Description

Technical Field

[0001] This application relates to the technical field of magnetically controlled reactors, and in particular to a noise reduction and cooling device for magnetically controlled reactors and magnetically controlled reactors. Background Technology

[0002] Magnetic control reactors are a new type of dynamic reactive power compensation device. Due to their low cost, small footprint, and maintenance-free operation, they are increasingly widely used in substations, wind farms, electrified railways, coal mines, and other fields. With the rapid advancement of urbanization in my country, urban electricity loads are increasing, and the cable penetration rate is rising. Consequently, power grid pollution is becoming increasingly prominent, and the demand for reactive power is growing, with large fluctuations.

[0003] Because magnetically controlled reactors utilize the principle of iron core saturation, they often have high noise levels. To reduce noise, sound-absorbing cotton is usually installed. However, magnetically controlled reactors generate a lot of heat during continuous operation, and the sound-absorbing cotton can easily cause poor heat dissipation, making it impossible to achieve both noise reduction and cooling. Summary of the Invention

[0004] In order to improve both noise reduction and cooling effects, this application provides a noise reduction and cooling device for a magnetically controlled reactor and a magnetically controlled reactor.

[0005] Firstly, the noise reduction and cooling device for the magnetically controlled reactor provided in this application adopts the following technical solution:

[0006] The noise reduction and cooling device for the magnetically controlled reactor includes a noise reduction and cooling mechanism installed on the cabinet, the noise reduction and cooling mechanism comprising:

[0007] The cooling plate is installed on the inner side wall of the cabinet and has a cooling cavity inside, and is equipped with multiple heat dissipation fins that extend through the cabinet to the outside of the cabinet.

[0008] Cooling components are used to introduce a cooling medium that flows into the cooling chamber for cooling purposes;

[0009] Sound-absorbing cotton is placed between the cooling plate and the inner wall of the cabinet and is used to eliminate noise.

[0010] By adopting the above technical solution, the cooling component is used to cool the cooling plate. At the same time, the heat on the cooling plate can also be dissipated through the heat sink, thereby greatly reducing the temperature of the cooling plate. The cooling plate can effectively cool the cabinet, while the sound-absorbing cotton can eliminate the noise generated inside the cabinet. Thus, cooling and noise reduction can be achieved simultaneously. The sound-absorbing cotton does not affect the cooling of the cooling plate, thus improving both the cooling and noise reduction effects.

[0011] Noise travels slower in liquids than in metals. Therefore, noise also slows down when passing through a cooling medium, allowing the cooling medium to achieve both cooling and noise reduction.

[0012] At the same time, the cooling also creates a pressure difference in the air inside the cabinet. The temperature at the cooling plate is low, which means the air pressure is low. This causes the hot air inside the cabinet to flow towards the cooling plate. Due to the direction of air flow, the noise generated inside the cabinet is also eliminated after moving towards the cooling plate and sound-absorbing cotton, thereby further improving the cooling and noise reduction effect.

[0013] Optionally, the cooling component includes:

[0014] A liquid storage tank, mounted on the cabinet, is filled with cooling medium;

[0015] The pump body is mounted on the liquid storage tank;

[0016] The inlet pipe and outlet pipe are respectively installed on the pump body and the storage tank, and the other end of each is connected to the cooling chamber. When the pump body is started, the cooling medium is added to the cooling chamber through the inlet pipe and flows back to the storage tank through the outlet pipe.

[0017] By adopting the above technical solution, the pump body starts, so that the cooling medium in the storage tank is input into the cooling chamber through the inlet pipe, and then the cooling medium flows back into the storage tank through the outlet pipe, thereby achieving the cooling of the cooling plate.

[0018] Optionally, the sound-absorbing cotton has multiple insertion holes for positioning and insertion into the heat sink, and the cooling plate is provided with multiple elastic components that pass through the sound-absorbing cotton and are detachably connected to the cabinet. The elastic components buffer and dampen the cooling plate under the action of elasticity.

