The advantages are: by passing voltage through the sharp structure of the above-mentioned metal body, a corona phenomenon will be caused between the grounded metal grounding body under a strong electric field, so that the air near the sharp structure will be ionized, and the same charges on the sharp structure will be repelled, and ions will be emitted to the metal grounding body to make the metal grounding body an ion acceptor, thereby forming electric wind or ion wind, driving the airflow from the metal body to the end of the metal grounding body, and producing a heat dissipation effect.

[0003] In the prior art including the above-mentioned patents, when the ion wind heat dissipation device is in use, the positive and negative electrodes will generate wind force.

[0024] A rotating plate 309 is rotatably provided on one side of the back of the movable plate 302, a torque spring is provided at the axis of the rotating plate 309, a moving plate 308 is rotatably provided on the back of the rotating plate 309, one side of the moving plate 308 penetrates the conical cover 311 and extends to the interior of the conical cover 311, and an ash pushing plate 310 is fixedly provided on one side of the front of the moving plate 308.

[0025] The ion wind generating unit 1 and the ozone removing unit 1b include an insulating frame 10, an emitter 20 and a collector 30. The insulating frame 10 includes a top wall 11, a bottom wall 12 and two opposite side walls 13. The top wall 11, the bottom wall 12 and the two side walls 13 form a receiving space 14. The receiving space 14 has an air inlet 141 and an air outlet 142. The insulating frame 10 also includes a support frame 15. The support frame 15 is located next to the air inlet 141 and its two ends are respectively connected to the two side walls 13. The emitter 20 includes The connecting portion 21 and the conductive brush 22 connected to the connecting portion 21, the conductive brush 22 is composed of densely arranged conductive fibers 23, the connecting portion 21 is arranged on the support frame 15, and the collector 30 includes two conductive rods 31, each conductive rod 31 is located next to the air outlet 142 and the two ends are respectively connected to the two side walls 13; however, it is not used to limit the present invention, for example, the collector 30 can be changed to include only one conductive rod 31, or can be changed to include three or more conductive rods 31.

[0026] The top wall 11 is detachably connected to the two side walls 13; however, it is not intended to limit the present invention. For example, the top wall 11 can be changed to be fixedly connected to the two side walls 13, that is, the insulating frame 10 is an integrally formed part, as long as the insulating frame 10 does not affect the installation of the emitter 20 and the collector 30, the top wall 11 can be provided with a plurality of auxiliary air inlets 111 and 112, and the auxiliary air inlets 111 and 112 are square and long strip air inlets respectively; however, it is not intended to limit the present invention. For example, the auxiliary air inlets 111 and 112 can be changed to air inlets of other shapes such as circles, as long as these auxiliary air inlets 111 and 112 are not too large and there is no risk of leakage. The inner wall surfaces of the two side walls 13 are sequentially formed with a first forward surface 131, an inwardly inclined inclined surface 132 and a second forward surface 133 from the air inlet 141 to the air outlet 142. When viewed from the air inlet 141 to the air outlet 142, the two side walls 13 The first forward surface 131 cooperates with the top wall 11 and the bottom wall 12 to form a large air inlet channel, which can receive more air; then, the inwardly inclined inclined surfaces 132 of the two side walls 13 cooperate with the top wall 11 and the bottom wall 12 to form a tapered air inlet channel, which can produce a pressurization effect on the incoming air, thereby improving the air ionization effect; finally, the second forward surfaces 133 of the two side walls 13 cooperate with the top wall 11 and the bottom wall 12 to form an air outlet channel, which can output ion wind. In addition, the inner wall surface of each side wall 13 can also be vertically formed with a convex surface 134 between the inclined surface 132 and the second forward surface 133. When the emitter 20 is set, it must not exceed the convex surface 134. The convex surfaces 134 of the two side walls 13 can limit the distance between the emitter 20 and the collector 30 to avoid the distance between the two being too small, resulting in frequent discharge and no ion wind. Moreover, the convex surface 134 can also reduce the influence of the arc generated on both sides of the conductive brush 22 of the emitter 20.

