Definitions

  • the invention relates to a blower arrangement, in particular a burner fan for heating systems, such as from EP 0589300, EP 1022469 or EP 1022470 is known.
  • An object of the present invention is to provide a To create a blower arrangement with which a higher pressure As large a volume flow as possible can be achieved to an even higher To allow flow performance.
  • the idea according to the invention is based on the principle of parallel connection of two single-flow fans to form one double-flow fan.
  • the flow guide housing Through the flow guide housing the air flows of the two individual fans can be brought together be, the outlet opening advantageously or a burner tube which may be arranged thereon free can be designed.
  • Another advantage of the flow guide housing consists in that in principle existing single blowers can be used or mounted on it can, for example as a fan according to the above State of the art. Still can with such known individual fans through the arrangement according to the invention an increased pressure can be achieved with a large volume flow.
  • the overall design is relative simple and inexpensive to implement.
  • the drive motor forming the motor drive arrangement is preferably arranged between the individual fans and drives them simultaneously, so that despite two individual fans only a single drive motor is required. You can the two individual fans are mirror-symmetrical or asymmetrical be arranged to the drive motor.
  • the asymmetrical arrangement enables the use of identical single blowers, which leads to a big cost advantage.
  • the individual fans are expediently used as radial fans trained and parallel to each other on the flow guide housing mounted, the side suction openings preferably point in opposite directions so that the Air sucked in from the two opposite directions can be. This has an advantageous and streamlined effect for the total air intake.
  • the opposing ones open Blow-out openings in one the air flows of the blow-out opening of the flow guide duct supplying the flow guide.
  • this can also be used as Pressure chamber to be designed to the dynamic pressure of the Convert airflow to static pressure if this is desirable.
  • To the fan assembly for a heating burner To be able to use it is a burner tube formed blow pipe at the blow opening of the flow guide housing arranged, this burner tube in can advantageously be designed freely.
  • the flow guide housing is preferably essentially cuboid.
  • the double-flow fan arrangement shown are two radial fans 10, 11 in parallel next to each other on a cuboid Flow guide housing 12 mounted.
  • the two radial fans 10, 11 are, for example, according to the above State of the art designed as a hybrid blower and closer there described, so here is a detailed individual description can be dispensed with.
  • These radial fans 10, 11 is one with a circumference Blade 13 provided pot-like impeller 14 rotatable in a housing 15 mounted, starting from a part-circle curved, directly along the blade ring 13 extending circumferential wall area like a screw in the direction of rotation of the impeller 14 radially to an outlet region 16 extended.
  • a drive motor 17 is arranged between the two housings 15 of the two radial fans 10, 11, a drive motor 17 is arranged, the drives two wheels 14 simultaneously via drive axles 18.
  • the two radial fans 10, 11 are mirror-symmetrical arranged to the drive motor 17 and except for different Drive sides for the impellers 14 are essentially identical built up.
  • Radial fans 10, 11 engage with their outlet areas 16 into the flow guide housing 12. You take action through the rectangular openings 19 shown in FIG. 4 the upper flat side of the flow guide housing 12 therethrough.
  • a burner tube At a Blow-out opening 23 of the flow guide channel 22 at the lower one Flat side of the flow guide housing 12 is a burner tube a blowout pipe 24 arranged in a heating burner, for example flanged, welded or screwed on.
  • the flow guide channel 22 could not be as Pressure chamber be formed and directly to the blow-out opening 23rd to lead.
  • a flow guide wall 25 or 26 is arranged through which the two air flows of the two radial fans 10, 11 um 90 ° redirected and merged.
  • 1 is the flow guide wall 25 in the form of two V-like against each other curved part walls formed while according Fig. 4 in a simpler embodiment, the flow guide wall 26 is designed as a flat burner plate.
  • the housing 15 of the radial fan 10, 11 can also not in that Flow guide housing 12 engage, but flanged to this his. Instead of the flow guide housing 12 engaging outlet areas 16 then occur accordingly similarly shaped flow guide chambers, the corresponding blow openings 20, 21 directed towards each other.
  • flow guide chambers can also be used together with the flow guide channel 22 be designed as an integrated chamber.
  • the second embodiment shown in FIG. 5 in a side view largely corresponds to the first embodiment, so that the same or equivalent components or areas with the same reference numerals and are not described again.
  • a modified flow guide housing 27 On a modified flow guide housing 27 are the two radial fans 10, 11 not mirror-symmetrical to the drive motor arranged in between, but arranged asymmetrically, that is, that Radial fan 10 engages according to the first embodiment through a corresponding opening 19 on the upper flat side of the flow guide housing 27 in this one, while the second Radial blower 11 engages laterally in this, so that a modified opening in the flow guide housing 27 for Inclusion of this radial fan 11 is required, which is essentially over the entire length of the flow guide housing 27 extends.
  • two completely identical radial blowers 10, 11 are used, however a drive motor is required in which the two are drive axes extending in opposite directions must have an opposite direction of rotation. This can achieved for example by a flanged gear become.
  • blow-out pipe 24 or the blow-out opening 23 can be variable be arranged on the flow guide housing 12 or 27, for example also instead of the lower flat side of the same on one end, for example on that of the outlet areas 16 distant end face.
