Definitions

  • the present invention relates to an air blowing assembly comprising a radial fan with expanded air blowing area.
  • Radial fans also referred to as centrifugal fan, squirrel cage fan or blower
  • Radial fans of the prior art comprise a body, an air inlet and an air blowing port provided on the body and positioned perpendicularly to each other, and a fan wheel positioned on the air inlet in the body, for blowing the air received from the air inlet through the air blowing port.
  • the proportion of the air blowing port length (a) to the body length (b) is considerably low ( Figure 1 ).
  • air blowing area is considerably smaller compared to the lateral cross-section of the body.
  • Said small blowing area causes the air blown by the fan wheel to be compressed and to collide the walls of the blowing port. Compressed air colliding the blowing port walls disrupts homogeneous air flow. Consequently, ventilation performance and noise levels of the radial fan are adversely affected.
  • EP2405144A2 and EP2921712A1 disclose a radial fan whose blowing port length is less than body length.
  • US2002119044A1 discloses a centrifugal blower with partitioned scroll diffuser, comprising multiple flow channels.
  • the proportion of the air blowing area of conventional radial fans to the lateral cross-section of the body is increased by means of a supplementary air blowing apparatus for radial fans, of the present application.
  • the proportion of the air blowing area to the lateral cross-section of the body is increased in the radial fan of the present application.
  • the aim of the present invention is to realize an air blowing assembly which is enabling increasing air blowing area of conventional radial fans.
  • the aim of the present invention is to realize an air blowing assembly comprising a radial fan whose air blowing area is increased with respect to its lateral cross-section.
  • air blowing area of the currently available radial fans are increased by means of a detachable supplementary air blowing apparatus.
  • An air blowing assembly is realized whose air blowing area of the radial fan is increased by means of a supplementary air blowing port. Both embodiments comprise the same inventive concept.
  • the air blowing assembly of the application is comprising a radial fan having a body (2), an air inlet (3) and a main air blowing port (4) provided on the body (2) and positioned perpendicularly to each other, a fan wheel (5) positioned on the air inlet (3) in the body (2), for blowing the air received from the air inlet (3) through at least the air blowing port (4); and comprises at least one flow separator (7) fitted into the main air blowing port (4), enabling directing a part of the air blown by the fan wheel (5) to an air duct (6) by splitting the air; at least one air duct (6) fitted on the opposite surface of the body (2) where the air inlet (3) is not present, enabling the flow separator (7) to split the air blown by the fan wheel (5) and to direct the air thereon (on the air duct (6)); and at least one supplementary air blowing port (8) positioned parallel and next to the main air blowing port (4), connected from one end to the air duct (6) and comprising another (
  • the supplementary air blowing apparatus comprises an air duct (6) connected to the supplementary air blowing port (8), whose portion connected to the flow separator (7) extends from the main air blowing port (4) on which it is to be fitted and bends 180° on the main air blowing port (4) on which it is fitted, then bends 180° centered about the fan wheel (5) and advances on said opposite surface on which it is fitted.
  • the air blowing assembly comprises an air duct (6) connected to the supplementary air blowing port (8), whose portion connected to the flow separator (7) extends from the main air blowing port (4), bends 180° on the main air blowing port (4) on which it is fitted, then bends 180° centered about the fan wheel (5) and advances on said opposite surface on which it is fitted and then bends in an S-shape from the corner of the body (2) where the main air blowing port (4) is disposed and thus becomes aligned with the main air blowing port (4) on which it is fitted.
  • a conventional radial fan (1) with the supplementary air blowing apparatus of the invention fitted thereon can be assembled directly to a seat conforming to conventional radial fans provided in systems where currently available radial fans are used.
  • the supplementary air blowing apparatus may have a detachable structure.

Claims (3)

  1. Eine Luftblasvorrichtung, umfasst: einen Radialventilator mit einem Gehäuse (2), einem Lufteinlass (3) und einer am Gehäuse (2) vorgesehenen Hauptluftblasöffnung (4), wobei der Lufteinlass (3) senkrecht zur Hauptluftblasöffnung positioniert ist (4) und ein Lüfterrad (5), das am Lufteinlass (3) im Gehäuse (2) positioniert ist, um vom Lufteinlass (3) empfangene Luft durch die Hauptluftblasöffnung (4) und eine Zusatzlufteinblasöffnung zu blasen, und eine am Radialventilator montierte Luftblasvorrichtung mit mindestens einem Luftkanal (6), der bei Montage der Zusatzluftblasvorrichtung am Radialventilator auf der gegenüberliegenden Oberfläche des Gehäuses (2) positioniert ist, wo der Lufteinlass ( 3) nicht vorhanden ist; mindestens einen Strömungsabscheider (7), der so in die Hauptluftblasöffnung (4) eingebaut ist, dass ein Teil der vom Lüfterrad (5) in Richtung der Hauptluftblasöffnung (4) geblasenen Luft durch Luftaufteilung zum Luftkanal (6) geleitet wird; und mindestens eine zusätzliche Luftblasöffnung (8), die am Radialventilator parallel und neben der Hauptluftblasöffnung (4) angebracht ist, wobei die zusätzliche Luftblasöffnung (8) an einem Ende mit dem Luftkanal verbunden ist (6) und umfasst ein weiteres Ende zum Abführen der Luft, die sich im Luftkanal (6) befindet. Der Luftkanal (6) ist dadurch gekennzeichnet, dass der mit der Zusatzluft-Einblasöffnung (8) verbundenen Teil mit dem Strömungsabscheider (7) verbunden ist, sich von der Hauptluftblasöffnung erstreckt (4) und sich an der Hauptluftblasöffnung (4) um 180° biegt, an der es angebracht ist. Sie biegt sich dann um 180° zentriert um das Lüfterrad (5), an dem es angebracht ist, und bewegt sich auf der gegenüberliegenden Oberfläche, auf der es angebracht ist, weiter.
  2. Ein Luftblasvorrichtung nach Anspruch 1, umfasst den Luftkanal (6), der mit der Zusatzluftblasöffnung (8) verbunden ist, dessen mit dem Strömungsabscheider (7) verbundener Abschnitt sich von der Hauptluftblasöffnung (4) erstreckt, biegt sich um 180° an der Hauptluftblasöffnung (4), an der es angebracht ist, ab, biegt dann um 180° zentriert um das Lüfterrad (5) und bewegt sich auf der gegenüberliegenden Oberfläche, auf der es angebracht ist, vor und biegt sich dann in einer S-Form in Richtung der Ecke des Gehäuses (2), wo sich die Hauptluftblasöffnung (4) befindet und sich mit der Hauptluftblasöffnung (4) vereint.
  3. Ein Luftblasanordnung nach Anspruch 1 ist dadurch gekennzeichnet, dass die zusätzliche Luftblasvorrichtung eine abnehmbares Aufbau aufweist.
