Description
Kühleinrichtung für Windenergieanlagen Cooling device for wind turbines
Die Erfindung betrifft eine Kühleinrichtung für Windenergieanlagen mit auf einem Turm drehbar angeordnetem Maschinenhaus und mit mindestens einem mit diesem verbundenen Wärmetauscher, der Bestandteil eines Kühlkreislaufs ist und für eine Wärmeabgabe an die Umgebung der äußeren Luftströmung ausgesetzt ist. The invention relates to a cooling device for wind turbines with rotatably mounted on a tower engine house and with at least one associated with this heat exchanger, which is part of a cooling circuit and is exposed to heat dissipation to the environment of the outer air flow.
In den im Maschinenhaus befindlichen Aggregaten, wie Getriebe, Generatoren usw., fallen im Betrieb Verluste an, so dass für eine Abfuhr von Verlustwärme an die Umgebung Sorge getragen werden muss. Im Stand der Technik sind hierfür Kühleinrichtungen vorgesehen, die in einem Kreislauf ein Kühlmedium an betreffenden Wärmequellen vorbeiführen und einen oder mehrere Wärmetauscher besitzen, denen Ventilatoren vor- oder nachgesetzt sind, um einen entsprechenden Durchstrom von Kühlluft zu erzeugen. In Windenergieanlagen ergibt sich betriebsbedingt zusätzlich die Mög- lichkeit, die herrschende Windströmung, deren Stärke mit der Erzeugung von Verlustwärme korreliert, zum Durchströmen von Wärmetauschern zu nutzen und somit die Effektivität des Kühlsystems zu verbessern. Dementsprechend ist es Stand der Technik, einen oder mehrere Wärmetauscher an der Außenseite des Maschinenhauses anzuordnen, so dass er, ohne dass aktive Mittel wie Gebläse erforderlich sind, von Kühlluft durchströmbar ist.
Ausgehend von diesem Stand der Technik stellt sich die Erfindung die Aufgabe, eine Kühleinrichtung für Windenergieanlagen zur Verfügung zu stellen, die sich durch eine weiter verbesserte Energiebilanz auszeichnet. Erfindungsgemäß ist diese Aufgabe durch eine Kühleinrichtung gelöst, die die Merkmale des Patentanspruchs 1 in seiner Gesamtheit aufweist. In the units located in the nacelle, such as gearboxes, generators, etc., incurred during operation losses, so that care must be taken to dissipate heat loss to the environment. In the prior art cooling devices are provided for this purpose, which lead in a circuit a cooling medium to relevant heat sources and have one or more heat exchangers, which fans upstream or downstream, to produce a corresponding flow of cooling air. In the case of wind turbines, due to operational reasons, it is additionally possible to utilize the prevailing wind flow, the strength of which correlates with the generation of heat loss, for the flow through heat exchangers and thus to improve the effectiveness of the cooling system. Accordingly, it is state of the art to arrange one or more heat exchangers on the outside of the machine house so that it can be flowed through by cooling air without the need for active means such as blowers. Based on this prior art, the invention has the object to provide a cooling device for wind turbines, which is characterized by a further improved energy balance. According to the invention this object is achieved by a cooling device having the features of claim 1 in its entirety.
