Definitions

  • the present invention is directed to a cooling device for cooling a storage space of a cooling container and a respective cooling container.
  • a cooling container comprises a thermally isolated space, in which the goods can be kept during transport. Thereby, the temperature within the cooling container can be maintained below a temperature threshold merely due to the thermal isolation from the environment.
  • passive methods for maintaining a low temperature are not sufficient, e. g. depending on the ambient temperature and/or for products that are particularly heat-sensitive.
  • a temperature cannot be maintained below a threshold over a long period of time.
  • active means for cooling within cooling containers can comprise, for example, electrically and/or mechanically driven cooling apparatuses.
  • cooling apparatuses consume energy, which may not be available in particular during transport.
  • coolants such as solid carbon dioxide are used for (active) cooling.
  • solid carbon dioxide By introducing solid carbon dioxide into a thermally isolated cooling container, a low temperature within the cooling container can be maintained over a longer period of time.
  • using solid carbon dioxide is often energetically inefficient. Cooling over a sufficiently long period of time may be achieved only by such a high initial cooling power that the temperature in the cooling container might be reduced more than necessary and/or desired. Due to such an unnecessary cooling energy is wasted.
  • the goods that are cooled can be damaged if the temperature falls below a lower threshold. Further, for some applications even with carbon dioxide a sufficient cooling over a sufficiently long period of time cannot be achieved according to prior art approaches, such as shown in US2196310 , US3906744 , DE19840262 and US1897095 .
  • a cooling device is provided as defined in claim 1.
  • cooling container may be understood broadly in this context. Any device having a storage space for receiving goods that are supposed to be cooled can be considered a cooling container.
  • the cooling container can be suitable for cooling and transporting food products.
  • the storage space is situated in the interior of the cooling container.
  • the cooling container preferably comprises container walls that confine the storage space. Preferably, the cooling walls are thermally isolated.
  • the cooling device can be arranged within the storage space or adjacent to the storage space.
  • the cooling device is in particular capable of cooling the storage space.
  • the cooling device may be attached fixedly to the cooling container or may be attached removably to the cooling container.
  • the cooling device is particularly suitable for receiving a coolant.
  • the coolant can be, for example, solid carbon dioxide or carbon dioxide snow.
  • the coolant can cool the storage space of the cooling container.
  • the amount of coolant used may be chosen depending on the size of the storage space, the amount of goods placed therein, a temperature of the environment, a threshold under which the temperature within the storage space is to be maintained and/or a desired period of time over which the temperature is supposed to be maintained below the threshold.
  • the coolant space is confined at least partly by the housing walls of the cooling device.
  • the coolant space is confined entirely by the housing walls of the cooling device.
  • the housing walls preferably comprise an opening, via which the coolant can be introduced into the coolant space and which can be closed, for example, by a cover or by a hatch.
  • the coolant space is confined by the housing walls except for one side of the coolant space. This may be the case, for example, if the housing walls constitute a trough or a bucket.
  • the cooling device is preferably attached to the cooling container such that the open side of the coolant space is closed by a container wall.
  • the housing walls are preferably divided into the main heat transfer zone and the thermal isolation zone. Alternatively, there may be further zones with a different function.
  • a zone is to be understood as a section of the housing walls that is intended and equipped for a certain purpose. Therefore, the housing walls may have different properties in the different zones, in particular different heat transfer coefficients.
  • a zone may comprise a single area of the housing walls. Such a zone is a connected, that is, contiguous, area of the housing walls. Also, a zone may comprise multiple areas of the housing walls that are not connected, that is, not contiguous. Areas of the housing walls with the same properties that are intended for the same purpose constitute a single zone, regardless if it is one single connected area or multiple areas that are not connected.
  • the thermal isolation zone ideally does not allow any heat transfer between the coolant space of the cooling device and the storage space of the cooling container. However, for practical reasons, a minor heat transfer may be allowed. In particular, it might be unreasonable to provide a thermal isolation that is capable of suppressing any measurable heat transfer. Such a thermal isolation might be large, heavy and/or expensive. Hence, it is preferred that the thermal isolation zone suppresses the heat transfer between the coolant space of the cooling device and the storage space of the cooling container as far as this is reasonably achievable. Therefore, the first heat transfer coefficient of the thermal isolation zone may be as low as reasonably achievable.
  • the housing walls of the cooling device may comprise a thermally isolating material. The thermally isolating material may be added to the housing walls as a thermal isolation layer. Alternatively, the housing walls can be formed by a thermally isolating material in the thermal isolation zone.
