Abstract
The utility model discloses a high-performance compact disc (CD) type magnetic core, which comprises a plurality of chips. The magnetic core is formed by mutually and transversely stacking the chips, and an outer casing covers the integral surface of the magnetic core formed by transverse stacking. The magnetic core made of amorphous magnetically soft alloy strips has comprehensive performances of high strength, high hardness, wear resistance, corrosion resistance, high resistivity, high magnetic conductivity and low loss. The magnetic core structure formed by mutual transverse stacking gives full play to high efficiency and energy conservation of the amorphous materials to the greatest extent, thereby guaranteeing characteristics of fine high frequency response, high magnetic conductivity, high interference resistance, fine temperature stability, energy collectiveness, high safety performance and the like of the magnetic core. The high-performance compact disc (CD) type magnetic core is applicable to output filter reactors in high-frequency high-power switching power supplies and main transformers in uninterruptible power supplies.
Description
Technical field
The utility model is applied to the output filter reactor in the high-frequency high-power Switching Power Supply, the high-performance CD type magnetic core of the main transformer in the uninterrupted power supply.Mainly be that the structure of CD type magnetic core has been done improvement, effectively brought into play the superior electromagnetic performance of the magnetic core of amorphous alloy material.
Background technology
Amorphous alloy material has the excellent comprehensive performance, as high strength, high rigidity, wear-resisting, anti-corrosion, high resistivity, high magnetic conduction, low-loss.Because of its excellent performance, developed rapidly in recent years, particularly obtained on the output filter reactor in the high-frequency high-power Switching Power Supply, the main transformer in the uninterrupted power supply to use widely.Also be the critical material of high-technology fields such as power electronics, computer, communication, Aero-Space simultaneously, and be called as the new green environment protection material of 21 century.But make high-performance CD type magnetic core with amorphous alloy strips at present, mostly adopt winding method, form vertical lamination of " egg roll " shape, both be unfavorable for cutting processing, influence serviceability again, thus make that non-crystalline material had energy-efficient, high frequency response good, magnetic permeability is high, antijamming capability is strong, temperature stability is good, concentration of energy and the high advantage of security performance can not get bringing into play to greatest extent.But,, compare and improve as adopting silicon steel, permalloy, ferrite with the CD type magnetic core that traditional magnetically soft alloy band is made.
Summary of the invention
In view of above-mentioned present situation, the utility model provides a kind of high-performance CD type magnetic core, makes it have the cutting processing of convenience, can bring into play the superior electromagnetic performance of non-crystalline material again to greatest extent.
Technical solution of the present utility model is: a kind of high-performance CD type magnetic core, comprise chip body, and have the magnetic core that laterally is formed by stacking each other by a plurality of chip bodies, be inclusive with shell at the described magnetic core integral surface that laterally is superimposed as.
According to These characteristics, the related magnetic core that laterally is superimposed as is hollow runway shape structure, or the horseshoe-shaped structure body.
In this was novel, related shell was to select epoxide resin material for use.
Further, related chip body is the amorphous soft magnetic alloy material.
In a word, the high-performance CD type magnetic core that the utility model provides is made magnetic core because of having adopted the amorphous soft-magnetic alloy band, not only has the excellent comprehensive performance, as high strength, high rigidity, wear-resisting, anti-corrosion, high resistivity, high magnetic conduction, low-loss.And core structure by laterally being superimposed as mutually, help cutting processing, do not influence serviceability again, can also bring into play the energy-efficient of non-crystalline material to greatest extent, have that high frequency response is good, magnetic permeability is high, antijamming capability is strong, temperature stability is good, characteristics such as concentration of energy and security performance height.

Fig. 2 is another embodiment of Fig. 1.
Embodiment
Embodiment is further described the utility model below in conjunction with accompanying drawing.
See high-performance CD type magnetic core shown in Figure 1, comprise the chip body of making by amorphous soft-magnetic alloy material 1, in this is novel, have the magnetic core that adopts the hollow runway shape structure that a plurality of chip bodies 1 laterally are superimposed as each other.In addition, consider to giving full play to the electromagnetic performance of amorphous soft-magnetic alloy material excellence, and avoid not fall in the magnetic core work slag, therefore be inclusive with shell 2 at the magnetic core integral surface that laterally is superimposed as.The shell 2 of present embodiment is to select epoxide resin material for use.
In the present embodiment, the related magnetic core that laterally is superimposed as is the hollow runway shape structure that adopts.In addition, also can also can select the horseshoe-shaped structure body for use according to instructions for use.The making of the magnetic core of described horseshoe-shaped structure body is on the magnetic core basis of hollow runway shape structure, utilizes the line cutting to cut off the magnetic core that the back forms two horseshoe-shaped structure bodies; Or directly utilize line to be cut into the magnetic core of single horseshoe-shaped structure body.
The processing technology of the utility model high-performance CD type magnetic core is, with the Fe-based amorphous alloy band of 40 micron thickness each other lamination become blank, heat-treat then, be cut into through dipping lacquer, oven dry, warp again and need the racetrack of specification structure, utilize the epoxy resin embedding to form thin outer crust at last, guarantee the performance of the electromagnetic performance of amorphous alloy material excellence.
Make the chip body 1 of magnetic core in the utility model, employed amorphous soft-magnetic alloy is a novel soft magnetic material of new generation, utilize flash set technology, with the molten steel of fusion cooling rate quench cooled with per second 1,000,000 degree, a solidification forming is the metal sheet band of 20～40 micron thickness, has the excellent comprehensive performance.
