Description

Technical Field

[0001] This invention relates to the field of transformer heat dissipation technology, and more specifically, to a high-efficiency heat dissipation device and method for special industrial transformers. Background Technology

[0002] In power systems, transformers, as core equipment for energy conversion and transmission, bear the crucial responsibility of converting high-voltage electrical energy into low-voltage electrical energy. Their stable and efficient operation directly affects the safety and reliability of the entire power system. However, during transformer operation, the heat generated by current passing through resistance, along with hysteresis and eddy current losses in the iron core, causes the temperature inside and around the transformer to continuously rise. If heat dissipation is not effective, the internal temperature of the transformer will exceed its design limits, not only reducing its efficiency and service life but also potentially causing serious faults such as insulation aging and winding short circuits, posing a significant threat to the stable operation of the power system.

[0003] Currently, the commonly used heat dissipation methods mainly include natural cooling and air cooling. Air cooling mainly improves heat dissipation efficiency by installing cooling fans to increase airflow speed. However, long-term operation of cooling fans will draw fine dust from the air into the heat dissipation device, reducing its heat dissipation efficiency. At the same time, transformers generate static electricity during operation, which will also attract dust from the air, causing the dust to adhere to the transformer surface and affecting its normal operation. In view of this, we propose a high-efficiency heat dissipation device for special industrial transformers. Summary of the Invention

[0004] One of the objectives of this invention is to provide a high-efficiency heat dissipation device for special industrial transformers, in order to solve the problems mentioned in the background art above:

[0005] Existing transformer cooling devices draw dust into the device during operation, reducing its efficiency.

[0006] To achieve the above objectives, the present invention provides a high-efficiency heat dissipation device for special industrial transformers, comprising a heat dissipation chamber, wherein a heat dissipation component and a flow guiding component are disposed inside the heat dissipation chamber, and the flow guiding component includes two first flow guiding plates, the sides of which are respectively fixedly connected to two separate inner walls of the heat dissipation chamber. A second flow guiding plate is disposed on the upper side of the first flow guiding plate and is fixedly disposed inside the heat dissipation chamber. Both the first and second flow guiding plates are inclined upwards. A ventilation opening is provided on the upper side of the heat dissipation chamber, and a dust extraction fan is fixedly disposed inside the ventilation opening. A turbulence evacuation component is disposed between the first and second flow guiding plates.

[0007] When the air inside the heat dissipation chamber is agitated, it flows upward along the two No. 1 guide plates, and then flows along the two No. 2 guide plates to the lower side of the vacuum fan, which sucks out the air and dust from inside the heat dissipation chamber.

[0008] As a further improvement to this technical solution, the heat dissipation assembly includes a first heat dissipation fan, which is slidably disposed inside the heat dissipation chamber. The inner wall of the heat dissipation chamber is symmetrically and fixedly provided with slide rails for limiting the first heat dissipation fan. The side wall of the heat dissipation chamber is provided with heat dissipation holes corresponding to the position of the first heat dissipation fan.

[0009] When the No. 1 cooling fan starts, it agitates the air inside the cooling chamber and draws in outside air through the cooling holes, exchanging it with the air inside the cooling chamber. When sliding, the No. 1 cooling fan slides back and forth along two slide rails.

[0010] As a further improvement to this technical solution, a lead screw is rotatably installed inside the heat dissipation chamber. The lead screw rotates through the middle of the cooling fan. A motor is fixedly installed on one side of the heat dissipation chamber, and the motor shaft is fixedly connected to one end of the lead screw.

[0011] When the motor starts, it drives the No. 1 lead screw to rotate reciprocally, and at the same time, the No. 1 lead screw drives the No. 1 cooling fan to move.

[0012] As a further improvement to this technical solution, a first synchronous belt is provided at one end of the first lead screw. The first synchronous belt is rotatably disposed inside the heat dissipation chamber. One end of the first synchronous belt is meshed with one end of the first lead screw. A toothed groove matching the first synchronous belt is provided at one end of the first lead screw.

[0013] While the motor drives the No. 1 lead screw to rotate, the No. 1 synchronous belt also rotates along with the No. 1 lead screw.

