DESCRIPTION OF THE PREFERRED EMBODIMENT

[0020] The current invention is a self-cooling cooler device 1 as shown in FIGS. 1 through 5. The present invention combines a miniaturized version of absorption refrigeration with a traditional container such as an ice chest/cooler 100.

[0021] The ice chest/cooler 100, as shown in FIGS. 1 and 3, has a body with a lid 120 and handles 110 at the sides. The lid 120 is attached to the body by hinges 130 in the back. The lid 120 will open up to the storage cavity in the cooler 100.

[0022] The current invention, in the preferred embodiment, has a cooling system created by the combination of an absorption refrigeration system 10 with the ice chest/cooler 100 as shown in in FIG. 2. The refrigeration system 10 is connected to the body of the cooler 100 using connection means 30 such as screws or an adhesive means. The refrigeration system 10 keeps the inside of the cooler 100 cool.

[0023] In the preferred embodiment, the absorption refrigeration system 10 uses an ammonia solution, due to its low boiling point.

[0024] The boiler in the present invention's preferred embodiment absorption refrigeration is fired by a vaporizer, powered by a rechargeable battery. There are absolutely no moving parts, and the unit is totally self-contained. With the use of a thermostat, the cool time can be as long as the life of the vaporizer.

[0025] The charging of the rechargeable battery, such as an Ni-Cad battery, can be as simple as the use of a mini USB plug or a solar panel. The vaporizer does not require much power for the low boiling rate of the ammonia solution. The ammonia solution lasts forever and can be reheated indefinitely. The applications are vast and varied.

[0026] The Coolers/ice chest 100 can be for recreational use or for use in vehicles to cool cup holders to keep things cool. With the use of the solar panels for recharging, the user could use this in impoverished countries for cooling and several applications in between. The present invention can use low voltage heat strips to fire the adsorption refrigeration system 10. The actual boiling point of the ammonia solution, which is what is heated, is very low, just over 100 degrees.

[0027] This is found in every RV that has a refrigerator. The only difference in the absorption system that the present inventor described, is in a traditional system, propane is used to heat the boiler. In the present invention, the vaporizer is used to heat the boiler, replacing the open flame that the propane requires. The absorption refrigeration system 10 is totally self-contained.

[0028] An absorption refrigerator is a refrigerator that uses a heat source (e.g., solar energy, a fossil-fueled flame, waste heat from factories, or district heating systems) to provide the energy needed to drive the cooling process. The vapor absorption refrigeration system 10 comprises of all the processes in the vapor compression refrigeration system like compression, condensation, expansion and evaporation. In these systems the refrigerant used is ammonia, water or lithium bromide. The refrigerant is condensed in the condenser and evaporated in the evaporator 20. After this the refrigerant produces a cooling effect in the evaporator and releases the heat to the atmosphere via the condenser. In vapor absorption systems, the energy input is given in the form of heat.

[0029] The invention can further be coupled with a solar panel for recharging the battery so as to power the vaporizer and be used in impoverished countries for cooling and refrigeration purposes as well as for several other applications.

[0030] There are a number of significant design features and improvements incorporated within the invention.

ADVANTAGES

[0031] The current invention is portable, completely self-contained, and convenient. The container does not need ice, is always cold and uses an absorption refrigeration system.

[0032] Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions are possible. Therefore, the point and scope of the appended claims should not be limited to the description of the preferred versions contained herein.

[0033] As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. With respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0034] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
