Isolated evaporative cooling transformer

The invention relates to an isolated evaporative cooling transformer, and the transformer comprises an iron core, a coil, a clamping part, a pull plate, an oil tank, a shielding net, an evaporator, acondenser and a fan, wherein a cooling medium is stored in the evaporator, and the evaporator is provided with an inlet and an outlet and embedded into outwards-protruding thin layers of the top and the upper half portion of the side wall of the oil tank in the transformer; the iron core, the coil, the pulling plate and the clamping part are all immersed in transformer oil; and the condenser is ofa sheet type structure. According to the invention, the surface, flush with the inner wall of the oil tank, of the cooling area adopts the metal mesh plate as a shielding net, the metal mesh plate and the oil tank are grounded together, insulation and cooling are completely separated, and it is guaranteed that the insulation capacity is not reduced even if phase change happens to an evaporative cooling medium. 本发明涉及一种隔离式蒸
