Description

Technical Field

[0001] This invention belongs to the field of new energy transformer technology, specifically a new energy transformer with high heat dissipation. Background Technology

[0002] The heat dissipation system is a core component of transformers in new energy power plants, directly determining the equipment's operational stability, service life, and energy efficiency. The highly volatile output of wind and solar power in new energy power plants causes transformer loads to frequently switch between light and full loads, resulting in irregular fluctuations in heat generation. This places stringent demands on the adaptability and efficiency of the heat dissipation system.

[0003] A high-heat-dissipation dry-type transformer, disclosed in announcement number CN120878411A, includes a transformer body, a supporting base block for supporting and mounting the transformer body, an air guide assembly detachably mounted above the supporting base block for delivering air into the transformer body to accelerate airflow, and a diffusion assembly located within the transformer body to diffuse and change the area and direction of the air delivered by the air guide assembly. The air guide assembly can guide the air output by the blower into the interior of the transformer body, forming a forced convection circulation. The air entering the transformer body passes through the diffusion assembly to broaden the coverage area of ​​the airflow, further enhancing the heat dissipation capacity of the windings and core. Simultaneously, it adjusts the vertically entering airflow into a spiral upward state, utilizing centrifugal effect to prolong the residence time of the airflow inside the transformer body, while increasing the contact area with the windings and core, thus enhancing heat exchange efficiency.

[0004] However, during the use of the aforementioned patent, the following problems were found: when the temperature of a local area of ​​the winding resistor rises, there is a lack of effective isolation and independent heat dissipation structure, which makes it impossible to quickly cut off the connection between the high-temperature area and other areas, which easily causes the high-temperature airflow to diffuse and accumulate, thereby affecting the heat dissipation of other parts, damaging the core components of the transformer, and resulting in low heat dissipation efficiency. Therefore, a new energy transformer with high heat dissipation is proposed. Summary of the Invention

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-9 This application provides a high-heat-dissipation new energy transformer, including a base 12 on which a transformer assembly 1 is mounted. The transformer assembly 1 integrates multiple winding resistors arranged side by side, and each winding resistor has an outer shell 11 and an inner shell 13 on its outer side. It should be noted that the inner shell 13 is preferably made of thermally conductive copper alloy, while the outer shell 11 is preferably made of steel with high rigidity and strength. This can prevent foreign objects from impacting the transformer assembly 1 and causing damage to the transformer assembly 1, and allows the heat generated by the transformer assembly 1 during operation to pass through the inner shell 13. The heat is conducted into the cavity formed between the outer shell 11 and the inner shell 13. Each inner shell 13 is concentrically arranged inside one outer shell 11, and a heat dissipation chamber is provided between the outer shell 11 and the inner shell 13. Each heat dissipation chamber is divided into several hierarchical chambers from bottom to top. This facilitates targeted heat dissipation of corresponding chambers when local heat accumulates in the winding resistor. To facilitate the handling of localized heat, at least two sets of hierarchical chambers are provided. A ventilation and heat dissipation system 2 for heat dissipation of the transformer assembly 1 is installed on the base 12. The ventilation and heat dissipation system 2 includes… Multiple fans 21 are provided, all of which are fixedly installed on the base 12 by mounting brackets 29. Each fan 21 has an air supply duct 23 at its output end. Multiple branch ducts 233 that are connected to the hierarchical chambers are provided on the air supply duct 23. It should be noted that the fans 21 are existing technology products and are used by power supply. The sealing unit 25 is provided in multiple sets and is installed in each level chamber to seal two adjacent level chambers; Multiple heat dissipation pipes 27 are provided and are respectively installed on the side wall of each level chamber. Each heat dissipation pipe 27 is arranged on the opposite side of the branch pipe 233, which allows the airflow to circulate once inside each level chamber before being discharged from the heat dissipation pipe 27, ensuring comprehensive heat dissipation. Optionally, a filter screen can be installed at the part of the heat dissipation pipe 27 that connects to the outside to prevent foreign objects from clogging the heat dissipation pipe 27.

[0023] The synchronous opening and closing unit 26 is provided in multiple sets and is installed on each sealing unit 25 to synchronously control the opening and closing degree of the heat dissipation pipe 27 on the corresponding level chamber.

