Description
Technical Field

[0002] From the lighting of light bulbs to the flickering of mobile phone screens, from the operation of home appliances to the rhythm of industrial production, electricity and transformers are everywhere. They serve us quietly and drive the progress of society. Transformers, as important equipment for power transmission, generate a lot of heat during operation. Overheating will affect the efficiency of the transformer and may even cause failures. Therefore, the transformer will dissipate heat. Traditional heat dissipation methods include natural heat dissipation and heat dissipation using fans. Natural heat dissipation has low cost but limited heat dissipation capacity. When using fans for heat dissipation, the fan is generally installed directly on the surface of the transformer but generally lacks a guide unit. Then, the fan generally only blows air to dissipate heat on a single surface. The blowing and heat dissipation area is limited, and the heat dissipation effect of the transformer is poor.

The terminal is connected to the transformer housing 1 and the primary coil 4 or the secondary coil 5 inside. The primary coil 4 is energized to generate an alternating magnetic field in the iron core 3, and then the secondary coil 5 generates an induced electromotive force, thereby realizing a change in voltage. A support shell 6 is provided in the middle of the lower end of the transformer housing 1, and a fan 7 is provided at the lower end of the support shell 6. The input end of the fan 7 is electrically connected to the output end of the external controller. The external controller The fan 7 is controlled to work, and the fan 7 blows air upward. A protective cover 9 is provided at the lower end of the fan 7 to protect the fan 7 from damage. The lower end of the support shell 6 is provided with evenly distributed water leakage holes 10. The water leakage holes 10 facilitate the discharge of rainwater inside the support shell 6. A conical cover 11 is provided at the lower end of the support shell 6. The water leakage holes 10 are all arranged in conjunction with the conical cover 11. The conical cover 11 covers the water leakage holes 10 to reduce leakage of wind. The lower surface of the transformer housing 1 is provided with evenly distributed heat dissipation strips 12. The wind will be blown to the bottom surface of the transformer housing 1 and the surface of the heat dissipation strips 12. The left and right sides of the transformer housing 1 are provided with evenly distributed heat dissipation fins 13. The heat dissipation fins 13 increase the heat dissipation surface area of the transformer housing 1.
[0021] The guide unit 8 is respectively arranged on the front and rear sides of the transformer housing 1. The lower ends of the guide units 8 are connected to the support shell 6. The guide units 8 include guide plates 81 and sealing plates 82. The guide plates 81 are evenly arranged on the front and rear sides of the transformer housing 1. The guide plates 81 corresponding to the transverse directions are a group. The ends of the same group of guide plates 81 away from the transformer housing 1 are all provided with sealing plates 82. The guide plates 81 are wavy guide plates. The wind enters the flow channel formed by the guide plates 81, the sealing plates 82 and the transformer housing 1 under the guidance of the support shell 6 and flows upward. The air and the transformer The transformer housing 1, the heat dissipation strip 12, the guide plate 81 and the sealing plate 82 are in contact to exchange heat and take away heat, thereby realizing heat dissipation of the transformer.

During operation, the heat generated by the transformer housing 1, the primary coil 4 and the secondary coil 5 is transferred to the transformer housing 1, and the transformer housing 1 naturally dissipates heat through its own surface and the guide plate 81, the heat dissipation strip 12 and the heat dissipation fin 13. At the same time, the external controller controls the fan 7 to work, and the fan 7 blows air upward, and the wind will be blown to the bottom surface of the transformer housing 1 and the surface of the heat dissipation strip 12.
