Iron core structure with good heat dissipation

The utility model relates to the technical field of iron cores, in particular to an iron core structure with good heat dissipation, which comprises a panel iron core, a middle iron core and a back plate iron core, and heat dissipation round holes are uniformly arranged on the panel iron core, the middle iron core and the back plate iron core. According to the iron core structure, the heat dissipation circular holes are formed in the panel iron core, the middle iron core and the back plate iron core, and the connecting heat dissipation grooves are formed in the middle iron core and the back plate iron core, so that the heat dissipation effect of the iron core structure can be improved; the panel iron core and the middle iron cores, the middle iron cores and the middle iron cores and the back plate iron core are inserted and connected into the inner sides of the heat dissipation grooves through the connecting protrusions, and then bolts are inserted into the inner sides of the positioning holes, so that connect
