Abstract
Description
Technisches Gebiettechnical area
Die Erfindung betrifft einen Kühlventilator mit Luftführung, der die Luft auf das Zentrum des Rahmens hinter dem Nabensitz konzentrieren kann.The The invention relates to a cooling fan with air duct, to concentrate the air on the center of the frame behind the hub seat can.
Aus
dem taiwanesichen Patent dieses Erfinders ist eine „Luftführung eines
Kühlventilators" bekannt, wie in
Aufgabe der ErfindungTask of invention
Der Erfindung liegt die Aufgabe zugrunde, die Kühlwirkung des obengenannten Kühlventilators weiterhin zu erhöhen.Of the Invention is based on the object, the cooling effect of the above Cooling fan continues to increase.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kühlventilator aus einem Rahmen und einem Flügelrad besteht, wobei der Rahmen an der Innenseite eine Vielzahl von Luftführungselementen aufweist, die mit einem Luftführungsring verbunden, der über Stege mit dem Nabensitz verbunden ist und eine erste Öffnung und eine zweite Öffnung besitzt, wobei die erste Öffnung größer ist als die zweite Öffnung, damit sich die Luft auf das Zentrum des Rahmens hinter dem Nabensitz konzentriert.These Task is inventively characterized solved, that the cooling fan from a frame and an impeller consists, the frame on the inside a variety of air ducts which has an air guide ring connected, over Webs connected to the hub seat and a first opening and a second opening owns, with the first opening is larger as the second opening, so that the air concentrates on the center of the frame behind the hub seat.
Im folgenden wird die Erfindung anhand der beigefügten Zeichnungen näher erläutert.in the Following, the invention will be explained in more detail with reference to the accompanying drawings.
