heal.abstract	Increase of temperature rise and hot spot values affects dramatically transformer aging and life expectancy. The present article investigates several improved designs of ONAN transformer cooling system by means of advanced numerical heat transfer-fluid flow model. Novel tank designs are examined in conjunction with other crucial parameters, as the number and location of the winding cooling ducts, so as to define the best geometry that ensures maximum efficiency of the transformer cooling system, with the aim of expanding transformer lifetime. © 2012 IEEE.	en