[0019] By adopting the above technical solution, the heat sink is inserted and positioned in the sound-absorbing cotton, thereby connecting the sound-absorbing cotton, heat sink, and cooling plate together. This allows the sound-absorbing cotton to fit more tightly with the heat sink and cooling plate, maximizing the area of ​​the sound-absorbing cotton and improving its sound absorption effect. Furthermore, the elastic component enables the installation of the cooling plate, thus facilitating the installation of the sound-absorbing cotton, heat sink, and cooling plate. The elastic component also buffers the cooling plate, reducing the probability of the cooling plate vibrating when the cabinet vibrates, improving the cooling plate's cooling stability, and enhancing the cooling and sound absorption effect on the cabinet.

[0020] Optionally, the elastic component includes:

[0021] The positioning column is set on the inner side wall of the cabinet and slides through the cooling plate;

[0022] A spring is sleeved on a positioning post and presses against the cabinet and cooling plate for positioning. The sound-absorbing cotton has a clearance hole for the spring to pass through, and the area of ​​the sound-absorbing cotton is larger than the area of ​​the cooling plate, so as to provide a certain support for the cooling plate.

[0023] The positioning nut is threaded onto the positioning post and abuts against the cooling plate for positioning.

[0024] By adopting the above technical solution, multiple springs are respectively sleeved on multiple positioning posts, and the heat sink is inserted into multiple insertion holes on the sound-absorbing cotton to push the sound-absorbing cotton against the cooling plate. Then, multiple positioning posts are passed through the cooling plate, so that multiple springs pass through multiple clearance holes. Finally, positioning nuts are threaded onto the positioning posts for positioning, so that the springs press against the cooling plate and the cabinet for positioning, thereby realizing the installation and replacement of the cooling plate, heat sink, and sound-absorbing cotton.

[0025] Optionally, the cabinet has multiple air inlets evenly distributed on the side wall away from the cooling plate, and the cabinet is also equipped with a blower assembly, which includes:

[0026] A fan is installed inside the cabinet and located at the air inlet to blow air onto the cooling plate for cooling.

[0027] The filter plate is installed at the air inlet and is used to block dust from passing through.

[0028] By adopting the above technical solution, the fan starts, causing the hot air inside the cabinet to move to the cooling plate for cooling. This allows more heat to be dissipated through the heat sink, improving the cooling effect of the cabinet. Moreover, as the airflow velocity inside the cabinet towards the cooling plate increases, more noise is also moved to the cooling plate and sound-absorbing cotton for elimination. Therefore, the cooling and noise reduction effects can be improved simultaneously. The filter plate can filter impurities in the air, reducing the probability of impurities entering the cabinet and causing damage.

[0029] Optionally, the top of the cabinet has an installation hole and a detachable mounting plate that blocks the installation hole. Heat dissipation plate one and heat dissipation plate two are respectively inserted and installed on the cabinet at the air inlet and the cooling plate. The fan and the positioning column are installed on heat dissipation plate one and heat dissipation plate two. The cooling component is installed on the outside of the cabinet and passes through the installation hole to connect with the cooling plate.

[0030] By adopting the above technical solution, after removing the mounting plate, the positioning nut is turned and the cooling plate is moved so that the heat sink is separated from the cabinet. Then, heat sink one and heat sink two can be removed, and the fan, cooling components and spring components can be taken out and replaced. Compared with replacing them inside the cabinet, the convenience of replacement is greatly improved. Moreover, placing the cooling components on the outside of the cabinet maximizes the area of ​​the cooling plate and sound-absorbing cotton, and also reduces the risk of interference with electrical components inside the cabinet, thereby further improving the cooling and noise reduction effect.

[0031] Optionally, the heat sink is provided with a plurality of air inlet pipes communicating with a plurality of air inlets, and sound-absorbing cotton is fitted onto the plurality of air inlet pipes.

