Definitions
- the invention relates to a cooling device for the internal combustion engine of a motor vehicle, consisting of a cooling fan, a cooler package and a fan frame, which extends from a fan ring surrounding the cooling fan to the cooler package, the cooler package projecting the cooling fan laterally and projecting of the cooling fan projects above and / or below the cooler package.
- Such a cooling device is described for example in DE-OS 24 39 033.
- the fan is driven by a V-belt, as is common in vehicles with a longitudinal engine. It covers a circular area, the height of which is mostly unfavorable due to the drive and can only be selected within narrow limits. In modern vehicles, a deeply sloping bonnet is desirable for aerodynamic reasons. With a certain required cooling surface, this requires a very wide and low cooler package.
- the cooler package projects beyond the projection of the circular area of the fan at least on one side (in the case of an asymmetrical arrangement), but usually on both sides, and the circular area in turn projects beyond the upper edge of the cooler package.
- the fan frame has to overcome this unfavorable flow offset, which is hardly possible due to the small axial distance. Areas of the cooler package with insufficient or no flow and sectors with insufficient flow occur on the cooling fan. These areas and sectors can be seen in DE-OS 24 39 033.
- cooling system fails in certain critical situations (stationary operation in countries with a hot climate, possibly still with the air conditioning switched on, driving uphill under full load, etc.) or through complex and costly additional measures (oversized parts, additional electrical fan, temperature-controlled shutdown of additional heat sources, etc.) ) must be secured.
- the fan frame forms a vertical flow channel in the part projecting laterally from the projection of the cooling fan and a part in the part projecting over the cooler package, which is flow-connected to the vertical flow channel and open to the cooling fan.
- the areas of the cooler package which are not flowed through according to the prior art are connected via the vertical flow channel and the collecting space to the insufficiently flowed sector of the cooling fan. Both areas are used.
- the cooling capacity increased by 8% during simulated mountain travel with a maximum train weight and even by 25% when the stand was idling.
- a vertical flow channel is provided on both sides or only on one side of the fan ring.
- the collecting space is generally formed above the cooler package, but depending on the assignment, it could also be formed below the cooler package or above and below.
- the collecting space can overlap the cooler package in the longitudinal direction of the vehicle (claim 2) and the vertical flow channel can encompass the outside of the fan ring (claim 3).
- the fan frame can be given a particularly practical shape in terms of production technology.
- 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 is selected 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 a minimum of flow losses occurs.
- Fig.l cooling device according to the prior art, schematically in longitudinal section;
- Fig.2 View according to II in Fig.l;
- Fig.4 View in the direction of travel to Fig.3;
- Fig.5 Horizontal section according to VV in Fig.3; 6: longitudinal section through a second embodiment of the cooling device according to the invention; Fig.7: View in the direction of travel to Fig.6; Fig. 8: Horizontal section according to VIII-VIII in Fig. 6.
- FIG.l and 2 the load-bearing structure of the vehicle is symbolized by a side member 1.
- a cooler pack 2 is mounted on this in a known manner via vibration-damping elements.
- 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 a threshold for an engine hood 4, which can be locked to the engine compartment panel 3 by means of a lock 5.
- a grille 6 and a bumper 7 are only hinted at.
- a fan frame 8 extends from a fan ring 9 to the rectangular cooler package 2.
- the fan ring 9 surrounds, with some play, a cooling fan 10, as is customary an axial fan, which is either attached to the motor (not shown) and driven by it, or is driven by its own drive motor (not shown) and is attached to the fan frame 8.
- FIG. 2 it can be seen that the part 11 of the surface covered by the fan 10 projects beyond the cooler pack 2 and that a part 12 of the surface of the cooler pack is not covered by the projection of the cooling fan 10.
- the fan frame 8 therefore runs laterally to the cooling fan 10 practically transverse to the direction of travel, so that the part 12 of the cooler package 2 is practically not flowed through.
- 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 extends from the circular fan frame 9 to the cooler package 2. There it forms a lower connecting edge 19, a lateral one Connection edge 20 and an upper connection edge 21.
- the fan frame 18 forms behind the parts 12 of the cooler package 2 a vertical flow channel 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 FIG. 6, 7, 8 differs from the previous one in that the fan frame 28 forms a collecting space 32, which is enlarged by an additional space 35. This arises from the fact that the vertical flow channels 33 completely surround the fan ring 9. The flow channels 33 can be formed deeper, the position of the top surface 34 is indicated in FIG. 6, for example.
- the fan frames designed according to the invention allow the entire surface of the cooler pack 2 to be effectively flowed through without increasing the distance between the cooler pack 2 and the fan 10, irrespective of the position of the axis of the coolant fan 10 and the position of the cooler pack 2.
- the cross-sectional profiles are vertical Flow channels can be adapted to the aerodynamic requirements within the framework of the rules known from fan construction.
