Description

Technical Field

[0001] The present invention mainly relates to the technical field of transformers, and specifically to an efficient heat dissipation and energy-saving transformer. Background Art

[0002] In the context of the electrical era, transformers, as key components, are widely integrated into household appliances and electronic devices with high technical requirements. During the energized operation of transformers, heat energy is generated in their iron cores and coils. If the heat energy cannot be dissipated quickly, it will have a significant negative impact on the performance of the transformers. In addition, the overheating problem of transformers may also pose a potential threat to the safe operation of the entire system.

[0003] Although traditional air-cooled transformer heat dissipation devices can improve the heat dissipation efficiency, in most designs, the arrangement form of the fins is single, and the optimization of the air flow path is insufficient, resulting in limited air-cooling effect and inability to fully play the role of heat exchange. In addition, during the operation of some heat dissipation devices, effective wind direction adjustment cannot be carried out according to the actual wind direction of the external environment, which affects the air flow efficiency and further reduces the heat dissipation effect. Summary of the Invention

A fixed box is installed at the bottom of the transformer main body. The finned tubes are used to enhance the heat exchange efficiency. The finned tubes are composed of a double-layer alloy tube and spiral fins, and the spiral fins are installed on the outer wall of the double-layer alloy tube; The auxiliary mechanism consists of two groups of air duct components, two groups of air inlet components, two groups of drive components, and an electronic wind vane. The electronic wind vane is installed at the top of the transformer main body through screws.

A number of communicating air outlet pipes are provided on the outer walls of the two straight pipes and the two U-shaped pipes close to the outer wall of the transformer body.

[0008] Specifically, on the outer wall of the long side of each transformer body at the position of the straight pipe, a first mounting plate is provided. On both sides of the outer wall of each first mounting plate, first fixing plates are provided. On both sides of the outer wall of each straight pipe close to the transformer body, first support plates are welded. The other end of each first support plate is welded and connected to the first fixing plate.

[0009] Specifically, on the outer wall of the short side of each transformer body at the position of the U-shaped pipe, a second mounting plate is provided.

[0010] Specifically, each first fixing plate and the first mounting plate are both inserted by screws and thread-fixed to the outer wall of the transformer body. Each second fixing plate and the second mounting plate are both inserted by screws and thread-fixed to the outer wall of the transformer body. At both ends of each U-shaped pipe, insertion pipes are integrally connected. Each insertion pipe is inserted and connected to the end of the straight pipe. A sealing ring is provided on the end face of each U-shaped pipe.

[0011] Specifically, each group of the air inlet assemblies includes a vertical pipe provided at the bent part of the U-shaped pipe. The vertical pipe is communicated with the inside of the U-shaped pipe. A rotatable L-shaped pipe is installed at the end of the vertical pipe away from the U-shaped pipe. A driven gear is fixedly sleeved on the L-shaped pipe. An air inlet hood is connected to the end of the L-shaped pipe away from the vertical pipe.

[0012] Specifically, each group of the drive assemblies includes an L-shaped plate. On one side of the lower surface of the L-shaped plate, a vertical plate is welded.

The electronic wind vane in the auxiliary mechanism detects the wind direction and, through data feedback, precisely adjusts the wind direction to ensure the optimal path of air circulation. After detecting the wind direction, the driving component drives the air inlet component to rotate at an angle through the dual-axis motor, realizing flexible adjustment of the wind direction and the air inlet angle. The natural wind enters the interior of the U-shaped tube through the air inlet cover, the L-shaped tube, and the vertical tube, forming a directional air current, and is discharged through the air outlet pipe and blown onto the surfaces of the finned tubes in other directions. Then, through wind direction control, the heat quickly enters a reasonable exhaust path, accelerating heat transfer and ensuring the stable operation of the transformer in a high-temperature environment and extending its service life.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as a limitation to the present invention.

[0019] The embodiments of the present invention will be described below according to its overall structure.

[0020] In this embodiment, please refer to Figures 1 - 3 As shown, a highly efficient heat dissipation and energy-saving transformer includes a transformer main body 1, a plurality of finned tubes 2 uniformly installed on the outer wall, and an auxiliary mechanism 3 for wind diversion. A fixed box 101 is installed at the bottom of the transformer main body 1. The finned tubes 2 are used to enhance the heat exchange efficiency. The finned tubes 2 are composed of a double-layer alloy tube 201 and a spiral fin 202. The spiral fin 202 is installed on the outer wall of the double-layer alloy tube 201. Both ends of the finned tube 2 are welded and fixed to the outer wall of the transformer main body 1. The double-layer alloy tube 201 is made of a copper-aluminum-graphene composite material, and a superconducting liquid is provided in the double-layer alloy tube 201. When the temperature is greater than 30 °C, the superconducting liquid is quickly activated and starts to circulate. The auxiliary mechanism 3 is composed of two groups of air duct components 4, two groups of air inlet components 5, two groups of driving components 6, and an electronic wind vane 7. The electronic wind vane 7 is installed at the top of the transformer body 1 by screws. Both groups of the air duct components 4 are located outside the finned tubes 2, and the two groups of the air duct components 4 are arranged in an up-and-down stacked manner. Both groups of the air inlet components 5 are arranged on the air duct components 4. Both groups of the driving components 6 are installed on the air duct components 4. The driving component 6 is used to adjust the air inlet direction of the air inlet component 5 according to the indication of the electronic wind vane 7. A controller is installed in the fixed box 101 by screws. The electronic wind vane 7 is connected to the controller through a data cable. The double-shaft motor 603 arranged in the driving component 6 is connected to the controller through a wire. Among them, the electronic wind vane 7 uses the potentiometer principle. When the wind vane rotates, it drives the sliding contact of the potentiometer and changes the output electrical signal.

