Embodiment
The embodiment of inductor arrangement of the present invention is described below with reference to the accompanying drawings.Those of ordinary skill in the art can recognize, when without departing from the spirit and scope of the present invention, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection range of claim.In addition, in this manual, accompanying drawing draws not in scale, and identical Reference numeral represents same or analogous part.
In the prior art, because the inside only at inductance coil 2 ' exists sensor magnet, on this inductor, then just there is the existence of induced electromotive force, and due to according to the law of electromagnetic induction, Lenz's law and vortex principle, just a large amount of magnetic lines of force (as shown in Figure 1) is created around the inductance coil 2 ' of energising, that is at the inside and outside magnetic line of force that can produce same quantity of inductance coil 2 ', and prior art just make use of the inner magnetic field of inductance coil 2 ', relative to inefficiency of the present invention, namely the system Joule heat of prior art is:
P＝0.24I
f 2Rt＝0.24·〔(4.44fNФ

Fig. 3 is the sectional view representing inductor arrangement of the present invention.Fig. 4 is the vertical view representing inductor arrangement of the present invention.Fig. 5 is the upward view representing inductor arrangement of the present invention.
As shown in Figure 3-Figure 5, inductor arrangement is made up of the first magnet 1, inductance coil 2, second magnet 3.Inductance coil 2 is wrapped on the first magnet 1, and the second magnet 3 surrounds inductance coil 2.After inductance coil 2 is energized, by inductance principle, alternating magnetic field is produced around inductance coil 2, this magnetic field just produces the closed vortex flow of induction on the wall of the first magnet 1, then the closed vortex flow of this induction carries out the power conversion of electricity-magnetic-Re on the wall of the first magnet 1, thus the electric energy produced after being energized by inductance coil 2 on the first magnet 1 is converted to heat energy; Simultaneously, because the second magnet 3 is also be arranged in the magnetic field range of inductance coil 2, so, on the wall of the second magnet 3, also produce the closed vortex flow of induction simultaneously, and carry out the power conversion of electricity-magnetic-Re, and then the electric energy produced after being also energized by inductance coil 2 on the second magnet 3 is converted to heat energy simultaneously.
Namely, there are two magnets 1 and 3 around same inductance coil 2 simultaneously, that is when same inductance coil 2 is by same electric current, carry out the power conversion of dual electricity-magnetic-Re, thus the electric energy conversion of the overwhelming majority that inductance coil 2 produces by this inductor arrangement is heat energy, thus compared with only there is in Fig. 1-Fig. 2 the situation of magnet 1 ', have and can put forward high-power effect when electric current is constant, and then realize energy-conservation.As mentioned above, the present invention on the basis of existing technology, adds second sensor magnet in the outside of inductance coil 2 ', i.e. the second magnet 3 (shown in Fig. 3), and the present invention compared with prior art, has following development innovation.
First, from the utilance in magnetic field, the conversion of electricity-magnetic-Re has just been done in the magnetic field of the inside of inductance coil 2 by it in the prior art, and the Joule heat power of its conversion is (when not considering loss):
P=P
in=0.24I
f 2rt
And the present invention is the conversion magnetic field in the inside and outside portion of inductance coil 2 all having been carried out electricity-magnetic-Re, the Joule heat power of its conversion is (equally when not considering loss):
P=P
outward+ P
in=0.24I
f 2rt+0.24I
f 2rt=2 (I
f 2rt)
From the power conversion of above electricity-magnetic-Re, the present invention make use of the energy in the magnetic field that inductance coil 2 produces completely, fully, and this is the revolution of primary energy conversion, is also a rapid development of the magnetic energy conversion in an electromagnetic induction field.
Secondly, we are again from angle prior art and the difference place of the present invention more once of magnetic flux, we know, All Media itself all there is certain resistance and magnetic permeability, as everyone knows, its electric current passed through of conductor that resistance is large is just little, its power consumed is relatively just little, its magnetic line of force passed through of the conductor that so magnetic permeability is large is just many, magnetic field is just strong, magnetic flux is larger, and little its magnetic line of force passed through of conductor of magnetic permeability is just few, magnetic field is just weak, magnetic flux is less, magnetic permeability according to the known air of the permeameter of conductor is approximately 1, and the magnetic permeability of ferrimagnet will not be far longer than the hundreds of of air permeability or several ten thousand times not etc., again because the outside of inductance coil 2 ' in the prior art only has air to be 1 as its magnetic permeability of magnetic conductive media, and the present invention is ferrimagnet outside 2 of inductance coil, its magnetic permeability is far away higher than the magnetic permeability of air, therefore the efficiency of electromagnetic induction of the present invention will be far longer than the efficiency of prior art.
