Description

Technical Field

[0001] The present invention relates to the technical field of inductance, and in particular to an energy storage inductance coil protection device with high-efficiency heat dissipation. Background Art

[0002] An inductor is an electronic component made of spirally wound wire. Its operating principle is based on Faraday's law of electromagnetic induction. When the current passing through the coil changes, a changing magnetic field is generated around the coil. This changing magnetic field, in turn, induces an induced electromotive force in the coil in the opposite direction of the current change, thereby hindering the change in current and exhibiting the characteristic of inductance. In circuits, inductors primarily store magnetic field energy, blocking the passage of alternating current (AC) while allowing the passage of DC. They are widely used in filter circuits to remove power ripple, in tuned circuits to select specific frequency signals, in transformers to achieve voltage conversion, in chokes to suppress high-frequency interference, and in switching power supplies to store and release energy. They are an indispensable basic component in modern electronic equipment, and their performance directly affects the efficiency and stability of the circuit.

[0003] A Chinese patent document (publication number: CN118231087B) discloses an inductor assembly and an inductor device, comprising an inductor housing, a connector disposed at the bottom of the inductor housing, a wiring harness connector disposed on one side of the inductor housing, a cooling channel disposed at the top of the outer side of the inductor housing, an inductor module disposed at the top of the inductor housing, a cover disposed at the bottom of the inductor module, a first electric push rod disposed within the inductor housing, a support plate fixedly connected to the top of the first electric push rod, a movable groove disposed within the support plate, a second electric push rod disposed within the movable groove, a sliding plate fixedly connected to the bottom of the second electric push rod, fixed blocks disposed at both ends of the sliding plate, and a movable groove disposed in the middle of the fixed block. After the inductor module is installed on the inductor module via the support plate, a buffer block and a telescopic plate are used to cushion the inductor housing from compression and collision, thereby securing the inductor module within the inductor housing, preventing deformation and damage to the inductor module and facilitating use.

[0004] In the existing technology, the heat dissipation and shape correction of the inductor coil need to be implemented separately by independent systems, which leads to the complexity of the equipment and increased energy consumption; the coil out-of-roundness will worsen the heat dissipation effect, and poor heat dissipation will aggravate the deformation, forming a vicious cycle; the existing correction device lacks the ability to automatically identify the roundness state of the coil and cannot make differentiated adjustments according to actual needs, which is prone to ineffective correction or insufficient correction; at the same time, the existing correction system relies on external control signals and sensors to determine the stopping time, and there is a risk of response lag and over-correction, and continuous operation causes unnecessary energy consumption, reducing the overall efficiency and reliability of the system. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a highly efficient heat dissipation energy storage inductor coil protection device. The process of dissipating heat to the inductor coil through a fan can simultaneously adjust the roundness of the coil, avoiding additional correction energy consumption; the improvement of the coil roundness in turn promotes the improvement of the heat dissipation effect, forming a positive feedback loop of "correction promotes heat dissipation, and heat dissipation assists correction"; the device automatically identifies the roundness state of the coil and makes a differentiated response. When the coil is out of round, it automatically combines with the transmission to perform correction, and when the coil restores its roundness, it automatically separates and stops correction; three-dimensional heat dissipation from the inside to the outside is achieved through the axial through-hole of the magnetic core, breaking the technical bottleneck that traditional inductor coils can only rely on the outer surface to dissipate heat, and combined with the spiral blade enhanced heat exchange technology, the heat dissipation efficiency is significantly improved; when the correction is completed, the device automatically triggers the clutch separation through the uniform force on the touch panel, without the need for external control signals or sensor judgment, achieving a completely passive automatic stop, avoiding excessive correction and continuous energy consumption.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the process of dissipating heat from the inductor coil by a fan can simultaneously adjust the roundness of the coil, avoiding additional correction energy consumption; the improvement of the coil roundness in turn promotes the improvement of the heat dissipation effect, forming a positive feedback loop of "correction promotes heat dissipation, and heat dissipation assists correction"; the device automatically identifies the roundness state of the coil and makes a differentiated response. When the coil is out of round, it automatically combines with the transmission to correct it, and automatically separates and stops correction when the coil regains its roundness; three-dimensional heat dissipation from the inside to the outside is achieved through the axial through-hole of the magnetic core, breaking the technical bottleneck that traditional inductor coils can only rely on the outer surface for heat dissipation, and combined with the spiral blade enhanced heat exchange technology, the heat dissipation efficiency is significantly improved; when the correction is completed, the device automatically triggers the clutch separation through the uniform force on the touch panel, without the need for external control signals or sensor judgment, achieving a completely passive automatic stop, avoiding excessive correction and continuous energy consumption.

