Description

Technical Field

[0001] This utility model relates to the field of transformer heat dissipation technology, specifically a transformer coil heat dissipation device. Background Technology

[0002] Transformer heat dissipation is crucial for ensuring stable performance. Depending on the transformer's power, operating environment, and cost, different heat dissipation methods can be employed. Natural cooling is suitable for small-power transformers, utilizing natural convection and radiation. Forced air cooling can be used for medium-power transformers or in poorly ventilated environments, enhancing airflow to accelerate heat dissipation. For high-power transformers, liquid cooling or heat pipe cooling technologies are more efficient, but they are more costly and require higher maintenance. A search revealed application number 202123344180.X, "A Transformer Coil Core Heat Dissipation Device," as a priori document for this utility model. This priori document utilizes induced draft fans and cooling fans to increase the airflow velocity on the outer surface of the iron core, thereby achieving efficient cooling of the iron core coil. However, a problem exists: specifically, the installation and use of the induced draft fans and cooling fans have stringent requirements, especially the cooling fans, which are installed on the inner wall of the transformer casing. If maintenance is required, the heat dissipation device becomes difficult to maintain, reducing its practicality. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a transformer coil heat dissipation device to solve the technical problems in the prior art where the installation and use requirements of transformer coil heat dissipation devices are harsh, making it inconvenient to use the heat dissipation device effectively and reducing its ease of use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a transformer coil heat dissipation device, comprising a transformer body and a coil, wherein multiple heat dissipation fins are arranged on the outer side of the transformer body, and a heat dissipation mechanism is arranged between adjacent heat dissipation fins, the heat dissipation mechanism comprising a first guide plate and a second guide plate, a cavity being formed between the first guide plate and the second guide plate, a throat cavity being formed at the center of the cavity, one side of the throat cavity being connected to the interior of the transformer body through a through hole, a mounting frame being arranged below the multiple heat dissipation fins, a turbine fan being arranged at the bottom of the mounting frame, and multiple through slots being opened on the bottom surface of the transformer body.

[0005] By adopting the above technical solution, the turbine fan is started to transmit high-pressure airflow into the cavity. The curved structure of the first and second guide plates guides the airflow. The airflow is pressurized through the throat cavity, increasing the airflow velocity and reducing the pressure inside the throat cavity. At the same time, the air containing heat inside the transformer body enters the cavity through the through hole due to negative pressure and is discharged from the top of the cavity, thus achieving heat dissipation.

[0006] Furthermore, the multiple heat sinks are arranged linearly at equal intervals, and all of them are rectangular plate-shaped structures.

[0007] By adopting the above technical solution, multiple heat sinks are arranged linearly at equal intervals, ensuring a uniform distribution of heat dissipation area. This layout maximizes the contact area between the heat sinks and the air, allowing heat to be transferred to the surrounding environment more effectively, thereby improving heat dissipation efficiency.

[0008] Furthermore, the multiple through slots are arranged linearly at equal intervals along the length of the transformer body, and the interior of the transformer body is connected to the outside through the through slots.

[0009] By adopting the above technical solution, it is ensured that all parts inside the transformer can exchange air evenly with the outside. This layout is conducive to the even and rapid dissipation of heat from all corners inside the transformer, preventing heat accumulation and local overheating.

[0010] Furthermore, the cross-sections of the first and second guide plates are curved, similar to the Venturi tube structure.

[0011] By adopting the above technical solution, the airflow can be accelerated. In the throat area, the airflow velocity is significantly increased, thereby enhancing the heat dissipation effect and allowing heat to be carried away from the transformer more quickly.

[0012] Furthermore, the mounting frame and multiple heat sinks are detachable, and the turbine fan is electrically connected to an external power source via a control center.

[0013] By adopting the above technical solution, great convenience and flexibility are provided. When the heat sink is damaged or needs cleaning, it can be easily disassembled and replaced, thereby reducing maintenance costs and time.

[0014] Furthermore, a baffle is provided above the heat sink, and the baffle is installed at an angle to guide rainwater.

[0015] By adopting the above technical solution, the baffle can effectively protect the heat sink from direct damage from falling objects above, reduce damage to the heat sink caused by accidental collisions, and thus extend the service life of the heat sink.

