Abstract

Surfaces for electromagnetic shielding, retaining electrostatic charge and indeed collecting ion current in EHD fluid mover designs may be formed as or on surfaces of other components and/or structures in an electronic device (e.g., 100, 700, 1000). In this way, dimensions may be reduced and packing densities increased. In some cases, electrostatically operative portions (e.g., 392, 393, 792, 793, 794, 1192, 1193 and/or 1194) of an EHD fluid mover (e.g., 110, 310, 710, 910, 1010A, 1010B) are formed as or on surfaces of an enclosure, an EMI shield, a circuit board and/or a heat pipe or spreader. Depending on the role of these electrostatically operative portions, dielectric, resistive and/or ozone robust or catalytic coatings or conditioning may be applied.

These and other embodiments will be better understood by reference to the embodiments, drawings, and riding towels herein. [Embodiment] It is understood that many of the designs and techniques described herein are particularly useful for the thermal management of densely packed devices and small modern consumer electronic devices. In fact, some of the EHD gas miscellaneous design and technology can contribute to the active thermal management of electronic devices, because the thinning of electronic devices or industrial design limits mechanical airflow devices (such as fans, blowers, etc.) The fate of life. In some embodiments, such an EHD airflow device can be fully integrated into a system, such as a tablet or portable computer, a projector, or a video display, a set-top box, and the like. In other embodiments, such an airflow arrangement may be in the form of a subassembly having an EHD turbulent flow or a housing. In terms of the above, it can be constructed to provide a variety of sizes, geometrical functions, and design of the static crane wire that constitutes the thief electrode, and can conceive various electrostatic operations of a given device. Check the mutual _ between the surface and the electrode and/or the H electrode. For the sake of explanation, it is more difficult to position the position between the table money and other components of the specific mosquito. For example, 'in most of the money, the opposite is flat, the collector electrode is formed on the inner surface of the casing or electromagnetic interference (dish), cover or _ circuit board (PCB) county silk surface, and A parallel surface that is placed close to the corona discharge type of emitter wire that is misaligned with the front end of the 彳_retraction electrode. Nonetheless, other embodiments described herein may employ other electrostatically operated surface reduction techniques as their _ sub-generation techniques, and still be understood. In this application, certain aspects of the described embodiments are referred to as electrohydrodynamic fluid acceleration devices, also referred to as "EHD" devices, "sputum fluid accelerators", "EHD airflow devices", and the like. For purposes of illustration, some embodiments have a specific EHD device that has a wiper located at or near the (four) electrode to generate ions that will be accelerated in the presence of an electric field, thereby driving fluid flow. . It should be understood that even if this scheme disposes of a corona type device, other ion generation techniques can be applied. For example, in some embodiments, for example, silent discharge, AC discharge, dielectric barrier discharge (dbd), etc., can be used to generate ions that are accelerated when an electric field is present, thereby driving fluid flow. 12 201205434 A second to see the use of a heat transfer surface (in some embodiments, the heat transfer of the Korean plate purchases (10) to repair n, _ units, etc.) and / or other 7L pieces of heat can be dissipated The fluid flow transferred to the EHD drive is discharged from the housing through the exhaust rim. In general, when the thermal management is in the middle of the operation 3, the heat transfer path is set in the housing (usually 2 heat pipes or the implementation of the tilting process). To its towel, an EHD device (a device (4)) drives airflow through one or more locations on the heat transfer surface. ...to illustrate the heat transfer (10) panels of various examples. However, it is known from the month (3) that in some embodiments, it is not necessary to provide a conventional heat sink two array. j _E_EHD-driven fluid flows through the exposed internal surface, providing adequate heat transfer, whether close to or removed from a heat-generating device such as a microprocessor, memory, ie, part, optoelectronic or (four) source . In each of the obstacles, the red person provides an ozone catalyst or a reactive surface/material on the heat transfer surface. In general, the heat transfer surface of the emitter electrode, the field shaping surface, and the ion-receiving surface exhibit no design challenges and can be set to different structures or different surface conditions relative to other shell examples. However, in a twoteenth case, the 'single-structure can be electrostatically operable (e.g., to shape the field or collect away) and provide a squama EHD flood-fluid flow. It should be noted that in some Yang Feng's implementation, EHD-driven flow can be mixed, and can be transferred to the surrounding environment for servant or defamatory. In this way, even if there is no apparent flow through the exhaust rim, the outer surface of the housing is less susceptible to lightening. Of course, in some implementations, the EHD's Vietnamese hotspots and 13 201205434 exhaust heat to the airflow to the exhaust edge by forced convective heat transfer.