[0027] The support frame 15 includes a horizontal support plate 151 and a vertical support plate 152. The two ends of the horizontal support plate 151 are respectively connected to the middle height of the two side walls 13, and the two ends of the vertical support plate 152 are respectively connected to the middle position of the horizontal support plate 151 and the bottom wall 12. Therefore, after the emitter 20 is set on the support frame 15, the emitter 20 is approximately located in the middle position of the insulating frame 10 and is respectively separated from the top wall 11 and the bottom wall 12 of the insulating frame 10 by a distance, which can largely avoid leakage to the outside of the insulating frame 10; moreover, the horizontal support plate 151 is connected to the middle position of the horizontal support plate 151 and the bottom wall 12. The design of the horizontal support plate 151 and the single vertical support plate 152 takes into account the larger air inlet space and the stability of the support frame 15, but it is not intended to limit the present invention. For example, the support frame 15 can be changed to include only the horizontal support plate 151 without the vertical support plate 152, or can be changed to include multiple vertical support plates 152, and the two ends of each of these vertical support plates 152 are respectively connected to the middle position of the horizontal support plate 151 and the bottom wall 12, and each side wall 13 is provided with two connecting holes 16 next to the air outlet 142, and the two ends of each conductive rod 31 are respectively connected to the corresponding two side walls 13 The two connecting holes 16 are not used to limit the present invention. For example, each side wall 13 can be changed to have two clamping grooves beside the air outlet 142. The two ends of each conductive rod 31 slide into the corresponding two clamping grooves and slide to the ends in the grooves to be clamped or limited. The connecting portion 21 of the emitter 20 is a long strip connecting portion 21. The conductive brush 22 is composed of at least hundreds of conductive fibers 23 with a diameter of micrometers arranged densely along the long strip connecting portion 21. After the connecting portion 21 is arranged on the support frame 15, the conductive brush 22 points to the collector 30. The collector 30 includes two conductive rods 31 and at least one auxiliary conductive rod 32 (two auxiliary conductive rods 32 are used in this example). The auxiliary conductive rod 32 is used to connect the two conductive rods 31 so that the two conductive rods 31 are electrically connected; however, it is not used to limit the present invention. For example, the collector 30 can be changed to include only two conductive rods 31 without including two auxiliary conductive rods 32. When in use, the emitter 20 is electrically connected to the positive or negative pole of the DC power supply, and the collector 30 is electrically connected to the ground terminal or a low potential terminal close to 0 volts.

[0028] The material of the insulating frame 10 includes but is not limited to polymers, composite materials, ceramic materials and other high electrical insulation materials. For example, the material of the insulating frame 10 can be polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), alumina ceramics, aluminum nitride ceramics, etc. The material of the connecting portion 21 of the emitter 20 and the conductive fiber 23 of the conductive brush 22 and the conductive rod 31 of the collector 30 includes but is not limited to metals, alloys, conductive polymers, carbon materials and other conductive materials. For example, the material of the connecting portion 21 can be copper foil, aluminum foil, etc. The conductive fiber 23 includes but is not limited to carbon fibers, conductive polymer fibers (such as polyacetylene fibers, polyaniline fibers, polypyrrole fibers, etc.) Fiber, polythiophene fiber), carbon black fiber, conductive metal compound fiber, etc.; the material of the conductive rod 31 can be titanium alloy (such as TC4, TA1, TA2 alloy), nickel-plated plastic, nickel-plated copper, nickel-plated copper alloy, nickel-plated aluminum, nickel-plated aluminum alloy, nickel-plated zinc, nickel-plated zinc alloy, stainless steel, Nak80 steel, etc., wherein nickel-plated plastic refers to electroplating nickel on the plastic surface, nickel-plated copper refers to electroplating nickel on the copper surface, and nickel-plated copper alloy refers to electroplating nickel on the copper alloy surface, and the like. The design of the convex surface 134 of the insulating frame 10 and the connecting hole 16 limits the distance between the emitter 20 and the collector 30. In one embodiment, the distance between the emitter 20 and the collector 30 is 1 To 10 mm, the length of the convex surface 134 formed vertically is 1 to 10 mm, in addition, the length of the connecting portion 21 of the emitter 20 is 2 to 10 mm, the width is 2 to 10 mm, the length of the conductive fiber 23 of the conductive brush 22 is 2 to 10 mm, the diameter of the conductive rod 31 of the collector 30 is 0.5 to 5 mm, the two conductive rods 31 of the collector 30 are parallel and arranged in an upper and lower distribution, and the conductive brush 22 of the emitter 20 directly points to the middle of the line connecting the two centers of the two conductive rods 31, but it is not used to limit the present invention. For example, the collector 30 can be changed to include only one conductive rod 31, and the conductive brush 22 of the emitter 20 can be vertically pointed to the conductive rod 31, but it can also point to the conductive rod 31 of the collecting electrode 30 at a specific angle. The collecting electrode 30 of the ion wind generating unit 1 and the ozone removing unit 1b only includes one conductive rod 31. In addition, the connecting portion 21 of the ion wind generating / ozone removing unit 1 is designed to be bent and extended in a small section facing the collecting electrode 30. Since the conductive fibers 23 of the conductive brush 22 have a micron-level diameter and are easily bent by external forces, this small bent section of the connecting portion 21 will force the conductive fibers 23 of the conductive brush 22 to bend, so that the conductive brush 22 points to the conductive rod 31 of the collecting electrode 30 at a specific angle θ, and the ion wind generating unit 1 and the ozone removing unit 1b can have a larger air outlet space.