[0016] Furthermore, a support base is provided at the bottom of the transformer body to support the installation of the transformer body and to provide air intake space for the through slot.

[0017] By adopting the above technical solution, the support base provides a stable support for the transformer. The support base can ensure the stability and safety of the transformer, prevent it from tipping over or moving due to external factors, and thus ensure the normal operation of the transformer.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model uses a heat dissipation mechanism to start a turbine fan and transmit high-pressure airflow into the cavity. The airflow is guided by a curved guide plate. The airflow velocity is increased and the pressure inside the throat cavity is reduced by pressurizing the throat cavity. At the same time, the hot air inside the transformer enters the cavity through the through hole due to negative pressure and is discharged to the outside, thus achieving heat dissipation. Outside air also enters the transformer through the through slot, increasing the air flow velocity on the coil surface and further enhancing the heat dissipation effect. This eliminates the need to install a heat dissipation device inside the transformer, improves maintenance convenience, and accelerates the air flow velocity on the coil and heat sink surface, effectively improving heat dissipation efficiency.

[0020] 2. By setting up a baffle, this utility model can effectively protect the heat sink from damage caused by falling objects, reduce the risk of damage to the heat sink due to accidental collisions, and thus significantly extend the service life of the heat sink. This protective measure is crucial to ensuring the long-term stable operation of the heat dissipation system. At the same time, the inclined installation structure of the baffle not only enhances the stability of the structure, but also effectively guides rainwater. In rainy weather, this inclined setting allows rainwater to flow away smoothly and avoids accumulation on the mounting frame. This ensures that the heat sink and the entire heat dissipation mechanism can maintain good heat dissipation under any weather conditions, thereby maintaining the normal operation and stable performance of the transformer.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1:

[0031] A transformer coil heat dissipation device, such as Figures 1-4As shown, the transformer includes a transformer body 1 and a coil 2. Multiple heat sinks 3 are arranged on the outer side of the transformer body 1. A heat dissipation mechanism 5 is arranged between adjacent heat sinks 3. The heat dissipation mechanism 5 includes a first guide plate 501 and a second guide plate 502. A cavity 503 is formed between the first guide plate 501 and the second guide plate 502. A throat 504 is formed at the center of the cavity 503. One side of the throat 504 is connected to the interior of the transformer body 1 through a through hole 505. A mounting frame 506 is arranged below the multiple heat sinks 3. A turbine fan 507 is arranged at the bottom of the mounting frame 506. Multiple through slots 508 are opened on the bottom surface of the transformer body 1. When the turbine fan 507 is started, it... It transmits high-pressure airflow into the cavity 503, and uses the curved structure of the first guide plate 501 and the second guide plate 502 to guide the airflow. The airflow is pressurized through the throat cavity 504, which increases the airflow velocity and reduces the pressure on the inner wall of the throat cavity 504. At the same time, the air containing heat inside the transformer body 1 enters the cavity 503 through the through hole 505 due to negative pressure and is discharged from the top of the cavity 503 to achieve heat dissipation. Outside air enters the transformer body 1 through the through slot 508, which increases the airflow velocity on the surface of the coil 2 and achieves heat dissipation. This avoids the need to install a heat dissipation device inside the transformer body 1, improves the convenience of maintenance, and accelerates the airflow velocity on the surface of the coil 2 and the heat sink 3 to improve heat dissipation efficiency.

[0032] See Figure 1 , Figure 2 Multiple heat sinks 3 are arranged linearly at equal intervals, and all of them are rectangular plate structures. The equidistant linear arrangement of multiple heat sinks 3 ensures a uniform distribution of heat dissipation area. This layout maximizes the contact area between the heat sinks 3 and the air, allowing heat to be transferred to the surrounding environment more effectively, thereby improving heat dissipation efficiency. At the same time, the rectangular plate structure of the heat sinks 3 is not only stable and easy to manufacture, but also effectively increases the heat exchange area. The rectangular plate arrangement also facilitates airflow and reduces airflow resistance, allowing heat to dissipate more quickly, further improving heat dissipation performance.

