Description
BACKGROUND OF THE INVENTION
1. Field of the Invention

This invention relates to the field of providing cooling temperatures to portable units such as insulated or non-insulated ice chests or coolers. These various items are intended for portable use where the product will be taken by individuals to locations which do not have electricity connections and which do not have conventional methods for refrigerating items such as food, beverages, medical supplies, blood, organs, temperature sensitive chemicals and pharmaceuticals, any prey resulting from fishing or hunting activities or any other perishable items in need of refrigeration, cooling or freezing for a desired period of time.


2. Description of the Prior Art

Methods for cooling items with no ices or available electricity have been known in the prior art but the apparatus and method to maintain controlled temperatures utilizing liquid and/or gaseous CO2 as a refrigerant has not been found in any prior art. Therefore, there is a significant need for an improved apparatus and method to keep objects in a cool or even frozen condition depending upon the object and its requirement for its temperature control and the length of time it must be in the cooler or frozen condition.


The following prior art is the closest prior art which the present inventors have located and is the closest prior art to the best of the present inventors' knowledge related to the present inventors' invention.

    • 1, U.S. Pat. No. 4,096,707 for “PORTABLE REFRIGERATION MACHINE” issued on Jun. 27, 1978 to Taylor.


The patent discloses a portable refrigeration machine that includes a vertically oriented pressure vessel containing carbon dioxide in gaseous, liquid and/or solid states. A heat exchanger is secured to the lower external portion of the vessel and an outer housing surrounds the vessel to leave an annulus between the exterior wall of the vessel and the interior wall of the housing. A gas pressure operated fan is disposed beneath the heat exchanger and connected for operation by gas pressure from the vessel to rotate. The fan draws in air through appropriate lower inlet openings which air passes through the heat exchanger and annulus out outlet opening to thereby cool and circulate the air in a compartment within which the portable refrigeration machine is placed. This device utilizes a gas pressure operated fan to maintain temperature and dispose heat to provide room for cool air.


This patent discloses fan-technology for use as a coolant and this is completely different from the present invention.

    • 2. U.S. Pat. No. 4,195,491 for “DRY ICE REFRIGERATOR” issued on Apr. 1, 1980 to Roncaglione.


The patent discloses an apparatus for converting a conventional insulating picnic cooler or the like into a refrigerator and includes a small container, disposable within the cooler, for dry ice. A rectangular frame insertable within the interior of the cooler includes a pair of refrigeration coils, which are disposed in proximity to opposed side walls of the cooler. One end of each of the coils connects to the dry ice container. The other end of the coils connects to a manually adjustable valve having a pressed blowout section for relieving excess pressure. The valve is disposed in the exterior of the container. Gas flowing through the valve from the coil passes to the atmosphere through an indicator having a body of fluid in a transparent window so that bubbles produced upon passage of the gas are visible and allow manual adjustment of the valve to control the rate of gas flow and thus the rate of sublimation of the dry ice and the temperature within the cooler.


This device utilizes a valve controlled release in order to perform functions of maintaining temperature but has many deficiencies including the inability to monitor and maintain a specific temperature and no ability to be handled remotely. Therefore, the disclosure in this patent is different from the present invention.

    • 3. U.S. Pat. No. 4,404,818 for “CO2 SNOW COOLER WITH SNOW SPLITTING BOTTOM” issued on Sep. 20, 1989 to Franklin, Jr.


The patent discloses a vertically elongated hollow housing including opposite generally parallel side and end walls is provided and closed at its top by a top wall. CO2 snow forming structure is disposed in an upper portion of the interior of the housing and a bottom wall structure closes the lower portion of the housing. The bottom wall structure includes an elongated horizontally disposed inverted V-shaped wedge of sharply tapered configuration extending between the end walls of the housing and the wedge is functional to split the lower portion of a quantity of snow disposed within the housing above the wedge and to force the lower portions of the quantity of snow into full surface-to-surface heat transfer relation with the inner surfaces of the lower portions of the side walls of the housing horizontally aligned with and opposing the wedge as the quantity of snow sublimes. Further, the sidewalls of the housing include vertically extending corrugations functioning to at least substantially double the exposed inner and outer surface area of the sidewalls. The corrugations themselves are trapezoidal in cross section whereby substantially full surface to surface contact between the lower portions of a quantity of CO2 snow disposed within the housing and the inner surfaces of the corrugated side walls thereof is assured.


