Air-guiding device
View Patent ↗A device for cooling a transmission unit having front cooling fins and rear cooling fins includes a front air guiding blade and a rear air guiding blade. The front air guiding blade is configured to guide air from the underbody flow to the front cooling fins. The rear air guiding blade is configured to guide air from the underbody flow to the rear cooling fins.
1. A device for cooling a transmission unit, the transmission unit having front cooling fins and rear cooling fins, the device comprising:
a front air-guiding blade; and
a rear air-guiding blade,
wherein the front air-guiding blade is configured to guide air from an underbody flow to the front cooling fins,
wherein the rear air-guiding blade is configured to guide air from the underbody flow to the rear cooling fins, and
wherein the front air-guiding blade has a convex and a concave region.
2. The device as claimed in claim 1 , wherein the front air-guiding blade is further configured to guide air from the underbody flow to the rear cooling fins.
3. The device as claimed in claim 1 , wherein a lower edge of the rear air-guiding blade is arranged in a vertical direction at a same height as a lower edge of the front air-guiding blade.
4. The device as claimed in claim 1 , wherein the front air-guiding blade and the rear air-guiding blade are formed substantially integrally.
5. The device as claimed in claim 1 , wherein the device has a plurality of fastening points which are configured to be fastenable to the vehicle or transmission unit.
6. The device as claimed in claim 5 , wherein at least one of the plurality of fastening points is configured to be fastenable to a laterally arranged wall of the transmission unit.
7. The device as claimed in claim 5 , wherein at least one of the plurality of fastening points is configured to be fastenable to a lower side of the transmission unit.
8. A device for cooling a transmission unit, the transmission unit having front cooling fins and rear cooling fins, the device comprising:
a front air-guiding blade; and
a rear air-guiding blade,
wherein the front air-guiding blade is configured to guide air from an underbody flow to the front cooling fins,
wherein the rear air-guiding blade is configured to guide air from the underbody flow to the rear cooling fins,
wherein a lower edge of the rear air-guiding blade is arranged in a vertical direction above a lower edge of the front air-guiding blade.
9. A device for providing cooling to a transmission unit of a vehicle, the transmission unit having front cooling fins and rear cooling fins arranged one behind the other with respect to a longitudinal axis of the vehicle oriented by a direction of travel, the device being configured to attach to the transmission unit at an underside of the vehicle, the device comprising:
a front air-guiding blade; and
a rear air-guiding blade arranged behind the front air-guiding blade with respect to the direction of an underbody flow,
wherein the front air-guiding blade is configured to guide air from the underbody flow to the front cooling fins,
wherein the rear air-guiding blade is configured to guide air from the underbody flow to the rear cooling fins,
wherein the front air guiding blade has a profile with a concave region and a convex region, the concave region being located in front of the convex region, the convex region being at a portion of the front air guiding blade configured to be arranged closer to the transmission unit.
