Description

Technical Field

[0001] The invention relates to the technical field of synchronous phase modulators, and in particular to a synchronous phase modulator cooling device which is convenient for stator assembly and has multi-path heat dissipation. Background Art

[0002] The synchronous phase modulator is a special synchronous motor, which mainly consists of two parts: the stator and the rotor. The stator part includes the stator core and the stator winding. The stator winding usually adopts a three-phase winding to generate a rotating magnetic field. The rotor part includes the rotor core and the excitation winding. The excitation winding is passed with a DC current to generate a magnetic field. In addition, the synchronous phase modulator is also equipped with an excitation system to control the magnitude and direction of the excitation current to achieve the regulation of reactive power. There are also some auxiliary equipment, such as cooling systems, bearings, etc., to ensure the normal operation of the motor.

[0003] However, the synchronous phase modulator generates a huge amount of heat during operation. This heat mainly comes from the loss caused by the conversion of electromagnetic energy in the process of changing the reactive power output by the excitation current; the heat generated by the friction between the mechanical parts when the rotating parts are running; and the heat generated by the eddy current loss and hysteresis loss of the stator and rotor core in the alternating magnetic field. If this heat is not transferred in time, it will not only reduce the performance and operating efficiency of the synchronous phase modulator, but may even cause irreversible physical damage to the synchronous phase modulator, ultimately affecting the life of the motor.

[0004] In addition, as the size of synchronous phase modulators continues to expand, their device structure is becoming increasingly complex. At present, the main methods for fixing stator core laminations are welding, riveting and adhesives, but each of the three methods has its own shortcomings, and the specific implementation is somewhat complex. In this case, how to reduce the assembly complexity of the device, speed up the assembly process of the motor, and improve the production efficiency of the device has become a key problem that needs to be overcome urgently.

[0005] In summary, in order to ensure the working efficiency of the motor, maintain the safety and stability, and enhance the convenience of assembly, a complete cooling system and a suitable assembly mechanism are indispensable key elements;

[0006] After searching, Chinese patent number CN118399674A discloses a heat dissipation mechanism for a permanent magnet synchronous motor rotor. In this scheme, only the top of the evaporation end is an evaporation chamber, and the rest is a heat transfer material, which is prone to uneven thermal stress, thereby causing mechanical damage to the stator; the condensation end only uses natural cooling and forced air cooling, and the heat dissipation capacity is limited. In addition, the forced air cooling structure uses more gear transmission structures, resulting in large friction losses;

[0007] And the Chinese patent number CN117458747A discloses a dual-coupled cooling system for the stator core of a synchronous phase regulator for ultra-high voltage power transmission. This solution inserts honeycomb heat sinks into the gaps between the stator core laminations, and still leaves a certain ventilation gap, which makes the spacing between the core laminations too large, resulting in an increase in the magnetic resistance of the magnetic circuit, thereby reducing the power factor and efficiency of the motor. In addition, this solution uses uneven installation of the stator core laminations, which will lead to uneven magnetic field distribution, and further lead to unstable torque, reduced efficiency and other consequences. Secondly, it may also cause increased vibration and noise of the motor, affecting the normal operation and working environment of the equipment;

[0037] The cooling mechanism includes an outer cover 15, and the two outer covers 15 are respectively fixedly connected to the front and rear sides of the condensation box 12 by bolts. A plurality of first cooling fans 16 are inlaid on the top of the outer cover 15, and a second cooling fan 17 is inlaid on the side of the outer cover 15. A plurality of S-shaped grooves 18 are provided on the front and rear sides of the condensation box 12, and an S-shaped tube 19 is embedded in the S-shaped groove 18. A coolant inlet pipe 20 and a coolant outlet pipe 21 are respectively fixedly connected at both ends of the S-shaped tube 19. The first cooling fan 16 can suck the ambient air of the motor into the outer cover 15 to be cooled by the coolant flowing in the S-shaped tube 19, and then the second cooling fan 17 discharges the cooled air to the environment where the motor is located, thereby achieving the purpose of reducing the ambient temperature of the motor.

[0038] A plurality of condensing fins 24 are fixedly connected to the front and rear side walls inside the condensing box 12, respectively. The plurality of condensing fins 24 are staggered with the two S-shaped condensing tubes 22. The condensing fins 24 are inclined. The condensing fins 24 are inclined from high to low from close to the inner wall of the condensing box 12 to the side away from the inner wall of the condensing box 12.

[0039] The front and rear edges of the top and bottom of the chip heat dissipation shell 3 are respectively fixedly connected with a connecting and fastening block 6, the connecting and fastening block 6 consists of a left connecting block 61 and a right connecting block 62, the chip heat dissipation shell 3 consists of a left half shell 31 and a right half shell 32, the left connecting block 61 is fixedly connected to the left half shell 31, the right connecting block 62 is fixedly connected to the right half shell 32, the left connecting block 61 and the right connecting block 62 are fixedly connected by bolts, the left half shell 31 and the right half shell 32 are fixedly connected by the connecting and fastening block 6, and the chip heat dissipation shell 3 is divided into two symmetrical parts, including the connecting and fastening block 6 on the surface of the chip heat dissipation shell 3, the steam pipe connecting pipe 4 and the return pipe connecting pipe 5 are all divided into two symmetrical parts for easy disassembly and installation.

