KUHLVORRICHTUNGCOOLING DEVICE
Die Erfindung betrifft eine Kühlvorrichtung, umfassend einen durch Rohre geführten Flüssigkeitskreislauf, der zur Kühlung der Flüssigkeit durch wenigstens eine Kühlan¬ ordnung geführt ist.The invention relates to a cooling device comprising a liquid circuit which is guided through pipes and which is led through at least one cooling arrangement for cooling the liquid.
Müssen mehrere Geräte, wie zum Beispiel Werkzeugmaschinen oder dergleichen betriebsmäßig gekühlt werden, so werden die Geräte vielfach an einen gemeinsamen Flüssigkeits¬ kreislauf angeschlossen, in welchem eine von einer Kühl¬ anordnung gekühlte Flüssigkeit zirkuliert. Die Kühlanord¬ nung kann beispielsweise als Berieselungskühler ausgebil¬ det sein oder aber -eine Kältemaschine umfassen. Herkömm¬ liche Kühlanordnungen beanspruchen, selbst wenn sie kompakt aufgebaut sind, eine vergleichsweise große Grund¬ fläche der Fabrikationshalle, in welcher die Geräte oder Maschinen aufgestellt sind.If several devices, such as machine tools or the like, have to be operationally cooled, the devices are often connected to a common liquid circuit in which a liquid cooled by a cooling arrangement circulates. The cooling arrangement can be designed, for example, as a sprinkler cooler or else comprise a refrigerator. Conventional cooling arrangements, even if they are compact, take up a comparatively large base area of the manufacturing hall in which the devices or machines are installed.
Es ist Aufgabe der Erfindung, einen einfachen Weg zu zeigen, wie mit geringem Bedarf an Grundfläche die Kühl¬ leistung einer Kühlvorrichtung der vorstehenden Art verbessert werden kann.It is an object of the invention to show a simple way of how the cooling capacity of a cooling device of the above type is required with a small footprint can be improved.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zumindest eine Teillänge der Rohre des Flüssigkeitskreis- laufs zur Bildung der Kühlanordnung meanderförmig in einer im wesentlichen vertikalen Ebene verläuft. Der Erfindung liegt die Idee zugrunde, ohnehin für den Flüs¬ sigkeitskreislauf erforderliche Rohre durch meanderförmi- ge Gestaltung zu verlängern und zugleich zur Kühlung mitauszunutzen. Die zu kühlenden Geräte sind vorzugsweise im Bereich des meanderförmigen Teils des Rohrs vorzugs¬ weise im Bereich von Verbindungsstücken von zueinander parallel verlaufenden Rohrabschnitten angeschlossen. Der Flüssigkeitskreislauf kann direkt durch die zu kühlenden Geräte geführt werden, wie dies auch beispielsweise dann der Fall ist, wenn die Flüssigkeit des Kühlkreislaufs Herstellungsprodukt eines Geräts der Nahrungsmittel¬ bzw. Getränkeindustrie ist, oder aber die zu kühlenden Geräte werden über einen zweiten Flüssigkeitskreislauf und einen Wärmetauscher an den Flüssigkeitskreislauf des meanderförmigen Rohrs angeschlossen.This object is achieved according to the invention in that at least a partial length of the tubes of the liquid circuit runs in a meandering manner to form the cooling arrangement in an essentially vertical plane. The invention is based on the idea of extending the pipes required for the liquid circuit anyway by means of a meandering design and at the same time using them for cooling. The devices to be cooled are preferably connected in the area of the meandering part of the pipe, preferably in the area of connecting pieces of pipe sections running parallel to one another. The liquid circuit can be passed directly through the devices to be cooled, as is also the case, for example, if the liquid of the cooling circuit is a product of a device of the food or beverage industry, or else the devices to be cooled are passed through a second liquid circuit and one Heat exchanger connected to the liquid circuit of the meandering tube.
Der durch das meanderförmige Rohr geführte Flüssigkeits¬ kreislauf kann unmittelbar durch eine Kältemaschine geführt sein; die Kältemaschine kann aber ebenfalls über einen Wärmetauscher und einen dritten Flüssigkeitskreis¬ lauf angeschlossen sein.The liquid circuit guided through the meandering tube can be led directly through a refrigerator; however, the refrigerator can also be connected via a heat exchanger and a third liquid circuit.
