Problems solved by technology

[0002]The filter is usually composed of a capacitor, an inductor and a resistor. The inductor is also an electromagnetic coil. On the insulating tube, when a current flows through the wire, a certain electromagnetic field will be generated around the wire, but the wire will generate heat when the current passes through the wire, and the electromagnetic field will be affected as the temperature rises, thereby affecting filter effect

Abstract

The invention provides a filtering magnetic core with high magnetic conductivity, wherein the filtering magnetic core comprises a base, a shell and a filtering piece; the base is provided with a heatdissipation fan; the shell is detachably connected to the base, a heat dissipation cavity is formed in the shell, a coil is wound around the outer portion of the shell, an air inlet and a ventilationopening which are communicated with the heat dissipation cavity are formed in the shell, and the ventilation opening is communicated with an air suction opening of the heat dissipation fan; the filtering piece is detachably arranged between the ventilation opening and the air suction opening, and a dust collecting groove with an opening facing the ventilation opening is formed in the filtering piece. An air suction port of a heat dissipation fan is communicated with the heat dissipation cavity; air flow enters the shell from the outer side of the shell, so heat generated by the coil enters theheat dissipation cavity along with flowing of the air flow, the air flow with the heat in the heat dissipation cavity flows out of the shell through the heat dissipation fan to form circulation of the air flow, it is guaranteed that the heat generated by the coil can be taken away by the air flow, and the purpose of cooling the coil is achieved.

Description

technical field [0001] The invention relates to the field of filter technology, in particular to a filter core with high magnetic permeability. Background technique [0002] Filters are usually composed of capacitors, inductors and resistors. Inductors are also electromagnetic coils. The coils in the prior art are usually made of wires that are wound round by round on the insulating tube. When there is current flowing through the wires, it will A certain electromagnetic field is generated around this wire, but when the current passes through the wire, the wire will generate heat, and as the temperature rises, it will affect the electromagnetic field, thereby affecting the filtering effect of the filter. [0003] Therefore, it is necessary to develop a filter core with high permeability to solve the above technical problems. Contents of the invention [0004] The purpose of the present invention is to provide a filter core with high magnetic permeability, so as to cool dow...
