[0045] Embodiments according to the drawings will be described in the following with reference to the drawings.

[0046] In various embodiments of the present application, an ozone generator, such as a gas corona discharge type ozone generator, is provided, which comprises one or more plate-type ozone generation units, among others.

[0047] Reference is made to FIGS. 1A-1G , which shows an ozone generator 1 according to an embodiment of the present application, which is, for example, an integrated ozone generator.

In some embodiments, the current output from the power supply module 6 is boosted through the high-voltage transformer 7 and the resonant inductor 8 to achieve the high voltage required by the plate-type ozone generator module 2.

[0052] It will be understood that ozone generators may optionally be equipped with the aforementioned or other processing circuits, transformer mechanisms, and / or power conversion modules, as well as other functional components related to the power supply and monitoring of the ozone generator, which will not be elaborated upon here.

(Continue to the previous section) FIGS. 1A-1G The ozone generator 1 may include a heat dissipation device 131 (such as a cooling fan) disposed on the top panel 13.

[0055] People will understand that the ozone generating unit (also referred to as "ozone generating module") of the embodiments of the present invention can be applied not only to, for example, FIGS. 2A-13C The integrated ozone generator shown can also be applied to other types of ozone generators or combinations or arrays of different ozone generators, which fall within the scope of this invention.

[0056] For example, in another embodiment, a rack-mounted ozone generator may be provided, which may include a rack, multiple ozone generating units, a gas distribution system, and a cooling fluid distribution system. In this rack-mounted ozone generator, the multiple ozone generating units may share one or more sets of electrical components.

[0058] Reference FIGS. 3A-4D This document describes an ozone generating unit 2 according to a first embodiment of the present invention. In the illustrated embodiment, the ozone generating unit 2 may be configured as a plate-type ozone generating unit, and it may be modular, and may also be referred to herein as an ozone generating module.

[0059] In the illustrated embodiment, the ozone generating unit 2 may include multiple stacked ground electrodes, which are plate-type ground electrodes, as described below. FIGS. 3A-3C As stated above.

[0060] Ozone generating unit 2 may also include a high-voltage discharge assembly disposed between the ground electrodes, as described below. FIGS. 5A-10B as well as FIGS. 3A-3C As stated above.

[0061] Accordingly, such as FIGS. 2A-2C As shown, the ground electrode 20 and the high-voltage discharge assembly 21 can together form a discharge chamber for the discharge reaction.

[0062] In the illustrated embodiment, the ozone generating unit 2 may further include a first end cap 22 located at the first end and a second end cap 23 located at the second end.

[0063] like FIGS. 3A-4D As shown, the ozone generating unit 2 may further include an inlet pipe 260, an outlet pipe 270, an air inlet pipe 280, and an exhaust pipe 290 connected to the first end cap 22. The inlet pipe 260, outlet pipe 270, air inlet pipe 280, and exhaust pipe 290 define an inlet port 126, an outlet port 127, an air inlet port 128, and an air outlet port 129.

[0064] Continue to refer toFIG. 4A The invention describes a plurality of stacked plate ground electrodes 20 according to some embodiments of the invention. In the illustrated embodiments, the plate ground electrode 20 may include a single-piece or integral body. The body of the plate ground electrode 20 may be made of an aluminum alloy coated with a nano-ceramic material.

[0065] like FIG. 4C and FIG. 4A As shown, the ground electrode 20 may include a reaction region 2000 formed within at least one of a first surface 201 and a second surface 202 of the monolithic body 200, and a plurality of planar grooves 2010 extending laterally within the reaction region. In the illustrated embodiment, the reaction region 2000 is formed only on the first surface 201. In embodiments of the invention, the planar grooves 2010 may also be referred to as planar (micro)grooves, thereby allowing the planar grooves 2010 to form gas (micro)channels with extremely high aspect ratios together with the dielectric plate 216 of the high-voltage discharge assembly 21. In some preferred embodiments, the aspect ratio of the planar (micro)grooves 2010 is, for example, 10:1 to 200:1, more preferably 20:1 to 200:1, and even more preferably 50:1 to 150:1.

[0066] like FIG. 4C and FIG. 4A As shown, each planar groove 2010 includes a first curve located at the first end 2013 and a second curve located at the second end 2014. Specifically, the first curve 2015 can be a first parabolic curve 2015, and the second curve 2016 can be a second parabolic curve 2016.

