Description

TECHNICAL FIELD

[0002] In the field of modern industrial equipment, the integrated design of transformers, frequency converters and motors becomes more and more common, aiming to achieve more compact structure and higher operating efficiency. However, such integrated design puts higher requirements on the compact layout and collaborative heat dissipation of components. On the one hand, the internal space of the equipment is increasingly limited, requiring electrical components to be placed in a more reasonable and compact manner; on the other hand, the traditional single air-cooled or water-cooled heat dissipation method has been unable to meet the large amount of heat generated by heat generators such as transformers. Therefore, more efficient and innovative heat dissipation solutions are needed. The mixed heat dissipation technology of water cooling and air cooling stands out in the heat dissipation field of many high-power electrical equipment due to its excellent heat conduction performance.

[0017] Advantages and effects of the present application:

[0018] 1. The present application uses a closed water-cooled shell structure, which is specially used for cooling the transformer in the integrated device. The design realizes the circulation of air in the closed shell through the air cooling mechanism below the transformer. The air cooling mechanism blows air upward, and the airflow can flow along the surface of the transformer winding through the guidance of the insulating cylinder and the air resistance plate. After the hot air is discharged from above the insulating cylinder, it is first cooled by the circulating water cooling plate above, and the water collecting platform also plays a role in guiding the airflow, ensuring that the hot air flows through the passage in the middle of the water collecting platform. The hot air cooled by the circulating water cooling plate is forced to flow to both sides due to the blocking effect of the circulating water cooling plate. The presence of the airflow guide plate further guides the hot air to flow along the inner wall of the water-cooled shell for secondary cooling, thereby effectively transferring heat. Finally, the cooled air returns to the bottom of the transformer

[0019] 2. The present application uses innovative two-stage cooling technology. First, through the guidance of the air resistance plate and the airflow guide plate, the airflow is guided to the circulating water cooling plate above the transformer, thereby realizing the preliminary cooling of the hot air. Then, the blocking effect of the circulating water cooling plate causes the hot air to diffuse to both sides, and at this time the airflow guide plate plays a role again, guiding the airflow to flow along the side wall of the second shell. The circulating water cooling pipe is arranged in the side wall of the second shell to further cool the hot air. This unique design can quickly remove a large amount of heat generated by the transformer during high-load operation, effectively reduce the working temperature of the equipment, and significantly improve its heat dissipation performance.

[0020] 3. In the present application, the inclination angle of the circulating water cooling plate can be flexibly adjusted by the height adjuster at the top of the water cooling shell. Adjusting the inclination angle of the circulating water cooling plate can bring significant advantages. First, the circulating water cooling plate not only cools the hot air initially, but also guides the air flow. Due to the obstruction of the circulating water cooling plate, after initial cooling, the hot air flows to both sides through the gap between the circulating water cooling plate and the air flow guide plate due to the inclination. By adjusting the inclination angle, the gap increases, the hot air flow increases, and thus flows more effectively to both sides for secondary cooling. Second, during shutdown inspection, condensate water may form on the surface of the circulating water cooling plate. Adjusting the inclination angle can make the condensate water flow faster into the water collection platform below the circulating water cooling plate, thereby avoiding the accumulation of condensate water on the circulating water cooling plate and preventing possible adverse effects.

[0021] 4. The second shell of the transformer in the present application adopts a modular design, wherein the side wall of the second shell is composed of an inner wall and an outer wall, and mounting grooves are provided on the sides of the inner wall and the outer wall. The circulating water cooling pipe is arranged inside the side wall of the second shell through the mounting grooves. This design facilitates the disassembly and cleaning of the circulating water cooling pipe in the second shell, reduces the complexity and time cost of maintenance, and enables users to perform daily maintenance and troubleshooting more quickly and efficiently.

