Definitions

  • the invention relates to an apparatus for cooling foods, in particular water-based drinks, which is described in the preamble of claim 1 .
  • a cold accumulator is provided in the form of an ice bank which is cooled via a coolant by the cold side of a Peltier plate module.
  • the drink to be cooled is passed round or through the ice bank.
  • the thermal conductivity of the ice water and therefore the heat transfer properties of the ice bank can be improved by distributing a good conductor, such as, for example copper wool or copper pieces, in its volume.
  • the cooling of foods and drinks by ice is current practice, but has critical disadvantages.
  • a main disadvantage is the low thermal conductivity of ice.
  • EP 914 399 B1 discloses a composite material in which pressed expanded graphite is impregnated with a phase change material.
  • the graphite acts as heat conductor which in addition is able to take up the most varied phase change materials.
  • phase change material use can be made of paraffin, but preferably likewise water/ice.
  • Peltier elements suggest themselves, in which, by applying an electric field to two different electric conductors, one side heats up and the other cools down.
  • U.S. Pat. No. 5,544,489 discloses in this respect an improvement in capacity by utilization of the melting enthalpy of the water to be cooled. For this, on the cold side of the Peltier element, ice is generated within a water reservoir, as a result of which the energy density of the cold accumulator is markedly increased.
  • both said apparatuses are opposed by the expected high microbial loading due to stagnant water in a reservoir with respect to approval under drinking water law.
  • EP 0 777 090 provides an aid in this respect with the essential difference from U.S. Pat. No. 5,544,489 that the drinking water to be cooled is passed through the ice-cooled reservoir in a pipe coil and direct contact is therefore avoided.
  • a problem in this regard of the spatial dimensions of such an apparatus is that the space filled by ice is no longer available for the drinking water coil.
  • a fundamental problem of all known continuous-flow Peltier-based chillers is the low efficiency of Peltier elements which is predominantly determined by the temperature difference between the cold and warm sides.
  • the warm side by use of corresponding cooling bodies and aeration fans, is problem-free in principle and technically solved
  • the cold side is a problem which has not yet been solved to date.
  • Owing to the low specific thermal conductivity of the cold accumulator medium used [ ⁇ water approximately 0.57 W/(mK), ⁇ ice approximately 2.2 W/(mK)], there is an increase in the temperature difference and thus an impairment of the efficiency.
  • the object of the present invention is to provide an apparatus for cooling foods, in particular water-based drinks, which is simple and inexpensive to produce and has a high cooling capacity.
  • an apparatus for cooling foods in particular water-based drinks
  • a cold accumulator used according to the invention and made of expanded graphite and a phase change material which passes through its solid-liquid phase change at or above 273 K, that is the freezing temperature of water, preferably a few ° C.
  • a very effective cold accumulator which firstly, as a result of the graphite, has a high thermal conductivity, and thereby ensures relatively rapid shock-like cooling, and which secondly comprises a phase change material which, even without complicated control technology, does not involve the risk that water-based drinks freeze and form an ice block.
  • the size of the cold accumulator required for good performance is decreased, and secondly the space and costs of comprehensive control are saved.
  • a Peltier element is provided which further has the advantage that the liquid flowing through the line can be heated for disinfection by reversing the polarity of the voltage supply of the Peltier element.
  • Peltier elements are very cheap. The comparatively low thermal efficiencies of a Peltier element are of less importance owing to the very effective storage material having expanded graphite, in particular when there is the possibility of being able to “charge” the cold accumulator in idle times of the apparatus, for example during the night.
  • conventional refrigerator technology can also be used, for example the absorber or compressor technique for “charging” the cold accumulator.
  • conventional refrigerator technology can also be used, for example the absorber or compressor technique for “charging” the cold accumulator.
  • the cold accumulator into a conventional refrigerator and there, either for equipping the refrigerator for active and effective shock cooling, for example to use it in the area of the freezer compartment, or to use it for dispensing a drink, for example water, from a central water supply, in or on the refrigerator, in the course of a shock-like continuous-flow cooling.
  • the invention may also be used advantageously wherever a high cooling capacity with periodic load or fluctuating cooling power requirement must be provided inexpensively with small spatial dimensions.
  • a material as cold accumulator medium which passes through a phase change at, or a few ° C. above, the freezing point of water, for which in principle salt hydrates, eutectic mixtures and also paraffins are suitable.
  • the cold accumulator medium is admixed with expanded graphite, as a result of which the thermal conductivity can be increased by up to a factor of 150.
  • the invention is in addition suitable for construction of a cooling container, wherein the cold accumulator can be integrated into an insulated wall of the cooling container, or into the interior, wherein the interior can also be completely filled by the cold accumulator.
  • the apparatus according to the invention for example inexpensively available commercially conventional refrigerators can be refitted in this manner.
  • the invention can, for example, also be used as a shock-cooling unit for dispensing drinking water into a cooling container.
  • the invention is also particularly suitable for dispensing units, wherein, in the interior of a housing, a drink source, for example a beer keg, can be received and the cold accumulator is active both in the interior and in the dispense line.

