Definitions

  • the invention relates to a cooling system for motor vehicles with the features of Preamble in claim 1.
  • the cooling system is in the as yet unpublished German application DE 199 50 755.4, but also in a number of other publications (EP 1 045 217 A1) have been described. In the unpublished application, the same Applicant heard, it is about increasing the efficiency of the cooling system improve what is there by an optimized position of the radial impeller inside the cooling system is reached.
  • the cooling systems of the type described in the preamble are fundamentally more efficient than conventional cooling systems with one behind the other in the direction of cooling air flow arranged individual coolers, because in the cooling systems of the type described Centrifugal fans can be used.
  • the cooling system for motor vehicles the question of efficiency from the point of view of the overall energy balance of the vehicle.
  • the mostly electric or fan driven directly by the motor that blocks the flow of cooling air through the cooling network the cooler sucks through, is only put into operation when necessary.
  • the dynamic pressure is sufficient to provide sufficient cooling capacity to make available because of the larger in conventional cooling systems
  • Cross section allows a relatively high volume flow of cooling air.
  • a box-shaped cooling system in which the Cooling network surface of one of the coolers arranged on the outside of the cooler Sliding blind can be covered or opened to increase the volume flow to be able to vary the cooling network area of the other coolers as required.
  • the object of the present invention is to determine the volume flow Increase cooling air in dynamic pressure operation of the cooling system without the effectiveness of Radial fan significantly impair during its operating phases.
  • the cooling system of the motor vehicle can thus work in a back pressure operation over a larger operating range, d. H. without that Radial fan to start up, which means less energy is required.
  • the start-up frequency and the on-time of the radial fan were determined by the Invention reduces, which also leads to reduced fuel consumption.
  • the openings have covers (closure elements) that how check valves work. This effect can easily be achieved through the Arrangement of rubber tabs on the inside of the front wall can be achieved which are opened by the dynamic pressure when the centrifugal fan is not in operation is. If the radial fan is in operation, it ensures that it is inside the cooling system there is pressure to keep the covers closed.
  • the covers are above or to the side of the openings and preferably on the inside attached to the front wall.
  • closure elements and mechanisms are the subject of claims 5 to 9. These are around flexible or rigid closure elements which can be moved by means of suitable mechanisms, via signals - for example together with the commissioning or Switching off the radial fan - can be controlled or moved.
  • Such locking mechanisms are generally somewhat more complex. However, they can be functional Have advantages that consist, for example, in low noise or in that the openings are more closable, so that the escape of unused cooling air in the operational phases of the radial fan is as complete as possible is prevented.
  • Movable via driven rollers Covers or the like go for example from DE-OS 25 01 013 out.
  • DE-OS a roller belt filter is used by means of the roller drive there moved, but the roller drive shown there itself is also present Context suitable.
  • the reference to these documents is intended to be a more detailed one Replace representation.
  • the cover can be made entirely of flexible material exist or only be flexible in the area that can be wound up or unwound, whereby the cover itself can be a rigid plate, which in by means of the roller drive upper and lower guides, which are arranged on the front panel, movable which opens or closes the openings.
  • the shape, number and arrangement of the openings in the front wall can be any and depends on how large the additional volume flow should be, how it should distribute which locking elements and locking mechanisms selected are, of course, also in terms of strength and stability, if the front wall serves as a load-bearing element of the cooling system and after other structural or functional restrictions.
  • Fig. 1 perspective view of the front wall of the cooling system
  • Fig. 2 vertical section along the line II - II in Fig. 1;
  • Fig. 3 vertical section along the line III - III in Fig. 1;
  • the cooling system consists of water coolers 1 arranged on the right and left ; 2 and an intercooler 3 arranged at the top and is intended for heavy motor vehicles.
  • the cooling network 20 of the charge air cooler 3 is significantly greater in its block depth 30 than the block depth 30 of the water cooler 1; 2.
  • the block width has the reference number 31 and is also larger in the charge air cooler 3 than in the water coolers 1; 2. In this embodiment there is no cooler at the bottom.
  • the underside is therefore closed by the wall 26 (Fig. 3).
  • the rear of the cooling system which is not clearly shown, is closed by a wall.
  • the front wall 12 there is an intake opening 11 with a nozzle 10, which in this exemplary embodiment was not arranged centrally in the front wall 12, but was shifted slightly to the upper area.
  • the exhaust blades 7 and the rear wall 9 of the impeller of the radial fan 6 can be seen in the suction opening 11 .
  • the axis 5 of the radial fan 6 has been identified by a dashed line. In the direction of this axis 5 , the cooling air is sucked in, deflected radially and in the direction of the cooler 1; 2; 3 blown.
  • the cooler 1; 2; 3 have a known cooling network 20, consisting of flat tubes 22 with corrugated fins 23 arranged between them , the cooling network 20 being shown in more detail in FIG. 2.
  • the flat tubes 22 each extend between the two header boxes 21 of the individual coolers 1; 2; 3, so that they run transversely to the fan axis 5 .
  • a total of nine openings 13 are present in the front wall 12 , two openings 13 at the top, one on each side, and the remaining seven openings 13 below the suction opening 11 .
  • the front wall 12 is exposed to the wind when the motor vehicle is in motion.
  • the openings 13 are essentially rectangular openings, the shape, number and arrangement of the openings 13 not being particularly important.
  • the coverable openings 13 or essential parts of the front wall 12 are designed like a grill, that is to say, for example, in the manner of a radiator grill.
  • the upper two openings 13 have been drawn in the open state, ie the cover 15 protrudes on one side inwards, so that cooling air flowing in from outside can penetrate through the openings 13 into the interior of the cooling system when the motor vehicle is in motion.
  • the lower openings 13 were drawn closed, it being understood that this was drawn for the sake of clarity only.
  • all openings 13 are open, and in operation of the radial fan 6 , however, all openings 13 are closed by means of the covers 14 .
  • the covers 14 are made of a suitable rubber. They are attached to the inside of the front wall 12 above the openings 13 . The attachment is of course also possible on the outside of the front wall 12 .
  • the cover 14 itself must be arranged on the inside of the front wall 12 in this exemplary embodiment.
  • the attachment is stable, so that the permanent function of the covers 14 is ensured over the entire period of use of the cooling system.
  • a cover 14 can be seen in FIG. 2. 2 shows the cover 14 in a position as it is present in the back pressure operation of the cooling system, but at all openings 13 .
  • the covers 14 can also be constructed differently.
  • a single cover 14 does not necessarily have to be assigned to each individual opening 13 . Several preferably smaller openings 13 can be closed by means of a single cover 14 .
  • FIG. 2 also shows more clearly than FIG. 1 that the charge air cooler 3 also has a larger block width 31 in addition to the larger block depth 30 , so that there is a clear projection 32 of the charge air cooler 3 to the front over the front wall 12 .
  • Such measures can best meet the cooling requirements for each individual cooler in a specific application.
  • the excess 32 is compensated for by means of a cover plate 25 .
  • each opening 13 has an extra cover 14 , which is advantageous in the selected size of the openings 13 because a better seal is expected when the radial fan 6 is in operation. Furthermore, the size of the covers 14 must of course be selected on the one hand so that they cannot get into the radial impeller or be damaged and on the other hand that they can keep the openings 13 sufficiently tightly closed.
