High-frequency transformation high-inductance high-permeability ferrite core with high heat dissipation efficiency

The high-frequency transformation high-inductance high-permeability ferrite magnetic core comprises a magnetic core body, wherein fifth mounting holes are formed in the two ends of the magnetic core body and are through holes; the central axis of each fifth mounting hole and the central axis of the magnetic core body are arranged in parallel, and a connecting column is arranged in each fifth mounting hole; the cross section of the magnetic core is of an annular structure; blowing structures are arranged at the upper and lower ends of the magnetic core; the air blowing structure comprises a second annular ring which is overlapped at the end part of the magnetic core; a motor fixing shell is arranged in the middle of each second annular ring. The side face of the motor fixing shell and the first annular ring are connected through a plurality of arc-shaped rods. When the magnetic core is used, the interior of the magnetic core can be rapidly cooled through the forehead air blowing structures arranged at the two