[0067] like FIG. 4C and FIG. 4A As shown, the ground electrode 20 may further include an inlet micro-hole 2011 and an outlet micro-hole 2012 located within the envelope of each planar groove 2010. The inlet micro-hole 2011 is disposed near the first end 2013, and the outlet micro-hole 2012 is disposed near the second end 2014. FIG. 4C and FIGS. 2A-13C In the illustrated embodiment, the air inlet micro-orifice 2011 is generally located at the focal point of the first parabolic curve. More specifically, the center of the air inlet micro-orifice 2011 may approximately coincide with the focal point of the first parabolic curve. Similarly, the air outlet 2012 is generally located at the focal point of the second parabolic curve. More specifically, the center of the air outlet 2012 may approximately coincide with the focal point of the second parabolic curve.

[0068] In the embodiments of this application, the "micro-orifice" can be specifically determined according to the size of the ground electrode 20, for example, it can be less than or equal to 2 mm. In a preferred embodiment, the air inlet micro-orifice 2011 has a pore size of 0.1 mm to 1 mm, preferably 0.2 mm to 0.5 mm, and more preferably 0.2 mm to 0.3 mm.

[0069] In this embodiment, the thickness of the ground electrode can be determined based on the constraint of the micropores, thereby obtaining a thin ground electrode. Preferably, in FIG. 4A In the illustrated embodiment, the ratio of the thickness of the monolithic body of the ground electrode to the aperture of the air inlet micro-orifice is greater than or equal to 5 and less than or equal to 20, preferably greater than or equal to 6 and less than or equal to 16, more preferably greater than or equal to 8 and less than or equal to 15; preferably, the monolithic body has a thickness of 3 mm to 15 mm, preferably 3 mm to 10 mm, more preferably 4 mm to 6 mm. It will be understood that the intersection of both can be taken. In the illustrated preferred embodiment, the air inlet micro-orifice can have a thickness of 0.3 mm, and the ratio of the thickness of the monolithic body to the aperture of the air inlet micro-orifice can be 13.3.

[0070] As described herein, the exhaust port 2012 may not be limited to a "micro-orifice" and may have a wider range of aperture sizes. In a preferred embodiment, the aperture ratio of the exhaust port 2012 to the intake micro-orifice 2011 is in the range of 1.5 to 15, preferably in the range of 2 to 10, and more preferably in the range of 2 to 8.

[0071] like FIG. 4C and FIG. 4A As shown, the reaction zone 2000 is generally rectangular, and the one-piece body 200 of the ground electrode 20 can also form a reaction zone surrounding groove 2019 defining the reaction zone 2000 on the first surface 201. Thus, features on the first surface 201 located outside the reaction zone 2000 will be sealed and isolated from the reaction zone 2000.

[0072] like FIG. 4C and FIG. 4A As shown, the ground electrode 20 also includes a first pressure balancing structure. This first pressure balancing structure is in the form of a trench. Specifically, the ground electrode 20 includes a diversion trench 2018 located within the reaction zone 2000, symmetrically connected at its first end 2013 to one or more planar grooves 2010. For example... FIG. 4C and FIGS. 3A-5B As shown, the diversion groove 2018 connects the topmost planar groove 2010 and the bottommost planar groove 2010. (Refer to reference...) FIG. 4A The diversion trench 2018 extends beyond the envelope of the dielectric plate 216 of the high-voltage discharge assembly 21 to divert the reactive gas within the corresponding planar groove 2010 to the high-voltage discharge assembly 21, as further described below.

[0073] Continue to refer to FIG. 4C and FIGS. 4A-4D Preferably, all planar grooves 2010 are "almost" closed, except for the diversion grooves 2018.

[0074] The following section continues to describe other fluid flow structures of the ground electrode 20.

[0075] Continue to refer to FIG. 4B As shown, outside the reaction zone 2000, the ground electrode 20 also includes a plurality of through holes that serve as part of the fluid supply channel of the ozone generating unit 2. For example, these are a first air inlet through hole 282 that serves as part of the air inlet channel, a first exhaust through hole 292 that serves as part of the exhaust channel, a first inlet flow hole 262 that serves as part of the inlet flow channel, and a first exhaust flow hole 272 that serves as the exhaust flow channel.

[0076] like FIG. 4D and FIG. 4B As shown, the single-piece body 200 may also form a first air passage 2021 communicating with the air inlet micro-hole 2011, a second air passage 2022 communicating with the air outlet 2012, and a cooling passage 2020 on the second surface 202, all of which are open passages. Here, the cooling passage 2020 has a tortuous structure, for example, an M-shape.

[0077] Specifically, such as FIG. 4D and FIG. 4B As shown, the first air passage 2021 is orthogonal to the first air inlet hole 282, the second air passage 2022 is orthogonal to the first exhaust hole 292, one end of the cooling passage 2020 is orthogonal to the first air inlet hole 262, and the other end is orthogonal to the first exhaust hole 272. The air inlet micro-hole 2011 connects the first air passage 2021 and the corresponding planar groove 2010, and the exhaust hole 2012 connects the corresponding planar groove 2010 and the second air passage 2022.

