Definitions

  • the present invention relates to a radiator fan module.
  • Radiator fan modules are used to cool the engine in motor vehicles. Cooler fan modules generally seek to make the radiator fan module as cost effective as possible. Another aspect is the comfort of the vehicle occupants, in particular as regards the minimization of the noise of the radiator fan module.
  • a radiator fan module typically consists of a fan wheel, in which a motor for driving the fan wheel is arranged, and a frame, which has mounting struts for mounting the fan wheel.
  • the fan of a radiator fan module is designed to generate an airflow to dissipate the heat generated by the engine.
  • Cooling fan modules used today have a so-called gap flow in addition to the main flow.
  • the gap flow refers to the flow which forms between the fan and the frame due to the negative pressure and which is swirling due to the rotation of the fan.
  • the swirling gap flow counteracts the main flow, whereby the flow behavior of the radiator fan module is adversely affected. This Friedanströmung sometimes leads to a very high noise, which reduces the comfort of passengers in the operation of the motor vehicle.
  • the DE 10 2008 046 508 A1 describes a fan device for ventilation of an internal combustion engine for a motor vehicle with at least one fan with Lüfterradcharactern for air intake, which connect at least one Lüfterradmantel with a fan hub, with at least one fan shroud in which at least one fan is arranged, wherein between at least one Lüfterradmantelabsacrificing and a fan shroud section
  • the first gap is formed such that it extends at least partially radially with respect to a main air flow direction and in the direction of the centrifugal force occurring during a rotational movement of the fan wheel to minimize at least one air flow.
  • the DE 10 2007 036 304 A1 describes apparatus for cooling a motor, comprising a heat exchanger through which air can pass, a fan arranged in the region of the heat exchanger and a fan hood arranged on the heat exchanger, the fan hood surrounding a flow space between the fan and the heat exchanger and bounded by an outer space, wherein the fan cowl a gap through which air can flow is provided in the region of a radially outer circumference of the fan, through which a gap flow can flow from the flow space into the outer space, the gap flow flowing in a direction deviating radially from the fan axis into the outer space.
  • the WO 2008/124656 A1 describes a ring fan with a fan and a frame.
  • the frame has an annular remindstromleit tiller.
  • the WO 98/37319 A1 describes a fan with a frame and a fan.
  • the FR 2 816 360 A1 describes a fan having a frame and a fan.
  • the frame has a structure through which an air flow outside of the fan wheel can pass.
  • the EP 2 236 788 A1 describes a cooling device for a motor vehicle.
  • the cooling device has an axial fan with a circumferential jacket ring.
  • a stationary arranged guide ring is assigned.
  • the WO 93/05275 A1 and the GB 2 358 677 A also describe radiator fan modules.
  • the EP 1 830 072 A2 describes a fan cowl for a heat exchanger with a Zargenring for receiving an axial fan, wherein the axial fan seen in the air flow direction at least one flow guide is connected upstream.
  • the idea on which the invention is based is to guide the spin-curled return flow in a preferred direction and to de-entrain it by means of a return flow guide device specially provided for this purpose.
  • the remindstromleit directs the return flow equal, so that it is no longer swirling, and mixes this backflow with the Flow, which flows between the inner ring of the scaffoldstromleit Vietnamese and the impeller outer ring.
  • the flow of the main flow remains so even after mixing the mixed with the return flow through the remindstromleit boots, twist-free, so that a twist-free flow on the fan blades hits.
