Abstract
Description
Die Erfindung betrifft einen Minilüfter. Solche Lüfter werden auch als Klein- oder Kleinstlüfter bezeichnet.The The invention relates to a mini-fan. Such fans are also referred to as small or micro fan.
Zur Luftmessung, z.B. für Klimaanlagen in Kraftfahrzeugen, werden Sensorlüfter verwendet. Diese haben z.B. einen Außendurchmesser von 30 mm, d.h. es handelt sich nach dem technischen Sprachgebrauch um Minilüfter.to Air measurement, e.g. For Air conditioners in motor vehicles, sensor fans are used. These have e.g. an outer diameter of 30 mm, i. It is a matter of technical usage to mini fans.
Derartige Minilüfter dienen auch zur Kühlung von Prozessoren in Computern, zur Gerätekühlung bei kleinen Geräten, etc., und ihre Abmessungen sind sehr klein. Z.B. haben
- • die Lüfter der ebm-papst-Serie 250 Abmessungen von 8 × 25 × 25 mm,
- • die der ebm-papst-Serie 400F Abmessungen von 10 × 40 × 40 mm,
- • die der ebm-papst-Serie 400 von 20 × 40 × 40 mm,
- • und die Lüfter der ebm-papst-Serie 600 von 25 × 60 × 60 mm.
- • the fans of the ebm-papst series 250 dimensions of 8 × 25 × 25 mm,
- • the ebm-papst 400F series dimensions of 10 × 40 × 40 mm,
- • the ebm-papst 400 series of 20 × 40 × 40 mm,
- • and the ebm-papst 600 series fans of 25 × 60 × 60 mm.
Die Leistungsaufnahme solcher Lüfter liegt bei der Serie 250 bei 0,4 ... 0,6 W, bei der Serie 400F bei 0,7 bis 0,9 W, und bei der Serie 400 und 600 bei 0,9 ... 3,4 W. Das Gewicht beträgt z.B. bei der Serie 250 etwa 5 g, bei der Serie 400/400F zwischen 17 und 27 g, und bei der Serie 600 etwa 85 g.The Power consumption of such fans is 0.4 ... 0.6 W for the 250 series and 400F for the 400F series 0.7 to 0.9 W, and for the series 400 and 600 at 0.9 ... 3.4 W. The weight is e.g. 5 g in the 250 series and between 400 / 400F in the 400 series 17 and 27 g, and the series 600 about 85 g.
Bei Lüftern dieser Miniaturgröße, die sehr preiswert sein müssen, ist es wichtig, deren Montage äußerst einfach zu machen, damit bei ihrer Herstellung ein hoher Automatisierungsgrad möglich wird und man eine gleichmäßige Qualität und Geräuscharmut solcher Lüfter erhält.at fans this miniature size, the have to be very cheap, It is important, their installation extremely simple to make, so in their production a high degree of automation possible and you get a consistent quality and low noise such fans receives.
Bei solchen extrem kleinen Lüftern kommt erschwerend hinzu, dass ihre Bauteile, durchaus vergleichbar mit denen eines mechanischen Uhrwerks, sehr zierlich und deshalb wenig robust sind. Die Rotorwelle hat z.B. oft nur die Dicke einer Stricknadel und kann deshalb bei sorglosem Umgang leicht verbogen werden, wodurch der Lüfter unbrauchbar wird. Dasselbe gilt für Polbleche.at such extremely small fans To complicate matters, their components are quite comparable with those of a mechanical movement, very delicate and therefore are not very robust. The rotor shaft has e.g. often just the thickness of one Knitting needle and can therefore easily bent when carefree handling be, causing the fan becomes unusable. The same applies to pole sheets.
Es ist deshalb eine Aufgabe der Erfindung, einen neuen Minilüfter bereit zu stellen.It It is therefore an object of the invention to provide a new mini-fan to deliver.
Nach der Erfindung wird diese Aufgabe gelöst durch den Gegenstand des Anspruchs 1. Dadurch, dass ein Teil des Spulenkörpers als Träger ausgebildet ist, auf dem elektrische Elemente des Motors angeordnet werden können, z.B. Bauelemente, Anschlusselemente oder dergleichen, erhält man eine sehr einfache und kompakte Bauweise, wie sie gerade für Minilüfter von größter Bedeutung ist. Auch ergibt sich der Vorteil einer schwingungsarmen Konstruktion und folglich eines geräuscharmen Laufs bei einem solchen Minilüfter.To the invention, this object is achieved by the subject of the Claim 1. The fact that a part of the bobbin designed as a carrier is on which electrical elements of the motor can be arranged, e.g. Components, connection elements or the like, you get a very simple and compact design, just like for mini fans greatest importance is. Also, there is the advantage of a low-vibration construction and consequently a low-noise Run with such a mini fan.
Weitere Einzelheiten und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus dem im folgenden beschriebenen und in der Zeichnung dargestellten, in keiner Weise als Einschränkung der Erfindung zu verstehenden Ausführungsbeispiel, sowie aus den übrigen Unteransprüchen. Es zeigt:Further Details and advantageous developments of the invention result from the one described below and shown in the drawing, in no way as a limitation The invention to be understood embodiment, and from the other dependent claims.
