Description
Technical Field
[0001] This invention belongs to the technical field of converter cabinets, and particularly relates to a converter cabinet with a heat dissipation structure. Background Technology
[0002] A converter cabinet is an electrical equipment cabinet used for power form conversion and control. Its core function is to convert one form of electrical energy, such as direct current or alternating current of different frequencies, into another form of electrical energy that meets the requirements. At the same time, it realizes functions such as power regulation and fault protection. It is widely used in new energy power generation, industrial transmission, rail transportation and other fields, and is a key device to ensure stable power transmission and normal equipment operation.
[0003] Traditional converter cabinets employ a closed design, lacking an effective ventilation structure. The cabinet only contains two sets of reactor cooling fans, with power outputs consistent with the 2.5MW model, and have not been upgraded to meet actual cooling requirements. During hot, windy summer periods, obstructed airflow within the cabinet leads to persistently high temperatures. The outdoor water-cooled fans, constantly exposed to direct sunlight, experience a significant decrease in heat exchange efficiency, ultimately resulting in insufficient heat dissipation margin for the converter. This problem directly causes frequent high-temperature alarms from the IGBT modules within the cabinet. Furthermore, it accelerates the damage or aging of components such as the cabinet's components and reactor cooling fans due to prolonged high temperatures, affecting the stable operation of the equipment. Therefore, we propose a converter cabinet with a cooling structure. Summary of the Invention

[0021] The beneficial effects of this invention are: 1. This converter cabinet with a heat dissipation structure utilizes centrifugal fans, air intake devices, filters, liquid cooling devices, cooling fans, and heat-conducting copper pipes. The filter, along with a temperature sensor, detects the temperature inside the cabinet. When the temperature inside the cabinet becomes too high, the temperature controller activates two centrifugal fans, two air intake devices, the liquid cooling device, the cooling fan, and the heat-conducting copper pipes to dissipate heat from the cabinet. The filter prevents external dust from entering the cabinet. This design automatically activates the heat dissipation mechanism to quickly cool the cabinet when the internal temperature is too high, preventing the core components from being exposed to high temperatures for extended periods. This extends the lifespan of the core components, improves equipment stability, and reduces the replacement and maintenance costs of the core components.
[0022] 2. This converter cabinet with a heat dissipation structure, through the arrangement of a transmission rod, a brush, a first gear, a second gear, a third gear, a first incomplete gear, a second incomplete gear, a first synchronous pulley, a second synchronous pulley, a third gear slot, a fourth gear, a fifth gear, and a first servo motor, allows the transmission rod to reciprocate on one side of the fixed block, causing the transmission rod to drive the brush to reciprocate. The design of the above structure can prevent a large amount of external dust from accumulating on the filter, affecting the heat dissipation effect of the centrifugal fan and the air intake device, thereby ensuring the overall heat dissipation effect of the device.
[0023] 3. This converter cabinet with a heat dissipation structure allows users to move the tensioning wheel up and down via a tensioning wheel, slider, threaded rod, and a second servo motor. This tensioning wheel can compress the synchronous belt. The design of the above structure allows users to control the tension of the synchronous belt and prevent it from loosening during long-term use. Attached Figure Description

