Description

Die Erfindung betrifft einen Ventilator bestehend aus einem einteiligen Gehäuse aus Kunststoff mit den integrierten Elementen Einlaufdüse, zylindrische Strömungsführung, Diffusor, Nachleitflügeln und dem daran befestigen Motorträger, einem Flügelrad, welches um eine zentrale Achse drehbar gelagert ist, bestehend aus einer zentralen Nabe und daran befestigten Flügeln mit Strömungselementen (Winglets) an den radial äußeren Enden, einem elektrischen Antriebsmotor, der als Außenläufermotor entweder in AC oder EC Technologie ausgeführt ist sowie einem Schutzgitter, das an einer dafür vorgesehenen Vorrichtung des Gehäuses angebracht werden kann.The invention relates to a fan consisting of a one-piece housing made of plastic with the integrated elements inlet nozzle, cylindrical flow guide, diffuser, Nachleitflügeln and attached to the engine mount, an impeller which is rotatably mounted about a central axis, consisting of a central hub and attached thereto Wings with winglets at the radially outer ends, an electric drive motor, which is designed as an external rotor motor in either AC or EC technology and a protective grid, which can be attached to a device provided for this purpose of the housing.

Die WO 2004/094835 A1 beschreibt einen Lüfter mit einem Lüfterförderkanal und darin angeordneten Lüfterrad, welches um eine zentrale Achse drehbar ist und eine zentrale Nabe mit einem Außenumfang aufweist, auf welchem Lüfterflügel befestigt sind, die sich mit ihren radialen Außenkanten bis zu einer nach außen begrenzenden Fläche erstrecken und welche sichelförmige Vorderkanten aufweisen und welche im Bereich des radial äußeren Randes mit Strömungselementen versehen sind, die für eine um diesen radial äußeren Rand von der Druckseite zur Saugseite verlaufende Ausgleichsströmung als Umströmungshindernisse ausgebildet sind.The WO 2004/094835 A1 describes a fan with a fan conveyor channel and fan disposed therein, which is rotatable about a central axis and has a central hub with an outer periphery on which fan blades are fixed, which extend with their radial outer edges to an outwardly limiting surface and which crescent-shaped Have leading edges and which are provided in the region of the radially outer edge with flow elements, which are designed for flow around this radially outer edge from the pressure side to the suction side compensating flow as Umströmungshindernisse.

Im Fan Noise Artikel "EXPERIMENTAL AEROACOUSTIC ANALYSIS OF EFFICIENT AUTOMOTIVE ENGINE COOLING FAN SYSTEM" 2003, ist ein energieeffizienter Lüfter für den Einsatz in Fahrzeugkühlsystemen beschrieben, bestehend aus einem Flügelrad mit Motor eingebaut in einem Gehäuse, welches die funktionellen Elementen zylindrische Strömungsführung, Diffusor und Nachleitflügel in einem Bauteil integriert, wobei hier die kompakte Bauweise des Lüfters hervorgehoben ist.In the Fan Noise article "EXPERIMENTAL AEROACOUSTIC ANALYSIS OF EFFICIENT AUTOMOTIVE ENGINE COOLING FAN SYSTEM" 2003, is an energy-efficient fan for use in vehicle cooling systems described, consisting of an impeller with motor installed in a housing which incorporates the functional elements cylindrical flow guide, diffuser and guide vanes integrated in one component, whereby the compact design of the fan is highlighted here.

Aufgabe der Erfindung ist es einen Ventilator zu offenbaren, der in einer kompakten Bauweise eine weitere Geräuschminderung sowie einen höheren Wirkungsgrad aufweist, wobei ein Schutzgitter gleich mit in den erfindungsgemäßen Ventilator integriert ist.The object of the invention is to disclose a fan, which has in a compact design, a further noise reduction and higher efficiency, with a protective grid is integrated with the same fan in the invention.

Erfindungsgemäß wird diese Aufgabe einerseits dadurch gelöst, dass das einteilig aus Kunststoff bestehende Gehäuse (1) des Ventilators die für die Wirkungsgraderhöhung maßgeblichen Elemente Einlaufdüse (1.1), zylinderförmige Strömungsführung (1.2), Nachleitflügel (1.3) und Diffusor (1.5) in einem kompakten Bauteil integriert, wobei die Nachleitschaufeln gleichzeitig die Anbindung des Motorträgers (1.4) übernehmen, wobei die Verwendung von Außenläufermotoren eine besonders kompakte Bauweise erlaubt. Andererseits, insbesondere hinsichtlich der Geräuschminderung, wird die Aufgabe erfindungsgemäß dadurch gelöst, dass profilierte Flügel (2.2) und Nachleitflügel (1.3) verwendet werden, wobei die radial äußeren Enden (2.3) der Laufradflügel (2.2) mit Strömungselementen (Winglets) versehen sind und wobei der Kopfspalt zwischen Laufradflügel (2.2) und zylinderförmiger Strömungsführung (1.2) besonders klein ausgeführt ist, was erst durch Verwendung spezieller Kunststoffe und Spritzgusstechniken ermöglicht wird.According to the invention, this object is achieved, on the one hand, in that the housing (1) of the fan, which is made of plastic, comprises the inlet nozzle (1.1), cylindrical flow guide (1.2), guide vane (1.3) and diffuser (1.5) which are decisive for increasing the efficiency integrated, wherein the guide vanes simultaneously take over the connection of the motor carrier (1.4), the use of external rotor motors allows a particularly compact design. On the other hand, in particular in terms of noise reduction, the object is achieved in that profiled wing (2.2) and Nachleitflügel (1.3) are used, the radially outer ends (2.3) of the impeller blades (2.2) are provided with flow elements (winglets) and wherein the head gap between impeller blades (2.2) and cylindrical flow guide (1.2) is designed to be particularly small, which is made possible only by using special plastics and injection molding techniques.