  • the main heat transfer zone is supposed to allow heat transfer between a coolant provided within the coolant space of the cooling device and an outside of the cooling device, e. g. the storage space of the cooling container. Therefore, the second heat transfer coefficient of the main heat transfer zone may be as high as reasonably achievable or as being appropriate for the desired use of the cooling device, e. g. depending on the temperature threshold(s), the necessary duration of cooling etc..
  • the housing walls of the cooling device can be made with a plastic and/or a metal.
  • the cooling effect that is achievable with the coolant has two major parameters: the cooling power and the total cooling energy.
  • the cooling power is a measure for a momentarily achievable cooling effect. The higher the cooling power of the coolant is, the more can a temperature of the storage space be affected. If a particularly low temperature is desired for the storage space, for example to provide cooling for frozen food products, a particularly high cooling power is required.
  • the cooling energy is the cooling power integrated over time, in particular over a period of time. In particular, this period of time covers the whole time over which the coolant can provide a cooling effect. The longer a low temperature is supposed to be maintained and/or the lower the temperature is supposed to be maintained, the higher the cooling energy has to be.
  • the cooling power depends highly on the surface of the coolant, via which heat can be transferred form the storage space of the cooling container to the coolant.
  • the cooling energy depends highly on the total volume of the coolant that is provided. That is, a high volume of a coolant with a small surface can provide a low cooling effect over a long time, while a small volume of a coolant with a large surface can provide a high cooling effect over a short time.
  • the ratio of volume to surface can only be chosen within geometrical limits. In particular, no geometrical object has a larger surface to volume ratio than a sphere. That is, by merely placing a coolant into a cooling container, the ratio between the cooling energy and the cooling power cannot be chosen limitless.
  • the cooling power therefore cannot be restricted to a particularly low value merely by providing the coolant in a particular shape.
  • the cooling power will always be at least as high as for a spherical coolant.
  • the cooling power is not constant over time.
  • the higher the cooling power the higher the heat transfer of the coolant and, hence, the faster the coolant evaporates and/or melts.
  • a high cooling power coincides with a high coolant consumption.
  • the cooling power is high and constant over a (long) period of time. That way, the temperature in the storage space of the cooling container can be maintained at the same or at a similar value over a long period of time.
  • a high cooling power after a particularly long period of time can only be achieved by initially providing a particularly high amount of coolant. Due to the described limited surface-to-volume-ratio and due to the consumption of coolant, initially the cooling power must thereby be higher than required. Hence, energy would be wasted by merely placing the coolant into the cooling container.
  • the high initial cooling power may reduce the temperature within the storage space below a desired lower threshold, potentially causing damage to the goods stored therein.
  • cooling can be achieved which is particularly close to the ideal situation with a high cooling efficiency considering the consumption (evaporation, melting) of coolant. Therefore, the surface via which heat can be transferred is reduced by the thermal isolation zone.
  • the coolant As the coolant is provided within the coolant space, heat between the coolant and the storage space of the cooling container can be transferred mainly via the main heat transfer zone and in particular not or to a negligible degree via the thermal isolation zone.
  • a ratio between the surface for heat transfer and the volume of the coolant can be reduced in particular beyond what is achievable when merely placing a coolant into a cooling container. This may be particularly achieved if the thermal isolation zone and the main heat transfer zone are sized accordingly.
  • the cooling device can provide a cooling effect with a cooling power that drops particularly slowly over time.
  • a particularly high cooling power can be achieved even after a particularly long period of time. Therefore, no high initial cooling power is required so the consumption of coolant is reduced compared to prior art approaches.
  • a particular constant cooling power can prevent damage from the goods stored within the storage space as the temperature can be prevented from dropping too low.
  • the eutectic material can contribute to the described advantages.
  • the eutectic material is a material which is particularly capable of storing cooling energy. Hence, the eutectic material can incorporate cooling energy, store the cooling energy and emit the cooling energy later.
  • the eutectic material is provided within the cooling space.
  • the eutectic material is enclosed within a casing such that the eutectic material can be brought into contact with the coolant only thermally, not physically.
  • the coolant and the eutectic material can, hence, exchange heat, but do not get mixed. Despite such a casing, the eutectic material is considered being arranged within the coolant space.
  • the eutectic material is enclosed in the cooling device and/or in the casing such that the eutectic material cannot leak from the cooling device and cannot come into contact with the goods stored in the storage space. This is particularly advantageous if food products are stored in the storage space and/or if the eutectic material can be harmful to health. It is, however, particularly preferred to choose an eutectic material is not harmful to health
  • the eutectic material can be cooled in particular by the initial cooling power of the coolant. It is assumed that the coolant is placed into the cooling device at the beginning of a cooling process. The eutectic material thereby is assumed to have a relatively high initial temperature, e. g. having a temperature in the range of the ambient temperature outside the cooling container. In that case the coolant can cool the storage space of the cooling container as well as reduce the temperature of the eutectic material. Hence, the eutectic material can incorporate the cooling energy emitted by the coolant in particular during an initial phase of the cooling. In particular in this phase, the initial cooling power may be higher than required as discussed above. This excessively high initial cooling power could reduce the efficiency of coolant consumption.
