Vehicle cooling system, control method and vehicle

Abstract

The invention provides a vehicle heat dissipation system, a control method and a vehicle. The vehicle heat dissipation system comprises a radiator, a first switch, a second switch and a controller, wherein the radiator comprises a water inlet, a first water outlet, a second water outlet and a partition plate, the first switch is used for controlling opening or closing of the partition plate; the second switch is provided with a first inlet, a second inlet and an outlet and used for controlling conduction or disconnection of an oil cooler circuit and an engine cooling circuit; and when the water temperature of the engine is greater than a first preset temperature and the oil temperature of a transmission is less than a second preset temperature, the first switch and the second switch are controlled to open the partition plate and make the oil cooler heat dissipation circuit communicate with the engine cooling circuit, so that the radiator cools the engine and the oil cooler together. The vehicle heat dissipation system can cool the engine and the oil cooler together under certain conditions, the unreasonable distribution situation of insufficient heat dissipation capacity of the engine and excess heat dissipation of the oil cooler is avoided, the actual heat dissipation requirements of the vehicle are met better, the use requirements are effectively met, and user experiences areimproved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle cooling system, a control method and the vehicle. Background technique [0002] At present, dual-clutch transmissions are gradually becoming the mainstream, and they are mainly divided into two types: dry type and wet type. However, although the dry dual-clutch transmission has a simple structure and low cost, it does not have a separate oil cooling system, resulting in poor reliability; although the wet dual-clutch transmission has a separate oil cooling system and high reliability, it has a complex structure. high cost. [0003] In related technologies, since the wet dual-clutch transmission requires a water-cooling system to dissipate heat, the radiator is generally divided into two parts, one part dissipates heat for the engine, and the other part dissipates heat for the oil cooler, such as a U-type flow radiator or an I-type flow radiator . [0004] However,...

AI Technical Summary

Problems solved by technology

[0004] However, whether it is a U-type flow radiator or an I-type flow radiator, the heat dissipation of the engine and the heat dissipation of the oil cooler are separated and cannot be dissipated together, resulting in an unreasonable distribution of insufficient heat dissipation capacity of the engine and surplus heat dissipation at the end of the oil cooler. In turn, it is easy to make the whole vehicle unable to meet the actual heat dissipation requirements, and there will be phenomena such as limited torque, which will reduce the user experience and cannot meet the use requirements, and needs to be improved.
