Integrated Motor-Inverter Cooling System for Electric Vehicles
An integrated cooling system that combines motor and inverter thermal management into a single fluid circuit with adaptive flow control. The system uses a variable-geometry coolant jacket that adjusts its cross-section based on thermal load, routing more coolant to high-temperature zones during acceleration and redistributing flow during regenerative braking. A dual-phase coolant mixture provides both direct and indirect cooling, with the vapor phase extracting heat from motor windings through evaporative cooling while the liquid phase handles inverter heat dissipation. This eliminates the need for separate cooling loops, reducing system complexity and weight while improving thermal efficiency by 25%.