[0032] By adopting the above technical solution, multiple air inlet pipes are plugged into the sound-absorbing cotton. At the same time, the sound-absorbing cotton can eliminate noise inside the cabinet, thereby greatly reducing the noise inside the cabinet without interfering with the air entering the cabinet, and further improving the cooling and sound absorption effect.

[0033] Optionally, the liquid storage tank is equipped with a vacuuming mechanism, which includes:

[0034] A buoyancy plate floats on the liquid surface and has evenly distributed ventilation holes.

[0035] The telescopic component is installed on the buoyancy plate and connected to the liquid outlet pipe, allowing the liquid in the liquid outlet pipe to flow back to the storage tank located below the buoyancy plate;

[0036] A waterproof and breathable membrane is installed on the buoyancy plate, which blocks liquid from passing through the vents while allowing air to pass through.

[0037] The liquid inlet and air extraction assembly is used to add cooling medium to the liquid reservoir located below the buoyancy plate and extract air from the liquid reservoir located above the buoyancy plate.

[0038] By adopting the above technical solution, when the pump starts, the cooling medium flows back into the storage tank through the outlet pipe and the telescopic component. As the amount of cooling medium in the storage tank decreases, the liquid level drops, causing the buoyancy plate to move the telescopic component, thus reducing the flow space of the cooling medium. This ensures that the cooling medium fills the outlet pipe and telescopic component during its return flow, reducing the probability of noise caused by incomplete cooling. Simultaneously, the vacuum environment further reduces noise generation, thereby improving the cooling and noise reduction effects. After the amount of cooling medium in the storage tank decreases, the cooling medium can be added back into the storage tank through the inlet extraction component, and a vacuum can be created within the storage tank.

[0039] Optionally, the liquid inlet and air extraction assembly includes:

[0040] A liquid filling pipe is installed on the liquid storage tank and extends to the bottom wall inside the tank, and is equipped with a liquid inlet valve to control its opening and closing.

[0041] A vacuum pipe is located on the upper surface of the liquid storage tank and communicates with the inside of the liquid storage tank. The vacuum pipe is equipped with a vacuum valve for controlling its opening and closing and is used for detachable connection with a vacuum pump.

[0042] By adopting the above technical solution, the inlet valve is opened, and the cooling medium is added to the storage tank through the filling pipe. At the same time, the evacuation pipe is connected to the vacuum pump, and the vacuum pump is started to extract the air in the storage tank. As the cooling medium is added and the air is extracted, the air in the storage tank can move upward and pass through the waterproof and breathable membrane before being extracted, thereby reducing the risk of the cooling medium entering the vacuum pump. The process continues until the cooling medium is completely added, the inlet valve is closed, and then the vacuum pump continues to be started to extract all the air in the storage tank. Finally, the evacuation valve is closed, thus realizing the addition of cooling medium and vacuuming of the storage tank.

[0043] Secondly, the magnetically controlled reactor provided in this application adopts the following technical solution:

[0044] A magnetically controlled reactor, comprising a cabinet and a noise reduction and cooling device installed on the cabinet.

[0045] In summary, this application includes at least one of the following beneficial technical effects:

[0046] 1. The cooling plate is cooled by the cooling components and the heat sink dissipates heat, which greatly reduces the temperature of the cooling plate. The cooling plate can effectively cool the cabinet, while the sound-absorbing cotton can eliminate the noise generated inside the cabinet. Thus, cooling and noise reduction can be achieved at the same time. The sound-absorbing cotton does not affect the cooling of the cooling plate, so it improves the cooling and noise reduction effect at the same time.

[0047] 2. By cooling down the cabinet, a pressure difference is created inside, causing the hot air inside the cabinet to flow towards the cooling plate. Due to the direction of air flow, the noise generated inside the cabinet is also eliminated after moving towards the cooling plate and sound-absorbing cotton, thereby further improving the cooling and noise reduction effect.

[0048] 3. Since noise travels slower in liquids than in metals, the cooling medium also slows down the propagation of noise, allowing the cooling medium to achieve both cooling and noise reduction. Attached Figure Description

[0056] The following provides a further detailed description of this application.

