Definitions

  • the invention relates to a device for exchanging heat between a fluid and atmospheric air, in particular for cooling the heat engine of a motor vehicle.
  • a device comprising a heat exchanger having two opposite main parallel faces and comprising a bundle of tubes, the tubes of which extend parallel to said faces, opening out at least a fluid box, and further comprising a fan propeller arranged opposite one of the main faces of the exchanger, in line with the bundle of tubes, and which can rotate around an axis perpendicular to said faces, so as to producing a forced air flow through the exchanger, as well as a drive motor for the propeller, the engine and the propeller being fixed to the heat exchanger, the engine being arranged at least partly in outside the perimeter of the tube bundle, as seen in the direction of the axis of the propeller, the motor being connected to the latter by transmission means and its dimension in the direction of the axis of the propeller overlaps t at least in part, to the thickness of the heat exchanger.
  • the engine is supported by a short side of the radiator and more precisely by the short side of the bundle of finned tubes, which requires the use of support devices which prove be complicated and possibly damage the tube bundle, which is generally a fragile part.
  • it is necessary to intervene in a reduced space provided between the propeller carried by the motor and the electric motor to, for example, set up the means transmission between said engine and said propeller, this intervention proving inconvenient given the lack of space.
  • the object of the invention is to remedy the aforementioned drawbacks.
  • the engine located outside the perimeter of the heat exchanger, does not obstruct the air circulation at right of the tube bundle.
  • the weight of the propeller being low compared to that of the engine, the means of fixing the propeller on the exchanger may have reduced dimensions, further increasing the passage section available for air circulation.
  • the superposition of the axial dimension of the motor on the thickness of the tube bundle reduces the size of the device in the direction of the thickness.
  • the entire electric motor, propeller and transmission means form a single unit which is easily transportable and easy to handle.
  • the drive motor is advantageously arranged beyond the fluid box with respect to the beam.
  • the propeller being mounted on a support extending opposite the same face of the heat exchanger as the propeller and itself fixed on the exchanger in the region of the fluid box and in the region opposite to this, the drive motor is mounted on a portion of the support extending in overhang beyond the fluid box.
  • the arrangement according to the invention makes the motor insensitive to this air flow and in particular to the heating thereof. by contact with the tubes.
  • the device illustrated in FIGS. 1 to 3 intended for cooling the coolant of the heat engine of a motor vehicle, comprises a heat exchanger or cooling radiator 1, comprising a bundle of tubes 2 formed from a multiplicity of elongated tubes 3 all parallel each passing through a stack of dissipation fins 4 in the form of thin rectangular plates.
  • the tubes 3 and the fins 4 form a parallelepiped block having two opposite main faces 5 and 6, parallel to the axes of the tubes.
  • the radiator 1 also comprises a fluid box 7 disposed at one end of the tube bundle and provided with a connector 8, or two connectors, for the entry of the coolant into the radiator and / or for the exit from this radiator fluid.
  • the interior of the fluid box communicates with all of the tubes 3 so as to allow the circulation of the cooling fluid along each of them, from or to the fluid box.
  • the tubes can be connected to another fluid box, or be connected in pairs in a U shape.
  • the fluid box 7 has a boss 9 on which is fixed one end of a sheet metal support 10 having the general shape of a strip extending in the longitudinal direction of the tubes 3 between the boss 9 and a second fixing point not shown located at the end of the exchanger opposite to the fluid box 7, this second attachment point may belong to another fluid box, or to a cross member.
  • the direction of the width of the support 10 is parallel to the faces 5 and 6 of the tube bundle and perpendicular to the axes of the tubes. This width represents only a small fraction of that of the tube bundle.
  • the support 10 In its middle part, the support 10 carries a fixed shaft 11, oriented perpendicular to the faces 5 and 6.
  • a fan propeller 13 On the shaft 11 can rotate the hub 12 of a fan propeller 13, which propeller comprises a multiplicity of blades 14 s' extending radially between the hub 12 and a peripheral ring 15 forming a single piece with these and with a cylindrical intermediate ring 16 having a groove 17 forming a pulley.
  • a transmission belt 18 engages in this groove and in the groove of another pulley 19 secured to the output shaft 20, parallel to the shaft 11, of an electric motor 21.
  • This motor is located at- beyond the body of the fluid box 7 with respect to the tube bundle 2, therefore outside the perimeter of the radiator 1, as seen in the direction of the axis of the shafts 11 and 20, hereinafter called axial direction.
  • a mounting flange 22 secured to the motor housing and extending along a plane perpendicular to the axial direction is applied by fixing screws not shown on a mounting surface formed by a face 23 of a flange 24 molded with the fluid box.
  • reinforcement ribs 25 also molded with the fluid box and extending parallel to the axial direction and to the length of the tubes, are connected to the flange 24.
