Design of the Parallel Waterway Cooling Structure for Passenger Car Motors and Its Simulation Optimization
Safe and reliable operation of the motor is the guarantee for the stable operation of new energy ve-hicles.The heat generated when the motor is running,is generally taken away by the water circuit set in the casing to realize the motor cooling.The traditional series-con-nected water circuit has a large radial size and weak heat transfer capacity,which does not meet the requirements of miniaturization and high power of the passenger car motors.The parallel water circuit has obvious advantages in weight reduction,better machining and heat transfer performance,but its preliminary design is more complicated.The article researches on the parallel cooling water circuit,simulates& optimizes the parallel water circuit model and compares it with the series water circuit in terms of flow distribution,heat transfer effect and etc.The results show that the heat transfer capacity of the parallel water circuit is obviously better than that of the series water circuit.