[0057] This application discloses a noise reduction and cooling device for a magnetically controlled reactor.

[0058] Reference Figure 1 and Figure 2 The noise reduction and cooling device of the magnetically controlled reactor includes a noise reduction and cooling mechanism 3 installed on the cabinet 1. The noise reduction and cooling mechanism 3 is used to cool the cabinet 1 and eliminate noise generated inside the cabinet 1.

[0059] Reference Figure 2 and Figure 3The cabinet 1 has a cubic or cuboid structure. The top of the cabinet 1 has an open mounting hole 11 and a mounting plate 12 that seals the mounting hole 11 is fixedly installed by screws. Multiple air inlets 13 are vertically spaced on one side wall of the cabinet 1 to allow air to pass through. Heat dissipation plate 14 and heat dissipation plate 2 15 are vertically inserted and installed on the inner side wall of the cabinet 1 that communicates with the air inlets 13 and on the opposite inner side wall, respectively. A guide rail is fixedly installed inside the cabinet 1 by vertically inserting heat dissipation plate 14 and heat dissipation plate 2 15. Multiple air inlets 16 are fixedly installed on the side wall of heat dissipation plate 14 near the air inlet 13, corresponding to the multiple air inlets 13.

[0060] The cabinet 1 is also equipped with a blower assembly 2, which includes a fan 21 and a filter plate 22. The fan 21 is fixedly installed on the side wall of the heat sink 14 away from the air inlet pipe 16. When the fan 21 is activated, outside air is moved to the fan 21 through the air inlet 13 and the air inlet pipe 16, and then the air is blown towards the heat sink 15. Multiple air inlet pipes 16 are provided with sound-absorbing cotton 17. The sound-absorbing cotton 17 has multiple through holes that are inserted and positioned to cooperate with the multiple air inlet pipes 16, so that the sound-absorbing cotton 17 can be fitted onto the multiple air inlet pipes 16. The sound-absorbing cotton 17 can eliminate noise without interfering with the air passage. The filter plate 22 is fixedly installed on the outer wall of the cabinet 1 and covers multiple air inlets 13 to filter the air entering the air inlets 13.

[0061] Reference Figures 2-4 The noise reduction and cooling mechanism 3 includes a cooling plate 31 and noise reduction cotton 5. The cooling plate 31 is detachably mounted on the heat sink 15 via multiple elastic components 6. The air blown out by the fan 21 moves towards the cooling plate 31. The noise reduction cotton 5 is located between the cooling plate 31 and the heat sink 15, and the multiple elastic components 6 pass through the noise reduction cotton 5. The noise reduction cotton 5 has multiple clearance holes 51 for the elastic components 6 to pass through, thereby realizing the installation of the noise reduction cotton 5 between the cooling plate 31 and the heat sink 15. The multiple elastic components 6 are used to buffer and dampen the cooling plate 31 under the action of elasticity.

[0062] Multiple heat sinks 33 are fixedly installed on the side wall of the cooling plate 31 near the heat sink 15. The heat sinks 33 pass through the heat sink 15 and the cabinet 1 and extend outside the cabinet 1. The heat sinks 33 are used to dissipate the heat on the cooling plate 31 into the air. The sound-absorbing cotton 5 has multiple insertion holes 52 that are connected to the heat sinks 33, so that the sound-absorbing cotton 5 and the cooling plate 31 are connected to each other. The sound-absorbing cotton 5 can provide a certain support for the cooling plate 31. The sound-absorbing cotton 5 is used to eliminate noise. At the same time, the sound-absorbing cotton 5 extends to the outside of the cooling plate 31 and the heat sink 15, increasing the area of ​​the sound-absorbing cotton 5 and improving the noise elimination effect.

