Abstract
The water resistance load system comprises a water resistor, which includes a cylindrical base electrode with a bottom for storing a predetermined quantity of water while water is circulated through the cylindrical base electrode and a cylindrical main electrode penetrating in an insulated state through the center of the bottom and extending into the base electrode, and an electrode water cooling unit, which includes a radiator through which warm water drained from the water resistor is passed to the water resistor, and a water spray tube, a fan and an air guide for spraying water to the radiator, air cooling the surface of the radiator by the latent heat of evaporation of the sprayed water, and guiding generated steam to be discharged into a space.
