Research Progress of Cooling System for Modern Vehicle Engine

The development status, influencing factors and existing problems of cooling system were briefly analyzed, and the front design concept and research method like the intelligent electronic-controlled cooling, precise cooling, spilt cooling, air-side flow and vehicle thermal management for engine cooling system were also introduced. The high efficiency and low consumption realized with modern engine cooling system were discussed, it was pointed out that the integration of precise cooling and split cooling with electronic-controlled elements was the feasible method, and the vehicle thermal management would be the main method to improve the cooling performance entirely.
