Description

Technical Field

[0001] The utility model belongs to the technical field of oil-immersed transformer components, and in particular relates to a wing-shaped sheet radiator. Background Art

[0002] With the rapid development of my country's economy and the rapid growth of manufacturing industry, the demand for electricity in various fields of my country is also increasing year by year, and the demand for power transformers is also increasing rapidly. Most of the existing transformers are the above-mentioned oil-immersed transformers, which are a new type of high-performance transformer with a more reasonable structure and better performance. Oil is used as the main insulation means of the transformer and the cooling medium of the transformer. When the power transformer is in operation, the internal windings, cores and other components will produce losses, which are converted into heat and transferred to the oil tank wall through the heat conduction and convection of the transformer oil, so that the temperature of the windings, cores, oil tank walls and oil surface will continue to rise, and the temperature rise will directly affect the life of insulating materials such as windings. Therefore, the temperature must be controlled within a certain range, and the use of radiators for heat dissipation is an indispensable and important component in the transformer. Plate-type heat sinks are widely used in oil-immersed transformers due to their advantages of simple manufacturing, convenient operation, safety and reliability. They are also the mainstream heat sinks used in transformers. Plate-type heat sinks have high heat dissipation efficiency, but as the power of the transformer continues to increase, the heat generated by the iron core becomes greater and greater, causing the transformer oil temperature to continue to rise. For every 6 degrees Celsius increase in the temperature of the transformer, the life of the insulation material of the core winding will be halved. However, the cost of developing new heat sinks is very high. Generally, the heat dissipation capacity of the radiator can only be increased by increasing the heat dissipation area and increasing the production cost.

[0003] At present, most oil-immersed transformers use a plate-type radiator, which is generally composed of an oil inlet pipe, an oil outlet pipe and a group of heat sinks connected between the oil inlet pipe and the oil outlet pipe. The heat sinks of existing traditional radiators are mostly rectangular plate-shaped structures. On such existing heat sinks, multiple oil channels for the flow of transformer cooling oil are provided. There is also a lot of technical information about the radiator in the existing Chinese patent literature, and a few of them are: CN219626440U (a fence-type aluminum alloy oil-cooled radiator for transformers), CN115295283A (a plate-type radiator device for transformers), CN112885575A (a fin-type radiator for transformers), CN213546078U (transformer radiator), etc. However, the structure of the above-mentioned plate-type radiator has the following problems: First, the heat exchange efficiency is poor, because the oil inlet pipe and the oil outlet pipe are connected Connected to the end of the transformer in the length direction, the oil inlet pipe brings the hot oil in the transformer into and distributes the hot oil to the heat sink assembled between the oil inlet pipe and the oil return pipe. However, in actual practice, the heat sink that is farther away from the transformer obtains less hot oil, so that the comprehensive heat exchange function of a group of heat sinks cannot be fully exerted, resulting in the heat dissipation efficiency not reaching a satisfactory level; secondly, it is easy to affect the transformer. Since the heat sink adjacent to the transformer is kept parallel to the transformer, the heat it emits can easily cause thermal radiation to the transformer, thereby affecting the heat dissipation of the transformer body itself; thirdly, the space requirement is high. Since the oil inlet pipe and the oil outlet pipe are both connected to the ends of the transformer in the length direction, the existing radiator is attached to one end of the transformer, which makes the overall size of the transformer larger and requires a larger space when in use. It cannot be used in working scenarios with narrow space, resulting in poor overall applicability.

[0004] In view of the above situation, it is necessary to reasonably improve the existing oil-immersed transformer radiator structure to solve the problems of poor heat exchange efficiency, easy heat radiation to the transformer, large size and high space requirement of the above radiator. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background. Utility Model Content
