Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
Embodiment one:
As Figure 1-3, equal magnetic circuit of the present invention full powder core high frequency solid reactor, a kind of equal magnetic circuit full powder core high frequency stands
Body reactor, including magnetic core and coil 3, magnetic core include three identical cylinders composition the stem stem 1 in triangular arranged,
Two identical rounded triangle or the magnetic cake 2 being positioned at stem stem about 1 both sides of circular composition, stem stem 1 and magnetic cake 2 are 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
With magnetic cake 2；Powder core class material is iron powder, iron silica flour, iron aluminum silicon powder, iron nickel powder, non-crystalline flour, nanometer crystal powder, powder core class material
The air gap of material is uniformly distributed；The both sides up and down of magnetic cake 2 are provided with folder 5 and yoke sheet 4, and stem stem 1 is by folder 5 and magnetic cake 2
Contact；Yoke sheet 4, magnetic cake 2, the through hole being provided centrally with running through up and down of folder 5, fixing device is fixed by through hole
Lower magnetic cake 2；Fixing device uses bolt 7, nut 8 and flat shim 6, and bolt 7 passes sequentially through the yoke sheet 4 of upside, upside
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 nut 8 phase
Even.
Embodiment two:
One of emphasis of the present invention is: thoroughly solve full powder core class material because of three-phase imbalance, it is impossible to design three-phase reactor
The problem of device.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 phase and C
The phase length of magnetic path is longer than B phase, so three pole reactor can be caused uneven, what this namely the invention solves the problems that most important asks
One of topic, it is simply that the imbalance problem between phase place.The technology prejudice of plane can only be arranged at owing to prior art also exists three-phase,
The technology development that result in this area stagnates always.The present invention is 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 based on considered below.Between three-phase to be realized
Balance, position consistency must be realized between three-phase inside and outside difference can not occur.And three once wants consistent, namely one
Mould is the same, can only use stereoeffect.And have employed stereochemical structure, and it is disconnected each other, can only be by one
Structure realizes the connection of three-phase.So problem is come, and uses what structure to realize the connection of three-phase？The present invention considers three-phase
Have employed full powder core class material structure, then attachment means is preferably also adopted by said structure, is only in this way only the present invention optimal
Implementation.But the present invention is merely illustrative magnetic cake 2 uses full powder core class material to be preferred forms, is not meant to three-phase
The connection of stem stem 1 must use full powder core class material, as long as the connection of stem stem 1 can be realized, be all that the present invention to protect
Content.Present invention employs the concept of the magnetic cake 2 of rounded triangle or circle, above-mentioned stem stem 1 is attached.Pass through
After above-mentioned connection, it is achieved that beyond thought good effect, that is, the three-phase equilibrium degree of magnetic circuit is unexpectedly than traditional triphase parameter
More collection neutralizes stable, and advantage is clearly.Between being arranged by the three-phase of the contrast present invention and plane of the prior art
Three-phase equilibrium degree curve table, the stem stem 1 of full powder core class material that the present embodiment uses and the stereochemical structure that magnetic cake 2 is constituted are mesh
The best of breed of front solution three-phase equilibrium problem.As long as have employed the realization side solving three-phase equilibrium problem that above-mentioned principle is made
Formula, should be all the protection category of the present invention.
Embodiment three:
The two of the emphasis of the present invention are: if solving the heat dissipation problem of radio-frequency rector.In order to solve the problems referred to above, this area
Technical staff often consider from heat radiation angle, by the way of improving area of dissipation, realize the cooling of reactor.The present invention is then
It it is the heat dissipation problem further improving powder core reactor.First, the sky that stereochemical structure angle touches than traditional planar structure
Between area 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, and effect is the brightest
Aobvious.Secondly, the present invention comes in coil 3 and magnetic core in view of the generation source of loss.Therefore, this namely the present invention is why
Use lenticular wire as the reason of one of the shape of coil 3.It is known that lenticular wire is relative to traditional round wires, its area of dissipation is more
Greatly, and less relative to high frequency electric kelvin effect, during energy flows through lenticular wire, the loss of energy is the least, causes
Heat radiation is also few.Therefore, the present invention proposes the mode solving heat dissipation problem, and by test, the heat radiation of the present invention is relative to tradition
Method temperature rise reduces 3k-5k.Use above-mentioned principle to improve the embodiment of reactor heat dissipation problem, all should belong to the present invention's
Protection domain, repeats 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 the relevant parameter of the present invention below in conjunction with actual product, further illustrate advantages of the present invention.
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 more preferable applicability, 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 presently preferred embodiments of the present invention, it is impossible to be considered for limiting embodiments of the invention scope.
The present invention is also not limited to the example above, and those skilled in the art are made in the essential scope of the present invention
Impartial change and improvement etc., all should belong in the patent covering scope of the present invention.