[0019] 2. In the present invention, when the inductor coil reaches a temperature threshold, the fan is activated to generate moving airflow. The moving airflow not only dissipates heat from the inductor coil, but also accelerates the airflow in the axial through-holes on the magnetic core, thereby cooling both the inside and the outside. The airflow also simultaneously drives the pneumatic blades to rotate and correct the out-of-roundness of the coil.

[0020] Specifically, multiple through holes are opened in the axial direction of the magnetic core, avoiding the limitation of the solid magnetic core structure that heat can only be dissipated through the outer surface. A transmission shaft is passed through the through holes, and spiral blades are set on the periphery of the transmission shaft. The spiral blades can force the airflow to rotate along the cylinder wall, breaking the laminar boundary layer, promoting full contact between the airflow and the cylinder wall, and significantly improving the convective heat transfer coefficient; the spiral blades eliminate the dead zone of the flow, prevent the airflow from being retained in a local area of ​​the cylinder, and promote rapid heat dissipation;

[0021] 3. In the present invention, the process of cooling the inductor coil through the fan can simultaneously adjust the roundness of the coil. The device automatically identifies the roundness of the coil and responds differently. When the coil is out of round, it automatically combines with the transmission to correct it. When the coil regains its roundness, it automatically disengages and stops the correction. When the correction is completed, the device automatically triggers the clutch to disengage by evenly applying force to the touch panel. No external control signal or sensor judgment is required, achieving a completely passive automatic stop, avoiding overcorrection and continuous energy consumption.

[0022] Specifically, when the coil is out of round, the second ring body and the first ring body are firmly combined and rotate synchronously through the clutch assembly; when the coil roundness is normal, the two ring bodies are separated and idle; in the out-of-round state, each touch plate presents a differentiated response, some touch plates are pressed and contacted with the deformed coil, and the remaining touch plates maintain a distance from the coil; when the touch plate is in a state without external force, the first trapezoidal column teeth are embedded and abutted with the second trapezoidal column teeth, the push plate is located inside the slide slot, and the pressing unit is not activated. At this time, the reset ring body has no pressure on the guide rod, and the connecting column extends into the guide groove to connect the second ring body with the first ring body; when the pressure of the touch plate reaches the threshold, the guide rod moves downward to make the small end face of the trapezoidal column teeth abut, driving The outer push plate moves outward, and the outer push plate pushes the contact rod, which moves the first reset ring or the second reset ring downward through the lever principle. The reset ring pushes the guide rod through the inclined transmission pair, pushing the connecting column back into the slide slot to separate the two ring bodies; after the fan is started, the pneumatic blades are driven to rotate, driving the power gear to operate, and the power gear drives the outer gear ring and the second ring body at the same time. When the two ring bodies are combined, the power is transmitted to the inner gear ring, driving the first gear, the transmission shaft and the second gear to rotate, and the gear drives the rack to move radially outward, and the contact plate squeezes the coil to adjust the roundness; when the coil roundness returns to the standard state, all touch plates are evenly stressed, the connecting column returns to the slide slot, the two ring bodies are separated, the outer gear ring idles, and the adjustment is completed.

