摘要：
The parameter changes of the vehicle thermal management system affect its performances, so it is necessary to use new methods to concurrently study multiple performance indicators in different dimensions. In this paper, an 1D/3D strongly coupled model of the vehicle thermal management is constructed by using the AMESim and the STAR-CCM+. This model can study various performances including the 3D and 1D temperature and flow fields under different thermal balance conditions at the same time. The corresponding 1D analysis results show that the heat dissipation capability of the cooling system is the worst under climbing condition, and the refrigeration capacity of the air conditioning system is the worst under idle condition. In order to study the influence of the parameter changes of thermal management system on its performance, the effects of the fan and water pump speeds on the cooling capacity of cooling system under climbing condition, and the influence of the fan and compressor speeds on the refrigeration capacity of air conditioning system under idle condition are analyzed. © 2022, Society of Automotive Engineers of China.
