The present invention relates generally to a flexible electrically conductive coil, and more particularly to a flexible electrically conductive coil for electromagnetically inducing a fluid.

The invention also relates to a relevant coil combination, a metal wire structure, a coil assembly and an electromagnetic induction processing device. The invention also provides a method for electromagnetically inducing a fluid.

Background

Problems of insufficient fuel combustion and exhaust emissions are always encountered in the currently commonly used fuel-powered engines (e.g., gasoline engines and diesel engines). Which is a problem that causes energy consumption and environmental pollution to the world.

In the existing widely used technical scheme for solving the problems, the engine is either subjected toImprovement for regulating organic fuel and air (oxygen O) by optimizing and improving mechanism design and electronic fuel injection system of engine²) In an attempt to improve the combustion rate of the fuel; or to reduce the emission of harmful substances in the exhaust emissions of engines by using catalysts of the noble metal (platinum type) type and various filtering techniques.

However, these technologies almost all suffer from bottlenecks, and current emission reduction technologies increase costs and cause a loss of engine power output, resulting in indirect energy waste. The reason for this is that the "incomplete combustion phenomenon of fuel" due to the nature of the fuel itself and factors inherent in the engine cannot be fundamentally solved.

The reason for this "incomplete combustion of fuel" is caused by the interface potential of various substances carried by them in nature. Due to the influence of the earth's magnetic field, various substances on the earth have electric potentials, and the positive and negative electric potentials are determined by the properties of the substances. Meanwhile, the external environment of the substance can promote or weaken the intensity of the electric potential of the substance. Specifically, the method comprises the following steps:

A. organic fuels (gasoline, diesel oil, heavy oil, aviation kerosene, ethanol, industrial alcohol, liquefied petroleum gas, liquefied natural gas, etc.) themselves tend to take on a positive (+) potential at their external interface due to the influence of the earth's magnetic field and the electrostatic influence generated by oxidation and vibration friction during storage. Organic fuels are very easily charged, for example, tank vehicles that transport liquid fuels must be equipped with high-performance electrostatic discharge devices to discharge a large amount of static charge generated by sloshing friction during transportation of the liquid fuel in the tank. If the accumulated static charge cannot be released to the ground in time, the charge discharge can cause 'static fire' to explode the oil tank;

B. meanwhile, the organic fuel is a mixture, and the interface potential strength among various molecules in the fuel is not uniform, so that the molecular groups in the components are different in size. Current fuel electron injection technology is not able to effectively break up fuel clusters, which results in large differences in the size and composition of the fuel particles injected into the engine cylinder;

C. organic fuel can absorb moisture in the air in the process of keeping the fuel in storage, part of water molecules can attract fuel molecules due to the influence of interface potential, and when the oil-gas mixed gas is subjected to deflagration, the moisture can hinder the combination of the fuel molecules and oxygen molecules and can absorb heat at the same time, so that incomplete combustion is caused;

D. air molecules also tend to carry a positive (+) interface potential to the outside due to the influence of various causes (ultraviolet rays, air pollution, electromagnetic fields, etc.). Also, there are many water vapor molecules (air humidity) in the air, and thus air particles drawn into the engine are charged with a positive (+) potential. Water vapor molecules in the air are easy to move towards the inner wall of the combustion chamber or attach to nonpolar fuel molecular groups, so that the explosive combustion efficiency is influenced;

E. since the engine is grounded, that is, connected to the negative electrode of the battery, and the inner surface of the fuel injection oil passage and the inner surface of the cylinder (combustion chamber) are substantially made of metal, the interface potential of the metal is negative (-) potential.

