The schematic diagram of the magnetic piece for using.Fig. 4 is the detailed view of the magnetosphere that the magnetic piece of Fig. 3 includes.
First as shown in figure 3, magnetic piece 100 may include laminar structure, in the laminar structure,
Multiple magnetospheres 101 are laminated each other, and binding agent 102 can be filled respectively along the thickness side of each magnetosphere 101
To the through hole for penetrating each magnetosphere 101, so as to provide the bonding between magnetosphere 101 in laminar structure
Power.For example, binding agent 102 can pass through the through hole of filling magnetosphere 101 (rather than between magnetosphere 101
Layer) connecting magnetosphere 101 adjacent to each other.
Magnetosphere 101 can perform the function of stopping or concentrate electromagnetic wave in wireless charging device etc., and
Can use includes the thin film type metal band of amorphous alloy or nanocrystal alloys and is formed.In this feelings
Under condition, Fe- bases or Co- base magnetic alloys can be used as amorphous alloy.Fe- bases magnetic alloy can be used
Such as Fe-Si-B alloys and formed.With the content increase of the metal comprising Fe, saturation flux density
Can become higher.When the content of Fe is excessive, can be difficult to form amorphous alloy.Therefore, Fe
Atom percentage content can be 70% to 90%, when Si contents and total atomic percent of B content
Than for 10% to 30% when, can most preferably obtain amorphous alloy.In order to prevent such basis
Corrosion, can be by corrosion-resistant element that its atomic percent is such as Cr or Co in the range of 20%
It is added to basis, and as needed, also other a small amount of metallic elements can be included basic
In composition, to provide other characteristics as basis.
Next, in the example using amorphous alloy, for example, Fe- base nanometer crystal bodies can be used
Magnetic alloy.Fe- base nanometer crystal bodies magnetic alloy can be formed using Fe-Si-B-Cu-Nb alloys.
Magnetosphere 101 may also comprise soft magnetic material, and can by such as Mn-Zn- bases, Mn-Ni- bases,
Br- bases or Sr- based ferrite materials are formed.Additionally, these materials can be formed by nanocrystal powder.
In this case, as shown in figure 4, magnetosphere 101 can process (flake through thin slice
Treatment), being crushed to the structure of multiple fragment P with magnetosphere 101.Magnetosphere 101 this
The tile structure of sample can be caused to be formed in being electrically connected between magnetosphere 101 and partially disconnected, so as to
Contribute to reducing the intensity of vortex flow.
Meanwhile, arranging can be using general in this area to the binding agent 102 in the through hole of magnetosphere 101
Jointing material (for example, it is known that resinous principle) and formed, it is possible to use magnetic adjacent to each other can be made
Layer 101 physically bond and the materials that can chemically be combined with magnetosphere 101 etc. and formed.Make
For the embodiment, the glued construction of magnetosphere 101 can cause binding agent 102 to be arranged in magnetosphere 101,
And magnetosphere 101 adjacent to each other is in direct contact with one another, to improve the radiating work(of magnetic piece 100
Can, so as to reduce its thickness.
More particularly, in order to ensure as shown in Fig. 3, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9
Excellent screening ability, when multiple magnetospheres 101 are laminated each other, to be formed during magnetic piece 100, puts
Uneven material (for example, binding agent etc.) between multiple magnetospheres 101 can cause magnetic piece 100
Radiating efficiency reduce.May have about including the binding agent of conventional fluoropolymer resin etc.
The heat conductivity value of 0.2W/mK to 1W/mK.Even if in binding agent by the material with high heat conductance
In the case of formation, binding agent is likely to be difficult to the heat conductivity value with 2W/mK to 5W/mK.
By contrast, the magnetosphere 101 including metal tape etc. can have the thermal conductivity of 5W/mK to 20W/mK
Rate value, causes difference between the heat-sinking capability of uneven material big.
In the example of the magnetic piece 100 according to the embodiment, through hole may be formed in magnetosphere 101 simultaneously
And can replace significantly decreasing the binding agent 102 between magnetosphere 101 filled with binding agent 102
Amount.Therefore, the novel glued construction of magnetic piece 100 can be obtained.Such glued construction can be
Keep being significantly reduced while the firm integrated structure between magnetosphere 101 and be unfavorable for effectively dissipating
The region that the binding agent 102 of heat is occupied, so that it is guaranteed that the level of the heat-sinking capability of abundance.Additionally, magnetic
Property piece 100 thickness can reduce big as the region that the region that occupied by binding agent 102 reduces.