Gemäß dem kennzeichnenden Teil des Anspruchs 1 besteht eine wesentliche Besonderheit der Erfindung darin, dass zumindest ein der äußeren Luft- Strömung ausgesetzter Wärmetauscher an einer Stelle angeordnet ist, an der die Luftströmung durch die aus der Geometrie des Turmes resultierende Verdrängungswirkung beschleunigt ist. Diese Anordnung des Wärmetauschers nutzt den Umstand aus, dass der Turm bei der üblichen, rohrförmi- gen Gestalt wie ein kreiszylindrischer Körper umströmt wird, wobei sich zu beiden Seiten einer den Staubereich bildenden, durch die Rotorachse definierten Vertikalebene, am Umfang des Turmes Strömungsbereiche stark beschleunigter Strömung ergeben. Die erfindungsgemäß vorgesehene Anordnung eines oder mehrerer Wärmetauscher derart, dass er sich zumindest teilweise in einem solchen Strömungsbereich befindet, führt zu einer ver- besserten Durchströmung und damit verstärkter Wärmeabgabe an die Umgebungsluft. Dank der so verbesserten Kühlwirkung können zusätzliche, aktive Mittel zur Verstärkung der Luftströmung mit geringerer Leistung benutzt werden oder ganz in Wegfall kommen, so dass insgesamt eine Verbesserung der Energiebilanz erreicht wird. According to the characterizing part of claim 1, a significant feature of the invention is that at least one of the outer air flow exposed heat exchanger is disposed at a position at which the air flow is accelerated by the resulting from the geometry of the tower displacement effect. This arrangement of the heat exchanger takes advantage of the fact that the tower is flowed around in the usual, tubular shape like a circular cylindrical body, with greatly accelerated flow areas on both sides of a vertical plane defined by the rotor axis and forming a congestion area Flow yield. The inventively provided arrangement of one or more heat exchangers such that it is at least partially in such a flow region, leads to an improved flow and thus increased heat transfer to the ambient air. Thanks to the improved cooling effect, additional, active means for increasing the flow of air at lower power can be used or eliminated altogether, so that an overall improvement in the energy balance is achieved.
Vorteilhafterweise ist der jeweilige Wärmetauscher benachbart zu der äußeren Oberfläche des Turmes angeordnet, so dass er sich großteils innerhalb des Bereichs der am stärksten beschleunigten Strömung befindet. Mit besonderem Vorteil kann die Anordnung so getroffen sein, dass der jeweilige Wärmetauscher unterhalb des Maschinenhauses in einer Ebene
angeordnet ist, die zu der der Achsrichtung des Rotors entsprechenden Hauptwindrichtung senkrecht oder in einem Winkel hierzu geneigt ist. Der Bereich beschleunigter Strömung wird dadurch optimal für die Durchströmung des jewei ligen Wärmetauscher genutzt. Advantageously, the respective heat exchanger is located adjacent to the outer surface of the tower so that it is largely within the region of the fastest accelerated flow. With particular advantage, the arrangement can be made such that the respective heat exchanger below the machine house in a plane is arranged, which is inclined to the axis of rotation of the rotor corresponding to the main wind direction perpendicular or at an angle thereto. The range of accelerated flow is thus optimally used for the flow through the jewei time heat exchanger.
In besonders vorteilhafter Weise kann beidseits des Turmes zumindest ein Wärmetauscher angeordnet sein, der vorzugsweise unmittelbar an der Unterseite des Maschinenhauses befestigt ist. Ungeachtet der durch die beschleunigte Strömung erreichten Verbesserung des Wärmeüberganges kann dem jeweiligen Wärmetauscher zusätzlich eine Einrichtung zur Strömungsführung und/oder—aufbereitung zugeordnet sein. In vorteilhafter Weise können diesbezüglich am jeweiligen Wärmetauscher eine oder mehrere Strömungsleitflächen vorgesehen sein. In a particularly advantageous manner can be arranged on both sides of the tower at least one heat exchanger, which is preferably attached directly to the bottom of the machine house. Regardless of the improvement achieved by the accelerated flow of the heat transfer, the respective heat exchanger can additionally be assigned a device for flow guidance and / or treatment. Advantageously, one or more flow control surfaces can be provided in this regard on the respective heat exchanger.
Alternativ oder zusätzlich hierzu kann ein dem jeweiligen Wärmetauscher vor- oder nachgesetzter Ventilator als aktiver Strömungsverstärker zugeord- net sein. As an alternative or in addition to this, a fan which is upstream or downstream of the respective heat exchanger can be assigned as an active flow amplifier.
Nachstehend ist die Erfindung anhand der Zeichnung im Einzelnen erläutert. Es zeigen: The invention is explained in detail below with reference to the drawing. Show it:

Turm der Windanlage umströmenden Luft, wobei Beispiele der erfindungsgemäßen Anordnung von Wärmetauschern eingezeichnet sind. Tower of the wind turbine surrounding air, examples of the inventive arrangement of heat exchangers are shown.
