Definitions

  • the invention relates to a fan for a motor vehicle, especially for the cooling of the drive motor, comprising a stator and a rotor capable of rotating relative to to the stator around an axis in order to produce an air flow in the direction of said axis, the rotor and the stator having respectively blades and guide vanes which extend substantially radially in said air flow, the guide vanes being located downstream of the blades by compared to this one.
  • the rotor or propeller of an axial fan produces a movement substantially helical air, and the guide vanes have the function of straightening this movement for the make it parallel to the axis and thus improve the yield aerodynamics of the fan.
  • the guide vanes used so far in fans automobiles had an axial length, i.e. a dimension in the direction of the axis of rotation of the rotor, of the order of 20 mm, which was considered to be sufficient to ensure effective recovery of the flow of air.
  • axial length i.e. a dimension in the direction of the axis of rotation of the rotor, of the order of 20 mm, which was considered to be sufficient to ensure effective recovery of the flow of air.
  • new means of analysis have revealed that was nothing, and that the known blades left a significant circumferential component of the movement of the air flow.
  • the object of the invention is to optimize the characteristics geometry of the guide vanes so as to obtain a practically perfect recovery of the air flow.
  • the invention relates in particular to a fan of the kind defined in introduction, and provides that the axial length of the blades guidelines is at least equal to 40 mm.
  • Figure 1 is a perspective view of a fan according the invention.
  • Figure 2 is a partial view of the stator according to a radial direction, showing the flattened cross section of a directing dawn.
  • the fan shown in Figure 1 for the vehicle drive motor cooling automotive, includes a stator 1 and a rotor 2.
  • the rotor 2 has a bowl-shaped hub 3 having a wall cylindrical of revolution 4, from which blades propeller 5 extend substantially radially outward, and a curved bottom 6.
  • a cylindrical wall of revolution 7, preferably of the same diameter as the wall 4, is located axially opposite it, opposite the bottom 6, and forms a central core for stator 1, from from which guide vanes 8 extend substantially radially outward, substantially on the same radial height than the blades 5.
  • the core 7 and the hub 3 are respectively secured to the stator and the rotor of a electric motor housed inside the core and the hub.
  • the radially outer ends of the vanes 8 can be mutually connected by a ring annular peripheral not shown, the latter can also, like the core 7, be formed of a single piece with the blades, in particular by molding of material plastic or a magnesium-based material.
  • FIG. 2 partially shows the core 7 of the stator, in projection in a radial direction, as well as the section flattened transverse of a guide vane 8, that is to say the closed plane curve obtained by cutting the dawn by a surface cylindrical of revolution around the axis of the fan, and by unwinding flat this cylindrical surface in the plane of the figure.
  • This flattened cross section has a airplane wing profile, the rope 10 of which is inclined by acute angle ⁇ relative to a radial plane such as that containing the downstream end 11 of the stator.
  • the invention provides that the angle ⁇ , or setting angle, is between 25 and 35 °, and decreases gradually when the cross section moves away from the axis, at least over the last 30% of the radial extent of dawn.
  • Figure 2 also shows the axial length L of dawn 8, which according to the invention is advantageously understood between 40 and 60 mm.
