Description

Die Erfindung betrifft ein Leitrad für Ventilatoren, insbesondere von Luftkühlem, das abstromseitig des Ventilatorlaufrades in geringem Abstand einen mit dem Ventilatorlaufrad axial fluchtenden, stationären Leitschaufelkranz aufweist, dessen Schaufeln so gekrümmt sind, dass sie die aus dem Laufrad austretenden Luftstrahl bündeln.The invention relates to a stator for fans, in particular of Luftkühlem, the downstream of the fan impeller at a short distance has a radially aligned with the fan impeller, stationary vane ring, the blades are curved so that they focus emerging from the impeller air jet.

Derartige Leiträder sind insbesondere aus dem (US-A-6309178) DE-GM 94 22 006, dem DE-GM 88 16 827, dem DE-GM 90 02 321 und dem EP 477 612 bekannt. Die bekannten Leiträder sind einteilige, insbesondere aus Kunststoff oder Metall bestehende Konstruktionen, die in der Regel gegossen oder gepresst sind und somit von Hause aus bestimmten Ventilator- bzw. Ventilatorgehäuseabmessungen zugeordnet sind. Im Fall von Beschädigungen eines oder mehrerer Flügel oder einer gewünschten Wurfweitenänderungen der hindurchtretenden Luft müssen sie als Ganzes ausgetauscht werden. Dies bedingt einen erheblichen Kostenaufwand.Such guide wheels are known in particular from (US-A-6309178) DE-GM 94 22 006, DE-GM 88 16 827, DE-GM 90 02 321 and EP 477 612. The known guide wheels are one-piece, in particular made of plastic or metal structures, which are usually cast or pressed and thus associated with home specific fan or fan housing dimensions. In the case of damage to one or more wings or a desired throw changes in the passing air, they must be replaced as a whole. This requires a considerable cost.

Die Aufgabe der Erfindung besteht deshalb darin, ein Leitrad zu entwickeln, das wesentlich kostengünstiger angefertigt und an sich ändernde Strömungsverhältnisse bzw. Luftmengendurchsatzverhältnisse ohne weiteres anpassbar ist.The object of the invention is to develop a stator, which is made much cheaper and readily adaptable to changing flow conditions or air flow rate ratios.

Dies geschieht erfindungsgemäß dadurch, dass der Leitschaufelkranz aus miteinander verbundenen Segmenten zusammengesetzt und dadurch variabel ist. Jedes Segment weist wenigstens eine Leitschaufel auf, die gewöhnlich aus einem räumlich gebogenen Blechteil besteht.This is done according to the invention in that the vane ring composed of interconnected segments and thereby is variable. Each segment has at least one vane, which usually consists of a spatially bent sheet metal part.

Vorteilhafterweise weist jedes Blechteil zwei Schenkel auf, die einen stumpfen Winkel einschließen, von dem der erste Schenkel die Leitschaufel bildet und der zweite Schenkel einen Arm, der zusammen mit dem Arm der benachbarten anderen Leitschaufeln zu einem die Laufradachse umschließenden Ringkörper verbindbar ist.Advantageously, each sheet metal part on two legs, which include an obtuse angle, of which the first leg forms the vane and the second leg a Arm, which is connectable together with the arm of the adjacent other vanes to a wheel axis enclosing ring body.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention can be found in the dependent claims.