The end of the magnetic core 11 is fixed with a rotating mechanism, and the rotating mechanism includes a sleeve 18, one end of the sleeve 18 is fixedly mounted on the end of the magnetic core 11, and the other end of the sleeve 18 is fixedly connected to an annular guide sleeve. A first ring body 32 is rotatably provided inside the annular guide sleeve, and one end of the first ring body 32 extends to the outer circumferential surface outside the annular guide sleeve and a second ring body 33 is rotatably provided. A clutch assembly is provided between the two ring bodies, and the two ring bodies away from the annular guide sleeve are in the same direction. A cover plate 17 is provided at the end, and the cover plate 17 is fixedly connected to the outer wall of the annular guide sleeve through a docking ear 19; an inner gear ring 21 is provided on the inner wall of the first ring body 32, and an outer gear ring 20 is provided on the outer wall of the second ring body 33. The outer gear ring 20 is connected to the power assembly, and the inner gear ring 21 meshes with the first gear 22 in the array along the center of the circle. The transmission shaft 58 of the first gear 22 extends through the through hole to the other end of the magnetic core 11. The other end of the transmission shaft 58 is fixed with a second gear. The first gear and the second gear are respectively connected to the adjacent touch plate 13 through a telescopic assembly; when the coil 12 is adjusted for roundness by several touch plates 13, the first ring body 32 and the second ring body 33 automatically disconnect the transmission through the clutch assembly;

[0034] The docking ear 19 includes a first docking ear 30 and a second docking ear 31. The first docking ear 30 is fixedly connected to the cover plate 17, and the second docking ear 31 is fixedly connected to the outer shell 27 of the annular guide sleeve. The first docking ear 30 and the second docking ear 31 are detachably connected by bolts.

[0035] The fan 14 and the coil 12 are both connected to an external power supply and a control system. A temperature sensor is provided inside the inductor coil. When the temperature sensor detects that the temperature reaches a stable threshold, the fan 14 is automatically started through the control system. The fan 14 rotates to generate wind to dissipate heat from the inductor coil and drive the wind blades 15.

[0036] In the present invention, the process of dissipating heat from the inductor coil by a fan can simultaneously adjust the roundness of the coil, avoiding additional correction energy consumption; the improvement in the roundness of the coil in turn promotes the improvement of the heat dissipation effect, forming a positive feedback loop of "correction promotes heat dissipation, and heat dissipation assists correction"; the device automatically identifies the roundness state of the coil and makes a differentiated response. When the coil is out of round, it automatically combines with the transmission to perform correction, and when the coil restores its roundness, it automatically separates and stops correction; three-dimensional heat dissipation from the inside to the outside is achieved through the axial through-hole of the magnetic core, breaking the technical bottleneck that traditional inductor coils can only rely on the outer surface to dissipate heat, and combined with the spiral blade enhanced heat exchange technology, the heat dissipation efficiency is significantly improved; when the correction is completed, the device automatically triggers the clutch separation through the uniform force on the touch panel, without the need for external control signals or sensor judgment, achieving a completely passive automatic stop, avoiding excessive correction and continuous energy consumption.

[0037] In the present invention, when the temperature of the inductor reaches a threshold, the fan is activated to generate a moving airflow. The moving airflow not only dissipates heat from the inductor but also accelerates the airflow in the axial through-holes on the magnetic core 11, thereby cooling both the inside and the outside. The airflow also simultaneously drives the pneumatic blades 15 to rotate and correct the out-of-roundness of the coil.

[0038] Specifically, a plurality of through holes are opened in the axial direction of the magnetic core 11, which avoids the limitation that heat can only be dissipated through the outer surface under the solid magnetic core structure. A transmission shaft 58 is passed through the through hole, and spiral blades are set on the periphery of the transmission shaft 58. The spiral blades can force the airflow to rotate along the cylinder wall, break the laminar boundary layer, promote full contact between the airflow and the cylinder wall, and significantly improve the convective heat transfer coefficient; the spiral blades eliminate the flow dead zone, prevent the airflow from being retained in the local area of ​​the cylinder, and promote rapid heat dissipation.

[0039] Furthermore, the annular guide sleeve includes an inner sleeve 28 and an outer sleeve 27 that are spaced apart from each other. The same end of the inner sleeve 28 and the outer sleeve 27 is fixedly connected to the top plate 29, and the other end of the top plate 29 is fixedly connected to the sleeve 18. An annular space is formed between the two sleeves and has an annular opening. The first ring body 32 is rotatably sleeved in the annular opening of the annular space, and the end of the first ring body 32 rotates to abut against the top plate 29, and the outer sleeve 27 rotates to abut against the end of the second ring body 33.

