Definitions

  • the present invention relates to a cooling device and a method of using said device.
  • Self-chilling vessels are based mainly on two different principles, where the first principle uses a closed system separated from the product to be cooled and upon activation initiates an endothermic reaction, which cools the product.
  • US Pat. No. 6,266,879 and US Pat. No. 6,178,753 describe containers based on this principle.
  • the second principle is based on a closed two-chamber system separated from the product to be cooled, where one chamber comprises an evaporation unit and the second chamber comprises an absorbing unit. When a valve is opened between the two chambers a drop-in pressure causes fluid to evaporate from the evaporation chamber and thereby removing heat from the evaporator. A heat removing material in the second chamber absorbs heat of vaporisation.
  • US. Pat. No. 6,829,902 describes a self-cooling can based on the phase-change principle.
  • a drawback related to self-chilling vessels designed according to the prior art is the need of specially designed containers which comprise the cooling elements inside.
  • thermoelectric cooling device from which a wall assembly extends, said wall assembly being configured to retain a beverage in use.
  • thermoelectric device With the solution mentioned above, it is possible to cool a standard beverage can without special measures. However, the need for electricity to supply the thermoelectric device with power dramatically limits the use of such holder.
  • a cooling device uses evaporation of a cooling fluid and has a cooling mantle fitting around the outside of a drinks container made of a material which material holds the cooling fluid.
  • the cooling fluid is fed to the cooling mantle from a cooling fluid reservoir via flow openings in the mantle.
  • the level and timing of the cooling is controlled via a dosing element which dosing element controls the transfer of the cooling fluid from the cooling reservoir to the cooling mantle.
  • the cooling device has hangers which hangers allow the cooling device to be suspended in free air.
  • the cooling device is constituted of many mechanical parts and does not provide an efficient cooling of the drinks container.
  • a drinks container is known.
  • the container is an evaporatively cooled drinks container especially for a motor cyclist, a runner or a mountain biker.
  • the drinks container has a neoprene casing absorbing fluid for cooling and provides insulation for contents with colour change temperature indication.
  • the cooling device does not provide an efficient cooling of the drinks container.
  • a requirement in a competitive world is that such a cooling device need to be user friendly to operate and constituted of simple and easy manufactureable parts.
  • cooling device should only be supplied with a fluid for the cooling which is easy to buy or already used in the household.
  • the cooling device should be applicable outside, in the garden, on the terrace on the beach, etc. Therefore it is another requirement that the cooling device should be able to be operated as a stand-alone equipment e.g. without the need to continuously supply air, e.g. cold air, electricity and/or cooling fluids from outside of the device. Moreover, the cooling device should retain the relative low temperature within the device in e.g. 2 - 4 hours or longer.
  • the outer wall is constituted by a glazed or a sealed window.
  • the user of the cooling device can inspect the interior of the cooling device and see the evaporative liquid level of the fluid reservoir.
  • the window provides for an appealing appearance and touch of the cooling device.
  • the glazed or a sealed window has a heat-absorbing surface such as a coating.
  • the coating further promotes evaporative cooling since more heat is absorbed - due to the coating - in the second passage behind the outer wall, i.e. between the heat insulating wall and the outer wall.
  • the heat-insulating wall has a heat-absorbing surface, e.g. a coating facing the second passage. This further or alternative coating on the heat-insulating wall further promotes evaporative cooling since more heat is absorbed - due to the coating - in the second passage.
  • the product to be cooled comprises a liquid product such as beer or carbonised beer.
  • the fluid absorbing element is manufactured self-supporting such as a structural element constituting a wall. It is hereby possible for the fluid absorbing element - due to its stiffness and stability - to receive and contact the surface of a container or keg containing beer. Due to the contact between the container or keg and the fluid absorbing element, which evaporates an evaporation fluid, the evaporative cooling is further promoted.
  • the fluid reservoir contains the above discussed evaporation fluid preferably water or ice, a combination of water and ice, water with a content of an alcoholic liquid, methanol, ethanol or other volatile liquids or any mixture of the aforementioned liquids.
  • the fluid reservoir is placed in the base portion and/or on top of the cooling device.
  • the outer container is an upwardly open container, and the cooling device further is provided with a cover on its top.
  • the cover seals off the upper open end of the outer container and includes inner and downwardly protruding separation flanges which flanges separate the first passage from the second passage and thereby allow air from the environment to be guided into the first passage and further allow air to pass out from the second passage to the environment.
  • the method further has any of the features of the cooling device as discussed above.
  • the product to be cooled or to be kept cooled is arranged proximate to or in direct contact with the fluid-absorbing element.
  • the product to be cooled or to be kept cooled is arranged in the one or more containers and the container or containers are in contact with the fluid-absorbing element.
  • the cooling device is used for the cooling of food and/or beverage containers or for air-condition systems or refrigerators.
  • This object is achieved with a cooling device in accordance with claim 1 and a method.
  • the use of a fluid reservoir makes it possible to provide for continuous cooling by simple measures.
  • the device can be produced at a low cost and requires no hazardous substances in order to operate, which makes it environmentally friendly and suitable for disposable systems.
  • a gas flow is arranged in the atmosphere on said second side of the fluid-absorbing element, such as a wick or blotting paper, in order to enhance evaporation of fluid from the fluid-absorbing element.
