Definitions

  • the invention relates to a radiator fan module of a motor vehicle and to a motor vehicle.
  • the radiator fan module has a radiator frame and a radiator fan.
  • Motor vehicles such as passenger cars, usually have a main drive for propulsion.
  • This usually includes an internal combustion engine.
  • the internal combustion engine When the motor vehicle is to be moved, the internal combustion engine is operated and fuel is burned, with part of the thermal energy released in this way being converted into mechanical energy. However, since not all of the energy released can be converted into mechanical energy, the internal combustion engine heats up, so it is necessary to cool it.
  • a radiator fan module is usually used for this, which includes a radiator frame with a radiator fan connected to it.
  • the radiator frame is connected to a radiator network, which is at least partially covered by the radiator frame.
  • the radiator network in turn has several cooling pipes, within which a coolant is guided, which is then fed to the combustion engine via further pipes, where the coolant is heated.
  • the coolant heated in this way is fed back to the radiator network, which is exposed to a headwind when the motor vehicle is moving.
  • the radiator fan By operating the radiator fan, an additional air flow can be generated, so that cooling is improved.
  • the main drive also increasingly includes an electric motor. However, the electric motor produces relatively little noise when in operation.
  • vehicle warning noise generators are usually used. These emit a noise when the motor vehicle is moving, so that an artificial operating noise of the motor vehicle is provided. This is usually similar to the noise generated when the combustion engine is running. Since the vehicle conversion generator is operated depending on the operating conditions of the motor vehicle and other parameters, it is necessary to have a signaling connection to an on-board computer of the motor vehicle. A bus system is usually used for this, which is why it is necessary for the vehicle warning noise generator to have a corresponding connection. A connection to an on-board network is also required for the power supply. Furthermore, the need for cables is increased, which increases the weight and manufacturing costs of the motor vehicle. It is also necessary for the vehicle warning noise generator to meet certain requirements for safe operation, such as a certain electromagnetic compatibility (EMC). This must be taken into account during design, which also increases development and certification costs.

  • the molding also takes place in one production step with the creation.
  • the line 50 is also molded using the plastic so that it is held securely to the cooler frame 20. Only the ends of the line 50 remain free, namely within the housing 48 or within the electronics housing 34.
  • the line 50 by means of which the noise generator 48 and the first electronics 52 are electrically connected, is thus received by the cooler frame 20, namely embedded in the frame body 24. As a result, the fan wheel 30 can rotate without it getting caught in the line 50.
