Description

Die Erfindung betrifft einen Behälter mit mindestens einem Kühlmodul, das ein Kühlmittelreservoir aufweist.The invention relates to a container having at least one cooling module, which has a coolant reservoir.

Bekannt sind Kalthaltungseinrichtungen zur Lagerung und zum Transport von Kühlgut, in denen verflüssigte Gase als Kühlmittel eingesetzt werden. Dabei ist es üblich das flüssige Gas am oberen Ende eines zu kühlenden Behälters in ein schubladenähnliches Reservoir einzubringen. Bekanntermaßen wird dabei Kälte über die Trennwand des Reservoirs an das Kühlgut im Kühlraum abgegeben, sowie verdampftes Kältemittel zur weiteren Produktkühlung in den Kühlraum geleitet. Bei dieser Anordnung treten jedoch Nachteile auf: Sie ist nicht gut geeignet für sehr kälteempfindliches Kühlgut wie beispielsweise frischen Salat, der im Plusbereich von Celsiusgraden gekühlt werden soll. Zur Abmilderung der Kälteeinwirkung ist die Verwendung von Kunststoffplatten bekannt, deren Pufferwirkung allerdings nicht für alle Anwendungen ausreicht. Der Begriff Kühlen wird hierbei und im Folgenden für Abkühlen und Kalthalten im Bereich von Plusgraden und von Minusgraden verwendet. Ein Behälter gemäß dem Oberbegriff von Anspruch 1 ist aus US 1 897 095 bekannt.Kalthaltungseinrichtungen are known for storage and transport of refrigerated goods, in which liquefied gases are used as a coolant. It is customary to introduce the liquid gas at the upper end of a container to be cooled in a drawer-like reservoir. It is known that cold is discharged through the partition wall of the reservoir to the refrigerated goods in the refrigerator, and passed evaporated refrigerant for further product cooling in the refrigerator. In this arrangement, however, there are disadvantages: It is not well suited for very cold-sensitive refrigerated goods such as fresh salad, which should be cooled in the plus range of Celsius degrees. To mitigate the effects of cold, the use of plastic plates is known, the buffer effect, however, is not sufficient for all applications. The term cooling is used here and hereinafter for cooling and cold holding in the range of plus degrees and minus degrees. A container according to the preamble of claim 1 is made US Pat. No. 1,897,095 known.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur produktschonenden und an die Bedürfnisse des Kühlguts angepaßten Kühlung zur Verfügung zu stellen, die unabhängig von einer Energieversorgung betrieben werden kann, und daher zum Transport und zur Lagerung von Kühlgut besonders geeignet ist.The present invention has for its object to provide a device for gentle to the product and adapted to the needs of the refrigerated cooling available, which can be operated independently of a power supply, and is therefore particularly suitable for the transport and storage of refrigerated goods.

Die gestellte Aufgabe wird dadurch gelöst, dass an das Kühlmittelreservoir auf der einem Kühlgut zugewandten Seite angrenzend ein vom Kühlmittelreservoir getrennter Hohlraum vorgesehen ist, der eine eutektische Kühlsole enthält. Die eutektische Kühlsole hat die Eigenschaft Kälte aufnehmen zu können und bei der Weitergabe der Kälte an das Kühlgut bzw. bei der Aufnahme von Wärme von dem Kühlgut eine Pufferfunktion zu übernehmen. Die Pufferwirkung rührt von der Eigenschaft der Kühlsole her bei Unterschreitung einer bestimmten Temperatur in den festen Zustand überzugehen und somit Kälte zu speichern, und zwar in einem Umfang der mindestens der Schmelzwärme des entstandenen Feststoffs entspricht.The stated object is achieved in that a cavity separate from the coolant reservoir, which contains a eutectic cooling brine, is provided adjacent to the coolant reservoir on the side facing a refrigerated goods side. The eutectic cooling brine has the property of being able to absorb cold and to take over a buffering function when transferring the cold to the refrigerated goods or when absorbing heat from the refrigerated goods. The buffer effect is due to the property of the cooling brine forth in falling below a certain temperature in the solid state and thus to store cold, in an amount equal to at least the heat of fusion of the resulting solid.