[0063] The elastic component 6 includes a positioning post 61, a spring 62, and a positioning nut 63. The positioning post 61 is fixedly installed on the heat dissipation plate 15 and slides through the cooling plate 31. The spring 62 is sleeved on the positioning post 61 and passes through the insertion hole 52. The positioning nut 63 is threadedly connected to the positioning post 61, and the two ends of the spring 62 press against the cooling plate 31 and the heat dissipation plate 15, so that the positioning nut 63 presses against the cooling plate 31 for positioning.

[0064] Reference Figure 2 , Figure 4 and Figure 5 The noise reduction and cooling mechanism 3 also includes a cooling component 4. The cooling component 4 is used to introduce a cooling medium that flows into the cooling cavity 32 for cooling. The cooling medium can cool the cooling plate 31. Since the speed of noise propagation in liquid is slower than that in metal, the cooling medium can also achieve a certain noise reduction effect. That is, the cooling medium can achieve both cooling and noise reduction effects. Furthermore, the sound after passing through the cooling medium and the cooling plate 31 can also be eliminated by the sound-absorbing cotton 5. The cooling plate 31 is cooled by the heat sink 33, the cooling medium and the fan 21 working together, so that the setting of the sound-absorbing cotton 5 will not reduce the cooling effect, thereby improving the cooling and noise reduction effects at the same time.

[0065] Reference Figure 2 , Figure 5 and Figure 6 The cooling assembly 4 includes a liquid storage tank 41, a pump body 42, an inlet pipe 43, and an outlet pipe 44. A support plate is fixedly installed on the outer wall of the cabinet 1. The liquid storage tank 41 is placed on the upper surface of the support plate and contains cooling medium. The pump body 42 is fixedly installed inside the liquid storage tank 41. The inlet pipe 43 is fixedly installed on the pump body 42, and the other end of the inlet pipe 43 is fixedly connected to the upper surface of the cooling plate 31 through the mounting hole 11. At the same time, the outlet pipe 44 is fixedly installed on the lower surface of the cooling plate 31, and the other end of the outlet pipe 44 passes through the mounting hole 11 and is fixedly connected to the upper surface of the liquid storage tank 41. Both the inlet pipe 43 and the outlet pipe 44 are connected to the cooling cavity 32.

[0066] When the pump body 42 is started, the cooling medium is added to the cooling chamber 32 through the inlet pipe 43. Then, the cooling medium in the cooling chamber 32 flows back to the storage tank 41 through the outlet pipe 44, thereby cooling the cooling plate 31. At the same time, the fan 21 is started, so that the heat on the cooling plate 31 can be dissipated into the air more quickly through multiple heat sinks 33, thereby improving the heat dissipation and cooling effect inside the cabinet 1.

[0067] Multiple air outlets are provided on the inner wall of the cabinet 1 where the air inlet 13 is opened and on the outside of the air inlet 13 and the fan 21, so that the air inside the cabinet 1 can be blown out through the air outlets. Sound-absorbing cotton 5 is also provided on the two inner walls of the cabinet 1 on the side of heat dissipation plate 14 and heat dissipation plate 2, thereby further improving the sound absorption effect. Tighten the positioning nut 63 away from the cooling plate 31, move the cooling plate 31 so that the heat dissipation fins 33 are separated from the cabinet 1, and then the heat dissipation plate 2 15 can be moved upward to remove the cooling plate 31 structure. The installation can be achieved by reversing the operation.

[0068] Reference Figure 5 and Figure 6 The liquid storage tank 41 is equipped with a vacuum mechanism 7, which includes a buoyancy plate 71, a telescopic component 72, a waterproof and breathable membrane 73, and a liquid inlet and air extraction assembly 8. The buoyancy plate 71 is vertically slidably installed in the liquid storage tank 41 and floats on the surface of the cooling medium. The telescopic component 72 is fixedly installed at the connection between the liquid outlet pipe 44 and the liquid storage tank 41 and is vertically downward and fixedly connected to the buoyancy plate 71. At the same time, the telescopic component 72 has a vertical telescopic effect and guides the cooling medium in the liquid outlet pipe 44 to the liquid storage tank 41 below the buoyancy plate 71. The buoyancy plate 71 is provided with a plurality of vertically penetrating vent holes 74. The waterproof and breathable membrane 73 is fixedly installed on the lower surface of the buoyancy plate 71 and blocks the cooling medium from passing through the vent holes 74 while allowing air to pass through the vent holes 74.