[0031] Example 1: Please see Figure 1 - Figure 11 As shown, this embodiment provides a converter cabinet with a heat dissipation structure, including a cabinet body 1, and further including: Two liquid cooling units 30 are fixedly connected to the top surface of the cabinet 1. Each of the two liquid cooling units 30 is equipped with two cooling fans 31. Each of the two liquid cooling units 30 has a heat-conducting copper pipe 32 fixedly connected to its outlet. One end of the heat-conducting copper pipe 32 passes through the inner cavity of the cabinet 1 and extends back to the outside to be fixedly connected to the inlet of the liquid cooling unit 30. The two heat-conducting copper pipes 32 are attached to the two sides of the electronic components inside the cabinet 1. Two centrifugal fans 2 are fixedly connected to one side of the cabinet 1, and the inner cavities of the two centrifugal fans 2 are connected to the inner cavity of the cabinet 1. Two air inlet devices 3 are fixedly connected inside the cabinet 1, and the inner cavity of the two air inlet devices 3 is connected to the inner cavity of the cabinet 1. A filter 5 is provided on one side of each of the two air inlet devices 3, and the two filters 5 are fixedly connected to the other side of the cabinet 1. Temperature controller 4 is fixedly connected to one side of cabinet 1, and the temperature sensor of temperature controller 4 is located inside cabinet 1. Temperature controller 4 is electrically connected to centrifugal fan 2, air inlet device 3 and liquid cooling device 30. Fixed block 6 is fixedly connected to the top surface of air inlet device 3. A transmission rod 7 is rotatably connected to one side of fixed block 6. A brush 8 is fixedly connected to the bottom end of transmission rod 7 and the brush 8 is in contact with filter 5. The reciprocating assembly is located inside the fixed block 6 and is used to drive the transmission rod 7 to reciprocate.
[0032] In operation, when the temperature controller 4 detects a high temperature inside the cabinet 1 via the temperature sensor, it will activate two centrifugal fans 2, two air intake devices 3, and two liquid cooling devices 30. The two air intake devices 3 will draw outside air into the inner cavity of the cabinet 1. At the same time, the two centrifugal fans 2 will extract heat from the cabinet 1 and discharge it to the outside. The two liquid cooling devices 30 will drive the coolant in the two heat-conducting copper pipes 32 to circulate, allowing the two heat-conducting copper pipes 32 to exchange heat from the cabinet 1 to the outside. The heat will also be dissipated by multiple cooling fans 31. When air enters the cabinet 1, the dust in the air will be filtered by two filters 5 to ensure that the entire device can automatically dissipate heat from the cabinet 1. During use, the user drives the transmission rod 7 to rotate back and forth through the reciprocating component, which in turn drives the brush 8 to rotate back and forth. This allows the brush 8 to clean the dust accumulated on the filter 5, ensuring that a large amount of dust does not accumulate on the filter 5 and affect the overall heat dissipation effect of the device.
[0033] Example 2: This embodiment provides a converter cabinet with a heat dissipation structure. In addition to the technical solutions of the above embodiments, it also has the following technical features, and the reciprocating component includes: The first gear groove 9 is formed in the fixed block 6. The first gear 10 and the second gear 11 are rotatably connected in the first gear groove 9 and mesh with each other. One end of the first gear 10 passes through the inner wall of the first gear groove 9 and extends into the fixed block 6 to be fixedly connected to the transmission rod 7. The second gear groove 12 is opened in the fixed block 6 and communicates with the first gear groove 9. The third gear 13 is rotatably connected in the second gear groove 12, and one end of the third gear 13 extends into the first gear groove 9 and is fixedly connected to the second gear 11. The first incomplete gear 14 and the second incomplete gear 15 are provided on both sides of the third gear 13, and the first incomplete gear 14 meshes with the third gear 13. The movable groove 16 is opened in the fixed block 6 and communicates with the second gear groove 12. The first synchronous pulley 17 and the second synchronous pulley 18 are rotatably connected in the movable groove 16. One end of the first synchronous pulley 17 extends into the second gear groove 12 and is fixedly connected to the second incomplete gear 15. A synchronous belt 19 meshes between the first synchronous pulley 17 and the second synchronous pulley 18. The third gear groove 20 is formed in the fixed block 6 and is connected to the movable groove 16 and the second gear groove 12. The fourth gear 21 and the fifth gear 22 are rotatably connected in the third gear groove 20 and mesh with each other. One end of the fourth gear 21 extends into the movable groove 16 and is fixedly connected to the second synchronous pulley 18. One end of the fifth gear 22 extends into the second gear groove 12 and is fixedly connected to the first incomplete gear 14. The first servo motor 23 is fixedly connected to one side of the fixed block 6, and the output shaft of the first servo motor 23 passes through one side of the fixed block 6 and extends into the second gear groove 12 to be fixedly connected to the first incomplete gear 14.
[0034] In operation, the user activates the first servo motor 23, causing its output shaft to drive the first incomplete gear 14 to rotate within the second gear slot 12. This causes the first incomplete gear 14 to drive the fifth gear 22 to rotate within the third gear slot 20. The fifth gear 22 then drives the fourth gear 21 to rotate in the reverse direction within the third gear slot 20. When the fourth gear 21 rotates in the reverse direction, it drives the second synchronous pulley 18 to rotate in the reverse direction within the movable slot 16. The second synchronous pulley 18, via the synchronous belt 19, drives the first synchronous pulley 17 to rotate in the reverse direction. When the first synchronous pulley 17 rotates in the reverse direction, it drives the second incomplete gear 15 to rotate in the reverse direction within the second gear slot 12. When the first... When the incomplete gear 14 rotates, the first incomplete gear 14 will drive the third gear 13 to rotate forward in the second gear groove 12. When the first incomplete gear 14 rotates to the appropriate position, the first incomplete gear 14 will disengage from the third gear 13. At the same time, the second incomplete gear 15 will mesh with the third gear 13, causing the second incomplete gear 15 to drive the third gear 13 to rotate in the second gear groove 12 in the opposite direction. When the third gear 13 reciprocates in the second gear groove 12, the third gear 13 will drive the second gear 11 to reciprocate in the first gear groove 9, causing the second gear 11 to drive the transmission rod 7 to reciprocate through the first gear 10, ensuring that the user can drive the transmission rod 7 to reciprocate.

