Definitions

  • the present invention relates to a cooling fan module, in particular an electrically operated cooling fan module, in particular for motor vehicles, in particular with struts located at the front as viewed in the direction of flow.
  • the cooling system of an internal combustion engine mainly dissipates the heat that is given off to the walls of combustion chambers and cylinders because the combustion process is not ideal. Since temperatures that are too high would damage the engine (tearing off the lubricating film, burning the valves, etc.), the combustion engine must be actively cooled.
  • the coolant is pumped through hoses, pipes and/or ducts through the engine (cylinder head and engine block) and, if necessary, through thermally highly stressed add-on parts of the engine, such as the exhaust gas turbocharger, generator or exhaust gas recirculation cooler.
  • the coolant absorbs thermal energy and dissipates it from the components mentioned above.
  • the heated coolant continues to flow to a radiator.
  • This cooler - formerly often made of brass, today mostly made of aluminum - is usually attached to the front of the vehicle, where a flow of air absorbs thermal energy from the coolant and thus cools it down before it flows back to the engine, which closes the coolant circuit.
  • a cooler fan module is provided in front of the cooler (ie upstream) or after the cooler (ie downstream), seen in the direction of flow, which can be driven mechanically via a belt drive or electrically via an electric motor.
  • the following explanations relate to an electrically driven cooling fan module.
  • a radiator fan module traditionally consists of a fan frame which has a fan wheel recess.
  • a motor mount is arranged in the fan wheel recess and is mechanically connected to the fan frame via struts.
  • the struts can be arranged on the downstream or upstream side of the fan shroud, starting from the air volume flow.
  • a motor in particular an electric motor, is held in the motor mount.
  • a fan wheel is arranged on an output shaft of the electric motor, which fan wheel—driven by the electric motor—rotates in the fan wheel recess. Due to the size of the fan wheel recess, which sometimes takes up 70% of the area of the fan frame, challenges arise in providing the necessary stability for the overall system, in particular without significantly impairing the air conveying properties.
  • JP 2007 040110A discloses a cooling fan module according to the preamble of claim 1, in which an inwardly protruding adapter element for reducing a gap with the fan wheel is detachably provided at a tip of a fan ring delimiting the frame opening.
  • the DE 35 03 220 C1 discloses a radiator frame with a frame ring that is detachably fastened and surrounds a fan wheel driven by an internal combustion engine, locking elements being arranged on the outer circumference of the radiator frame, which are locked into slots on the frame ring side by rotating or moving the frame ring.
  • the present invention is based on the object of specifying an advantageous cooling fan module which is advantageous in particular with regard to its rigidity and/or its air conveying properties and/or with regard to further functions provided. According to the invention, this object is achieved by the subject matter of claim 1 . Preferred developments of the cooling fan module are the subject matter of the dependent claims and the following description.
  • the object is achieved by a cooling fan module according to claim 1.
  • this is particularly advantageous since a favorable rigidity of the cooling fan module can be achieved in this way.
  • the fan frame is reinforced, especially in the area of the fan wheel recess, which in previously known solutions often led to a significant reduction in the overall rigidity of the cooling fan module due to its design as an at least essentially material-free opening.
  • the fan frame has a plastic material, in particular the fan frame is formed from a plastic material and/or the fan frame is produced by means of a plastic injection molding process.
  • plastic components in particular injection-molded plastic components
  • the frame ring delimiting the fan wheel recess can be designed with comparatively thin walls, which leads to a reduction in the probability of blowholes.
  • the intentionally reduced rigidity of the fan frame due to the reduced wall thickness is at least compensated for by the separately formed annular structural element, which is arranged on the frame ring.
  • the solution presented above is particularly advantageous since the separate formation of the ring-shaped structural element can lead to advantageous assembly processes.
  • the separately formed annular structural element is arranged on the shroud ring after the fan wheel has been placed in the fan wheel recess.
