Description

Technical Field

[0001] This invention relates to a heat dissipation system for electronic components, and more particularly to a heat dissipation system that generates ion wind to help dissipate heat from electronic components. Prior Technology

[0002] As electronic products become increasingly thinner and smaller, traditional heat dissipation devices such as fans and aluminum fins are becoming less suitable, and fans can also generate noise. Therefore, a heat dissipation device that is more suitable for miniaturized electronic products is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a heat dissipation system for electronic components that can generate ion wind to help dissipate heat from the electronic components, making it a heat dissipation device more suitable for miniaturized electronic products.

[0004] To achieve the above objectives, this invention proposes a heat dissipation system for electronic components. The heat dissipation system includes at least one ion wind generating unit and at least one ozone removal unit. Each ion wind generating unit and each ozone removal unit includes an insulating frame, an emitter, and a collector. The insulating frame includes a top wall, a bottom wall, and opposing side walls, forming an accommodating space. The accommodating space has an air inlet and an air outlet. The inner surface of the side walls forms an inclined surface that slopes inward from the air inlet to the air outlet. The insulating frame also includes a support frame located beside the air inlet and connected at both ends to the side walls. The emitter includes a connecting portion and a conductive brush connected to the connecting portion. The conductive brush is composed of densely arranged conductive fibers, and the connecting portion is disposed on the support frame. The collector includes at least one conductive rod located beside the air outlet and connected at both ends to the side walls. Each ion wind generating unit is located on one side of the electronic component with its air outlet facing the electronic component, and each ozone removal unit is located on the opposite side of the electronic component with its air inlet facing the electronic component. The potential difference between the emitter and collector of each ion wind generating unit causes it to generate ion wind and ozone, and the potential difference between the emitter and collector of each ozone removal unit causes it to decompose ozone.

[0005] In one embodiment of the present invention, the potential difference between the emitter and collector of each ion wind generating unit is 5,000 to 25,000 volts, and the potential difference between the emitter and collector of each ozone removal unit is 500 to 4,000 volts.

[0006] In one embodiment of the present invention, the number of ion wind generating units is two or more, and the distance between the air inlets and air outlets facing each other of two adjacent ion wind generating units is 3 to 20 millimeters.

[0007] In one embodiment of the present invention, the conductive brushes of each ozone removal unit are replaced by conductive rods, with both ends of the conductive rods connected to the connecting portion and the middle portion parallel to the conductive rods of the collector electrode. The diameter of the conductive rods is 0.2 to 3 mm.

[0008] In one embodiment of the present invention, the inner wall surfaces of the two side walls are sequentially formed with a first forward surface, an inwardly inclined surface, and a second forward surface from the air inlet to the air outlet. A convex surface is also formed perpendicularly between the inclined surface and the second forward surface on the inner wall surface of each side wall, and the emitter does not exceed the convex surface.

[0009] In one embodiment of the present invention, the distance between the emitter and the collector is 1 to 10 mm, and the length of each convex surface formed perpendicularly is 1 to 10 mm. The length and width of the connecting portion of the emitter are 2 to 10 mm, and the length of the conductive fibers of the conductive brush is 2 to 10 mm. The diameter of each conductive rod of the collector is 0.5 to 5 mm.

[0010] In one embodiment of the present invention, the conductive brush of the emitter is directed at a specific angle to the conductive rod of the collector. The conductive fibers of the conductive brush include carbon fiber, conductive polymer fiber, carbon black fiber, or conductive metal compound fiber. The conductive rods are made of titanium 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, or Nak80 steel.

[0011] According to an embodiment of the present invention, the heat dissipation system has at least one ion wind generating unit and at least one ozone removal unit having the same structure, which facilitates production and installation. The ion wind generating unit and the ozone removal unit are respectively disposed on opposite sides of the electronic component. The ion wind generating unit operates at a high potential difference to generate ion wind and ozone, which are then blown toward the electronic component to aid in heat dissipation. The ozone removal unit operates at a low potential difference to decompose ozone. Therefore, the heat dissipation system can generate ion wind to aid in heat dissipation of the electronic component and can also self-remove ozone. Furthermore, when the aforementioned structure serves as an ion wind generating unit, the insulating frame is equipped with a support for mounting the emitter, ensuring that the emitter is approximately located in the middle of the insulating frame, thus minimizing leakage to the outside of the insulating frame. The inner wall of the insulating frame has an inwardly inclined surface that slopes from the air inlet to the air outlet, which compresses the incoming air and improves the air ionization effect. The inner wall of the insulating frame has a convex surface at the narrow opening of the inclined surface, which limits the distance between the emitter and the collector, preventing the distance from being too small and causing frequent discharges that would prevent the generation of ion wind. It also reduces the impact of the electric arc generated on both sides of the conductive brush of the emitter. The collector uses a conductive rod, which provides a larger air outlet space. The emitter uses a conductive brush composed of densely arranged conductive fibers. The conductive brush, in conjunction with the conductive rod, can generate ion wind when operating at a high potential difference.

