The existing transformer mainly depends on a heat dissipation air duct which is arranged between windings and separated by supporting bars for heat dissipation. However, the provision of the heat dissipation duct in the transformer undoubtedly increases the overall circumferential volume of the entire transformer. To reduce circumferential volume, existing methods of operation are ways to reduce the width of the air duct. However, the overall volume of the finished product is increased greatly, and the heat dissipation efficiency is reduced.
Therefore, it is urgently needed to design a novel transformer which avoids the excessive increase of the circumferential volume on the basis of improving the heat dissipation efficiency.
