Low-voltage high-current high frequency water-cooled transformer

The utility model discloses a low-voltage high-current high frequency water-cooled transformer. The water-cooled transformer is characterized in that: a magnetic core of the transformer adopts an ultracrystalline soft magnetic material and takes annular shape; an auxiliary side winding of the transformer includes a plurality of copper rods; after passing through the magnetic core, the copper rods are welded on bus plates that are arranged at left and right sides of the magnetic core and double as a support base of the transformer; the magnetic core is clamped between two bus plates and a certain gap is reserved among the bus plates and the magnetic core; in order to improve the radiating effect of the transformer, the bus plates at the leading-out ends of the auxiliary side windings of the transformer at the left and right sides of the magnetic core and the bus plates at the center tap of the auxiliary side winding are respectively welded with water-cooled radiating copper tubes; and in order to increase radiating area and promot radiating effect, each copper tube takes annular shape and is wound on three bus plates in inner and outer rings so that the temperature during the normal work of the transformer is maintained at a lower level, which is beneficial to reducing the size of the transformer and improving the performance.
