Transformer structure

Abstract

The invention relates to a transformer structure, which comprises a shell, an inductance unit and a heat conduction layer; the shell is provided with an accommodating space, the inductance unit is arranged in the accommodating space and provided with a winding part and a magnetic core group, and the heat conduction layer is arranged between the inductance unit and the shell; wherein heat energy generated by the inductance unit is transmitted to the shell through the heat conduction layer so as to carry out heat dissipation and insulation separation. Through the transformer structure, the heat energy generated by the inductance unit is transmitted to the shell through the heat conduction layer arranged between the shell and the inductance unit so as to enhance the heat dissipation efficiency and reduce the temperature of the transformer, and meanwhile, through an electromagnetic interference protection layer formed by the wrapping of the metal shell, the electromagnetic interference generated by the transformer can be decreased and the influence of the transformer on the peripheral electronic devices can be reduced, therefore, the transformer is enabled to have both the advantages of excellent heat conductivity and electromagnetic interference reduction and the like.