[0022] 5. The present application innovatively optimizes the internal air path structure. First, a wind resistance plate is added to the outside of the insulating cylinder of the transformer, effectively restraining and blocking the air flow blown by the bottom fan of the transformer. The synergistic effect of the wind resistance plate and the insulating cylinder ensures smooth airflow along the surface of the transformer winding. Second, the air flow guide plate not only guides the flow of hot air, but also reduces the gap between the side wall of the first shell while maintaining a constant air flow, thereby increasing the air speed and significantly improving the cooling efficiency.

[0023] 6. Compared with the traditional air cooling technology, the present application relies only on the internal air circulation driven by the built-in fan of the equipment, and combines a series of water cooling technology to achieve cooling. This process is completely carried out in a closed space, effectively isolated from the external environment, thereby significantly reducing noise during operation, suitable for application environments with strict noise control requirements.

[0024] 7. The closed design of the shell of the present application can prevent external dust, moisture and other impurities from entering the interior of the equipment, reducing electrical faults and safety hazards caused by impurities. The transformer operates in a relatively closed and stable environment, greatly improving the safety and reliability of the equipment. BRIEF DESCRIPTION OF DRAWINGS

[0058] The second installation cavity of the embodiment of the present application is a space surrounded by a top wall, a side wall and a bottom wall, wherein the top wall, the side wall and the bottom wall are sealingly connected, and specifically, the side wall is further provided with an outlet 18 of the transformer 25, the motor 1 and the frequency converter 4; wherein the inside of the side wall is provided with a circulating water cooling pipeline 33, and the circulating water cooling pipeline 33 is S-shaped. The second shell 9 of the transformer 25 in the present application adopts a modular design, wherein the side wall of the second shell 9 is composed of an inner wall and an outer wall, and the inner wall and the outer wall are provided with mounting grooves on the side surfaces, and the circulating water cooling pipeline 33 is arranged in the inside of the side wall of the second shell 9 through the mounting grooves. This design facilitates the disassembly and cleaning of the circulating water cooling pipeline 33 in the second shell 9, reduces the complexity and time cost of maintenance, and enables users to perform daily maintenance and troubleshooting more quickly and efficiently. At the same time, the shell of the present application adopts a closed design to prevent external dust, moisture and other impurities from entering the inside of the equipment, thereby reducing electrical faults and safety hazards caused by impurities. The transformer 25 operates in a relatively closed and stable environment, greatly improving the safety and reliability of the equipment.

[0059] The air cooling mechanism of the embodiment of the present application comprises an air resistance plate 20, a fan 22 and an airflow guide plate 17, wherein the fan 22 is arranged at the lower part of the second installation cavity through a transformer mounting platform 21, wherein a gap is left between the transformer mounting platform 21 and the bottom wall, and the transformer mounting platform 21 is provided with a plurality of ventilation openings 23, each of which is in communication with the inside of the insulating cylinder 19.

[0060] The airflow guide plate 17 is provided with two airflow guide plates 17, both of which are arranged on the transformer mounting platform 21, and the two airflow guide plates 17 are arranged on the two sides of the transformer 25, respectively. A predetermined space is left between the two airflow guide plates 17 and the side wall of the second shell 9, and a predetermined distance is left between the top of the two airflow guide plates 17 and the top wall of the second shell 9. The air resistance plate 20 is provided with a mounting hole corresponding to the insulating cylinder 19, and the air resistance plate 20 is sealingly connected with the side wall of the second shell 9 and the airflow guide plate 17 around it.

[0061] The air flow guide plate 17 of the application plays a guiding role on the flow of internal air, reduces the gap between the side wall 9, increases the air flow speed, and improves the heat dissipation efficiency; in addition, the internal air path structure is innovatively optimized. First, the wind resistance plate 20 is additionally arranged outside the insulating cylinder 19 of the transformer 25, which effectively restrains and blocks the air flow blown by the bottom fan of the transformer 25. The cooperation of the wind resistance plate 20 and the insulating cylinder 19 ensures the smooth flow of the air flow 34 along the surface of the transformer winding. Secondly, the air flow guide plate 17 reduces the gap between the side wall of the first casing 9 while guiding the flow of hot air, thereby increasing the wind speed of the air flow 34 under the premise of keeping the air flow constant, significantly improving the cooling efficiency, and compared with the traditional air cooling technology, the application only relies on the built-in fan 22 of the equipment to drive the internal air circulation, and combines a series of water cooling technology to realize cooling. This process is completely carried out in a closed space, which is effectively isolated from the external environment, thereby significantly reducing the noise during operation, and is suitable for application environments with strict noise control requirements.

