Transformer easy to dissipate heat

The invention relates to the technical field of transformers, in particular to a transformer easy to dissipate heat, which comprises a box body and an iron core and a winding which are arranged in the box body, a plurality of radiating fins are fixedly connected to the side wall of the box body, the radiating fins are wave-shaped, a rectangular frame is arranged on the sides, far away from the box body, of the radiating fins in a lifting manner through a lifting mechanism, and the rectangular frame is arranged in the box body. And a cleaning mechanism is arranged on the outer wall of the rectangular frame and corresponds to the position between every two adjacent cooling fins. Fallen leaves or floccules and the like adhered to the cooling fins can be automatically removed, so that the protective coatings on the cooling fins are prevented from being damaged by acidic substances generated after the adhered fallen leaves rot, the use performance of the cooling fins is ensured, and the transformer is easy to diss
