Definitions

  • the invention relates to a vehicle with at least one air inlet opening for admitting ambient air, at least one air outlet opening for exhausting the ambient air and an air-cooled cooling device connected to the air inlet opening and the air outlet opening for cooling one or more vehicle components.
  • the air outlet opening is equipped with at least one guide device, which is adjustable and is driven automatically or by an adjustment device on the air outlet side.
  • Such a vehicle is, for example, from the German published patent application DE 10 2013 217 628 A1 known.
  • DE 10 2013 217 628 A1 German published patent application DE 10 2013 217 628 A1 known.
  • deflection grilles rigidly attached deflection grilles in the area of the air outlet opening.
  • a generic rail vehicle is also from the international patent application WO 2019/170602 A1 known, wherein an underfloor equipment carrier for a rail vehicle comprises forced ventilation with at least one supply air intake point and at least one exhaust air outlet opening, an air guiding device being provided which can be switched between at least two positions and wherein in a first position of the air guiding device the exhaust air is in a first outflow direction and in a second position flows out in a second outflow direction.
  • the invention is based on the object of specifying a vehicle with an air outlet opening in which the blowing out of ambient air is optimized.
  • the air outlet opening is equipped with at least one guide device, which is adjustable and is pivoted automatically or driven by an adjustment device on the air outlet side into a forward travel position when driving in the forward direction of travel of the vehicle and into a reverse travel position when driving in the reverse direction of travel of the vehicle different from the forward driving position.
  • a significant advantage of the vehicle according to the invention is that guidance devices in the area of the air outlet opening are adjustable and can therefore be adjusted depending on the direction of travel so that they can achieve a guidance effect adapted to the respective direction of travel.
  • the guide device or at least one of the guide devices is aligned in such a way that when the vehicle is driving, the ambient air blown out through the air outlet opening is blown out in the opposite direction or at least predominantly in the opposite direction to the respective direction of travel, depending on the direction of travel.
  • a thrust force in the direction of travel and thus a reduction in the energy consumption of the vehicle drive can advantageously be achieved.
  • the cooling device is equipped with a fan for sucking in and blowing out ambient air, blowing out in the opposite direction to the direction of travel reduces the necessary fan power because the blown out air is carried away by the wind; Less powerful fans can therefore advantageously be used than with a different blow-out direction.
  • the guide device or at least one of the guide devices has two surfaces, one of which is the windward surface facing the wind both when driving forwards and backwards and the other when driving forwards as well as reverse travel is the leeward surface facing away from the wind.
  • the cooling device comprises a fan which sucks in the ambient air from the air inlet opening and blows it out at the air outlet opening, in each case at a higher flow speed than the driving speed of the vehicle, generating a thrust force that drives the vehicle.
  • the cooling device preferably comprises a heat exchanger which cools a coolant present for cooling vehicle-side operating components with the air flowing over the air inlet opening.
  • the air outlet opening is preferably arranged on the vehicle floor.
  • the ambient air blown out through the air outlet opening when the vehicle is driving is preferably directed against the respective direction of travel or at least predominantly against the respective direction of travel - i.e. preferably parallel to the vehicle floor or essentially parallel to it (preferably with a deviation angle of a maximum of ⁇ 10 ° relative to the horizontal or to the vehicle floor or to the busy one track) - blown out into the gap between the track-side floor and the vehicle floor.
  • the air outlet opening can be arranged in the roof area.
  • the air inlet opening is preferably equipped with one or more guide devices which are adjustable depending on the direction of travel and are aligned automatically or driven by an adjustment device on the air inlet side depending on the direction of travel.
  • the vehicle is preferably a rail vehicle.
  • the air outlet opening is preferably arranged on the rail vehicle floor.
  • the ambient air blown out through the air outlet opening when the vehicle is traveling is preferably blown out into the gap between the track bed and the vehicle floor in the opposite direction to the respective direction of travel.
  • the Figure 1 shows a schematic side view of an exemplary embodiment of a vehicle 10 according to the invention when traveling in the forward direction of travel, which is shown in Figure 1 is marked with an arrow and the reference symbol VFR.
  • the vehicle 10 is preferably a rail vehicle.
  • the vehicle 10 has an air inlet opening 20 in the area of a side wall 11, which is connected to a cooling device 30.
  • the air inlet opening 20 is equipped with air inlet-side guide devices 21, which operate automatically or by means of one in the Figure 1 For reasons of clarity, the air inlet adjustment device is not shown can be adjusted depending on the direction of travel.
  • the guide devices 21 are preferably guide plates.
  • the cooling device 30 is equipped with a fan 31, which sucks in ambient air U through the air inlet opening 20 during operation.