The disclosure in this patent utilized CO2 to produce snow and it is not a device designed to keep items refrigerated under a controlled temperature.

    • 4. U.S. Pat. No. 7,386,995 for “DEVICE FOR PRODUCING DRY ICE AND PRESSURE RELIEF THEREOF” issued on Jun. 17, 2008 to Gomes et al.


The patent discloses a device for producing a solidified block of carbon dioxide and includes first and second housing portions removably connectable together. The first and second housing portions form an interior molding chamber that is adapted to receive liquid carbon dioxide at a pressure where expansion of the liquid carbon dioxide occurs, resulting in a mixture of solidified and gaseous carbon dioxide. A pressure relief device includes a biasing member for biasing the first and second housing portions together. The biasing member permits relative movement between the first and second housing portions when internal pressure from the gaseous carbon dioxide exceeds a predetermined amount. With this arrangement, relative movement between first and second housing portions causes gaseous carbon dioxide to be released from the interior molding chamber to thereby reduce the internal pressure. This device utilizes liquid CO2 for the only purpose of producing dry ice, which can be used to refrigerate items, and, it is not a device designed to keep items refrigerated under a controlled temperature.

    • 5. United States Patent 20120138848 for “COOLING AGENT FOR COLD PACKS AND FOOD AND BEVERAGE CONTAINERS” published on Jun. 7, 2012 to Leavitt et al.


The patent discloses a safe, stable, non-toxic and recyclable cooling compositions comprising solid particulate compounds that undergo an endothermic process when mixed with water such that the resulting mixture is useful for cooling surfaces, liquids and solids. The compositions always include one or more compounds from a group consisting of endothermic compounds that contain potassium; one or more compounds from a group of endothermic compounds that contain nitrogen; and at least one compound from a group consisting of ammonium phosphate, diammonium phosphate, ammonium polyphosphate, ammonium pyrophosphate and ammonium metaphosphate such that the compound or mixture of compounds in this group is at least 1% by weight of the final composition.


This method disclosed in this patent utilizes a mixture of several compounds to cool any given surface, solid or liquid. The present invention does not require this complicated process of using several compounds which itself could lead to many errors and problems.

    • 6. U.S. Pat. No. 6,925,834 for “PORTABLE COOLER INCLUDING ICE SHEET HAVING REFRIGERANT CUBES” issued on Sep. 13, 2003 to Fuchs.


The patent discloses a portable cooler having one or more ice sheets including built-in refrigerant cubes. The cooler comprises an outer fabric shell and one or more sets of spaced apart refrigerant cubes encapsulated in plastic to form ice sheets that are attached to the interior walls of the cooler. The walls of the cooler may also include one or more layers of thermal insulation. The ice sheets provide a visually pleasing appearance to the inside of the cooler suggestive of cooling effects. The ice sheets may be retained along the walls of the cooler by seams sewn along the lanes passing between the refrigerant cubes, by being retained in pockets formed by sidewall liners or be being secured into chambers defined by the cooler's outer walls and a plastic insert fitted into the cooler.


This device utilizes ice sheets and the need to replace them as called for, with the temperature being maintained by manner of the insulated ice sheets.

    • The present invention does not use ice sheets and this disclosure is totally different from the present invention.
    • 7. “CO2ler” is a product that has been identified on the Internet. However, the inventors' research and investigation into this product did not find any related patent. This product is a cooler that has been specially made to have a closed compartment for one CO2 tank. The CO2 system used in the “Co21er” utilizes one tank only and it is not a device designed to keep items refrigerated under a controlled temperature.


None of the prior art has a method of system or apparatus to prevent or stop any freezing of an item or the freezing of an area.


None of the prior art has a method of system or apparatus to prevent the forming of the dry-ice while allowing the continuous flow of the CO2 thus preventing dry-ice.


None of the prior art has the ability to control or regulate the temperature of items or areas to be limited to cooling or maintaining a predetermined temperature and preventing the decrease in temperature with the prior art methods or systems to prevent freezing of items or areas intended for the reduction or refrigeration of.