[0033] See Figure 2 , Figure 3 Multiple through slots 508 are arranged linearly at equal intervals along the length of the transformer body 1. The interior of the transformer body 1 is connected to the outside through the through slots 508, ensuring that all parts inside the transformer can exchange air evenly with the outside. This layout is conducive to the uniform and rapid dissipation of heat from all corners inside the transformer, preventing heat accumulation and local overheating. At the same time, the connection between the interior of the transformer body 1 and the outside through the through slots 508 provides a continuous flow of fresh air to replace the heated air inside the transformer, which not only improves heat dissipation efficiency but also ensures the stable operation of the transformer and extends its service life.

[0034] See Figure 3 , Figure 4 The cross-sections of the first guide plate 501 and the second guide plate 502 are curved, similar to a venturi tube structure, which can accelerate the airflow. In the throat cavity 504, the airflow velocity is significantly increased, thereby enhancing the heat dissipation effect and allowing heat to be carried away from the transformer more quickly. At the same time, this curved structure also reduces the pressure on the inner wall of the throat cavity 504. By utilizing the negative pressure effect, the air containing heat inside the transformer body 1 is more effectively drawn into the cavity 503 and discharged, further improving the heat dissipation efficiency, optimizing the airflow path, and enhancing the performance of the heat dissipation device.

[0035] See Figure 1 , Figure 2 , Figure 3 The mounting frame 506 and multiple heat sinks 3 are detachable. The turbine fan 507 is electrically connected to an external power source through the control center, providing great convenience and flexibility. When the heat sinks are damaged or need cleaning, they can be easily disassembled and replaced, thereby reducing maintenance costs and time. At the same time, the turbine fan 507 is electrically connected to an external power source through the control center, ensuring stable power supply and reliable operation of the fan. This connection method facilitates remote control of the turbine fan 507 and timely adjustment of its working status to adapt to different heat dissipation needs. In addition, the electrical connection also facilitates fault diagnosis and maintenance of the turbine fan 507, improving the reliability and durability of the entire heat dissipation system.

[0036] Example 2:

[0037] See Figure 1 , Figure 2 , Figure 3 A baffle 6 is installed above the heat sink 3. The baffle 6 is installed at an angle to guide rainwater. The baffle 6 can effectively protect the heat sink 3 from direct damage from falling objects above, reduce damage to the heat sink caused by accidental collisions, and thus extend the service life of the heat sink. At the same time, the inclined installation structure of the baffle 6 not only optimizes the structural stability, but also effectively guides rainwater. In rainy weather, the inclined baffle can guide the rainwater to flow away smoothly, preventing rainwater from accumulating on the mounting frame 506, and ensuring that the heat sink 3 and the heat dissipation mechanism 5 always maintain a good heat dissipation effect.

[0038] See Figure 3 , Figure 4The bottom of the transformer body 1 is provided with a support base 4, which is used to support the installation of the transformer body 1 and provide air intake space for the through slot 508. The support base 4 provides a stable support for the transformer, which can ensure the stability and safety of the transformer and prevent it from tipping over or moving due to external factors, thereby ensuring the normal operation of the transformer. At the same time, the support base 4 also provides air intake space for the through slot 508, ensuring that outside air can smoothly enter the transformer through the through slot 508, improving the air circulation speed on the surface of the internal coils and achieving effective heat dissipation.

[0039] The implementation principle of this utility model is as follows: First, the turbine fan 507 is started, causing the turbine fan 507 to transmit high-pressure airflow into the cavity 503. At this time, the first guide plate 501 and the second guide plate 502 of the curved structure guide the airflow, and the airflow is pressurized through the curved structure and its throat 504, resulting in an increase in the airflow velocity in the throat 504 and a decrease in the pressure on the inner wall of the throat 504. At the same time, the air containing heat inside the transformer body 1 flows into the cavity 503 through the through hole 505 due to negative pressure. Until the air is discharged from the top of the cavity 503 to the outside, this principle can be referred to as the Venturi principle. At the same time, the outside air flows into the interior of the transformer body 1 through the through slot 508, thereby increasing the air flow speed on the surface of the internal coil and realizing heat dissipation of the coil 2. In this utility model, the form of installing a heat dissipation device inside the transformer body 1 is avoided, which improves the convenience of maintenance of the heat dissipation device in subsequent use. While increasing the air flow speed on the surface of the coil 2, the air flow speed on the surface of the heat sink 3 is also accelerated, thereby further improving the heat dissipation efficiency of the coil 2.