  • a cooling fan module has a gap between an edge of the fan wheel lying on the outside in the radial direction and the shroud ring, which has a disadvantageous effect on the air delivery volume per unit of time. For this reason, it is a known measure to design this gap as narrow as possible in order to minimize the gap flow, which will be described in more detail below.
  • the separately formed, ring-shaped structural element according to the invention is advantageous in that a larger gap, which facilitates assembly, can be tolerated between the fan wheel and the fan wheel recess is subsequently reduced to a desired level by the arrangement of the separately formed, ring-shaped structural element after the assembly of the fan wheel in the fan wheel recess.
  • a “radiator fan module” within the meaning of the present invention is in particular an assembly which, seen in the flow direction, is arranged in front of or behind a radiator of a vehicle and which is intended, in particular set up, to generate an air volume flow which passes through or around the radiator extends around the radiator, whereby the air volume flow absorbs thermal energy from the radiator.
  • a "fan shroud" within the meaning of the present invention is in particular a frame in which the fan wheel is held and in turn is preferably arranged, in particular fastened, on or in the vicinity of a cooler.
  • a fan frame within the meaning of the present invention preferably has a plastic material, in particular a plastic compound, and in particular the fan frame is formed from this.
  • the fan shroud has a metal material, for example iron, steel, aluminum, magnesium or the like, in particular is at least partially, in particular at least essentially, in particular completely formed from this.
  • a fan frame can also have more than one fan wheel recess, a motor mount, a motor and a fan wheel.
  • the present invention is suitable for use in radiator fan modules with two or more, in particular two, fan wheels.
  • the fan frame additionally has at least one closable opening, in particular at least one flap, in particular a plurality of them. This is particularly advantageous since further air guidance properties can be realized in this way.
  • a "fan wheel recess" in the sense of the present invention is in particular a material recess within the fan frame.
  • struts extend in the fan wheel recess and mechanically, in particular electrically and/or electronically, connect a motor mount, which is also arranged in the fan wheel recess, to the fan frame.
  • the fan wheel recess is delimited by a frame ring.
  • a "frame ring" within the meaning of the present invention delimits the fan wheel recess in a plane perpendicular to the axis of rotation of the fan wheel, the plane being at least essentially identical to the direction in which the fan frame extends.
  • the shroud ring can either be formed by an edge of the fan wheel recess and/or a have axially expanding cylinder surface, which is preferably formed in one piece with the fan shroud.
  • a "motor mount" within the meaning of the present invention is in particular a device for mechanically fastening the motor to the fan frame, in particular for providing the torque counteracting the fan wheel.
  • the engine mount is an at least substantially annular structure in which the engine is held. This is particularly advantageous since an advantageous flow of cooling air through the motor is not impaired in this way.
  • “Struts” within the meaning of the present invention are in particular bar-shaped or sickle-shaped structures which provide a mechanical connection between the motor mount and the fan frame.
  • the struts can have a teardrop-shaped cross section in order to achieve advantageous aerodynamic and/or acoustic effects.
  • a "motor” within the meaning of the present invention is in particular a machine that performs mechanical work by converting a form of energy, for example thermal/chemical or electrical energy, into kinetic energy, in particular torque.
  • a form of energy for example thermal/chemical or electrical energy
  • kinetic energy in particular torque.
  • the fan frame can be operated at least essentially independently, apart from the supply of energy, that is to say without being supplied with kinetic energy from the outside, for example via a V-belt or toothed belt.
  • An “electric motor” within the meaning of the present invention is an electromechanical converter (electrical machine) that converts electrical power into mechanical power, in particular into torque.
  • the term electric motor within the meaning of the present invention includes, but is not limited to, direct current motors, alternating current motors and three-phase motors or brushed and brushless electric motors or internal rotor and external rotor motors. This is particularly advantageous since electrical energy is a form of energy that is easy to transmit in comparison to mechanical or chemical energy and is used to provide the torque required to drive the fan wheel.
  • a "fan wheel” within the meaning of the present invention is in particular a rotationally symmetrical component which has a hub, in particular a hub pot, which connects the fan wheel to the motor, in particular via a shaft protruding from it, in such a way that the torque generated by the Motor is generated, is at least substantially completely transferred to the fan wheel.