  • FIG. 1 shows a device according to the invention for chilling foods having a cylindrical container 1 which has an introduced line in the form of a pipe coil 8 through which passes a water-based liquid to be cooled from an inlet 5 to an outlet 4 .
  • the liquid to be cooled can be either the drink to be cooled, preferably water with or without gas admixture (carbon dioxide and/or oxygen) which originates from a water source, preferably the central local water supply.
  • the liquid can be a coolant, which is, however, preferably likewise water and originates from the central water supply, but serves for cooling foods or drinks at another point.
  • the container 1 is filled by a cold accumulator 6 which comprises a composite material made of expanded graphite and also a material which passes through a phase change at or above 273 K, the phase change preferably being a few ° C. (up to 10° C., preferably 3° to 5° C.) above the freezing point of water.
  • a cold accumulator 6 which comprises a composite material made of expanded graphite and also a material which passes through a phase change at or above 273 K, the phase change preferably being a few ° C. (up to 10° C., preferably 3° to 5° C.) above the freezing point of water.
  • Suitable phase change materials are preferably salts and also paraffins known for their phase change properties.
  • the graphite is present as free-flowing granules and is impregnated with the phase change material.
  • the heat taken up from the liquid in the pipe coil 8 is taken off from the cold accumulator 6 again by a suitable unit.
  • the unit in the example shown is a Peltier element 2 which is in intimate contact with the cold accumulator 6 by its cold side.
  • the hot side of the Peltier element 2 is provided with an apparatus 3 for transporting away the heat.
  • the apparatus 3 can be any suitable apparatus and is in particular a fan as is customarily used with Peltier elements.
  • measures can be taken to reverse the polarity of the Peltier element 2 so that if appropriate the liquid flowing through the line 8 can be heated for disinfection.
  • the point of the container 1 at which the Peltier element 2 is mounted is made of a readily-conducting material, in particular a metallic material.
  • Peltier elements can be provided.

  • a cold accumulator 6 is accommodated which this time consists of plate-type, expanded graphite which was impregnated with the same phase change material which has already been described with reference to FIG. 1 .
  • the cold accumulator has a layer structure, with plates of the graphite material alternating with a layer-type arrangement 7 of suitably shaped and laid lines which, however, again extend from the container 1 by the water outlet 4 and the water inlet 5 .
  • the layer-type arrangement 7 can contain, for example, a meander-like line geometry 9 of FIG. 4 or a spiral-type line geometry 10 of FIG. 5 .
  • Each line layer 7 is connected by inlet and outlet in a manner which is not shown to the adjacent line layers, with the first and last line layers being connected to the water outlet 4 and the water inlet 5 , respectively.
  • the line layers can either be laid as pipes, or in the shape of profiled plates, wherein preferably two plates are provided in a mirror image fashion with corresponding embossings of the size of the half cross section of the line, and the plates are subsequently laid one upon the other and are fastened to one another, so that the embossings supplement each other to give continuous channels which are closed on the periphery side.
  • the profile plates consist of readily heat-conducting material, for example metal.
  • the lines 8 , 9 or 10 preferably have a diameter between 3 and 11 mm, in particular 4-10 mm, since, with this diameter, in combination with a water pressure as is supplied on average by a water pipe grid (1.5-4.5 bar) which, if appropriate, can be set by a pump or a pressure-reducing valve to a constant insignificantly varying pressure ( ⁇ 0.5 bar), a strong flow counteracting microbial infestation forms.
  • the layer-like arrangement according to FIGS. 3 to 5 is preferably produced by compressing the line layers having the graphite plates, which leads to a particularly intimate, heat-transferring contact between the layers.

  • the cold accumulator 6 can also be accommodated anywhere in a wall 15 (including base and upper cover or door 14 ) or in an intermediate base or the like.
