[0070] Since the power assembly 100 comprises the integrated oil sump assembly 100, the oil pump 20, the immersion oil cooler 40 and the oil filter system 30 in the integrated oil sump assembly 100 are integrated in the oil storage shell 10, the oil pump 20, the immersion oil cooler 40 and the oil filter system 30 do not separately occupy space inside the power assembly shell, and long pipelines are not needed to connect the oil pump 20, the immersion oil cooler 40 and the oil filter system 30, thereby reducing the space occupied by the long pipelines inside the power assembly shell, effectively saving the space inside the power assembly shell, and thereby the volume of the power assembly shell can be reduced to reduce the space occupied by the power assembly shell in the vehicle.

[0071] The above merely illustrates the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the technical concept of the present application and by using the content of the present application specification and drawings are included in the patent protection scope of the present application.

Claims

1. An integrated oil pan assembly, characterized in that, include: An oil storage tank having an inner cavity, and a first oil inlet, a first oil outlet, a first water inlet, and a first water outlet communicating with the inner cavity; The inner cavity is equipped with an oil filtration system and an immersion oil cooler. The immersion oil cooler includes a second water inlet and a second water outlet. The second water inlet is sealed to the first water inlet, and the second water outlet is sealed to the first water outlet. The integrated oil pan also includes an oil pump, which is disposed adjacent to the oil storage tank, or the oil pump is disposed inside the inner cavity; when the oil pump is working, the oil flowing in through the first oil inlet is filtered by the oil filter system and then transmitted to the submersible oil cooler, so that the oil is fully in contact with the submersible oil cooler and cooled before flowing out through the first oil outlet.

2. The integrated oil pan assembly as described in claim 1, characterized in that, The oil filtration system includes a suction filter that is disposed adjacent to and communicates with the second oil inlet of the oil pump.

3. The integrated oil pan assembly as described in claim 2, characterized in that, An oil passage is formed on the inner surface of the inner cavity. The oil passage is located between the first oil inlet and the suction filter, and is used to transfer the oil flowing in from the first oil inlet to the suction filter.

4. The integrated oil pan assembly as described in any one of claims 1 to 3, characterized in that, The oil filtration system includes a filter press that is disposed adjacent to and communicates with the second oil outlet of the oil pump.

5. The integrated oil pan assembly as described in claim 4, characterized in that, The submersible oil cooler is located below the filter press.

6. The integrated oil pan assembly as described in claim 1, characterized in that, The immersion oil cooler includes multiple stacked liquid cooling plates with gaps between adjacent liquid cooling plates. The second water inlets of the multiple liquid cooling plates are interconnected to form the second water inlet of the immersion oil cooler, and the second water outlets of the multiple liquid cooling plates are interconnected to form the second water outlet of the immersion oil cooler.

7. The integrated oil pan assembly as described in claim 6, characterized in that, The liquid cooling plate is a harmonica tube type liquid cooling plate.

8. The integrated oil pan assembly as described in claim 6, characterized in that, The surface of the liquid cooling plate is provided with heat dissipation protrusions.

9. A powertrain, characterized in that, Includes the integrated oil pan assembly as described in any one of claims 1 to 8.

10. A car, characterized in that, Including the powertrain as described in claim 9.
