Abstract

Exemplary embodiments are directed to a heat exchanger system for transformers or reactors having at least one coil being cooled by gaseous fluids circulating around the transformer. The system having an enclosure that houses the transformer and the at least one coil, where flow of cooling gaseous fluid passes over the coil and is heated by the heat of the transformer or reactor the heated gas is directed to pass over a thermosiphon heat exchanger which dissipates the heat to a cooling media.