  • the fan wheel has a plurality of blades which are provided, in particular set up, to generate an air volume flow, as soon as the fan wheel starts rotating.
  • the wings are preferably inclined relative to the axis of rotation in an angle range of -90° to +90°.
  • the tips of the vanes lying on the outside in the axial direction are connected to one another via an outer ring of the vane wheel.
  • a “separately formed ring-shaped structural element” within the meaning of the present invention is a component manufactured independently of the fan frame, which is only arranged on the frame ring during assembly.
  • a frame ring within the meaning of the present invention has a material from a group comprising duroplast, thermoplastic, thermoplastic compound, iron, steel, aluminum, magnesium or the like or a mixture thereof.
  • the separately formed ring-shaped structural element is formed at least essentially, in particular completely, from a material from the aforementioned group. This is particularly advantageous because in this way a material that differs from the fan frame can be selected for the separately formed ring-shaped structural element, which allows additional freedom in the mechanical and acoustic configuration of the cooling fan module.
  • the shroud ring has a cylindrical lateral surface, in particular with a normal vector of the cylindrical lateral surface being oriented at least essentially perpendicular to the axis of rotation of the fan wheel.
  • the shroud ring is formed in one piece with the fan shroud. This is particularly advantageous since an economically advantageous manufacturing process can be implemented in this way.
  • the shroud ring extends in the downstream direction away from the fan shroud to a free end. This is particularly advantageous because in this way it is not required for mechanical reasons Material can be saved because the air volume flow usually has a low kinetic energy, so that extensive support structures can be dispensed with.
  • the ring-shaped structural element has a U-shaped cross-sectional geometry in a radial cross-section. This is particularly advantageous since in this way a stable structure is created which is intended, in particular set up, to improve the mechanical rigidity of the cooling fan module, in particular in the area of the fan wheel recess.
  • the ring-shaped structural element surrounds the free end of the frame ring in the radial and/or axial direction and/or is at least partially accommodated in the U-shaped cross-sectional geometry of the ring-shaped structural element.
  • the annular structural element is at least partially slipped over the frame ring with the open side, the frame ring being received at least partially, in particular at least essentially completely, in particular completely, in the at least essentially gap-shaped recess of the annular structural element.
  • the struts are arranged on an upstream side of the fan shroud. This is essential because the arrangement of the struts on the upstream or downstream side of the fan frame, in other words the suction or pressure side of the fan wheel, leads to significantly different flow properties that must be taken into account in the course of the design.
  • the separately formed ring-shaped structural element is arranged on the side of the fan shroud opposite the struts. This is particularly advantageous because in this way the connection points between the fan frame and struts do not have to be taken into account, but rather a body that is at least essentially rotationally symmetrical in the area of the frame ring can preferably be used as a basis.
  • the ring-shaped structural element has at least one fastening means, in particular a fastening flange, which is provided for set up in particular is to hold the ring-shaped structural element on the fan shroud.
  • a fastening flange which is provided for set up in particular is to hold the ring-shaped structural element on the fan shroud.
  • the ring-shaped structural element has, in particular rib-shaped, stiffening means which extend on a surface of the ring-shaped structural element opposite the frame ring, in particular in the radial and/or axial direction.
  • stiffening means are material thickenings that run around in the radial direction on the outside of the separately formed, ring-shaped structural element.
  • a gap is formed between the fan wheel and the shroud ring in the radial direction, with the annular structural element being arranged at least partially within this gap.
  • the annular structural element has a gap cross-section reduction section, in particular formed in one piece with the annular structural element, which extends in a radial cross-section in the direction of the fan wheel, in particular in the direction of an outer ring of the fan wheel, and opposite the adjacent section of the annular Structural element is inclined at an angle ⁇ , the angle ⁇ being spanned in a radial plane in which the axis of rotation also runs and between 30° and 150°, in particular between 60° and 120°, in particular between 75° and 105°, in particular preferably at least substantially 90°.
