Technical Field
The utility model relates to a radiator field especially relates to a welded structure of fin of gilled radiator for transformer.
Background
Transformers are essential power devices in the power industry. An oil-immersed transformer is a relatively wide variety of transformers used in various types of transformers. The conventional oil-immersed transformer is provided with a finned radiator to ensure the normal operation of the transformer. At present, the most common finned radiator generally comprises an upper oil collecting pipe, a lower oil collecting pipe and radiating fins, wherein an air release plug is arranged on the upper oil collecting pipe, and an oil release plug is arranged on the lower oil collecting pipe.
The finned radiator generates heat in the running process of the transformer, oil in the inner cavity of the transformer is cooled by the radiator and then is recycled to the inner cavity of the transformer to achieve the cooling effect, and the heat dissipation effect of the radiator can be directly influenced by the reasonability of the finned structural design of the radiator.
The existing finned radiator needs to weld the radiating fins and the oil collecting pipes during production, but the welding structure of the existing radiating fins and the oil collecting pipes can cause garbage accumulation at the corner parts of the joint points, the welding garbage is difficult to clean, and the welding garbage can enter the inner cavities of the radiating fins to influence the using effect of the radiator.
