DETAILED DESCRIPTION OF EMBODIMENTS

Introduction

[0038] As previously described, there is a need to conveniently and quickly cool down a beverage from room temperature to a desirable drinking temperature. Currently there are many cumbersome methods to accomplish this task. Some require filling a large vessel with ice and water and others are a bit more elaborate and involve rotating a beverage in cold water: a popular do-it-yourself method attaches a beverage to a drill and spins the beverage can in salted ice water, which has evolved into specialized drill bits designed for this purpose. There are also expensive commercial appliances that need to chill several cups of liquid before they are ready to cool a beverage. Other apparatus require the beverage to be transferred to another vessel and a subset of those that require an additional transfer to another glass. All these separate vessels require cleaning.

[0039] In accordance with the principals of the present invention, a beverage can cooler is provided that provides a low cost, convenient, and economical way of quickly cooling room temperature beverages in a can to a cold consumption temperature while avoiding the risk of over chilling or freezing the beverage. In accordance with the principals of the present invention, a frozen tube is adapted to securely surround the can, the frozen tube utilizing high heat capacity/thermal mass to wick heat from the beverage in the can. Contained within the frozen tube, a plurality of fins act as a heatsink; in an alternative aspect in accordance with the principles of the present invention, the heat sink could be utilized alone, in the absence of the frozen tube. The presence of the fins act as a heatsink by increasing convective, conductive, and radiative heat dissipation if used without the ice and conductive heat dissipation if used with the ice. Thus, the fins reduce need for high thermal heat capacity of previous designs.

[0040] The heatsink should be in close proximal connection with the can. In an aspect in accordance with the principals of the present invention, the heatsink can comprise a split design and define a hinge, allowing the heatsink to expand around the can and achieve sufficient contact pressure/surface area for condition between the two elements conducting thermal transfer. The split design can be closed-biased with the hinge around the outer diameter of the beverage can. A preferred placement of the hinge can be about 180 degrees from a slot (directly across the diameter), but the hinge could be contained at other suboptimal locations. The heatsink should be comprised on a material having good heat transfer capabilities, such as a conductive material like aluminum, copper, silver, gold, tungsten, diamond, cubic boron arsenide, graphite, and the like. The hinge can be a living hinge that can be extruded with the heatsink as part of a one piece manufacturing process, with the living hinge providing the closed bias.

[0041] Thus, the high thermal conductive heatsink is able to expand and clamp around the diameter of the beverage can. It is helpful to maintain surface contact with the walls of the beverage can and allowing the heatsink to expand and contract helps accommodate manufacturing tolerances both for the heatsink and slight variation in beverage can diameters. Also this clamping pressure lowers the thermal resistance between the two surfaces transferring thermal energy. A beverage can cooler in accordance with the principals of the present invention avoids use of a heatsink manufactured to a tight tolerance which would not be as effective in adjusting to different can tolerances and cost more to manufacture.

[0042] One of the main challenges of the heatsink design of the present invention is that to achieve best performance a large temperature differential is desired. In ideal conditions, the environment that the heatsink is in is below the freezing point of liquids (0 degrees C.). In this environment, the device will chill a room temperature beverage in minutes; however, there is a risk of over chilling and freezing the beverage. An additional modification in accordance with the principals of the present invention prevents over chilling and freezing the beverage by adding an additional amount of ice around the heatsink and removing it from the subzero environment. In this embodiment, the heatsink would be put in an insulating vessel, water would be added around the heatsink, and then frozen to form an ice block around the heatsink. When there is a desire to cool a beverage, the device would be removed from the subzero environment and put into a refrigerator or room temperature environment. The ice would continue to wick heat away from the heatsink, and the heatsink would wick heat away from the beverage until beverage was removed or the systems reached thermal equilibrium above the freezing point of the beverage. This reduces material cost, increases total thermal heat capacity, and eliminates the risk of freezing. This also uses conduction and a much quicker way to thermal transfer heat (vs convection or forced convection)

