Heat dissipation transformer

The utility model discloses a heat dissipation transformer which comprises a transformer oil tank and a transformer body installed in the transformer oil tank, a heat dissipation cover is fixed to the top of the transformer oil tank, an evaporation cavity is formed in the heat dissipation cover, an airflow through hole set is arranged on the side face of the heat dissipation cover, and at least one set of heat conduction pipe fittings is installed on the heat dissipation cover. The bottom end of the heat conduction pipe penetrates through the bottom of the evaporation cavity and extends to the bottom of the transformer oil tank, and the top of the heat conduction pipe penetrates through the top of the evaporation cavity and extends above the evaporation cavity. The heat dissipation device has the beneficial effects that part of the heat conduction pipe fitting penetrates through the evaporation cavity, and the heat conduction pipe fitting penetrating through the evaporation cavity can be rapidly dissipated th
