Stator for ventilator fan for motor vehicle air conditioning has surface area of stator blades less than thirty percent of surface area of rotor blades

摘要

The fan has a stator (1) to direct the air stream and an electric motor driven fan rotor to create the air flow. The stator is made up of multiple radial blades (9) which receive the air stream from the fan rotor and deflect the air stream. The surface area of the stator blades is less than 30% of the surface area of the rotor blades.