[0021] When installing the finned tubes 2 and the auxiliary mechanism 3 on the transformer body 1, first weld and fix both ends of several finned tubes 2 to the outer wall of the transformer body 1 to ensure that the welding joints are sealed and leak-free. Subsequently, fix the two groups of air duct components 4 to the outer wall of the transformer body 1 by screws respectively, so that the straight tubes 401 and the U-shaped tubes 405 of the air duct components 4 are both located outside the finned tubes 2. Then install the driving component 6 on the air duct component 4 by screws to ensure its stability and meshing connection with the driven gear 5021 of the air inlet component 5. Finally, install the electronic wind vane 7 on the top of the transformer body 1 and connect it to the controller through a data cable, thus completing the installation. And during transportation, the auxiliary mechanism can be disassembled to improve the transportation efficiency. During the operation of the transformer, through the double-layer alloy tube 201, high-efficiency heat transfer is achieved by using its excellent thermal conductivity and superconducting liquid. And when the temperature is greater than 30 °C, the superconducting liquid is quickly activated to circulate and take away a large amount of heat. At the same time, when natural wind appears, the electronic wind vane 7 monitors the wind direction change in real time and transmits the data to the controller. After receiving the data, the controller analyzes it through an algorithm and accurately controls the operation of the actuator (the double-shaft motor 603 in the text) of the driving component 6, and then controls the rotation of the air inlet component 5 to change the air inlet direction, so that the actuator (the air inlet hood 503) of the air inlet component 5 faces the direction of the natural wind. The natural wind enters the air duct component 4 through the air inlet hood 503 and is guided by the air duct component 4 to the surface of the finned tubes 2 of the transformer body 1, enabling the air to more effectively surround and contact the spiral fins 202 of the finned tubes 2 and accelerating heat dissipation. Thus, through the double-layer alloy tube 201 and the spiral fins 202, the heat exchange efficiency is enhanced, the heat generated during the working process is effectively dissipated, and the heat dissipation efficiency is improved. And by cooperating with the electronic wind vane, using data transmission and feedback, the wind direction is accurately adjusted to form an internal and external collaborative heat dissipation mechanism, significantly improving the operation stability of the transformer, ensuring the stable operation of the transformer in a high-temperature environment, and extending the service life.

[0022] Please refer to Figures 4 - 6 As shown, each set of the air duct assemblies 4 includes two straight pipes 401 and two U-shaped pipes 405. The two straight pipes 401 are respectively located on the long side of the transformer body 1, and the two U-shaped pipes 405 are respectively located on the short side of the transformer body 1.

A sealing ring is provided on the end face of each U-shaped pipe 405; Each set of the air inlet assemblies 5 includes a vertical pipe 501 provided at the bent portion of the U-shaped pipe 405. The vertical pipe 501 is communicated with the inside of the U-shaped pipe 405. An L-shaped pipe 502 is rotatably installed at the end of the vertical pipe 501 away from the U-shaped pipe 405. A driven gear 5021 is fixedly sleeved on the L-shaped pipe 502. An air inlet hood 503 is connected to the end of the L-shaped pipe 502 away from the vertical pipe 501.

[0023] During installation, first press the first mounting plate 404 against the outer wall of the transformer body 1, so that the first mounting plate 404 passes through the gap between a plurality of finned tubes 2 and the transformer body 1. Then place the first fixing plates 403 on both sides of the outer wall of the first mounting plate 404, and tightly connect the first fixing plates 403 and the first mounting plate 404 with screws and thread-fix them to the outer wall of the transformer body 1. At this time, the two first support plates 402 and the branch pipe 401 wrap a plurality of finned tubes 2 on this surface. Then install the other side of the transformer body 1 according to the same method; Then, press the second mounting plate 408 tightly against the outer wall of the transformer body 1, pass it through the gaps between the finned tubes 2, place the second fixing plate 407 on both sides of it, and tightly connect and thread-fix it to the outer wall with screws. At this time, the insertion tube 4051 at the end of the U-shaped tube 405 is tightly butted against the straight tube 401, and the sealing ring ensures no leakage, thus completing the overall installation of the air duct assembly 4; Natural wind enters the L-shaped tube 502 through the air inlet hood 503, enters the U-shaped tube 405 through the vertical tube 501, and flows along the U-shaped tube 405 and the straight tube 401 to form a directional air flow, which is discharged from the air outlet pipe 409 and blows onto the surfaces of the finned tubes 2 in other directions of the transformer body 1, accelerating heat transfer, ensuring the stable operation of the transformer in a high-temperature environment, and extending its service life.

