Shanghai Automotive Wind Tunnel Center research on integrated optimization of thermal management systems based on aerodynamics and thermodynamics, with automobiles and rail transit vehicles as research objects. From the perspectives of aerodynamics and thermodynamics, we study the optimal arrangement and combination of various equipment in the thermal management system, as well as the reasonable distribution of internal flow fields and their impact on heat transfer; We research on comprehensive utilization of thermal energy. Taking automobiles and rail transit vehicles as research objects, we carry out research on air emissions and recovery, and the reuse of thermal energy in power systems, forming key technologies for the comprehensive utilization of thermal energy in ground transportation vehicles and the reduction of exhaust emissions.
