Background

The inductor is a common anti-interference element in an electronic circuit, a magnetic ring and a coil are arranged in the inductor, a large amount of heat energy can be generated in the use process, and the increase of the internal temperature of the inductor becomes a main problem for restricting the design of the inductor. The inductor in the prior art is often cooled by natural air, and once the volume of the inductor is too large, the heat of the inductor is not easy to dissipate, so that the temperature of the product is excessively increased; as the power requirements of customers on the whole machine are higher and higher, the heat dissipation requirements on the inductor are increased; however, conventional inductors do not have heat dissipation properties themselves.

The utility model patent CN211957377U provides an inductor with good heat dissipation effect. The circular radiating fins are arranged in the shell, so that the radiating efficiency of the radiator body is improved; however, the circular radiating fin sleeve is arranged on the outer side of the heat conducting rod, so that the volume of the inductor shell is enlarged, the glue filling amount is increased, and the magnetic core assembly sleeved with the coil cannot be fixed.
