Abstract

The invention relates to the technical field of vehicles, in particular to a cooling system, a control method and a vehicle. The cooling system comprises a first cooling branch circuit, a second cooling branch circuit and a supercharging device, wherein the first cooling branch circuit and the second cooling branch circuit are connected in parallel, channels for cooling working media to flow are internally arranged in the first cooling branch circuit and the second cooling branch circuit, the supercharging device is used for adjusting the pressure in the first cooling branch circuit, the firstcooling branch circuit comprises a first to-be-cooled part and a regulating valve which are connected in sequence, and the second cooling branch circuit comprises a pressure adjusting device and a second to-be-cooled piece which are connected in sequence. The first cooling branch circuit and the second cooling branch circuit are designed to cool a cylinder cover and a cylinder block correspondingly so as to meet different heat dissipation requirements of the cylinder block and the cylinder cover, and the heat dissipating capacity of the cylinder block and the cylinder cover is adjusted according to the load state of the engine, rapid change of heat exchange capacity and engine water jacket wall surface temperature is achieved, and the optimal working temperature of the engine is achieved.

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...
