Novel phase-shifting transformer heat dissipation structure capable of improving air cooling efficiency

The invention relates to the technical field of transformer heat dissipation, in particular to a novel phase-shifting transformer heat dissipation structure capable of improving air cooling efficiency, which comprises internal gas circulation ports arranged on the inner side of a transformer shell, and the internal gas circulation ports are uniformly distributed on the left side and the right side of the transformer shell. A vertical mixed gas circulation pipeline is installed on the transformer shell at each column of internal gas circulation ports, the internal gas circulation ports are distributed on the inner side of the mixed gas circulation pipeline, and a hemispherical gas circulation structure is correspondingly arranged at each internal gas circulation port and is installed in the mixed gas circulation pipeline; external gas circulation openings are formed in the portions, on the outer side of the hemispherical gas circulation structure, of the mixed gas circulation pipeline, an external gas circulat
