Description

Technical Field

[0001] This utility model relates to the field of transformers, specifically to a transformer housing structure with efficient heat dissipation. Background Technology

[0002] In power systems, transformers, as core equipment, undertake critical tasks such as voltage transformation and power distribution. Transformers generate a significant amount of heat during operation. If this heat cannot be dissipated in a timely manner, the internal temperature of the transformer will continuously rise. Excessive temperature can damage critical components such as the transformer's insulation materials and windings, affecting its electrical performance and service life, and may even lead to safety accidents such as short circuits and fires. Therefore, efficient heat dissipation capabilities are crucial for the stable operation and reliable functioning of transformers, directly impacting the power supply quality and security of the power system.

[0003] However, traditional transformer casing structures have many shortcomings in terms of heat dissipation. On the one hand, the heat dissipation methods of traditional casings are relatively simple, mostly relying on natural convection, which has low heat dissipation efficiency and cannot meet the heat dissipation requirements of modern power systems for high loads and long-term operation of transformers. On the other hand, the heat dissipation structure design of traditional casings is not reasonable enough, with limited heat dissipation area, making it difficult to quickly and effectively transfer the heat generated inside the transformer to the surrounding environment. These shortcomings make transformers prone to local overheating during operation, accelerating equipment aging, increasing maintenance costs, and in severe cases, may even cause power outages, negatively impacting various fields such as industrial production and residential life. Therefore, we propose a transformer casing structure with high-efficiency heat dissipation. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a transformer housing structure with efficient heat dissipation, thus solving the above-mentioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a transformer housing structure with high-efficiency heat dissipation, including a housing, a positive heat dissipation pipe, and a heat dissipation assembly. Two sets of high-voltage output terminals are provided on both sides of the top of the housing, and two sets of low-voltage output terminals are provided on the front of the housing away from the high-voltage output terminals. A support frame is provided on the right side of the top of the housing.

An inner oil groove is provided inside the positive heat dissipation pipe. A heat dissipation assembly is provided on the front of the housing, and the heat dissipation assembly includes a connecting seat, a line clip terminal, a heat dissipation plate, a cooling fan, and connectors. Connecting seats are provided at both ends of the front of the housing, and a line clip terminal is provided inside the connecting seat. A heat dissipation plate is provided at the bottom end of the line clip terminal.

[0009] Preferably, the inner side of the support frame is provided with an oil tank, the output end of the oil tank is provided with an oil pipe, and the output end of the oil pipe extends into the interior of the housing.

[0010] Preferably, the top of the positive heat dissipation pipe is provided with multiple sets of heat dissipation grooves at equal intervals, and the heat dissipation grooves are in an inverted trapezoidal structure that is recessed into the positive heat dissipation pipe.

[0011] Preferably, the heat sink has multiple cooling fans arranged at equal intervals inside, and the bottom of the heat sink has a connector.

[0012] Compared with the prior art, this utility model provides a transformer housing structure with efficient heat dissipation, which has the following beneficial effects:

[0013] 1. This device features a front heat dissipation pipe on the front of the casing. Its flat front structure increases the heat dissipation area. The internal oil groove stores and guides the flow of cooling oil to remove heat. The inverted trapezoidal heat dissipation groove on the top further increases the contact area with air, accelerating heat dissipation. At the same time, the side heat dissipation pipes on both sides also adopt a flat side structure to assist in heat dissipation from the side, achieving all-round heat dissipation. In addition, multiple sets of cooling fans are equidistantly arranged inside the heat dissipation plate in the heat dissipation component to actively accelerate airflow and quickly remove heat. This multi-directional and multi-layer heat dissipation design makes the heat dissipation efficiency far higher than that of traditional technology, effectively avoiding performance degradation and failure of transformers due to overheating and extending their service life.