[0040] Furthermore, an inner ring groove 36 and a second open ring groove 35 are provided at the end of the first ring body 32 away from the sleeve 18. The inner ring groove 36 is located near the inner wall of the first ring body 32, and the second open ring groove 35 is located near the outer wall of the first ring body 32. The second open ring groove 35 extends outward from the center of the circle in the radial direction to the outer peripheral edge of the first ring body 32, forming a first open end on the outer periphery of the end face of the first ring body 32; a first open ring groove 34 is provided on the end of the second ring body 33 away from the sleeve 18, and the first open end is formed on the outer periphery of the end face of the first ring body 32. The annular groove 34 is located near the inner wall of the second ring body 33 and extends to the inner peripheral edge to form a second open end. The first open annular groove 34 and the second open annular groove 35 each have only one sidewall surface. The first open annular groove 34 and the second open annular groove 35 are arranged on the same diameter plane to form a combined annular groove; an inner limiting ring plate 25 and an outer limiting ring plate 24 are fixed to one end of the cover plate 17 near the second ring body 33. The inner limiting ring plate 25 extends into the inner annular groove 36 to abut and rotate, and the outer limiting ring plate 24 extends into the combined annular groove to abut and rotate;

[0041] The outer sleeve 27, the inner sleeve 28, the top plate 29, the inner limiting ring plate 25 and the outer limiting ring plate 24 limit the first ring body 32 and the inner gear ring 21, allowing only rotation;

[0042] The first ring body 32 , the outer outer body 27 and the outer limiting ring plate 24 limit the second ring body 33 and the outer gear ring 20 so that they can only rotate.

[0043] Furthermore, the clutch assembly includes several first slide grooves 41 and second slide grooves 42 opened on the second ring body 33, the openings of the first slide grooves 41 and the second slide grooves 42 are both facing the center direction of the radial plane in which they are located, the first slide grooves 41 and the second slide grooves 42 are spaced apart in the axial direction of the second ring body 33, and the second slide grooves 42 are closer to the first open ring groove 34 than the first slide grooves 41; a first guide groove 45 is opened on the first ring body 32 corresponding to the first slide groove 41, and a second guide groove 46 is opened corresponding to the second slide groove 42; a first return spring 43 and a first connecting column 44 are arranged inside the first slide groove 41, a first tension spring and a first guide rod 47 are arranged inside the first guide groove 45, a second return spring and a second connecting column are arranged inside the second slide groove 42, and a second tension spring and a second guide rod 48 are arranged inside the second guide groove 46; when any group of connecting columns extends into the corresponding guide groove under the action of the return spring, the first ring body 32 and the second ring body 33 are fixedly connected to perform transmission.

[0044] When the fan 14 is started, it drives the pneumatic blades 15 to rotate, which in turn drives the power gear 16 to operate. The power gear 16 drives the outer ring gear 20 and the second ring body 33 simultaneously through meshing transmission. At this time, when the second ring body 33 and the first ring body 32 are coupled through the clutch assembly, power is transmitted to the inner ring gear 21, causing it to start rotating.

[0045] The inner ring gear 21 drives the first gear 22 through meshing transmission, and the first gear 22 in turn drives the transmission shaft 58 and the second gear to rotate synchronously. During this transmission process, the first gear 22 and the second gear respectively drive the corresponding rack to move outward from the radial plane. The contact plate 13 located on the top of the rack 23 applies a squeezing force to the adjacent coil 12, thereby gradually adjusting the roundness of the coil 12.

[0046] As the adjustment process continues, when the roundness of the coil 12 is completely restored to the standard state, all the contact plates 13 reach a balanced state of uniform extrusion; at this time, all the connecting columns in the clutch assembly retreat to the corresponding slide grooves, so that the first ring body 32 and the second ring body 33 are reliably separated, the power transmission is interrupted, and the outer ring gear 20 immediately enters the idling state, and the entire adjustment process is completed.

[0047] In the present invention, when the inductor coil reaches the temperature threshold, the fan is started to generate moving airflow. While the moving airflow dissipates the heat of the inductor coil, it also accelerates the movement of the airflow in the axial through hole on the magnetic core 11, thereby cooling the inside and outside at the same time. The airflow will also synchronously drive the pneumatic blades 15 to rotate to correct the out-of-roundness of the coil; when the coil is out-of-round, the clutch assembly drives the gear ring and the telescopic assembly to work together, so that the touch plate 13 is pushed outward, thereby improving the roundness of the coil, effectively reducing or eliminating the skin effect and proximity effect caused by the irregular geometric shape of the coil, reducing energy loss, and the coil with improved roundness is more conducive to improving the heat dissipation effect, so that the overall electrical performance and thermal performance of the inductor coil are dual optimized.

