The disclosure provides cooling systems for cooling electric machines within electrified vehicles. This disclosure details cooling systems for cooling electric components, such as electric machines, within electrified vehicles. Exemplary cooling systems may include a spray bar positioned relative to a rear face of a stator of the electric machine. In some embodiments, the spray bar may be positioned axially between the rear face of the stator and a torque converter housing. One or more nozzles of the spray bar are configured to direct a coolant between adjacent back irons of the stator, onto end windings of the stator, or both. Actively cooling the stator allows the electric machine to operate at higher torques and speeds, thereby increasing performance.
本公开提供了“用于冷却电动化车辆内的电机的冷却系统”。本公开详细说明了用于冷却电动化车辆内的诸如电机等电气部件的冷却系统。示例性冷却系统可包括相对于所述电机的定子的后面定位的喷杆。在一些实施例中,所述喷杆可轴向地定位在所述定子的所述后面与变矩器壳体之间。所述喷杆的一个或多个喷嘴被配置成将冷却剂引导到所述定子的相邻背铁之间,引导到所述定子的端部绕组上,或这两者。积极地冷却所述定子允许所述电机以更高的扭矩和速度运行,从而提高性能。
