The invention discloses an eVTOL aircraft lift electric drive cooling system which comprises a motor arm, the front end of the motor arm is connected with a motor arm front fairing, the lower portion of the motor arm front fairing is connected with a heat dissipation water tank, the rear end of the heat dissipation water tank is connected with a controller and a lift motor through a liquid cooling assembly, and the lift motor and the controller are installed in the motor arm. The appearance of the heat dissipation water tank and the motor arm are of a conformal structure, and the outer surface of the heat dissipation water tank is of a curved surface structure. The system adopts the radiator integrated with the motor arm structure, the radiator does not need to be arranged outside the aircraft structure, a cooling air duct does not need to be formed either, and the resistance of the aircraft is reduced. And the integrated heat dissipation water tank is cooled by external incoming flow, so that the cooling requirement of the aircraft is met at an acceptable cost.

    本发明公开了一种eVTOL飞机升力电驱冷却系统,包括电机臂,所述电机臂前端连接电机臂前整流罩,所述电机臂前整流罩下方连接散热水箱,所述散热水箱后端通过液冷组件连接控制器、升力电机,所述升力电机和控制器安装于电机臂内部,所述散热水箱的外形与电机臂采用共形结构,所述散热水箱的外表面为曲面结构。本系统采用与电机臂结构一体的散热器,不需要在飞机结构外部布置散热器,也不需要开冷却风道,降低了飞机的阻力。一体化的散热水箱接受外部来流冷却,以可接受的代价满足了飞机的冷却要求。