Implementation

[0014] In the following embodiments, the same or similar element symbols represent the same or similar elements. Furthermore, the directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0015] Please refer to Figures 1 through 5 simultaneously. Figure 1 is a perspective view of a heat dissipation system according to an embodiment of the present invention. Figures 2 and 3 are perspective views of an embodiment of the ion wind generating / ozone removal unit of the heat dissipation system shown in Figure 1 from different perspectives. Figures 4 and 5 are respectively an exploded perspective view and an exploded top view of the ion wind generating / ozone removal unit shown in Figure 2. As shown in Figure 1, the heat dissipation system is used for electronic components 2, such as electronic components like chips, or thermal management components such as heat pipes and heat spreaders. The heat dissipation system includes at least one ion wind generating unit 1a and at least one ozone removal unit 1b; in this embodiment, the heat dissipation system includes three ion wind generating units 1a and one ozone removal unit 1b. The ion wind generating unit 1a and the ozone removal unit 1b have the same structure, and therefore can both be marked as component symbol 1. The ion wind generating unit 1a and the ozone removal unit 1b with the same structure can be easily manufactured and installed. The ion wind generating unit or ozone removal unit (referred to as ion wind generating / ozone removal unit) 1 will be described first below.

[0016] As shown in Figures 2 and 3, the ion wind generating / ozone removal unit 1 includes 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 opposing side walls 13, which together form an accommodating space 14. The accommodating space 14 has an air inlet 141 and an air outlet 142. The insulating frame 10 also includes a support 15, which is located next to the air inlet 141 and connected at both ends to the side walls 13. The emitter 20 includes a connecting portion 21 and a conductive brush 22 connected to the connecting portion 21. The conductive brush 22 is composed of densely arranged conductive fibers 23, and the connecting portion 21 is disposed on the support 15. The collector 30 includes two conductive rods 31, each of which is located next to the air outlet 142 and its two ends are respectively connected to the two side walls 13; however, it is not intended to limit the invention. For example, the collector 30 can be modified to include only one conductive rod 31, or it can be modified to include three or more conductive rods 31.

[0017] In this embodiment, as shown in FIG4, the top wall 11 is detachably connected to the two side walls 13; however, this is not intended to limit the invention. For example, the top wall 11 can be fixedly connected to the two side walls 13, i.e., the insulating frame 10 is a one-piece molded 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 may be provided with multiple auxiliary air inlets 111 and 112, which are square and rectangular air inlets, respectively; however, this is not intended to limit the invention. For example, the auxiliary air inlets 111 and 112 can be changed to other shapes such as circular air inlets, as long as these auxiliary air inlets 111 and 112 are not too large and there is no risk of leakage.

[0018] In this embodiment, as shown in Figures 4 and 5, the inner wall surfaces of the two side walls 13 are sequentially formed with a first forward surface 131, an inwardly inclined surface 132, and a second forward surface 133 from the air inlet 141 to the air outlet 142. Viewed from the air inlet 141 to the air outlet 142, the first forward surface 131 of the two side walls 13, together with the top wall 11 and the bottom wall 12, forms a large air intake channel, which can receive a large amount of air. Next, the inwardly inclined surface 132 of the two side walls 13, together with the top wall 11 and the bottom wall 12, forms a gradually narrowing air intake channel, which can pressurize the incoming air and thus improve the air ionization effect. Finally, the second forward surface 133 of the two side walls 13, together with the top wall 11 and the bottom wall 12, forms an air outlet channel, which can output ionized air. In addition, a convex surface 134 can be formed vertically between the inclined surface 132 and the second forward surface 133 on the inner wall surface of each side wall 13. The emitter 20 should not exceed the convex surface 134 when it is set. The convex surface 134 of the two side walls 13 can limit the distance between the emitter 20 and the collector 30, so as to avoid the frequent discharge caused by the small distance between the two and the failure to generate ion wind. Moreover, the convex surface 134 can also reduce the influence of the electric arc generated on both sides of the conductive brush 22 of the emitter 20.