Due to the interaction between the fuel, air, and the interface potential inside the engine, two types of "incomplete combustion" occur when the fuel is combusted inside the engine:

(1) since the fuel fine particles themselves have a positive potential (+), some of them are adsorbed on the inner wall (-) of the combustion chamber to form a fuel film layer similar to the dew condensation state. This fuel film layer is not able to form the "explosive combustion" required for power output due to the endothermic influence of the inner wall of the engine, but forms relatively mild combustion. Since the detonation reaction within the engine is completed in a very short time, this relatively mild combustion is less than a complete combustion reaction, resulting in a relative "incomplete combustion";

(2) since the molecular groups of the fuel particles injected into the engine are not uniform, the large molecular groups take longer to complete the knocking reaction. The larger the molecular mass, the higher the chance of "incomplete combustion" formation.

A method of treating a fluid using electromagnetic induction is disclosed in applicant's patent CN101988448B, which is incorporated herein by reference. The polarity of the interfacial potential of the fuel fluid molecules can be effectively controlled by this treatment: the polarity of the electric potential of the fluid molecules can be eliminated as required, namely, the electric potential neutralization; or an interface potential that negatively (-) charges the fluid molecules or an interface potential that positively (+) charges the fluid molecules.

By this treatment, the following effects can be achieved:

(1) preventing the fuel particles or water molecule particles from adhering to the inner face of the engine combustion chamber: because the interface potential inside the combustion chamber of the engine is negative (-), the fuel particles with negative potential and the water vapor particles are naturally repelled, so that the fuel particles or the water vapor particles are prevented from being attached to the inner wall surface of the combustion chamber, and the fuel particles are completely suspended in the combustion chamber to form mixed gas with air;

(2) large molecular group effect inside the pulverized fuel: the molecular groups within the fuel are repelled from each other by the homo-polarity (-) interface potential between the fuel molecules, thereby effectively pulverizing the fuel molecular groups and preventing the fuel molecules from agglomerating again. The uniform fuel particles facilitate more complete explosive combustion. The improvement of the complete combustion rate of the fuel can also effectively reduce the generation of toxic carbon monoxide (CO) and Hydrocarbon (HC).

(3) Preventing the formation of harmful oxides: the interface potential of the impurities (mainly sulfur, moisture, etc.) in the fuel is also converted into negative (-) property, SO that the sulfur molecules and the fuel molecules are promoted to form repulsive separation, the sulfur molecules in the fuel are prevented from competing for oxygen molecules with the fuel molecules, and the generation of sulfur dioxide (SO2) is prevented. Preventing air pollution. The water molecules contained in the fuel are also provided with negative interface potential to separate the fuel particles from the water molecules and prevent the water molecules from participating in the combustion reaction.

After the treated mixed gas (fuel/air) is compressed, when the mixed gas is ignited, the detonation reaction is more violent under the same environmental condition, the temperature of the detonation is higher, the explosive force generated by the detonation is larger, and the increase of the power output of the engine under the lower revolution number can be realized, so that the effects of saving energy, reducing the emission of carbon dioxide and reducing the emission of harmful substances are realized.

In modern industrial applications, the electromagnetic coil is mainly a solenoid coil wound in a spiral tube manner, and the structure of the electromagnetic coil is shown in fig. 1, and the electromagnetic coil has a three-dimensional structure. When a current flows in the coil conductor, the coil can generate a corresponding dc or ac electromagnetic field, see fig. 2.