Die F ig.1 und 2 zeigen in vereinfachter, skizzenhafter Darstellung den oberen Teil einer Windenergieanlage mit einem Maschinenhaus 1 , das in der üblichen Weise auf einem Turm 3 drehbar angeordnet ist, so dass sich die Drehachse 5 des Rotors 7 auf die Hauptwindrichtung einstellen kann. Von einem Kühlkreislauf, der zur Kühlung von Aggregaten vorgesehen ist, die sich im Inneren des Maschinenhauses 1 befinden und während des Betriebs Verlustwärme erzeugen, sind in den Figuren lediglich äußere Wärmetauscher 9 dargestellt, während der übrige, im Maschinenhaus 1 befindliche Kühlkreislauf, ebenso wie die im Maschinenhaus 1 befindlichen Aggregate nicht dargestellt sind, da diese Komponenten sämtlich dem Stand der Technik entsprechen können. Bei dem vorliegenden Beispiel sind zwei Wärmetauscher 9 mit der Unterseite 1 1 des Maschinenhauses 1 so verbunden, dass sie sich beidseits neben dem Turm 3 befinden, wobei, wie aus Fig.2 entnehmbar ist, die Wärmetauscher 9 zu der äußeren Oberfläche 1 3 des Turmes 3 eng benachbart sind. FIGS. 1 and 2 show, in a simplified, sketch-like illustration, the upper part of a wind turbine with a machine house 1, which is rotatably mounted on a tower 3 in the usual way, so that the axis of rotation 5 of the rotor 7 can be adjusted in the main wind direction , From a cooling circuit which is provided for cooling of units, which are located inside the machine house 1 and generate heat loss during operation, only external heat exchanger 9 are shown in the figures, while the rest, located in the machine house 1 cooling circuit, as well as Aggregates located in the machine house 1 are not shown, since these components can all correspond to the state of the art. In the present example, two heat exchangers 9 are connected to the bottom 1 1 of the machine house 1 so that they are located on both sides of the tower 3, wherein, as can be seen from Figure 2, the heat exchanger 9 to the outer surface 1 3 of the tower 3 are closely adjacent.
Fig.3 veranschaulicht das Strömungsbild bei der Umströmung eines stationären Kreiszylinders, wie er vorliegend durch den Turm 3 der Windener- gieanlage verkörpert ist. Die in Fig.3 nur teilweise bezifferten Stromlinien 1 5 verlaufen vor Erreichen des Turmes 3 zueinander parallel, d.h. mit über
das Strömungsfeld gleicher Strömungsgeschwindigkeit. Bei Annäherung an den an der Vorderseite des Turmes 3 befindlichen Staubereich 1 7 erfolgt durch den Verdrängungseffekt des Turmes 3 das Zusammenrücken der Stromlinien 15, was bei Unterschallströmungen eine Beschleunigung der Strömung zur Folge hat. Beidseits des Turmes 3 bi lden sich somit Kontraktionsbereiche 1 9 beträchtlich erhöhter Strömungsgeschwindigkeit. Im Nachlauf hinter dem Turm 3 bildet sich eine Turbulenzzone 21 mit Ablösewirbeln. Erfindungsgemäß sind die Wärmetauscher 9 so angeordnet, dass sie innerhalb der beschleunigten Kontraktionsbereiche 19 gelegen sind. Die Fig.3 zeigt im oberen Teil einen Wärmetauscher 9, der innerhalb einer Ebene 23 angeordnet ist, die zu der der Achse 5 des Rotors 7 entsprechenden 3 illustrates the flow pattern during the flow around a stationary circular cylinder, as embodied herein by the tower 3 of the wind energy plant. The only partially quantified in Figure 3 streamlines 1 5 run parallel to each other before reaching the tower 3, ie with over the flow field of the same flow velocity. When approaching the located at the front of the tower 3 storage area 1 7 is carried out by the displacement effect of the tower 3, the convergence of the streamlines 15, which has an acceleration of the flow in subsonic flows result. On both sides of the turret 3, thus, contraction regions 1 9 are considerably increased flow velocity. In the wake behind the tower 3 forms a turbulence zone 21 with separation vortices. According to the invention, the heat exchangers 9 are arranged so that they are located within the accelerated contraction regions 19. 3 shows in the upper part of a heat exchanger 9, which is arranged within a plane 23 corresponding to that of the axis 5 of the rotor 7
