Claims
- 1. Apparatus for cooling a medium located within a chamber of a container defined by a container wall, the container wall having interior and exterior surfaces, the chamber being defined by the interior surface of the container wall, the medium being located within the chamber and in contact with the interior surface, the container wall providing means for transferring heat energy from the interior surface to the exterior surface, the apparatus comprising:
- an evaporation unit having liquid operating medium therein and a connection port, the exterior surface of the container being in contact with the liquid operating medium of the evaporation unit,
- a sorption medium container having at least first and second connection ports and sorption medium therein, the sorption medium being capable of adsorbing and desorbing the liquid operating medium vapor, the container being oriented over the sorption medium container such that the connection port of the evaporation unit and a portion of the exterior surface of the container are disposed adjacent and operatively coupled to the first connection port of the sorption medium container,
- vacuum means, the vacuum means being coupled to the second connection port of the sorption medium container such that sorption medium is interposed between the point at which the evaporation unit and sorption medium container are coupled and the point at which the vacuum means and the sorption medium container are coupled, the vacuum means providing means for drawing evaporated liquid operating medium down and through the sorption medium,
- wherein when a portion of the liquid operating medium evaporates, the liquid operating medium vapor is absorbed by the sorption medium causing the temperature of the liquid operating medium to decrease, and wherein heat energy is transferred from the medium within the container to the container wall, the operating medium absorbing the heat energy from the container wall so as to lower the temperature of the medium within the container.
- 2. Apparatus for cooling a medium located within a chamber of a container as defined by claim 1 wherein the evaporation unit is contained within an exterior chamber of the container.
- 3. Apparatus for cooling a medium located within a chamber of a container as defined by claim 2 wherein the liquid operating medium is bound in an absorption-like material having a surface which engages at least a portion of the exterior surface of the container.
- 4. Apparatus for cooling a medium located within a chamber of a container as defined of claim 1 wherein the sorption medium is removable from the sorption medium container.
- 5. Apparatus for cooling a medium located within a chamber of a container as defined of claim 1 wherein the container to be cooled is a bottle into which a liquid medium may be enclosed.
- 6. Apparatus for cooling a medium located within a chamber of a container as defined of claim 1 wherein the evaporation unit is coupled to the sorption medium container in an air-tight manner.
- 7. Apparatus for cooling a medium located within a chamber of a container as defined by claim 1 wherein the sorption medium is zeolite.
