Definitions

  • the invention relates to a cooling device for the internal combustion engine Motor vehicle, consisting of a cooling fan, a cooler package and a fan frame, that from a fan ring surrounding the cooling fan to the cooler package extends, the cooler package projecting the cooling fan laterally and the projection of the cooling fan projects above and / or below the cooler package.
  • Such a cooling device is approximately in DE-OS 24 39 033, or also in DE-OS 34 04 887.
  • the fan is like in vehicles with a longitudinal engine commonly used, driven by a V-belt. He sweeps a circular area their altitude is mostly unfavorable due to the drive and only within narrow limits is selectable. In modern vehicles there is a deep one for aerodynamic reasons sloping bonnet desired. That requires a certain required Cooling surface a very wide and low cooler package.
  • the cooler package projects beyond the projection of the circular area of the fan on at least one Side (with asymmetrical arrangement), but mostly on both sides and the circular area in turn overhangs the upper edge of the cooler package. Has this unfavorable flow offset to overcome the fan frame, which is hardly possible due to the small axial distance is. Areas of the cooler package and not sufficiently flowed through or not formed insufficiently inflated sectors on the cooling fan. These areas and sectors are can be seen in DE-OS 24 39 033.
  • this is achieved in that the fan frame in which the projection of the cooling fan laterally projecting part with a vertical flow channel in the vertical flow direction increasing cross section and in which the projection of the Radiator package protruding part forms a collecting space, the vertical flow channel merges into the collecting room and the collecting room to which the projection part of the cooling fan projecting from the cooler package is open.
  • the collecting space can the cooler package in the overlap the direction of the radiator fan (claim 2) and can the vertical Flow channel surround the fan ring on the outside (claim 3).
  • This will Large cross sections of the vertical flow channel without increasing the installation dimensions and the collecting space and the fan frame can be a manufacturing technology special get practical shape.
  • the bonnet can then be guided particularly flat.
  • a vertical flow channel is arranged on both sides of the fan frame (claim 4).
  • the flow cross section of the vertical Flow channel chosen so that it increases in the amount of the coated cooler surface. As a result, the flow velocities in the channel remain approximately the same, so that Minimum flow loss occurs.
  • the load-bearing structure of the vehicle is symbolized by a side member 1.
  • a cooler package 2 in a known manner via vibration damping Items stored.
  • An engine compartment panel 3 connects to the radiator package 2 at the top and may form a bulkhead. It is also part of the vehicle structure and serves as Threshold for a bonnet 4, which is connected to the engine compartment panel 3 by means of a lock 5 can be locked.
  • a grille 6 and a bumper 7 are only hinted at.
  • a fan frame 8 extends from a fan ring 9 to to the rectangular cooler package 2.
  • the fan ring 9 surrounds a cooling fan with some play 10, as is customary an axial fan, either on the not shown Motor attached and driven by it, or by its own drive motor (not shown) is driven and is attached to the fan frame 8.
  • a fan frame designed according to the invention is collectively designated 18. It can be made of sheet metal or a single plastic part. It ranges from the circular fan frame 9 up to the cooler package 2. There it forms a lower connection edge 19, a side connecting edge 20 and an upper connecting edge 21. Die Fan frame 18 forms a vertical flow channel behind parts 12 of cooler package 2 23, the cross section of which is determined by its width and depth. The depth is given by a cover surface 24.
  • the modified form according to FIGS. 6, 7, 8 differs from the previous one in that that the fan frame 28 forms a collecting space 32 which has an additional space 35 is enlarged. This arises from the fact that the vertical flow channels 33 the fan ring 9 completely.
  • the flow channels 33 can be deeper, the location the top surface 34 is indicated in FIG. 6, for example.
  • the fan frames designed according to the invention can be used without increasing the distance the entire area of the cooler pack 2 between the cooler pack 2 and the fan 10 are effectively flowed through, regardless of the position of the axis of the cooling fan 10 and the position of the cooler package 2.
  • the cross-sectional profiles are vertical flow channels within the framework of the rules known from fan construction adaptable to aerodynamic requirements.
