Abstract
Description
Technisches Gebiettechnical area
Die Erfindung betrifft einen Kühlventilator mit einem separaten Blindventilator.The The invention relates to a cooling fan with a separate blind fan.
Stand der TechnikState of technology
Beim Axialventilator strömt der Luftstrom in der Axialrichtung. Wenn der Axialventilator mit einem Kühlkörper aus Kühlrippen kombiniert wird, kann der Luftstrom durch den Kühlkörper behindert werden, so daß die Kühlwirkung reduziert wird und das Geräusch erhöht wird.At the Axial fan flows the air flow in the axial direction. When the axial fan with a heat sink cooling fins combined, the air flow through the heat sink can be hindered, so that the cooling effect is reduced and the noise elevated becomes.
Daher wird ein Kühlventilator entwickelt, der mit einem einteilig ausgebildeten Blindventilator versehen ist, wobei der Kühlventilator und der Blindventilator einen gemeinsamen Rahmen haben. Durch die Blindschaufeln wird die Strömungsrichtung des Luftstroms verändert.Therefore becomes a cooling fan designed with a one-piece fan is provided, the cooling fan and the blind fan have a common frame. By the Blanks become the flow direction the air flow changed.
Dieser Kühlventilator mit einem einteiligen Blindventilator ist nur für bestimmte Arbeitsbedingungen geeignet. Zudem muß das Kühlventilator gegen einen neuen ausgewechselt werden, wenn einer der beiden Ventilatoren beschädigt ist.This cooling fan with a one-piece blind fan is only for certain working conditions suitable. In addition, that must cooling fan be replaced with a new if one of the two fans damaged is.
Aus
Bei diesem Kühlventilator ist der Abstand zwischen dem Schaufelrad und den Blindschaufeln zu groß, wodurch die kinetische Energie des Luftstroms reduziert wird. Zudem kann zwischen dem Ventilator und dem Blindventilator ein Spalt vorhanden, durch den die Luft austreten kann, so daß die Luftmenge reduziert wird.at this cooling fan is the distance between the paddle wheel and the dummy blades too large, whereby the kinetic energy of the air flow is reduced. moreover there may be a gap between the fan and the blind fan, through which the air can escape, so that the amount of air is reduced.
Aus diesem Grund hat der Erfinder in Anbetracht der Nachteile herkömmlicher Lösungen, basierend auf langjähriger Erfahrung in diesem Bereich, nach langem Studium, zahlreichen Versuchen und unentwegten Verbesserungen die vorliegende Erfindung entwickelt.Out For this reason, in view of the disadvantages of the present inventor Solutions, based on longtime Experience in this area, after a long study, numerous experiments and unceasing improvements to the present invention.
Aufgabe der ErfindungTask of invention
Der Erfindung liegt die Aufgabe zugrunde, einen Kühlventilator mit einem separaten Blindventilator zu schaffen, der die obengenannten Nachteile der herkömmlichen Lösung überwinden kann.Of the Invention is based on the object, a cooling fan with a separate Blind fan to create the above-mentioned disadvantages of the conventional Overcome solution can.
Diese Aufgabe wird durch den erfindungsgemäßen Kühlventilator mit einem separaten Blindventilator gelöst, der aus einem Ventilator, der einen Rahmen aufweist, der einen Luftkanal, eine Lufteintrittsöffnung, eine Luftaustrittsöffnung und einen Nabensitz besitzt, wobei an dem Nabensitz ein Schaufelrad gelagert ist; und mindestens einem Blindventilator, der an der Seite der Luftaustrittsöffnung des Ventilators angeordnet ist und einen Rahmen aufweist, in dem eine Vielzahl von Blindschaufeln vorgesehen sind, die einer Seite des Rahmens vorstehen und durch die Luftaustrittsöffnung in den Luftkanal des Ventilators ragen, wodurch der Abstand zwischen dem Schaufelrad und den Blindschaufeln verkleinert wird.These Task is by the cooling fan according to the invention with a separate Blind fan solved, that of a fan having a frame having an air channel, an air inlet, an air outlet and a hub seat, wherein at the hub seat a paddle wheel is stored; and at least one blind fan on the side the air outlet opening the fan is arranged and has a frame in which a plurality of dummy blades are provided, one side protrude from the frame and through the air outlet in protrude the air duct of the fan, reducing the distance between the impeller and the dummy blades is reduced.