[0019] In this embodiment, as shown in FIG4, 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 position 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 disposed on the support frame 15, the emitter 20 is approximately located in the middle position of the insulating frame 10 and is a certain distance away from the top wall 11 and the bottom wall 12 of the insulating frame 10, which can largely prevent leakage to the outside of the insulating frame 10; moreover, the design of the horizontal support plate 151 and the single vertical support plate 152 takes into account both a large air intake space and the stability of the support frame 15. However, this is not intended to limit the invention. For example, the support frame 15 can be modified to include only the horizontal support plate 151 without the vertical support plate 152, or it can be modified 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.

[0020] In this embodiment, as shown in FIG4, each sidewall 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 two connecting holes 16 of the two sidewalls 13. However, this is not intended to limit the invention. For example, each sidewall 13 next to the air outlet 142 can be modified to be provided with two snap-fit ​​grooves, and the two ends of each conductive rod 31 can slide into the corresponding two snap-fit ​​grooves and slide to the end of the groove to be locked or limited.

[0021] In this embodiment, as shown in FIG4, the connecting portion 21 of the emitter 20 is an elongated connecting portion, and the conductive brush 22 is composed of at least hundreds of conductive fibers 23 with a diameter of micrometers arranged densely in layers along the elongated connecting portion. After the connecting portion 21 is disposed on the support 15, the conductive brush 22 points towards 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 intended to limit the invention. For example, the collector 30 can be modified to include only two conductive rods 31 without the two auxiliary conductive rods 32. In use, the emitter 20 is electrically connected to the positive or negative terminal 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.

[0022] In one embodiment, as shown in Figures 2 and 3, the insulating frame 10 is made of high electrical insulation materials, including but not limited to polymers, composite materials, and ceramic materials. For example, the insulating frame 10 can be made of polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), alumina ceramic, aluminum nitride ceramic, etc. The connecting part 21 of the emitter 20, the conductive fibers 23 of the conductive brush 22, and the conductive rod 31 of the collector 30 are made of conductive materials, including but not limited to metals, alloys, conductive polymers, and carbon materials. For example, the connecting part 21 can be made of copper foil, aluminum foil, etc.; the conductive fibers 23 include but are not limited to carbon fiber, conductive polymer fibers (e.g., polyacetylene fiber, polyaniline fiber, polypyrrole fiber, polythiophene fiber), carbon black fibers, conductive metal compound fibers, etc.; the conductive rod 31 can be made of titanium alloy (e.g., 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. Among them, nickel-plated plastic refers to nickel being electroplated on the surface of plastic, nickel-plated copper refers to nickel being electroplated on the surface of copper, nickel-plated copper alloy refers to nickel being electroplated on the surface of copper alloy, and so on.

[0023] Please refer to Figure 5, which is an exploded top view of the ion wind generating / ozone removal unit 1 shown in Figure 2, omitting the top wall 11 of the insulating frame 10. The design of the convex surface 134 and the connecting hole 16 of the insulating frame 10 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, and the vertical length of the convex surface 134 is 1 to 10 mm. Furthermore, the length and width of the connecting portion 21 of the emitter 20 are 2 to 10 mm, and 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.

[0024] Please refer to Figure 6, which is a cross-sectional side view of the ion wind generating / ozone removal unit 1 shown in Figure 2. In this embodiment, the two conductive rods 31 of the collector 30 are arranged parallel and vertically, and the conductive brush 22 of the emitter 20 points directly to the midpoint of the line connecting the centers of the two conductive rods 31. However, this is not intended to limit the invention. For example, the collector 30 can be modified to include only one conductive rod 31. In this case, the conductive brush 22 of the emitter 20 can point vertically to the center of the conductive rod 31, or it can point at a specific angle to the conductive rod 31 of the collector 30.

[0025] Please refer to Figure 7, which is a cross-sectional side view of another embodiment of the ion wind generating / ozone removal unit shown in Figure 2. Compared to the ion wind generating / ozone removal unit 1 shown in Figure 6, the current collector 30 of the ion wind generating / ozone removal unit 1' shown in Figure 7 includes only one conductive rod 31. Furthermore, the connecting portion 21' of the ion wind generating / ozone removal unit 1' is designed to be bent in a short section facing the current collector 30. Since the conductive fibers of the conductive brush 22' have a micrometer-scale diameter and are easily bent by external forces, this short bent section of the connecting portion 21' forces the conductive fibers of the conductive brush 22' to bend, causing the conductive brush 22' to point at the conductive rod 31 of the current collector 30 at a specific angle θ. The ion wind generating / ozone removal unit 1' can have a larger air outlet space.

