Abstract
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.
Claims21
A cooling system for cooling a dielectric insulating fluid flowing through a transformer, the system comprising:
- a plurality of cooling tubes oriented in a substantially vertical manner, wherein each tube has a top opening and a bottom opening and, wherein the tubes are interconnected to form a bundle configuration;
- one or more distributor headers positioned between and in fluid communication with the transformer and the top openings of the cooling tubes;
- one or more collector headers positioned between and in fluid communication with the transformer and the bottom openings of the cooling tubes;
- and
- a plurality of vertical air channels formed by the interconnected bundle configuration.
A method for cooling dielectric insulating fluid flowing through transformers, the method comprising:
- circulating dielectric insulating fluid downwardly from a transformer through one or more vertical tubes;
- and
- circulating an air stream upwardly through vertical air channels formed by the interconnection of the tubes to cool the dielectric insulating fluid.
