Description
Die Erfindung betrifft eine Thermosiphonanlage eines mindestens zwei Wärmequellen aufweisenden wärmeerzeugenden Systems.The invention relates to a thermosyphon system of at least two heat sources having heat generating system.
Eine Anwendung ist z. B. bei Transformatoren, speziell Trocken-Transformatoren gegeben, welche - gegebenenfalls zusammen mit anderen Wärmequellen - ein wärmeerzeugendes System bilden.An application is z. As in transformers, especially dry-type transformers, which - possibly together with other heat sources - form a heat-generating system.
Die Kühlung eines wärmeerzeugenden Systems kann in vielfältiger Weise erfolgen, z. B. durch natürliche oder forcierte Kühlung oder mit Hilfe externer Kühler, z. B. Luft-Wasser-Kühler. Weitere Möglichkeiten bestehen in der Verwendung von Thermosiphons in einer Anordnung als Luft-Luft-Thermosiphon oder als Luft-Wasser-Thermosiphon. Dabei ist für jede Wärmequelle ein Verdampfer vorgesehen, welcher über einen geschlossenen Kühlmittel-Kreislauf die aufgenommene Wärme an einen Kondensator abgibt. In einem wärmeerzeugenden System mit mehreren Wärmequellen muss eine geeignete Kühlung für alle Komponenten vorgesehen werden. Werden mehrere Wärmequellen mit derartigen Thermosiphons versehen, so bedeutet dies bei Einsatz von Luft-Luft-Thermosiphons die Verwendung eines Lüfters für jeden Verdampfer und für jeden Kondensator.The cooling of a heat generating system can be done in many ways, for. B. by natural or forced cooling or with the help of external coolers, z. B. air-water cooler. Other options include the use of thermosyphons in an arrangement as an air-air thermosyphon or as an air-water thermosyphon. In this case, an evaporator is provided for each heat source, which emits the absorbed heat to a capacitor via a closed coolant circuit. In a heat generating system with multiple heat sources, appropriate cooling must be provided for all components. If several heat sources are provided with such thermosyphons, this means the use of a fan for each evaporator and for each capacitor when using air-air thermosyphons.
Der Erfindung liegt die die Aufgabe zugrunde, eine vereinfachte und optimierte Thermosiphonanlage eines mindestens zwei Wärmequellen aufweisenden wärmeerzeugenden Systems anzugeben.The invention has for its object to provide a simplified and optimized Thermosiphonanlage a at least two heat sources having heat generating system.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst durch eine Thermosiphonanlage eines mindestens zwei Wärmequellen aufweisenden wärmeerzeugenden Systems, bei welchem ein einziger, allen Wärmequellen zugeordneter gemeinsamer Kondensator vorgesehen ist.This object is achieved by a thermosyphon system of at least two heat sources having heat generating system, in which a single, all heat sources associated common capacitor is provided.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass die Anzahl erforderlicher Baukomponenten reduziert wird. Die Thermosiphon-Technologie erlaubt die räumliche Trennung von Verdampfern und Kondensatoren, wobei beide Komponenten durch Rohre miteinander verbunden werden, durch die das Kühlmittel vom Verdampfer zum Kondensator und zurück strömen kann. Es werden die Kondensatoren verschiedener, unterschiedlichen Wärmequellen zugeordneter Kühler so zusammengefasst, dass sie durch einen einzigen Lüfter oder Luftfördereinrichtung oder -mechanismus oder einen einzigen externen Wasserkreislauf gekühlt werden können. Alternativ hierzu können auch mehrere Wärmequellen mit einem einzigen gemeinsamen Kühler versehen sein und einen gemeinsamen Kühlkreislauf haben. Allgemein können sowohl Luft-Luft-Thermosiphons als auch als Luft-Wasser-Thermosiphons zum Einsatz gelangen.The advantages achieved by the invention are, in particular, that the number of required structural components is reduced. The thermosiphon technology allows the spatial separation of evaporators and condensers, whereby both components are connected by pipes, through which the refrigerant from the evaporator to the condenser and back flow. The condensers of different radiators associated with different heat sources are grouped together so that they can be cooled by a single fan or air conveyor or mechanism or a single external water loop. Alternatively, several heat sources may be provided with a single common radiator and have a common cooling circuit. In general, both air-air thermosyphon as well as air-water thermosiphon can be used.

Ein erster Lüfter 20 oder Luftfördereinrichtung oder -mechanismus unterstützt den Wärmeaustausch zwischen dem Verdampfer 19 und der ersten Maschine 18, d. h. er unterstützt die innere Luftzirkulation und damit die Kühlung der Maschine 18. Ein zweiter Lüfter 23 oder Luftfördereinrichtung oder -mechanismus unterstützt den Wärmeaustausch zwischen dem Verdampfer 22 und der zweiten Maschine 21, d. h. er unterstützt die innere Luftzirkulation und damit die Kühlung der Maschine 21.

Zur Abfuhr der von den Wärmequellen 34, 35 sowie gegebenenfalls weiteren Wärmequellen erzeugten Wärmeenergie an die Außenatmosphäre ist ein Luft-Luft-Thermosiphon 36 einer Thermosiphonanlage 29 vorgesehen, welcher als "einstückiges" Gerät ausgebildet ist, dessen Verdampfer 37 sich innerhalb des Gehäuses 33 befindet und dessen Kondensator 39 sich außerhalb des Gehäuses 33 befindet. Der Kondensator 39 ist quasi als Erweiterung oberhalb des Verdampfers 37 ausgeführt und auf dem Dach der Gondel angeordnet. Ein innerhalb des Gehäuses 33 befindlicher Zentrallüfter 38 oder Luftfördereinrichtung oder -mechanismus dient der (inneren) Luftzirkulation innerhalb des Gehäuses 33 und unterstützt die Abgabe der von den Wärmequellen 34, 35 erzeugten Wärmeenergie an den Verdampfer 37 und damit deren Kühlung. Die Rückkühlung des Kondensators 39 erfolgt unter Einsatz eines die äußere Luftzirkulation unterstützenden Lüfters 40 oder Luftfördereinrichtung oder -mechanismus, welcher den Kondensator 39 mit Luft der Außenatmosphäre beaufschlagt.To dissipate the heat energy generated by the

- Selbstverständlich können anstelle eines Lüfters oder Luftfördereinrichtung oder -mechanismus jeweils auch mehrere Lüfter eingesetzt werden. Gegebenenfalls kann man insbesondere bei der inneren Luftzirkulation auch bei geeigneter Gestaltung mit natürlicher Luftströmung auskommen und auf einen Lüfter verzichten - was reduzierte Kühlleistung zur Folge hat. Speziell bei einer Windenergieanlage (siehe