[0078] like FIG. 4D and FIG. 4B As shown, the first air passage 2021 on the second surface 202 is connected to the inlet micro-orifice 2011 on the first surface 201 via a stepped hole structure 2026. The diameter of the stepped hole structure 2026 is larger than the diameter of the inlet micro-orifice 2011. Specifically, the stepped hole structure 2026 is a single-stage or multi-stage stepped hole, and the diameter of the single-stage stepped hole or the first stage diameter of the multi-stage stepped hole can be approximately equal to the diameter of the exhaust hole 2012. FIG. 4D and FIGS. 3A-4D In the embodiment shown, the stepped hole structure 2026 is a single-stage stepped hole.

[0079] Therefore, as FIG. 4A As shown, the first air inlet 282, the first air passage 2021, each air inlet micro-hole 2011, each planar groove 2010, each exhaust hole 2012, the second air passage 2022 and the first exhaust 292 form the airflow distribution structure in the ground electrode 20 in sequence.

[0080] like FIG. 4C and FIGS. 3A-4DAs shown, the ground electrode 20 forms, at the first surface 201, a surrounding groove around the first gas inlet through hole 282, a surrounding groove around the first gas outlet through hole 292, a surrounding groove around the first flow inlet through hole 262, and a surrounding groove around the first flow outlet through hole 272.

[0081] Similarly, as shown in FIG. 2B, the flow inlet through hole 262, the meandering cooling flow passage 2020, and the flow outlet through hole 272 form, in sequence, a cooling flow distribution structure in the ground electrode 20. FIG. 4B

[0082] As shown in FIG. 2B, the first gas path flow passage 2021 and the gas inlet through hole 282 form, in sequence, a first gas path surrounding groove 2024 in the second surface 202 of the single-piece body 200; the second gas path flow passage 2022 and the gas outlet through hole 293 form, in sequence, a second gas path surrounding groove 2025 in the second surface 202 of the single-piece body 200; and the flow inlet through hole 262, the cooling flow passage 2020, and the flow outlet through hole 272 form, in sequence, a cooling flow surrounding groove 2023 in the second surface 202 of the single-piece body 200. FIG. 4D FIG. 11 In combination with FIG. 12 FIGS. 2A-2C As shown in FIG. 2B, the second surface 202 of the single-piece body 200 further forms, in the second surface 202, the first gas path surrounding groove 2024 around the first gas path flow passage 2021 and the gas inlet through hole 282, the second gas path surrounding groove 2025 around the second gas path flow passage 2022 and the gas outlet through hole 293, and the cooling flow surrounding groove 2023 around the flow inlet through hole 262, the cooling flow passage 2020, and the flow outlet through hole 272. Accordingly, the first gas path surrounding groove 2024 can be fitted with a first gas path surrounding seal 204, the second gas path surrounding groove 2025 can be fitted with a second gas path surrounding seal 205, and the cooling flow surrounding groove 2023 can be fitted with a cooling flow surrounding seal 203.

[0083] In the illustrated embodiment, as shown in FIG. 2B, the ground electrode 20 can be fitted with the second surface 202 abutting so that the first gas path flow passages 2021 of the pair of ground electrodes 20 collectively form a circumferentially closed first gas flow space, the second gas path flow passages 2022 collectively form a circumferentially closed second gas flow space, and the cooling flow passages 2020 collectively form a circumferentially closed cooling flow space. As a result, the aligned first gas path surrounding grooves 2024 of the abutting pair of ground electrodes 20 can collectively accommodate the first gas path surrounding seal 204, the aligned second gas path surrounding grooves 2025 can collectively accommodate the second gas path surrounding seal 205, and the aligned cooling flow surrounding grooves 2023 can collectively accommodate the cooling flow surrounding seal 203. FIGS. 3A-3C As shown in FIG. 2B, the first gas path surrounding groove and the cooling flow surrounding groove have a common section; the second gas path surrounding groove and the cooling flow surrounding groove have a common section, preferably, the first gas path surrounding seal and the cooling flow surrounding seal have a slightly larger width in the common section and form a compression seal in the common section; the second gas path surrounding seal and the cooling flow surrounding seal have a slightly larger width in the common section and form a compression seal in the common section.

[0084]

[0085] ​​​​These seals can serve as alignment positioning structures for the ozone generating units when grouped, as further described below.