Das Laufrad 2 des im einzelnen nicht dargestellten Ventilators eines in Fig. 1 schematisch angedeuteten Luftkühlers 15 sitzt mit seiner Nabe 1 auf der Drehachse 5 eines das Laufrad antreibenden Elektromotors 6. Abstromseitig des Laufrades ist ein stationärer Leitschaufelkranz 3 angeordnet, der von dem Ventilatorlaufrad 2 einen geringen Abstand aufweist und axial mit dem Laufrad fluchtet und dessen Schaufeln 8, wie aus den Figuren 3 - 5 ersichtlich, so gekrümmt sind, dass sie die aus dem Laufrad austretenden Luftstrahlen S bündeln. In Luftströmungsrichtung ist hinter dem Leitschaufelkranz 3, also auf dessen Austrittsseite, ein Berührungsschutz 4 in Form eines Maschendrahtgewebes angeordnet, das wenigstens die Schaufelkanäle abdeckt, um ein Hindurchgreifen und damit eine Berührung des rotierenden Laufrades 2 zu verhindern.The impeller 2 of the fan, not shown in detail in Fig. 1 schematically indicated air cooler 15 is seated with its hub 1 on the axis of rotation 5 of the impeller driving electric motor 6. Downstream of the impeller, a stationary vane ring 3 is arranged, of the fan impeller 2 a has small distance and axially aligned with the impeller and its blades 8, as shown in Figures 3-5 can be seen, are curved so that they bundle the emerging from the impeller air jets S. In the air flow direction, a contact protection 4 in the form of a wire mesh fabric is arranged behind the vane ring 3, ie on its outlet side, which covers at least the blade channels to prevent reaching through and thus contact the rotating impeller 2.

Der sternförmige Leitschaufelkranz 3 ist, wie insbesondere Fig. 2 entnommen werden kann, aus miteinander verbundenen Segmenten 7 zusammengesetzt, wie aus den Figuren 3 und 4 ersichtlich, von denen jedes Segment eine Leitschaufel 8 aufweist, die aus einem räumlich gebogenen Blechteil 9 besteht.The star-shaped vane ring 3, as can be seen in particular in FIG. 2, is composed of interconnected segments 7, as shown in FIGS. 3 and 4 can be seen, each of which segment has a guide blade 8, which consists of a spatially bent sheet metal part 9.

Das Blechteil 9 besitzt zwei Schenkel 10, 11, die einen stumpfen Winkel α von 112,5° einschließen, von denen der erste Schenkel 10 die Leitschaufel 8 bildet und der zweite, abgewinkelte Schenkel 11 einen Arm 12, der zusammen mit dem Arm 12 der benachbarten anderen Leitschaufeln 8 zu einem die Laufradnabe 1 umschließenden Ringkörper 13 verbunden ist, wie aus Fig. 2 ersichtlich. Somit besteht der beispielshalber dargestellte Ringkörper aus acht Segmenten 7 der beschriebenen Art, die identische Bauteile sind. Diese Identität der Blech- bzw. Bauteile ermöglicht eine vereinfachte Herstellung und erhebliche Kostenersparnis bei der Anfertigung derartiger Leiträder, wobei durch eine Änderung des stumpfen Winkels α, in dem die beiden Schenkel 10, 11 des Blechteils 9 zusammenstoßen, auf einfache Weise auch eine Vergrößerung oder Verkleinerung des Leitschaufelkranzdurchmessers bzw. der Anzahl der Leitschaufeln möglich ist.The sheet metal part 9 has two legs 10, 11, which enclose an obtuse angle α of 112.5 °, of which the first leg 10 forms the guide vane 8 and the second, angled leg 11 an arm 12, which together with the arm 12 of the adjacent other vanes 8 is connected to an impeller hub 1 enclosing annular body 13, as shown in FIG. 2. Thus, the annular body shown by way of example consists of eight segments 7 of the type described, which are identical components. This identity of the sheet metal or components allows a simplified production and considerable cost savings in the preparation of such guide vanes, which by a change in the obtuse angle α, in which the two legs 10, 11 of the sheet metal part 9 collide, in a simple way, a magnification or Reduction of the vane diameter or the number of vanes is possible.