The use of CO2 as a refrigerant in portable refrigeration similar to the present invention has previously been limited to the use of “dry ice”. Dry ice has several drawbacks including: 1) production of dry ice from liquid CO2 is relatively inefficient and a significant amount of CO2 is wasted during the process, 2) the temperature of dry ice is too low to be used in direct contact with many items that require refrigeration temperature, 3) dry ice must be stored in an insulated container, as it sublimates at room temperature, reducing the dry ice's effective cooling capacity over time, 4) dry ice can be a safety hazard as its inherent temperature at atmospheric pressure can cause frostbite almost instantly.


There is a significant need for an improved apparatus and method to utilize CO2 as a coolant in various applications.







SUMMARY OF THE INVENTION

The present invention is a standalone and self-contained cooling system using compressed liquid and/or gas CO2 containers positioned in an insulated or non-insulated vessel and consisting of a specially designed unit where the containers are vertically positioned in an upright or in an upside-down position. The liquid and/or gas CO2 coolant is then released into capillary tube(s) embedded into a heat transfer plate or heat exchanger thus leveraging the CO2 coolant properties.


The temperature is controlled by a metering CO2 releasing system encompassing an electronic control device which can be operated remotely and/or via a touch screen and which sends alerts when pre-defined thresholds are exceeded.


The invention's metering CO2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid. The invention's cooling system also encompasses check valves, which avoid liquid and/or gas CO2 from escaping when removing or replacing CO2 containers individually.


The present invention consists of self-contained cooling system(s) using compressed liquid and/or gas CO2 as coolant to refrigerate, cool or freeze items inside a portable insulated or non-insulated vessel. The present invention is capable of providing a controlled, steady and constant flow of liquid and/or gas CO2 thus maintaining the items in need to be refrigerated, cooled or frozen at the desired temperature.


The present invention relates to the field of providing a source of cooling to desired temperatures going from cool to cold to freezing depending upon the product which is desired to be kept cold within the cooler or ice chest.


This invention relates to the field of providing constant and controlled cooling temperatures to various items using refillable CO2 canisters as refrigerant without the necessity of electricity and without the necessity of having to have a built-in cooling unit within the container.


The following words: a) canister, b) cylinder, c) cartridge and d) tank are used interchangeably throughout this text to indicate the CO2 refillable container.


The following words: a) release valve, b) control valve and c) dispense valve are used interchangeably throughout this text to indicate the releasing member allowing the liquid and/or gas the CO2 to be distributed into the invention's cooling system in a controlled manner.


It has been discovered that the present invention provides the following advantages for using liquid CO2, among the advantages including 1) liquid CO2 is storable at standard ambient conditions, 2) cooling capacity does not degrade with length of storage, 3) there is no residual liquid CO2 after cooling capacity is exhausted, 4) temperature is continuously variable from ambient to below −40° F. allowing, for example, to maintain ice cream frozen or to keep organs at a constant temperature for transplant transportation, 5) coolant is easily replaced without the need to remove material from the container volume, 6) CO2 containers and refilling of CO2 containers are already commonly available (e.g. beverage and paintball industry), 7) CO2 is not wet or easily spillable as it is in a pressurized container.


The invention's cooling system is comprised of: a) one or more compressed liquid and/or gas CO2 container(s); b) a heat exchanger plate connected to a manifold block; c) capillary tube(s) embedded in the heat exchanger plate to allow the coolant to be distributed homogenously along the said heat exchanger plate; d) a manifold block where the CO2 container(s) is/are screwed into or attached on; e) check valves which are used to avoid CO2 from escaping when removing or replacing containers individually; f) a metering CO2 control releasing system and a control algorithm for controlling, monitoring and regulating, automatically or manually, the release of the liquid and/or gas CO2 inside the invention's cooling system; g) a control valve, as part of the metering CO2 control releasing system, which releases the liquid and/or gas CO2 in the capillary tube(s) and which has been specifically customized to prevent freezing, clogging and blocking of the capillary tube(s) by calibrating the optimal flow of liquid and/or gas CO2; the control valve may be electronically, thermostatically, manually or electromechanically operated; h) an electronic unit to operate the invention's metering CO2 control releasing system which may be operated using a touch screen or, remotely, using a smartphone application or any other electronic devices; the invention's cooling system has different variations according to the type of release valve and to the number of CO2 container(s).


The liquid and/or gas CO2 containers are positioned in the invention vertically in an upright or upside-down position.