[0024] Specifically, under normal operating conditions, by powering the fan 21, the fan 21 delivers airflow to the air supply duct 23 and distributes it to the lowest branch duct 233, thus entering the interior of the hierarchical chambers. The airflow cooled by the lower hierarchical chambers flows into the upper hierarchical chambers until it reaches the top of the heat dissipation chamber and is discharged, thereby carrying away the heat generated by the winding resistor and achieving the purpose of heat dissipation. However, when the internal temperature of a certain hierarchical chamber is high, the sealing unit 25 is triggered to cut off this hierarchical chamber from the upper hierarchical chamber, preventing the airflow carrying hot air from dissipating into the upper hierarchical chamber. At this time, the power of the fan 21 is increased to... The airflow is distributed into multiple streams. The first stream enters from the branch pipe 233 at the bottom layer, the second stream enters from the branch pipe 233 corresponding to the high-temperature layer, and the third stream enters from the branch pipe 233 above the high-temperature layer. Simultaneously, the sealing unit 25 drives the synchronous opening and closing unit 26 to operate. The synchronous opening and closing unit 26 opens the heat dissipation pipe 27 on the high-temperature layer chamber to a through state, so that the first and second streams of airflow carry heat and are directly discharged from the heat dissipation pipe 27, avoiding the problem of high-temperature airflow accumulating and not being discharged in time, which would affect the temperature of the upper layer chamber. The third stream of airflow continues to move upward based on this layer to ensure normal heat dissipation of the upper layer.

[0025] Furthermore, each of the aforementioned blocking units 25 includes, The stop block 2510 is fixedly connected to the inner wall of the outer shell 11 by the fixing bracket 259, and the outer edge of the stop block 2510 is sealed to the outer shell 11, and a gap is provided between the inner edge of the stop block 2510 and the inner shell 13. The sealing block 258 is located below the stop block 2510 and is used to seal the gap between the stop block 2510 and the inner shell 13. The heat feedback actuator, located in each level chamber, is used to push the sealing block 258 to seal the stop block 2510.

[0026] Specifically, the heat feedback actuator senses the temperature inside the chamber of that level and uses the principle of thermal expansion and contraction to drive the sealing block 258 to seal the block 2510.

[0027] Furthermore, each of the heat feedback execution components includes, Multiple sealing cylinders 251 are provided and are fixedly connected to the outer wall of the inner shell 13 by fixing blocks 255. A piston 253 is movably arranged inside each sealing cylinder 251. A sealing medium is provided between the sealing cylinder 251 and the piston 253. It should be noted that the sealing medium can be gaseous or liquid and can expand when heated. In this scheme, n-pentane liquid with a low boiling point phase change liquid is preferred. A lifting rod 254 is fixedly connected to the top of the piston 253. A lifting frame 256 is fixedly connected to the lifting rod 254. The lifting frame 256 is fixedly connected to the sealing block 258 through the extension frame 257. By providing a sealing medium, when the internal temperature of the chamber is sensed to rise, the lifting frame 256 is lifted by the principle of thermal expansion and contraction. The lifting frame 256 drives the sealing block 258 through the extension frame 257 to seal the stop block 2510. The through pipe 252 is connected to the side wall of multiple sealing cylinders 251 to connect the multiple sealing cylinders 251 together, so that the air pressure inside each sealing cylinder 251 is uniformly balanced.

[0028] Furthermore, a square chamber 271 is provided through the middle of each of the heat dissipation pipes 27, and the synchronous opening and closing unit 26 includes, The upper sealing plate 263 and the lower sealing plate 264 are slidably disposed inside the square cavity 271, and a reverse transmission assembly for driving the lower sealing plate 264 to move in the opposite direction to the upper sealing plate 263 is provided between the upper sealing plate 263 and the lower sealing plate 264. The connecting frame 261 is fixedly connected to a corresponding lifting frame 256, and the end of the connecting frame 261 away from the lifting frame 256 is fixedly connected to the upper sealing plate 263 through the first connecting block 262.

[0029] Specifically, when the heat feedback execution component drives the lifting frame 256 to move upward to block the stop block 2510, it can drive the connecting frame 261 to move upward. The connecting frame 261 drives the upper sealing plate 263 to move upward through the first connecting block 262, and then drives the lower sealing plate 264 to move downward through the reverse transmission component, thereby opening the through state simultaneously, so that the air carrying heat can be discharged from the heat dissipation pipe 27.