Because binding agent 102 is present in the through hole of magnetosphere 101, therefore binding agent 102 is positively retained at
Between magnetosphere 101.In order to supplement bonding strength, other adhesive material can be applied to magnetosphere
101.During filling through hole, a small amount of binding agent 102 also can be flowed in magnetosphere 101.
Meanwhile, during forming through hole in magnetosphere 101, method commonly used in the art can be used,
For example, using the machining of Drilling operation, pin processing or laser beam processing, it is possible to use chemistry
Etching.In this case, Fig. 3 shows the magnetic with the multiple through holes filled with binding agent 102
Layer 101, but a part for through hole can also be not filled with binding agent 102.In some instances, can be in list
Single through hole is only formed in individual magnetosphere 101.In the through hole that magnetosphere 101 is filled using binding agent 102
During, various types of methods can be used, for example, the magnetosphere 101 for being formed with through hole is soaked
Method, silk screen print method and spraying process in binder solution etc..
Fig. 3 also show the binding agent 102 of the through hole that one magnetosphere 101 of filling includes and may be formed at
The binding agent of the through hole that another magnetosphere 101 for being adjacent to one magnetosphere 101 with filling includes
In the 102 corresponding position in position.In other words, it is present in viscous in magnetosphere 101 different from each other
Mixture 102 can be connected to each other, magnetosphere 101 can directly contact be adjacent other magnetospheres 101 (and
Do not pass through binding agent 102), so as to be conducive to improving heat-sinking capability.However, as shown in figure 5, being
More firm and more firm glued construction is obtained, the viscous of the through hole that a magnetosphere 101 includes is filled
Mixture 102 also may be formed to be adjacent in another magnetosphere 101 of one magnetosphere 101 with filling and wrap
In the position that the position of the binding agent 102 of the through hole for including does not line up.
Fig. 6 and Fig. 7 the difference is that only bonding supporting layer 103 between magnetic with embodiment before
Between layer 101, therefore bonding supporting layer 103 will only be described.Bonding supporting layer 103 can be between multiple
Between magnetosphere 101, to be connected to binding agent 102, layer insulation structure may be provided at adjacent to each other
Between magnetosphere 101, so as to obtain the effect of the loss for reducing vortex flow.Bonding supporting layer 103 can make
Formed with the material of the matrix of such as traditional two-sided tape, so that magnetosphere 101 is bonded to each other, and
And may include such as PET film etc..
In the example of the embodiment, the binding agent 102 being present in magnetosphere 101 different from each other can
(with reference to Fig. 6) is formed in the position to correspond to each other of binding agent 102, or in order to improve magnetosphere 101
Between bonding force, fill the through hole that magnetosphere 101 includes binding agent 102 may be formed at
Filling is adjacent to the binding agent 102 of the through hole that another magnetosphere 101 of one magnetosphere 101 includes
The position that do not line up of position in (with reference to Fig. 7).
Next, Fig. 8 and Fig. 9 show that binding agent 102 is filled in the logical of bonding supporting layer 103
In hole (rather than in magnetosphere 101), so that magnetosphere 101 is bonded to each other, binding agent 102 and bonding
Supporting layer 103 can be referred to as bonding part.In the example according to each magnetic piece 100 of the embodiment,
The region occupied by binding agent 102 can be significantly reduced, so as to improve heat-sinking capability, and binding agent
102 can be not formed in the upper and lower surface of bonding supporting layer 103, or minimal amount of bonding
Agent 102 can be applied to magnetic piece 100, so as to reduce the thickness of each magnetic piece 100.In the reality
In applying the example of example, when can be provided with three or more magnetospheres 101 and can be provided with two or more
During multiple bonding parts, two or more bonding parts adjacent to each other may be formed at and wherein make binding agent
In 102 positions to correspond to each other (with reference to Fig. 8), or may be formed at wherein make binding agent 102 that
In this position not lined up, to increase the bonding force between magnetosphere 101 (with reference to Fig. 9).
It is similar to description before, during forming through hole in bonding supporting layer 103, can use
Conventional method, for example, can use the machining of Drilling operation, pin processing or laser beam processing,
Also chemical etching can be used.In this case, Fig. 8 and Fig. 9 are shown with filled with binding agent
The bonding supporting layer 103 of 102 multiple through holes, but a part for through hole can also be not filled with binding agent
102.In some instances, single through hole can only be formed in single bonding supporting layer 103.Make
In the example of the process that the through hole of bonding supporting layer 103 is filled with binding agent 102, can use various types of
The method of type, for example, the bonding supporting layer 103 for being formed with through hole is immersed in binder solution
Method, silk screen print method and spraying process etc..
As described above, can be made according to the exemplary embodiment of the disclosure, magnetic piece and wireless charging device