[0029] The ion wind generating unit is arranged on one side of the electronic component and the air outlet 142 faces the electronic component. The ozone removal unit 1b is arranged on the other side opposite to the electronic component and the air inlet 141 faces the electronic component. When in use, the emitter 20 of the ion wind generating unit 1 is electrically connected to the positive or negative pole of the DC power supply, and the collector 30 is electrically connected to the ground terminal or a low potential terminal close to 0 volts. Then, the potential difference between the emitter 20 and the collector 30 of the ion wind generating unit 1 is controlled to be, for example, 5000 to 25000 volts. Under such a high-intensity electric field, the air therein will be ionized or corona discharged to generate a large number of ions. These ions will also be driven by the electric field to push the surrounding air molecules to form an ion wind. However, the high-intensity electric field will also cause the oxygen molecules in the air to be ionized and recombined to form ozone and be pushed by the ion wind to move. The emitter 20 of the ozone removal unit 1b is electrically connected to the positive or negative electrode of the DC power supply, and the collector 30 is electrically connected to the ground terminal or a low potential terminal close to 0 volts, and then the emitter 20 of the ozone removal unit 1b is controlled. The potential difference between the collector electrode 30 is, for example, 500 to 4000 volts. Under such a low-intensity electric field, it is not enough to cause ionization or corona discharge, so no ions are generated, and no ion wind is formed. However, the low-intensity electric field can stabilize the charged particles and promote the decomposition of ozone. For example, when ozone molecules encounter negative ions, they will be reduced to ordinary oxygen, achieving the effect of deozone removal. The ion wind generating unit 1 and the ozone removal unit 1b are respectively arranged on the opposite sides of the electronic component. The ion wind generating unit 1 operates at a high potential difference. The ozone removal unit 1b operates at a low potential difference and decomposes ozone. Therefore, the heat dissipation system can generate ion wind to help the electronic components dissipate heat and remove ozone by itself. In one embodiment, since the ozone removal unit 1b operates at a low potential difference, the conductive brush 22 of the ozone removal unit 1b can be replaced by a conductive rod wire, the two ends of which are connected to the connecting portion 21 and the middle portion is roughly parallel to the conductive rod 31 of the collector 30. The diameter of the conductive rod wire is 0.2 to 3 mm, and its material includes but is not limited to metal, alloy, conductive polymer, carbon material and other conductive materials. The three ion wind generating units 1 are arranged end to end along the y direction. Specifically, the air outlet 142 of the first ion wind generating unit 1 farthest from the electronic component faces the air inlet 141 of the second ion wind generating unit 1 in the middle, and the air outlet 142 of the second ion wind generating unit 1 faces the air inlet 141 of the third ion wind generating unit 1 closest to the electronic component, and the air outlet 142 of the third ion wind generating unit 1 faces the electronic component. Of course, the air outlet 142 of the first ion wind generating unit 1 and the air outlet 142 of the second ion wind generating unit 1 are equivalent to facing the electronic component. The ion wind generating units 1 arranged end to end along the y direction are equivalent to being connected in series and can provide a stronger air volume, but this embodiment is not intended to limit the present invention. As long as the miniaturized electronic product can accommodate If the ion wind generating unit 1 is arranged along the x direction and / or the z direction, as long as the air outlet 142 of the ion wind generating unit 1 faces the electronic component, the ion wind generating unit 1 arranged along the x direction and / or the z direction is equivalent to being connected in parallel and can provide more air volume. The distance between the air inlet 141 and the air outlet 142 facing each other of the two adjacent ion wind generating units 1 is 3 to 20 mm, so as to leave space for the emitter 20 to be electrically connected to the positive or negative pole of the DC power supply, and the collector 30 to be electrically connected to the ground terminal or the low potential terminal close to 0 volts. Specifically, the air outlet 142 of the first ion wind generating unit 1 faces the air inlet 141 of the second ion wind generating unit 1 and the distance is 3 to 20 mm, and the air outlet 142 of the second ion wind generating unit 1 faces the air inlet 141 of the third ion wind generating unit 1 and the distance is 3 to 20 mm. .

[0030] The working principle and use process of the present invention are as follows: during daily use of the cleaning structure 3, the user can control the movable plate 302 to move left and right by pushing the push block 306, and control the air outlet of the ion wind production device 1 by blocking the air outlet of the cone cover 311. When the user needs to clean the dust accumulated on the surface of the blocking net 301, the push block 306 can be quickly pushed left and right. After the push block 306 is subjected to force, it will drive the slider 307 to move left and right along the slide rail 305. The slider 307 will drive the movable plate 302 and the movable plate 308 to move together through the connecting rod 303. When performing the dust cleaning operation, the ion wind generating unit 1 can be temporarily closed. After a period of movement, the movable plate 308 will push the dust on the blocking net 301 through the dust pushing plate 310 set on its back. The dust is processed and concentrated on both sides of the blocking net 301. At this time, the movable plate 302 is opened and the ion wind generating unit 1 is started. When the ion wind is discharged, a part of the wind force enters from the guide block 313, and is discharged outward from the air outlet pipe 312. The discharged wind is inclined downward, and the wind force will blow the dust concentrated on both sides of the blocking net 301 down. The fallen dust will reach the bottom of the device and be blown outward from the guide groove 6. In this way, the dust on the surface of the blocking net 301 can be cleaned, and because the movable plate 308 is also pushed left and right during daily use, there will not be a lot of dust accumulation to affect cleaning. If the shell 2 needs to be replaced later, it only needs to be pulled and disassembled and replaced with a new one.