The EHD airflow device design described herein may include one or more corona discharge type transmitter electrodes. In general, such corona discharge electrodes comprise a portion (or portions) exhibiting a small radius of curvature and are in the form of wires, rods, edges or points. Other shapes of the corona discharge electrode are also possible; for example, the corona discharge electrode can be a hook wire, a wide metal strip, a saw blade having a sharp or thin portion, or a non-saw plate to assist in applying a high voltage. The ions are generated at an electrode having a small radius of curvature. In general, corona discharge electrodes can be fabricated from a wide variety of materials. For example, in some embodiments, Krichtaf〇vitch et al., U.S. Patent No. 71,577, 4, issued toK. The composition of 201205434. The _ _ 715 is hereby incorporated to illustrate the materials that can be used for the (four) electrode of certain corona discharge type embodiments. In general, a high voltage power source creates an electric field between the corona discharge electrode and the collector electrode. The EHD airflow design described herein includes an ion collecting surface located downstream of one or more corona discharge electrodes. Typically, the ion collecting surface of the helium gas flow device comprises a substantially planar guiding surface of the collector electrode that extends downstream of the corona discharge electrode. 4 In some cases, the collector electrode can be doubled like a heat transfer surface. jobs. In some cases, a fluid permeable ion collecting surface can be provided. In general, the collector electrode surface can be made of any suitable electrically conductive material, such as ingot or copper. Or, as described in U.S. Patent No. 6,919,698 to Krichtaf 〇vitch, the collector electrode (herein referred to as the "acceleration" electrode) can utilize a high-conducting body, which can be used to conduct light currents, but along the High-impedance (four), the electrode material body (four) flow path of the voltage cake will reduce the surface potential, _ suppression is to close her discharge event. Such relatively high-impedance materials include _filled carbon, seconds, gallium, phosphide, nitriding, carbonized stone, and lithograph. The material of the collector electrode that can be used in certain embodiments is described herein in conjunction with U.S. Patent No. 9,969,. It should be noted that some of the actual wipes may be adjusted or coated on the surface of the high-impedance material.

Of course, the airflow layout shown is merely an example, and more generally the 'airflow layout' may be determined by the domain configuration of the components, the challenges posed by the particular device, and/or the design factors of the industry. Figure 2C shows a variation in which the airflow layout includes a circulating airflow composition 202A and an airflow 202B that passes through the exhaust edge 251 and the ingress and egress means. Other thin and low profile curves or high aspect ratio devices are also contemplated. For example, FIG. 7A is a perspective view of an illustrative portable consumer electronic device 7A, wherein an EHD airflow device is disposed at a body portion having a total thickness d of less than about 10 mm, according to some embodiments of the present invention. Inside. Figure 7a shows an exemplary inflow 702 and outflow 703 that can be designed and installed in accordance with the inventive concept of the present invention to be driven by a limited_light_EHD airflow device 71() and 201205434 through the consumer electronic device. In some embodiments, the available internal volume and/or assembly only allows the total thickness d of the EHD airflow device 710 to be 5 mm or less. Of course, the locations of the inflow, outflow, and heat transfer surfaces 720 shown are merely examples. More generally, the exhaust edge may be determined by the internal configuration of the component, the challenges posed by the particular device, and/or industrial design factors. Figures 7B and 7C (above plan view) show the airflow layout and configuration of the EHD airflow device 710, with individual electronic components, such as keyboard components 74, and circuit boards 730 and/or radio frequency (RF) of the processor (e.g., CPU, GPU, etc.) The location (eg, WiFi, WiMax, 3G/4G voice/data, GPS, etc.) is toward the upper edge of the body portion 701A, and some of the edge of the exhaust edge (eg, inlet 751 and outlet 752) are disposed therein.