When the electromagnetic coil is used for electromagnetic treatment of fluid, the coil spiral pipe is sleeved on the pipeline of the fluid. When it is necessary to perform a specific electromagnetic treatment on a conductive fluid (e.g., water, liquid metal, etc.), a microconductor (e.g., liquid organic fuel, humid air, etc.), or a near-insulating fluid (dry air, etc.), and a current or a potential is generated inside the fluid by using an electromagnetic induction effect, the electromagnetic induction efficiency generated with respect to the fluid by the magnetic field using such a solenoid-type electromagnetic coil is very low. This is because, according to the basic common knowledge of electromagnetic induction (fleming's right-hand law), the current (or potential) in the conductor generated by electromagnetic induction has a close relationship with the moving direction of the conductor and the included angle between the magnetic lines of force, when the conductor makes a magnetic line cutting motion in a magnetic field, an induced potential is generated in the conductor, and the magnitude of the induced potential is proportional to the effective length of the conductor in the magnetic field and the speed of the conductor making a motion in the magnetic field perpendicular to the direction of the magnetic field. When the moving direction of the fluid is perpendicular (at an angle of 90 °) to the direction of the magnetic field lines, the electromagnetic induction efficiency of the electromagnetic field with respect to the fluid is the highest. In contrast, when the flow direction of the fluid is parallel to the magnetic lines (angle 0 °), the electromagnetic field has the lowest electromagnetic induction efficiency for the fluid. When such a solenoid coil of a solenoid type is used, the angle between the flow direction of the fluid and the magnetic lines of force is 0 ° at the place where the density of the magnetic lines of force is the greatest inside the coil, and therefore the electromagnetic induction efficiency is very low (see fig. 3 in which the direction of the fluid flow is indicated by thick arrows).

In some fields using electromagnetic induction technology, in order to obtain the maximum electromagnetic induction effect, a solenoid coil of a spiral pipe type is disposed perpendicular to a fluid pipe, and a magnetic field output portion having the maximum magnetic flux density inside the spiral pipe is perpendicular to a flow direction of a fluid. Electromagnetic flow meters, for example, utilize this principle.

However, the electromagnetic flowmeter requires a solenoid coil perpendicular to the pipe to generate the electromagnetic field, and occupies a large space and height (see fig. 4, in which the solenoid coil 1 is disposed perpendicular to the entire fluid pipe). Also, if a solenoid coil for electromagnetically treating a fluid is provided in a manner similar to an electromagnetic flowmeter, the position through which the fluid flows is not located at a place where the density of magnetic lines of force inside the coil is maximum, and therefore this configuration is also inefficient. Furthermore, the need for a stronger magnetic field leads to a vertically disposed solenoid coil that is bulky and takes up more space, which results in a doubling of construction costs and unstable fixation of the solenoid coil.

Accordingly, there is a need for a more efficient, more convenient to apply technique for electromagnetically inducing a fluid.

Detailed Description

It is to be understood that the following description of the embodiments of the present invention is illustrative only and not restrictive. For example, as used herein, the terms "a," "an," "two," and the like, merely represent the number of elements in a particular embodiment, and are not intended to impose any limitation on its objects, such as a numerical limitation. As another example, the terms "first," "second," and the like, are used merely as labels, and are not intended to impose any limitations on their objects, such as order or hierarchy limitations. As another example, the term "XYZ coordinate system" is merely a coordinate system added for convenience of description, and is not intended to impose any limitation on its objects, such as directional or spatial position limitations. When referring to terms such as "X direction", if not specifically referred to as X positive (X +) or X negative (X-), it is to be understood as broadly including both; the same is true for the "Y direction" or the "Z direction".

Fig. 5 shows a coil according to an embodiment of the invention, in which the coil 10 is shown together with an XYZ coordinate system. The coil 10 comprises several turns of wire, which all lie in the same plane, i.e. the XY plane. In other words, the coil 10 has a significant dimension in the direction X, Y, but no significant dimension in the Z-direction, such that the coil 10 can be viewed as extending only in the XY-plane. In the XY plane, the coil 10 includes four portions. Starting from a position where the Y axis is farther from the origin O, in the counterclockwise direction, there are a first section 11, a second section 12, a third section 13, and a fourth section 14 in this order.

As shown in fig. 5, the coil 10 has a greater span along the Y-axis than along the X-axis. If the direction along the Y-axis is defined as the longitudinal direction and the direction along the X-axis is defined as the transverse direction, then the span along the Y-axis is the length and the span along the X-axis is the width. In this embodiment, the aspect ratio of the coil 10 is greater than 1. It should be understood that the aspect ratio of the coil 10 may be different in different embodiments, and its span along the Y-axis may be less than or equal to its span along the X-axis, if desired.