[0014] As a further improvement to this technical solution, a second cooling fan is provided at the end of the first synchronous belt away from the first cooling fan. The second cooling fan is slidably disposed inside the heat dissipation chamber, and slide rails for limiting the second cooling fan are symmetrically fixed on the inner wall of the heat dissipation chamber.

[0015] The second cooling fan and the first cooling fan simultaneously agitate the air inside the heat dissipation chamber. The second cooling fan moves back and forth along the slide rail inside the heat dissipation chamber as it slides.

[0016] As a further improvement to this technical solution, a second lead screw is inserted through the middle of the second cooling fan. The second lead screw is rotatably located inside the heat dissipation chamber, and a fixing block is provided at the end of the second lead screw near the first synchronous belt.

[0017] When the No. 2 lead screw rotates, it drives the No. 2 cooling fan to move back and forth. The fixing block is used to limit one end of the No. 2 lead screw.

[0018] As a further improvement to this technical solution, the fixed block is internally equipped with a first gear and a second gear, which mesh with each other. The shaft of the first gear is meshed with one end of the first synchronous belt, and the second gear is fixedly mounted on one end of the second lead screw.

[0019] When the first synchronous belt rotates, it drives the first gear to rotate. At the same time, the first gear drives the second gear to rotate in the opposite direction, and the second gear drives the second lead screw to rotate.

[0020] As a further improvement to this technical solution, the turbulence assembly includes two turbulence plates, which are respectively disposed on the upper side of two No. 1 guide plates. The turbulence plates are rotatably disposed inside the heat dissipation chamber. One end of each of the two turbulence plates is meshed with a No. 1 lead screw and a No. 2 lead screw, respectively, and a No. 2 synchronous belt is connected to it. A transformer body is fixedly disposed inside the heat dissipation chamber, and the transformer body is disposed between the two No. 1 guide plates.

[0021] When lead screws No. 1 and No. 2 rotate, they drive two synchronous belts No. 2 to rotate. The synchronous belts No. 2 drive the spoilers to rotate and stir the air inside the heat dissipation chamber upward, thus accelerating the airflow inside the heat dissipation chamber.

[0022] The second objective of this invention is to provide a method for efficient heat dissipation of special industrial transformers, employing the aforementioned efficient heat dissipation device for special industrial transformers, comprising the following steps:

[0023] S1, start cooling fan No. 1 and cooling fan No. 2 to initially agitate the air inside the heat dissipation chamber and form a circulating airflow;

[0024] S2, start the motor. The motor drives the first lead screw to rotate. During the rotation, the first lead screw drives the first cooling fan to move back and forth along its axis, further agitating the air in different positions in the heat dissipation chamber and enhancing air convection.

[0025] S3, during the rotation of the first lead screw, the first timing belt is driven to rotate, the first timing belt drives the first gear to rotate, and then drives the second gear meshing with it to rotate in the opposite direction.

[0026] S4, the second gear drives the second lead screw to rotate in the opposite direction, thereby causing the second cooling fan to move back and forth in the opposite direction to the first cooling fan;

[0027] S5, during the rotation of lead screw No. 1 and lead screw No. 2, simultaneously drive two synchronous belts No. 2 to rotate. The two synchronous belts No. 2 further drive the two spoilers to rotate and disturb, enhancing the flow and mixing of air inside the heat dissipation chamber.

[0028] S6, after being disturbed, the air flows upward along the two No. 1 guide plates under the guidance of the turbulence, which drives the dust inside the heat dissipation chamber to rise with the airflow. Then the air and dust flow together along the two No. 2 guide plates to the lower area of ​​the dust extraction fan.

[0029] S7, turn on the vacuum fan to suck up the air and dust accumulated inside the heat dissipation chamber and expel the dust to the outside of the device.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] In this high-efficiency heat dissipation device for special industrial transformers, a second synchronous belt drives a baffle plate to agitate the air inside the heat dissipation chamber. The air inside the heat dissipation chamber flows upward along two first guide plates, while the dust inside the heat dissipation chamber also flows upward with the airflow. Subsequently, the air and dust inside the heat dissipation chamber flow along two second guide plates to the lower side of the dust extraction fan, which then sucks out the dust from inside the heat dissipation chamber. This device automatically cleans the dust inside the heat dissipation chamber while cooling the transformer body, preventing excessive dust from being drawn into the heat dissipation chamber and affecting the normal operation of the device, thus improving the heat dissipation efficiency of the device.