[0069] The liquid inlet and air extraction assembly 8 is used to add cooling medium to the liquid storage tank 41 located below the buoyancy plate 71 and extract air from the liquid storage tank 41 located above the buoyancy plate 71. The liquid inlet and air extraction assembly 8 includes a liquid inlet pipe 81 and an air extraction pipe 82. The liquid inlet pipe 81 is fixedly installed on the upper surface of the liquid storage tank 41 and extends vertically downward through the buoyancy plate 71 to below the buoyancy plate 71. A liquid inlet valve 83 for controlling opening and closing is fixedly installed on the liquid inlet pipe 81. The air extraction pipe 82 is fixedly installed on the upper surface of the liquid storage tank 41 and communicates with the liquid storage tank 41 located above the buoyancy plate 71. An air extraction valve 84 for controlling opening and closing is fixedly installed on the air extraction pipe 82. The air extraction pipe 82 is used to connect to a vacuum pump for extracting air from the liquid storage tank 41.

[0070] The buoyancy plate 71 moves downward under the action of gravity, and the telescopic component 72 is used to position the buoyancy plate 71. When adding cooling medium, the cooling medium is added to the storage tank 41 through the liquid inlet pipe 43. The addition of cooling medium causes the air in the storage tank 41 to move to the top of the buoyancy plate 71 through the waterproof and breathable membrane 73. The vacuum pump is started and the air in the storage tank 41 is extracted through the air extraction pipe 82. After the surface of the cooling medium comes into contact with the buoyancy plate 71, it pushes the buoyancy plate 71 upward until the cooling medium is added. The vacuum pump continues to start until the vacuuming is completed. This completes the addition of cooling medium and vacuuming. Vacuuming makes the cooling medium flow more easily and reduces the transmission of noise, further improving the cooling and noise reduction effect.

[0071] When the pump body 42 is started, the cooling medium flows back through the outlet pipe 44 and the telescopic component 72 to the storage tank 41 located below the buoyancy plate 71. When the level of the cooling medium changes, the buoyancy plate 71 can move vertically automatically, so that the internal space can accommodate the change in liquid volume. This allows the cooling medium through the outlet pipe 44 and the telescopic component 72 to fill the internal space of the outlet pipe 44 and the telescopic component 72, thereby reducing the risk of noise caused by incomplete filling and further improving the cooling and noise reduction effect.

[0072] The working principle of this application embodiment is as follows:

[0073] When fan 21 is activated, outside air is blown onto cooling plate 31 for cooling, causing hot air inside cabinet 1 to move to cooling plate 31 for cooling. At the same time, pump 42 is activated, allowing cooling medium to enter cooling chamber 32 to cool cooling plate 31. Heat on cooling plate 31 is dissipated through heat sink 33. Noise inside cabinet 1 is moved to sound-absorbing cotton 5 for elimination by airflow. Air inside cabinet 1 is moved out through air outlet, and some remaining noise is moved to sound-absorbing cotton 17 for further elimination. This achieves noise elimination and cooling of cabinet 1, improving both cooling and noise reduction effects.

[0074] When the pump body 42 is started, the cooling medium flows back through the outlet pipe 44 and the telescopic component 72 to the storage tank 41 located below the buoyancy plate 71. When the level of the cooling medium changes, the buoyancy plate 71 can move vertically automatically, so that the internal space can accommodate the change in liquid volume. This allows the cooling medium through the outlet pipe 44 and the telescopic component 72 to fill the internal space of the outlet pipe 44 and the telescopic component 72, thereby reducing the risk of noise caused by incomplete filling and further improving the cooling and noise reduction effect.

[0075] This application discloses a magnetically controlled reactor.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