In einer bevorzugten Ausgestaltung ist das meanderförmige Rohr insbesondere einschließlich der als Verbindungsstücke ausgenutzten Wärmetauscher zu einer für sich transportab¬ len Baueinheit ausgesteift. Dies ermöglicht einerseits die Vorfertigung und andererseits die Verwendung dieser Baueinheit als Bestandteil eines Wand-Fertigteils einer Gebäudewand. Das meanderförmige Rohr kann in einem im wesentlichen scheibenförmigen, flachen Behälter untergebracht sein, durch den ein in Wärmetauschkontakt mit den Rohren ste¬ hender Flüssigkeitskühlkreislauf geführt ist. Diese Variante erlaubt insbesondere bei Anwendungen in der Lebensmittelindustrie eine einwandfreie Trennung der durch das meanderförmige Rohr geführten Flüssigkeit, beispielsweise eines Getränks und der die Kälte zuführen¬ den Flüssigkeit des durch den Behälter geführten Kühl- kreislaufs. Insbesondere lassen sich in der vorstehenden Weise Berieselungskühler mit geringem Grundflächen-Platz¬ bedarf aufbauen.In a preferred embodiment, the meandering tube, in particular including the heat exchangers used as connecting pieces, is stiffened to form a transportable unit. On the one hand, this enables prefabrication and, on the other hand, the use of this structural unit as part of a prefabricated wall part of a building wall. The meandering tube can be accommodated in an essentially disk-shaped, flat container through which a liquid cooling circuit in heat exchange contact with the tubes is guided. This variant allows, in particular in applications in the food industry, a perfect separation of the liquid passed through the meandering tube, for example a drink, and the liquid supplying the cold from the cooling circuit passed through the container. In particular, sprinkler coolers with a small footprint can be constructed in the above manner.
Im folgenden werden Ausführungsbeispiele der Erfindung anhand einer Zeichnung näher erläutert. Hierbei zeigt:Exemplary embodiments of the invention are explained in more detail below with reference to a drawing. Here shows:
Fig. 1 eine schematische Darstellung einer erfindungs¬ gemäßen Kühlvorrichtung und Fig. 2 eine schematische Darstellung einer als Be- rieselungskühler aufgebauten erfindungsgemäßen1 shows a schematic illustration of a cooling device according to the invention, and FIG. 2 shows a schematic illustration of a cooling device according to the invention constructed as a spray cooler
- Kühlvorrichtung.- cooling device.
Fig. 1 zeigt eine Kühlvorrichtung für die Kühlung mehre¬ rer Geräte 1, wie zum Beispiel Werkzeugmaschinen oder dergleichen, die über Wärmetauscher 3 an einen gemeinsa¬ men Kühlkreislauf 5 angeschlossen sind. Der Kühlkreislauf 5 umfaßt ein im Kreislauf über einen Vorratsbehälter 7 für Kühlflüssigkeit geführtes Rohrsystem 9, in welchem, von einer Umwälzpumpe 11 umgewälzt, eine Kühlflüssigkeit, beispielsweise Wasser, zirkuliert. Über wenigstens einen, vorzugsweise jedoch mehrere Wärmetauscher 13, ist eine Kältemaschine 15 zur Kühlung der in dem Rohrsystem 9 umgewälzten Flüssigkeit an das Rohrsystem 9 angekoppelt.1 shows a cooling device for cooling a plurality of devices 1, such as, for example, machine tools or the like, which are connected to a common cooling circuit 5 via heat exchangers 3. The cooling circuit 5 comprises a pipe system 9, which is circulated via a storage container 7 for cooling liquid and in which, circulated by a circulating pump 11, a cooling liquid, for example water, circulates. A refrigeration machine 15 for cooling the liquid circulated in the pipe system 9 is coupled to the pipe system 9 via at least one, but preferably several, heat exchangers 13.
Zur Minderung der von der Kältemaschine 15 aufzubringen- den Kühlleistung bildet eine Teillänge des Rohrsystems 9 einen Konvektionskühler 17, in dem zueinander parallele, horizontal angeordnete Rohrabschnitte 19 vertikal über¬ einander im wesentlichen mit einer gemeinsamen vertikalen Ebene angeordnet und an ihren Enden durch vertikaleTo reduce the amount to be applied by the refrigerator 15 In terms of cooling capacity, a partial length of the pipe system 9 forms a convection cooler 17, in which parallel, horizontally arranged pipe sections 19 are arranged vertically one above the other essentially with a common vertical plane and at their ends by vertical ones
Verbindungsstücke 21 und die an das Rohrsystem 9 ange¬ schlossenen Wärmetauscher 3 bzw. 13 zu einem meanderför¬ migen Rohr verbunden sind. Die Rohrabschnitte 19, 21 und die Wärmetauscher 3, 13 sind durch Rahmenelemente, insbe- sondere jedoch Wandplatten 23, zu einer für sich transpor¬ tablen Baueinheit miteinander verbunden. Die Baueinheit kann als Fertigwandteil eines Gebäudes ausgenutzt werden und über Anschlüsse 25, 27 an die übrige Installation des Rohrsystems 9 angeschlossen werden.Connecting pieces 21 and the heat exchangers 3 and 13 connected to the pipe system 9 are connected to form a meandering pipe. The pipe sections 19, 21 and the heat exchangers 3, 13 are connected to one another by frame elements, in particular, however, wall plates 23, to form a transportable unit. The structural unit can be used as a prefabricated wall part of a building and can be connected to the rest of the installation of the pipe system 9 via connections 25, 27.
