Description

High-efficiency transformer heat dissipation device Technical Field

[0001] This application relates to the field of transformer technology, and in particular to a high-efficiency transformer heat dissipation device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components include a primary coil, a secondary coil, and an iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Transformers work based on the principle of electromagnetic induction. When alternating current passes through the primary coil, it generates an alternating magnetic field in the iron core. This alternating magnetic field passes through the secondary coil, and according to the law of electromagnetic induction, an electromotive force is induced in the secondary coil. By adjusting the turns ratio of the primary and secondary coils, the transformer can raise or lower the voltage. For example, when the number of turns in the secondary coil is greater than the number of turns in the primary coil, the output voltage will be higher than the input voltage, and vice versa.

[0003] Traditional transformers, when operating under high loads, cannot quickly dissipate the heat generated inside, which can easily lead to overheating, affecting their normal operation and even shortening their service life. Moreover, the installation process of transformers and their heat dissipation systems is complex, and disassembling and replacing parts is time-consuming and labor-intensive, which is not conducive to daily maintenance and emergency repairs. Transformers in operation will generate a certain amount of vibration, and long-term use may cause internal parts to loosen or be damaged, affecting the stability and safety of the equipment.

[0004] Therefore, in response to the problem that traditional transformers, when operating under high loads, generate heat that is difficult to dissipate quickly, easily leading to overheating, and that the installation of transformers and their cooling systems is complex, with time-consuming and labor-intensive disassembly and replacement of components, an efficient transformer cooling device can be designed. This device utilizes a separately installable transformer body and cooling structure, and employs components such as fixing slots, threaded slots, and fastening screws to achieve quick assembly and disassembly, greatly facilitating equipment installation and maintenance. By installing a fan structure, air circulation is actively promoted, enhancing the cooling effect, while the design of the ventilation slots also improves air exchange efficiency, helping to reduce the temperature more effectively. Summary of the Invention

[0021] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Among the currently discovered feasible technologies, the following are described:

[0023] Transformers are indispensable devices in power systems. Their main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Transformers operate based on the principle of electromagnetic induction. When alternating current passes through the primary coil, it generates an alternating magnetic field in the iron core. This alternating magnetic field passes through the secondary coil and, according to Faraday's law of electromagnetic induction, induces an electromotive force in the secondary coil. By adjusting the turns ratio of the primary and secondary coils, the transformer can raise or lower the voltage. For example, when the number of turns in the secondary coil is greater than that in the primary coil, the output voltage will be higher than the input voltage; conversely, the output voltage will be lower than the input voltage. Transformers are widely used in modern industry and society. A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Transformers can be classified according to their application. Transformers are categorized into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, angle transformers, high-current transformers, excitation transformers, etc. Transformers are fundamental equipment for power transmission and distribution, widely used in industry, agriculture, transportation, urban communities, and other fields. There are approximately 17 million transformers in operation in my country, with a total capacity of about 11 billion kilovolt-amperes. Transformer losses account for about 40% of power transmission and distribution losses, indicating significant energy-saving potential. High-efficiency transformers are widely used in various applications requiring efficient energy conversion, such as industrial production, commercial buildings, and data centers. They can significantly reduce energy consumption, improve overall equipment operating efficiency, and reduce maintenance costs. High-efficiency transformers generate less heat during operation, have less environmental impact, and meet energy conservation and environmental protection requirements.

[0024] Under high-load operating conditions, the heat generated inside a transformer is difficult to dissipate quickly, leading to overheating, which in turn affects its normal operation and may even shorten its service life. Due to the compact internal structure and poor air circulation of transformers, traditional passive cooling methods such as natural cooling are often insufficient to cope with the large amount of heat accumulation under high loads. Furthermore, overheating accelerates the aging of insulation materials, further increasing the risk of failure. The installation process of traditional transformers and their cooling systems is complex, and disassembling and replacing parts is time-consuming and labor-intensive, hindering routine maintenance and emergency repairs. This complexity not only increases maintenance costs but may also lead to prolonged downtime, affecting production efficiency. For example, when inspecting or replacing certain internal components, it may be necessary to remove multiple connectors and protective devices, increasing operational difficulty and time consumption. Operating transformers generate vibrations, which, with prolonged use, may cause internal parts to loosen or become damaged, affecting equipment stability and safety. Especially in areas prone to earthquakes or where the surrounding environment experiences significant vibration, effectively reducing the impact of vibration on transformers is a pressing issue. The lack of effective vibration reduction measures not only shortens equipment lifespan but may also lead to safety accidents.

