Abstract

The invention discloses an inductor, which comprises a magnetic core and a winding; the magnetic core comprises a middle magnetic core body and side magnetic core bodies connected to the two sides ofthe middle magnetic core body; the winding is wound on the middle magnetic core body; the middle magnetic core body is a ferrite core; and the side magnetic core bodies are iron powder cores. Under the condition of ensuring that the magnetic core has good magnetic conductivity, the problem that in the prior art, the local temperature is too high due to the fact that magnetic losses are concentrated in air gaps of the magnetic core and magnetic lines of force cut a heat dissipation metal water channel is solved.

Description

technical field [0001] The invention relates to the technical field of magnetic components, in particular to an inductor. Background technique [0002] The inductance used in the resonant network of the power transmission system of the on-board charger is a resonant inductor, and the core material of the resonant inductor is mostly ferrite. To prevent magnetic saturation, an air gap is usually placed on the core. As a result, the magnetic loss of the resonant inductor is concentrated in the air gap, resulting in an excessively high local temperature of the resonant inductor, which is not conducive to the heat dissipation of the entire resonant inductor, and the magnetic force lines generated by the air gap will also cut the water channel and generate heat. In addition, the resonant inductor is usually filled with heat-dissipating glue in the cavity for heat conduction, which will not only increase the volume of the resonant inductor, resulting in a decrease in power density...