[0086] Furthermore, a number of first bolt holes 207 can be formed in the ground electrode 20.

[0087] The high voltage discharge assembly of the ozone generating unit 2 is described below with reference to FIGS. 5A-10B and FIGS. 2A-3C .

[0088] In the embodiment shown in FIGS. 3A-3C , the high voltage discharge assembly 21 is placed between the first surfaces of adjacent ground electrodes 20.

[0089] As shown in FIGS. 5A-10B and FIGS. 4C , the high voltage discharge assembly 21 can comprise a resilient frame member 210 and a pair of dielectric plates 216 on both sides. In addition, the high voltage discharge assembly 21 can further comprise a resilient pad assembly.

With reference to FIG. 5B and FIGS. 7A-9C and FIGS. 4CThe first pressure equalization groove 2103 extends beyond the envelope of the media plate 216 to communicate with the shunt groove 2018 outside the media plate to receive the reaction gas from the shunt groove 2018 of the ground electrode 20 and shunt to the pressure equalization zone 2100, which can be a hollow 2101 formed in the elastic frame member 210.

[0092] As shown, a number of lateral extending equalization channels are provided in the pressure equalization zone 2100. In the illustrated embodiment, the equalization channels are provided by the elastic pad assembly.

[0093] Referring to FIGS. 5A-5B , the elastic pad assembly includes an elastic pad 212 and a heat conducting plate 214 on both sides of the elastic pad.

The body 2140 of the heat conducting plate 214 is of a heat conducting metal material, such as stainless steel, and can be subjected to a suitable material treatment.

[0095] As shown FIGS. 4A-4D , the elastic pad assembly is floatingly mounted in the thickness direction such that the elastic pad assembly is spaced apart from the frame structure of the elastic frame member 210 to form a first gap G1 on a first side and a second gap G2 on an opposite second side of the pressure equalization zone 2100. In addition, gaps can also be formed at the top and bottom of the elastic pad assembly.

[0096] Referring to FIGS. 7A-8B , the elastic pad 212 includes a number of equalization grooves 2121, preferably two sets of equalization grooves 2121 on both sides of the elastic pad. The equalization grooves 2121 have open first and second ends. In this embodiment, the open first and second ends have end openings 2126, 2127. In this embodiment, the number of equalization grooves form a number of equalization channels with the corresponding heat conducting plates 214 for equalization of gas flow. In combination with reference to FIGS. 8A-9C and FIGS. 4A-4DThe number of the balance grooves 2121 of the elastic pad 212 corresponds to the number of the planar grooves 2010 of the ground electrode 20 for reacting the reaction gas, and at least some of the balance grooves have substantially the same shape as the corresponding planar grooves.

The dielectric plate 216 also includes an uncoated edge region 2163 that surrounds the conductor coating region 2161. The conductor coating region 2161 can be a silver coating region. With reference to FIG. 10B and FIGS. 5A-6D and FIGS. 5A-6D The uncoated edge region 2163 is configured such that the conductor coating region 2161 is spaced apart from the frame structure of the frame member 210, and the heat conducting plate 214 of the elastic pad assembly substantially covers the conductor coating region 2161, thereby forming an electrical discharge along the surface suppression structure.

[0099] In addition, as previously described, the elastic pad assembly and the frame structure of the frame member 210 form a gap G1, G2, etc., and thereby the gap forms a further electrical discharge along the surface suppression structure.

These sealing ridges can engage corresponding surrounding grooves of the ground electrode 20 that engage adjacent ground electrodes.

[0101] The sealing ridges can also serve as alignment positioning structures for the ground electrode 20 and the high-voltage discharge assembly 21.

[0102] With continued reference to FIGS. 5A-6D and FIGS. 13A-13B , the high-voltage discharge assembly 21 further comprises pad holes 2117, 2118 in the elastic frame member 210 and rigid pads 217, 218 for being received in the pad holes.

[0105] The mounting (grouping) of the ozone generation unit 2 according to the first embodiment of the present application and the corresponding alignment and sealing will be described below with reference to FIG. 3B

[0106] In the assembled ozone generation unit 2, the ground electrodes 20 are arranged in pairs, wherein the pairs of ground electrodes 20 are attached to the second surface 202 and adjacent pairs of ground electrodes 20 are arranged opposite to each other on the first surface 201 and sandwich a high-voltage discharge assembly 21, thereby forming a discharge chamber between the first surfaces 201 of the opposite ground electrodes 20 (and the high-voltage discharge assembly 21). As shown in FIG. 4B As best shown, the elastic frame member 210 (frame structure) of the high-voltage discharge assembly 21 also constitutes part of the thickness of the ozone generation unit 2.

