Immersion type evaporative cooling mode is adopted in transformer. Evaporative- cooling medium is injected to oil tank. Being generated by energy consumption, heating of windings and magnet core of transformer, quantity of heat is transferred to the evaporative-cooling medium in the oil tank. Thus, temperature of the medium is raised. When the temperature reaches to saturation temperature corresponding to inner pressure, the evaporative-cooling medium in the oil tank is vaporized, so that circulation is formed: vaporized medium generates phase change to absorb heat, and condenser cools vaporized medium to change it back to liquid. Comparing with transformer, the oil immersion type transformer removes out oil conservator to make structure simple; possesses high current density to reduce material needed.
