Heat exchanger system for dry-type transformers

摘要

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.

1. A heat exchanger system for transformers having at least one coil being cooled by circulating gaseous fluids, comprising:
an enclosure housing the transformer; a thermosiphon heat exchanger; and a fan disposed between the thermosiphon heat exchanger and the transformer is configured to blow the cooling fluid through a first closed loop arrangement against the transformer, wherein a cooling fluid within the enclosure and flowing around the coil is heated by the transformer in the first closed loop and passes over the thermosiphon heat exchanger, which dissipates the heat to an intermediate cooling fluid flowing in the thermosiphon heat exchanger of a second closed loop.