In some embodiments, the available internal volume and/or assembly only allows the total thickness d of the EHD airflow device 1010 to be 5 mm or less. Of course, the locations of the inflow, outflow, and heat transfer surfaces shown are only examples.

To the airflow (10〇2, Cong) driven by the EHD airflow devices 1010A, 1010B.

The above-mentioned tablet type, portable type, and television type consumer device are merely illustrative. In fact, it will be apparent to those skilled in the art <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; Or a conversion type of industrial design factors for a given design). In light of the foregoing, we have designed the EHD airflow device to be suitably integrated into a consumer device of limited thickness. 19 201205434 EHD airflow device design plate type device embodiment&gt; FIG. 1A and the flat type consumer electronic device 100 shown therein, see several (four) fluid (or airflow) attacks in the description of FIGS. 3, 5, and 6. The cross section of the configuration _ 'where the static part of the design is the table formed in the apparatus 1. In some cases, at least the portion of the bribe is formed on the surface of the casing itself. In some cases, at least one of the electrostatically operated portions is formed on an EMI shielded surface that covers an electronic component, such as a circuit board or display device. In each case, the EHD fluid H device can be accommodated in a very limited internal space by placing the static electricity on the surface of the job. For example, in a thin low profile or a high aspect ratio consumer electronic device (such as those shown in Figures 3, 5, and 6), the total thickness d is preferably less than about 10 mm, and the integrated body is installed. Printed circuit boards (PCBs) for circuits, pellets, connectors, etc. occupy the ribs empty. Examples of pcBs with integrated circuits include a central processing unit (CPU), a processing unit (Gpu), a communication processor and a transceiver, a memory, etc., which often generate most of the thermal load. 'And in some implementations, the 'storage' is cooled by an EHD fluid/airflow device placed very close to the heat source (or thermally coupled to the fin/heat sink). 20 201205434 In some cases, as shown in Figure 3, the desired one is to accommodate 1 display 301; (ii) double-sided PCB 361 (with integrated integrated circuit 362, 363, 364, shot 365, connection 1 § 366); (iii) EHD airflow device 310 is in a stack and volume of devices at least partially enclosed by housing 309. Although in general, the available internal volume and valley space are related to the examples and designs, it should be understood from the figures and description that the consumer electronic device can allow the EHD airflow device 31 to occupy a total thickness of 5 mm or less. d. In some embodiments, the thermal transfer (Ητ) fins 320 can also be sized to fit a limited thickness. Figure 4 (in schematic form) shows an illustrative configuration in which a high voltage power supply 491 is coupled between the emitter electrode 491 and the collector electrode 492 to generate an electric field, and in some cases the ion will generate ions 'substantially along The fluid flow 499 is driven in a downstream direction. In this figure, the transmitter electrode 491 is coupled to the positive high voltage terminal of the power supply 491 (eg, +3.5 KV, although this is a particular voltage value, but virtually any power supply waveform can be provided depending on design choice), and the collector electrode 492 Lightly attached to the near ground. Given a large voltage difference between a transmitter electrode 491 and the guiding surface of the collector electrode 492 and a very short distance (approximately or more), a strong electric field can be generated which will be positively charged for the fluid (or r Sub) produces a driving force downstream. The field lines show (substantially) the two orientations of the final electric field' and the gaps of the indicated field lines are used to indicate the intensity. It is known to those skilled in the art that the principle of the discharge of the material can be generated in a strong electric field near the surface of the emitter electrode of the electro-discharge type to be generated from 201205434. Thus, in the embodiment of the corona discharge type according to Fig. 4, fluid molecules (e.g., surrounding air molecules) near the emitter electrode 491 are ionized, and