  • the cooling device 30 is used to cool one or more vehicle components, for example in the Figure 1 one is shown and marked with the reference numeral 40.
  • the cooling device 30 is connected to an air outlet opening 50, which releases the ambient air U sucked in by the fan 31 via the air inlet opening 20 back into the vehicle environment.
  • the air outlet opening 50 is equipped with air outlet-side guide devices 51, which operate automatically or by means of one in the Figure 1 For reasons of clarity, the air outlet side adjustment device, which is not shown, can be adjusted depending on the direction of travel.
  • the guide devices 51 are preferably guide plates.
  • the Figure 1 shows the position of the guide devices 51 when driving forward. It can be seen that the guide devices 51 direct the ambient air U blown out by the fan 31 against the respective direction of travel, in Figure 1 i.e. blow out against the forward direction of travel VFR, so that the blown out ambient air U generates an impulse or a thrust force FS, which drives the vehicle 10.
  • the position of the guide devices 51 shown is not only advantageous with regard to a driving thrust force FS, but it also prevents the blown-out ambient air U from hitting the ground on the track side, which is driven on by the vehicle 10, vertically or at least head-on. If the vehicle 10 is, for example, a rail vehicle and the trackside floor is a track bed 60, then air can be blown out by the fan 31 Air can lead to turbulence and gravel flying in the track bed 60 if the air hits the track bed 60 head-on or too head-on; this is advantageously avoided by the deflection or the guide devices 51.
  • the Figure 2 shows the vehicle 10 according to Figure 1 when reversing, i.e. along the reverse direction marked with the arrow and the reference symbol RFR. It can be seen that when reversing, the guide devices 51 in the area of the air outlet opening 50 have been changed, for example pivoted, automatically or by an adjusting device not shown, and now the ambient air blown out by the fan 31 is directed counter to the reverse direction RFR or along the forward direction VFR blow out, which means - analogous to the forward direction of travel VFR Figure 1 - a thrust force FS is generated in the respective direction of travel.
  • the Figure 3 shows in more detail an exemplary embodiment of an advantageous embodiment of the guide devices 51, which are in the area of the air outlet opening 50 in the vehicle 10 according to Figures 1 and 2 can be used. It can be seen that the guide devices 51 are each arcuate and have an outer or convex surface and an inner or concave surface.
  • the guide devices 50 can each be pivoted about a pivot axis S, be it automatically or by an indicated adjustment device 70.
  • the adjustment device 70 is preferably adjusted by a direction of travel signal SF, which indicates the respective direction of travel and, for example, from a direction sensor or a vehicle control device can be provided.
  • the Figure 4 shows again in another representation the guidance devices 51 when traveling along the forward direction of travel VFR. It can be seen that the guide devices 51 are aligned in such a way that the convex surfaces 51a of the guide devices 51 face the wind W and the concave surfaces 51b of the guide devices 51 face away from the wind W. The convex surfaces 51a thus form the windward surfaces and the concave surfaces 51b form the leeward surfaces.
  • the shows Figure 4 the redirection of the ambient air U ejected by the cooling device 30 by means of the concave, leeward surface 51b of the guide devices 51 in such a way that the ambient air U is directed in the direction or along the direction of the airstream W and parallel to the vehicle floor 12.
  • the Figure 5 shows the orientation of the guide devices 51 when reversing along the reverse direction RFR according to Figure 2 . It can be seen that the guide devices 51 have now been pivoted about the pivot axis S and therefore the convex surfaces 51a of the guide devices continue to face the wind W. The concave surfaces 51b of the guide devices 51 are again on the leeward side.
  • Figure 5 detect the redirection of the ambient air expelled by the cooling device 30 along the direction of the wind and parallel to the vehicle floor 12.
  • the Figure 6 shows the vehicle 10 according to Figure 1 when driving forward along the forward direction VFR in a top view. It can be seen that the air inlet opening 20 is arranged in the area of the side wall 11 and has air inlet-side guide devices 21, which can be adjusted depending on the direction of travel.
  • the air inlet side guide devices 21 are aligned such that airflow W is introduced into the air inlet opening 20.
  • FIG 7 shows - also in a top view - the vehicle 10 according to Figures 1 and 2 when reversing along the reverse direction RFR. It can be seen that the air inlet-side guide devices 21 have now been adjusted or pivoted and are again aligned in the direction of the wind W, so that the wind W is introduced into the air inlet opening 20.
  • the adjustment also ensures that one surface of the guide devices is always the windward surface (based on the airstream W) and the other surface is always the leeward surface.
  • the air inlet-side guide devices 21 are each curved and each have concave windward-side surfaces and convex leeward-side surfaces, analogous to the air outlet-side guide devices 51, as exemplified in connection with Figures 3 , 4 and 5 have been explained.