[0062] When the transformer 25 of the embodiment of the application is cooled, the path of the cooling air is as follows: the air flow 34 flows upwards from the air outlet of the fan 22, passes through the gap between the high-voltage winding, the low-voltage winding and the core inside the insulating cylinder 19 of the transformer, then flows through the cavity between the air flow guide plate 17 and the top circulating water cooling plate 14 to the space between the air flow guide plate 17 on both sides and the side wall of the second casing 9, and then flows downwards through the cavity between the transformer mounting platform 21 and the bottom wall of the second casing 9, and returns to the air inlet of the fan 22 from the cavity between the transformer mounting platform 21 and the bottom wall of the second casing 9 to complete the circulation. The application uses an innovative two-stage cooling technology. First, under the guidance of the wind resistance plate 20 and the air flow guide plate 17, the air flow 34 is guided to the circulating water cooling plate 14 above the transformer 25, thereby realizing the preliminary cooling of the hot air. Then, the blocking effect of the circulating water cooling plate 14 causes the hot air to diffuse to both sides, and at this time, the air flow guide plate 17 plays a guiding role again, guiding the air flow 34 to flow along the side wall of the second casing 9. The circulating water cooling pipeline 33 is arranged in the side wall of the second casing 9, which further cools the hot air. This unique design can quickly remove a large amount of heat generated by the transformer 25 during high-load operation, effectively reduce the working temperature of the equipment, and significantly improve the heat dissipation performance.

[0063] The embodiment of the present application further comprises a top water-cooled plate assembly, wherein the top water-cooled plate assembly comprises a water-cooled plate height adjuster and circulating water-cooled plates 14, wherein the circulating water-cooled plates 14 are provided in two, each of the circulating water-cooled plates 14 has an S-shaped water-cooled flow cavity, and the S-shaped water-cooled flow cavity has a liquid inlet 11 and a liquid outlet 15, one side of each of the two circulating water-cooled plates 14 adjacent to each other is connected with the water-cooled plate height adjuster, and the other side of each of the two circulating water-cooled plates 14 away from each other is fixedly connected with the top of an air flow guide plate 17 through a hinge 32, and the two circulating water-cooled plates 14 are arranged at a predetermined angle.

[0064] The water-cooled plate height adjuster of the embodiment of the present application comprises height adjustment frames 7 and connecting rod assemblies, wherein the height adjustment frames 7 are provided in two, and each of the height adjustment frames 7 is arranged on the outer wall of the top of the casing, and the height adjustment frames 7 have a plurality of height adjustment grooves in the height direction;

[0065] The connecting rod assemblies are provided in two, each of the connecting rod assemblies comprises a connecting rod 8 and a connecting frame 29, wherein the connecting rod 8 is matched with the size of the height adjustment groove, and the connecting rod 8 is placed in the height adjustment groove; one end of the connecting frame 29 is fixedly connected with the connecting rod 8 above, and the other end of the connecting frame 29 extends downwardly through the top wall 10 and is fixedly connected with the circulating water-cooled plate 14 away from the hinge 32; each of the circulating water-cooled plates 14 is arranged on the top of the air flow guide plate 17 through the hinge 32 and the connecting frame 29.