[0048] Furthermore, the ends of the first guide groove 45 and the second guide groove 46 are both located between the limit ring plate 24 and the inner limit ring plate 25, and a first reset ring groove 37 and a second reset ring groove 39 are respectively provided on the first ring body 32 perpendicular to the two guide grooves, and the reset ring groove is located at one end close to the cover plate 17; the first reset slide 37 is connected to the first guide groove 45, and the first reset ring body 38 is installed in the first reset slide 37, the second reset ring groove 39 is connected to the second guide groove 46, and the second reset ring body 40 is installed in the second reset ring groove 39, and a pressing unit is provided above the first reset ring body 38 and the second reset ring body 40; an inclined surface is provided on the end of the reset ring body located in the reset slide groove, and a corresponding inclined surface is provided on the end of the guide rod adjacent to the reset ring body. When the pressing unit causes the reset ring body to move downward, the guide rod is pushed toward the guide groove and the connecting column is pushed back into the slide groove, so that the first ring body 32 and the second ring body 33 are separated and rotated independently;

[0049] It should be noted that when the guide rod pushes the connecting post back into the chute, the first ring body 32 and the second ring body 33 are disconnected, further disconnecting the transmission connection between the inner gear ring 21 and the outer gear ring 20, thereby achieving idling. The guide rod is always located in the guide groove to ensure the stability of the clutch assembly.

[0050] A limit plate can be set at the opening of the guide groove, which is used to limit the guide rod to avoid excessive sliding; specifically, an installation groove is extended outward from the guide groove, and the limit plate is installed in the installation groove. A limit opening groove is set on the guide rod near the guide groove, and the limit opening groove corresponds to the limit plate. The limit plate prevents the guide rod from excessive movement and ensures that the guide rod can completely push out the connecting column; the ends of the connecting column and the guide rod are both chamfered structures, which are conducive to stable contact and avoidance during movement.

[0051] Furthermore, the telescopic assembly includes a slide 49 with a hollow structure, a rack 23 is fixed on one side of the slide 49, the rack 23 meshes with the first gear 22, the extension line of the moving direction of the slide 49 passes through the center of the ring body, and the slide 49 passes through the cover plate 17, the inner limit ring plate 25 and the outer limit ring plate 24 and is slidably connected; a notch is provided on the side of the slide 49 away from the rack 23, an outer push plate 53 is provided in the notch, and the four corners of the outer push plate 53 are slidably connected to the slide 49 through guide columns, and the guide columns are all equipped with third return springs to make the outer push plate 53 close to the slide 49; the slide 49 slides inward A guide rod 52 is provided on a movable sleeve. One end of the guide rod 52 away from the center of the ring body is fixedly connected to the contact plate 13. A first trapezoidal column tooth is provided on the side of the guide rod 52 close to the outer push plate 53 and is linearly spaced. A second trapezoidal column tooth 56 is provided on the outer push plate 53. The first trapezoidal column tooth and the second trapezoidal column tooth 56 are staggered and inlaid with each other. Two wing plates 50 are fixed on the end of the slide plate 49 away from the center of the ring body. The ends of the wing plates 50 are respectively fixed with guide posts 51. The guide posts 51 are slidably passed through the contact plate 13 and are provided with limit blocks at their ends. A fourth return spring is provided on the guide post between the wing plates 50 and the contact plate 13.

[0052] The cover plate 17, the inner limiting ring plate 25 and the outer limiting ring plate 24 are provided with a limiting groove 26, which provides a sliding channel for the slide plate 49 and plays a limiting role.

[0053] When the slide 49 is driven by the rack 23 to move away from the center of the ring, it drives the contact plate 13 to abut the adjacent coil 12. If the coil 12 is deformed, that is, geometric asymmetry occurs, the shorter pair of contact plates 13 in the diameter of the line connecting the two opposing contact plates through the center of the ring will push the contacting coil outward during movement, restoring the coil to its normal roundness, generating a stable inductance value, reducing skin effect and proximity effect, reducing heat generation, and improving current carrying capacity.

