Simulation analysis of integrated water tank for thermal management system of new energy vehicle
Thermal management system plays an important role in new energy vehicles,and the water tank integrated system in thermal management system is the key to ensure the storage and smooth transportation of coolant.In the thermal management module,three modes of electric drive cooling,battery cooling and battery soaking were selected.The water tank integrated system was modeled and simulated by STAR-CCM+,and the internal flow and pressure loss of the water tank integrated system were obtained.The simulation results showed that when in the electric drive cooling,battery cooling and battery soaking mode,the maximum flow rate appeared at the confluence of the five-way valve V3 and V4,with a size of 3.78 m/s,the maximum local pressure appeared at the V5 turning point of the six-way valve,and the pressure difference between the electric drive and the radiator channel was 10 474 Pa.The maximum temperature in the storage tank was 40℃.