When the primary heat dissipation fan 21 moves, it moves left and right along the two slide rails. The side wall of the heat dissipation chamber 1 is provided with heat dissipation holes corresponding to the position of the primary heat dissipation fan 21. When the primary heat dissipation fan 21 is running, it draws air from outside the heat dissipation chamber 1 into the interior of the heat dissipation chamber 1 and agitates the air inside the heat dissipation chamber 1, thereby accelerating the exchange speed of air inside and outside the heat dissipation chamber 1.

[0045] Please see Figures 2-4As shown, a lead screw 22 is rotatably installed inside the heat dissipation chamber 1. The lead screw 22 rotates through the middle of the cooling fan 21.

The shaft of the motor 23 is fixedly connected to one end of the lead screw 22. The motor 23 is used to drive the lead screw 22 to rotate. When using the device, the user first starts the cooling fan 21 to agitate the air inside the heat dissipation chamber 1. At the same time, the user starts the motor 23 to drive the lead screw 22 to rotate. The lead screw 22 drives the cooling fan 21 to move back and forth. At the same time, the cooling fan 21 agitates the air in multiple places inside the heat dissipation chamber 1.

[0046] Please see Figures 3-5 As shown, a first synchronous belt 24 is provided at one end of the first lead screw 22. The first synchronous belt 24 is rotatably disposed inside the heat dissipation chamber 1. One end of the first synchronous belt 24 is meshed with one end of the first lead screw 22. One end of the first lead screw 22 has a toothed groove that matches the first synchronous belt 24. When the first lead screw 22 rotates, it drives the first synchronous belt 24 to rotate. A second heat dissipation fan 25 is provided at the end of the first synchronous belt 24 away from the first heat dissipation fan 21. The second heat dissipation fan 25 is slidably disposed inside the heat dissipation chamber 1. The positions of the second heat dissipation fan 25 and the first heat dissipation fan 21 are always symmetrical about the center position of the heat dissipation chamber 1. The inner wall of the heat dissipation chamber 1 is symmetrically fixed with slide rails for limiting the second heat dissipation fan 25. When the user starts the first heat dissipation fan 21, the second heat dissipation fan 25 is started at the same time. The first heat dissipation fan 21 and the second heat dissipation fan 25 simultaneously agitate the air inside the heat dissipation chamber 1.

[0047] Please see Figures 5-6 As shown, a second lead screw 26 is rotatably inserted in the middle of the second cooling fan 25. The second lead screw 26 is rotatably mounted inside the heat dissipation chamber 1. When the second lead screw 26 rotates, it drives the second cooling fan 25 to move back and forth. A fixing block 27 is set at the end of the second lead screw 26 near the first synchronous belt 24. A first gear 28 and a second gear 29 are rotatably mounted inside the fixing block 27. The first gear 28 and the second gear 29 mesh with each other. The shaft of the first gear 28 is connected to the first synchronous belt 24. One end of the gear is engaged with the other end. The second gear 29 is fixedly mounted on one end of the second lead screw 26. When the first synchronous belt 24 rotates, it drives the first gear 28 to rotate. At the same time, the first gear 28 drives the second gear 29 to rotate in the opposite direction. The second gear 29 drives the second lead screw 26 to rotate and drives the second cooling fan 25 to move back and forth. The direction of rotation of the second lead screw 26 is opposite to that of the first lead screw 22. At the same time, the direction of movement of the second cooling fan 25 is opposite to that of the first cooling fan 21.

The two first airflow guiding plates 31 are fixedly connected to two separate inner walls of the heat dissipation chamber 1 on opposite sides. The transformer body 4 is fixedly installed inside the heat dissipation chamber 1. The transformer body 4 is located between the two first airflow guiding plates 31. The two first airflow guiding plates 31 are respectively located below the first cooling fan 21 and the second cooling fan 25. When the first cooling fan 21 and the second cooling fan 25 are started, they continuously blow the air inside the heat dissipation chamber 1 toward the two sides of the transformer body 4 near the first cooling fan 21 and the second cooling fan 25, thereby rapidly cooling the transformer body 4.

