The invention discloses a cooling device for heat conduction oil in a hollow shaft of a motor rotor and a flywheel energy storage motor, wherein the cooling device includes a motor mandrel, a sealed oil tank, an oil delivery pipe and an electric drive oil pump, and the motor mandrel defines a hollow shaft extending along the axial direction. The lower end of the hollow cavity is an open end and the upper end is a closed end; the sealed oil tank is located at the lower end of the motor mandrel, and the sealed oil tank is connected to the lower end of the motor mandrel by suspension and sealing; the oil delivery pipe is arranged in the hollow cavity, and the lower end of the oil delivery pipe extends into the oil chamber The middle and the upper end extend into the upper part of the hollow cavity; the upper end of the oil delivery pipe is connected with a fuel injection pipe with a nozzle. The tangential velocity of the fuel injection at the nozzle is the same as the tangential velocity of the inner wall rotation of the hollow cavity; the electric drive oil pump drives the oil in the sealed oil tank to be sprayed out from the nozzle through the oil delivery pipe and the fuel injection pipe in sequence. The cooling device can effectively cool the motor mandrel, prevent the motor rotor from overheating, and prolong the service life of the energy storage motor.
Description
technical field [0001] The invention relates to the technical field of a motor rotor cooling device for a flywheel energy storage system, in particular to a heat transfer oil cooling device in a hollow shaft of a motor rotor and a flywheel energy storage motor. Background technique [0002] Flywheel energy storage is an advanced physical energy storage technology with high power density, rapid response, long life, and friendly environmental characteristics. In order to improve the energy storage density and power density, the flywheel usually operates at a very high speed (over 10,000rpm). The motor has a high power density and a high calorific value, and the heat is not easy to dissipate in a vacuum environment. [0003] A large amount of heat on the motor is not dissipated, which will directly affect the operation of the flywheel energy storage device, and will also reduce the service life and energy efficiency of the motor. Severe heat will cause damage to the motor. The...
