Problems solved by technology
The traditional cooling system uses mechanically driven cooling water pumps and cooling fans. The flow rate of the cooling medium depends on the engine speed rather than the actual cooling demand of the engine during actual operation. Obviously, it is impossible to achieve reasonable control of the engine water temperature in full operating conditions.
In addition, these components consume a lot of power. For example, the power consumed by the fan can reach 10% of the total power output of the engine.

Description
technical field [0001] The invention belongs to the technical field of automatic control, and more specifically, belongs to an intelligent cooling system for a vehicle engine. Background technique [0002] With the growth of global car ownership, while cars bring convenience to people, they also bring unprecedented pressure on energy and the environment, and people's demand for use is also increasing day by day. At the same time, as an important subsystem of the vehicle and the engine, the cooling system has also achieved corresponding development in its technical level and plays an increasingly important role. [0003] At present, most engine cooling systems are still traditional passive systems, which can only regulate the heat distribution of the engine and the vehicle to a limited extent. However, with the rapid development of electronic technology and computer technology, the technology of electronic control parts is mature, and the intelligence and automation of cooli...