Der die Leitschaufel 8 bildende Schenkel 10 des Blechteils 9 bildet im Zusammenbauzustand des Leitschaufelkranzes 3 mit den anderen Blechteilen 9 eine in Strömungsrichtung der Luft verlaufende ebene, senkrechte oder nahezu senkrechte Fläche 14, wie aus Fig. 4 ersichtlich, die im Bereich ihrer unteren Randkante 15 eine Abwinklung 16 hat, welche der in den Leitschaufelkranz vom Laufrad 2 her eintretenden Luftströmung einen gewünschten Drall erteilt, welcher für die Wurfweite des Luftstrahls bestimmend ist. Diese Abwinklung ist in Fig. 4 bei 16 erkennbar und in Fig. 3 als parallel zur Randkante 15 verlaufender Strich angedeutet. Sie hat am Leitradaußenumfang 17 eine rückgeschnittene Kante 18, die zur Aufnahme eines Schutzgitters 4 dient.The leg 8 of the sheet metal part 9 which forms the guide blade 8 forms in the assembled state of the guide blade rim 3 with the other sheet metal parts 9 a flat, vertical or nearly vertical surface 14 extending in the direction of air flow, as can be seen in FIG. 4, which is in the region of its lower edge 15 an angled portion 16, which gives the air flow entering the vane ring from the impeller 2 a desired twist, which determines the throw of the air jet. This bend is visible in Fig. 4 at 16 and indicated in Fig. 3 as parallel to the peripheral edge 15 extending line. It has at the Leitradaußenumfang 17 a recut edge 18, which serves to receive a protective grid 4.

Außerdem weist der zweite Schenkel 11 des Blechteils 9 an seinem äußeren Ende eine Befestigungsabwinkelung 19 auf, mit Hilfe derer die einzelnen Segmente 7 bzw. deren Blechteile 9 zu dem geschlossenen Ring, den der Leitschaufelkranz bildet, zusammengesetzt werden können. Die gegenseitige Befestigung der Blechteile 9 erfolgt dann mittels durch in den Schenkeln 11 vorgesehen Löchern 20, die im Zusammenbauzustand in den aufeinander folgenden Schenkeln 11 der Leitschaufeln 8 deckungsgleich übereinander liegen und von Schrauben durchgriffen werden. Anstelle einer Verschraubung dieser Schenkel ist auch deren Vemietung oder Verschweißung möglich.In addition, the second leg 11 of the sheet metal part 9 at its outer end a Befestigungsabwinkelung 19, by means of which the individual segments 7 and their sheet metal parts 9 to the closed ring, which forms the vane ring, can be assembled. The mutual attachment of the sheet metal parts 9 is then carried out by means provided in the legs 11 holes 20 which are congruent in the assembled state in the successive legs 11 of the vanes 8 and are penetrated by screws. Instead of screwing these legs and their Vemietung or welding is possible.

Die erwähnten Löcher sind in Figur 7 bei 20 dargestellt.The mentioned holes are shown at 20 in FIG.

Die Befestigungsabwinkelung 19 am Schenkel 11 schließt, wie aus Fig. 4 ersichtlich, mit der übrigen Fläche des Schenkels 11 einen stumpfen Winkel von 135° ein, dessen Größe jedoch von der Anzahl der miteinander zu einem geschlossenen Ring verbundenen Blechteile 9 abhängt, die bei dem vorliegenden Ausführungsbeispiel acht beträgt.The Befestigungsabwinkelung 19 on the leg 11 includes, as shown in Fig. 4, with the remaining surface of the leg 11 an obtuse angle of 135 °, the size of which, however, depends on the number of interconnected to a closed ring sheet metal parts 9, in the present embodiment is eight.

Erfindungsgemäß wird somit ein variables Leitrad, auch Nachlaufrad genannt, geschaffen, das infolge seines Zusammenbaus aus identischen Segmenten, die leicht herstellbar sind, mit erheblich geringeren Kosten angefertigt werden kann als die herkömmlichen Leiträder, wobei außerdem die Möglichkeit geboten wird, die Wurfweite des das Leitrad verlassenden Luftstrahls dadurch zu variieren, dass die Abwinkelung der einzelnen Leitschaufeln 8 von Hause aus geändert wird, indem der Biegewinkel, sofern die Segmente 7 aus Blech bestehen, für die Abwinklung geändert wird.According to the invention thus a variable stator, also called Nachlaufrad created, which can be made due to its assembly of identical segments that are easy to produce, with significantly lower costs than the conventional guide wheels, which also offered the opportunity, the throw of the stator leaving air jet vary in that the deflection of the individual vanes 8 is changed from home by the bending angle, if the segments 7 are made of sheet metal, is changed for the bending.