[0043] In one aspect in accordance with the principals of the present invention, the heatsink can be placed in a mold, filled with water, and frozen to prepare the frozen tube adapted to securely surround the can for use. Ice is one of the most practical materials to use because a user can fill tap water around the heatsink at room temperature and put it in the freezer to create ice around the surface area of the heatsink. Ice/water is also a low cost material and ready available. Ice has very high heat capacity and is inexpensive, but has low thermal conductivity; the heatsink increases the thermal transfer of the contents of the beverage to a cold mass of high heat capacity. The colder this thermal mass is the faster the thermal transfer takes place. The conductive heatsink helps dissipate the heat into the high thermal ice mass. The ice also allows the device to function in a non-subzero environment and can eliminate the risk of freezing the beverage. This cold mass can be stored in a freezer so that it is ready on demand.

[0044] By adding fin geometry, there is greater convection and radiation thermal transfer to the freezer. Utilizing a beverage can cooler in accordance with the principals of the present invention with the fins alone would work well if the beverage is chilled in a cold environment; whereas by utilizing a beverage can cooler in accordance with the principals of the present invention with ice surrounding the heatsink, chilling in a room temperature or refrigerator environment reduces the risk of over chilling and freezing the beverage. The thermal heat capacity of the cold mass could be calibrated to only withdraw enough thermal energy so as to chill and not freeze the beverage. For the heatsink to be expandable with low force in this embodiment, it is preferred that the ice is also split in two halves—or thin at the point of the hinge so the ice can be easily broken—with one block on each side of the hinged or living hinged element.

Conceptual Architecture

[0052] In more detail and referring to FIG. 1, a diagram of a frozen tube 10 adapted to securely surround a can is seen, according to an example embodiment in accordance with the principals of the present invention: FIG. 1A shows a diagram of a top view looking downward on the frozen tube 10; FIG. 1B shows a cross-sectional side view of the frozen tube 10. The frozen tube 10 is adapted to securely surround the can and uses high heat capacity/thermal mass to wick heat from the beverage.

[0053] Contained within the frozen tube 10 a plurality of fins 14 act as a heatsink 12. In an alternative aspect in accordance with the principles of the present invention, the heat sink 12 can be utilized alone, in the absence of the frozen tube. The presence of the fins act as a heatsink by increasing convective, conductive, and radiative heat dissipation if used in the absence of the frozen tube and conductive heat dissipation if used with the frozen tube. Thus, the fins 14 reduce need for high thermal heat capacity. Referring to FIGS. 2 and 3, a heatsink 12 adapted to be contained within the frozen tube 10 of FIG. 1 is seen, in according to an example embodiment in accordance with the principals of the present invention. The heatsink 12 should be in close proximal connection with the can.

[0054] FIG. 4 is a top view of an additional heatsink 12 adapted to be contained within the frozen tube 10 of FIG. 1, according to an additional example embodiment in accordance with the principals of the present invention. In this aspect in accordance with the principals of the present invention, the heatsink 12 can comprise a split design comprising two halves 16, 18 and define a hinge 21, allowing the heatsink 12 to expand around the can and achieve sufficient contact pressure/surface area for condition between the two elements conducting thermal transfer.

[0055] The hinge 21 can comprise a living hinge that can be extruded with the heatsink 12 as part of a one piece manufacturing process with the heatsink 12. The living hinge 21 can provide the closed bias. FIG. 5 is a close-up view of the heatsink 12 of FIG. 4 shown defining a channel slot 23 which, with the hinge 21 define the split design comprising two halves 16, 18. FIG. 6 is a close-up view of the heatsink of FIG. 4 showing the living hinge 21 which, with the channel slot 23 define the split design comprising two halves 16, 18. FIG. 7 is an isomeric view of the heatsink of FIGS. 4-6.

