In addition, the present invention can replace each module according to the manufacturing, testing and maintenance requirements. This modularization improves the flexibility and maintainability of the system. During installation or upgrading, the module combination can be adjusted according to the on-site requirements, which makes it easier to achieve customized services, and large integrated transformers may be limited by size and weight during transportation and installation. The split design can solve this problem by assembling on site. Each module is smaller in size and lighter in weight, which is convenient for transportation and handling, and reduces the requirements for installation site space. In addition, the split design only requires replacing or upgrading the corresponding module without replacing the entire transformer, which greatly reduces the maintenance time and cost, improves the availability and economy of the system, and can optimize the materials and structures of each module according to different environmental conditions, such as selecting a more suitable protection level and material in a high temperature, humid or corrosive environment, thereby improving the environmental adaptability of the entire transformer system.
[0018] The present invention provides an integrated transformer with a controllable heat dissipation component, which adopts a circulating heat dissipation control to form an air pressure rotation for stirring and heat dissipation. This compressed air system can provide continuous and powerful airflow, directly acting on the heat-generating components of the transformer, such as coils and iron cores, to effectively take away heat. This active heat dissipation method is more efficient than natural convection or static air cooling, and can quickly reduce the operating temperature of the transformer, improve thermal management capabilities, and is beneficial to the long-term stable operation of the transformer. It can also achieve effective squeezing and rotation of high-temperature gas to accelerate air flow or drive coolant circulation, which can improve the overall efficiency of the heat dissipation system, especially by increasing the heat exchange surface area and fluid dynamics effects to enhance the heat exchange process, and such a mechanism can form a certain degree of self-sustaining cycle, that is, it partially relies on the heat energy generated by itself to drive the heat dissipation process, reducing the demand for external energy, and the efficient heat energy conversion and heat dissipation mechanism can theoretically reduce the volume and complexity of the heat dissipation system, which may have advantages for application environments with limited space.
[0019] The present invention provides an integrated transformer with a controllable heat dissipation component, which uses air cooling to further dissipate heat. This effect increases the heat exchange rate around and inside the transformer, thereby effectively reducing the temperature of the coil and the insulating material. This is particularly important for applications with high loads or high ambient temperatures. It can ensure that the transformer operates within a safe temperature range to avoid performance degradation or damage caused by overheating. Good heat dissipation conditions reduce the impact of thermal stress on internal components of the transformer, such as reducing the aging rate of insulating materials, thereby significantly extending the overall service life of the transformer and reducing the frequency of maintenance and replacement. The air cooling system has a relatively simple structure and low installation and maintenance costs. It does not require additional circulating pumps, radiators and other components, reducing initial investment and subsequent operation and maintenance costs. The air cooling design makes the transformer easy to deploy and adjust in various installation environments, without being restricted by geographical location, and without considering the liquid circulation path or the problems caused by handling the liquid cooling medium. Compared with the liquid cooling system, the air cooling system is easier to maintain, mainly by regularly checking and cleaning the fan and filter to ensure unobstructed air circulation.

[0036] As attached Figure 1 To Attachment Fig. 9 As shown:
[0037] An integrated transformer with a controllable heat dissipation component includes a transformer frame 11 and a transformer module arranged inside the transformer frame 11. The transformer frame 11 is also provided with a heat dissipation module, and the heat dissipation module includes a heat dissipation fin 12 arranged on the surface of the transformer frame 11. A secondary liquid cooling component 47, a primary liquid cooling component 27 and a circulating heat dissipation control 26 are arranged inside the transformer frame 11. The primary liquid cooling component 27 has a first liquid cooling cavity 51 for accommodating the transformer module. The primary liquid cooling component 27 and the circulating heat dissipation control 26 are connected through a pipeline. The secondary liquid cooling component 47 has a second liquid cooling cavity. The circulating heat dissipation control 26 includes a blade component 52 and a high-pressure cylinder 53. The blade component 52 is located in the inner cavity of the secondary liquid cooling component 47. The input end of the high-pressure cylinder 53 is connected to the primary liquid cooling component through a pipeline. The high-pressure gas in the component 27, the output end of the high-pressure cylinder 53 is connected to the pneumatic drive mechanism 54 through a pipeline, the output shaft of the pneumatic drive mechanism 54 is connected to the central column 37 of the blade assembly 52, the blade assembly 52 includes an angle-adjustable heat dissipation blade 36 hinged to the outer wall of the central column 37, the central column 37 has a central cavity 55, the output end of the high-pressure cylinder 53 is also connected to the central cavity 55 through a pipeline, an adjustment block 56 is slidably arranged in the central cavity 55, an angle adjustment gear 57 is arranged at the hinge between the heat dissipation blade 36 and the central column 37, a transmission mechanism for the secondary liquid cooling component 47 is arranged between the adjustment block 56 and the angle adjustment gear 57, the transmission mechanism converts the longitudinal movement of the adjustment block 56 into the rotation of the angle adjustment gear 57, and the angle adjustment gear 57 adjusts the expansion angle of the heat dissipation blade 36 relative to the central column 37.