Das Kühlgut kann z. B. im Plusbereich von Celsiusgraden auf einer bestimmten Temperatur kühl zu haltende Frischware sein. Es besteht aber auch zusätzlich die Möglichkeit eine Produktabkühlung der Frischware durchzuführen. Ebenfalls ist es möglich die Erfindung zum Transport von Tiefkühlware einzusetzen. Die Eignung der Erfindung für die Verwendung bei Frisch- oder Tiefkühlware ergibt sich aus der Möglichkeit sowohl die Menge an Kühlmittel im Kühlmittelreservoir, als auch die Menge an eutektischer Kühlsole im Hohlraum zu variieren. Bei einer größeren Menge Kühlmittel im Kühlmittelreservoir steht durch das Kühlmodul eine größere Kälteleistung zur Kühlung des Inhalts des Behälters zur Verfügung. Je mehr eutektische Kühlsole zur Verfügung steht, desto größer ist die Pufferkapazität.The refrigerated goods can z. B. in the plus range of degrees Celsius at a certain temperature to be kept cool fresh produce. But it is also possible to carry out a product cooling of the fresh product. It is also possible to use the invention for the transport of frozen food. The suitability of the invention for use in fresh or frozen food results from the ability to vary both the amount of coolant in the coolant reservoir, as well as the amount of eutectic cooling brine in the cavity. With a larger amount of coolant in the coolant reservoir is through the cooling module, a larger cooling capacity for cooling the contents of the container available. The more eutectic brine available, the greater the buffering capacity.

Der Hohlraum ist durch eine Platte vom Kühlmittelreservoir abgetrennt die Platte ist aus Stahl oder Edelstahl gefertigt. Es ist auch vorteilhaft, das gesamte Kühlmodul aus den genannten Metallen zu fertigen.The cavity is separated by a plate from the coolant reservoir the plate is made of steel or stainless steel. It is also advantageous to manufacture the entire cooling module from said metals.

Bevorzugt weist die Unterseite der Platte vertikale Stege auf. Diese Stege sind dazu gedacht die Wärmeleitung über die Platte zwischen dem Kühlmittelreservoir und der eutektischen Kühlsole weiter zu verbessern. Dazu sind die vertikalen Stege bevorzugt so hoch, dass sie in die eutektische Kühlsole im Hohlraum eintauchen.Preferably, the underside of the plate on vertical webs. These webs are intended to further improve heat conduction across the plate between the coolant reservoir and the eutectic brine. For this purpose, the vertical webs are preferably so high that they dive into the eutectic cooling brine in the cavity.

Zweckmäßigerweise enthält das Kühlmittelreservoir ein flüssiges Gas, insbesondere flüssigen Stickstoff als Kühlmittel. Der Einsatz von flüssigem Stickstoff ermöglicht eine hohe Kälteleistung des Kühlmoduls bei vergleichsweise geringen Abmessungen des Kühlmoduls. Dadurch bleibt vorteilhaft ein großer Teil des Behälters frei für abzukühlendes Gut. Desweiteren ist flüssiger Stickstoff besonders für den Einsatz im Lebensmittelbereich geeignet.Conveniently, the coolant reservoir contains a liquid gas, in particular liquid nitrogen as a coolant. The use of liquid nitrogen allows a high cooling capacity of the cooling module with comparatively small dimensions of the cooling module. As a result, a large part of the container remains advantageously free for good to be cooled. Furthermore, liquid nitrogen is particularly suitable for use in the food industry.

Zweckmäßigerweise ist das Kühlmodul entnehmbar in dem Behälter angebracht. Diese Ausgestaltung bietet Vorteile hinsichtlich einer problemslosen Reinigung des Behälters und hinsichtlich der Wartung des Kühlmoduls.Conveniently, the cooling module is removably mounted in the container. This embodiment offers advantages in terms of a problem-free cleaning of the container and with regard to the maintenance of the cooling module.

Ebenso ist es zweckmäßig, ein Mittel zur Befüllung des Kühlmittelreservoirs mit flüssigem Kühlmittel vorzusehen sowie ein Mittel zur Ableitung von verdampftem Kühlmittel aus dem Kühlmittelreservoir. Die Ableitung des verdampften Kühlmittels ist vorteilhaft aus dem Kühlmittelreservoir heraus und in den das Kühlgut enthaltenden Raum hinein vorgesehen. Dadurch wird ein sehr effektiver Einsatz des Kühlmittels ermöglicht und dessen Fähigkeit Wärme aufzunehmen fast vollständig genutzt.Likewise, it is expedient to provide a means for filling the coolant reservoir with liquid coolant and a means for discharging vaporized coolant from the coolant reservoir. The derivative of the vaporized coolant is advantageously provided out of the coolant reservoir and into the space containing the refrigerated goods. This allows a very effective use of the coolant and its ability to absorb heat almost fully utilized.