the final τ positively charged ions are accelerated in the electric field toward the collector electrode. Depending on the impact fluid molecules in the impact treatment. The result of enthalpy is that the momentum of the ions is transferred to the neutral fluid molecule 'the fluid molecules move downstream. When collector electrode 492 attracts positively charged ions and neutralizes them, the fluid molecules of the blanket move at a speed that is not exceeded by the (4) electrode (e.g., Zhao does not flow). The fluid transfer caused by corona discharge can be referred to differently as "electron", "corona", or "ion" wind and is generally defined as the movement of gas from the movement of ions near the high voltage discharge electrode. . Although the description is focused on the configuration of the emitter electrode of the corona discharge type, it is well known to those skilled in the art that it is generated by other sources, such as silent discharge, AC discharge, dielectric wall discharge (DBD), etc., and - but The ions are generated and then accelerated by the electric field to drive the fluid axis as described herein. In order to avoid confusion, the emission of the H electrode does not require a wire corona discharge. The voltage magnitude, polarity, and waveform (if any) of the power supply described in the specific embodiments are merely illustrative and may differ from those described in other embodiments. Some embodiments may be further understood if the specific surface disposed upstream of the emitter electrode 491 is shaped to shape the aforementioned electric field and/or the barrier is disposed upstream of the ion movement. For example, with respect to Fig. 4, a dielectric surface A% may be provided, and positively charged ions generated in the case of the corona discharge type emitter electrode 22 201205434 491 are easily accumulated on the dielectric surface 493. Since the dielectric surface does not provide a grounded attraction path, it is easy to accumulate a net positive charge and then operate as an electrostatic charge to reject the same charge. Thus, the electrostatically operated dielectric surface 493 acts as a barrier to ions moving upstream. The upstream dielectric surface 493 can also electrostatically shield other grounded attraction paths, so that the aforementioned electric field is oriented primarily toward the downstream of the collector electrode 492. In order to improve performance, there is an air gap between the leading edge of the collector electrode 492 and the adjacent portion of the dielectric surface 493. For example, in some embodiments, the dielectric surface is formed in the willow, and the palpitations H and the air gap are as shown in Fig. 4. Alternatively, in some embodiments, one or more of the two circuits may be placed upstream of the dielectric surface 493 to complete the 494 峨 orientation of the upstream machine. In some embodiments of certain ventilation devices, the grounded conductive path may be placed adjacent to the inlet aperture. ... soil; month Hanming' Now, with reference to Figure 3, it can be found in the commercially preferred.

For example, in some embodiments, the sputum is electrically conductive (eg, gold &gt;!) or stripped on a substantially electrically conductive housing (or surface) surface that is grounded to form a first collection. The electrode is substantially concentric and can cut the conductive strip or strip to the desired shape and amplitude for the collector electrode 392.

The (eg, dielectric) layer may be secretly or selectively removed 'to expose the desired shape and amplitude of the collector electrode 392. In some cases the 'grounded conductive layer or portion may be with the shell The body is integrally formed. The second higher collector electrode 392 can be similarly formed on the EMI mask 3〇8 (or a portion thereof), and the EMI mask is used to separate the nano airflow device 31〇 and the product fixed on the double-sided PCB 361. Body circuit (362, 363, secret), shot 365, and/or connector 366. A conductive (eg, metal) strip or strip may be attached to the non-conductive exposed surface of the mask 308 and surfaced to the ground. Forming a second collector electrode. Or, other covering the inner layer of the grounding guide such as metal) A non-conductive (e.g., dielectric) layer that is an EMI shielding region can be secreted or selectively removed to expose the desired shape and amplitude of the collector electrode 392.

