Abstract
Dämpfungsvorrichtung eines Lüftungskanals (2), in welchem ein Ventilator (6) angeordnet ist, dadurch gekennzeichnet, dass in Strömungsrichtung nach dem Ventilator (6) wenigstens ein schallabsorbierender Körper (16, 36) und/oder Flächen und/oder Elemente (26) angeordnet sind, welche strömungstechnisch optimiert sind.damping device a ventilation duct (2), in which a fan (6) is arranged, characterized that in the flow direction the fan (6) at least one sound-absorbing body (16, 36) and / or surfaces and / or elements (26) are arranged, which fluidically are optimized.
Description
Die Erfindung bezieht sich auf eine Dämpfungsvorrichtung eines Lüftungskanals mit einem Ventilator.The The invention relates to a damping device of a ventilation duct with a fan.
Die Dämpfungsvorrichtung zur Schalldämpfung, kurz Schalldämpfer, soll sowohl strömungstechnisch als auch akustisch optimal ausgebildet werden. Ferner soll erreicht werden, dass in Strömungsrichtung hinter dem Ventilator die Strömungsgeschwindigkeit, bevorzugt langsam, abnimmt und der dynamische Druck reduziert wird. Es soll die am oder für den Ventilator benötigte Leistung verringert werden und/oder eine statische Druckerhöhung bzw. ein erhöhter nutzbarer Druck erzeugt werden.The damping device for soundproofing, short silencer, should be both fluidic as well as acoustically optimally trained. Furthermore, should be achieved be that in the flow direction behind the fan the flow velocity, preferably slow, decreases and the dynamic pressure is reduced. It should be on or for needed the fan Performance can be reduced and / or a static pressure increase or a increased usable pressure can be generated.
Im Lüftungskanal sind in Strömungsrichtung nach dem Ventilator schallabsorbierende Körper und/oder Flächen und/oder Elemente angeordnet, und zwar insbesondere an der Außenseite eines zentralen Körpers, welcher strömungstechnisch optimiert ist und insbesondere kegelförmig ausgebildet ist und in dem den Ventilator nachgeordneten Diffusor vorgesehen ist. Zusätzlich oder alternativ können im Rahmen der Erfindung an der Innenfläche des Lüftungskanals hinter dem Ventilator, bevorzugt als Kulissen ausgebildete Körper zur Schallabsorption angeordnet sein. Erfindungsgemäß sind im Lüftungskanal, und zwar in Strömungsrichtung nach dem Ventilator ein oder mehrere Körper angeordnet, welche an den vom Luftstrom überstrichenen Flächen schalldämmendes Absorptionsmaterial aufweisen. Die genannten Körper sind derart angeordnet, dass nach dem Ventilator, insbesondere und/oder im wesentlichen in axialer Richtung sich ausbreitende Schallwellen auf das Absorptionsmaterial treffen. Ferner sind die genannten Körper derart ausgebildet und/oder angeordnet, dass die genannten Schallwellen zumindest zum überwiegenden Teil auf das schalldämmende Material auftreffen.in the ventilation duct are in the flow direction the sound-absorbing body and / or surfaces and / or Elements arranged, in particular on the outside a central body, which fluidically is optimized and in particular conical and in the fan downstream diffuser is provided. Additionally or alternatively, in the Frame of the invention on the inner surface of the ventilation duct behind the fan, preferably designed as scenes trained body for sound absorption be. According to the invention are in Ventilation duct, in the flow direction after the fan one or more bodies arranged, which at The swept by the air flow surfaces soundproofing Have absorption material. The said bodies are arranged in such a way that after the fan, in particular and / or substantially in the axial direction propagating sound waves on the absorption material to meet. Furthermore, the said bodies are designed and / or arranged in such a way, that said sound waves, at least for the most part on the sound-absorbing material incident.
Die Erfindung wird nachfolgend anhand der in der Zeichnung dargestellten Ausführungsbeispiele näher erläutert, ohne dass insoweit eine Beschränkung erfolgt.The Invention will now be described with reference to the drawing Embodiments explained in more detail, without that in that respect a restriction he follows.