[0025] To effectively address the low heat dissipation efficiency of traditional transformers, this design incorporates an active cooling mechanism. Specifically, a fan system is installed beneath the transformer body, using a motor-driven shaft to rotate the fan blades, generating airflow to accelerate heat dissipation. Simultaneously, mounting brackets are fixedly connected to the upper sides of the support plate, with multiple ventilation slots arranged sequentially from bottom to top within the brackets. These slots increase air exchange efficiency, contributing to more effective temperature reduction. Furthermore, the entire device employs a separate design, allowing the transformer body and heat dissipation structure to be installed separately. This enables flexible configuration of the cooling system according to actual needs, further improving heat dissipation. Considering the inconvenience of traditional transformer installation and maintenance, this design particularly emphasizes improving ease of installation and maintenance. Components such as fixing slots, threaded slots, and fastening screws enable quick disassembly and assembly. This means that technicians can more easily and quickly complete related operations during routine maintenance or emergency repairs, reducing downtime and maintenance costs. For example, when replacing a component, simply loosening the corresponding fastening screws allows for easy removal, eliminating the need for complex disassembly as before. To address the insufficient vibration resistance of traditional transformers, this design incorporates a vibration damping system. Specifically, a fixing block is fixedly connected to the lower surface of the mounting plate. A damping groove is provided on the lower surface of the fixing block near the corner. The damping groove is equipped with a damping spring and an internal spring damper. These damping elements can effectively absorb and mitigate vibration energy, protect the transformer from vibration damage, and enhance the shock resistance of the equipment.

Two sets of light steel keels 2 are symmetrically installed on both sides of the lower surface of the transformer body 1.

The fixing groove 4 is opened at the front end of the upper surface of the light steel keel 2. The mounting groove 6 is opened in the center of the light steel keel 2. The mounting plate 7 for separating the transformer body 1 from the heat dissipation structure is slidably connected between the mounting grooves 6. Multiple sets of threaded grooves 8 for mounting the transformer body 1 on the mounting plate 7 are opened sequentially from left to right on both front ends of the upper surface of the mounting plate 7. The fixing groove 4 is provided with The fastening screw 3 is threaded into the threaded groove 8 for quick disassembly. A fixing block 11 is fixedly connected to the lower surface of the mounting plate 7. The lower surface of the fixing block 11 is provided with a shock-absorbing groove 12 near the corner. The shock-absorbing groove 12 provides space for the installation of the shock-absorbing device, which helps to reduce the impact of vibration on the transformer. A shock-absorbing spring 13 is provided inside the shock-absorbing groove 12. A spring damper is provided inside the shock-absorbing spring 13. A sliding block 14 is provided at the lower end of the shock-absorbing spring 13. The shock-absorbing spring 13 and the spring damper can effectively absorb and mitigate vibration energy. A base 15 is fixedly connected to the lower surface of the sliding block 14. A support plate 9 is provided through the center of the fixing block 11. The base 15 provides a stable foundation support, while the support plate 9 strengthens the overall structural rigidity.

[0028] Mounting brackets 10 are fixedly connected to the upper ends of both sides of the support plate 9. Multiple ventilation slots 16 are sequentially opened inside the mounting brackets 10 from bottom to top. The design of multiple ventilation slots 16 increases the airflow path and improves heat dissipation efficiency. Motors 17 are installed in the center of the cavity on the surface of the mounting brackets 10. A rotating shaft 18 is installed at the output end of the motor 17. The motor 17 drives the rotating shaft 18 to rotate. As the core power source of the fan system, it effectively promotes airflow. Multiple fan blades 19 are installed around the outside of the rotating shaft 18. A fixing plate 20 is fixedly connected to the mounting bracket 10 at the rear end of the motor 17. The fan blades 19 rotate around the rotating shaft 18 to generate airflow and accelerate heat dissipation. The fixing plate 20 ensures the stable installation of the motor 17 and prevents loosening or displacement caused by operation. Fixing screws 21 that are threaded to the mounting bracket 10 are symmetrically installed on both sides of the surface of the fixing plate 20. The fixing screws 21 ensure the tight connection between the components, improve the structural stability and durability of the entire device, and facilitate disassembly and maintenance.

[0029] In use, the transformer body 1 is first securely mounted on the mounting plate 7 using the light steel keel 2 and its components such as the fixing groove 4, threaded groove 8, and fastening screws 3. The mounting plate 7 is connected to the bottom support structure through the fixing block 11 on its lower surface. Once the equipment starts running, any vibration generated by the transformer will be absorbed by the damping spring 13 in the damping groove 12 in the fixing block 11 on the lower surface of the mounting plate 7 and the internal spring damper. When heat dissipation is required, the motor 17 starts, driving the rotating shaft 18 to rotate. Multiple sets of fan blades 19 mounted around the outside of the rotating shaft 18 rotate accordingly, generating airflow. The airflow generated by the fan flows through multiple sets of ventilation slots 16 opened sequentially from bottom to top inside the mounting bracket 10 on both sides of the support plate 9. These ventilation slots 16 increase the air exchange efficiency and help to dissipate heat more effectively, thereby keeping the transformer within a suitable operating temperature range.
