Preliminary test results of reflux-cooled electromechanical actuator

Study of heat pipe in motor cooling: A review

“…Schneider 9 et al, in 1994, proposed a thermal siphon tube cooling device for permanent magnet motors with electric actuators, where gravity heat pipes are arranged along the radial direction in the motor housing to achieve cooling of the motor, ensuring that the motor temperature does not exceed the limit temperature and achieving a motor temperature drop up to 90 K. In 2016, Xiaozhi Qiu 10 et al designed a loop heat pipe cooling system for airborne electromechanical actuators with permanent magnet synchronous motors that can better adapt to the working conditions of the electromechanical actuator with fully enclosed structure and no internal ventilation, and achieves a better cooling effect. The cooling system uses a flat plate evaporator with water as the cooling medium, which can reduce the motor temperature from 337°C to 147°C under natural cooling conditions, achieving high cooling efficiency.…”