As described with reference to Figure 4, the dielectric surface is electrostatically operated. Sexually, and can contribute to the field shaping of the EHD airflow device, while providing an upstream barrier for ion movement. Further, during operation of the EHD airflow device 31, the dielectric surface 393 accumulates charge (eg, from corona discharge) Types of emitter electrodes form positive ions.) Because dielectric surface 393 does not provide grounded attraction control' then the net charge tends to accumulate and can then be electrostatically operated to reject the same charge. Thus, dielectric surface 393 The electrostatically operable ions move the upstream barrier. The upstream dielectric surface 493 can also electrostatically shield other grounded attraction paths, such as leads formed on the PCB 361, components fixed to the pcB 361, and electricity. 367, the housing 309 or other electronic components not explicitly shown, whereby the electric field can be molded to be mainly in the downstream direction of the collector electrode 492. Like the collector electrode 392 'the dielectric surface 393 can be formed in the foregoing Formed on or in the body. In each case, by forming the electrostatic collector surface of the shaft collector electrode 392 and the dielectric surface 393 on the surface, the EHD airflow device 31 can be included in a very limited internal space.

In some airbags, such a heat sink and heat transfer fins 32 () are provided in a manner as shown in FIG. In this case (and considering the size of the gap), the desired person is to set the thermal buffer 3〇7 (such as closed-cell bead plastic or other insulation material) to avoid the hot spot of the shell and guide the EHD-driven fluid flow. Transfer the fins through the heat.

Listening port 3 and 6 26 201205434 Portable embodiment θ 7A 7B, 7C &amp; 5 brothers of the portable type of consumer electronic wear 7 〇〇 (and body part 7 〇 1A), now with a horizontal view i 9A and the composition of the EHD airflow device, wherein the electrostatically operated portion of the design is formed on the surface of the device housing. In some cases, at least one of the electrostatic handling impurities is formed on the wire of the casing itself. In some cases, at least - Chuan County is a complex surface on the form of electronic electronics (such as the plate assembly or board). In each case, the electrostatic operation unit is located on the county surface, and the Effl fluid/air flow device is placed in a very limited internal space. For example, in a cross-sectional view of the body portion of a consumer electronic device such as that shown in Figures 8A and 8C, the total thickness d is less than about 10 mm, and the keys i, 'and the portion 74G occupy the available vertical space-portion. Recall the planar layout of Figures 7c' ϋ 8A and 8 (the thin cross-section allows for substantially full side vertical space to accommodate the EHD airflow device 710. On the other hand, Figures 9Α and 9Β are not tighter (4) The printed circuit board (pcB) with integrated circuit, pellets, connectors, etc., which occupies the airflow devices 71〇 and 6, occupies most of the available internal space. Examples of PCBs include central processing unit (CPU), ® physics unit (GPU), communication processor and transceiver, memory, etc., which often generate large beta-knife devices that are hot-loaded and In an embodiment, the filaments are cooled by an EHD fluid/airflow device disposed at a very low heat source (or heat transfer to the fin/heat sink). Referring first to the cross-section of Figure 8A, a pair of substantially flat collections The electrode 792 is formed on the opposite inner surface of the bottom portion 7〇1A. More specifically, the first lower collector electrode instance 792 is formed on a portion of the inner surface of the housing 7〇9. In some embodiments, the conductive (eg, metal) strip or strip can be secured Substantially non-conductive housing or internal surface of the surface, and coupled to ground to form a first collector electrode instance. In general, the conductive strip or strip can be cut to the desired shape and amplitude for use. The collector electrode 792 ° or other non-conductive (eg, dielectric) layer overlying the grounded conductive (eg, metal) layer or region may be "removed" or selectively removed to expose the collector electrode 792 The desired shape and amplitude. In some cases, the grounded conductive layer or portion may be formed integrally with the housing 709. The second comparison may be similarly formed on the EMI mask 708 (or a portion thereof). A high collector electrode 792, an EMI mask 708 