[0107] ​The assembly of the ozone generation unit 2 is continued as follows. First, the second end cover 23 can be placed on a flat surface, and the electrodes 20 and high-voltage discharge assemblies 21 are stacked in the manner described above (e.g., two electrodes 20 are stacked, followed by one high-voltage discharge assembly 21, and so on, except for the end electrodes 20). At this time, the abutting electrodes 20 and the adjacent high-voltage discharge assemblies 21 are pre-aligned by means of the alignment positioning structures, including but not limited to the first gas channeling seal 204 received in the first gas channeling groove 2024 of the abutting electrodes 20, the second gas channeling seal 205 received in the second gas channeling groove 2025 of the abutting electrodes 20, and the cooling flow channeling seal 203 received in the cooling flow channeling groove 2023 of the pair of abutting electrodes 20, and the sealing ribs 2113 surrounding the second gas inlet through hole 283, the sealing ribs 2114 surrounding the second gas outlet through hole 293, the sealing ribs 2115 surrounding the second flow inlet through hole 263, and the sealing ribs 2116 surrounding the second flow outlet through hole 273. As shown in FIG. 2C and FIG. 2A The alignment positioning structures on the second surface 202 occupy at least 60%, preferably 70%-90% of the lateral dimension and at least 60%, preferably 70%-90% of the vertical dimension of the single-piece body 200.

[0108] When the stacking of the electrodes 20 and high-voltage discharge assemblies 21 is completed, the first end cover 22 can be pressed against the upper end, so that the alignment positioning structures described above are precisely self-aligned due to the pressing. As shown in FIG. 3C The pressing of the first end cover 22 is preferably achieved by gravity, e.g., the weight (or thickness) of the first end cover 22 is more than 2 times, preferably more than 5 times, the weight (or thickness) of the electrodes 20. It will be appreciated that the first end cover 22 and the second end cover 23 are merely distinguished from each other, and are not limited to the use of a specific end cover for pressing.

[0109] Subsequently, bolts can be screwed into the bolt through holes 221 of the second end cover 23, so that the bolts pass through the first end cover 22, the electrodes 20 and the high-voltage discharge assemblies 21, and are screwed into the bolt through holes 221 of the second end cover 23.

[0110] Through the above assembly process, the various components of the ozone generation unit 2 can be precisely aligned and sealed, thereby ensuring the performance and stability of the device.

[0111] The fluid supply (discharge) of the assembled ozone generator and the fluid distribution in the electrodes will be described below.

[0112] With reference to FIGS. 14-23 and FIG. 14Similarly, the first gas inlet holes of each ground electrode and the second gas inlet holes of each high-voltage discharge assembly of the installed ozone generation unit are aligned along the stacking direction to form a gas inlet passage across each ground electrode, and the gas inlet passage is configured to be axially aligned with a gas inlet tube for the ozone generation unit. Similarly, the first gas outlet holes of each ground electrode and the second gas outlet holes of each high-voltage discharge assembly of the installed ozone generation unit are aligned along the stacking direction to form a gas outlet passage across each ground electrode, and the gas outlet passage is configured to be axially aligned with a gas outlet tube for the ozone generation unit.

[0113] Here, the reaction gas will enter the gas inlet passage from the gas inlet tube, then flow into the first gas path flow channel of each ground electrode (the pair of abutting ground electrodes) across, pass through the gas inlet micro-holes, and then enter the planar recess for reaction, and the generated gas will flow from the gas outlet hole to the second gas path flow channel, then flow into the gas outlet passage, and then enter the gas outlet tube. In this way, the gas supply (discharge) structure will not be directly connected to the planar recess.

[0114] Similarly, the cooling fluid will enter the flow inlet passage from the flow inlet tube, then flow into the M-shaped cooling flow channel of each ground electrode (the pair of abutting ground electrodes) across, and then flow to the flow outlet passage, and then enter the flow outlet tube. In this way, the cooling fluid branch pipe will be saved, and the cooling fluid supply and discharge are provided by the flow inlet and flow outlet passages incorporated into the ozone generation unit.

[0191] Unlike the first or second embodiment, the elastic frame member in the third embodiment does not constitute a part of the thickness of the ozone generating unit, i.e. the relevant part of the thickness is constituted by the ground electrode, whereby the high voltage discharge assembly can be accommodated in the recessed reaction zone. Correspondingly, unlike the first or second embodiment, the third embodiment does not have a spacer block.

[0192] The elastic frame member of the high voltage discharge assembly can further comprise a second bolt through hole (not shown).