Hauptwindrichtung senkrecht ist. An der unteren Seite der Fig.3 ist ein demgegenüber abgewandeltes Beispiel dargestellt, bei dem sich der Wärmetauscher 9 in einer gegenüber der Ebene 23 um einen, vorzugsweise kleinen Winkel α geneigten Ebene befindet. Zusätzlich sind bei dieser Variante Einrichtungen zur Strömungsführung sowie zur Strömungsaufbereitung dem Wärmetauscher 9 zugeordnet. Für die Strömungsführung weist der Wärmetauscher 9, der in der Art eines Plattenwärmetauschers ausgebildet sein kann, innere Führungslamellen 25 (lediglich je eine in Fig.3 beziffert) auf. Am äußeren Rand des Wärmetauschers 9 kann zudem eine Strömungsleitfläche 27 vorgesehen sein, die sich, wie beispielhaft in Fig.3 gezeigt, entgegen der Hauptwindrichtung erstreckt und die Strömung zusätzlich intensiviert. Die Fig.3 zeigt weiterhin, dass als Einrichtung zur aktiven Strömungsaufbereitung ein Ventilator 29 oder mehrere Ventilatoren dem unteren Wärmetauscher 9 vorgesetzt oder nachgesetzt sein können. Ein solcher oder solche kann bzw. können zusätzlich zu den Lamellen 25 und/oder der Leitfläche 27 oder alternativ hierzu vorgesehen sein. Entspre- chende Einrichtungen zur Strömungsführung und -aufbereitung können auch an dem in Fig.3 oben liegenden Wärmetauscher 9 vorgesehen sein. In
jedem Fall führt die erfindungsgemäße Anordnung einer oder mehrerer Wärmetauscher 9 in einem Bereich, in dem die Geometrie des Turmes 3 eine Konzentration der Stromlinien 1 5 der Luftströmung verursacht, so dass eine Zone beschleunigter Strömung entsteht, zu einer Verbesserung der Wärmeabgabe des betreffenden Wärmetauschers 9 an die Umgebungsluft. Ferner können andere Wärmetauscherbauarten je nach Bedarfsfall zum Einsatz kommen.
Main wind direction is vertical. On the lower side of Figure 3, a contrast, modified example is shown, in which the heat exchanger 9 is in a relation to the plane 23 at a, preferably small angle α inclined plane. In addition, in this variant, devices for flow guidance and for flow conditioning are associated with the heat exchanger 9. For the flow guide, the heat exchanger 9, which may be designed in the form of a plate heat exchanger, inner guide plates 25 (only one each numbered in Figure 3) on. At the outer edge of the heat exchanger 9 may also be provided a flow guide 27, which, as shown by way of example in Figure 3, extends against the main wind direction and intensifies the flow additionally. FIG. 3 further shows that, as a device for active flow conditioning, a fan 29 or a plurality of fans can be preset or set downstream of the lower heat exchanger 9. Such or such may be provided in addition to the fins 25 and / or the guide surface 27 or alternatively thereto. Corresponding devices for flow guidance and conditioning can also be provided on the heat exchanger 9 located at the top in FIG. In In any case, the arrangement according to the invention of one or more heat exchangers 9 in an area in which the geometry of the tower 3 causes a concentration of the flow lines 1 5 of the air flow, so that a zone of accelerated flow arises, leads to an improvement in the heat output of the heat exchanger 9 in question the ambient air. Further, other types of heat exchangers may be used as needed.