In fig. 5, the first portion 11 and the third portion 13 extend mainly in the X direction, and they can be considered as two opposite side portions of the coil 10 distributed along the Y axis. While the second portion 12 and the fourth portion 14 extend mainly in the Y-direction and can be considered as two opposite side portions of the coil 10 distributed along the X-axis. In this embodiment, the first and

third portions

11, 13 each have an outwardly convex curvature, while the second and

fourth portions

12, 14 each have an inwardly concave curvature to accommodate the curvature of the first and

third portions

11, 13. That is, the first portion 11 and the third portion 13 have a larger span in the X direction as they extend from the end points of the Y direction to the middle, and the arcs of the second portion 12 and the fourth portion 14 that receive the first portion 11 and the third portion 13 have a smaller span in the X direction as they continue to extend to the middle. Thus, the coil 10 forms two centers of curvature inside. This shape causes the magnetic lines of force of the coil to be more concentrated when energized, thereby enhancing the electromagnetic induction effect. In some preferred embodiments, the minimum span of the coil 10 in the X direction is 1/4 to 1/2 of the maximum span.

It will be appreciated that in other embodiments the form of the projections or recesses of the portions may vary, for example, the second and

fourth portions

12, 14 may be straight or may also have outward projections.

As shown in fig. 5, the coil 10 in this embodiment is shaped like an "8" as a whole. This is because the first and

third portions

11, 13 each have outwardly convex curvatures, while the second and

fourth portions

12, 14 each have inwardly concave curvatures. In other embodiments, the coil 10 can have other shapes, such as circular, elliptical, O-like, and the like.

Referring again to fig. 5, the coil 10 has two

terminals

15, 16. Coil 10 starts at terminal 15 from its outermost periphery and ends at terminal 16 at the innermost periphery. Both

terminals

15,16 may be connected to an external device by wires to connect the coil 10 into a circuit to generate an electrical current. In this embodiment, the

terminals

15,16 are both located on the fourth portion 14 and are located at the center of the fourth portion 14 in the Y-axis direction. It should be understood that in other embodiments, each of the

terminals

15,16 may be disposed at other locations. For example, the terminal 15 may be disposed on the fourth portion 14 and in the middle of the fourth portion 14 in the Y-axis direction, while the terminal 16 may be disposed on the second portion 12 and in the middle of the second portion 12 in the Y-axis direction; alternatively, the

terminals

15,16 are provided on the first portion 11 and the third portion 13, respectively, and are located in the middle of the first portion 11 and the third portion 13, respectively, in the X-axis direction; still alternatively, the terminal 15 is provided on the fourth portion 14 and the terminal 16 is provided on the first portion 11.

Fig. 6 schematically shows the magnetic field generated by the coil 10 of fig. 5 after being energized with electric current. As shown, current flows through coil 10 in a counterclockwise direction from terminal 15. At this time, the coil 10 generates a magnetic field. According to the ampere rule, the lines of force of the generated magnetic field are directed from inside the paper to outside the paper, i.e. to the positive infinite direction of the Z-axis, inside the coil 10, and from outside the paper to inside the paper, i.e. to the negative infinite direction of the Z-axis, outside the coil 10.

The coil 10 is flexible and can be rolled in the direction of the Z-axis into a three-dimensional shape with significant dimensions in all three directions X, Y, Z. The coil 10 is preferably composed of an electrically conductive metal, however, it may also comprise other materials, such as an electrically conductive carbon material.

Referring again to fig. 5, the coil 10 has an axis of symmetry SAY in the Y-axis direction. If the coil 10 is folded about the axis of symmetry SAY, the two sides may be substantially coincident. In this embodiment, the coil 10 also has an axis of symmetry SAX in the X-axis direction. It should be understood that in other embodiments, the coil 10 may have only one axis of symmetry or no axis of symmetry.

When the coil 10 is installed on a pipe through which a fluid flows, the coil 10 may be rolled to conform to the outer shape of the pipe. It is believed that almost all of the fluid conduit is substantially circular in cross-section and that for the coil 10, it is crimped to substantially conform to the shape of a cylinder.

