PFC inductance is sealed, the inductance can internally space be less while keeps good heat dispersion.
The utility model is realized by following technology：
A kind of three-phase embedding PFC inductance, including inductance body and shell, interior be provided with of the shell are not less than three size phases
Same accommodating chamber, the inductance body is in accommodating chamber；One end of the inductance body is electrically connected with lead-out wire, described to draw
Outlet is stretched to shell extension；Embedding has casting glue between the inductance body and accommodating chamber.
Further, the inductance body includes iron core and coil, and the coil is located at the both sides of iron core.
Further, the lead-out wire is located at the side of coil.
Further, it is connected with pad between the iron core and coil.
Further, the material of the iron core uses Fe-based amorphous alloy or iron-base nanometer crystal alloy.
Further, the spacing distance between the accommodating chamber is not more than 2cm.
Further, the material of the shell uses aluminium alloy.
The beneficial effects of the utility model：A kind of three-phase embedding PFC inductance of the present utility model, PFC inductance is directly put
Enter in accommodating chamber, and be potted in PFC inductance in metal shell completely by embedding；Because the radiating of casting glue is good, accommodate
The distance between chamber can be accomplished smaller, and need to only install once, save manpower and cost.

Illustrate embodiment of the present utility model below by way of specific instantiation, those skilled in the art can be by this theory
Content disclosed by bright book understands other advantages and effect of the present utility model easily.The utility model can also be by addition
Different embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints with answering
With, without departing from it is of the present utility model spirit under carry out various modifications or alterations.
It should be noted that structure, ratio, size depicted in this specification institute accompanying drawings etc., only coordinating
Content disclosed in bright book, so that those skilled in the art understands and reads, being not limited to the utility model can implement
Qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size,
In the case where not influenceing the effect of the utility model can be generated and the purpose that can reach, all should still fall disclosed in the utility model
Technology contents obtain and can cover in the range of.Meanwhile in this specification it is cited as " on ", " under ", "left", "right", " in
Between " and " one " etc. term, be merely convenient to understanding for narration, and be not used to limit the enforceable scope of the utility model, its
Relativeness is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1 to Figure 2, a kind of three-phase embedding PFC inductance, including inductance body 1 and shell 2, set in the shell 2
Have and be not less than three size identical accommodating chambers 21, each accommodating chamber 21 it is in the same size, and between two neighboring accommodating chamber 21
Distance be not more than 2cm, the inductance body 1 is in accommodating chamber 21；One end of the inductance body 1 is electrically connected with extraction
Line 3, lead-out wire 3 are connected with external power source, provide operating voltage for inductance work, the lead-out wire 3 extends to outside shell 2；Institute
Stating embedding between inductance body 1 and shell 2 has casting glue；Traditional PFC inductance needs to distinguish coiling 12 on iron core 11,
Technique for coiling is complicated, and assembling is complicated；Or formed for three identical inductance in parallel, so need to reserve around PFC inductance
Enough heat-dissipating spaces, and volume of PFC inductance itself is also bigger, so very big installation dimension is needed, and meanwhile it is also very heavy；And
Three-phase embedding PFC inductance of the present utility model, PFC inductance is directly inserted in accommodating chamber 21, and by embedding that PFC inductance is complete
It is potted in entirely in metal shell 2；Because the radiating of casting glue is good, the distance between accommodating chamber 21 can accomplish it is smaller, and only
It need to install once, save manpower and cost.
In the present embodiment, the inductance body 1 includes iron core 11 and coil 12, and lead-out wire 3 is located at the one of coil 12
Side, facilitate lead；The shape of iron core 11 is in hollow annular, and pad 4, the line are connected between the iron core 11 and coil 12
Circle 12 is respectively arranged on the both sides of iron core 11, and iron core 11 and coil 12 can be separated, avoided between iron core 11 and coil 12 by pad 4
Fitting heating influences each other；The material of iron core 11 uses Fe-based amorphous alloy or iron-base nanometer crystal alloy；Traditional iron core 11 is logical
The metal magnetic powder cores such as Chang Weitie silicon, iron sial, also useful manganese-zinc ferrite do the material of iron core 11, less to use Fe-based amorphous, root
It is different with environment according to frequency of use, different materials can be selected as iron core 11；Wherein the metal magnetic powder core feature such as iron silicon is damage
Consumption is especially big, and identical power volume can be made very big；Very little is lost in manganese-zinc ferrite, but magnetic flux density is especially low, temperature
Stability is very poor, so volume can also be made especially big, and as temperature change performance is widely different.It is Fe-based amorphous loss compared with
Small, magnetic flux density will be big than metal magnetic powder core and manganese-zinc ferrite, and temperature rise stability is preferable, and volume energy is made than the above two
It is small, but a disadvantage is that noise is very big, due to the good thermal diffusivity of casting glue, thermal conductivity and sound-proofing, use it is Fe-based amorphous can be with
Inductance is allowed to keep larger power while the volume of inductance is made very small.
In the present embodiment, the material of the shell 2 uses aluminium alloy, and PFC inductance can be allowed to resist external impact, avoided
The element damaged inside inductance.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this
The spirit and scope of utility model technical scheme.
