A Cooling Arrangement For Cooling A Transformer

Abstract: The disclosure relates to a cooling arrangement (1) for cooling a transformer (10) in a transformer tank (12), the cooling arrangement (1) comprises a transformer tank (12), to be at least partially filled with an electrically insulating fluid when in use, a transformer (10) having windings (16), at least one heat exchanger (18), and a fluid discharge device (20) arranged in the transformer tank (12), fluidly connected to the at least one heat exchanger (18), and a pump (22) in fluid communication with the at least one heat exchanger (18) and with the fluid discharge device (20). The fluid discharge device (20) comprises at least one Coanda effect fluid flow multiplier (21) configured to discharge the cooled fluid along a discharge axis (c) towards one or more of the windings (16) of the at least one phase leg (14) of the transformer (10).
