 1 42 and causes virtually the entire interior surface area of the HEU wall 132 to be bathed with liquefied gas, even as the liquefied gas 1 30 level drops down to small amounts. For example, even when the level of the liquefied gas 1 30 drops to a quarter of an inch, the liquefied gas 1 30 will continue to be pumped up and bathe virtually the entire interior surface area of the HEU wall 132.
  • pressurized container is inside a beverage container surrounded by the beverage, there is a portion of the surface on the side of the pressurized container in contact with the beverage where little heat transfer is taking place because evaporated gas is immediately on the other side of the skin of the container.
  • the liner into the pressurized container, essentially the entire surface area on the sides can be kept to transferring heat until nearly all the liquefied gas has been evaporated. Since evaporation can only occur where the required heat is available, evaporation on the sides will only occur in the vertical channels.
  • the gas that is generated forms bubbles which travel up the channels to the top. When they burst, the gas collects in the top of the container and eventually exits out the valve opening to the atmosphere. As the gas bubbles travel upward, they carry liquefied gas with them, thus keeping the entire side wall bathed with liquefied gas regardless of the liquefied gas level in the container. The entire side of the wall remains effective throughout the heat transfer process. As liquefied gas evaporates, it is replaced by liquefied gas flowing into the bottom of the channels. The net result is a significant decrease in the time required to chill the beverage.
  • the present invention when a mixture of gases is desired, does not require the gases to azeotrope because of the local agitation that occurs. In other words, as a result of the bubbling which occurs and the isolation of the evaporation process, a mixture of gases will still evaporate and maintain their initial percentages throughout the evaporation process without having to be azeotropic.
  • the valve stem 24, when reciprocated axially will open and close the valve 22 to allow the gas to discharge through the stem 24.
  • the container 1 2 is as illustrated in FIG . 10, inverted or positioned upside down, such that the assembly 10 of the container 12 is exposed for activation.
  • valve 22 In a typical operation, when the valve 22 is closed, i.e., when an elastomeric ring or gasket covers the openings in the valve stem 24, the chamber 1 28 is sealed and neither the liquefied or evaporated gas 1 30 can escape from the HEU 16.
  • the actuator mechanism When the actuator mechanism is activated, it contacts the valve stem 24 and causes the valve stem 24 to move upwardly relative to the elastomeric ring. Valve designs are also possible wherein the actuator mechanism causes lateral displacement of the stem 24 in the gasket which allows gas to flow. When the stem 24 is moved up, the openings are no longer blocked by the elastomeric ring or gasket and fluid communication is established between the gas in the chamber 1 28 and the axial passageway in the stem 24.
  • HEU 1 6 absorbs heat from the beverage through the external wall of the HEU 16 which is preferably formed from a heat conductor like aluminum.
  • the gas 1 30 flows through the passageway and is ultimately exhausted from the container 10 through the opening produced by valve stem 24.
