Abstract

The present application relates to the technical field of vehicles, in particular to a cooling system, a control method and a vehicle, including: a first cooling branch, a second cooling branch and a supercharging device, the first cooling branch and the second cooling The branches are connected in parallel, the first cooling branch and the second cooling branch are provided with channels for cooling working fluid; the booster is used to adjust the pressure in the first cooling branch; the The first cooling branch circuit includes a first component to be cooled and a regulating valve connected in sequence; the second cooling branch circuit includes a pressure regulating device and a second component to be cooled in sequence. Cool the cylinder head and cylinder block respectively by designing the first cooling branch and the second cooling branch to meet the different heat dissipation requirements of the cylinder block and cylinder head; and adjust the heat dissipation of the cylinder block and cylinder head according to the load state of the engine , to realize the rapid change of the heat transfer and the wall surface temperature of the engine water jacket, and reach the optimum working temperature of the engine.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a cooling system, a control method and a vehicle. Background technique [0002] With further restrictions on vehicle fuel consumption and emissions by governments around the world, especially Europe requires that all passenger vehicles CO2 in 2021 2 Emissions must not exceed 95g / km, while electric vehicles are currently 2 Issues such as emissions, cost, and cruising range cannot yet replace fuel vehicles as the mainstream of the market. Therefore, major OEMs still need to invest a lot of resources to improve engine performance, such as efficiency, maximum power, and pollutant emissions. According to the "Technology Roadmap for Energy Saving and New Energy Vehicles" released by the state in 2016, the average thermal efficiency of new passenger cars will reach 44% in 2025 and 48% in 2030. To achieve this goal, it is necessary to focus on the development of engine therma...
