“…Many industrial applications use impinging liquid jet to provide an effective mode of heat transfer, such as electrical motor [1], gearbox [2] and steel rolling [3]. For high-speed transmission systems, such as aircraft engines, turbomachinery, and drive trains, oil-jet is applied to the ball bearing cooling [4].…”

“…It enhanced the thermal performance dramatically. Davin et al [13] and Lim and Kim [14] investigated the influences of the oil flow rate, rotation speed oil inlet temperature and geometric variables on the cooling efficiency of the oil spray cooling system for electric motors. Although a great heat transfer augmentation was always observed in the liquid cooling scheme, an inherent disadvantage is spotted as well: the persistent and stable operation of the cooling system depends on an external fluid circle constitution such as pump package, reservoir, and heat rejection component, which will definitely increase complexity and decrease economy.…”

“…Another important figure that is seldom referenced is the drive system weight, respective of the weight of the electrical machine, inverter, and cooling system. All three components compose the drive system for a fan or propeller drive [2]. The conventional cooling system for electrical machines installed in aircraft, e.g., generators, is oil spray cooling using the oil from the turbine gear.…”
