The invention discloses a multi-mode cooling
system, which comprises a
transformer main body, a primary cooling loop and a secondary cooling loop, and is characterized in that the
transformer main body comprises a sealed shell, and an iron core, a winding and an immersed cooling liquid which are arranged in the sealed shell; the primary cooling loop comprises radiators on the front side and the rear side of the
transformer main body and a multi-needle-net type
ion wind radiating device; the secondary cooling loop comprises an
evaporator, a condenser, a water
evaporation cooling device and related connecting pipelines, the water
evaporation cooling device comprises a water tank at the top, a valve, a packing layer, an air draft fan and a receiving disc, when the load of the transformer is increased, the valve is opened to provide cooling water,
micro capillary pores of the packing layer are utilized to form a spraying opening for water
evaporation cooling, and the water evaporation cooling device is connected with the condenser. And the air draft fan is started to accelerate the air to flow from top to bottom. The cooling mode is selected according to the operation working condition of the transformer, the whole device does not need to additionally provide driving force,
refrigerant liquid can achieve self-driven circulation, and
energy consumption is reduced while stable work of the transformer is guaranteed.
