To address the internal overheating issues caused by increased capacity in oil-immersed transformers. this paper presents the design of a novel panel-type radiator. Based on the traditional bottom-blow air-cooled panel-type radiator. this design incorporates side baffles to prevent lateral airflow leakage and adds metal fins on the panel surface to enhance thermal performance. https://www.marcelovicente.com/product-category/treatment-additive/
