[0001] This utility model relates to the field of transformer heat dissipation, and more particularly to a heat dissipation device for transformers. Background Technology

[0002] Transformer cooling refers to the effective dissipation of heat generated by a transformer during operation through certain technical means and devices, in order to maintain the transformer temperature within a safe range and prevent overheating from causing equipment damage or performance degradation. Transformer cooling devices are systems or equipment used to achieve the function of cooling transformers. The selection of transformer cooling devices depends on specific application requirements, environmental conditions, and cost considerations. When designing a transformer cooling system, engineers usually take into account a variety of factors to ensure that the equipment can operate stably and reliably under various working conditions.

[0003] In the prior art, the requirements for transformers in data centers, medical equipment, or avionics equipment are not limited to high efficiency, but also require small size, low noise, and the ability to adapt to high-temperature working environments. Existing transformer heat dissipation devices often cannot meet these conditions at the same time, especially when space is limited and efficient heat dissipation is required. Therefore, this application provides a heat dissipation device for transformers to meet the requirements. Utility Model Content

[0023] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0025] Reference Figure 1 - Figure 5 A heat dissipation device for a transformer includes: a heat dissipation part 2, which is detachably mounted on the transformer body 1. The heat dissipation part 2 includes: a housing 9; multiple fan bodies 8, which are mounted inside the lower part of the housing 9; multiple heat pipes 5, which are evenly mounted inside the upper part of the housing 9; heat dissipation fins 3, which are mounted on the housing 9; and multiple telescopic heat dissipation fins 6, which are evenly mounted on both sides of the housing 9.

[0026] The telescopic heat dissipation fin 6 is an electrically telescopic heat dissipation fin 6. The temperature inside the outer casing 9 is detected by a temperature sensor, thereby adjusting the extension and retraction of the telescopic heat dissipation fin 6.

[0027] The outer casing 9 is the main frame of the entire device, used to house and protect all internal components. The casing 9 is designed in a streamlined shape to facilitate airflow, reduce wind resistance, and improve heat dissipation efficiency. The casing 9 is equipped with an air inlet 14 and an air outlet 13 to ensure smooth airflow.

[0028] The fan body 8 adopts a low-noise design and accelerates the heat transfer speed by forcing airflow to improve heat dissipation efficiency. The fan body 8 is located close to the air inlet 14, which is conducive to introducing cool air.

[0029] Heat pipe 5 is responsible for quickly transferring the heat generated by the transformer to the heat sink fins 3, reducing the temperature difference between the heat source and the heat sink surface, and improving the heat transfer efficiency.

[0030] The heat dissipation fins 3 are designed to be horizontally inclined and streamlined at the top to facilitate airflow. By increasing the surface area in contact with the outside air, the heat dissipation fins 3 enhance natural convection heat transfer, and can effectively dissipate heat even without the assistance of the fan body 8.

[0031] The retractable heat dissipation fins 6 correspond to the air outlet 13. These retractable heat dissipation fins 6 can dynamically adjust their unfolded state according to actual heat dissipation needs. When higher heat dissipation capacity is required, the retractable heat dissipation fins 6 unfold to increase the effective heat dissipation area; conversely, they retract to reduce dust entering the interior of the outer casing 9.

[0032] The outer casing 9 has an air outlet 13 for use with the telescopic heat dissipation fins 6, and an air inlet 14 for use with the fan body 8; a filter screen 10 is installed inside the air inlet 14.

[0033] The main function of the air outlet 13 is to exhaust the hot air processed by the heat dissipation device to the external environment. By setting the air outlet 13 near the telescopic heat dissipation fins 6, it is ensured that the hot air can be discharged smoothly and avoids accumulation inside the device. The design of the air outlet 13 takes into account the optimal airflow path to ensure smooth airflow and improve heat dissipation efficiency. With the dynamic adjustment of the telescopic heat dissipation fins 6, the heat dissipation effect can be optimized under different operating conditions. The reasonably designed air outlet 13 can reduce the resistance of airflow and increase the airflow speed, thereby further improving the heat dissipation efficiency.

[0034] The air inlet 14 is used to introduce cold air from the outside. Through the forced ventilation of the fan body 8, the cold air is sent into the device to help remove heat. The position and design of the air inlet 14 are matched with the operation of the fan body 8 to ensure that the fan body 8 can effectively draw in cold air and improve the heat dissipation effect.

[0035] The filter 10 can effectively block dust, impurities and other particles from entering the heat dissipation device. This helps to keep the inside clean and avoid dust accumulation that leads to a decrease in heat dissipation efficiency. By preventing dust and other contaminants from entering the inside of the housing 9, wear and corrosion of the internal components of the heat dissipation device can be reduced, and the service life of the equipment can be extended. The filter 10 is designed to be detachable, making it convenient to clean or replace it regularly to maintain its filtering effect.

[0036] The heat dissipation unit 2 also includes a support mesh plate 7, which is installed inside the housing 9 and is located above the fan body 8.