[0024] Please refer to Figure 3 、 Figure 7 and Figure 8 As shown, each set of the driving assemblies 6 includes an L-shaped plate 601. One side of the lower surface of the L-shaped plate 601 is welded with a vertical plate 602. A double-shaft motor 603 is installed on the vertical plate 602 with screws. One output end of the double-shaft motor 603 penetrates through the L-shaped plate 601. Both output ends of the double-shaft motor 603 are connected with a rotating shaft 604 through flanges. Fixed sleeves of active gears 605 are respectively arranged on the outer walls of the ends of the two rotating shafts 604. Each active gear 605 is meshed and connected with a driven gear 5021 arranged in the air inlet assembly 5. The two ends of the L-shaped plate 601 are respectively fixed on a first support plate 402 and a second support plate 406 arranged in the air duct assembly 4 with screws. Slots are opened on both the first support plate 402 and the second support plate 406, and matching insertion plates are welded on the lower surface of the L-shaped plate 601 at the positions of the slots.

[0025] During installation, place the two ends of the L-shaped plate 601 on the first support plate 402 and the second support plate 406 respectively, so that the insertion plates are tightly fitted with the opened slots, and then fix the L-shaped plate 601 on the first support plate 402 and the second support plate 406 with screws. At this time, the active gears 605 arranged at both ends of the double-shaft motor 603 will be accurately meshed with the driven gears 5021 in the air inlet assembly 5 to complete the installation; After the electronic wind vane 7 monitors the change of the wind direction, the controller controls the double-shaft motor 603 to work. The two output ends of the double-shaft motor 603 drive the connected rotating shafts 604 to rotate. The rotating shafts 604 drive the active gears 605 to rotate, so that the active gears 605 drive the driven gears 5021 to rotate, thereby adjusting the angle of the air inlet assembly 5, ensuring that the natural wind always enters along the best path, and further being able to adjust the air inlet direction of the air duct assembly 4 according to the wind direction to maximize the air volume and the heat exchange efficiency.

[0026] The working principle of the present invention is as follows: When installing the finned tubes 2 and the auxiliary mechanism 3 onto the transformer body 1, first, both ends of several finned tubes 2 are welded and fixed to the outer wall of the transformer body 1 to ensure that the welded joints are sealed without leakage. Subsequently, the first mounting plate 404 is closely attached to the outer wall of the transformer body 1, such that the first mounting plate 404 passes through the gaps between several finned tubes 2 and the transformer body 1. Then, the first fixing plate 403 is placed on both sides of the outer wall of the first mounting plate 404, and the first fixing plate 403 is tightly connected to the first mounting plate 404 with screws and is thread-fixed to the outer wall of the transformer body 1. At this time, the two first support plates 402 and the branch pipe 401 enclose several finned tubes 2 on this side. Then, the other side of the transformer body 1 is installed according to the same method. Next, the second mounting plate 408 is closely attached to the outer wall of the transformer body 1, making it pass through the gaps of the finned tubes 2, and the second fixing plate 407 is placed on both sides of it. It is tightly connected with screws and thread-fixed to the outer wall. At this time, the insertion pipe 4051 at the end of the U-shaped pipe 405 is closely docked with the straight pipe 401, and the sealing ring ensures no leakage, thus completing the overall installation of the air duct assembly 4; Both ends of the L-shaped plate 601 are respectively placed on the first support plate 402 and the second support plate 406, such that the insertion plate fits tightly into the opened slots. Then, the L-shaped plate 601 is fixed to the first support plate 402 and the second support plate 406 with screws. At this time, the driving gears 605 provided at both ends of the dual-axis motor 603 will accurately mesh with the driven gear 5021 in the air intake assembly 5. Finally, the electronic wind vane 7 is installed on the top of the transformer body 1 to complete the installation of the auxiliary mechanism 3; During the operation of the transformer, through the double-layer alloy tube 201, efficient heat transfer is achieved by using its excellent thermal conductivity and superconducting liquid. And the superconducting liquid is quickly activated to circulate when the temperature is greater than 30°C, taking away a large amount of heat. At the same time, when natural wind appears, the electronic wind vane 7 monitors the wind direction changes in real time and transmits the data to the controller. After receiving the data, the controller analyzes it through an algorithm and accurately regulates the operation of the dual-axis motor 603. The two output ends of the dual-axis motor 603 drive the connected rotating shafts 604 to rotate. The rotating shafts 604 drive the driving gears 605 to rotate, such that the driving gears 605 drive the driven gears 5021 to rotate. The driven gears 5021 drive the L-shaped tube 502 and the air intake cover 503 to rotate on the vertical tube 501, making the air intake cover 503 face the direction of the natural wind. The natural wind enters the L-shaped tube 502 through the air intake cover 503, passes through the vertical tube 501 and enters the U-shaped tube 405, and flows along the U-shaped tube 405 and the straight pipe 401 to form a directional air current, which is discharged from the air outlet pipe 409 and blows onto the surfaces of the finned tubes 2 in other directions of the transformer body 1 for efficient heat dissipation.
