Abstract

Hinter einem jeden Lüfter bildet sich naturgemäß ein Freistrahl, welcher sich erst nach einem bestimmten Abstand mit der Umgebungsluft verbindet. Dabei kann es zu großskaligen, niederfrequenten Wirbelformen kommen die beeinträchtigend auf den Lüfter wirken.
Durch die erfindungsgemäße Abströmkontur 12 ,die bevorzugt kronenzackigartig 14 um die Ausblasseite des Lüfters herum angeordnet ist, werden die großskaligen Wirbel in der Scherschicht zerschlagen bzw. deren Entstehung von vornherein verhindert. Die Vorteile hierbei sind im wesentlichen die Stabilisierung des Luftfreistrahls, die Reduktion der großskaligen Wirbel im Randbereich des Luftfreistrahls, die Verminderung der niederfrequenten Anregungsbestandteile, sowie erhebliche Geräuschvorteile.