  • the motor 21 passes through an opening in the flange 24 and extends in the axial direction in both directions beyond the thickness of the radiator 1.
  • the size of the device in the axial direction corresponds substantially to that of the motor alone, without adding, even in part, the thickness of the radiator.
  • the size of the device in the axial direction would correspond at least to that of the engine plus the thickness of the bundle of tubes (that is to say the width of the fins 4) and of the part of the fluid box 7 projecting beyond the face 6 of the bundle of tubes.
  • the diameter of the pulley 17 is greater than that of the pulley 19, so that the propeller 13 rotates more slowly than the motor 21.
  • Figures 4 and 5 illustrate a variant of the device and the same references as in Figures 1 and 2 are used to designate similar elements.
  • the flange 24 and the ribs 25 are removed, the support 10 ′ carrying the propeller not shown is fixed on two bosses 9 ′ of the fluid box 7 ′ and is extended at 10 ⁇ beyond these to support the cantilevered motor. This results in a simplification of the assembly of the motor-fan unit and an improvement in its rigidity.
  • the radiator 101 illustrated diagrammatically in FIGS. 6 and 7 comprises a bundle of tubes 102 similar to the bundle 2 of FIGS. 1 to 5 at the opposite ends of which are arranged two fluid boxes 107 and 107a respectively.
  • a support made of ribbed sheet metal 110 extends from one end to the other of the bundle 102, opposite one of the main faces 105 of the latter, and is fixed by means not shown on the fluid boxes 107 and 107a.
  • This support carries a bearing 130 in which a shaft 131, oriented perpendicular to the face 105, can rotate while being immobilized in translation.
  • the shaft 131 is fitted into the hub 112 of a fan propeller 113.
  • the hub 112 is connected by a radial flange 132 to an intermediate ring 116, a multiplicity of blades 114 extending between the latter and a peripheral ring 115 .
  • the support 110 at its connection with the fluid box 107, also carries an electric motor 121 whose axis of rotation is parallel to the longitudinal direction of the tubes of the bundle 102, and therefore perpendicular to the direction of the shaft 131.
  • the output shaft 120 of the engine extends towards the central region of the radiator 101 to the vicinity of the shaft 131, and its free end is guided in a bearing 133 secured to the bearing 130.
  • a bevel gear 134 integral with the shaft 120 meshes with another bevel gear 135 formed on the edge of the intermediate cylindrical ring 116 of the propeller 113 facing the shaft 120 and opposite the bundle of tubes 102, this ring 116 being connected to the flange 132 on the side facing the bundle 102.
  • the ratio of the diameters of the pinions 134 and 135, like that of the pulleys 19 and 17 of the device of FIGS. 1 to 3, is provided to ensure a rotational speed of the propeller less than cel the engine.
  • the motor 121 extends partly opposite the fluid box 107, and partly opposite the bundle of tubes 102. Unlike the motor 21 of Figures 1 to 5, it hides partly the tube bundle, but to a lesser extent than the prior art coaxial propeller motors. The overall size of the assembly in the direction of the axis of the propeller is also reduced due to the orientation of the motor perpendicular to this axis. This arrangement has, compared to that of FIGS. 1 to 5, the advantage of a space requirement on the surface of the device limited to that of the radiator itself.
  • a second motor 121a mounted on the support 110 opposite the fluid box 107a and in part of the bundle of tubes 102, and disposed symmetrically of the motor 121 relative to the axis of the propeller 113.
  • the output shaft 120a of the motor 121a is coaxial with the output shaft 120 of the motor 121, and also extends to the vicinity of the shaft 131 of the propeller, its free end being guided in a bearing 133a secured to the bearings 130 and 133.
  • a bevel gear 134a secured to the shaft 120a also meshes with the bevel gear 135.
  • the propeller 113 can be driven either by one or the other of the motors 121 and 121a, or by both at the same time. This arrangement makes it possible to rotate the propeller at various speeds of choice, by supplying only one of the motors, and / or by supplying them both in series or in parallel. Furthermore, each of the motors requiring less power than the single motor of the device in FIGS. 6 and 7 can have a smaller diameter, which reduces the size of the device in the direction of the axis of the propeller.
  • the motor or motors of the Figures 6 to 9 can be mounted as desired on the fluid boxes or, independently of the propeller support, or on the latter, as described.
  • the engine or each engine of the devices described can be controlled so as to rotate intermittently and / or at variable speed as a function of the temperature of the coolant, by means of control members including a temperature sensor. arranged in the corresponding fluid box.
  • control members including a temperature sensor. arranged in the corresponding fluid box.
  • the arrangement according to the invention makes it possible to group these control members in the vicinity of the engine, for example in a control box mounted on the fluid box, and to connect them to the engine by one or more short conductors.
