Definitions

  • the invention relates to a cooling system for a motor vehicle, with a radiator, which is flowed through by coolant, which is used in particular for cooling an internal combustion engine, and is flowed through by a cooling air flow, for example, depending on the speed of the motor vehicle, by a fan , in particular an axial fan, which is arranged between the radiator and the internal combustion engine and having a rotatably driven hub, are fixed to the fan blades, which are arranged in an air passage space which is bounded radially outwardly by a Zargenring with a Zargenring micmesser, wherein the rear edges of the fan blades in the air flow direction are arranged at a distance from an end wall of the internal combustion engine.
  • a fan in particular an axial fan, which is arranged between the radiator and the internal combustion engine and having a rotatably driven hub, are fixed to the fan blades, which are arranged in an air passage space which is bounded radially outwardly by a Zargenring with a Zargenring
  • the object of the invention is a cooling system for a motor vehicle, with a radiator, which is flowed through by coolant, which is used in particular for cooling an internal combustion engine, and is flowed through by a flow of cooling air, which, for example, depending on the speed of the motor vehicle, is influenced by a fan, in particular an axial fan, which is arranged between the radiator and the internal combustion engine and has a rotatably driven hub, are fixed to the fan blades, which are arranged in an air passage space which defines radially outwardly by a Zargenring with a Zargenring devismesser is arranged, wherein the air flow in the rear direction edges of the fan blades at a distance from an end wall of the internal combustion engine are to provide, which provides a high cooling capacity and has a stable fan characteristic.
  • the object is in a cooling system for a motor vehicle, with a radiator, which is flowed through by coolant, which is used in particular for cooling an internal combustion engine, and is flowed through by a cooling air flow, for example, depending on the speed of the motor vehicle, from a Fan, in particular an axial fan, is arranged, which is arranged between the radiator and the internal combustion engine and having a rotatably driven hub, are fixed to the fan blades, which are arranged in an air passage space which is bounded radially outwardly by a Zargenring with a Zargenring micmesser, wherein the air flow in the rear direction edges of the fan blades are arranged at a distance from an end wall of the internal combustion engine, achieved in that the rear edges of the fan blades in the flow direction to the end wall of the internal combustion engine towards the Zargenring a supernatant au f sensible.
  • a preferred embodiment of the cooling system is characterized in that the lateral surface of a cylinder whose circumference is the product of the Zargenring carefullymessers with the number Pi and its height of the sum of the supernatant of the rear edges of the fan blades on the Zargenring and the distance of the rear edges the fan blades to the end wall of the internal combustion engine corresponds to a magnification surface is greater than a circular area, which is bounded by a fan blade inner diameter and a fan blade outer diameter of the fan blades.
  • the invention provides a formulaic relationship between the shape and positioning of the bezel ring to achieve a steeper and thus more stable fan characteristic.
  • cooling system is characterized in that the enlargement area is 20 to 40 percent of the annular area bounded by the fan blade inner diameter and the fan blade outer diameter of the fan blades. In the context of the present invention it has been found that in this range the proportion of pressure recovery is greater than the additional friction loss.
  • a further preferred embodiment of the cooling system is characterized in that the Zargenring has a Zargenring barnmesser, which widens towards the end wall of the internal combustion engine. As a result, the air exiting the fan is delayed and thus converted more dynamically into static pressure.
  • a further preferred embodiment of the cooling system is characterized in that the Zargenring scrmesser continuously widens in the flow direction. As a result, the passage cross-section for the air in the flow direction also extends continuously.
  • FIG. 1 a cooling system is shown schematically in section.
  • the cooling system comprises a radiator 1, through which a coolant flows, which is conducted via coolant lines (not shown) to an internal combustion engine 2, which is also referred to as an engine.
  • the coolant is used inter alia for cooling the engine 2.
  • a fan 8 is arranged, which, in particular when the vehicle is stationary or at a slow speed, serves to maintain a sufficient flow of air through the radiator 1.
  • the fan 8 serves to flow through the engine compartment with a sufficient amount of air.
  • the fan 8 comprises a fan hub 9 which is rotatably driven. Radially outside, several fan blades are attached to the fan hub 9, of which in FIG. 1 only one fan blade 12 is visible.
  • the fan blades have a common trailing edge 13, which is arranged at a distance A to the end wall 4 of the motor 2.
  • the fan blades have a common inner diameter Di and a common outer diameter Da on.
  • the fan blades also have a common depth T.
  • the fan 8 is arranged within a Zargenrings 15, which belongs to a fan cowl, which is also referred to as a fan cowl.
  • the Zargenring 15 has a diameter Dz, which widens towards the engine 2, as indicated by a radius R.
  • the fan 8 is with its trailing edge 13 to the motor 2 out in the axial direction on the Zargenring 15 addition.
  • the corresponding supernatant is in FIG. 1 denoted by U.
  • the inventive design of the Zargenrings 15 with the radius R the escaping air can be delayed and thus converted more dynamically in static pressure. This is achieved in particular by the fact that the cross-sectional areas continuously widen along the flow path.
  • a frame TT ⁇ dz ⁇ ( U + A ) ,
  • the cylinder jacket surface can be increased only by the fact that the Zargenring shortened and pushed forward, or the Zargen trimmesser Dz is increased. Although this leads in a wide range, especially in the weakly throttled range, the fan characteristic to losses in fan performance, but leads in strongly throttled work areas to a steeper characteristic and thus to a more stable behavior.
  • the magnification area should be between 20 percent and 40 percent of the annulus area of the fan A fan , since here the portion of the pressure recovery is greater than the additional friction loss. Due to the more stable fan characteristic, a larger air flow can be guaranteed.
  • FIG. 2 In a Cartesian coordinate diagram the change of the static pressure dp is statically plotted in Pa above the mass flow G of the fan in kg / s.
  • a fan characteristic 21 of a conventional cooling system is in FIG. 2 shown in dashed lines
  • a fan characteristic curve 22 of an inventive Cooling system is in FIG. 2 represented in the form of a solid line.
  • the fan characteristic curve 22 of the cooling system according to the invention runs steeper than the fan characteristic curve 21 of the conventional system.
  • the unstable region can be displaced by the cooling system according to the invention, which leads to a more stable behavior of the cooling system during operation of the motor vehicle.