[0038] In this embodiment, the transmission mechanism of the secondary liquid cooling assembly 47 converts the longitudinal movement of the adjustment block 56 into the rotation of the angle adjustment gear 57. The high-pressure cylinder 53 also includes a pneumatic drive mechanism 54, which is connected to the compression chamber 30, and the output shaft of the pneumatic drive mechanism 54 is connected to the center column 37.
[0039] The air pressure is transmitted to the inside of the compression chamber 30. The air pressure inside the compression chamber 30 has two effects. First, the high-pressure gas is transmitted to the central cavity 55 inside the central column 37 through the pipeline. Under the action of the air pressure, the adjustment block 56 moves downward, and the adjustment block 56 drives the angle adjustment gear 57 to rotate through the transmission mechanism. The angle adjustment gear 57 drives the heat dissipation blades 36 to swing relative to the central column 37. When the air pressure inside the compression chamber 30 is too low, the heat dissipation blades 36 are retracted on the surface of the central column 37. At this time, the rotation diameter of the heat dissipation blades 36 is small. When the air pressure inside the compression chamber 30 increases, the heat dissipation blades 36 are expanded by the action of the adjustment block 56. At this time, the rotation diameter of the heat dissipation blades 36 increases.
[0040] When the temperature and air pressure inside the first-stage liquid cooling component 27 are low, it is difficult for the pneumatic drive mechanism 54 to overcome the resistance of the blades and convert the internal energy of the high-temperature air pressure into the mechanical energy of the central column 37. In order to solve this problem, we have designed an angle-adjustable heat dissipation blade 36. When the air pressure inside the compression chamber 30 is too low, the rotation diameter of the heat dissipation blade 36 is smaller. At this time, the resistance to the rotation of the blade is reduced, and the pneumatic drive mechanism 54 is easier to start.
[0041] When the temperature inside the first-stage liquid-cooling component 27 is high, in order to improve the utilization of the internal energy of the high-temperature gas, the heat dissipation blades 36 are expanded by the adjustment block 56. At this time, the rotation diameter of the heat dissipation blades 36 increases, and the rotation resistance of the heat dissipation blades 36 increases. The pneumatic drive mechanism 54 converts more internal energy of the high-temperature gas into mechanical energy of the heat dissipation blades 36. In this state, the heat dissipation blades 36 are fully expanded and the stirring effect has a wider range. The coolant in the second-stage liquid-cooling component 47 is stirred, which increases the convection of the coolant and improves the heat dissipation effect.
[0042] Preferably, a compression chamber 30 is provided inside the high-pressure cylinder 53, and an inner groove 40 is installed on the inner wall of the compression chamber 30. A sliding plate 48 is slidably provided between the inner grooves 40, and a return spring 41 is installed between the sliding plate 48 and the inner wall of the compression chamber 30. An outer sleeve 33 is fixedly connected to the surface of the sliding plate 48, and a sliding rod 46 is fixedly connected to the surface of the outer sleeve 33. A support frame 31 is wrapped on the surface of the outer sleeve 33, and a rotating inner column 34 is rotatably installed inside the support frame 31. The surface of the rotating inner column 34 is provided with an arc-shaped groove 45, and the sliding rod 46 slides in the arc-shaped groove 45.