isolating the EHD airflow device 71 and the keyboard assembly 740. A conductive (eg, metal) strip or strip may be attached to the non-conductive exposed surface of the shield 708 and coupled to the ground to form Second collector electrode. As previously described, the cleavable conductive strip is of a desired shape and amplitude for the collector electrode 792. Alternatively, the other covers the grounded conductive (e.g., metal) inner layer or EMI shield 708 region. Non-conductive (eg The electrical layer 28 can be etched, or selectively removed, in shape and amplitude. The emitter electrode 791 exposing the desired end of the collector electrode 792 is not clearly shown. The above is explained as _ to generate the embossment of the embodiment ______3 ion. For example, in some embodiments, the transmitter electrode (four) κν, which is otherwise specific, can provide any power waveform according to design choices, and the electrode 792 is applied to the proximal ground. The operation of the coffee flow can be described with reference to Figure 4. For the collector electrodes, the upper and lower examples of the dielectric surface 793 are disposed on or in the portion of the surface of the shield 708 or the housing. This f dielectric sluice operation, and has a 'sound' for the field shaping of the EHD flow miscellaneous and also sets a barrier for the ions to move upstream. In particular, during operation of the EHD body j 71G, the dielectric surface 793 will accumulate charge (e.g., the positive displacement = generated by the example of the corona discharge type 791 or other type of corona discharge type). Thus, the dielectric surface 793 can be electrostatically operated as a resistance to the upstream movement of ions. The upstream dielectric surface 793 also tends to electrostatically shield any other suction path to ground, such as keyboard assembly 740, battery 767, housing 709 itself, or portions of other electronic components not shown. In this manner, dielectric surface 793 can be molded 29 201205434 so that it is oriented primarily toward the collector electrode-shaped EHD airflow device to establish the electric field, 792 direction. The venting inflow 702 of the 'air" passes through the keyboard assembly. Figure 8B shows the hole 7% in the upper dielectric surface 793. In Figure 8A, the hole of the 740 passes. Partial bottom view of the figure &amp; (from the internal view of the fine airflow device). Although shown as a recirculating aperture array, it is well known to those skilled in the art that various perforations (and styles thereof) of the upper dielectric surface 793 can be provided to assist in venting the inflow 702. It is also known that the electrostatically charged accumulated charge on the dielectric surface 793 described above can provide a barrier to the ion movement of the EHD airflow device.

In some implementations, the ray can be woven. For example, in Figure 8A, the additional ion repellent barrier is a gas permeable screen for the upstream cross-section of the dielectric, grid, grid or other fluid that is driven across the EHD. As previously described, the barrier 795 accumulates charge (e.g., positive ions generated by the example of the corona discharge type of the emitter electrode 791), and the helium operation is an electrostatic barrier that moves ions upstream. In the configuration, a grounded conductive path 794 is provided to capture ions moving upstream through the barrier 795. In some embodiments, a sub-assembly structure (not explicitly shown in Figure 8A) may be provided (e.g., to fix the position of emitter electrode 791 and collector electrode 792 relative to each other). Figure 8C is a cross-sectional view through the illustrative housing structure 811 (e.g., a portion of the subassembly housing) that allows the collector electrode 792 and the position of the transmitter 209210544 emitter electrode 791 to be fixed relative to one another. Note that the fixed points (e.g., 812) of the individual ends of the emitter 79i must be placed outside of the cross-section shown, but can be better understood from the cross-section of the corresponding perspective of Figure 8D. As previously discussed, the electrostatically operated upper and lower dielectric surfaces 793 facilitate field shaping of the EHD fluidic device and also provide barriers to ions moving upstream. However, in the variant of Fig. 8c, the dielectric surfaces 793 are superimposed on the - part of the housing structure 8 shown and are directed to (as previously described) their scuttles or It is an upstream direction of the surface of the casing 7〇9. Note that in the stereogram of