The radiator of the traditional transformer is mostly of fin structure and is fixedly arranged on both sides of the oil tank. When the transformer needs to be arranged in a narrow space or buried underground, the heat dissipation effect of the radiator is seriously limited, which leads to the easy occurrence of high temperature overload of the transformer. CONTENT OF THE UTILITY MODEL

[0011] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example
[0012] This application relates to a transformer with an adjustable radiator position, such as... Figures 1-4 As shown, the transformer includes a vertically arranged oil tank 1 for support. The oil tank 1 contains an iron core and windings. A removable tank cover is arranged on the top of the oil tank 1. High and low voltage terminals and a pressure relief valve 4 are arranged on the upper part of the tank cover. An interference-blocking enclosure 5 is fitted on the upper part of the low voltage terminals. Support rods 7 are symmetrically arranged at the bottom of the oil tank 1. Casters 6 for movement are symmetrically arranged at the lower end of the support rods 7, which facilitates the transportation and movement of the transformer. The radiators 3 are no longer fixed on both sides of the transformer, but adopt a split structure, that is, the radiators 3 and the oil tank 1 are detachably connected. The radiators 3 and the oil tank 1 are connected by a pipeline 2. The pipeline 2 has a channel for the flow of insulating oil, so that the insulating oil can circulate between the oil tank 1 and the radiator 3 to achieve the heat dissipation function.
[0013] The radiator 3 can be appropriately adjusted to suit the needs of the installation environment. When the transformer is placed in a narrow space, the radiator 3 can be moved to a relatively spacious location. When the transformer is buried underground, the radiator 3 can be placed above ground to ensure heat dissipation. Through the split structure design, the radiator 3 can be flexibly adjusted according to the installation environment, improving the adaptability of the transformer. The flexible adjustment of the radiator 3 position ensures that the radiator 3 can fully exert its heat dissipation function regardless of the environment in which the transformer is placed, effectively avoiding high temperature overload. The detachable design of the radiator 3 makes it easier and faster to clean, repair or replace it. The flexible adjustment of the radiator 3 position also provides more possibilities for the layout of the transformer and helps to improve the overall aesthetics.
[0014] The radiator 3 is a key component, and its structural design plays a crucial role in heat dissipation. The radiator 3 includes a back plate 11, fins 9, and a pipe 8. The back plate 11 is a plate-like structure that serves as a support, providing sufficient strength and rigidity to ensure the stability of the radiator 3 in various use environments. The back plate 11 is uniformly and spacedly arranged with fins 9 on one side. These fins 9 are the main heat dissipation elements of the radiator 3.
[0015] The fins 9 are thin plate-like structures with hollow interiors. This design increases the heat dissipation area, facilitating sufficient heat exchange between the insulating oil and the external air. The shape, size, and spacing of the fins 9 can be optimized according to specific heat dissipation requirements to achieve the best heat dissipation effect.
[0016] Between the fins 9, there are two horizontally arranged pipes 8 that serve as communication channels. The pipe 8 at the upper part of the fins 9 is an oil inlet pipe for introducing hot insulating oil from the transformer into the radiator 3. The hot insulating oil enters the hollow cavity inside the fins 9 and comes into contact with the outer surface of the fins 9.
[0017] The pipe 8 at the lower part of the fins 9 is an oil outlet pipe for returning the cooled insulating oil back to the transformer. When the hot insulating oil flows inside the fins 9, it exchanges heat with the external air, transferring heat to the air and thus achieving cooling. The cooled insulating oil flows back to the transformer along the oil outlet pipe, continuing to participate in the operation of the transformer.
[0018] The structural design of this radiator 3 allows the insulating oil to enter the fins 9 along the oil inlet pipe and efficiently exchange heat with the external air. The hollow thin plate-like structure of the fins 9 and the uniform and spaced arrangement ensure that the insulating oil can fully contact the air, improving the heat dissipation efficiency. Meanwhile, the communication function of the pipe 8 enables the insulating oil to circulate between the radiator 3 and the transformer, forming a closed heat dissipation system.
[0019] The radiator 3 achieves efficient and flexible heat dissipation through the clever combination of the back plate 11, fins 9, and pipe 8. The position of the radiator 3 can be flexibly adjusted according to the installation environment, while the structural design of the radiator 3 ensures that the insulating oil can be fully cooled, effectively avoiding high-temperature overload conditions of the transformer.
[0020] To meet the expansion needs and spatial arrangement flexibility of the radiator 3, special design considerations have been made for the connecting pipeline 2 between the radiator 3 and the oil tank 1. The pipeline 2 is preferably a corrugated flexible hose with good flexibility and stretchability. The unique corrugated structure of the corrugated flexible hose gives the pipeline 2 good flexibility and stretchability, allowing the radiator 3 to have greater freedom in spatial arrangement.
