Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to an iron-silicon-aluminum inductor. Background Technique

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only impedes the change of current. If the inductor is in a state without current passing through, when the circuit is switched on, it will try to impede the current from flowing through it; if the inductor is in a state with current passing through, when the circuit is switched off, it will try to maintain the current unchanged. Inductors are also called chokes, reactors, and dynamic reactors; among them, iron-silicon-aluminum inductors use iron-silicon-aluminum magnetic powder cores, which can eliminate the adverse factors brought by using gap ferrite magnetic rings: First, the magnetic flux density of ferrite is equal to or less than 0.5T, which is even less than half of that of iron-silicon-aluminum alloy. Therefore, under the same volume, the energy storage of ferrite is also lower than that of iron-silicon-aluminum alloy; Second, in addition, the saturation magnetic flux density of ferrite drops significantly under high-temperature conditions, while high-temperature conditions have no significant impact on iron-silicon-aluminum; Third, ferrite materials have the characteristic of rapid saturation. If the safety current value is exceeded, it may cause the overall collapse of the inductor performance, while iron-silicon-aluminum materials have soft saturation characteristics and can withstand higher current values.

[0003] Among them, a Chinese patent for an iron-silicon-aluminum inductor, application number <2019210>31109.6>, includes an iron-silicon-aluminum shell, copper wire, and an iron-silicon-aluminum cover; the materials of the iron-silicon-aluminum shell and the iron-silicon-aluminum cover are both iron-silicon-aluminum; the iron-silicon-aluminum shell is oblate, and it has a circular groove. There is a cylinder in the middle of the circular groove, and the first foot hole and the second foot hole are arranged on the edge of the groove; the beneficial effect of the utility model is that: the traditional iron-silicon-aluminum inductor is a copper coil wound around a ring, while this design uses a copper coil wound around the cylinder in the middle of the iron-silicon-aluminum, and there is an iron-silicon-aluminum cover to cover it; its structure can achieve automated production, improve production efficiency, and save labor costs; and it has a smaller volume, better heat dissipation and energy storage.

[0004] The above patent improves the traditional iron-silicon-aluminum inductor through design, but there are still certain deficiencies: in this iron-silicon-aluminum inductor, by winding the copper coil around the cylinder in the middle of the iron-silicon-aluminum to achieve the purpose of facilitating production, but the cylinder is located inside the iron-silicon-aluminum, and the operating space is narrow and not easy to operate. After being damaged, it is not easy for the staff to repair and replace the copper coil on the cylinder. Therefore, we propose an iron-silicon-aluminum inductor. Content of the Utility Model
