Research on flow simulation of integrated water tank with different structures in thermal management system
In order to study the flow of coolant inside the water tank of the thermal management system of the new energy power assembly,the electric drive cooling mode of the summer working condition was selected.The simulation analysis of the water tank under different working conditions and structural changes was carried out by STAR-CCM+,and the flow of coolant inside the large and small water tanks was studied.The simulation results showed that the flow in the water tank was not improved by changing the flow rate after adding the deflector in the water tank;when the deflector was changed to U-shaped,the internal disturbance of the large water tank was strengthened,and the eddy current phenomenon was generated.Increasing the length of the U-shaped deflector and the number of connected holes in the large and small water tanks,the internal disturbance of the large water tank was further strengthened,and the connectivity of the large and small water tanks was strengthened.
