Description

Technical Field

[0001] This invention belongs to the field of generator technology, and specifically discloses a high-power AC generator for data centers. Background Technology

[0002] High-power AC generators in data centers are mostly three-phase synchronous generators, with power ratings typically ranging from 750 to 3000 kVA, serving as emergency backup power to ensure continuous power supply. Current technology features a generator stator fixed to a support frame, with the rotor rotating at high speed (1500 / 1800 rpm) to generate a rotating magnetic field that cuts the stator windings to output high-voltage AC power; some models employ water-cooled windings to improve heat dissipation. The entire unit emphasizes high reliability, rapid transient response, and low vibration to meet the stringent requirements of uninterrupted power supply in data centers.

[0003] In the current technology, high-power AC generators in data centers generally use water cooling but not air cooling, resulting in a single cooling method and reduced cooling effect.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-10The diagram illustrates a high-power AC generator for a data center, comprising a rotating shaft 1. The rotating shaft 1 is a core rotating support component, typically forged from high-strength alloy steel, possessing excellent bending and fatigue resistance. One end of the shaft 1 has a spline structure for connection to a prime mover or coupling to transmit torque. The rotor core and rotor support are mounted on the shaft, rotating at high speed to generate a rotating magnetic field. The shaft's interior can be designed as a hollow structure for introducing lubricating oil or coolant to lubricate and cool the bearings and rotor, ensuring the stability and reliability of the high-power generator under long-term full-load operation. An outer casing 2 is rotatably connected to the outside of the shaft 1. The outer shell 2 protects the internal structure. A cooling mechanism 3 is installed on the outside of the outer shell 2 to improve the generator's heat dissipation capacity. A dust removal mechanism 4 is installed on the outside of the rotating shaft 1 to prevent dust from clogging the heat dissipation holes. A bracket 5 is rotatably connected to the outside of the rotating shaft 1, and a stator core 6 is fixedly connected to the outside of the bracket 5. The stator core 6 is the core static magnetic circuit component of the generator, typically made of stacked high-permeability, low-loss silicon steel sheets, forming a ring shape and fixed to the frame. Its main function is to provide a low-resistivity magnetic circuit channel for the stator windings, interacting with the rotating rotor magnetic field to induce high-voltage alternating current in the stator windings. Structurally, the inner circumference of the core has evenly distributed slots for housing the stator windings, and the outer flange connects to the frame for mechanical fixation and heat dissipation. The laminated structure effectively suppresses eddy current losses. Combined with the winding cooling design, it ensures the high efficiency and stability of the high-power generator under long-term full-load operation. The rotor core 7 is located inside the bracket 5. The rotor core 7 is the core component of the high-power AC generator in the data center. It is typically made of laminated high-permeability, low-loss silicon steel sheets, and is cylindrical in shape. It is fitted onto the shaft and fixed to the rotor bracket. Its main function is to provide a magnetic circuit path for the excitation winding, forming a stable rotating magnetic field when the rotor rotates at high speed, cutting the stator winding to induce AC current. Structurally, slots are cut on the surface or inside of the core to accommodate the excitation winding. Lead-out rods on both sides are used to connect to the excitation power supply, providing excitation current to the winding. This laminated structure effectively suppresses eddy current losses. Combined with the overall dynamic balance design of the rotor, it ensures the stability and efficiency of the high-power generator under long-term high-speed operation. The shaft 1, outer casing 2, bracket 5, stator core 6, and rotor core 7 together form a high-power AC generator.