[0030] Furthermore, the reverse transmission assembly includes, A rotating shaft 265 is fixedly installed on the inner wall of a square chamber 271. A gear 266 is rotatably connected to the rotating shaft 265, and a rack 267 is meshed on both sides of the gear 266. The end of one rack 267 is fixedly connected to the upper sealing plate 263 through a second connecting block 268, and the end of the other rack 267 is fixedly connected to the lower sealing plate 264 through a second connecting block 268.

[0031] Specifically, during the up-and-down movement of the upper sealing plate 263, the corresponding rack 267 moves upward through the second connecting block 268 connected to it, which in turn drives the gear 266 to rotate on the rotating shaft 265. The gear 266 then drives another rack 267 to move downward, which in turn drives the lower sealing plate 264 to move downward. Through the above steps, the limited upward space of the blocking block 258 can be sealed, while allowing the channel of the heat dissipation pipe 27 to be opened to a large extent, thus facilitating the rapid discharge of the airflow carrying heat.

[0032] Furthermore, each of the aforementioned air supply ducts 23 is provided with a cooling unit 22 in its middle section, the cooling unit 22 comprising: The connecting shell 221 is installed through and fixedly on the air supply duct 23, located below the branch duct 233; Cooler 222 is located inside the connecting shell 221 and is used for cooling. It should be noted that the cooler 222 is an existing product that is powered on and is convenient for cooling in extreme environments.

[0033] Furthermore, each of the air supply ducts 23 is provided with a flow divider 231 for evenly distributing airflow to each branch duct 233, and each of the branch ducts 233 and the air supply duct 23 is provided with a solenoid valve 232.

[0034] Furthermore, a position detection component is provided on the inner wall of the outer casing 11, and the ventilation and heat dissipation system 2 also includes a main controller. The position detection component is electrically connected to the main controller, and the main controller is electrically connected to the solenoid valves 232 on each branch pipe 233 in a one-to-one correspondence, for controlling the opening and closing of the corresponding solenoid valves 232 according to the blocking status of the blocking block 258.

[0035] Furthermore, the position detection component includes multiple position sensors, each of which is respectively mounted on the inner wall of each level chamber via a bracket, and the detection end of each position sensor is set towards the lifting frame 256 of the corresponding level chamber, for detecting the lifting position of the lifting frame 256 to determine whether the blocking block 258 has completed the blocking of the stop block 2510. It should be noted that the main controller is also electrically connected to the controller of the fan 21 and the controller of the cooler 222 to achieve signal coordination. This is an existing control method, and this solution only uses it without going into too much detail about its structure and the principle of each, only for the convenience of implementing this solution.

[0036] Specifically, when the heat feedback actuator of a certain level chamber senses a high temperature, it drives the piston 253 inside the sealing cylinder 251 to move upward, thereby causing the lifting frame 256 and the sealing block 258 to move upward to the preset position of the sealing stop block 2510. When the position sensor of the corresponding level chamber detects the arrival signal of the lifting frame 256, it transmits the trigger signal to the main controller. After receiving the signal, the main controller immediately controls the solenoid valve 232 on the branch pipe 233 to open, namely the branch pipe 233 corresponding to the high-temperature level chamber and the branch pipe 233 of the adjacent level chamber above the high-temperature level chamber. In addition, the lowest branch... The solenoid valve 232 on pipe 233 remains open, while the solenoid valves 232 on the remaining branch pipes 233 are closed. When the temperature of this level chamber drops to a preset threshold, the heat feedback execution component drives the sealing block 258 to reset and move downward, and the lifting frame 256 resets synchronously. The position sensor detects the reset signal and transmits it to the main controller. The main controller controls the solenoid valves 232 to return to their initial state, that is, to close the solenoid valves 232 of the branch pipes 233 of the high-temperature level chamber and the adjacent level chambers above it, leaving only the solenoid valves 232 of the bottom branch pipes 233 open, so that the ventilation and heat dissipation system 2 returns to the normal layer-by-layer heat dissipation mode.

[0037] Furthermore, the top of the heat dissipation chamber is provided with a number of ventilation holes 14 in a ring array, so that the upward airflow can be discharged from the heat dissipation chamber through the ventilation holes 14.

[0038] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