  • the fluid-absorbing element such as a wick or blotting paper
  • the cooling device can also comprise a heat-absorbing surface that at least partially covers the fluid-absorbing element in such manner that there is a clearance forming a passage between the fluid-absorbing element and the heat-absorbing surface, wherein said gas flow is created in said passage by means of convection as said heat-absorbing surface is heated.
  • a heat-absorbing surface that at least partially covers the fluid-absorbing element in such manner that there is a clearance forming a passage between the fluid-absorbing element and the heat-absorbing surface, wherein said gas flow is created in said passage by means of convection as said heat-absorbing surface is heated.
  • said passage may be closed at one end and a thermal insulator be arranged between the heat-absorbing surface and the fluid-absorbing element, dividing said passage into an essentially U-shaped passage. This isolates the fluid-absorbing element from heat generated by the heat-absorbing surface while providing an enhanced gas flow.
  • the gas flow may also be enhanced with a fan, preferably powered by electricity.
  • the product to be cooled is a liquid product, preferably a beverage, e.g. beer or a carbonised beer.
  • the product to be cooled may be arranged in direct contact with the inner wall or arranged in a separate container, the latter being adapted for contact with the inner wall.
  • a conceptual drawing of a first embodiment of a cooling device 10 comprises an inner wall 12 configured to enclose a product 14.
  • Said inner wall 12 comprises a fluid-absorbing element, such as a wick or blotting paper 16 which is exposed to a gas flow, generally depicted by the arrow at 18.
  • the fluid-absorbing element will be referred to as a wick.
  • the wick 16 is in contact with a liquid reservoir 20 which liquid reservoir 20 continuously supplies the wick with liquid.
  • the gas flow 18 stimulates evaporation of the liquid to occur and thereby removes heat from the inner wall 12, which consequently cools the product inside the inner wall 12.
  • the inner wall 12 is preferably made of a noncorrosive material with adequate heat transportation properties, such as aluminium, stainless steel or plastics.
  • the walls 15 not covered by the wick 16 generally comprises insulation preventing heat to be transported through the walls 15.
  • the cooling capacity is derivable from elementary thermodynamics, which will not be further discussed here.
  • the gas flow described in the first embodiment is enhanced by the use of a fan 17 (showed in phantom in Fig. 1 ).
  • a higher flow of gas will increase the rate of fluid evaporation from the wick and thereby increase the cooling rate.
  • the fan is powered by electricity, preferably solar energy, but it could also be powered by an external wind energy source or other means.
  • a cooling device 10' according to a third embodiment of the present invention is shown. Compared to the first embodiment similar parts have been given the same reference numbers.
  • the inner wall 12' is configured to enclose a beverage can 14' of standard type, and is surrounded by an outer wall 22, positioned in such a way that a passage 24 is created between the inner wall 12' and the outer wall 22.
  • the fluid-absorbing wick 16' positioned in an abutting relationship to the side of the inner wall 12' facing the outer wall 22, is made of sponge material, foam material, textile fibre or regenerated cellulose.
  • the distance between the outer wall 22 and inner wall 12' is 3-4 mm in order to prevent the evaporated fluid bridging the gap between the outer wall 22 and the inner wall 12' during use, while at the same time obtaining an increased airflow.
  • the outer wall 22 is designed to comprise a heat-absorbing portion 26 causing gas to heat up in the passage 24. This increase in temperature decreases the density of the gas and thereby catalyses convection to occur. Consequently, warm air leaves the cooling device 10' as illustrated by the arrow 19.
  • the liquid reservoir 20' is positioned at a base portion 28 of the device.
  • the liquid reservoir 20' contains water 21 or ice, e.g. cubed and/or crunched ice, however, different kind of liquids could be used, for example refrigerants having a lower evaporation temperature and thereby enhancing the cooling procedure.
  • Water is, however, a preferred liquid, since it is non-toxic and relatively easy to obtain.
  • ice is provided which ice during use of the cooling device 10' melts to water.
  • the liquid is water with a content of alcoholic, e.g. 5 %, 10 % etc.
  • the liquid is methanol, ethanol or other volatile liquids.
  • the liquid may also be any mixture of the aforementioned liquids.

  • the heat-absorbing portion 26' of the outer wall 22' is coloured black or is provided with a black coloured surface, e.g. it is coloured tarnish black in order to increase heat absorption of the heat-absorbing portion 26'.
  • the heat-absorbing portion 26' of the cooling device 10" is intended to be subjected to heat, preferably direct sunlight, which naturally heats up the heat-absorbing portion 26' since the black surface does not reflect but absorbs the heat from the sun.
  • the sun typically heats with 1000 watt per square meter and consequently warm air leaves the cooling device 10" as illustrated by the arrow 19' and relative cold, atmospheric air 18' is at the same time forced into the cooling device 10" through the passage 23.
  • the water reservoir 20" is arranged on top the device 10".
  • the water reservoir 20" may be placed in the base portion 28' of the device 10", or two water reservoirs could be combined so that the wick 16" fluidly connects an upper reservoir with a reservoir 20" arranged in the base portion 28'.
  • the passage 24' is closed at its lower end and a thermal insulator is arranged as an intermediate wall 32 between the heat-absorbing surface 26' of the outer wall 22' and the wick 16", dividing said passage 24' into an essentially U-shaped passage 30.
  • the intermediate wall 32 is accurately positioned by means of extensions 30, connecting the lower portion of the intermediate wall 32 with a bottom of the device 10", while leaving channels through which air may flow freely.