[0040] A first flange 311 is fixedly connected to one side of the left half shell 31 close to the right half shell 32, and a first groove 321 is provided on one side of the right half shell 32 close to the left half shell 31. The first flange 311 is adapted to be located inside the first groove 321, and the phase change medium cavity 8 is located on the inner side of the first flange 311 and the first groove 321. When assembling the chip heat dissipation shell 3, the first flange 311 is inserted into the first groove 321 to improve the sealing between the left half shell 31 and the right half shell 32.

[0041] The steam pipe connecting pipe 4 is composed of a left half pipe 41 and a right half pipe 42, and the left half pipe 41 and the right half pipe 42 are respectively fixedly connected to the left half shell 31 and the right half shell 32, and the left half pipe 41 and the right half pipe 42 are fixedly connected by bolts. The side of the left half pipe 41 close to the right half pipe 42 is fixedly connected with a second flange 411, and the side of the right half pipe 42 close to the left half pipe 41 is provided with a second groove 421, and the second flange 411 is adapted to be located inside the second groove 421. When assembling the steam pipe connecting pipe 4, the second flange 411 is inserted into the second groove 421 to improve the sealing between the left half pipe 41 and the right half pipe 42. The return pipe connecting pipe 5 has the same structure as the steam pipe connecting pipe 4, and is also divided into two symmetrical parts and processed with flanges and grooves to improve the sealing. Therefore, the structure of the return pipe connecting pipe 5 will not be excessively described here.

[0042] The front side of the connecting and fastening block 6 is provided with an assembly hole 7, and two or more chip-mounted heat dissipation shells 3 can be installed at the same time. When installing adjacent chip-mounted heat dissipation shells 3, bolts can be passed through the assembly hole 7 to fix the adjacent connecting and fastening blocks 6 on the two chip-mounted heat dissipation shells 3 together.

[0043] Two heat dissipation baffles 11 distributed front and back are fixedly connected to the inner wall of the sheet-mounted heat dissipation shell 3. The stator core 2 and the heat transfer fins 9 are both located between the two heat dissipation baffles 11. The thickness of the heat dissipation baffles 11 is half of the thickness of the heat transfer fins 9. Since the thickness of the heat dissipation baffles 11 is only half of the thickness of the heat transfer fins 9, when two or more sheet-mounted heat dissipation shells 3 are installed, the two heat dissipation baffles 11 between the two sheet-mounted heat dissipation shells 3 are fitted together to be equivalent to a heat transfer fin 9. In this way, the spacing between the last stator core 2 of the first sheet-mounted heat dissipation shell 3 and the first stator core 2 of the second sheet-mounted heat dissipation shell 3 is still the thickness of a heat transfer fin 9, thereby ensuring that the spacing between all stator core 2 laminations is the same, so as to achieve the purpose of uniform distribution of the magnetic field, which can reduce motor jitter and noise, and improve efficiency.

[0044] Working principle:

[0045] During assembly, the left half shell 31 and the right half shell 32 can be mounted on the stator core 2 and fixed by means of the left connecting block 61 and the right connecting block 62 with bolts, and the multiple heat transfer fins 9 on the inner side of the heat dissipation shell 3 are inserted into the gap of the stator core 2. During heat dissipation, the ventilation holes 10 inside the heat transfer fins 9 can dissipate the heat generated by the rotor 1 and the stator core 2 to the outside of the heat dissipation shell 3. At the same time, the phase change medium cavity 8, the condensation box 12, the steam pipe 13 and the return pipe 14 form a phase change medium circulation passage, and the heat transfer fins 9 transfer heat. The liquid phase change medium absorbs heat in the phase change medium cavity 8 and evaporates into gas, and then enters the condensation box 12 through the steam pipe 13. The gaseous phase change medium cools down and condenses in the condensation box 12 to form a liquid phase change medium, and then flows back to the phase change medium cavity 8 through the return pipe 14 for circulation and heat dissipation.

[0046] During this period, the first cooling fan 16 and the second cooling fan 17 in the cooling mechanism are started, the outer cover 15 sucks air in the working environment into the outer cover 15, and then discharges it through the second cooling fan 17, and the outer cover 15 has an S-shaped tube 19 embedded in the outer wall of the condensation box 12, and coolant flows in the S-shaped tube 19, and the coolant is circulated by the coolant inflow tube 20 and the coolant outflow tube 21. The first cooling fan 16 sucks ambient air into the outer cover 15 and contacts the S-shaped tube 19 to be cooled, and then the cooled air is blown back into the ambient air through the second cooling fan 17. This will lower the temperature of the environment in which the motor is located. At the same time, the coolant in the S-shaped tube 19 will also pass through the condenser box 12 to cool the condenser fins 24 inside it. The gaseous phase change medium entering the condenser box 12 from the steam pipe 13 will enter the two air outlets 23 at the bottom of the gaseous phase change medium inflow tube 121, and then be discharged through the condenser fins 24 on the air outlets 23 and contact the condenser fins 24. After contacting the condenser fins 24, the steam will be condensed into liquid, and finally drip and gather together in the tapered flow channel 25 and return to the phase change medium cavity 8 through the reflux pipe 14 for recycling.