[0026] After explaining the ion wind generating / ozone removal unit, please refer back to Figure 1. The following will explain the heat dissipation system. The ion wind generating unit 1a is located on one side of the electronic component 2, and the air outlets 142 all face the electronic component 2. The ozone removal unit 1b is located on the opposite side of the electronic component 2, and the air inlet 141 faces the electronic component 2.

[0027] In use, the emitter 20 of the ion wind generating unit 1a is electrically connected to the positive or negative terminal of a DC power supply, and the collector 30 is electrically connected to the ground terminal or a low potential terminal close to 0 volts. The potential difference between the emitter and collector of the ion wind generating unit 1a is then controlled to, for example, 5000 to 25000 volts. Under such a high-intensity electric field, the air within is ionized or corona discharged, generating a large number of ions. These ions are also driven by the electric field to push surrounding air molecules, forming an ion wind. However, the high-intensity electric field also causes oxygen molecules in the air to be ionized, recombine, and form ozone, which is then propelled by the ion wind.

[0028] Similarly, the emitter 20 of the ozone removal unit 1b is electrically connected to the positive or negative terminal of a DC power supply, and the collector 30 is electrically connected to the ground terminal or a low potential terminal close to 0 volts. The potential difference between the emitter and collector of the ozone removal unit 1b is then controlled to, for example, 500 to 4000 volts. Under such a low-intensity electric field, ionization or corona discharge is insufficient to be triggered, therefore no ions are generated, and thus no ion wind is formed. However, the low-intensity electric field can stabilize charged particles and promote the decomposition of ozone. For example, ozone molecules are reduced to ordinary oxygen when they encounter negative ions, achieving the effect of ozone removal.

[0029] In simple terms, the ion wind generating unit 1a and the ozone removal unit 1b are respectively disposed on opposite sides of the electronic component 2. The ion wind generating unit 1a operates at a high potential difference, generating ion wind and ozone, which is then blown onto the electronic component 2 to aid in heat dissipation. The ozone removal unit 1b operates at a low potential difference, decomposing ozone. Therefore, the heat dissipation system can generate ion wind to aid in heat dissipation of the electronic component 2 and can also remove ozone 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 this conductive rod wire are connected to the connecting part 21, and the middle part is approximately parallel to the conductive rod 31 of the collector 30. The diameter of this conductive rod wire is 0.2 to 3 mm, and its material includes, but is not limited to, conductive materials such as metals, alloys, conductive polymers, and carbon materials.

[0030] In this embodiment, three ion wind generating units 1a are arranged end-to-end along the y-direction. Specifically, the air outlet 142 of the first ion wind generating unit 1a furthest from the electronic component 2 faces the air inlet 141 of the second ion wind generating unit 1a in the middle. The air outlet 142 of the second ion wind generating unit 1a faces the air inlet 141 of the third ion wind generating unit 1a closest to the electronic component 2, and the air outlet 142 of the third ion wind generating unit 1a faces the electronic component 2. Similarly, the air outlets 142 of the first and second ion wind generating units 1a also face the electronic component 2. This arrangement of ion wind generating units 1a end-to-end along the y-direction is equivalent to connecting them in series, thus providing a stronger airflow. However, this embodiment is not intended to limit the invention. If a miniaturized electronic product can accommodate them, ion wind generating units 1a can also be arranged along the x-direction and / or z-direction, as long as the air outlet 142 of the ion wind generating unit 1a faces the electronic component 2. The ion wind generating units 1a arranged along the x-direction and / or z-direction are equivalent to being connected in parallel, thus providing more air volume.

[0031] In this embodiment, the distance between the air inlets 141 and outlets 142 of two adjacent ion wind generating units 1a is 3 to 20 mm, so as to leave space for the emitter 20 to be electrically connected to the positive or negative terminal of the DC power supply, and the collector 30 to be electrically connected to the ground terminal or a low potential terminal close to 0 volts. Specifically, the outlet 142 of the first ion wind generating unit 1a and the air inlet 141 of the second ion wind generating unit 1a face each other and are spaced 3 to 20 mm apart, and the outlet 142 of the second ion wind generating unit 1a and the air inlet 141 of the third ion wind generating unit 1a face each other and are spaced 3 to 20 mm apart.

[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
