Definitions

  • the invention relates to a device for cooling the heat transfer fluid of a heat engine comprising a radiator fixed to a chassis, for example of a motor vehicle, and at least one fan motor comprising an electric motor and a propeller fixed to the shaft of the electric motor.
  • the electric motor was generally fixed with the propeller fixed on its shaft, to a fixing frame comprising support arms and integral with a fixed part integral itself with the bodywork or chassis of the motor vehicle so as to constitute a fan.
  • This fixing frame occupies a significant thickness along the longitudinal axis of the vehicle, which adds to the necessary functional clearance, to be left with the nearest fixed member.
  • the invention proposes to eliminate these drawbacks without reducing the cooling efficiency.
  • the subject of the invention is a device for cooling the heat transfer fluid of a heat engine comprising a radiator fixed to a chassis, for example of a motor vehicle, and at least one fan motor comprising an electric motor and a propeller, the hub consists of a bowl, the edge of which surrounds part of the electric motor, said propeller being fixed on the shaft of the electric motor, characterized in that the electric motor is fixed directly to the radiator by means of fixing means located in line with the projection of the master torque of the bowl of the propeller and in that the edge of the bowl surrounds the part of the electric motor and the part of the fixing means projecting from the radiator.
  • the invention also relates to a device of the aforementioned type, characterized in that the radiator comprises as many housings as motor fans, adapted to receive a corresponding electric motor.
  • the radiator has a shape such that it approximately covers the angular sector described by the blades of the fan (s).
  • Fig. 1 is a top view of a first embodiment in which a fan motor is fixed directly to a honeycomb radiator 1.
  • the cooling device has been shown by way of example in front of an internal combustion engine 2 parallel to the front face of the latter and therefore perpendicular to an axis ⁇ A ', corresponding in the case of a motor vehicle, to the direction of travel.
  • the fan motor 4 comprises an electric motor 5, the shaft 6 of which extends in a direction opposite to the radiator along the axis AA ', and a propeller 7.
  • the propeller 7 consists of a circular bowl, the bottom 8 of which is fixed at its center to the shaft 6 and whose edge 9 extends towards the radiator around the electric motor and carries the blades 10 on its periphery.
  • the electric motor 5 has several fixing lugs 11 arranged at the periphery of its face opposite its shaft 6. Tie rods 12, one end of which is threaded, pass through cells formed by the cooling surfaces and fixing lugs and nuts 13 are tightened on the threaded ends, so that the electric motor is fixed to the front face of the radiator without contact with this face outside the fixing lugs 11.
  • fixing means for example studs, welded to the circulation channels of the heat transfer fluid.
  • a plate 14 has been placed against the rear face of the radiator, so that the tie rods 12 passing through it, the clamping force is applied to this plate and not directly to the cells.
  • This plate 14 may have the shape of a crown, a disc or the like.
  • This plate has the function of reducing the unit compression on the beam dimpled, due to the fastening of the fixing means and, when it is made of elastic or soft material, of damping the vibrations generated by a possible lack of balance of the fan motor 4.
  • the bowl of the propeller has a diameter such that it surrounds this engine as well as the fixing means protruding from the front face of the radiator.
  • the efficiency of the fan is practically not reduced by the fact that the engine masks part of the radiator, since the zones located axially on either side of the central part devoid of propeller blades 7 , formed by the bowl thereof, are practically not traversed by the air flow A generated by the rotating propeller.
  • the corresponding area of the radiator therefore practically does not participate in the heat exchange.
  • the fan motor can of course be placed upstream or downstream of the radiator relative to the direction of movement of the vehicle.
  • FIGS. 2A and 2B show a cooling device according to the invention in which a special non-standard radiator is used.
  • the cooling device 15 is placed upstream of an engine (not shown) relative to the direction of movement.
  • the cooling device 15 comprises a radiator 16, perpendicular to the axis ⁇ ⁇ ′ of the motor vehicle, on one face of which is fixed a fan motor 17 consisting of an electric motor 18 whose shaft 19 is directed opposite the radiator and a propeller 20 whose bowl is fixed by its bottom 21 to the shaft 19, the edge 22 of the bowl carrying blades 23.
  • a housing 24 is provided in the radiator 16 opposite the master torque of the bowl 21, 22 of the propeller 20.
  • This housing has a diameter greater than that of the electric motor 18, so that the latter is introduced partially along its axis longitudinal and along the axis AA 'and fixed on the periphery of the housing 24 formed for example by a central manifold 25 of the circulation channels of the heat transfer fluid.
  • fixing lugs 26 provided on the periphery of the motor 18, are crossed by studs 27 fixed on the periphery of the housing on the opposite face of the propeller 20. Nuts 28 are tightened against the lugs on the threaded ends of studs 27.
  • the studs can also be fixed on opening flow channels to form the housing 24.
  • the bowl of the propeller has a diameter such that its edge 22 surrounds the part of the electric motor projecting from the housing and the means for fixing this motor.
  • Such a device has the same advantages as the device of FIG. 1 and the axial size of the fan is reduced to the width of the edge 22 of the bowl of the propeller, that is to say practically to the width of the blades 23.
  • Fig. 3 shows a schematic front view of a cooling device 30 comprising a radiator 31 on which are fixed two motor fans 32 in order to evacuate a greater number of calories as is sometimes necessary for diesel engines with turbocharger and for vehicles with air conditioning devices.
  • These two fan motors each include an electric motor 33, fixed to the radiator according to the mode of FIG. 1 or of FIG. 2A, and a propeller 34, fixed to the shaft of the electric motor.
  • the radiator has the form of two thick discs or cylindrical parts 35 joined by a throttled part 36 of the same thickness.
  • Such a shape is particularly advantageous because it allows a significant gain in material and weight compared to a conventional rectangular radiator 37 shown in broken lines.
  • the discs 35 have approximately the same diameter as the master torque of each propeller 34, the areas removed with respect to a rectangular radiator practically not participating in the heat exchange.
  • a radiator therefore has an efficiency substantially identical to that of a rectangular radiator within the perimeter of which it fits. It goes without saying that such a radiator can be designed for a single fan. It would then have the shape of a thick disc.
