Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment one:
As Figure 1-3, equal magnetic circuit described in the utility model full powder core high frequency solid reactor, a kind of equal magnetic circuit full powder core is high
The three-dimensional reactor of frequency, including magnetic core and coil 3, magnetic core includes the core in triangular arranged of three identical cylinder compositions
1, two identical rounded triangle of post or the magnetic cake 2 being positioned at stem stem about 1 both sides of circular composition, stem stem 1 and magnetic cake 2 by
Powder core class material is made, and coil 3 uses lenticular wire to be around in three stem stems 1.The length of magnetic path of three stem stems 1 is identical；Magnetic circuit includes
Stem stem 1 and magnetic cake 2；Powder core class material is iron powder, ferrum silica flour, ferrum aluminum silicon powder, ferrum nikel powder, non-crystalline flour, nanometer crystal powder, powder
The air gap of core class material is uniformly distributed；The both sides up and down of magnetic cake 2 are provided with folder 5 and yoke sheet 4, stem stem 1 by folder 5 with
Magnetic cake 2 contacts；Yoke sheet 4, magnetic cake 2, the through hole being provided centrally with running through up and down of folder 5, fixing device is solid by through hole
Surely lower magnetic cake 2 is lived in；Fixing device uses bolt 7, nut 8 and flat shim 6, bolt 7 pass sequentially through upside yoke sheet 4,
Magnetic cake 2, the folder 5 of upside, the folder 5 of downside, the magnetic cake 2 of downside, the yoke sheet 4 of downside, flat shim 6 and the spiral shell of upside
Female 8 are connected.
Embodiment two:
One of emphasis of the present utility model is: thoroughly solve full powder core class material because of three-phase imbalance, it is impossible to design three-phase
The problem of reactor.What prior art used is all the structure of a kind of plane, and B phase is between A phase and C phase, because A
Longer than B phase with the C phase length of magnetic path mutually, so three pole reactor can be caused uneven, this is the most to be solved in the utility model
One of sixty-four dollar question, it is simply that the imbalance problem between phase place.Plane can only be arranged at owing to prior art also exists three-phase
Technology prejudice, result in this area technology development stagnate always.This utility model by designing three-dimensional magnetic core,
By being magnetic cake 2 up and down, centre is into the shape that equilateral triangle is arranged.Why use said structure, be to examine based on following
Consider.Balance between three-phase to be realized, must realize position consistency and inside and outside difference can not occur between three-phase.And three
Denier wants consistent, namely the same, can only use stereoeffect.And have employed stereochemical structure, it is not connect each other
Lead to, the connection of three-phase can only be realized by a kind of structure.So problem is come, and uses what structure to realize the connection of three-phase？
This utility model have employed full powder core class material structure in view of three-phase, then attachment means is preferably also adopted by said structure, only
So it is only the implementation that this utility model is optimal.But this utility model is merely illustrative magnetic cake 2 and uses the full powder core class material to be
Preferred forms, is not meant to that the connection of the stem stem 1 of three-phase must use full powder core class material, as long as core can be realized
The connection of post 1, is all this utility model content to be protected.This utility model have employed the magnetic cake 2 of rounded triangle or circle
Concept, above-mentioned stem stem 1 is attached.After above-mentioned connection, it is achieved that beyond thought good effect, that is,
The three-phase equilibrium degree of magnetic circuit unexpectedly more collects neutralization than traditional triphase parameter and stablizes, and advantage is clearly.By contrast originally
Three-phase equilibrium degree curve table between the three-phase setting of utility model and plane of the prior art, the full powder core that the present embodiment uses
The stereochemical structure that the stem stem 1 of class material and magnetic cake 2 are constituted is to solve the best of breed of three-phase equilibrium problem at present.As long as use
The implementation solving three-phase equilibrium problem that above-mentioned principle is made, should be all protection category of the present utility model.
Embodiment three:
The two of emphasis of the present utility model are: if solving the heat dissipation problem of radio-frequency rector.In order to solve the problems referred to above, this
The technical staff in field often considers the angle from heat radiation, realizes the cooling of reactor by the way of improving area of dissipation.This reality
With novel, it it is the heat dissipation problem further improving powder core reactor.First, stereochemical structure angle connects than traditional planar structure
The spatial area contacted is big, it is assumed that create identical loss, then the space of heat radiation is the biggest, then the speed of heat radiation is the fastest,
Effect is the most obvious.Secondly, this utility model comes in coil 3 and magnetic core in view of the generation source of loss.Therefore, this is namely
Why this utility model uses lenticular wire as the reason of one of the shape of coil 3.It is known that lenticular wire is relative to traditional circle
Line, its area of dissipation is bigger and less relative to high frequency electric kelvin effect, during energy flows through lenticular wire, energy
Lose the least, cause dispelling the heat also few.Therefore, the utility model proposes the mode solving heat dissipation problem, by test, this
The heat radiation of utility model reduces 3k-5k relative to traditional method temperature rise.Above-mentioned principle is used to improve the enforcement of reactor heat dissipation problem
Mode, all should belong to protection domain of the present utility model, repeat the most one by one.
Embodiment four:
The splicing of stem stem 1 and magnetic cake 2 uses connection member.Relatively common, connection member include flat shim 6, folder 5,
Folder 5, yoke sheet 4, nut 8 and bolt 7.First, by flat shim 6, yoke sheet 4, folder between the magnetic cake 2 of about two
Part 5, nut 8, bolt 7 are attached and fix.Due to before a splice, magnetic cake 2 is reserved and has connected to bolt 7
Through hole, it is possible to utilize through hole to make upper and lower two magnetic cakes 2 be connected in one by nut 8, bolt 7.And folder from top to bottom 5
The fixing of stem stem 1 can be realized, make magnetic cake 2 closely coupled with stem stem 1, it is achieved that stem stem 1 is securely fastened to two magnetic cakes 2
Inside the solid space formed.
Embodiment five:
Provide relevant parameter of the present utility model below in conjunction with actual product, further illustrate advantage of the present utility model.
As it is shown on figure 3,25A1.55mH (switching frequency 16kHz) three-phase full powder core reactor is row, randomly draws 28pcs and produce
Product are as sample, and A/B/C three-phase equilibrium is write music line chart.Product parameters: first-harmonic f:50Hz, impedance voltage U=12.17V ± 10%
(impedance voltage U=2* π * f*I*L), three-phase equilibrium degree≤5%.From fig. 4, it can be seen that A/B/C tri-phase deviation is the least, deviation
Maximum magnitude within 2.5%, < < 10%.Because using powder core, high-frequency circuit is had the more preferable suitability, can be by
Conventional reactor volume reduces 20%-30%.In view of the ultra-low loss of powder core material, the overall losses of product compares silicon steel reactance
Device can reduce by more than 50%.The air gap of powder core material powder core class material is uniformly distributed, and drastically reduce the area the leakage field that GAP goes out,
Compare tradition silicon steel class reactor noise and reduce the ANSYS magnetic field simulation that 5dB-10dB, Fig. 5 are stem stem 1 triangular arranged
Figure.
Certainly, foregoing is only preferred embodiment of the present utility model, it is impossible to be considered for limiting reality of the present utility model
Execute example scope.This utility model is also not limited to the example above, and those skilled in the art are of the present utility model
Impartial change and the improvement etc. made in essential scope, all should belong in patent covering scope of the present utility model.
