Oil tank heat dissipation module for transformer

The utility model provides an oil tank heat dissipation module for a transformer, and belongs to the technical field of transformer heat dissipation. The transformer oil tank heat dissipation outer frame structure solves the problems that an existing transformer oil tank heat dissipation outer frame structure is generally of an integral type, machining is difficult, installation is troublesome, machining is not facilitated, meanwhile, heat dissipation of the structure is generally conducted passively through heat dissipation fins, effective heat dissipation cannot be conducted on corners of anoil tank, heat dissipation is uneven, and heat dissipation efficiency is not high. The transformer air cooling heat dissipation module comprises a bent body, splicing structures are arranged on the two sides of the bent body, a ventilation hole is further formed in the bent body, the section of the ventilation hole is triangular, and a plurality of evenly-arranged heat dissipation teeth are further arranged on the inner
