Problems solved by technology
[0005] There are two problems in the above method: on the one hand, during the operation of the flywheel, the magnetic bearing and the motor stator will also generate a certain amount of heat, which will lead to a decrease in equipment reliability or failure during long-term operation; on the other hand , the rotor adopts a hollow structure, which is difficult to manufacture, requires high structural precision, and the heat dissipation area of the flywheel is too limited by the heat dissipation disc
[0006] To sum up, the heat dissipation of the existing flywheel energy storage device is relatively partial, and the heat dissipation effect cannot meet the requirements

The invention relates to a flywheel energy storage and heat dissipation system. Comprising an upper shell, a lower shell and a water cooling machine. The upper shell and the lower shell are connected in an involution manner; a flywheel body, a flywheel rotating shaft, an upper radial magnetic bearing, a lower radial magnetic bearing and a motor are installed in a cavity formed by the upper shell and the lower shell. The flywheel body is installed on the flywheel rotating shaft, and the upper radial magnetic bearing and the lower radial magnetic bearing are installed at the upper end and the lower end of the flywheel rotating shaft respectively. A spiral upper cooling water channel is mounted in the upper shell and extends in the upper shell; a spiral lower cooling water channel is mounted in the lower shell and extends in the lower shell; the water cooling machine provides cooling liquid for the upper cooling water channel and the lower cooling water channel. Along with the extension of the upper cooling water channel in the upper shell and the extension of the lower cooling water channel in the lower shell, the upper cooling water channel and the lower cooling water channel can dissipate heat of the upper radial magnetic bearing, the flywheel body, the lower radial magnetic bearing and the motor. The LED lamp is wide in heat dissipation range and good in heat dissipation effect.
Description
technical field [0001] The invention belongs to the technical field of heat dissipation of energy storage equipment, and in particular relates to a flywheel energy storage and heat dissipation system. Background technique [0002] Since the development of flywheel energy storage in the middle of the 20th century, it has more than 50 years of research, development and application history. Flywheel energy storage is to store energy in the high-speed rotating flywheel rotor, and can realize the bidirectional conversion of electric energy and kinetic energy. Flywheel energy storage technology is currently mainly used in engineering and technical fields such as uninterruptible power supply, power quality regulation, energy recovery and regeneration, and distributed energy power smoothing. [0003] The power of flywheel energy storage motor and converter is 100-3000kW. The lost electrical energy is usually converted into heat. In addition, although the flywheel rotor is in a vac...