[0022] Cooling mechanism 3 includes a liquid storage box 301, which provides a liquid storage space. One end of the liquid storage box 301 is fixedly connected to one end of the outer shell 2, and the other end of the outer shell 2 is fixedly connected to a protective shell 313. The protective shell 313 provides an installation position and protection function. A pump head 302 is fixedly connected inside the protective shell 313. After the input shaft of the pump head 302 rotates, it can pump and deliver liquid. The end of the rotating shaft 1 away from the liquid storage box 301 is fixedly connected to the input shaft of the pump head 302, which connects to the pump blades. A liquid cooling pipe 303 is fixedly connected inside the outer shell 2. The liquid cooling pipe 303 is wound inside the outer shell 2, thereby enabling liquid cooling heat dissipation for the internal structure of the outer shell 2. Since it can directly provide liquid cooling heat dissipation for the internal structure of the outer shell 2, from To improve heat dissipation, a drain pipe 304 is fixedly connected to the output end of the pump head 302. The drain pipe 304 discharges liquid into the interior of the rotating shaft 1. A suction pipe 305 is fixedly connected to the input end of the pump head 302. The suction pipe 305 directs the liquid discharged from the output end of the drain pipe 304 into the interior of the liquid storage box 301. The other end of the suction pipe 305 is fixedly connected to the outside of the liquid storage box 301. A liquid-passing sleeve 306 is rotatably connected to the outer end of the rotating shaft 1 away from the liquid storage box 301. The liquid-passing sleeve 306 does not interfere with the rotation of the rotating shaft 1. The end of the drain pipe 304 away from the pump head 302 is fixedly connected to the outer wall of the liquid-passing sleeve 306. The outer side of the rotating shaft 1 is located inside the liquid-passing sleeve 306. Multiple liquid passage holes 307 are provided at one end of the shaft 1, allowing liquid to flow into the hollow groove 308. A hollow groove 308 is provided inside the shaft 1. A drain pipe 304 is connected to the outside of a liquid passage sleeve 306, allowing liquid to first be transferred to the inside of the liquid passage sleeve 306, and then enter the hollow groove 308 inside the shaft 1 through the liquid passage holes 307. Since the shaft 1 rotates while the drain pipe 304 is fixed to the outside of the liquid passage sleeve 306, the liquid passage sleeve 306 prevents motion interference between the drain pipe 304 and the shaft 1. Liquid flowing into the hollow groove 308 provides heat dissipation, further enhancing heat dissipation efficiency. Multiple liquid passage holes 307 are provided at the outer end of the shaft 1 furthest from the liquid passage holes 307. A drain hole 309 allows liquid inside the hollow groove 308 to flow into the liquid storage box 301. Fans 310 are fixedly connected to both ends of the rotating shaft 1. When the fans 310 rotate with the shaft 1, they generate air convection, thus achieving air cooling. Combined with water cooling, this improves the heat dissipation effect. An agitator 311 is fixedly connected to the outside of the rotating shaft 1 inside the liquid storage box 301. The agitator 311, when rotating, stirs the liquid inside the liquid storage box 301, thereby accelerating the heat dissipation of the liquid inside the liquid storage box 301. A shock-absorbing spring 8 is fixedly connected to the outside of the rotating shaft 1 near the liquid-passing sleeve 306. The shock-absorbing spring 8 has four main functions: first, vibration reduction and noise reduction.It effectively absorbs radial and axial vibrations caused by electromagnetic force, unbalanced mass, or prime mover impact during the rotation of shaft 1, preventing amplified vibrations from being transmitted to the base and foundation, thereby reducing the overall noise level of the machine; secondly, it buffers impacts, mitigating instantaneous impact loads generated during generator startup, shutdown, or sudden load changes, preventing fatigue damage to shaft 1, bearings, or couplings due to stress concentration; thirdly, it compensates for displacement, allowing shaft 1 to undergo minor displacements due to thermal expansion or alignment errors, avoiding additional stress from rigid connections and improving the stability of the shaft system; fourthly, it protects electrical components by blocking the transmission of vibration to precision electrical components such as stator windings and excitation systems, preventing insulation wear and loose wiring caused by vibration. In case of electrical faults such as vibration, the other end of the shock-absorbing spring 8 is fixedly connected to the inner wall of the outer shell 2. Liquid passage pipes 312 are fixedly connected to both the upper and lower ends of the liquid storage box 301. The liquid passage pipes 312 facilitate liquid injection and drainage. A sealing cap is threaded onto the end of the liquid passage pipe 312 away from the liquid storage box 301 to prevent blockage. One end of the liquid cooling pipe 303 is fixedly connected to the outside of the liquid passage sleeve 306, and the other end is fixedly connected to the inside of the liquid storage box 301. Multiple heat dissipation fins 314 are fixedly connected to the outer side of the outer shell 2 away from the liquid storage box 301. The heat dissipation fins 314 conduct heat, and one section of the liquid cooling pipe 303 is fixedly connected between the multiple heat dissipation fins 314. When the generator operates, the shaft 1 rotates, which drives the input shaft of the pump head 302 to rotate. After the input shaft of the pump head 302 rotates, the input end of the pump head 302 draws liquid in through the suction pipe 305 and discharges it through the output end of the pump head 302. The liquid then enters the liquid sleeve 306 through the drain pipe 304, enters the hollow groove 308 through the liquid passage hole 307, and is discharged into the liquid storage box 301 through the drain hole 309. A portion of the liquid enters the liquid cooling pipe 303 and then into the liquid storage box 301. One section of the liquid cooling pipe 303 passes through multiple heat dissipation fins 314, where heat is first dissipated through heat conduction. When the shaft 1 rotates, it drives the stirring blade 3... 11 rotates, and the stirring blade 311 rotates to agitate the liquid inside the liquid storage box 301, thereby agitating and dissipating heat. At the same time, when the rotating shaft 1 rotates, it can drive the two fans 310 to rotate, thereby forming a convective airflow, which can achieve airflow cooling and liquid cooling, and directly act on the internal structure of the generator, thereby improving the heat dissipation efficiency. When replacing the liquid inside the liquid storage box 301, first unscrew the threaded cap of the lower liquid passage pipe 312 to drain the liquid inside the liquid storage box 301, cover the threaded cap of the lower liquid passage pipe 312, then unscrew the threaded cap of the upper liquid passage pipe 312, inject the liquid into the liquid storage box 301, and then cover the threaded cap of the upper liquid passage pipe 312.