[0037] The support mesh plate 7 is located above the fan body 8 and is used to provide a stable support platform for the part of the transformer body 1 that extends into the housing 9, so as to avoid the transformer body 1 squeezing the fan body 8 and thus damaging the fan body 8. The support mesh plate 7 divides the internal space of the housing 9 so that each part is not affected during operation.

[0038] The heat dissipation section 2 also includes a second support mesh plate 4, which is installed inside the outer casing 9 and is in contact with the heat pipe 5.

[0039] One of the main functions of the support mesh plate 2 4 is to provide stable support for the heat pipe 5, ensuring that the heat pipe 5 does not shift or deform during installation and operation. The support mesh plate 2 4 can reduce the displacement of the heat pipe 5 during thermal expansion and contraction, improve the working stability and service life of the heat pipe 5, and prevent the heat pipe 5 from being deformed or damaged due to the weight of internal components or external impact.

[0040] The heat dissipation unit 2 also includes: a plurality of mounting parts 11, which are mounted around the housing 9; and fasteners 12, which are provided on the mounting parts 11 and are used to connect the mounting parts 11 and the transformer body 1.

[0041] By using the mounting part 11 and the fastener 12 together, the heat dissipation device can be firmly installed on the transformer body 1, avoiding loosening or falling off due to vibration or external force. This fixing method not only improves the stability of the heat dissipation device, but also ensures that the heat dissipation efficiency is not affected. The fastener 12 can be a screw, nut or other type of fixing device, which can be quickly assembled on site, saving time and labor costs. At the same time, it can be quickly removed when the heat dissipation device needs to be maintained or replaced, simplifying the maintenance process.

[0042] The heat dissipation fins 3 are horizontally inclined, and the upper part of the heat dissipation fins 3 is streamlined. The outer shell 9 is also streamlined, so that an arc-shaped air duct is formed inside the outer shell 9.

[0043] The streamlined design reduces airflow resistance, allowing air to flow more smoothly over the heat dissipation fins 3 and improving heat dissipation efficiency. Furthermore, this design helps reduce noise because turbulence is significantly reduced in the streamlined structure. The horizontally inclined design and streamlined shape of the heat dissipation fins 3 enhance natural convection heat transfer. The inclined fins 3 increase the contact area with air, thereby improving heat exchange efficiency. The streamlined design allows air to cover the heat dissipation fins 3 more evenly, ensuring rapid heat dissipation. The streamlined design of the casing 9 and heat dissipation fins 3 reduces wind resistance, meaning smoother airflow. Additionally, low wind resistance also helps reduce noise levels and improve the device's quietness.

[0044] The streamlined design of the outer casing 9 can form an arc-shaped air duct inside. The arc-shaped air duct can guide the airflow along a predetermined path, ensuring that the air can evenly cover all heat dissipation components, including heat pipes 5 and heat dissipation fins 3, thereby improving the overall heat dissipation effect. It not only optimizes the airflow path, but also improves the structural strength of the outer casing 9. Streamlined structures are generally more rigid than right-angle or acute-angle structures, which can reduce deformation caused by thermal expansion and contraction or external vibration. In addition, the streamlined design also has a better visual effect, making the entire heat dissipation device look more beautiful.

[0045] The main body of the fan 8 is a low-noise fan, and a temperature sensor is installed inside the outer casing 9.

[0046] The design of low-noise fans reduces the noise generated by the fans during operation, which is especially important for applications that require a quiet environment, such as data centers, inside medical equipment, or in avionics equipment. Low noise levels can improve user comfort and reduce interference, especially in work environments that require high concentration.

[0047] The temperature sensor is installed inside the housing 9 and can monitor the transformer's operating temperature in real time. By monitoring the temperature in real time, abnormalities can be detected in time to avoid equipment damage caused by overheating. In addition, the data from the temperature sensor can be used to intelligently control the fan speed and the extension and retraction of the heat sink 6 to achieve on-demand heat dissipation.

[0048] During use, the outer casing 9 is installed at the heat source of the transformer body 1 using the mounting parts 11 and fasteners 12. The power is turned on, the fan body 8 is started, and its normal operation is observed. The temperature sensor is checked to ensure that it accurately reads the temperature data and automatically adjusts the speed of the fan body 8 according to the temperature change. The extension and retraction function of the telescopic heat dissipation fins 6 is tested through the control system to ensure its normal operation. The operating temperature of the transformer is monitored in real time through the temperature sensor, and the heat dissipation strategy is adjusted according to the feedback. The dust at the air inlet 14 can be filtered through the filter screen 10 to avoid clogging the fan body 8. The fan body 8 accelerates the air flow inside the outer casing 9. Some hot air enters the upper part of the outer casing 9 and is dissipated through the heat pipe 5 and heat dissipation fins 3. At the same time, some hot air is discharged through the air outlets 13 on both sides of the outer casing 9.