[0014] 2. This device, through the line clip terminals located inside the connector in the heat dissipation assembly, can orderly organize and fix the internal or external lines of the transformer.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The transformer housing structure has a high efficiency for heat dissipation, including a housing 1, a positive heat dissipation pipe 6, and a heat dissipation assembly 7. Two sets of high-voltage output terminals 3 are provided on the top two sides of the housing 1, and two sets of low-voltage output terminals 4 are provided on the front of the housing 1 away from the high-voltage output terminals 3. A support frame 5 is provided on the top right side of the housing 1. The positive heat dissipation pipe 6 is provided on the front of the housing 1, and the positive heat dissipation pipe 6 has a flat front structure. An inner oil groove 601 is provided inside the positive heat dissipation pipe 6. The heat dissipation assembly 7 is provided on the front of the housing 1. The heat dissipation assembly 7 includes a connecting seat 701, a line card connector 702, a heat dissipation plate 703, a cooling fan 704, and a connector 705. The connecting seats 701 are provided at both ends of the front of the housing 1. The line card connector 702 is provided on the inner side of the connecting seat 701. The heat dissipation plate 703 is provided at the bottom end of the line card connector 702.

[0022] Furthermore, two sets of side heat dissipation pipes 2 are provided on both sides of the housing 1, and the side heat dissipation pipes 2 have an overall flat structure. The flat structure of the side heat dissipation pipes 2 greatly increases the contact area between the transformer side and the air. Traditional transformers rely on natural convection or a small number of heat sinks to dissipate heat on a limited surface area, which is inefficient. However, the side heat dissipation pipes 2 in this design allow more air to contact the surface of the heat dissipation pipes, accelerating the heat transfer speed. When the transformer generates heat during operation, the side heat dissipation pipes 2 can quickly dissipate the heat into the surrounding air. Together with the front heat dissipation pipes 6, they form an all-round three-dimensional heat dissipation system, effectively reducing the overall temperature of the transformer and ensuring that the transformer maintains a good heat dissipation state during long-term operation, avoiding performance impact or shortened service life due to local overheating.

[0023] Furthermore, the bottom end of the high-voltage output terminal 3 extends into the interior of the housing 1, and a tower-shaped insulating sleeve is provided on the outside of the high-voltage output terminal 3. The tower-shaped insulating sleeve greatly enhances the insulation performance. The tower-shaped structure design increases the creepage distance, effectively preventing current leakage along the insulation surface and reducing the risk of electrical accidents caused by poor insulation. Whether in a humid environment or under high-voltage conditions, the tower-shaped insulating sleeve can reliably isolate the high-voltage output terminal 3 from the outside world, ensuring the personal safety of operators, while ensuring the stable operation of the transformer, avoiding equipment damage caused by leakage, and improving the safety and reliability of the entire power system.

[0024] Furthermore, the bottom end of the low-voltage outgoing terminal 4 extends into the interior of the housing 1, and a tower-shaped insulating sleeve is provided on the outside of the low-voltage outgoing terminal 4. Equipping the low-voltage outgoing terminal 4 with a tower-shaped insulating sleeve greatly improves the insulation reliability. Although low voltage is less dangerous than high voltage, if the insulation is faulty, it may still cause accidents such as short circuits and electric shocks, affecting the normal operation of equipment and personnel safety. The unique structure of the tower-shaped insulating sleeve can effectively prevent the intrusion of dust, moisture, etc., enhance insulation performance, and extend service life. Moreover, it can adapt to different working environments. Whether indoors or outdoors, it can provide stable and reliable insulation protection for the low-voltage outgoing terminal 4, ensure the safe transmission of low-voltage circuits, and guarantee the stable operation of the power system.

[0025] Furthermore, an oil tank 501 is provided on the inner side of the support frame 5, and an oil pipe 502 is provided at the output end of the oil tank 501. The output end of the oil pipe 502 extends into the interior of the housing 1. The cooling oil stored in the oil tank 501 is transported to the interior of the transformer housing 1 through the oil pipe 502. The cooling oil has good thermal conductivity and can quickly absorb the heat generated inside the transformer. Compared with air, oil can carry more heat and has a higher heat transfer efficiency. This oil circulation cooling method can more accurately dissipate heat from key heat-generating parts inside the transformer, effectively reduce the internal temperature, and reduce the decline in electrical performance caused by excessive temperature. At the same time, the oil circulation cooling system is relatively stable and can work continuously for a long time, providing reliable heat dissipation guarantee for the stable operation of the transformer and improving the overall performance and service life of the transformer.

