PURPOSE: A cooling structure of a transformer is provided to improve heat dissipation and cooling performance by improving the structure of the cooling iron core of a transformer. CONSTITUTION: A yoke part is formed in the top and lower part of a cooling iron core plate. The yoke protrusion is formed in one side of the yoke part. A heat dissipation hole pole(30) is formed between a winding and the yoke protrusion. A cooling iron core(10) is formed by laminating the cooling iron core plate in parallel. A heat dissipation groove(20) is formed by laminating the cooling iron core in parallel. The heat dissipation groove comprises a horizontal heat dissipation groove and a vertical heat dissipation groove. A fixing unit(40) is inserted into the joint hole of the cooling iron core in order to clinch the cooling iron core.