[0023] The dust removal mechanism 4 includes two fixed rings 401, which provide installation positions. The inner sides of the two fixed rings 401 are fixedly connected to the outer sides of the rotating shaft 1. Multiple fixed posts 402 are fixedly connected to the outer sides of the fixed rings 401, providing installation positions and installation space. A retaining spring 403 is provided inside the fixed post 402, and a limit plate 404 is slidably connected inside the fixed post 402. The limit plate 404 has a limiting function, and a movable post 405 is fixedly connected to the end of the limit plate 404 away from the retaining spring 403. The movable column 405 serves a connecting function. A cleaning brush 406 is fixedly connected to the end of the movable column 405 furthest from the limiting plate 404. The retaining spring 403 provides a force to the limiting plate 404 away from the fixing ring 401, transmitting this force to the movable column 405. This force is then transmitted to the cleaning brush 406, causing it to press firmly against the inner wall of the outer casing 2, thus removing dust. When the fan 310 rotates, the resulting airflow blows away the scraped dust. The retaining spring 403... One end is fixedly connected to the inside of the fixed post 402, and the other end of the clamping spring 403 is fixedly connected to the end of the limiting plate 404 away from the movable post 405. The cleaning brush 406 contacts the inner wall of the outer shell 2. The movable post 405 passes through the end of the fixed post 402 away from the fixed ring 401. The inside of the hollow groove 308 is connected to the inside of the drain hole 309. The inside of the liquid passage hole 307 is connected to the inside of the hollow groove 308. When the rotating shaft 1 rotates, it can drive the fixed ring 401 to rotate. After the fixed ring 401 rotates, it can drive the limiting plate 404 and the movable post 405 to rotate. The rotating column 405 rotates, and the pressing spring 403 uses its own reaction force to exert an outward force on the limiting plate 404, the rotating column 405 and the cleaning brush 406, thereby making the cleaning brush 406 stick tightly to the inner wall of the outer casing 2. When the cleaning brush 406 rotates, it can wipe the dust off the inner wall of the outer casing 2. At the same time, when the rotating shaft 1 rotates, it drives the fan 310 to rotate, thereby generating convective airflow, which can blow away the dust wiped off by the cleaning brush 406, thus preventing dust from clogging the ventilation holes of the outer casing 2.

[0024] Working principle: When the generator is running, the rotating shaft 1 rotates, which drives the input shaft of the pump head 302 to rotate. After the input shaft of the pump head 302 rotates, the input end of the pump head 302 draws liquid in through the suction pipe 305 and discharges it through the output end of the pump head 302. The liquid then enters the interior of the liquid sleeve 306 through the drain pipe 304, enters the interior of the hollow groove 308 through the liquid passage hole 307, and is discharged into the interior of the liquid storage box 301 through the drain hole 309. A portion of the liquid enters the liquid cooling pipe 303 and then enters the interior of the liquid storage box 301. One section of the liquid cooling pipe 303 passes through multiple heat dissipation fins 314. Heat is first dissipated through the heat conduction of the heat dissipation fins 314. When the rotating shaft 1 rotates, it drives the agitator... The stirring blade 311 rotates, which agitates the liquid inside the liquid storage box 301, thereby agitating and dissipating heat. At the same time, when the rotating shaft 1 rotates, it drives the two fans 310 to rotate, thereby forming a convective airflow, which can achieve wind-powered heat dissipation and liquid-cooled heat dissipation, and directly act on the internal structure of the generator, thereby improving the heat dissipation efficiency. When replacing the liquid inside the liquid storage box 301, first unscrew the threaded cap of the lower liquid passage pipe 312 to drain the liquid inside the liquid storage box 301, then cover the threaded cap of the lower liquid passage pipe 312, then unscrew the threaded cap of the upper liquid passage pipe 312, and inject the liquid into the liquid storage box 301, and then cover the threaded cap of the upper liquid passage pipe 312. When the rotating shaft 1 rotates, it drives the fixed ring 401 to rotate. The rotation of the fixed ring 401 drives the limiting plate 404 and the movable column 405 to rotate. At the same time, the clamping spring 403 can use its own reaction force to exert an outward force on the limiting plate 404, the movable column 405 and the cleaning brush 406, so that the cleaning brush 406 can stick tightly to the inner wall of the outer shell 2. When the cleaning brush 406 rotates, it can wipe the dust off the inner wall of the outer shell 2. At the same time, when the rotating shaft 1 rotates, it drives the fan 310 to rotate, thereby generating convective airflow, which can blow away the dust wiped off by the cleaning brush 406, thus preventing dust from clogging the ventilation holes of the outer shell 2.
