Abstract
In order to solve the problem that engine coolant outlet temperature of an SUV was too high in low and medium speed climbing and high speed conditions, 1D/3D co-simulation tool were used to establish a simulation model of whole vehicle cooling system. Through test and simulation, different factors that affect cooling system thermal balance performance were analyzed. The research found out that: Independent cooling loop for transmission and engine can significantly reduce engine coolant outlet temperature. Cooling system pipe arrangement has an influence on coolant flow distribution, but has little influence on coolant temperature. By optimizing radiator type and underhood arrangement, underhood flow field characteristics can be improved and inlet air flow rate of cooling system was increased. So the cooling system capacity has been improved.
