Large-current potting inductor and manufacturing method

The invention relates to the technical field of electrical components, and provides a large-current encapsulation inductor and a manufacturing method thereof, an insulating interlayer nested on a magnetic core middle column is creatively arranged, on one hand, the magnetic core middle column and a coil winding are isolated by the insulating interlayer, and the insulating requirement is met; on the other hand, an insulating interlayer is utilized, a first heat conduction layer is arranged between the outer side wall of the magnetic core middle column and the insulating interlayer in a spaced mode, and a second heat conduction layer is arranged between the inner side wall of the coil winding and the insulating interlayer in a spaced mode and used for conducting internal heat; meanwhile, the first heat conduction layer is communicated with the second heat conduction layer through a through hole in the insulating interlayer, and the second heat conduction layer is communicated with the insulating packaging layer