When the CO2 container(s) is/are in an upright position, the invention's control valve has a siphon tube of a suitable length to be able to reach the bottom of the CO2 container. The siphon tube allows the liquid CO2 to flow from the bottom to the top of CO2 container and then to exit through the invention's control or release valve.


When the CO2 container(s) is/are in an upside-down position, because of the gravity force, the liquid or gaseous CO2 flows from the CO2 container and exits through the invention's control or release valve.


It is also an object of the present invention to provide a special designed manifold block where the CO2 container(s) are placed on, and which allows the passage of the refrigerant from the CO2 container(s) into the invention's cooling system.


It is an object of the present invention to provide a cooling system containing a heat transfer plate (also referred to as heat exchanger) and liquid and/or gas CO2 distribution through capillary tubes embedded in the said heat exchanger to maximize energy transfer from the liquid and/or gas CO2 to the contents of a vessel which may or may not be insulated, thereby keeping the vessels' contents at a desired temperature.


It is additionally an object of the present invention to provide capillary tube(s) to convey the liquid and/or gas CO2 along the heat transfer plate of the invention's cooling systems. The capillary tube(s) allows the flow of the liquid and/or gas CO2 being released for the purpose of maintaining or reducing the temperature of the containers being cooled by the cooling systems.


It is a further object of the present invention to provide a metering CO2 control releasing system for the CO2 release which enables the controlled release of the liquid and/or gas CO2 inside the invention's cooling systems.


It is a further object of the present invention to provide release valve (also referred to as control valves), as part of the metering CO2 control releasing system, which can be controlled or actuated manually, electromechanically, electronically or thermostatically, to release the liquid and/or CO2 from the CO2 containers into the invention's cooling systems. The invention's control valves are specifically designed to prevent the freezing and clogging and blocking of the capillary(s) tubing by calibrating the control valves to flow the optimal amount of liquid and/or gas CO2. Without the inventions control valves in the invention's cooling systems, the invention's capillary tubes could be clogged or blocked or frozen not allowing the liquid and/or gas CO2 to be properly released. The invention's designed cooling systems are capable of providing a steady and constant flow of liquid and/or gas CO2 to insulated or non-insulated portable units (i.e.: ice chests, coolers, lunch boxes), stationary units (i.e.: refrigerators, freezers), compartments of vehicles (i.e.: trunk or cabinet located in a car or autonomous vehicles), aircrafts, small unmanned aerial vehicles (drone), motorcycles, scooters or bicycles.


It is also an object of the present invention to provide a cooling system with multi-CO2 containers with configuration that comprises check valves. The check valves are used between the container manifold block and the connections joining the CO2 containers. This eliminates liquid and/or gas CO2 from escaping when removing or replacing tanks individually. The compressed CO2 containers are positioned in the invention's specifically designed cooling systems in a vertical upright or upside-down position in order to maintain the CO2 liquid and gas balance within the CO2 container when the liquid/and or gas is expelled from said container.


It has been discovered according to the present invention that when the CO2 container(s) is(are) in an upright position, the invention's control valve has a siphon tube of a suitable length able to reach the bottom of the CO2 container. The siphon tube allows the liquid CO2 to flow from the bottom to the top of CO2 container and then to exit through the invention's control valve.


It has further been discovered according to the present invention that when the CO2 container(s) is(are) in an upside-down position, the liquid goes down because of gravity force and the liquid CO2 flows from the bottom to the top of CO2 container and then exits through the inventions' control valve.


It is an additional object of the present invention to provide a metering CO2 control releasing system which is monitored, controlled and operated electronically using a touch screen or, remotely, using a smartphone application or any other electronic devices. The invention's metering CO2 control releasing system has different configurations according to the type of release valve and to the number of CO2 container(s).


It is also an important object of the present invention to provide cooling systems that also includes an electronic control device powered by battery, solar panel or +12V socket in the car, which allows to monitor and control temperatures, control algorithms, and a metering CO2 control releasing system. These components are attached to, or enclosed in, or can be placed in any kind and any size insulated or non-insulated vessels to minimize heat transfer with the environment.