the figure, only the overlapping electrostatic field-changing dielectric surface 793 is shown below. In some embodiments, the polyimide film or strip may be in the form of a tape or a plurality of dielectric surfaces as shown, for example, emours A is sold as a kapton trademark. Or individual parts of the housing. In the foregoing embodiments of Figures 8A and 8C, the internal space of the commercially preferred form factor thermal management solution is of very limited thickness, wherein 'the surface of the crane is used for the surface (for example, the collection field is field and can be collected The surface of the electric f) is rich, and the precious thickness is miscellaneous. Otherwise, the work will be wasted in the wall of the package electrode in the coffee flow device. Do this

Although the available internal space and tolerance are generally dependent on utility and design 'should be able to It is clear from the drawings and description that the consumer electronic device can tolerate 5 mm or less of its total thickness d for the EHD airflow device 910. In some embodiments (e.g., as shown in Figure 9A), thermal transfer The fins 920 can be sized to accommodate a limited thickness. In some embodiments (as shown in Figure 9B), the airflow path can mount a larger heat transfer fin 920. In each case Forming the electrostatically-operated surface as the collector electrode 792 and/or the dielectric surface 793 on the aforementioned surface, the EHD airflow device 91 can be included in a very limited internal space, as shown in Figures 9 and 93, respectively. As mentioned before, even though The layout is omitted here, and the outer casing structure (e.g., a portion of the subassembly housing) can position the collector electrode 792 and the emitter electrode 791 relative to each other. In this case, the dielectric surface 793 (e.g., The poly-branched film or tape can be overlaid on the _ portion of the outer casing structure (not explicitly shown, but can be seen in Figures 8C and 8D), and can consistently face the surface of the EMI shielding 908 (or part thereof) The upstream direction extends. TV or display device embodiment Referring again to FIGS. 10A, 10B and 11A and the flat panel display device 1000' shown therein, the display for FIGS. 11B and 11C will be explained (in cross-sectional view). 201205434: The EHD airflow at the bottom and top of the device is lightly constructed, wherein the electrostatically operated surface of the design is applied to the surface of the device shell. In a certain case, at least one static mess is formed on the wire of the shell itself. In a certain situation, the operation part of the saki electric power is formed on a simple light wire covering an electronic component (for example, a display). In each case, the EKD flow evaluation device is provided by the electrostatic operation part shaft (10) Can be installed in a very limited internal space For example, in the face of the flat panel display device, the cross section 11B and the lie', 'the ice degree d is less than about 1 mm. Recall the perspective view of Fig. 11A and the top and bottom EHD airflow devices shown in Fig. 11B. Cross section 11β, wherein the inner depth of the king accommodates a bottom EHD airflow device ι〇ι〇Α ^ Figure 11C similarly shows the cross section 11C' where the display surface 1〇〇1 and the top EHD airflow device 1010B are accommodated in the flat plate In the internal depth of the display device 1000. In the bottom-to-top airflow shown, the top EHD airflow device 1010B is accommodated in the space behind the display surface 〇〇1, and its electrostatic operating features are compared to the bottom EHD airflow. Similar features of device 1010A are more densely packed. In any case, the design and operation of individual airflow devices are very similar. In the case of the EHD airflow device 1010 (see Figure 11B), the electrostatically operated surface can be formed (at least partially) over the subassembly structure. As previously described, the outer casing structure (e.g., a portion of the subassembly housing) allows the collector electrode 1192 and the emitter electrode 1191 to have a fixed relative position relative to each other. In this case, the dielectric surface 1193 (eg, poly film or tape) may overlap the portion of the outer casing structure and may be placed toward the surface of the EMI shielding 1109 (or - Partial) extends in the upstream direction. Alternatively, although the flat collector electrode 1192, which is not explicitly shown in Fig. 11B, may be formed or formed directly on the opposing inner surface of the housing 1109. In certain embodiments