[0054] During the movement of the slide plate 49, the corresponding contact plate 13 will be pushed by the reaction force of the coil 12, driving the guide rod 52 to move toward the center of the ring body, so that the first trapezoidal column teeth and the second trapezoidal column teeth 56 that are dislocated and abutted against each other change their relative positions. The small end faces of the two sets of trapezoidal column teeth form abutment, moving the outer push plate 53 in the direction away from the rack 23. The outer push plate 53 pushes the pressing unit, which transmits the power to the outer limit ring plate 24 and the inner limit ring plate 25, triggering the separation of the connecting column and the first ring body 32 in the separation assembly;

[0055] It should be noted that the skin effect refers to the phenomenon that when alternating current (AC) passes through a conductor, the current density is unevenly distributed on the cross section of the conductor, and the current tends to concentrate near the surface of the conductor, while the current density inside the conductor gradually decreases.

[0056] The array includes components such as the slide 49, the rack 23 and the touch panel 13 installed on the ring body. The number of the array is greater than or equal to 4 groups (i.e., at least 4 touch panels 13) and is an even number, so that the two groups located on opposite sides of the center of the ring body pass through the center of the circle on the connecting line. When pushing toward the outside of both ends, uniform force is ensured; when the number of arrays increases, the ability to adjust the roundness of the coil will be enhanced, and 8 groups are preferred.

[0057] In the present invention, the process of cooling the inductor coil through the fan can simultaneously adjust the roundness of the coil. The device automatically identifies the roundness state of the coil and responds differentially. When the coil is out of round, it automatically combines with the transmission to correct it. When the coil regains its roundness, it automatically separates and stops the correction. When the correction is completed, the device automatically triggers the clutch separation by evenly applying force to the touch panel. No external control signal or sensor judgment is required, achieving a completely passive automatic stop, avoiding overcorrection and continuous energy consumption.

[0058] Specifically, when the coil 12 is out of round, the second ring body 33 and the first ring body 32 are firmly connected by the clutch assembly, and the two rotate together; when the roundness of the coil 12 is in a normal state, the second ring body 33 and the first ring body 32 are separated by the clutch assembly and rotate idly;

[0059] When the coil 12 is out of round, each contact plate 13 will present different states: some contact plates 13 will be in contact with the deformed coil 12, while other contact plates 13 will maintain a certain distance from the coil 12.

[0060] In a normal state where the touch plate 13 is not subjected to external force, the first trapezoidal column teeth and the second trapezoidal column teeth 56 maintain a stable embedded abutment fit, and the outward push plate 53 is inside the notch of the slide plate 49. At this time, the outward push plate 53 does not activate the corresponding pressing unit; in this state, the corresponding reset ring body does not apply a pressing force to the guide rod in the guide groove, so that the corresponding connecting column can smoothly extend into the guide groove, thereby achieving a firm connection between the second ring body 33 and the first ring body 32;

[0061] When the pressure exerted on the touch plate 13 reaches a preset threshold, the system starts to activate the separation mechanism, and the guide rod 52 moves downward, causing the first trapezoidal column tooth and the relatively small end face of the second trapezoidal column tooth 56 to form a tight contact. This action drives the outer push plate 53 to move outward; then, the outer push plate 53 pushes the touch rod 57 in the downward pressure unit, and through the precise lever transmission principle, the first reset ring body 38 or the second reset ring body 40 produces a downward movement; the reset ring body uses the action of the inclined plane transmission pair to vertically push the corresponding guide rod, and the guide rod then pushes the connecting column back to the inside of the slide groove, finally realizing the effective separation between the second ring body 33 and the first ring body 32.

[0062] Furthermore, the pressing unit includes a rotating shaft 54, on which a rotating plate 55 is vertically fixed, and a contact rod 57 is provided at each end of the rotating plate 55. The two ends of the rotating shaft 54 ​​are mounted between the inner limit ring plate 25 and the outer limit ring plate 24 via bearings. A torsion spring is provided on the rotating shaft 54, so that the first contact rod at one end of the rotating plate 55 abuts the outer push plate 53, and the second contact rod at the other end abuts the reset ring body. The second contact rods in adjacent pressing units alternately abut on the first reset ring body 38 and the second reset ring groove 39.

