The size of transformers is becoming more and more compact. At the same time, the social environment has higher and higher requirements for the noise of transformer equipment. Conventional capacity ultra-high voltage power transformers use a large number of plate radiators as self-cooling heat dissipation equipment. In order to meet the heat dissipation capacity requirements of transformers and adapt to the trend of miniaturization of transformers, the application of gooseneck structure plate radiators is becoming more and more widespread. With this structure of plate radiator, under the same height difference between the upper and lower oil pipes and the same number of plates, the gooseneck structure of the plate radiator increases the heat dissipation area compared with the conventional structure, has high heat dissipation efficiency, and can provide a larger heat dissipation capacity on the transformer of the same volume. While meeting the heat dissipation requirements of the transformer, the overall appearance and structure of the transformer can be made simpler, the product occupies less space, and the user's maintenance workload is lower.

This manufacturing method causes large resistance and slow oil flow when the transformer oil flows inside the gooseneck oil pipe, which ultimately affects the heat dissipation efficiency of the gooseneck structure plate-type radiator.
