Oil-immersed transformer shell with efficient heat dissipation function

The utility model relates to the field of transformer equipment, and discloses an efficient heat dissipation oil-immersed transformer shell which comprises an outer shell body, air inlet barrels are fixedly arranged in the middles of the two side walls of the outer shell body, and a bottom draft fan is fixedly arranged in the middle of the bottom end of the outer shell body. Side air inlet fans are fixedly arranged on the two side walls of the outer shell and located in the air inlet barrel, and a transformer body is arranged in the outer shell. According to the transformer, external air is rapidly sucked into the shell through the suction fan on the side wall of the outer shell, meanwhile, heat dissipated during working of the transformer can be rapidly discharged from the interior of the shell through cooperation with the suction fan at the bottom, and therefore the efficient heat dissipation effect is achieved; and dust and impurities can be effectively prevented from entering the shell to influence the he