[0066] The embodiment of the present application further comprises a water collecting platform 16, wherein the water collecting platform 16 is arranged below the two adjacent circulating water-cooled plates 14, the water collecting platform 16 is arranged on the top of the air flow guide plate 17 through a connecting piece, and a cooling air passage is left in the middle of the water collecting platform 16. The present application uses a closed water-cooled shell structure, which is specially used for cooling the transformer 25 in the integrated device. The design realizes the circulation of air in the closed shell through the air cooling mechanism below the transformer 25. The air cooling mechanism blows air upward, and the air flow 34 flows along the surface of the transformer winding through the guidance of the insulating cylinder 19 and the air resistance plate 20. After the hot air is discharged from above the insulating cylinder 19, it is firstly cooled by the circulating water-cooled plate 14 above, and the water collecting platform 16 also plays a role in guiding the air flow, ensuring that the hot air flows through the passage in the middle of the water collecting platform 16. The hot air cooled by the circulating water-cooled plate 14 is forced to flow to both sides due to the blocking effect of the circulating water-cooled plate 14. The presence of the air flow guide plate 17 further guides the hot air to flow along the inner wall of the water-cooled shell for secondary cooling, thereby effectively transferring heat. Finally, the cooled air returns to the bottom of the transformer.

[0067] The water collecting platform 16 of the embodiment of the present application is provided with a drainage communication pipe 27, one end of which communicates with the water collecting platform 16, and the other end of which extends downward and reaches outside the side wall of the second casing 9; and the airflow guide plate 17 is of a rectangular structure with a receiving cavity in the middle. In the present application, the inclination angle of the circulating water cooling plate 14 can be flexibly adjusted by the height adjuster on the top of the water cooling shell. Adjusting the inclination angle of the circulating water cooling plate 14 can bring significant advantages. First, the circulating water cooling plate 14 not only cools the hot air initially, but also guides the airflow. After the initial cooling, the hot air will flow to both sides through the gap between the circulating water cooling plate 14 and the airflow guide plate 17 due to the inclination. By adjusting the inclination angle, the gap increases, the hot air flow increases, and thus the hot air flows to both sides more effectively for secondary cooling. Second, during the shutdown inspection, condensate water may be generated on the surface of the circulating water cooling plate 14. Adjusting the inclination angle can make the condensate water flow into the water collecting platform 16 below the circulating water cooling plate 14 more quickly, thereby avoiding the accumulation of condensate water on the circulating water cooling plate 14 and preventing possible adverse effects.

[0068] Specifically, the transformer 25 of the embodiment of the present application is placed on the transformer mounting platform 21, and a gap is left between the transformer mounting platform 21 and the bottom wall to facilitate air circulation. During the installation and manufacture of the transformer 25, the insulating cylinder 19 and the air resistance plate 20 have been assembled together, and are positioned and fixed by the insulating cylinder fixing buckle 26 therebetween.

In addition, the water collecting platform 16 is firmly connected to the airflow guide plate 17 by the two side bolts 6, and the water collecting platform 16 has a large passage in the middle, which also plays a restraining role on the airflow, so that the airflow mainly flows through the middle passage.

[0069] One side of the circulating water cooling plate 14 is connected with the top of the air flow guide plate 17 through the rotatable hinge 32, and the other side of the circulating water cooling plate 14 is arranged on the corresponding height adjusting frame 7 through the connecting frame 29. In addition, the height adjusting frame 7 comprises an adjusting frame body and a support plate 30, the middle part of the adjusting frame body is provided with an opening, a plurality of height adjusting openings are correspondingly arranged on both sides of the opening along the height, the support plate 30 is inserted and matched with the height adjusting opening, the support plate 30 and the side wall of the opening of the adjusting frame body form a height adjusting groove, the connecting rod 8 is placed in the height adjusting groove, and the limiting baffle 31 is arranged at both ends of the connecting rod 8 to limit the movement thereof, the bottom of the connecting rod 8 is connected with the connecting frame 29, the top of the adjusting frame body is slidingly connected with the steel wire 28, and one end of the steel wire 28 penetrates through the top of the adjusting frame body and is connected with the connecting rod 8. Through the cooperation of the steel wire 28, the height of the connecting rod 8 can be adjusted up and down, so that the inclination angle of the circulating water cooling plate 14 is adjusted. Once the inclination angle of the circulating water cooling plate 14 is adjusted to the ideal state, the support plate 30 is reinserted into the new height adjusting opening, and the adjustment is completed.