[0193] As shown in Fig. 2, the elastic frame member 210 of the high voltage discharge assembly 21 can further have a protrusion 2119 which can be accommodated in the recessed reaction zone 2019 to provide a seal. Figure 24 As shown in Fig. 2, the elastic frame member 210 of the high voltage discharge assembly 21 can further have a protrusion 2119 which can be accommodated in the recessed reaction zone 2019 to provide a seal. Figures 26A-29B As shown in Fig. 2, the elastic frame member 210 of the high voltage discharge assembly 21 can further have a protrusion 2119 which can be accommodated in the recessed reaction zone 2019 to provide a seal.

[0194] Unlike the first or second embodiment, the ground electrode and the high voltage discharge assembly in the third embodiment are mounted alternately, the mounting method of which can be performed according to the conventional stacking, and can be tightened by a bolt tightening mechanism.

[0195] Similarly to the first or second embodiment, in the third embodiment, as shown in Fig. 2, the first gas inlet through holes of each ground electrode and the second gas inlet through holes of each high voltage discharge assembly of the installed ozone generating unit 2 are aligned in the stacking direction to form a gas inlet passage across each ground electrode, and the gas inlet passage is configured to be axially aligned with a gas inlet pipe for the ozone generating unit. Similarly, the first gas outlet through holes of each ground electrode and the second gas outlet through holes of each high voltage discharge assembly of the installed ozone generating unit are aligned in the stacking direction to form a gas outlet passage across each ground electrode, and the gas outlet passage is configured to be axially aligned with a gas outlet pipe for the ozone generating unit. Similarly, the first flow inlet through holes of each ground electrode and the second flow inlet through holes of each high voltage discharge assembly of the installed ozone generating unit are aligned in the stacking direction to form a flow inlet passage across each ground electrode, and the flow inlet passage is configured to be axially aligned with a flow inlet pipe for the ozone generating unit. Similarly, the first flow outlet through holes of each ground electrode and the second flow outlet through holes of each high voltage discharge assembly of the installed ozone generating unit are aligned in the stacking direction to form a flow outlet passage across each ground electrode, and the flow outlet passage is configured to be axially aligned with a flow outlet pipe for the ozone generating unit. Figure 24 Here, the reaction gas will enter the gas inlet passage from the gas inlet pipe, then flow into the first gas path flow channel of each ground electrode across, pass through the gas inlet micro hole and then enter the planar recess for reaction, and the generated gas will flow from the gas outlet hole to the second gas path flow channel, then flow into the gas outlet passage and then enter the gas outlet pipe. Thus, the gas supply (discharge) structure will not directly communicate with the planar recess.

[0196]

[0197] ​Similarly, the cooling fluid will enter the inlet flow channel from the inlet flow tube, then flow into the parallel cooling flow channels of each of the transverse ground electrodes, and then flow to the outlet flow channel before exiting the outlet flow tube. Thus, the cooling fluid branch tubes will be eliminated, and the cooling fluid supply and discharge will be provided by the inlet and outlet flow channels incorporated into the ozone generation unit.

[0198] With reference to the drawings Figures 30-33B An ozone generation unit 2"' according to a fourth embodiment of the present application is described with reference to the drawings.

[0200] The ozone generation unit 2"' can also include high-voltage discharge assemblies 21"' disposed between the ground electrodes.

[0201] Correspondingly, the ground electrodes 20"' and the high-voltage discharge assemblies 21"' (as well as the end ground electrodes, the adjacent ground electrodes, and the high-voltage discharge assemblies therebetween) can collectively form a discharge chamber for the discharge reaction. However, unlike the first and second embodiments, in this fourth embodiment the ozone generation unit 2"' is configured such that each ground electrode 20"', 22"', or 23"' is arranged alternately with each high-voltage discharge assembly 21"', i.e., not as a ground electrode pair.

[0202] The ozone generation unit 2"' can also include an inlet flow tube 261"', an outlet flow tube 271"', an inlet gas tube 281"', and an outlet gas tube 291"' connected to the first end cap 22"'.

Specifically, the first curve can be a first parabolic curve 2015''', and the second curve can be a second parabolic curve 2016'''. Similarly, the ground electrode 20''' can also include an air inlet micro-hole 2011''' and an air outlet hole 2012''' within the envelope of each planar groove 2010''', the air inlet micro-hole 2011''' being disposed adjacent to the first end 2013''', and the air outlet hole 2012''' being disposed adjacent to the second end 2014'''. The air inlet micro-hole 2011''' is disposed substantially at the focal point of the first parabolic curve. More specifically, the center of the air inlet micro-hole 2011''' can substantially coincide with the focal point of the first parabolic curve. Similarly, the air outlet hole 2012''' is disposed substantially at the focal point of the second parabolic curve. More specifically, the center of the air outlet hole 2012''' can substantially coincide with the focal point of the second parabolic curve.