[0056] Referring to FIG. 8, a heatsink 12 according to an additional example embodiment in accordance with the principals of the present invention is seen placed in a heatsink mold 27 according to an example embodiment in accordance with the principals of the present invention detailed below. In addition to defining a channel slot 23 and a hinge 21, the heatsink 12 of FIG. 8 includes curved fins 14. The curved fins 14 are oriented as curving outwardly away from the channel slot 23 at one periphery of the heatsink 12 and inwardly towards the hinge 21 at another periphery of the heatsink 12. As detailed below with respect to FIGS. 14-16, analysis demonstrates that adding curves to the fins 14 increases the length of contact between the fin 14 and the ice while reducing the overall required diameter such that for the same surface area contact, the overall device can be smaller. The spirals of the curved fins 14 run in two different directions so that there can be two fins that hit each other to act as a hard stop so reduce stress and yield on the hinge. The curved fins 14 also provide a visual to assist in recognizing the parting line if the user opens the device to insert or remove the beverage can.

[0057] As previously described, in one aspect in accordance with the principals of the present invention, the heatsink 12 can be placed in a mold 27, filled with water, and frozen to prepare the frozen tube 10 adapted to securely surround the can for use. Ice has very high heat capacity and is inexpensive, but has low thermal conductivity. The conductive heatsink 12 helps dissipate the heat into the high thermal ice mass. The ice also allows the device to function in a non-subzero environment and can eliminate the risk of freezing the beverage.

[0058] FIG. 9 is perspective view of the mold 27 for the heatsink 12 with the heatsink removed. In the most ideal embodiment, the mold can be comprised of a suitable flexible material such as for example a silicone or thermoplastic elastomers. The mold 27 should provide a sufficient seal with the bottom of the heatsink to keep the water from entering the inside of the heatsink to position the ice around the outer periptery but not inwardly of the fins 14. Thus, in one aspect in accordance with the principles of the present invention the bottom floor 30 of the mold 27 defines an upwardly extending ridge 32 that acts as a seal with the interior of the heatsink 12. In an alternative aspect in accordance with the principles of the present invention, if a better seal is desired the bottom floor 30 can define a plurality of fin receptors into which the fins 14 of the heatsink 12 fit.

[0059] As previously described, the heatsink 12 can define a channel slot 23 which, in conjunction with the hinge 21 define the split design comprising two halves 16, 18, allowing the heatsink 12 to expand around the can and achieve sufficient contact pressure/surface area for condition between the two elements conducting thermal transfer. To facilitate the split design comprising two halves 16, 18, the mold 27 can define a channel slot indentation 36 and a hinge indentation 38. The channel slot indentation 36 and the hinge indentation 38 further defined fin slots 41 into which the fins 14 of the heatsink 12 adjacent to the channel slot 23 and the hinge 21 fit. This can be seen in FIG. 8.

[0060] In addition to defining a channel slot 23 and a hinge 21, the heatsink 12 of FIG. 9 includes curved fins 14. The curved fins 14 are oriented as curving outwardly away from the channel slot 23 at one periphery of the heatsink 12 and inwardly towards the hinge 21 at another periphery of the heatsink 12. As with the placement of the fin receptors 32 on the bottom floor 30 of the mold 27, placement of the fins 14 of the heatsink 12 adjacent to the channel slot 23 and the hinge 21 into the fin slots 41 of the channel slot indentation 36 and the hinge indentation 38 positions the ice round the outer periptery but not inwardly of the fins 14.

[0061] This can be seen in FIG. 10, which is a cross section of the heatsink of FIG. 9 placed in the heatsink mold of FIG. 8 with water or ice 43 added between the mold 27 and the heatsink 12. It is also seen that the channel slot indentation 36 and fin slots 41 into which the fins 14 of the heatsink 12 adjacent to the channel slot 23 fit have kept ice from forming at the slot indentation 36; likewise, the hinge indentation 38 and fin slots 41 into which the fins 14 of the heatsink 12 adjacent to the hinge 21 fit have kept ice from forming at the hinge 21, thus forming the ice block 43 further defining the split design comprising two halves 16, 18. This can best be seen in FIG. 11, which shows an exploded cut-away view of ice 43 formed around/within the heatsink with the mold removed.