[0021] The flexible characteristic of the corrugated hose allows the radiator 3 to be installed and adjusted at different positions relative to the oil tank 1, whether in a narrow space or in a situation where other equipment or structures need to be avoided, the corrugated hose can easily bend and twist to adapt to the layout requirements of the radiator 3.
[0022] At the same time, the stretchability of the corrugated hose also provides additional advantages in space arrangement. When the radiator 3 needs to be moved or adjusted, the corrugated hose can stretch and contract with the movement of the radiator 3, maintaining the connection between the radiator 3 and the oil tank 1, ensuring smooth circulation of insulating oil between the radiator 3 and the oil tank 1.
[0023] In addition, the corrugated hose also has good oil resistance and corrosion resistance, can withstand long-term immersion in insulating oil and external environmental erosion, ensuring the reliability and service life of the pipeline 2. By using a corrugated hose with good flexibility and stretchability as the connecting pipeline 2 between the radiator 3 and the oil tank 1, the expansion requirements and space arrangement flexibility of the radiator 3 are met.
[0024] In order to ensure the stability of the transformer radiator 3 in actual use and facilitate installation, as well as safety during transportation, the present application has made careful consideration in the design and packaging of the radiator 3. In order to facilitate the wall hanging fixing operation of the radiator 3, the back plate 11 of the radiator 3 of the present application is arranged with hanging pieces 10 around the periphery. These hanging pieces 10 are made of a strong and durable material, which can ensure the stability and reliability of the radiator 3 when hanging. The upper part of the hanging piece 10 is provided with a waist-round type hanging hole 12. This design not only makes the hanging piece 10 adapt to different sizes and shapes of fixing supports, but also provides a certain adjustment range, which is convenient for installation personnel to adjust the position of the radiator 3 according to actual needs.
[0025] Through the waist-round type hanging hole 12, the radiator 3 can be easily hung on the wall or other supporting structure without the need for additional fixing parts or tools, greatly simplifying the installation process and improving work efficiency. At the same time, the design of the waist-round type hanging hole 12 also increases the universality of the radiator 3, making it can be used in different installation environments.
[0026] In order to ensure the safety of the radiator 3 during transportation, the present application uses a strap to fix the radiator 3 on the upper part of the support rod 7. The strap is made of high-strength, wear-resistant material, which can firmly bind the radiator 3 on the support rod 7, preventing it from shaking or falling off during transportation. In addition, in order to further reduce the probability of damage caused by bumps during transportation, a cloth pad with a buffering effect can be added between the radiator 3 and the oil tank 1 and the support rod 7. The cloth pad is made of soft and shock-absorbing material, which can effectively absorb the impact and vibration during transportation, protecting the radiator 3 from damage.
[0027] In use, the position of the radiator 3 in the transformer of the present application is adjustable, and the method of use is simple and flexible. When installing or adjusting the transformer, first, the optimal position of the radiator 3 is determined according to the actual installation environment and the heat dissipation requirement, then the radiator 3 is fixed at the appropriate position by adjusting the length and bending degree of the corrugated hose, ensuring that the corrugated hose connecting the radiator 3 and the oil tank 1 is tightly connected without leakage, after that, the power supply of the transformer is turned on to make it run normally. During the running process, the insulating oil in the oil tank 1 is heated, enters the inside of the fin 9 of the radiator 3 through the oil inlet pipe, exchanges heat with the outside air, and then flows back to the oil tank 1 through the oil outlet pipe to form a closed heat dissipation cycle.
[0028] The position of the radiator 3 can be flexibly adjusted according to the actual environment to ensure that it is in full contact with the outside air, improving the heat dissipation efficiency. No matter where the transformer is installed, the optimal heat dissipation effect of the radiator 3 can be guaranteed to effectively avoid the overload of the transformer due to high temperature. The position-adjustable design of the radiator 3 makes the transformer can be normally installed and used in narrow space or special environment, which greatly enhances the adaptability of the transformer and widens its application range. The position adjustment of the radiator 3 and the use of the corrugated hose make the installation process of the transformer more simple and convenient. At the same time, when the radiator 3 needs to be cleaned, repaired or replaced, it only needs to be simply adjusted or disassembled, which greatly reduces the maintenance difficulty and cost. The corrugated hose has good oil resistance and corrosion resistance and can withstand the immersion of insulating oil and the erosion of the external environment for a long time, which ensures the connection reliability between the radiator 3 and the oil tank 1 and reduces the failure caused by the aging or damage of the pipeline 2.