[0036] In use, the user drives the slider 27 to move up and down along the second slide groove 26 via the drive component, which in turn drives the tensioning wheel 25 to move up and down along the first slide groove 24. This allows the tensioning wheel 25 to compress the synchronous belt 19, ensuring that the user can control the tension of the synchronous belt 19.
[0037] Example 4: This embodiment provides a converter cabinet with a heat dissipation structure. In addition to the technical solutions of the above embodiments, it also has the following technical features, and the drive components include: The second slide groove 26 is formed on the inner wall of the first slide groove 24.

[0038] In use, the user starts the second servo motor 29, which drives the threaded rod 28 to rotate in the second slide groove 26.

[0047] Working principle: When in use, when the temperature controller 4 detects that the temperature inside the cabinet 1 is high through the temperature sensor, the temperature controller 4 will start two centrifugal fans 2, two air intake devices 3, and two liquid cooling devices 30. The two air intake devices 3 will draw outside air into the inner cavity of the cabinet 1. At the same time, the two centrifugal fans 2 will extract the heat from the cabinet 1 and discharge it to the outside. The two liquid cooling devices 30 will drive the coolant in the two heat-conducting copper pipes 32 to circulate, allowing the two heat-conducting copper pipes 32 to exchange heat from the cabinet 1 to the outside. The heat is also dissipated by multiple cooling fans 31. When air enters the cabinet 1, the dust in the air will be filtered by two filters 5 to ensure that the whole device can automatically dissipate heat from the cabinet 1. In use, the user starts the first servo motor 23, causing its output shaft to drive the first incomplete gear 14 to rotate in the second gear slot 12. This causes the first incomplete gear 14 to drive the fifth gear 22 to rotate in the third gear slot 20. The fifth gear 22 then drives the fourth gear 21 to rotate in the third gear slot 20 in the opposite direction. When the fourth gear 21 rotates in the opposite direction, it drives the second synchronous pulley 18 to rotate in the opposite direction in the movable slot 16. The second synchronous pulley 18, via the synchronous belt 19, drives the first synchronous pulley 17 to rotate in the opposite direction. When the first synchronous pulley 17 rotates in the opposite direction, it drives the second incomplete gear 15 to rotate in the second gear slot 12 in the opposite direction. When the first incomplete gear 14 rotates, it drives the third gear 15 to rotate in the opposite direction. Gear 13 rotates forward in the second gear slot 12. When the first incomplete gear 14 rotates to the appropriate position, the first incomplete gear 14 will disengage from the third gear 13. At the same time, the second incomplete gear 15 will mesh with the third gear 13, causing the second incomplete gear 15 to drive the third gear 13 to rotate in the second gear slot 12 in the opposite direction. When the third gear 13 reciprocates in the second gear slot 12, the third gear 13 will drive the second gear 11 to reciprocate in the first gear slot 9. The second gear 11 will drive the transmission rod 7 to reciprocate through the first gear 10, causing the transmission rod 7 to drive the brush 8 to reciprocate, allowing the brush 8 to clean the dust accumulated on the filter 5, ensuring that a large amount of dust does not accumulate on the filter 5, thus affecting the heat dissipation effect of the overall device. In use, the user starts the second servo motor 29, which drives the threaded rod 28 to rotate in the second slide groove 26. This causes the slider 27 to move downward along the second slide groove 26 under the action of the threaded rod 28. The slider 27 then drives the tension wheel 25 to move downward along the first slide groove 24, causing the tension wheel 25 to compress the synchronous belt 19, ensuring that the user can control the tension of the synchronous belt 19.
