Description

Technical Field

[0001] This utility model relates to the field of flywheel energy storage technology, and in particular to a heat dissipation system for flywheel energy storage. Background Technology

[0002] Flywheel energy storage refers to an energy storage method that uses an electric motor to drive a flywheel to rotate at high speed, and then uses the flywheel to drive a generator to generate electricity when needed. Its technical characteristics are high power density and long life. The flywheel body is the core component of the flywheel energy storage system. Its function is to strive to increase the rotor's limiting angular velocity, reduce the rotor's weight, and maximize the energy storage capacity of the flywheel energy storage system.

[0003] A flywheel energy storage system is an electromechanical energy conversion energy storage device that overcomes the limitations of chemical batteries by using physical methods to store energy. It achieves energy storage through a bidirectional motor that reverses electric / generator operation, converting and storing electrical energy between the mechanical kinetic energy of a high-speed rotating flywheel. This is achieved through frequency regulation, rectification, constant voltage, and interfaces with different types of loads. During energy storage, electrical energy is converted by a power converter to drive the motor, which in turn drives the flywheel to accelerate. The flywheel stores energy in the form of kinetic energy, completing the energy storage process from electrical to mechanical energy conversion. The energy is stored in the high-speed rotating flywheel. Afterward, the motor maintains a constant speed until it receives a control signal to release energy. During energy release, the high-speed rotating flywheel drives the motor to generate electricity, which is then output by the power converter with current and voltage suitable for the load, completing the energy release process from mechanical to electrical energy conversion. The entire flywheel energy storage system realizes the input, storage, and output of electrical energy.

[0004] Existing flywheel energy storage devices generate a lot of heat during operation, and traditional heat dissipation methods generally rely on the outer surface of the flywheel energy storage device for heat dissipation, which has low heat dissipation efficiency and will affect the stability of the flywheel energy storage device during long-term operation.
