This review systematically analyses advancements, challenges, and opportunities in cooling systems for power transformers. Oil-immersed transformers, widely used due to their superior insulation and effective cooling, require efficient thermal management to prevent overheating and ensure operational stability. This review evaluates key cooling strategies across oil-natural air-natural (ONAN), oil-natural air-forced (ONAF), oil-directed air-forced (ODAF), and oil-forced air-forced (OFAF) systems. It highlights innovations in radiator design, such as top-mounted radiators and chimney caps, and explores sustainable alternatives, including biodegradable esters, nanofluids, and hybrid ventilation methods. Advanced computational tools like Computational Fluid Dynamics (CFD) and artificial intelligence (AI), particularly neural networks, are identified as transformative for optimising cooling performance, predicting thermal behaviour, and enabling real-time monitoring. Despite progresses, challenges persist in radiator optimisation, airflow dynamics, and scalability of innovative cooling methods. By offering a comprehensive review and identifying critical areas for improvement, this study provides a foundation for developing cost-effective, reliable, and environmentally sustainable cooling systems, aligning with the growing demand for efficient energy infrastructure.<\/jats:p>","DOI":"10.3390\/en18051051","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T09:26:32Z","timestamp":1740129992000},"page":"1051","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Power Transformers Cooling Design: A Comprehensive Review"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2656-8337","authenticated-orcid":false,"given":"Sandra","family":"Sorte","sequence":"first","affiliation":[{"name":"TEMA-Centre for Mechanical Technology and Automation, Department of Mechanical Engineering, University of Aveiro (UA), Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"},{"name":"LASI-Intelligent Systems Associate Laboratory, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-4956-2744","authenticated-orcid":false,"given":"Andr\u00e9 Ferreira","family":"Monteiro","sequence":"additional","affiliation":[{"name":"TEMA-Centre for Mechanical Technology and Automation, Department of Mechanical Engineering, University of Aveiro (UA), Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"},{"name":"LASI-Intelligent Systems Associate Laboratory, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2386-0621","authenticated-orcid":false,"given":"Diogo","family":"Ventura","sequence":"additional","affiliation":[{"name":"TEMA-Centre for Mechanical Technology and Automation, Department of Mechanical Engineering, University of Aveiro (UA), Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"},{"name":"LASI-Intelligent Systems Associate Laboratory, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2663-6684","authenticated-orcid":false,"given":"Alexandre","family":"Salgado","sequence":"additional","affiliation":[{"name":"TEMA-Centre for Mechanical Technology and Automation, Department of Mechanical Engineering, University of Aveiro (UA), Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"},{"name":"LASI-Intelligent Systems Associate Laboratory, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6190-1238","authenticated-orcid":false,"given":"M\u00f3nica S.