[0044] Preferably, a plurality of heat conductive sheets 22 are provided in a vertical array on the surface of the inner bellows 21, and the other end of the heat conductive sheet 22 is inserted into the interior of the secondary liquid cooling assembly 47. A plurality of square holes are provided in a horizontal array on the surface of the heat conductive sheet 22, and the heat conductive sheet 22 adopts a flexible plate body, and the heat conductive sheet 22 and the heat dissipation blades 36 are arranged horizontally. When the heat dissipation blades 36 are rotating, the heat conductive sheet 22 can be swung to different amplitudes according to the fluidity of the water body, and the square holes provided on the surface of the heat conductive sheet 22 will push the water body up and down, thereby accelerating the heat dissipation of the water body.
[0045] Preferably, a transformer 28 is installed inside the primary liquid cooling component 27 , and a bidirectional water pump 29 is connected between the primary liquid cooling component 27 and the heat sink 23 .
[0046] Preferably, a guide tube 42 is connected to the outer end of the high-pressure cylinder 53 , and the guide tube 42 is connected to the inside of the first-stage liquid cooling component 27 . A one-way valve 43 is provided inside the guide tube 42 .
[0047] Preferably, a plurality of heat dissipation fins 12 are arranged in an array on the surface of the transformer frame 11 . The heat dissipation fins 12 include symmetrically arranged heat-conducting rods 15 , and a plurality of heat dissipation fins 16 are arranged in an array between the heat-conducting rods 15 .
[0048] Preferably, an exhaust fan 50 is installed on the surface of the heat dissipation box 23 , and an exhaust port 49 is fixedly connected to the output end of the exhaust fan 50 . The exhaust port 49 passes through the transformer frame 11 and is installed between the heat dissipation fins 12 .
[0049] Preferably, a plurality of conductive sheets 13 are arranged in an array on the upper surface of the transformer frame 11 , and the conductive sheets 13 include a primary conductive sheet 17 and a secondary conductive sheet 18 .
[0050] Specific use of the present invention:
[0051] When the present invention is used, it is first fixed in an outdoor substation. Then, the secondary conductive sheet 18 and the primary conductive sheet 17 are connected by a power supply wire to ensure smooth installation and then turn on the power supply to put the device in a standby state. Before the transformer 28 is operated, it is necessary to check whether the cooling oil in the transformer module 27 has covered the top of the transformer to ensure normal startup and subsequent transformer operations.
[0052] The heat generated during the operation of the transformer 28 triggers the cooling system in the module. Once the temperature is too high, the coolant will quickly exchange heat, and this process will generate hot gas high pressure. The high-pressure hot gas is introduced into the compression chamber 30 through the guide tube 42, and then acts on the sliding plate 48, causing it to be compressed. This pressure causes the outer sleeve 33 to move downward and push the compression spring 44, while driving the rotating inner column 34 to perform a rotation along the arc-shaped slide 45. The rotation of the rotating inner column 34 drives the central column 37 of the component to rotate, and the movement of the central column 37 synchronously drives the heat dissipation blades 36 to achieve continuous air compression.
[0053] As the high-pressure gas enters the compression chamber 30, the continuous compression of the air and the long-term rotation of the center column 37 are promoted. When the high-pressure gas is introduced into the compression chamber 30, it not only supports the continuous compression of the air, but also ensures the long-term stable rotation of the center column 37. This air pressure is then transmitted to the inside of the compression chamber 30, playing a dual role: first, the high-pressure gas is transmitted along the pipeline and acts on the central cavity 55 built into the center column 37, prompting the adjustment block 56 to move downward. The movement of the adjustment block 56 is achieved through a set of transmission devices, which in turn drives the angle adjustment gear 57 to rotate. As the angle adjustment gear 57 rotates, the heat dissipation blades 36 show a change in swinging posture around the center column 37. When the air pressure inside the compression chamber 30 drops to a lower level, the heat dissipation blades 36 automatically gather to the surface of the center column 37, reducing their rotation diameter and optimizing the working efficiency under low air pressure. On the contrary, if the air pressure inside the compression chamber 30 rises, the adjustment block 56 drives the heat dissipation blades 36 to expand outward, expanding the rotation diameter of the blades to cope with the increased air pressure and improve the heat dissipation efficiency. This design realizes an intelligent mechanism for dynamically adjusting the heat dissipation efficiency according to the internal air pressure. During this process, 37 continuously stirs the coolant in the second liquid cooling chamber 25 to promote heat exchange.