Es versteht sich, daß in einer Variante der Kühlvorrich¬ tung die zu kühlenden Geräte 1 auch direkt an den Kühl- flüssigkeitskreislauf 5 angeschlossen sein können. Soweit die Kühlwirkung des meanderförmigen Rohrs bereits aus¬ reicht, kann die Kältemaschine 15 gegebenenfalls entfal¬ len.It goes without saying that, in a variant of the cooling device, the devices 1 to be cooled can also be connected directly to the cooling liquid circuit 5. If the cooling effect of the meandering tube is already sufficient, the refrigeration machine 15 can be omitted if necessary.
Fig. 2 zeigt einen Berieselungskühler 31, insbesondere für die Nahrungsmittelindustrie, der eine Kontamination des über ein Rohrsystem 33 aus einer Nahrungsmittelpro¬ duktionsmaschine 35 zur Kühlung zugeführte Nahrungsmit¬ telflüssigkeit mit hoher Sicherheit verhindert. Der Berieselungskühler 31 umfaßt ein platten- oder scheiben¬ förmiges, mit seiner Scheibenebene im wesentlichen verti- kal angeordnetes Gehäuse 37, in welchem ein meanderförmi- ges Rohr 39 angeordnet ist. Das meanderförmige Rohr 39 umfaßt vertikal übereinander angeordnete, horizontal verlaufende Rohrabschnitte 41, die an ihren Enden durch vertikale Verbindungsstücke 43 miteinander verbunden sind. Oberhalb des meanderförmigen Rohrs 39 ist ein mit einer Vielzahl Düsen 45 versehenes Berieselungsrohr 47 angeordnet. Das Berieselungsrohr 47 beregnet das meander¬ förmige Rohr 39 mit nahrungsmitteltechnisch unbedenkli¬ cher Flüssigkeit, wie zum Beispiel Wasser, die von einer Umwälzpumpe 49 von der Unterseite des Behälters 37 abge¬ zogen und im Kreislauf dem Berieselungsrohr 47 zugeführt wird. An diesen Kreislauf ist über einen Wärmetauscher 51 eine nicht näher dargestellte Kältemaschine angekoppelt. Die Trennung des Kühlmittelkreislaufs der Kältemaschine und des Rohrsystems 33 verhindert, daß bei einem Leck des Kältemittelkreislaufs der Kältemaschine deren Kältemittel in den Nahrungsmittelkreislauf gelangt. Der Berieselungs¬ kühler 31 bildet eine für sich transportable Baueinheit, die nur vergleichsweise geringe Grundfläche zum Aufstel- len benötigt.2 shows a sprinkler cooler 31, in particular for the food industry, which prevents contamination of the food liquid supplied for cooling via a pipe system 33 from a food production machine 35 with high certainty. The sprinkler cooler 31 comprises a plate-shaped or disk-shaped housing 37, which is arranged essentially vertically with its disk plane and in which a meandering tube 39 is arranged. The meandering tube 39 comprises vertically superposed, horizontally extending tube sections 41 which are connected to one another at their ends by vertical connecting pieces 43. Above the meandering tube 39 is a with a sprinkler pipe 47 provided with a plurality of nozzles 45. The sprinkler pipe 47 sprinkles the meandering pipe 39 with food-safe liquid, such as water, which is drawn off from the underside of the container 37 by a circulating pump 49 and is supplied to the sprinkler pipe 47 in the circuit. A refrigeration machine, not shown, is coupled to this circuit via a heat exchanger 51. The separation of the coolant circuit of the refrigeration machine and the pipe system 33 prevents the refrigerant circuit of the refrigeration machine from getting into the food circuit in the event of a leak in the refrigerant circuit. The sprinkler cooler 31 forms a unit which is transportable in itself and which requires only a comparatively small footprint for installation.
Bei den vorstehend erläuterten Ausführungsbeispielen der Kühlvorrichtung sind die horizontalen Rohrabschnitte 19 bzw. 41 länger als die vertikalen Verbindungsstücke. Alternativ können die längeren Rohrabschnitte aber auch vertikal angeordnet sein. In the exemplary embodiments of the cooling device explained above, the horizontal pipe sections 19 and 41 are longer than the vertical connecting pieces. Alternatively, the longer pipe sections can also be arranged vertically.