[0062] FIG. 12 is perspective, cut-away view with the mold removed and holding a can 45 with a beverage being cooled while FIG. 13 is a cross section of the heatsink and mold of FIG. 9 with a can in place. The cross sectional view of FIG. 13 shows not only the block of ice 43 formed between the heatsink 12 and the mold 27 but also shows the ice 43′ formed in-between the fins 14.

[0063] To calculate the thermal and fluid interactions in a simulated environment of a beverage can cooler in accordance with the principals of the present invention, Computational Fluid Dynamics (CFD) and Computational Thermal Dynamics (CFD) analysis software was utilized. Heat transfer analysis was conducted between elements from initial starting temperature conditions to show the resulting temperature over time as the beverage cools and the ice melts.

[0064] To start, the geometry of a beverage can cooler in accordance with the principals of the present invention was created in 3-D Computer Aided Drawing (CAD) software and imported into CFD software. The material properties were applied with the necessary conductivity and heat capacity. Then, boundary conditions and temperature were assigned. The underlying equations of state were solved. These equations of state are related to the conductive heat transfer and natural convection in the fluid caused by thermal gradient and currents. Post processing tools such as planes and color plots were overlaid onto the model and the mesh to communicate the results. “Mesh” refers to the wireframe structure that is applied to the CAD model in the CFD analysis. The mesh is a serious of nodes and connection points. The simulation is run on each node to determine the temperature and fluid flow. The tighter the mesh, the more accurate the analysis.

[0065] To optimize the design of a beverage can cooler in accordance with the principals of the present invention, the fins are of a proper thickness and length to quickly transfer heat to the ice. The thickness of the base of the fins was chosen to properly extract heat from the outer surface of the can. The thickness of the fins was chosen to optimize the amount of heat being extracted from the base, and also optimize the amount of surface area with the ice. The gap between the fins (the thickness of the ice between the fins) was sized such that the ice goes through its phase change when the optimal temperature of the can has been reached. The profile consists of a specifically designed taper and curvature. To promote heat transfer due to conduction within the material of the device, the taper of the fins was designed to minimize the material while still keeping the fin thickness wide at the base. The curvature of the fins optimizes the surface area while minimizing the overall diameter of the device.

[0066] The volume of ice and thus the diameter of the mold were sized such that the ice goes through its phase change when the optimal temperature of the beverage has been reached. To account for variations in beverage starting temperature and freezer temperature/settings, the user can control the volume of water poured in to the device. For example, if the can is stored in a hot environment, then more water could be poured; contra wise, if the freezer temperature is colder, less water could be poured. The mold could have visual indicators (fill lines) corresponding to the appropriate temperature differentials between the can and the freezer.

[0067] Referring to FIG. 14, a graph of the CFD simulated average temperature of the beverage over time is seen: temperature is set forth on the vertical axis between 40 degrees and 80 degrees Fahrenheit; time is set forth on the horizontal axis between 0 and 300 seconds. It is seen that utilizing a beverage can cooler in accordance with the principals of the present invention reduces the average temperature from 75 degrees Fahrenheit to 45 degrees Fahrenheit in 300 seconds, or five minutes. The temperature profile of the beverage, can, and beverage can cooler of the present invention at 300 seconds can be seen depicted in the CFD software in FIG. 15; this is contrasted with the temperature profile of the beverage, can, and beverage can cooler of the present invention at 15 seconds, when the temperature of the beverage is approximately 70 degrees Fahrenheit, seen in FIG. 16.

[0068] While a beverage can cooler in accordance with the principals of the present invention has been described with specific embodiments, other alternatives, modifications, and variations will be apparent to those skilled in the art. For example, in the alternative embodiment where the heat sink is utilized alone, a fan could be added to provide forced convection. As an additional example, an electro-mechanical means could be added to induce agitation such as for example by spinning the can or rotating, stopping, and rotating the whole device in the opposite directions. Accordingly, it will be intended to include all such alternatives, modifications and variations set forth within the spirit and scope of the appended claims.