Fig. 7 schematically shows the coil 10 in a coiled shape conforming to a pipe. Referring to fig. 5 and 7 together, the coil 10 is preferably crimped along its axis of symmetry SAY such that the distance between the two ends of the coil 10 that would otherwise be distributed in the Y-axis direction is increasingly closer. When the length of the coil 10 in the Y-axis direction exactly matches the outer circumference of the cross-section of the fluid conduit, the two ends will be brought into exact contact by crimping. Of course, in some embodiments, the two ends may also partially overlap. In a preferred embodiment, the length of the coil is the cross-sectional perimeter or 1/2 cross-sectional perimeter of the conduit through which the fluid flows, and the width of the coil is the cross-sectional diameter of the conduit through which the fluid flows.

In a preferred embodiment, the axial direction of the coiled coil 10 (i.e., the direction in which fluid can flow in the pipe) is parallel to the axis of symmetry SAX, and the axis of symmetry SAY of the coil 10 is always in a plane perpendicular to the X-axis and parallel to the YZ-plane, so as to ensure that the magnetic fields generated by the coil 10 when energized will have a superposition effect in the pipe, thereby enhancing the electromagnetic treatment effect. Of course, in some embodiments, the axis of symmetry SAY of the coil 10 may also be offset after crimping, i.e., not in one plane but rather forming a spiral shape in 3D space; in this case, it is also possible to ensure that the magnetic field generated by the coil 10 when energized forms a superposition effect in the fluid conduit.

As shown in the figure, the direction (indicated by dotted lines) of the magnetic field generated by the coil 10 after being wound on the fluid pipeline and energized (the current direction is shown by arrows) is perpendicular to the direction of the fluid flow, and according to fleming's right-hand rule, the acting force of the magnetic field on the fluid is strongest at this time, and the generated electromagnetic treatment effect is also strongest.

Figures 8a-8c show some variants of the coil 10. The coil 10 may be designed in various sizes as desired, for example, according to the size of the fluid conduit. As previously mentioned, the aspect ratio of the coil 10 may vary, even less than 1 (i.e., the longitudinal and transverse directions are referred to interchangeably). And in addition to this, the curvature of the curved portion of the coil 10 may also be varied.

Fig. 9 and 10 show some expanded forms of the coil 10 in practical use. Fig. 9 shows a coil extension of three coils 10 connected in series in the same plane. Fig. 10 shows a coil extension of two parallel coils 10 in the same plane. It should be understood that the number of coils 10 included in the coil extension may be any, whether in series or parallel. The coil extension may include both a series connection and a parallel connection. Further, the coils 10 may be arranged side by side along the X axis or may be arranged side by side along the Y axis, as viewed from the arrangement of the coils in the XY plane. The advantage of using these extended forms of the coil 10 is that the magnetic field generated by the coil can be easily enhanced, which enhances the electromagnetic treatment effect.

And, although not shown, it will be understood by those skilled in the art that in the expanded form of the coil 10, it is also possible to spatially design several coils 10 in a stacked state, or in a nested state with each other (i.e., the turns of one coil are in the gaps of two adjacent turns of the other coil, and vice versa), or in a hybrid form including at least two of side-by-side, stacked, and nested forms. Of course, in these stacked or nested or mixed forms, the coils 10 are also in a state of being connected in series or in parallel or in both series and parallel in terms of circuit configuration.

