Cooling device for vehicle components
Methods and systems are provided for a cooling device connected to components of a motor vehicle. The cooling device influencing a fluid flow moving past the vehicle components. In one example, a system may include a cooling device positioned below an oil sump. The cooling device may feature an apparatus such that a fluid flows between the apparatus and oil sump. The cooling device may also be positioned below a transmission housing.
1. A drive unit for a motor vehicle having:
a motor with a motor oil sump;
a transmission with a transmission housing; and
a cooling device including a flow-guiding apparatus and a fastening apparatus, wherein the cooling device extends from a first end of the motor oil sump and to a second of the transmission housing opposite the first end of the motor oil sump, and the cooling device is fastened by the fastening apparatus;
the flow-guiding apparatus is arranged spaced apart from the motor oil sump and the transmission housing such that a cooling fluid may flow between the flow-guiding apparatus and the motor oil sump in a first section and the flow-guiding apparatus and the transmission housing in a second section, and a gap in the flow-guiding apparatus allows air flow to enter the flow-guiding apparatus between the first section and the second section.
2. The drive unit of claim 1 , wherein the flow-guiding apparatus has a planar shape and the planar shape bends at least once to vary a distance between the planar shape and the motor oil sump or the transmission housing.
3. The drive unit of claim 1 , wherein the flow-guiding apparatus is composed of metal.
4. The drive unit of claim 3 , wherein a distance between the first section of the flow-guiding apparatus and the motor oil sump varies, a distance between the second section and the transmission housing varies, and the variations in distance change with bends in a planar shape.
5. The drive unit of claim 4 , wherein the planar shape transitions at a bend from an orientation parallel with the motor oil sump or transmission housing to an orientation where a distance between the flow-guiding apparatus and the motor oil sump or the transmission housing decreases as the planar shape extends in a direction of the cooling fluid flow.
6. The drive unit of claim 4 , wherein a bend in the planar shape forms a spoiler edge which increases the distance between the planar shape and the motor oil sump or the transmission housing.
7. The drive unit of claim 6 , wherein the spoiler edge creates vacuum pressure.
8. The drive unit of claim 1 , wherein the motor oil sump and the transmission housing have ribs which fit within grooves of the flow-guiding apparatus.
9. A cooling device for a motor vehicle:
the cooling device positioned below a motor oil sump, and the cooling device including a flow-guiding apparatus and a fastening apparatus;
the flow-guiding apparatus extending along and arranged spaced apart from the motor oil sump, the flow-guiding apparatus formed as a plate comprising one or more bends and each bend changing the orientation of the plate relative to the motor oil sump;
a first portion of the plate arranged parallel to or extending toward the motor oil sump, and a second portion of the plate extending further toward the motor oil sump relative to the first portion;
the fastening apparatus connecting the cooling device and the motor oil sump such that a cooling fluid may flow between the flow-guiding apparatus the motor oil sump; and
ribs extending downward from the motor oil sump and the ribs fit within grooves within the flow-guiding apparatus.
10. The cooling device of claim 9 , wherein the flow-guiding apparatus includes two sections, a first section below the motor oil sump, and a second section below a transmission housing, and a gap between the first section and the second section allows cooling fluid to enter between the sections.
11. The cooling device of claim 10 , wherein the flow-guiding apparatus is a metal sheet, and
in a third portion, the plate is oriented such that a distance between the flow-guiding apparatus and the motor oil sump or transmission housing increases as the plate extends in a direction opposite the cooling fluid flow.
12. The cooling device of claim 11 , wherein in a fourth portion, a distance between the flow-guiding apparatus and the transmission housing increases as the plate extends in a direction of the cooling fluid flow.
13. The cooling device of claim 9 , wherein the one or more bends in the plate are formed to reduce downforce.
14. The cooling device of claim 9 , wherein each side of the groove and each side of the rib form face sharing contact.
15. A cooling device for a motor vehicle:
the cooling device connected to a transmission housing;
the cooling device including a flow-guiding apparatus and a fastening apparatus;
the flow-guiding apparatus formed as a plate extending along the transmission housing such that a cooling fluid may flow between the flow-guiding apparatus the transmission housing, and the plate comprising two or more bends which change an orientation of the plate relative to the transmission housing;
grooves within the plate of the flow-guiding apparatus which receive ribs of the transmission housing; and
the fastening apparatus connecting the cooling device and to planar shaped ribs extending from the transmission housing.
16. The cooling device of claim 15 , wherein a second section of the flow-guiding apparatus is further connected to a motor oil sump, and
the flow-guiding apparatus includes cooling fluid inlets positioned between the second section of the flow-guiding apparatus and a first section of the flow-guiding apparatus connected to the transmission housing.
17. The cooling device of claim 16 , wherein the flow-guiding apparatus is composed of plastic and includes rounded contours.
18. The cooling device of claim 15 , wherein the flow-guiding apparatus extends from a front of an engine to a rear of the transmission housing.
19. The cooling device of claim 18 , wherein the flow-guiding apparatus is a single component.