It is also an object of the present invention to provide a system which contains an electronic control strategy using encrypted data to avoid spoofing, intrusion, interference, meaconing, jamming or data falsification. To encrypt the transmitted data a message authentication code (MAC) method will be used. Because an active control (electronic) is the most accurate, flexible, and easy to operate, it is envisioned that this is the preferred embodiment. Data is transmitted from the active controllers of the inventions' cooling systems via WiFi, Bluetooth and Radio Frequencies to a smartphone or tablet or a server or any kind of other device will be encrypted to avoid spoofing, intrusion, interference, meaconing, jamming or falsifying data.


It is additionally an object of the present invention to provide a cooling system which can be transported, stored and moved to locations which do not have electricity connections, where electrical service has been disrupted (e.g. utility power outage) or which do not have conventional methods for refrigerating, cooling or freezing.


The invention of the cooling systems was envisioned by the inventors working together on delivering the optimum cooling system which results in cooling temperatures utilizing liquid and/or gas CO2 to insulated and not-insulated vessels, containers, compartments, enclosed areas, cooling systems claimed in this invention utilizing any type and size of CO2 containers positioned on, in or near an area where there is a need or desire to reduce or to maintain a specified or required temperature.


Many additional features, apparatus and methods of the present invention are described in the following paragraphs.


The design is specific for the use of coolers and can be also designed for any type of system that is in need of refrigeration. The invention is not required to have any specially made cooler as it is a standalone and can be designed specific.


The present invention includes a specially designed insulated cooler which embeds the invention's cooling system and the electronic control device to monitor and control the temperature.


The present invention includes an additional accessory that can be placed into the cooler to produce ice on a specially designed ice making system in a period of time from 1 to 10 minutes. The mechanism to convey the liquid and/or gas CO2 into the specially designed ice making system may be directly connected to the capillary assembly. The specially designed ice making accessory includes: a) a connection assembly to the principal unit of this invention, b) an ice tray block which is attached to a bottom cold disbursement plate with fasteners, c) a containment tray which holds the water or other liquids where the cold is dispersed into; d) a divider which will be full of water or other liquids. The plate assembly is fastened together by ice tray bottom plate fasteners.


The present invention includes a cooling system for individual beverage containers such as cans/bottles or individual containers, which needs to be cooled or to be maintained at a cooled temperature or frozen. This invention's cooling system has a circular designed casing which, except for the top of the cooling unit, is enclosed allowing for a beverage container to be placed into it. The cooling unit has the invention's control system utilizing the manual, electromechanical, electronic or thermostatic valve depending and according to the type of beverage(s) intended or desired to be cooled.


The present invention also includes a portable cooling system equipped with wheels to be easily transported and which can be easily connected to a refrigerator through a suitable connector designed in collaboration to the refrigerators' makers or a capillary passing through the refrigerator's door gasket in order to deliver CO2 as a coolant to the refrigerator when a power supply outage occurs. The CO2 canister is in the upright position with a siphon tube of a suitable length able to reach the bottom of the CO2 container. The siphon tube allows the liquid CO2 to flow from the bottom to the top of CO2 container and then to exit through the invention's control or release valve. This invention's cooling system is envisioned to be specifically designed to be connected and attached to the refrigerator system to minimize or eliminate the amount of heat transfer from the refrigerator to the external environment.


The present invention additionally includes a system designed to transport goods, which need controlled refrigeration such as medical, pharmaceutical, foods and any other small cooled or frozen items using a Small Unmanned Aerial Vehicle (SUAV, also called “Drone”). This invention's cooling system is envisioned to be specifically designed to be connected and attached to a specific drone according to its mechanical elements.


This disclosure focuses on the system as a whole as well as the electronic control strategy. Because the electronic control system utilizing smartphone communication for monitoring and control and other sensing options is the most accurate, flexible and easy to operate, it is envisioned as the preferred embodiment. Other options such as incorporating a manual, electromechanical or thermostatic CO2 releasing mechanism are envisioned.


The present invention, either standalone or embedded in a specially designed insulated cooler, can be applied to refrigerate, cool or freeze individual bottles, cans or containers, insulated or non-insulated portable units (i.e.: ice chests, coolers, lunch boxes), stationary units (i.e.: refrigerators, freezers), compartments of vehicles (i.e.: trunk or other cabinets of trucks, cars, motorcycles, scooters, bicycles or autonomous vehicles), compartments of aircrafts or small containers transported by drones.
