Abstract

The utility model discloses a flywheel energy storing device capable of cooling a rotator. The flywheel energy storing device comprises an outer shell, a stator arranged in the middle of the outer shell, and rotators arranged on the two sides of the stator, wherein the rotators are fixedly connected by a rotating shaft of a heat pipe structure; the two ends of the rotating shaft are supported on an upper cover plate and a lower cover plate of the outer shell by bearings; the outside of the bearing is axially fixed by a pressing cover; and the end surface of the rotating shaft, the outside of the bearing and the inside surface of the pressing cover form a sealed cavity. In the utility model, the rotating shaft is manufactured into the heat pipe structure; the heat can be rapidly transmitted to the two ends, namely radiating ends, of the rotating shaft by the middle section, namely a heat absorbing end, of the rotating shaft; and then the radiating ends of the rotating shaft are cooled so as to output the heat of the rotators and ensure the effective long time operation of a system.

Description

But a kind of energy accumulation device for fly wheel of cooled rotor
Technical field
The utility model relates to flywheel energy storage system, especially relates to a kind of heat that can effectively derive rotor, but the energy accumulation device for fly wheel of the cooled rotor of the effective long-term operation of assurance system.
Background technology
The flywheel energy storage principle generally is to rely on the rotation of driven by motor flywheel, stores and convert electrical energy into mechanical energy, when needed, utilizes the deceleration of flywheel to convert mechanical energy into electric energy.Flywheel energy storage system has multiple method for designing according to different requirement.Flywheel energy storage system is generally supported by magnetic bearing, particularly in the high speed flywheel energy-storage system.In order to reduce air drag and energy loss, flywheel generally is placed in the vacuum chamber.Have the disc type high speed flywheel energy-storage system of round trip flight wheel (rotor), single stator, stator discs is positioned between two flywheels (rotor), and two flywheel middle parts are fixed together, and the axle of flywheel both sides is by bearings.In order to guarantee the vacuum degree of vacuum chamber, axle and bearing all are placed in the vacuum chamber.The flywheel high speed rotating works long hours and can generate heat, because flywheel is in vacuum environment, to work, and the method for traditional ventilation cooled rotor, inapplicable in vacuum environment, so the heat that flywheel produces is derived very difficulty.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of heat that can effectively derive rotor, but the energy accumulation device for fly wheel of the cooled rotor of the effective long-term operation of assurance system.
But the energy accumulation device for fly wheel of the cooled rotor that the utility model proposes comprises shell, is located at the middle stator of shell, is located at the rotor of stator both sides.This rotor is fixedly connected by the rotating shaft of a heat pipe structure, and on the upper and lower cover plate of shell, the outside of bearing is by the gland axial restraint by bearings at the rotating shaft two ends, and rotating shaft end face, the bearing outside and gland medial surface form a sealed hollow.
Wherein, be provided with coolant in the said sealed hollow.
Described coolant can be an air, also can be cooling fluid.
The utility model is made heat pipe structure with rotating shaft, promptly makes hollow axle, also is provided with a tube core in its inner chamber.Rotor high-speed rotates the heat that produces, and can be delivered to the two ends-release end of heat of rotating shaft through the stage casing-heat absorbing end of rotating shaft fast, and then the release end of heat of countershaft cools off.In the cavity of rotating shaft two ends, inject the cold oil of circulation, can effectively derive the heat of rotor, guarantee effective long-term operation of system.Because the heat pipe structure heat transfer efficiency is high, takes air-cooled or other types of cooling, all can the heat of rotor effectively be spread out of.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the cut-away illustration of the utility model preferred embodiment.
Embodiment
As shown in Figure 1, but the energy accumulation device for fly wheel of the cooled rotor that the utility model proposes, and it comprises shell 1, is located at the middle stator 2 of shell, is located at the rotor 3 of stator both sides.This rotor 3 is fixedly connected by the rotating shaft 4 of a heat pipe structure, and the rotating shaft two ends are supported in by bearing 5 on the upper and lower cover plate of shell 1, and the outside of bearing is by gland 6 axial restraints, and rotating shaft end face, the bearing outside and gland medial surface form a sealed hollow 8.In the present embodiment, the rotating shaft 4 of heat pipe structure also is provided with in one in its inner chamber and manages 7 for the hollow axle of both ends of the surface sealing.Rotor 3 adopts interference fit to connect with being connected of rotating shaft 4, also can adopt other connecting mode, as, key connection, spline connect or are threaded or the like.Be provided with coolant in the sealed hollow 8.This coolant is an air, also can be cooling fluid.
The utility model is made heat pipe structure with rotating shaft, promptly makes hollow axle, and rotating shaft also is provided with an interior pipe as the heat pipe tube core as the shell of heat pipe in its inner chamber.Rotor high-speed rotates the heat that produces, and can be delivered to the two ends-release end of heat of rotating shaft through the stage casing-heat absorbing end of rotating shaft fast, and then the release end of heat of countershaft cools off.In the cavity of rotating shaft two ends, inject the cold oil of circulation, can effectively derive the heat of rotor, guarantee effective long-term operation of system.Because the heat pipe structure heat transfer efficiency is high, takes air-cooled or other types of cooling, all can the heat of rotor effectively be spread out of.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