Mit besonderem Vorteil steht bei der Ableitung von verdampftem Kühlmittel aus dem Kühlmittelreservoir ein Mittel zur Führung des Kaltgasstroms zur Verfügung. Dieses Mittel ist beispielsweise als Prallteil ausgebildet, an das das aus dem Kühlmittelreservoir ausströmende verdampfte Kühlmittel prallt und dadurch umgeleitet wird. Ein solches Prallteil wird voreilhaft so angebracht, dass z. B. ein Auftreffen des Stroms aus verdampftem Kühlmittel an der Behälterwand verhindert wird. Dadurch kann eine Versprödung der Behälterwand, die beispielsweise aus Kunststoff besteht, vermieden werden.With particular advantage, a means for guiding the cold gas flow is available in the derivation of evaporated coolant from the coolant reservoir. This means is designed, for example, as a baffle part against which the vaporized coolant flowing out of the coolant reservoir bounces and is thereby diverted. Such a baffle is prematurely attached so that z. B. impingement of the flow of vaporized coolant is prevented on the container wall. As a result, embrittlement of the container wall, which consists for example of plastic, can be avoided.

Gemäß einer anderen vorteilhaften Ausgestaltung der Erfindung ist ein Mittel zur Ableitung von verdampftem Kühlmittel direkt aus dem Kühlmittelreservoir heraus in die Umgebung des Behälters vorgesehen. Das verdampfte Kühlmittel kommt dabei nicht mit dem Kühlgut in dem Behälter in Kontakt, sondern wird vorteilhaft gleich vom Kühlmittelreservoir aus nach außen abgeleitet. Es kann einem Sammler für Kühlmitteldampf zugeleitet oder in die Umgebung abgegeben werden. Mit dieser Ausgestaltung ist der Vorteil verbunden, dass die Erfindung in dieser Form auch für sehr empfindliches Kühlgut geeignet ist, das keinen Kontakt mit dem verdampften Kühlmittel verträgt und beispielsweise ein Luftatmosphäre bevorzugt. Als Beispiel für eine solche Ware seien Früchte genannt, die während des Transports in einem erfindungsgemäßen Behälter noch nachreifen sollen.According to another advantageous embodiment of the invention, a means for the discharge of vaporized coolant is provided directly from the coolant reservoir out into the environment of the container. The vaporized coolant does not come into contact with the refrigerated goods in the container, but is advantageously discharged from the coolant reservoir to the outside. It can be fed to a collector for refrigerant vapor or discharged into the environment. This embodiment has the advantage that the invention in this form is also suitable for very sensitive refrigerated goods, which tolerates no contact with the vaporized coolant and, for example, an air atmosphere preferred. As an example of such a commodity fruits are mentioned, which should ripen during transport in a container according to the invention.

Die Erfindung bietet weitere Vorteile:

  • Mit der Erfindung wird eine besonders produktschonende und an die Bedürfnisse des Kühlguts angepaßte Kühleinrichtung zur Verfügung gestellt, die sehr gut zur Temperaturhaltung von Lebensmitteln geeignet ist. Die gute Dosierbarkeit des eingesetzten Kühlmittels (z. B. Flüssiggas, insbesondere flüssiger Stickstoff) und die Kältespeicherfähigkeit der eutektischen Kühlsole trägt maßgeblich dazu bei, daß der Kühlmitteleinsatz sinnvoll minimiert werden kann. Darüber hinaus ermöglicht der erfindungsgemäße Behälter auch aufgrund der großen Oberfläche des Kühlmoduls, die dem Kühlgut zugewandt ist, einen sehr guten Wärmeübergang und eine gleichmäßige Temperaturverteilung, sowie eine effiziente Nutzung der bereitgestellten Kälteleistung.
The invention offers further advantages:
  • With the invention, a particularly gentle to the product and adapted to the needs of the refrigerated cooling device is provided, which is very well suited for maintaining the temperature of food. The good meterability of the coolant used (eg liquid gas, in particular liquid nitrogen) and the cold storage capacity of the eutectic cooling brine contributes significantly to the fact that the coolant is used can be minimized meaningful. In addition, the container according to the invention also allows due to the large surface of the cooling module, which faces the refrigerated goods, a very good heat transfer and a uniform temperature distribution, as well as an efficient use of the provided cooling capacity.

Durch die eutektische Kühlsole im Hohlraum wird also eine Pufferwirkung erzielt, die zum einen den Verbrauch an flüssigem Kühlmittel, z. B. flüssigem Stockstoff, senkt und zum anderen Frischware im Plusbereich von Celsiusgraden vor Anfrierungen schützt.By the eutectic cooling brine in the cavity so a buffer effect is achieved, on the one hand the consumption of liquid coolant, for. As liquid stock, lowers and protects the other fresh produce in the plus range of degrees Celsius degrees from frostbite.

