[0002] As an important part of the power system, the stability and reliability of special transformers are crucial to the operation of the entire system. However, special transformers generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the temperature of the transformer will rise, which will in turn affect its performance and life. The traditional heat dissipation methods of special transformers mainly rely on natural heat dissipation and fan forced heat dissipation. Although natural heat dissipation and fan forced heat dissipation are simple, the heat dissipation effect is limited and it is difficult to meet the heat dissipation needs of high-load and high-efficiency special transformers. Utility Model Content

A self-cooling box 20 is installed at the bottom of the special transformer 10, a liquid infusion tube 30 is installed at the top of the special transformer 10, and a plurality of groups of cooling coils 40 in a square ring shape are installed on the outer wall of the special transformer 10; a plurality of heat dissipation fins 11 arranged evenly and equidistantly are installed on the outer wall of the special transformer 10, and the cooling coils 40 are arranged in the gaps between the heat dissipation fins 11; a hydraulic pump 21 is installed in the self-cooling box 20, and the liquid infusion tube 30 is L-shaped, and the outlet of the hydraulic pump 21 is The water end is connected to the water inlet end of the infusion pipe 30, and the top outer wall of the infusion pipe 30 is equipped with a branch pipe 31 that is the same number and connected to the cooling coil 40; the bottom of each group of cooling coils 40 is equipped with a return pipe 41 connected to the inside of the self-cooling box 20. Through the infusion pipe 30 on the top of the special transformer 10 and the branch pipe 31 connected thereto, the coolant in the self-cooling box 20 can be transported to the cooling coil 40 on the outer wall of the special transformer 10, so as to achieve uniform distribution and flow of the coolant and enhance the cooling effect. The heat dissipation fins 11 arranged evenly and equidistantly on the outer wall of the special transformer 10 increase the contact area between the special transformer and the air and improve the heat dissipation efficiency. The cooling coil 40 is arranged in the gap between the heat dissipation fins 11, so that the coolant can fully absorb the heat on the heat dissipation fins during the flow process, thereby enhancing the heat dissipation effect. The return pipe 41 connected to the inside of the self-cooling box 20 installed at the bottom of each group of cooling coils 40 realizes the recycling of the coolant.

[0031] Furthermore, a plurality of cooling fans 12 are installed on the outer wall of the special transformer 10. Each cooling fan 12 is fixedly installed on the surface of the cooling fins 11. The cooling fans 12 can actively blow air toward the cooling fins 11 to increase the air flow speed, thereby accelerating the heat dissipation.

[0032] A semiconductor cooler 23 is embedded in one end of the cooling box 20. The semiconductor cooler 23 has high cooling efficiency and can quickly reduce the temperature of the coolant, so that it can better play a heat dissipation role.

[0033] Specifically, the outer wall of the self-cooling box 20 is installed with an anti-collision shell 22, which is made of glass fiber reinforced plastic material and has a thickness of 3-6 mm. It is not only light and durable, but also can effectively protect the self-cooling box 20 from external impact and damage.

[0034] In addition, the cooling coil 40 is made of copper tube or stainless steel tube with a thickness of 0.5-1mm, which has good thermal conductivity and corrosion resistance, can ensure the unimpeded flow of the coolant, and resist the corrosion that may be caused by long-term operation. The inner ring wall of the cooling coil 40 fits with the outer wall of the special transformer 10, which can ensure that the heat exchange between the coolant and the outer wall of the special transformer is more sufficient.

[0035] The working principle of the self-cooling special transformer heat dissipation component is as follows: when the special transformer 10 is working, the hydraulic pump 21 in the self-cooling box 20 is started to extract coolant from the self-cooling box 20 and transport it through the water inlet end of the infusion pipe 30. The coolant is further evenly distributed to each cooling coil 40 through the branch pipes 31 installed on the infusion pipe 30, which are the same number and connected to the cooling coil 40. The coolant flows in the cooling coil 40. Since the cooling coil 40 is arranged in the gap between the heat dissipation fins 11, the coolant can fully absorb the heat on the heat dissipation fins 11. The heat dissipation fins 11 increase the contact area between the special transformer 10 and the air, improve the heat dissipation efficiency, and further help the special transformer 10 to dissipate heat. The cooled coolant flows back to the self-cooling box 20 through the return pipe 41 installed at the bottom of each group of cooling coils 40. The return pipe 41 ensures the recycling of the coolant, improves the cooling efficiency and reduces energy consumption.
