Problems solved by technology
In related technologies, the transmission cooling system is not directly coupled to the engine cooling system, and the coolant used for the transmission oil cooler comes from the outlet or inlet of the engine. Since the temperature of the coolant at the engine outlet is between 110°C and 120°C During the period, the cooling capacity of the gearbox oil cooler is limited, which cannot meet the actual needs. The temperature of the coolant at the inlet is lower than that at the outlet, which can meet the gearbox with an oil temperature limit of 130°C, but cannot meet the oil temperature limit of 130°C. The cooling requirements of the gearbox at 90°C, that is, the difference between the temperature of the coolant used in the gearbox and the temperature of the lubricating oil is small, and the cooling capacity is poor, which cannot meet the heat dissipation requirements of the engine and gearbox

Embodiment Construction
[0037] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0038] In this disclosure, unless stated to the contrary, the use of orientation words such as "inside and outside" generally refers to the inside and outside of the corresponding component contour, and "upstream" and "downstream" refer to the inner cooling relative to the pipeline. In terms of the flow direction of the liquid, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequence or importance. In addition, when the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwis...

The present disclosure relates to a powertrain cooling system and a vehicle, the powertrain cooling system includes an oil cooler of a gearbox and a radiator connected to an engine coolant circulation, and the radiator includes a separated first heat dissipation portion and the second cooling part, the first cooling part and the coolant flowing out of the oil cooler are mixed, and part of the mixed cooling liquid flows through the second cooling part, the oil cooler and returns to the engine through the water pipe in sequence . In this way, the part of the coolant flowing out of the first heat dissipation part and the oil cooler can enter the second heat dissipation part for secondary cooling, further reducing the temperature of the coolant, which can meet the heat dissipation requirements of the gearbox. The powertrain cooling provided by the present disclosure The system can meet the heat dissipation requirements of the engine and gearbox at the same time, and further improves the heat dissipation effect of the lubricating oil in the oil cooler. The overall structure is compact and occupies a small space.
Description
technical field [0001] The present disclosure relates to the field of powertrain cooling, in particular, to a powertrain cooling system and a vehicle. Background technique [0002] With the development of powertrain high-temperature cooling technology and the deepening of research, at present, when the engine is working normally, the temperature of the coolant at the outlet can reach 110°C-120°C. At the same time, according to the requirements of environmental protection and energy consumption regulations, powertrain It needs to be matched with a gearbox with multiple gears and wide speed ratios. The temperature of the lubricating oil in this gearbox needs to be controlled within 130°C, and even higher requirements need to be controlled within 90°C to ensure the lubrication effect and reduce frictional resistance. . In related technologies, the transmission cooling system is not directly coupled to the engine cooling system, and the coolant used for the transmission oil coo...