[0063] The first reset ring 38 presses down to drive the first guide rod 47 to push the first connecting post 44, and the second reset ring groove 39 presses down to drive the second guide rod 48 to push the second connecting post. When all the connecting posts are separated from the first ring 32, the first ring 32 and the second ring 33 will rotate relative to each other. Otherwise, the first ring 32 and the second ring 33 remain connected and rotate together.

[0064] That is, during the rotation adjustment of the gear ring, when the coils contacted by all the contact plates 13 are of equal size, the first ring body 32 and the second ring body 33 rotate idly.

[0065] Furthermore, a second cylinder is fixed on the end of the magnetic core 11 away from the rotating mechanism, and several second slides are arranged in the second cylinder along the center array, and the second slides correspond to the slide 49 and slide synchronously, and the second slides all slide through the second cylinder, and the extension line of the moving direction of the second slide passes through the center of the radial plane of the second cylinder, and a second rack is fixed on the second slide, and the second racks are respectively engaged with the second gear; the second slide is a hollow structure, and the second slide slide slides through the second guide rod along the length direction, and the end of the second guide rod is fixedly connected to the contact plate 13; two second wing plates are fixed on the end of the second slide close to the touch plate 13, and the ends of the second wing plates are respectively fixed with second guide posts, and the second guide posts are slidably passed through the touch plate 13 and a second limit block is provided at the end, and a fifth return spring is sleeved on the second guide post located between the second wing plate and the touch plate 13; the transmission shaft 58 is rotatably mounted on the cylinders at both ends of the magnetic core through the connecting seat, and there is a certain distance between the transmission shaft 58 and the inner wall of the magnetic core through hole, and a spiral blade is installed on the outer wall of the transmission shaft;

[0066] It should be noted that, depending on the usage, guide limit sleeves can be fixed inside the cylinder at both ends of the magnetic core. The guide limit sleeves are used to stabilize the movement of the slide and extend the sliding path. The guide limit sleeves are fixedly connected to the cylinder. Two convex rings are respectively extended outward along the axial direction at both ends of the magnetic core 11, and the sleeves at both ends are respectively fixedly sleeved on the outer circumference of the convex rings.

[0067] The spiral blades can force the airflow to rotate along the cylinder wall, breaking the laminar boundary layer, promoting full contact between the airflow and the cylinder wall, and significantly improving the convective heat transfer coefficient; the spiral blades eliminate the flow dead zone, prevent the airflow from stagnating in local areas of the cylinder (avoiding "temperature dead corners"), and promote rapid heat dissipation.

[0068] Two sets of rotating mechanisms can also be symmetrically arranged at both ends of the magnetic core 11, and by setting up multiple sets of pneumatic blades 15, the pneumatic blades 15 receive wind force and convert it into rotational power. The pneumatic blades 15 at both ends can adjust the direction of the spiral so that the pneumatic blades 15 at both ends turn in the same direction, and one-way bearings are provided on the power gears 16 connected to the pneumatic blades 15, and the power of the running pneumatic blades 15 is transmitted to the outer gear ring 20 to avoid reverse obstruction.

[0069] Furthermore, the power assembly includes several power gears 16, which are respectively engaged with the outer gear ring 20. A gear shaft is provided on the power gear 16, and the gear shaft is rotatably installed through a fixed seat. One end of the gear shaft extends toward the fan 14 and a wind blade 15 is installed at the end; a one-way bearing is provided between the power gear 16 and the gear shaft, which only allows the power gear 16 to transmit to the outer gear ring and idle in the reverse direction.

[0070] Furthermore, notches are respectively opened on the side walls of the slide 49 and the second slide, ratchets are respectively provided on the guide rod 52 and the second guide rod corresponding to the notches, and ratchet rods are provided on the outer walls of the slide 49 and the second slide corresponding to the ratchet teeth. The ratchet rods are rotatably connected through a pin shaft, and the pin shaft is installed on the slide through a pin shaft seat. One end of the ratchet rod is connected by a tension spring, and the ratchet rod allows the guide rod to move away from the center of the ring body to prevent reverse movement; a reset component is also provided on the ratchet rod, which can be manually adjusted according to actual usage.

In other words, it does not mean that the present invention must rely on the above-mentioned embodiments to be implemented.