More specifically, the center of the air outlet hole 2022''' can substantially coincide with the focal point of the second parabolic curve.

[0206] The structure and size of the air inlet micro-hole and the air inlet hole of the fourth embodiment can refer to the first or second embodiment, but the air inlet micro-hole and the air inlet hole of the ground electrode 20''' of the fourth embodiment are disposed in both surfaces.

[0207] Unlike the first to third embodiments, the suboptimal embodiment shown in the fourth embodiment is not a thin ground electrode obtained based on the constraint of the micro-hole, but a ground electrode of a regular thickness. However, it is conceivable that other features of this embodiment can be combined with other embodiments in a non-contradictory manner, or this embodiment can be modified into a thin ground electrode.

[0208] Combination reference Figures 30-33BThe reaction zone 2000" is substantially rectangular, and the single-piece body 200" of the ground electrode 20" further comprises a reaction zone-encircling groove 2019", 2029" formed in both the first surface 201" and the second surface 202".

[0209] With reference to Figures 30-33B The ground electrode 20" further comprises a first pressure balancing structure. The first pressure balancing structure is in the form of a groove. In the illustrated embodiment, the first pressure balancing structure is formed in the first surface only, but it is contemplated that it could be formed in the reverse or in both surfaces. In particular, the ground electrode 20" comprises a shunt groove 2018" within the reaction zone 2000 that symmetrically connects a planar recess 2010" (intermediate planar recess) at the first end 2013. The shunt groove 2018" extends to and only to the gas inlet micro-holes 2011" in the planar recess.

[0210] With reference to Figure 24 and Figures 26A-26F Preferably, all of the planar recesses 2010" in the first surface are almost closed, e.g., except for the shunt groove 2018"; and preferably, all of the planar recesses 2020" in the second surface are closed.

[0211] Further fluid flow structures of the ground electrode 20" are described below.

[0212] With reference to Figures 30-33B Outside of the reaction zone 2000", the ground electrode 20" further comprises a plurality of through-holes that function as part of the fluid supply channels of the ozone generation unit 2", e.g., in this case, first gas inlet through-holes 282" that are part of the gas inlet channel, second gas outlet through-holes 292" that are part of the gas outlet channel, first flow inlet through-holes 262" that are part of the flow inlet channel, and first flow outlet through-holes 272" that are part of the flow outlet channel.

[0213] Similar to the third embodiment, with reference to Figures 30-33B The ground electrode 20" can further comprise a first gas path flow channel 205" formed inside the single-piece body 200" that is a vertical flow channel intersecting the first gas inlet through-holes. The ground electrode 20" can further comprise a second gas path flow channel 206" formed inside the single-piece body 200" that is a vertical flow channel intersecting the first gas outlet through-holes. The ground electrode 20" can further comprise a cooling flow channel 204" formed inside the single-piece body 200" that comprises a plurality of parallel vertical flow channels formed inside the single-piece body and a horizontal communication structure 2042" at the top and bottom that communicates the vertical flow channels, a first vertical flow channel of the plurality of parallel vertical flow channels intersecting the first flow inlet through-holes and a second vertical flow channel of the plurality of parallel vertical flow channels intersecting the first flow outlet through-holes.

[0214] However, unlike the third embodiment, the reference to Figures 30-33B The communication structure shown in the fourth embodiment is located on the surface (e.g., the first surface) of the single-piece body, whereby the flow channel in the fourth embodiment can be conventionally sealed with a screw.

[0215] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and associated alignment positioning structure described in the first or second embodiments can not be provided in the fourth embodiment.

[0216] In addition, a number of first bolt holes 207"'can be formed in the ground electrode 20" '.

[0217] The first end cap (end ground electrode) 22"'can be formed similarly to the ground electrode 20" ', but with the difference that the first surface 221"'of the ground electrode 22"'is not provided with a reaction zone and associated features.

[0218] With reference to Figures 30-33B The first end cap 22"'can include a reaction zone 2200"'formed in the second surface 222"'of the single-piece body 220" '. The ground electrode 22"'can include a plurality of planar grooves 2220"'extending laterally in the reaction zone.

