Abstract

The utility model discloses a water-cooled high frequency transformer which comprises a primary coil, a magnetic core and a secondary coil. The primary coil is wound on the magnetic core which is fixed on the secondary coil. The secondary coil is evenly distributed on the magnetic core circlewise in an array mode. The positive pole of the secondary coil is fixed on a positive pole copper plate. The negative pole of the secondary coil is fixed on a first negative pole copper plate. A copper bar is fixed on the first negative pole copper plate. The other end of the copper bar is fixed on a second negative pole copper plate. A first water-cooled tube is fixed on the first negative pole copper plate. A second water-cooled tube is fixed on the second negative pole copper plate. A positive pole water-cooled tube is fixed on the positive pole copper plate. The water-cooled high frequency transformer utilizes the water cooling to dissipate heat, has quick heat dissipation speed, and can meet the requirements of a spot welder for large current and high power of the high frequency transformer. The water-cooled high frequency transformer has the advantages of being small in volume, saving electricity, being acid resistant, alkali-proof and heat resistant.