Further, we know, in electromagnetic coupling theory, the size of magnetic field intensity, except with the size of the shape of electrical conductor, electric current except, also relevant with the material in magnetic field, relative position.Such as, in the solenoid of same energising, put into different materials (as copper, iron etc.), the magnetic flux density so obtained in same point is not identical, therefore the relative position adjusting inductance coil 2 and the first magnet 1 and the second magnet 3 is also relatively improve one of indispensable condition of of electromagnetic induction heating system efficiency, so the present invention is by upper bracket 6, lower carriage 20, upper adjustment ring 5, lower adjustment ring 19, and fixed adjustment screw 7a, 7d, 8a, 8d, 9a, 9d, 21, 22, 24 grades are to inductance coil 2 and the first magnet 1, second magnet 3 carries out the adjustment of relative position, to make at the first magnet 1, second magnet 3 obtains maximum electromagnetic induction electromotive force, the i.e. maximal efficiency of Electromagnetic Heating.
Further, inductor arrangement also can comprise: for carrying the skeleton 4 of the second magnet 3; Control system 10, pressure detecting 11, water level detecting 12, interior temperature detector survey 13, temperature element 16 are for controlling this inductor arrangement; Exhaust port 14,15; Temperature element 16; External tapping 17; Inner joint 18; Outlet 26; Sewage draining exit 27; Entrance 28; Sewage draining exit 29; Outlet connector 30; Inlet connecting 31; Pump 32.
First magnet 1 and the second magnet 3 can be any geometry, as cylinder, spheroid, Fang Ti, cone and their assembly etc.Fig. 3-Fig. 5 is cylindrical for the first magnet 1 and the second magnet 3, and is not limited thereto.
Magnet 1 can be hollow, also can be solid.
Fig. 3 represents for inductor arrangement to be solid.In figure 3, (namely the radius of magnet a) can be identical, also can be different for the thickness of the thickness of the second magnet 3 and the first magnet 1.Preferably, when the thickness of the second magnet 3 is identical with the thickness of the first magnet 1, be the most effective of heat energy by electric energy conversion.
In order to make inductor arrangement firm, fixture can be adopted the first magnet 1, second magnet 3 and coil 2 to be fixed together.Fixture can comprise adjustment fixture on end face and bottom surface and multiple fixed screw respectively, by the adjustment corresponding to inductance coil 2, adjustment fixture is positioned on the first magnet 1, inductance coil 2 and the second magnet 3 respectively by multiple fixed screw.For Fig. 3-Fig. 5, inductor arrangement of the present invention can comprise upper bracket 6 on end face, lower carriage 20 is comprised in bottom surface, adjustment fixture is such as the upper adjustment ring 5 on upper bracket 6 and the lower adjustment ring 19 on lower carriage 20, upper adjustment ring 5 is fixed on magnet 1,3 and coil 2 respectively by multiple fixed screw 7a, 7d, 8a, 8d, 9a, 9d, and lower adjustment ring 19 is fixed on magnet 1,3 and coil 2 respectively by multiple fixed screw 21-22,24.
Furthermore, if the second magnet increased outside induction coil is too small with the distance of induction coil, then magnetic flux is too concentrated, magnet induction area will be caused to reduce, cause transfer ratio low, and to make it apart from excessive, magnetic flux then can be caused too to disperse, transfer ratio equally also can be caused low, so, this position is arranged on how many positions on earth actually, it just can be made to play maximum transfer ratio? we prove many times for many years by going through and test, summed up at last one ideal, most effective, at two magnets and induction coil, the canoe of inductance coil, and while the parameters index meeting electromagnetic induction power supply, and make cooperatively interacting of the parameter between them simultaneously, both ensure that the coverage of the first magnet and the second magnet and inductance coil simultaneously, make again it on transfer ratio, obtain maximized transfer ratio, namely under must meeting the prerequisite of the above indices described at the same time, the distance the most effective obtained just now, it is made to obtain the maximization of efficiency conversion.
