Title
(EN) System and method for cooling transformers
(ZH) 冷却变压器的系统和方法
Abstract
(EN) A system and method are provided for cooling transformers utilizing a fluid to air heat exchanger to cool dielectric fluid flowing through the transformer. The system includes multiple vertical cooling tubes in fluid communication with the transformer to cool the dielectric fluid. The tubes are configured to create vertical air passages such that the system utilizes natural convection air flow and thermal siphoning to cool the fluid.