Die erfindungsgemäße Vorrichtung eignet sich außerdem hervorragend zur Transportkühlung. Sie ist unabhängig von einer permanenten Energieversorgung in der Kalthaltungsphase zu betreiben. Darüber hinaus ist der Aufbau der Vorrichtung aus wenigen Komponenten einfach und robust gewählt, was den Anforderungen an einen Transportcontainer im Hinblick auf Transportgewicht und Haltbarkeit entgegenkommt.The device according to the invention is also ideal for transport cooling. It must be operated independently of a permanent power supply in the cold holding phase. In addition, the structure of the device from a few components is simple and robust, which meets the requirements of a transport container in terms of transport weight and durability.

Im Einzelnen zeigt Figur 1 ein Kühlmodul 2 mit einem Kühlmittelreservoir 3 und einem unten an das Kühlmittelreservoirs 3 angrenzenden Hohlraum 4, der eine eutektische Kühlsole enthält und durch die Platte 10 vom Kühlmittelreservoir 3 getrennt ist. Die Platte 10 ist aus Stahl oder Edelstahl, gefertigt, wodurch ein guter Wärmeübergang zwischen dem Kühlmittel (z. B. flüssigen Stickstoff) und der eutektischen Kühlsole ermöglicht wird. Der Wärmeübergang findet dabei in der Hauptsache durch direkte Wärmeleitung über das Metall statt. Besonders vorteilhaft wird das gesamte Kühlmodul aus Stahl gefertigt.In detail shows FIG. 1 a cooling module 2 with a coolant reservoir 3 and a cavity 4 adjoining the coolant reservoir 3 at the bottom, which contains a eutectic cooling brine and is separated from the coolant reservoir 3 by the plate 10. The plate 10 is made of steel or stainless steel, allowing good heat transfer between the coolant (eg, liquid nitrogen) and the eutectic brine. The heat transfer takes place mainly by direct heat conduction through the metal. Particularly advantageous is the entire cooling module made of steel.

Des Weiteren sind in der Figur 1 Mittel 5 (Befüllstutzen 5) zur Befüllung des Kühlmittelreservoirs 3 mit flüssigem Stickstoff sowie Mittel 6 (Entgasungsöffnung 6) zur Ableitung von verdampftem Stickstoff aus dem Kühlmittelreservoir 3 vorgesehen. Der abgeleitete Stickstoff prallt gegen das Mittel 12 zur Führung des Kaltgasstroms, das in diesem Beispiel als Kappe 12 ausgebildet ist, die nicht fest mit der Entgasungsöffnung 6 verbunden ist, sondern beim Ausströmen des gasförmigen Stickstoffs von der Entagsungsöffnung beabstandet ist (vgl. Figur 1 und Figur 2), wodurch ein Ausströmen bei gleichzeitiger Änderung der Strömungsrichtung ermöglicht wird. Dadurch wird eine Aufprallen der Gasströmung auf die Innenseite der oberen Wand 1a des Behälters 1 verhindert. Der Behälter 1 ist im Ganzen in der Figur 4 schematisch dargestellt.Furthermore, in the FIG. 1 Means 5 (filling nozzle 5) for filling the coolant reservoir 3 with liquid nitrogen and means 6 (degassing 6) for discharging evaporated nitrogen from the coolant reservoir 3 are provided. The discharged nitrogen bounces against the means 12 for guiding the cold gas flow, which is formed in this example as a cap 12 which is not fixedly connected to the vent 6, but at the outflow of gaseous nitrogen from the Entagsungsöffnung is spaced (see. FIG. 1 and FIG. 2 ), whereby an outflow while changing the flow direction is made possible. As a result, impact of the gas flow on the inside of the upper wall 1a of the container 1 is prevented. The container 1 is in the whole in the FIG. 4 shown schematically.

An den ebenfalls in der Figur 1 gezeigten Pumpstutzen 7 kann eine Vakuumpumpe angeschlossen werden, die in dem Zwischenraum 13 ein Vakuum erzeugt, wodurch das Kühlmittelreservoir 3 wärmeisoliert wird. Darüber hinaus ist eine Befülleinrichturung 14 zur Befüllung des Hohlraums 4 mit eutektischer Kühlsole gezeigt.To the also in the FIG. 1 shown pump nozzle 7, a vacuum pump can be connected, which generates a vacuum in the intermediate space 13, whereby the coolant reservoir 3 is thermally insulated. In addition, a filling device 14 for filling the cavity 4 with eutectic cooling brine is shown.