[0026] Furthermore, the top of the positive heat sink 6 is provided with multiple sets of heat dissipation grooves 602 at equal intervals, and the heat dissipation grooves 602 are inverted trapezoidal structures that are recessed into the positive heat sink 6. The inverted trapezoidal structure of the heat dissipation grooves 602 greatly increases the heat dissipation surface area of ​​the positive heat sink 6. When the transformer generates heat and it is transferred to the positive heat sink 6, the larger heat dissipation area means that more heat can be quickly transferred to the surrounding air. At the same time, the design of the heat dissipation grooves 602 being recessed into the positive heat sink 6 makes the heat transfer path inside the heat sink more reasonable, which helps the internal heat to be conducted to the surface of the heat dissipation grooves 602 more quickly. The multiple sets of heat dissipation grooves 602 distributed at equal intervals further optimize the heat dissipation effect. They can disrupt the flow of the surrounding air and form local air turbulence, allowing the air to contact the heat dissipation surface more fully and carry away more heat. This design comprehensively improves the heat dissipation capacity of the positive heat sink 6, effectively reduces the temperature of the transformer, ensures its stable operation, and avoids performance degradation and failure caused by overheating.

[0027] Furthermore, multiple cooling fans 704 are equidistantly arranged inside the heat sink 703, and a connector 705 is provided at the bottom of the heat sink 703. The multiple cooling fans 704 equidistantly arranged inside the heat sink 703 actively enhance airflow. When the transformer generates heat, the cooling fans 704 rotate rapidly, accelerating the airflow speed around the heat sink 703, which can quickly remove heat and greatly improve heat dissipation efficiency. Moreover, the equidistant distribution ensures the uniformity of heat dissipation and avoids local heat accumulation. The connector 705 at the bottom of the heat sink 703 provides great convenience in installation and maintenance. It allows the heat dissipation component 7 to be easily and quickly connected and disassembled with other components. Whether in the initial installation of the transformer or when the heat dissipation component needs to be inspected or replaced later, it can significantly reduce the difficulty of operation, save time and labor costs, and improve the maintainability and operating efficiency of the entire transformer system.

[0028] Structural Description:

[0029] Shell: The shell is the external main structure of the transformer, acting like a sturdy protective cover that encloses the various internal components. It not only provides overall physical support for the transformer, ensuring the stable layout of the internal components, but also possesses a certain degree of protection, resisting the impact of external environmental factors on the internal components. The shell is typically made of materials with good mechanical strength and insulation properties to ensure the safety and reliability of the transformer during operation.

[0030] Side heat dissipation pipes: The side heat dissipation pipes are located on both sides of the housing, with an overall flat side structure. This unique shape design aims to significantly increase the contact area with air, thereby enhancing the heat dissipation effect. The side heat dissipation pipes are an important component of the transformer's heat dissipation system. Through the pipe walls, they exchange heat with the surrounding air, promptly dissipating the heat generated by the transformer during operation, effectively helping to reduce the overall temperature of the transformer and ensuring its stable operation.

[0031] High-voltage output terminal: The high-voltage output terminal is a key structure of the transformer used to output high voltage current. Its bottom end extends into the shell to connect with the high-voltage circuit inside the transformer. The tower-shaped insulating sleeve on the outside is an important protective structure to ensure its safe operation. The tower-shaped insulating sleeve can significantly enhance the insulation performance, increase the creepage distance, prevent leakage and discharge in high-voltage environments, and ensure the safety and stability of the high-voltage output terminal when transmitting high voltage.

[0032] Low-voltage output terminal: The low-voltage output terminal is responsible for the low-voltage current output of the transformer. Its bottom end also extends into the shell and is connected to the internal low-voltage circuit. The tower-shaped insulating sleeve on the outside can effectively prevent dust, water vapor and other substances from entering, enhance the insulation effect, avoid short circuits, electric shock and other accidents caused by insulation problems, ensure the safe transmission of electrical energy in the low-voltage circuit, and ensure the stable operation of the power system.