Das Gehäuse (1) übernimmt hier mehrere Funktionen gleichzeitig und benötigt dabei vergleichsweise geringen Bauraum. So übernimmt das Gehäuse (1) die Aufhängung des kompletten Flügelrads (2) mit seinem elektrischen Antriebsmotor (5), der als Außenläufermotor ausgebildet ist. Die Übertragung aller am Ventilator angreifenden Kräfte und Momente nach außen geschieht über die mit dem Motorträger und Gehäuse verbundenen Nachleitflügel (1.3). Diese Nachleitflügel (1.3), welche die Umfangskomponente der Abströmgeschwindigkeit reduzieren, tragen mit ihrer speziellen Profilierung wesentlich zur Erhöhung des statischen Wirkungs-grades des Ventilators bei. Die Einlaufdüse (1.1) des Gehäuses hat hierbei die Aufgabe, das Fluid aus dem saugseitigen Raum weitestgehend verlustarm zu beschleunigen und weist hierzu in Strömungsrichtung eine spezielle, sich verengende Kontur auf.The housing (1) takes over several functions at the same time and requires relatively little space. Thus, the housing (1) takes over the suspension of the complete impeller (2) with its electric drive motor (5), which is designed as an external rotor motor. The transmission of all forces and torques acting on the fan to the outside takes place via the guide vanes (1.3) connected to the engine mount and housing. This Nachleitflügel (1.3), which reduce the peripheral component of the outflow velocity, contribute with their special profiling significantly to increase the static efficiency of the fan. The inlet nozzle (1.1) of the housing in this case has the task to accelerate the fluid from the suction-side space largely loss and has this purpose in the flow direction on a special, narrowing contour.

Um die Verluste und die Lärmentstehung, die durch den Spalt zwischen den Flügelblattspitzen (2.3) des Flügelrades (2) und dieser Seitenwand der zylinderförmigen Strömungsführung (1.2) verursacht werden, weiter zu minimieren, wird dieser Spalt sehr klein ausgeführt. Des Weiteren sorgen Strömungselemente (Winglets) (2.3) für eine deutlich reduzierte Geräuschentstehung.In order to further minimize the losses and the generation of noise caused by the gap between the blade tips (2.3) of the impeller (2) and this side wall of the cylindrical flow guide (1.2), this gap is made very small. Furthermore, flow elements (winglets) (2.3) ensure a significantly reduced generation of noise.

Die Strömung gelangt stromab des Flügelrades (2), umgelenkt von den Nachleitflügeln (1.3), in den Diffusor (1.5), also in einen sich erweiternden Strömungskanal. Durch den Diffusor (1.5) wird insbesondere die axiale Komponente der Abströmgeschwindigkeit verringert, was zu einer weiteren Erhöhung des Wirkungsgrades und damit der Leistungsfähigkeit des Ventilators beiträgt. An das Gehäuse (1) ist weiterhin strömungsausgangsseitig ein Schutzgitter (3), welches insbesondere als Maschengitter ausgeführt ist, befestigbar. Ein weiterer Aspekt der Erfindung ist es, dass Außenläufermotoren, entweder in AC oder in EC Technologie, verwendet werden. Dies erlaubt eine besonders kompakte Bauweise, wobei EC-Motoren noch einen zusätzlichen Wirkungsgradvorteil bringen.The flow passes downstream of the impeller (2), deflected by the Nachleitflügeln (1.3), in the diffuser (1.5), ie in a widening flow channel. By the diffuser (1.5) in particular the axial component of the outflow velocity is reduced, which contributes to a further increase in the efficiency and thus the performance of the fan. On the housing (1) is further flow outlet side, a protective grid (3), which is designed in particular as a mesh grid, fastened. Another aspect of the invention is that external rotor motors, either in AC or in EC technology, are used. This allows a particularly compact design, with EC motors still bring an additional efficiency advantage.
