Definitions

  • the invention relates to a fan module, in particular for air conditioning units in vehicles, comprising a pressure-increasing spiral, which comprises a first fan on a fan rotor at least partially radially, and an electric motor which drives the fan rotor.
  • the passenger compartment in vehicles is ventilated for air conditioning, to increase comfort and driving safety through a ventilation system to which a heating and / or air conditioning unit is connected.
  • the ventilation system is connected to a fan module, which sucks fresh air from the environment of the vehicle and passes through the heating or air conditioning unit, so as to bring the intake air to the desired temperature.
  • the air flowing through the vehicle interior is usually through ventilation slots, z. B. on the parcel shelf on the wheel arches, out of the vehicle interior.
  • the fan module connected to the ventilation system is usually constructed as a radial compressor, which is driven by an electric motor.
  • the electric motor is integrated in its design in the fan module.
  • air is diverted from the already compressed air flow for the vehicle interior for cooling purposes.
  • This has the disadvantage that the operating point but also the efficiency of the fan module is adversely affected.
  • the electric motor and its temperature-critical components does not receive sufficient cooling air. Under the overblowing of the Bläsemoduls is understood when the producible by the fan module pressure is less than the pressure difference between the inlet and outlet of the fan module.
  • This operating state occurs when the vehicle is being moved at high speed and / or the vehicle windows are widely opened. If the vehicle is moved at a high speed, the pressure at the inlet of the fan module is increased by the high driving speed. Opening the vehicle windows results in a reduction in pressure in the vehicle interior. This has the consequence that the pressure difference applied to the inlet and outlet of the fan module is increased and the fan module is in an overblown state, provided that the pressure difference is greater than the pressure generated by the fan module.
  • the overblown state has the consequence for the fan module that the electric motor contains only a reduced proportion of cooling air flow despite increased stress. This leads to overheating of the temperature-critical components of the electric motor.
  • Components of the electric motor of a fan module can be avoided by the fan module has a suction unit, which is designed to promote cooling air into the electric motor.
  • the suction unit of the fan motor has a second fan wheel, which is designed to form a cooling circuit, which conveys cooling air from the pressure-increasing coil through the electric motor through the pressure-increasing spiral.
  • the suction unit is designed by means of the second fan to suck the cooling air through a gap between the fan motor and the pressure-increasing spiral via the fan interior located below the fan motor on the coils and the magnets of the electric motor to the second fan wheel.
  • a guide geometry above the second fan wheel is arranged to redirect the flow of cooling air above the second ventilation wheel in such a way that the flow of cooling air through the first fan wheel is guided radially outward back into the pressure increase spiral. In this way, no compressed air is discharged from the pressure-increasing spiral, so that the fan module can be interpreted at its maximum capacity and therefore requires less space than a fan module, in which the cooling air is diverted from the conveyed air.
  • the first fan, the second fan and the fan rotor is made in one piece. This has the advantage that the first fan, the second fan and the fan rotor in a manufacturing step z. B. can be produced by injection molding.

  • the fan motor 9 sucks air from the upper side of the housing 10 into the fan module 13 with the aid of the first fan wheel 14. Due to the rotation of the air flow is led to the outside and accelerated radially.

  • the electric motor needs a cooling at its temperature-critical elements such as the coils or the magnets. This is achieved in that an air flow from the pressure-increasing spiral 1 is guided via a first gap 23 into the fan interior 2 sitting below the fan rotor 9.

  • a reliable cooling of the magnets 6 and the coils 7 is ensured by the suction of cooling air from the pressure increasing spiral 1 in the overblown state.
