Transformer coil form with built-in helical heat dissipation channel

Abstract

The utility model discloses a transformer coil framework of built -in spiral heat dissipation channel, including coil framework body, the coil framework body surface is set up and is used for winding wire slot of winding, the coil framework body surface is set up and is set up in the core hole array's spiral heat dissipation groove, and the coil framework body bottom side wall is fixedly connected with the terminal block, the spiral heat dissipation groove of the core hole inner side wall of the utility model forms the spiral heat dissipation channel, when the heat of transformer work produces, and hot air will flow in the spiral heat dissipation groove, because the spiral structure can increase the path and time of air flow, make the heat more fully radiate, improve the heat dissipation efficiency, the design of terminal block's terminal groove, jack and needle foot, the wire head connection and fixed of winding are convenient, also convenient with external circuit and connect, simplified installation and wiring process, make the wiring of winding more convenient, neat, convenient installation and maintenance, improve production efficiency.
