Abstract

Eine Ventilator-Anlage umfasst ein Kopfteil (17) mit einer Einlassöffnung, mindestens eine Seite zum Verschließen der Ventilator-Anlage, und eine Auslassöffnung. Ein Windradgebläse ist auf einem Gebläse-Gestell (14) angebracht, wobei das Windradgebläse dem Zwecke dient, Luft durch die Einlassöffnung einzublasen und durch die Auslassöffnung auszustoßen. Mindestens ein Paar Leit-Ablenkplatten (28) erstrecken sich nach innen von einem niedrigeren Ende von mindestens einer Seite zur Auslassöffnung hin, wobei das Paar Leit-Ablenkplatten und das Gebläse-Gestell (14) dazwischen einen Luftstromkanal (20) erzeugen. Der Luftstromkanal schafft eine Einengung des Luftstroms zur Erhöhung des Luftdrucks innerhalb des Luftstromkanals (20). Dadurch wird im Wesentlichen ein Luftstrom in einer Richtung im Luftstromkanal (20) und durch die Auslassöffnung erzeugt. Der Luftstrom hat deshalb eine reduzierte Turbulenz, so dass der Lärm von besagter Ventilator-Anlage abgeschwächt wird.

A fan system comprises a head part (17) with an inlet opening, at least one side for closing the fan system, and an outlet opening. A wind turbine blower is mounted on a blower rack (14), with the blower blower serving the purpose of blowing air through the inlet opening and expelling it through the outlet opening. At least a pair of baffles (28) extend inwardly from a lower end of at least one side toward the outlet opening, the pair of baffles and the fan frame (14) defining an airflow channel (20) therebetween. The airflow channel creates a constriction of the airflow to increase the air pressure within the airflow channel (20). This essentially creates an air flow in one direction in the air flow channel (20) and through the outlet opening. The air flow therefore has a reduced turbulence, so that the noise is attenuated by said fan system.
