Definitions

  • the invention relates to a radiator fan of a motor vehicle, in particular main fan, with an electric motor.
  • a liquid coolant is usually used, which in turn must be cooled. This is usually done by means of an acted upon by a wind radiator network, which is in heat exchange with the coolant.
  • the coolant is directed into tubes that are incorporated into the radiator network. Since, especially at low vehicle speeds, the airstream for cooling is normally insufficient, it is known, for example, from EP 1 621 773 A1 to use an electric fan by means of which the airstream is amplified.
  • the fan is arranged in the direction of travel behind the radiator network. With the help of a fan of the fan, the air is sucked through the radiator network and passed to the engine. If, in addition to the radiator network, a condenser network of a condenser of an air conditioning system is present, the condenser network is usually arranged upstream of the radiator network in the direction of travel.
  • the electric motor itself is cooled by means of cooling air which is sucked into the electric motor on the side facing away from the radiator network through openings. This cooling air flow is, after the electric motor has flowed through completely, deflected by the hub of the fan and fed to the ambient air.
  • the invention has for its object to provide an improved radiator fan of a motor vehicle and an electric motor, which is particularly comparatively efficiently cooled.
  • the radiator fan is part of a motor vehicle and is used in particular for cooling an internal combustion engine.
  • wind is passed through a radiator network, wherein the wind is amplified by means of the radiator fan or generated at a standstill of the vehicle.
  • the radiator fan includes a fan with a number of fan blades.
  • the fan blades are connected to a central hub. The connection can be made by means of additional elements, such as screws, or material.
  • the fan is made of a plastic and is manufactured in one piece in an injection molding process.
  • the fan wheel is rotated by means of an electric motor.
  • the fan is connected via the central hub to a rotor of the motor.
  • the electric motor is a brushless inner rotor and thus the rotor is arranged within a stator of the electric motor.
  • cooling air directed which is preferably taken from the environment.
  • the steering of the cooling air takes place here at least partially by means of two air ducts.
  • the two air ducts are at least partially sealed against each other, so that cooling air, which is guided in one of the two air ducts, does not come into contact with the cooling air, which is guided in the other air duct.
  • a mixing is preferably carried out only outside the electric motor.
  • the seal is present in the region of the exit from the electric motor, and suitably the seal pneumatically, so that different air pressures in the two air ducts can be realized.
  • one of the air ducts is used to cool the one or more electromagnets of the electric motor, whereas the other is used to cool any existing in the electric motor permanent magnet.
  • a stator of the electric motor and by means of the guided in the other cooling air of the rotor of the electric motor is cooled by means of the guided in one of the air ducts cooling air.
  • one surface of a component of the electric motor is acted upon, whereas the other air duct leads through this component. In this way, the component is cooled both from the outside and from the inside.
  • one of the two air ducts surrounds the other air duct at least partially radially, ie in a radial direction relative to the rotor of the electric motor. Consequently, the distance of the one of the two air ducts to the axis of rotation of the rotor is greater than the corresponding distance of the other air duct.
  • each of the two air ducts is, for example, substantially circular-segment-shaped.
  • the radially outer air duct surrounds the radially inner air duct substantially completely.
  • efficient cooling of both a radially inner region of the electric motor and a radially outer region of the electric motor is ensured.
  • the cross section of the air ducts is substantially annular, perpendicular to the axis of rotation of the electric motor, wherein alternatively, the cross section of the inner air duct is circular.
  • the two air ducts abut each other, and are separated from each other only by means of the seal. At least the distance between the two air ducts is comparatively small.
  • the Rings or the ring and the circle concentric with each other, wherein the center is located in particular on the axis of rotation.
  • the cooling air which is guided in the radially inner air duct, in the region of the outlet is substantially parallel to the direction of entry of the cooling air into the electric motor.
  • the cooling air is sucked through by the electric motor from the side facing away from the radiator network through the electric motor, so that the exiting from the inner air duct cooling air is directed in the direction of the radiator network. This is especially contrary to the direction of any existing wind.
  • the hub has at least one opening into which the radially inner air duct opens.
  • the opening is offset radially inwards.
  • the distance of the opening to the axis of rotation of the electric motor is less than, for example, half the radius of the hub.
  • the distance is equal to or less than a quarter of the radius.
  • a number of openings, so at least two openings, introduced into the hub is relatively hindered, which ensures a rapid passage of the cooling air through the electric motor.
  • using a number of apertures instead of a single large aperture increases the stability of the hub and at least partially inhibits the ingress of dirt into the electric motor.
  • the outlet direction of the cooling air guided in the radially outer air duct is preferably equal to the travel wind direction, that is to say the direction of the airstream, by means of which the electric motor is at least partially acted upon. In this way, a turbulence in the mixing of the exiting cooling air is reduced with the existing wind, which improves the acoustic properties of the radiator fan.
  • the outlet direction is opposite to the direction of entry of the cooling air into the electric motor. If in the radially inner Air duct guided cooling air is led out in the inlet direction of the electric motor, thus a mixing of the cooling air outside the electric motor is comparatively small, so that the heated cooling air is cooled separately and any outside of the electric motor located component of the motor vehicle, which is located in the inlet direction behind the electric motor , Not by means of a comparatively hot and strong flow of cooling air - namely the cooling air from both air ducts - is acted upon.

  • a deflection contour is formed within the hub, by means of which the cooling air is deflected in such a way that it is parallel to the travel wind direction or counter to the direction of entry.
  • the direction of entry of the cooling air into the electric motor is substantially parallel to the axis of rotation of the electric motor. In this way, no space in the region of the magnet structure of the electric motor must be provided for supplying the cooling air, which could hinder the propagation and interaction of the magnetic fields and thus reduce the efficiency of the electric motor.
  • the electric motor comprises a deflection device, by means of which the cooling air is assigned to the corresponding air duct.
  • the deflection is within the electric motor.
  • the deflecting device is consequently enclosed by a possibly present housing of the electric motor.
  • the deflection device is located between the rotor and any existing electronics of the electric motor.
  • the electrical nik is charged by the full cooling air, which is then divided on the two air ducts.
  • the cooling of the electronics is relatively efficient, which is the most temperature-critical component of the electric motor.
  • the air is passed through a suction port or a plurality of pneumatically interconnected inlet openings in the electric motor and in particular sucked.
  • each of the air ducts is filled with cooling air, resulting in spite of the reduced supply of cooling air to an efficient cooling of the electric motor.
  • the deflection device itself is not affected due to the placement within the electric motor of any dirt, which is held in particular by means of a suitable design of the openings outside the electric motor.
  • the deflection device is designed such that the division of the cooling air takes place on the respective air duct according to the desired cooling capacity.

  • the air ducts are substantially rectilinear in this area, which contributes to an increased cooling air velocity and thus enhances the cooling of the electric motor.
  • both air ducts are formed by means of recesses which pass through the rotor.
  • only one of the air ducts is realized by means of a suitable design of the rotor, so that this air duct leads through the rotor.
  • the remaining of the two air ducts is formed in the region of the rotor by means of the provided between the rotor and the stator air gap. In this way, a design effort is reduced and an existing electric motor can be adjusted by introducing the second air duct into the rotor and its seal against the air gap formed between the rotor and stator.
  • the electric motor has two at least partially mutually sealed air ducts into which cooling air is passed during operation of the electric motor.
  • the air ducts lead at least partially through the electric motor and are in particular pneumatically separated from each other, so that cooling air, which is located in one of the two air ducts, can not get into the other of the two air ducts, even with a prevailing pressure difference between the two.
