Problems solved by technology

[0002] During the use of power transformers, the current is electromagnetically converted through the primary and secondary windings and the silicon steel sheet iron core, and part of the electric energy will be converted into useless heat energy. If this heat is not dissipated as soon as possible, it will affect the performance of the transformer and the safety of electricity. Cause adverse effects, the power transformer currently being produced or used in China, the radiator is an iron flat tubular part that surrounds the box and communicates with the transformer oil in the box, because of its small heat dissipation section, and because of the aluminum The thermal conductivity is three times that of iron, so the current iron radiators of power transformers have poor heat dissipation performance due to the shortcomings of structure and materials, which is not conducive to saving energy and exerting the potential of power equipment operation; at the same time, research on metal materials shows that , the smooth aluminum surface has the characteristics of reflecting the infrared rays of sunlight, while iron has the characteristics of absorbing infrared rays, so the power transformer equipped with iron radiator in the open-air working environment in summer will also increase additional heat due to the sunshine factor , is not conducive to the heat dissipation of the equipment
[0003] The Chinese patent application number 201420575108.9 discloses a new type of combined aluminum heat sink suitable for power transformers, including aluminum heat sinks, aluminum ends, main flow pipes and spacers, and the two ends of the aluminum heat sink are respectively Connect the aluminum end, the aluminum end is fixed on the main flow pipe through the spacer sleeve, the aluminum end, the spacer sleeve and the main flow pipe are correspondingly provided with through holes for the circulation of heat dissipation oil, and the spacer sleeve passes through the sealing ring To achieve sealing, after a period of use, the sealing ring will age and oil will leak easily, but the existing welding tool cannot realize the welding of the cylindrical spacer sleeve on the main flow pipe
