Abstract

An apparatus and method are provided for rapidly cooling small volumes of fluids. The apparatus includes a plurality of cooling elements each including a housing forming a sealable cooling fluid chamber which can house a cooling fluid. At least one spacer is arranged to separate opposed cooling elements and provide a separation distance between the opposed cooling elements. Each of the plurality of cooling elements is arranged to be independently separable to allow ready assembly, disassembly, and cleaning. The plurality of cooling elements can include a stack of disc-shaped cooling elements or concentric cylinders that can be situated in a container and rotated by a motor.

Claims

1. A rapid fluid cooling apparatus comprising:

a plurality of cooling elements, each of the cooling elements including a housing forming a sealable cooling fluid chamber capable of containing a cooling fluid;

at least one spacer separating opposed cooling elements and providing a predetermined separation distance between the opposed cooling elements when the cooling elements are secured in an operable position; and

a container capable of receiving the plurality of cooling elements and holding a liquid to be cooled;

wherein each of the plurality of cooling elements are arranged to be independently separable.

2. The rapid fluid cooling apparatus of claim 1, wherein a mean separation distance between opposed cooling elements is less than about 1 cm.

3. The rapid fluid cooling apparatus of claim 2, wherein the mean separation distance between opposed cooling elements is about 2 mm to about 3 mm.

4. The rapid fluid cooling apparatus of claim 1, wherein the cooling fluid chamber of at least one of the cooling elements includes a heat-conducting fin.

5. The rapid fluid cooling apparatus of claim 1, wherein the plurality of cooling elements includes a stack of disc-shaped cooling elements.

6. The rapid fluid cooling apparatus of claim 5, further comprising a container into which the plurality of disc-shaped cooling elements is capable of being removably inserted.

7. The rapid fluid cooling apparatus of claim 6, further comprising a motor arranged to rotate the plurality of disc-shaped cooling elements when inserted in the container.

8. The rapid fluid cooling apparatus of claim 1, wherein the plurality of cooling elements includes at least two concentrically arranged cylinders.

9. The rapid fluid cooling apparatus of claim 8, wherein the plurality of concentric cylinder cooling elements is capable of being removably inserted into the container.

11. The rapid fluid cooling apparatus of claim 1, wherein the plurality of cooling elements includes at least two planar plates arranged substantially parallel to one another.

12. The rapid fluid cooling apparatus of claim 6, further comprising surface undulations or projections arranged on one or more surfaces of at least one of the plurality of cooling elements capable of generating turbulence during rotation of the cooling element.

10. A rapid fluid cooling apparatus comprising:

a plurality of cooling elements, each of the cooling elements including a housing forming a sealable cooling fluid chamber capable of containing a cooling fluid, the plurality of cooling elements including at least two concentrically arranged cylinders;

at least one spacer separating opposed cooling elements and providing a separation distance between the opposed cooling elements;

a container into which the plurality of cooling elements is capable of being removably inserted; and

a motor arranged to rotate the plurality of cooling elements when inserted in the container;

wherein each of the plurality of cooling elements are arranged to be independently separable.

13. A method of rapidly cooling a fluid comprising:

providing a plurality of cooling elements, each of the cooling elements including a housing including a sealed cooling fluid chamber filled with a cooling fluid, each of the cooling elements being spaced apart from an opposed cooling element at a predetermined separation distance and being independently separable from the other cooling elements;

reducing the temperature of the plurality of cooling elements by exposing the cooling elements to a reduced temperature;

arranging the cooling elements in a container; and

pouring a fluid to be cooled into the container.

14. The method of claim 13, wherein each of the opposed cooling elements are spaced apart by less than about 1 cm.

16. The method of claim 13, further comprising pouring the fluid to be cooled from the container after the fluid has been cooled by the cooling elements.

18. The method of claim 13, wherein reducing the temperature of the plurality of cooling elements includes freezing the cooling fluid housed in each of the plurality of cooling elements.

19. The method of claim 13, wherein the plurality of cooling elements includes a stack of opposed disc-shaped cooling elements.

20. The method of claim 13, wherein the plurality of cooling elements includes at least two concentrically arranged cylinders.

15. A method of rapidly cooling a fluid comprising:

providing a plurality of cooling elements, each of the cooling elements including a housing including a sealed cooling fluid chamber filled with a cooling fluid, each of the cooling elements being spaced apart from an opposed cooling element and being independently separable from the other cooling elements;

reducing the temperature of the plurality of cooling elements by exposing the cooling elements to a reduced temperature;

arranging the cooling elements in a container;

pouring a fluid to be cooled into the container; and

rotating the plurality of cooling elements within the container.

17. A method of rapidly cooling a fluid comprising:

providing a plurality of cooling elements, each of the cooling elements including a housing including a sealed cooling fluid chamber filled with a cooling fluid, each of the cooling elements being spaced apart from an opposed cooling element and being independently separable from the other cooling elements;

reducing the temperature of the plurality of cooling elements by exposing the cooling elements to a reduced temperature;

arranging the cooling elements in a container;

pouring a fluid to be cooled into the container;

pouring the fluid to be cooled from the container after the fluid has been cooled by the cooling elements; and

placing a cleaning solution into the container and rotating the plurality of cooling elements.