of the flat panel display 1A, a conductive (eg, metal) f or strip may be fixed to be substantially non-conductive, as described herein for a particular collector electrode design for a flat panel type and portable type device. The inner surface of the housing (or its surface) is grounded and grounded to form each collector electrode 1192. Typically, Q, the conductive strip or strip can be cut to the desired shape and amplitude for the collector electrode 1192. Alternatively, other non-conductive (e.g., dielectric) layers overlying a grounded conductive (e.g., metal) layer or region may be etched or selectively removed to explode the desired shape and amplitude of the collector electrode 1192. . In some cases, the grounded conductive layer or portion may be integrally formed with the housing 11〇9. For EHD airflow device 1010B (see Figure 11C), first collector electrode instance 1192 is formed using any of the described methods, while second collector electrode instance 1192 is formed on or formed on EMI shield 11〇8 In part, the EMI shields 11〇8 to isolate the EHD airflow device 1010B from the display surface. Although provided in some embodiments, the housing structure of the EHD subassembly is omitted in order to simplify the drawing. As previously mentioned, a conductive (e.g., metal) strip or strip can be attached to the exposed surface of the EMI shield 1108 and grounded 34 201205434 to form a second collector electrode instance 1192. As also previously described, the conductive strip or strip can be cut to the desired shape and amplitude for the collector electrode 1192. Alternatively, other non-conductive (eg, dielectric) layers overlying the grounded conductive (eg, metal) inner layer or EMI shield 11〇8 region may be etched or selectively removed to expose the collector electrode 1192. The shape and extent of desire. For the EHD airflow device 1010A and the EHD airflow device 1010B, an example of the individual collector electrode 1192 and the transmitter electrode 1191 are coupled between the two ends of the voltage source (although not explicitly shown, reference may be made to FIG. 4) To generate an electric field and (as in the embodiment of the corona discharge type described) ions, which can drive the gas flow in an upstream direction substantially as shown. In some embodiments, the transmitter electrode example 1191 is a high voltage power supply (one of which is +3 5 κν, which can actually use any voltage waveform regarding the remote selection), as in the aforementioned flat type and carry type design. The positive terminal, and the collector electrode is 11% coupled to the proximal ground. The operation of the EHD airflow device 1 can be as described in Figure 4. 35 1 As the collector electrode, the opposite interface The electrical surface 1193 is formed on or formed as part of the EMI mask or the exposed surface of the housing. These dielectric surfaces are electrostatically operable and contribute to the individual excitation airflow. The shaping field also prevents ions from moving upstream. In particular, during operation of the coffee flow device faces A and 1010B, the individual dielectric surfaces U93 accumulate charge (eg, a simple example of a transmitter electrode from corona discharge) 201205434 Formed positive ions). Shame, meso-surface 1193 statically acts as an ion/moving upstream obstacles' and the suction path of the stomach to the female ground is only for example the body 11〇9 itself or (special In the case of the coffee airflow device) Or other electronic yokes not explicitly shown. The individual dielectric surfaces (10) of the moldable gas flow devices 1010A and 1010B are mainly oriented in the downstream direction (above nA and 11B) to face individual Collector electrode (10). It is also possible to slap additional ion movement barriers. For example, in Figure 1 and the additional ion repellent barrier 1195 as a dielectric grid, grid, peach or its cross-EHD driven fluid The gas permeable screen of the upstream cross section. As described above, the P guide wall 1195 accumulates electric charges (positive ions generated at the corona discharge type emitter electrode 1191 or elsewhere), and operates as a static resistance barrier in which ions move upstream. A grounded conductive path 1194 is provided to capture the ions that move upstream beyond the barrier 1195. Although the available internal space and tolerance are substantially dependent on the utility and the setting ten, the month should be It is clearly understood that the consumer electronic device can tolerate 5 mm or less of the total thickness d of the EHD airflow device 1() i〇B and 1010A.