[0033] Support frame: Located inside the transformer, the support frame plays an important role in supporting and fixing other components. It provides a stable structural foundation for the entire internal structure of the transformer, ensuring that each component maintains its relative position during operation and will not shift due to factors such as vibration or collision, thereby ensuring the normal operation of the transformer.

[0034] Oil Tank: Located inside the support frame, the oil tank is a container for storing cooling oil. As a crucial medium for transformer cooling, the cooling oil is properly stored in the tank. The tank provides a stable storage space for the cooling oil, ensuring its continuous cooling function during transformer operation.

[0035] Oil pipe: The oil pipe connects to the output end of the oil tank and extends into the inside of the transformer housing. Its main function is to transport the cooling oil in the oil tank to the parts inside the transformer housing that need to be cooled, thus creating a circulation channel for the cooling oil. This allows the cooling oil to flow inside the transformer, effectively absorbing and carrying away heat, and achieving efficient heat dissipation.

[0036] Positive heat sink: The positive heat sink is the heat dissipation structure on the front of the transformer, with multiple sets of heat dissipation slots evenly spaced on its top. The positive heat sink dissipates the heat generated by the transformer through heat exchange with the surrounding air, and is an important component of the transformer's heat dissipation system. It has an internal oil groove, allowing cooling oil to flow within the sink, further enhancing the heat dissipation effect.

[0037] Inner oil groove: The inner oil groove is located inside the positive heat pipe and is the channel through which the heat dissipation oil flows inside the positive heat pipe. Through the inner oil groove, the heat dissipation oil can come into more direct contact with the positive heat pipe, accelerate the transfer of heat from the inside of the transformer to the positive heat pipe, and then dissipate it into the surrounding air through the positive heat pipe, thereby improving the heat dissipation efficiency.

[0038] Heat dissipation grooves: The heat dissipation grooves are evenly distributed on the top of the positive heat pipe, forming an inverted trapezoidal structure that curves inward toward the inside of the heat pipe. This unique structural design greatly increases the contact area between the positive heat pipe and the air, creating a complex airflow as the air passes through the heat dissipation grooves. This prolongs the contact time between the air and the surface of the heat pipe, more effectively removing heat and significantly improving the heat dissipation capacity of the positive heat pipe.

[0039] Heat dissipation components: Heat dissipation components are a key part of the transformer heat dissipation system, bearing the dual responsibility of enhancing heat dissipation and managing wiring. Through the coordinated work of various components, they ensure efficient heat dissipation for the transformer, while optimizing the organization and fixation of internal and external wiring, thus improving overall maintainability.

[0040] Connector: The connector is part of the heat dissipation assembly and is located inside the heat dissipation assembly. It not only provides an interface for the connection between the heat dissipation assembly and other parts of the transformer, but also provides an installation position for the line clip terminals, allowing the line clip terminals to be securely mounted on the heat dissipation assembly, thus realizing the function of organizing and fixing the transformer lines.

[0041] Line clip connectors: Line clip connectors are located inside the connector base and are used to organize and secure the internal or external wiring of the transformer. By connecting the line clips to the line clip connectors, the wiring layout can be made more orderly, avoiding the damage caused by wires tangling or being squeezed together. This also makes it easier for staff to quickly identify and locate the wiring during inspections and maintenance, improving troubleshooting efficiency.

[0042] Heat sink: The heat sink is a key heat dissipation component in the heat dissipation system, playing a central role in the entire transformer cooling system. It has a large planar area, providing a broad platform for heat transfer and dissipation. Multiple cooling fans are evenly spaced inside. This layout design fully utilizes the space of the heat sink to achieve a comprehensive and uniform heat dissipation effect. The heat sink effectively absorbs and conducts heat through close contact or proximity to other heat-generating components of the transformer. Then, the cooling fans accelerate airflow, quickly dissipating the heat into the surrounding environment, thereby ensuring that the transformer always operates within a suitable temperature range and maintains stable operation.