Die Figur 2 zeigt eine Draufsicht aus das Kühlmodul 3, in der ebenfalls der Befüllstutzen 5, die Entgasungsöffnung 6 mit der Kappe 12, der Pumpstutzen 7 sowie die Befülleinrichtung 14 gezeigt sind.The FIG. 2 shows a plan view of the cooling module 3, in which also the filling nozzle 5, the vent 6 with the cap 12, the pump nozzle 7 and the filling device 14 are shown.

In der Figur 3 ist ein Querschnitt durch das Kühlmodul 3 gezeigt, der durch eine vertikale Schnitteben entstanden ist, die senkrecht auf der Schnitteben des Querschnitts aus der Figur 1 steht. Zusätzlich zu den bereits bei der Figur 1 beschriebenen Elementen sind in der Figur 3 vertikale Stege 11 gezeigt. Die vertikalen Stege 11 verbessern den Wäremübertrag aus dem Kühlmittelreservoir über die Platte 10 zur eutektischen Kühlsole, die sich im Hohlraum 4 befindet.In the FIG. 3 is shown a cross section through the cooling module 3, which is caused by a vertical Schnittbenben perpendicular to the Schnittbenben the cross section of the FIG. 1 stands. In addition to those already at the FIG. 1 described elements are in the FIG. 3 vertical webs 11 shown. The vertical webs 11 improve the heat transfer from the coolant reservoir via the plate 10 to the eutectic cooling brine, which is located in the cavity 4.

Die Figur 4 zeigt einen Behälter 1 mit einem Kühlmodul 2 wie es in den Figuren 1 bis 3 gezeigt ist sowie darüber hinaus einen Raum 15 zur Aufnahme eines auf einer bestimmten Temperatur zu haltenden Kühlguts 8. Der Behälter 1 ist bevorzugt als Thermobehälter 1 ausgebildet, was bedeutet, dass er mit einer thermischen Isolierung ausgestattet ist und meist aus Kunststoffmaterialien aufgebaut ist. Mit besonderem Vorteil ist der Raum 15 für das Kühlgut 8 im unteren Bereich des Behälters 1 angeordnet, während das Kühlmodul 2 bevorzugt im oberen Bereich des Behälters 1 angebracht ist. Dadurch wird eine gute Verteilung der vom Kühlmodul 2 abgegebenen Kälte im Inneren des Behälters 1 erreicht. Zusätzlich ist eine vorteilhafte Isolierung 9 der Außenwände des Behälters 1 gezeigt. Nicht dargestellt ist die den Behälter 1 verschließende Tür, durch die das Kühlgut 8 eingebracht und entnommen werden kann sowie über deren Abdichtung verdampftes Kältemittel, welches in den Raum 15 geleitet wurde, abgegeben werden kann, wodurch ein Druckanstieg im Raum 15 vermieden wird. Desweiteren zeigt die Figur 4 zwei Führungsschienen 16 an den Innenflächen der Seitenwände eines Behälters 1, an denen das Kühlmodul 2 entnehmbar im Behälter 1 angebracht ist.The FIG. 4 shows a container 1 with a cooling module 2 as in the FIGS. 1 to 3 The container 1 is preferably designed as a thermo container 1, which means that it is equipped with a thermal insulation and is usually constructed of plastic materials. With particular advantage, the space 15 is arranged for the refrigerated goods 8 in the lower region of the container 1, while the cooling module 2 is preferably mounted in the upper region of the container 1. This results in a good distribution of the output from the cooling module 2 in the cold Inside the container 1 reaches. In addition, an advantageous insulation 9 of the outer walls of the container 1 is shown. Not shown is the container 1 closing door, through which the refrigerated goods 8 can be introduced and removed and on the seal evaporated refrigerant, which was passed into the room 15, can be discharged, whereby a pressure increase in the space 15 is avoided. Furthermore, the shows FIG. 4 two guide rails 16 on the inner surfaces of the side walls of a container 1, where the cooling module 2 is removably mounted in the container 1.

Insgesamt werden sehr gute Kalthaltungseigenschaften erzielt, wodurch sich ein erfindungsgemäß ausgeführter Behälter 1 als zur Transportkühlung von empfindlichem Kühlgut, z. B. empfindichen Lebensmitteln wie Frischgemüse, besonders geeignet erweist.Overall, very good cold holding properties are achieved, resulting in an inventively executed container 1 as for the transport cooling of sensitive refrigerated goods, z.