Figure 11 shows another form of coil. As shown, the coil 10 ' in fig. 11 includes a first portion 11 ', a second portion 12 ', a third portion 13 ', and a fourth portion 14 ', and also includes two terminals 15 ', 16 '. The first portion 11 'and the third portion 13' extend mainly along the X-axis direction, and the second portion 12 'and the fourth portion 14' extend mainly along the Y-axis direction. The coil 10 ' has an axis of symmetry SAY in the direction of the Y-axis, and the second portion 12 ' and the fourth portion 14 ' are substantially symmetrical about the axis of symmetry SAY. The first portion 11 'has an outwardly convex curvature and the second and fourth portions 12', 14 'receive the curvature of the first portion 11', each with an inwardly concave curvature. The third portion 13 ' has two sub-portions 13 ' -1 and 13 ' -2 which receive the curvature of the second and fourth portions 12 ', 14 ', respectively, and are substantially symmetrical about the axis of symmetry SAY.

The coil 10' in fig. 11, in contrast to the coil 10 in the other schematic drawings (e.g. fig. 8c), only retains the right half in the longitudinal direction. The left half is left out and the turns of the right half are connected by short wires. In practice, this is a "reduced" form of the coil. It will be appreciated that with such a "reduced" form of coil, the fluid may likewise be subjected to electromagnetic treatment; if two coils in the form of the 'reduced' are combined into a 'complete' coil, the effect almost the same as that of the 'complete' coil can be achieved. It should also be understood that in other embodiments, the "reduced" form of the coil may be any portion cut at any location in a "complete" coil.

It should be understood that whatever variant of the coil 10, or whatever "expanded form" or "reduced form" thereof, may be crimped with reference to the method of crimping the coil 10 as shown in fig. 7, provided that the object of the invention is achieved.

Fig. 12 shows a cross-sectional view of a coil assembly 200 according to an embodiment of the invention. The core component of the coil assembly 200 is the coil module 100 located in the middle thereof. The coil module 100 can be the coil 10 mentioned above or its "expanded" or "reduced" form, i.e. a normal coil or a series and/or parallel expansion of a normal coil, or a "part" of a normal coil. The coil module 100 may be covered with a protective layer 103 on both sides or one side thereof. The protective layer 103 is preferably a sponge material and serves to protect the coil module 100 from damage and to insulate heat. If the side of the coil module 100 close to the fluid conduit when installed is defined as the inner side 101 and the side thereof far from the fluid conduit is defined as the outer side 102, then an electromagnetic shielding layer 104 is preferably added to the sponge protection layer 103 on the outer side 102 to enhance the electromagnetic induction effect on the fluid in the conduit. The electromagnetic shielding layer 104 may be made of an aluminum alloy material, or may be made of other materials.

In this embodiment, the coil assembly 200 includes the coil module 100, the sponge protective layer 103 at the inner side 101 and the outer side 102 of the coil module 100, and the electromagnetic shield layer 104 at the outer side of the sponge protective layer 103 at the outer side 102. It should be understood that other layers may be added to the coil assembly 200 to achieve a particular purpose.

Fig. 13 shows, in cross-sectional schematic form, the coil assembly 200 wound around the fluid conduit 105. As shown in the figure, from the outside of the fluid conduit 105 to the outside, there are a sponge protective layer 103 inside the coil module 100, a sponge protective layer 103 outside the coil module 100, and an electromagnetic shielding layer 104 in this order.

Fig. 14 shows a schematic view of an electromagnetically induced treatment device for the treatment of fluids according to an embodiment of the present invention. The two electrodes of the coil assembly 200 are connected to the positive electrode and the negative electrode of the output terminal of a current generator 300 respectively through wires. The current generator 300 applies a current to the coil assembly 200, and the coil assembly 200 generates a magnetic field. When the coil assembly 200 is installed on a pipe through which a fluid flows, the magnetic field generated by the coil assembly 200 generates an electromagnetic induction effect on the fluid. At this time, the magnetic lines of force generated by the coil assembly 200 in the pipeline are perpendicular to the flowing direction of the fluid in the pipeline, so that the effect of the electromagnetic induction treatment on the fluid is substantially maximized.

Here, the applied current may be a direct current or an alternating current. In the case of alternating current, the frequency may be fixed or variable, or may be a mixture of several alternating currents with fixed or variable frequency. In a preferred embodiment, an alternating current is applied in the frequency range 4-25 k.