[0043] Cooling fans: The cooling fans, evenly and equidistantly positioned within the heat sink, are the key power source for active heat dissipation. When the transformer generates heat during operation, the cooling fans quickly activate, their blades rotating at high speed. This rapidly stirs the air around the heat sink, creating a strong airflow that continuously carries away heat from the surface of the heat sink, significantly improving heat dissipation efficiency. The equidistant distribution design ensures uniform heat dissipation, preventing localized overheating and allowing the entire heat sink to efficiently and evenly dissipate heat. This effectively guarantees the stable operation of the transformer and prevents various malfunctions caused by overheating.

[0044] Connectors: Located at the bottom of the heat sink, the connectors are crucial structures for connecting and securing the heat sink components to other transformer parts. They allow for precise adaptation to the corresponding structures on the transformer, ensuring the heat sink is securely mounted and maintaining stability during operation. They prevent loosening due to vibration or other external forces. Furthermore, the connectors greatly facilitate installation and disassembly, simplifying operations during initial transformer assembly and subsequent maintenance and replacement of the heat sink components. This reduces labor and time costs and improves the maintainability of the entire transformer system.

[0045] Working Principle: First, the housing 1 serves as the external load-bearing structure of the entire transformer, providing a mounting base for other components. Two sets of high-voltage output terminals 3, located on both sides of the top of housing 1, are linked to the high-voltage circuit inside the transformer, achieving the effect of drawing out high-voltage electricity. The tower-shaped insulating sleeves on the outside of the high-voltage output terminals 3 further link with them, preventing high-voltage leakage and ensuring safe operation. Simultaneously, two sets of low-voltage output terminals 4, located on the front of housing 1 away from the high-voltage output terminals 3, are linked to the low-voltage circuit inside the transformer, achieving the effect of drawing out low-voltage electricity. The tower-shaped insulating sleeves on their outer sides also serve to prevent low-voltage leakage. The support frame 5 on the top right side of the housing 1 is connected to the oil tank 501 on the inner side and the oil pipe 502 extending into the housing 1 through the output end of the oil tank 501. This links the internal cooling oil circuit of the transformer, achieving the effect of supplying cooling oil to the inside of the transformer and assisting in internal heat dissipation. The front cooling pipe 6 on the front of the housing 1 has a flat front structure, which increases the heat dissipation area. The inner oil groove 601 inside the front cooling pipe 6 is linked to the cooling oil supplied from the oil tank 501 through the oil pipe 502, achieving the effect of storing and guiding the cooling oil to flow in the front cooling pipe 6 to remove heat. The top of the front cooling pipe 6 has multiple sets of inverted trapezoidal structures arranged at equal intervals and concave inward. The recessed heat dissipation groove 602, in conjunction with the air surrounding the positive heat dissipation pipe 6, increases the contact area between the air and the positive heat dissipation pipe 6, thereby accelerating heat dissipation into the surrounding air. Similarly, the heat dissipation component 7, located on the front of the housing 1, has connecting seats 701 at both ends that, in conjunction with the housing 1, secure the position of the heat dissipation component 7. The wiring clip terminals 702 inside the connecting seats 701, in conjunction with the internal or external wiring of the transformer, organize and secure the wiring, preventing messy wiring from affecting heat dissipation or causing safety hazards. The heat dissipation plate 703 at the bottom of the wiring clip terminals 702 contains multiple sets of cooling fans 704 arranged at equal intervals, which in turn in conjunction with the heat dissipation plate 703. The surrounding air is accelerated by the fan rotation, achieving the effect of quickly removing heat from the heat sink 703. The connector 705 at the bottom of the heat sink 703 is linked to other equipment or structures, achieving the effect of facilitating the installation, disassembly or secure connection of the heat sink component 7 to other components. The two sets of side heat sinks 2 set on both sides of the housing 1 have a flat side structure that also increases the heat dissipation area. They are linked to the air around the side of the transformer to achieve auxiliary heat dissipation from the side, working together with the front heat sink 6 to achieve an all-round and efficient heat dissipation effect. Through the linkage between these components, the transformer housing is finally efficiently cooled, ensuring the stable operation of the transformer.