[0054] The heat exchange in the second liquid cooling chamber 25 is completed by the cooperation of the outer bellows 20 and the inner bellows 21 embedded in the transformer frame 11, wherein the heat conducting sheet 22 of the inner bellows 21 absorbs and transfers the heat of the liquid in the liquid cooling chamber to its surface. When it is detected that the surface temperature of the inner bellows is too high, the embedded heat dissipation fan 19 is immediately started to inhale the outside air to reduce the surface temperature. Its rotation can also promote the discharge of heat from the outer bellows 20, and the heat is conducted to the outside through the upper and lower openings. In addition, the exhaust fan 50 arranged outside the heat dissipation box 23 is responsible for extracting the hot air in the equipment cavity, which is quickly dissipated and cooled through the heat dissipation fins 12, thereby maintaining the temperature inside the equipment stable.
[0055] The present invention provides an integrated transformer with a controllable heat dissipation component. The split-type heat dissipation box and the transformer module can adopt a targeted heat dissipation strategy for the key heat-generating components (such as coils and cores) of the transformer, and can more accurately manage and control the temperature of each part. By optimizing the heat dissipation path and increasing the heat dissipation area, the overall heat dissipation efficiency is improved, which helps to reduce the working temperature and prolong the service life. In addition, the present invention can replace each module according to the manufacturing, testing and maintenance requirements. This modularization improves the flexibility and maintainability of the system. During installation or upgrading, the module combination can be adjusted according to the on-site requirements, which makes it easier to achieve customized services, and large integrated transformers may be limited by size and weight during transportation and installation. The split design can solve this problem by assembling on site. Each module is smaller in size and lighter in weight, which is convenient for transportation and handling, and reduces the requirements for installation site space. In addition, the split design only requires replacing or upgrading the corresponding module without replacing the entire transformer, which greatly reduces the maintenance time and cost, improves the availability and economy of the system, and can optimize the materials and structures of each module according to different environmental conditions, such as selecting a more suitable protection level and material in a high temperature, humid or corrosive environment, thereby improving the environmental adaptability of the entire transformer system.
[0056] The present invention provides an integrated transformer with a controllable heat dissipation component, which uses a circulating heat dissipation control to form an air pressure rotation to stir and dissipate heat. This compressed air system can provide a continuous and powerful airflow, directly acting on the heat-generating components of the transformer, such as coils and cores, to effectively take away heat. This active heat dissipation method is more efficient than natural convection or static air cooling, can quickly reduce the operating temperature of the transformer, improve thermal management capabilities, and is conducive to the long-term stable operation of the transformer. It can also achieve effective squeezing and rotation of high-temperature gas to accelerate air flow or drive coolant circulation, which can improve the overall efficiency of the heat dissipation system, especially by increasing the heat exchange surface area and fluid dynamics effects to enhance the heat exchange process, and such a mechanism can form a certain degree of self-sustaining cycle, that is, partially relying on the heat energy generated by itself to drive the heat dissipation process, reducing the demand for external energy, and the efficient heat energy conversion and heat dissipation mechanism can theoretically reduce the volume and complexity of the heat dissipation system, which may have advantages for space-constrained application environments.
[0057] The present invention is an integrated transformer with a controllable heat dissipation component that uses air cooling for further heat dissipation. This effect increases the heat exchange rate around and inside the transformer, thereby effectively reducing the temperature of the coil and the insulating material. This is particularly important for applications with high loads or high ambient temperatures, and can ensure that the transformer operates within a safe temperature range to avoid performance degradation or damage caused by overheating, and good heat dissipation conditions reduce the impact of thermal stress on the internal components of the transformer, such as reducing the aging rate of the insulating material, thereby significantly extending the overall service life of the transformer, reducing the frequency of maintenance and replacement, and the air cooling system structure is relatively simple, and the installation and maintenance costs are low. It does not require additional components such as circulating pumps and radiators, reducing initial investment and subsequent operation and maintenance costs, and the air cooling design makes the transformer easy to deploy and adjust in various installation environments, not limited by geographical location, and does not need to consider the problems caused by the liquid circulation path or the treatment of liquid cooling media, and compared with the liquid cooling system, the maintenance of the air cooling system is simpler. Mainly, regularly check and clean the fan and filter to ensure that the air circulation is unobstructed.