Why to emphasize the first magnet simply, the distance of the second magnet and inductance coil? in fact so-calledly emphasize the first magnet, the distance of the second magnet and inductance coil, be exactly the maximization in order to obtain conversion efficiency in fact, above-mentioned distance is so only had to be only the maximized unique conditional of conversion efficiency, be not in fact, the indispensability that it just satisfies condition and it relatively easily obtains the unique channel of maximal efficiency by adjustment, and this approach that can uniquely regulate is when other conditions known, generate, there is no other known conditions, then this unique adjusting condition has not existed yet.But a desirable conversion efficiency will be expected, then must meet following five indispensable conditions simultaneously:
Namely satisfy condition 1, electric current is constant
2, inductance parameters, the capacitance parameter of induction coil power supply
3, the form of coil and parameter
4, efficiency transfer ratio is maximum
5, the distance of first and second magnet and coil
But, simple calculate according to some single theorem or law after the second magnet is arranged on the outside of inductance coil, the efficiency that its result does not only have, also can cause the reduction of efficiency.
But these conditions are implicative of each other again, mutual restriction, as long as there is a condition to change, so other condition is also along with changing, that is when a condition is met, other condition just has the change deviating from the condition that it meets, and has gradually to the trend that the direction of prerequisite of departure changes, and so just can not obtain the maximization of conversion efficiency.Gone through by us and prove many times for many years and test, finally drawn unique unique solution that simultaneously can meet above condition, namely the coiling of described inductance coil meets following condition simultaneously:
and
wherein, a is the radius of the first magnet 1, and b is the radius of inductance coil 2, and c is the radius of the second magnet 3 inwall, and d is the diameter of inductance coil 2 wire.Only have when this condition must be met, just can obtain the maximization of conversion efficiency.
Wherein, preferably, the scope of the distance of the first magnet 1 and inductance coil 2 is between 15-30 millimeter, and the scope of the distance of the second magnet 3 and described inductance coil 2 is between 3-25 millimeter.Make while the necessary electric capacity of guarantee AC power, the maximum polymerization that have accumulated alternate magnetic force line, makes the exchange efficiency of electricity-magnetic-Re maximum.
Wherein, preferably, the coiling of described inductance coil meets following condition simultaneously:
and
e is the distance in inductance coil 2 between two circle adjacent windings.
Further, when the distance of the first magnet 1 and inductance coil 2 is 20 millimeters, when the second magnet 3 is 25 millimeters with the distance of inductance coil 2, the exchange efficiency of its electricity-magnetic-Re is best.
The manufacture method of inductor arrangement comprises: be wrapped in by inductance coil 2 on first magnet 1; And the second magnet 3 is surrounded inductance coil 2.Specifically, first inductance coil 2 and skeleton 4 are enclosed within the outside of the first magnet 1, then the second magnet 3 is enclosed within outside inductance coil 2, then by upper adjustment ring 5 by upper adjustment ring adjustment screw 8a, 8d installs, be fixed between the first magnet 1 and the second magnet 3, and the carry out adjustment corresponding to inductance coil 2 makes it reach optimum position, more lower adjustment ring 19 is installed by 4 adjustment screws such as 24, be fixed between the first magnet 1 and the second magnet 3, and the carry out adjustment corresponding to inductance coil 2 makes it reach optimum position, and then by upper bracket 6 by external-adjuster screw or interior adjustment screw 7a, 7d, 9a, 9d is fixed on corresponding position, then by lower carriage 20 by external-adjuster screw or interior adjustment screw 21, 22 are fixed on corresponding position, then respectively by upper adjustment ring 5, lower adjustment ring 19 and upper, lower adjusting pole 6, 20 relatively fixing after, then by upper adjustment ring 5, lower adjustment ring 19 pairs of inductance coils 2 carry out relative first magnet 1 and carry out relative adjustment with the position of the second magnet 3 and fix, and make it reach the maximization assembling magnetic flux, by adjustment, lower carriage 6, 20 is also fixing, makes it on the first magnet 1 and the second magnet 3, obtain maximum induced electromotive force.
