Abstract
Description
Die Erfindung betrifft einen Lüfter mit einem Lüfterrad und einem Gehäuse, insbesondere einem Gehäuse, in welchem der Motor zum Antreiben des Lüfterrads gehalten ist, der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The The invention relates to a fan with a fan and a housing, in particular a housing, in which the motor is held to drive the fan, the specified in the preamble of claim 1. Art.
Aus dem Stand der Technik sind Lüfter bekannt, bei welchen zwischen dem Lüfterrad und dem Gehäuse, in dem ein elektrischer Motor zum Antreiben des Lüfterrads angeordnet ist, ein Spalt ausgebildet ist. Solche Lüfter sind beispielsweise in Kraftfahrzeugen zur Kühlung eines Kondensators oder zum Kältetransport aus einem Verdampfer einer Klimaanlage eingesetzt.Out the prior art are fans known, in which between the fan and the housing, in an electric motor for driving the fan wheel is arranged Gap is formed. Such fans are for example in motor vehicles for cooling a capacitor or for cold transport used from an evaporator of an air conditioner.
Um den Geräuschpegel des Lüfters niedrig zu halten, darf der Spalt zwischen dem Lüfterrad und dem Gehäuse des elektrischen Motors nicht zu groß sein. Dies hat den Nachteil, dass es bei Schnee-, Feuchtigkeit- oder Wassereintrag zur Eisbildung im Bereich des Spalts kommen kann, wodurch das Lüfterrad im Extremfall insbesondere nicht anlaufen kann.Around the noise level of the fan keep the gap between the fan and the housing of the electric motor should not be too big. This has the disadvantage that snow, moisture or water enters the ice can come in the region of the gap, causing the fan in the extreme case in particular can not start.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Lüfter der eingangs genannten Art zu schaffen, mittels welchem eine Behinderung des Drehens bzw. des Anlaufes des Lüfterrads durch Eisbildung verhindert werden kann.It is therefore an object of the present invention, a fan of to create the aforementioned type, by means of which a disability the rotation or the start of the fan wheel prevented by ice formation can be.
Diese Aufgabe wird erfindungsgemäß durch einen Lüfter mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nichttrivialen Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.These The object is achieved by a Fan solved with the features of claim 1. Advantageous embodiments with functional and non-trivial developments of the invention are specified in the dependent claims.
Ein solcher Lüfter mit einem Lüfterrad und einem Gehäuse, insbesondere einem Gehäuse, in dem ein elektrischer Motor zum Antreiben des Luftrads angeordnet ist, wobei zwischen dem Lüfterrad und dem Gehäuse ein Spalt ausgebildet ist, ist erfindungsgemäß so ausgestaltet, dass das Gehäuse im Bereich des Spalts beheizbar ist. Mit einem Gehäuse, der im Bereich des Spalts zum Lüfterrad beheizbar ist, kann beispielsweise in einem Kraftfahrzeug die Eisbildung während der Fahrt verhindert oder beispielsweise bei abgestelltem Fahrzeug ausgebildetes Eis beseitigt werden. Dadurch kann eine Behinderung des Anlaufes oder des Drehens des Lüfterrads durch Eisbildung vor oder während der Fahrt vermieden werden.One such fans with a fan and a housing, in particular a housing, in which an electric motor for driving the air wheel is arranged is, being between the fan and the housing a gap is formed according to the invention is designed so that the casing is heated in the region of the gap. With a housing that in the area of the gap to the fan can be heated, for example, in a motor vehicle, the formation of ice while prevents the ride or, for example, when the vehicle is parked trained ice are eliminated. This can be a hindrance the start-up or the rotation of the fan by ice formation or while the ride can be avoided.
In einer zweckmäßigen Weiterbildung der Erfindung ist vorgesehen, dass das Gehäuse im Bereich des Spalts mittels eines elektrisch beheizbaren Rings beheizbar ist. Dadurch kann auf technisch einfache Weise das Gehäuse im Bereich des Spalts beheizt werden.In an appropriate training The invention provides that the housing in the region of the gap by means of an electrically heatable ring is heated. This can be up technically simple way the housing be heated in the region of the gap.
In weiterer Ausgestaltung der Erfindung hat es sich darüber hinaus als vorteilhaft gezeigt, wenn ein Steckeranschluss zur Stromversorgung des beheizbaren Rings in dem Gehäuse integriert ist. Dadurch sind aufwendige Anschlüsse und Verkabelungen der Bauteile vermieden.In further embodiment of the invention, it has moreover shown as advantageous when a plug connector for power supply the heated ring in the housing is integrated. As a result, complex connections and wiring of the components avoided.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist es vorgesehen, dass der beheizbare Ring im Gehäuse vertieft angeordnet und durch Verclipsen oder Verschrauben befestigt ist. Dadurch kann verhindert werden, dass sich der Ring beispielsweise bei Betrieb des Lüfterrads von dem Gehäuse trennt bzw. entfernt und an dem Lüfterrad schleifend anliegt.According to one advantageous embodiment of the invention, it is provided that the heated ring in the housing recessed and fastened by clipping or screwing is. As a result, it can be prevented that the ring, for example during operation of the fan separates from the housing or removed and on the fan abraded.
In einer werter bevorzugten Ausführungsform ist es vorgesehen, dass das Gehäuse mindestens bereichsweise aus einem Wärme leitenden Werkstoff gebildet ist. Somit kann der ganze Bereich des Spalts beheizt werden, obwohl beispielsweise nur ein Teil der Oberfläche des Gehäuses im Bereich des Spalts mit Heizelementen versehen ist. In dem Fall, dass zum Beheizen des Gehäuses im Bereich des Spalts ein elektrisch beheizbarer, Wärme leitender Ring eingesetzt wird, kann der Ring beispielsweise lediglich einen Teil der Oberfläche des Gehäuses zwischen dem Gehäuse und dem Lüfterrad überdecken.In a preferred embodiment it is intended that the housing at least partially formed of a heat-conducting material is. Thus, the whole area of the gap can be heated, though For example, only a part of the surface of the housing in the region of the gap is provided with heating elements. In the case that for heating the housing in the region of the gap, an electrically heatable, heat-conducting Ring is used, the ring, for example, only one Part of the surface between the case the housing and cover the fan wheel.