The high-pressure gas is provided in the form of a pipe, wherein the output end of the high-pressure cylinder (53) is connected to a pneumatic drive mechanism (54) via a pipeline, the output shaft of the pneumatic drive mechanism (54) is connected to a central column (37) of the blade assembly (52), the blade assembly (52) comprises an angle-adjustable heat dissipation blade (36) hinged to an outer wall of the central column (37), the central column (37) has a central cavity (55), the output end of the high-pressure cylinder (53) is connected to the central cavity (55) via a pipe, an adjustment block (56) is slidably arranged in the central cavity (55), an angle adjustment gear (57) is arranged at a hinge between the heat dissipation blade (36) and the central column (37), and the adjustment block (56) and the angle adjustment gear (57) are arranged at a hinge between the heat dissipation blade (36) and the central column (37). A transmission mechanism is arranged between the adjusting gears (57), and the transmission mechanism converts the longitudinal movement of the adjusting block (56) into the rotation of the angle adjusting gear (57) so as to adjust the expansion angle of the heat dissipation blade (36) relative to the central column (37); a compression chamber is arranged inside the high-pressure cylinder, an inner slide groove is installed on the inner wall of the compression chamber, a sliding plate is slidingly arranged between the inner slide grooves, a return spring is installed between the sliding plate and the inner wall of the compression chamber, an outer sleeve is fixedly connected to the surface of the sliding plate, a sliding rod is fixedly connected to the surface of the outer sleeve, a support frame is wrapped around the surface of the outer sleeve, a rotating inner column is rotatably installed inside the support frame, an arcuate slide groove is provided on the surface of the rotating inner column, and the sliding plate is fixedly connected to the surface of the outer sleeve. The rod slides in the arc-shaped slide groove; the heat generated during the operation of the transformer (28) triggers the cooling system in the module; once the temperature is too high, the coolant quickly performs heat exchange, and high-pressure hot air is generated during this process; the high-pressure hot air is introduced into the compression chamber (30) through the guide tube (42), and then acts on the sliding plate (48), causing it to be compressed; this pressure causes the outer sleeve (33) to move downward and push the compression spring (44), while driving the rotating inner column (34) to perform a rotational movement along the arc-shaped slide groove (45); the rotation of the rotating inner column (34) drives the central column (37) of the component to rotate, and the movement of the central column (37) synchronously drives the heat dissipation blades (36) to achieve continuous air compression;As the high-pressure gas enters the compression chamber (30), the continuous compression of the air and the long-term rotation of the center column (37) are promoted. When the high-pressure gas is introduced into the compression chamber (30), it not only supports the continuous compression of the air, but also ensures the long-term stable rotation of the center column (37); this air pressure is then transmitted to the inside of the compression chamber (30), playing a dual role: first, the high-pressure gas is transmitted along the pipeline and acts on the central cavity (55) built into the center column (37), prompting the adjustment block (56) to move downward; the movement of the adjustment block (56) is achieved through a set of transmission devices, thereby driving the angle adjustment gear (57) to rotate; As the angle adjustment gear (57) rotates, the heat dissipation blades (36) change their swinging posture around the central column (37); when the air pressure inside the compression chamber (30) drops to a lower level, the heat dissipation blades (36) automatically gather toward the surface of the central column (37), reducing their rotation diameter and optimizing the working efficiency under low air pressure; on the contrary, if the air pressure inside the compression chamber (30) rises, the adjustment block (56) drives the heat dissipation blades (36) to expand outward, expanding the rotation diameter of the blades to cope with the increased air pressure and improve the heat dissipation efficiency; an intelligent mechanism for dynamically adjusting the heat dissipation efficiency according to the internal air pressure is realized; during this process, the central column (37) continuously stirs the coolant in the second liquid cooling chamber (25) to promote heat exchange.