  • the eutectic material can contribute to saving energy by storing the cooling energy in the initial phase of the cooling.
  • the energy liberated by the consumption of the coolant is not wasted i. e. resulting in an unnecessary strong cooling of the cooling container but stored by the eutectic material instead.
  • the cooling energy stored within the eutectic material may be released such that the coolant and/or the interior of the cooling container are cooled.
  • the cooling power provided by the cooling device can be increased in particular in the later phase of the cooling. In the later phase of the cooling the cooling power of the coolant may be reduced significantly due to consumption of the coolant.
  • the described advantages can be achieved in particular if the thermal isolation zone has covers larger surface area of the housing walls than the main heat transfer zone.
  • the thermal isolation zone has a thermal isolation surface area and the main heat transfer zone has a main heat transfer surface area, wherein the thermal isolation surface area is at least twice as large as the main heat transfer surface area.
  • the thermal isolation surface area is the surface area of the housing walls covered by the thermal isolation zone.
  • the main heat transfer surface area is the surface area of the housing walls covered by the main heat transfer zone.
  • the cooling device housing walls further comprise an auxiliary heat transfer zone, in which the eutectic material adjoins the housing walls so that the eutectic material can cause a cooling of the storage space of the cooling container via the auxiliary heat transfer zone.
  • the housing walls are preferably divided into three zones: the main heat transfer zone, the thermal isolation zone and the auxiliary heat transfer zone.
  • the thermal isolation zone preferably no or only an acceptable amount of heat can be transferred between the coolant and the storage space of the cooling container.
  • the main heat transfer zone heat can be transferred between the coolant and the storage space. This is particularly relevant in an initial phase of the cooling. Over time, the cooling power provided by the coolant decreases so that less heat can be transferred via the main heat transfer zone.
  • the eutectic material can provide cooling also in a late phase of the cooling. That is, in particular in the late phase of the cooling, the eutectic material is relevant for providing cooling üpwer.
  • Heat can be transferred between the storage space of the cooling container and the eutectic material via the auxiliary heat transfer zone. That is, the heat transferred between the storage space of the cooling container mainly takes place via the main heat transfer zone, wherein heat is exchanged with the coolant. In addition, heat can be exchanged between the storage space and the eutectic material via the auxiliary heat transfer zone.
  • the cooling provided by the eutectic material can be considered an indirect cooling as cooling energy provided by the coolant is stored and subsequently emitted by the eutectic material. Also, the cooling by the eutectic material is an additional cooling that enhances the effect of the cooling provided by the coolant.
  • the heat transfer zone for transferring heat between the eutectic material and the storage space is referred to as the auxiliary heat transfer zone.
  • the described advantages can be achieved in particular if the main heat transfer zone is larger than the auxiliary heat transfer zone.
  • the auxiliary heat transfer zone has an auxiliary heat transfer surface area, wherein the main heat transfer surface area is at least twice as large as the auxiliary heat transfer surface area.
  • the auxiliary heat transfer surface area is the surface area of the housing walls covered by the auxiliary heat transfer zone.
  • the main heat transfer surface area is larger than the auxiliary heat transfer surface area by a factor of at least three, in particular of at least four.
  • the housing walls comprise a first trough, which is thermally isolated in the thermal isolation zone, and a second trough, which is smaller than the first trough, and which is inserted into the first trough, thereby confining the eutectic material between the second trough and the first trough.
  • a trough in the definition applied here is a casing which is closed at all but one sides, in particular being closed at the bottom and on all lateral sides, but being open at the top.
  • bottom and top are used to describe the trough if provided in a usual orientation.
  • the troughs can be described particularly well if a usual orientation is assumed. In the following description, thus, such an orientation will be assumed.
  • the troughs are provided in this orientation within the cooling container while the latter is in the orientation in which it is ordinarily stored and transported. However, this does not mean that the troughs may only be provided in this particular orientation. It is also possible to provide the troughs in any other orientation within the cooling container.

It is preferred that in the thermal isolation zone and in the auxiliary heat transfer zone the housing walls of the cooling device are formed by the first trough only and not by the second trough.
  • the second trough can be inserted into the first trough in such a way that the eutectic material is enclosed between the thermally isolated bottom of the first trough, the lateral sides of the first trough and the bottom of the second trough.
