The insulating fluid in power transformers doubles as a coolant. It is pumped through the transformer and also drawn through it by thermal siphoning. The warm coolant is then sent to a suitable cooler. In order to minimise the transformer footprint the decision was made, in a break from what could be considered to be the established standard solution utilising free-standing radiator banks which emit heat into the surrounding air, to utilise oil/water heat exchangers for the job of cooling the transformers.
