Definitions

  • the invention relates to a side channel blower according to the preamble of claim 1.
  • Such a side channel blower is in the case of interference elements on the gas outlet side from PATENT ABSTRACTS OF JAPAN, vol. 6, no.50 (M-120) (928) April 3, 1985.
  • the noise development in heaters that are provided with a fan for supplying combustion air to the combustion chamber of the heater is largely determined by flow noises resulting from the combustion air flow in the fan.
  • this noise development proves to be disruptive because of the additional heating device which is usually located in the vicinity of the vehicle occupants due to the limited vehicle dimensions.
  • the object of the invention is therefore to create a device which enables the operation of a blower with reduced noise.
  • the device according to the invention has, at least in the region of the opening cross section of the gas outlet channel and / or the gas inlet channel, an interfering device which influences the flow behavior of the gas flow accelerated by the gas propulsion device.
  • the acceleration of the gas flow induces pressure waves in the fan, in particular in the area of the opening cross section of the gas outlet channel and the gas inlet channel, the propagation of which leads to the known, disadvantageous noise development in the fan.
  • the disturbance device induces flow resistances in the accelerated gas flow, which have an adverse effect on the pressure wave propagation. In this way, the generation of large pressure waves, which lead to a corresponding increase in the noise level during operation of the fan, is prevented.
  • Side channel blowers usually consist of at least two housing parts, between which an impeller is arranged. Both the gas inlet through the gas inlet channel and the gas outlet through the gas outlet channel take place on one side of the impeller, the gas flowing in a channel which is guided parallel to the plane of rotation of the gas propulsion device.
  • the arrangement of the interference device in the edge region of the surface of the interrupter, which faces the impeller, has proven to be particularly effective for reducing the noise, since this surface is located directly adjacent to the impeller and therefore the maximum gas velocities in this region, induced by the impeller, occur.
  • the interfering elements can have a greater extent parallel to said surface than perpendicular to it. This enables a further improvement in the interference effect.
  • Interference elements designed as material recesses can consist of notches with an approximately V-shaped cross section.
  • the notch-shaped design of the interfering elements can be implemented, for example by file blows introduced into the blower housing after the casting process represents a particularly simple possibility of realizing interfering elements.
  • Interfering elements formed from material recesses also offer the advantage that their manufacture already during the manufacture of the blower housing which is generally produced by the casting process, for example by inserting appropriate ones Molded parts can be made in the mold.
  • FIG. 1 shows a housing part 10 of a side channel blower 11 with a side channel 12 formed therein, as well as a gas inlet channel 13 and a gas outlet channel 14.
  • the impeller 15 serves as a gas propulsion device, by means of which gas sucked in through the gas inlet duct 13 is accelerated in the side duct 12 and is output through the gas outlet duct 14.
  • the gas outlet channel 14 With this heater or the combustion chamber is connected to the heater.
  • a suction line (not shown here) can be connected to the gas inlet channel 13.
  • An interrupter 25 separates the inlet-side and the outlet-side end of the side channel 12 from one another.
  • the interrupter 25 has a surface 17 facing the impeller 15, which lies in the plane of the housing separating surface.
  • the interference devices 20, 21 shown by way of example in terms of their arrangement and configuration in FIG. 1 each have individual interference elements 22, 23, each of which is designed as a notch with a V-shaped cross section ( FIG. 2 ).
  • Fig. 2 shows the view in Fig. 1 pivoted by 90 ° the V-shaped cross section of the interference elements 22, wherein it can be seen that the greatest cross-sectional depth of the interference elements 22 lies in a plane perpendicular to the surface 17 and the cross-sectional depth with increasing expansion of the interference elements 22 in the surface 17 decreases steadily, that is, the notches run out slowly.
  • the directional interference effect of the interference elements 22 is generated by the design of the notches inclined in the surface 17 and tapering in this area.
  • the interfering elements 22 and 23 of the interfering devices 20, 21 are arranged approximately in a radial manner around the opening cross sections 18, 19 of the gas inlet channel 13 and the gas outlet channel 14. It is also possible that the individual interference elements 22 and 23 of the interference device 20 and 21 are aligned substantially parallel to each other. Contrary to the illustration in FIG. 1 , the interference elements 22 and 23 can of course also be of the same size. Furthermore, it can prove to be advantageous to arrange disruptive elements 22, 23 not only in the area of the opening cross sections 18, 19 or in the area of one of these two opening cross sections, but disruptive elements 22, 23 individually or in groups distributed over the entire edge area of the area 17 from the opening cross section 18 to provide the opening cross-section 19.
  • the interfering elements 22, 23 do not necessarily have to be limited to the area of the surface 17, but instead or additionally or directly at the opening cross section 18 or 19 of the gas inlet channel 13 or the gas outlet channel 14 or on the inside on the outer peripheral edge 24 of the side channel 12 be arranged.