[0049] Please see Figures 2-5 As shown, a second guide plate 32 is provided on the upper side of the first guide plate 31. The second guide plate 32 is fixedly installed inside the heat dissipation chamber 1. Both the first guide plate 31 and the second guide plate 32 are inclined upwards. The first guide plate 31 and the second guide plate 32 are used to guide the air inside the heat dissipation chamber 1 to flow upwards. When the first cooling fan 21 and the second cooling fan 25 are started, they agitate the air inside the heat dissipation chamber 1 and at the same time suck some fine dust from the outside of the heat dissipation chamber 1 into the heat dissipation chamber 1. After the dust is sucked into the heat dissipation chamber 1, it flows continuously with the air inside the heat dissipation chamber 1. After being agitated by the first cooling fan 21 and the second cooling fan 25, the air inside the heat dissipation chamber 1 flows upwards along the two first guide plates 31.

[0050] Please see Figures 2-5 As shown, a turbulence assembly 34 is provided between the first guide plate 31 and the second guide plate 32. The turbulence assembly 34 includes two turbulence plates 341, which are respectively disposed on the upper side of the two first guide plates 31. The turbulence plates 341 are rotatably disposed inside the heat dissipation chamber 1. One end of the two turbulence plates 341 is meshed with the first lead screw 22 and the second lead screw 26 respectively, and a second synchronous belt 342 is connected to them. When the first lead screw 22 and the second lead screw 26 rotate, they drive the two second synchronous belts 342 to rotate. The second synchronous belt 342 drives the two baffles 341 to rotate. The baffles 341 stir the air inside the heat dissipation chamber 1 upward, accelerating the upward flow of the air inside the heat dissipation chamber 1. A vent is provided on the upper side of the heat dissipation chamber 1, and a dust suction fan 33 is fixedly installed inside the vent. When the air mixed with dust inside the heat dissipation chamber 1 flows upward, it flows along the two second baffles 32 to the lower side of the dust suction fan 33. Then, the user starts the dust suction fan 33 to suck out the air mixed with dust inside the heat dissipation chamber 1 through the vent.

[0051] In the specific use of the high-efficiency heat dissipation device for special industrial transformers in this embodiment, the user first starts the No. 1 cooling fan 21 and the No. 2 cooling fan 25 to agitate the air inside the heat dissipation chamber 1. Then the user starts the motor 23 to drive the No. 1 lead screw 22 to rotate. When the No. 1 lead screw 22 rotates, it drives the No. 1 cooling fan 21 to move back and forth and agitate the air in multiple places inside the heat dissipation chamber 1.

[0052] When lead screw 22 rotates, it drives synchronous belt 24 to rotate. Synchronous belt 24 drives gear 28 to rotate and gear 29 to rotate in the opposite direction. Gear 29 drives lead screw 26 to rotate in the opposite direction. At the same time, lead screw 26 drives cooling fan 25 to move back and forth. The direction of movement of cooling fan 25 is opposite to that of cooling fan 21.

[0053] When lead screw 22 and lead screw 26 rotate, they drive two synchronous belts 342 to rotate. At the same time, the two synchronous belts 342 drive two baffles 341 to agitate the air inside the heat dissipation chamber 1. The air inside the heat dissipation chamber 1 flows upward along the two baffles 31, and the dust inside the heat dissipation chamber 1 also flows upward with the airflow. Then, the air and dust inside the heat dissipation chamber 1 flow along the two baffles 32 to the lower side of the vacuum fan 33. Then, the user starts the vacuum fan 33 to suck out the dust inside the heat dissipation chamber 1, preventing too much dust from being sucked into the heat dissipation chamber 1 from affecting the normal operation of the device and improving the heat dissipation efficiency of the device.

[0060] S5, during the rotation of lead screw 22 and lead screw 26, the two synchronous belts 342 are driven to rotate simultaneously. The two synchronous belts 342 further drive the two baffles 341 to rotate and disturb, thereby enhancing the flow and mixing of air inside the heat dissipation chamber 1.

[0061] S6, the disturbed air flows upward along the two No. 1 guide plates 31 under the guidance of the turbulence, which drives the dust inside the heat dissipation chamber 1 to rise with the airflow.