[0219] Each planar groove 2220"'on the second surface 222"'includes a first curve at a first end 2223"'and a second curve at a second end 2224" '. In particular, the first curve can be a first parabolic curve 2225"'and the second curve can be a second parabolic curve 2226" '. Similarly, the first end cap 22"'can also include an inlet micro-hole 2221"'and an outlet hole 2222"'located within the envelope of each planar groove 2220" ', the inlet micro-hole 2221"'being located proximate to the first end 2223"'and the outlet hole 2222"'being located proximate to the second end 2224" '. The inlet micro-hole 2221"'is located substantially at the focal point of the first parabolic curve. More particularly, the center of the inlet micro-hole 2521"'can substantially coincide with the focal point of the first parabolic curve. Similarly, the outlet hole 2222"'is located substantially at the focal point of the second parabolic curve. More particularly, the center of the outlet hole 2222"'can substantially coincide with the focal point of the second parabolic curve.

[0220] The structure and size of the inlet micro-hole and the inlet hole of the first end cap 22"'can refer to the ground electrode 20" ', but the inlet micro-hole and the inlet hole of the first end cap 22"'of the fourth embodiment are located in the second surface.

[0221] With reference to Figures 30-33BThe reaction zone 2200" is substantially rectangular, and the single-piece body 220" of the first end cap 22" further defines a reaction zone surrounding groove 2229" in the second surface 222" that defines the reaction zone 2200".

[0222] With reference to Figures 30-33B Like the ground electrode 20", the first end cap 22" further includes a first pressure balancing structure. The first pressure balancing structure is in the form of a groove. Specifically, the first end cap 22" includes a shunt groove 2218" in the reaction zone 2200 that symmetrically connects a planar recess 2210" (intermediate planar recess) at the first end 2213". The shunt groove 2218" extends to and only to a gas inlet micro-hole 2211" in the planar recess.

[0223] With reference to Figures 30-33B Preferably, all of the planar recesses 2520" in the second surface are closed except for the shunt groove 2218" described above.

[0224] Other fluid flow structures of the first end cap 22" are described below.

[0225] With reference to Figures 30-33B Outside of the reaction zone 2200", the ground electrode 22" and the first end cap 22" further include a plurality of through-holes that serve as part of the fluid supply channels of the ozone generation unit 2", here, for example, a first gas inlet through-hole 282" that is part of the gas inlet channel, a second gas outlet through-hole 292" that is part of the gas outlet channel, a first flow inlet through-hole 262" that is part of the flow inlet channel, and a first flow outlet through-hole 272" that is part of the flow outlet channel.

[0226] Like the third embodiment, the first end cap 22" can further include a first gas path flow channel 225" formed inside the single-piece body 220" that is a vertical flow channel intersecting the first gas inlet through-hole. The first end cap 22" can further include a second gas path flow channel 226" formed inside the single-piece body 220" that is a vertical flow channel intersecting the first gas outlet through-hole. The first end cap 22" can further include a cooling flow channel 224" formed inside the single-piece body 220" that includes a plurality of parallel vertical flow channels formed inside the single-piece body and a horizontal communication structure 2242" at the top and bottom that communicates the vertical flow channels, a first vertical flow channel of the plurality of parallel vertical flow channels intersecting the first flow inlet through-hole and a second vertical flow channel intersecting the first flow outlet through-hole.

[0227] Like the ground electrode 20", with reference to Figures 30-33B The communication structure shown in the fourth embodiment is located on a surface of the single-piece body (e.g., the first surface), whereby the flow channels in the fourth embodiment can be conventionally sealed with screws.

[0228] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and the associated alignment positioning structure as described in the first or second embodiment can not be provided in the fourth embodiment.

[0229] Furthermore, a number of first bolt holes 227"'can also be formed in the first end cap 22" '.

[0230] Unlike the first or second embodiment, in the fourth embodiment, the through hole for fluid supply (discharge) is circular.

[0231] Furthermore, it will be appreciated that, although the ground electrode of one end portion is described above, the ground electrode of the other end portion which is symmetrically opposite can be envisaged.

[0232] The high-voltage discharge assembly 21"'of the ozone generation unit 2"'of the fourth embodiment is described below with reference to Figures 30-33B

[0233] As shown in Figures 30-33B , the high-voltage discharge assembly 21"'can include a resilient frame member 210"'and a pair of dielectric plates 216"'on two sides. Furthermore, the high-voltage discharge assembly 21"'can also include a resilient pad assembly.

[0234] The resilient frame member 210"'includes a joint portion, a terminal held by the joint portion and extending out from the top of the joint portion, and a pair of resilient contact pieces electrically connecting the terminal, the pair of resilient contact pieces electrically contacting the back side of the pair of dielectric plates 216" '. The joint portion can be accommodated in a limiting recess.

[0235] The resilient frame member 210"'can have a frame structure defining a pressure balancing region at the back side of the pair of dielectric plates 216" '. Similar to the third embodiment, the resilient frame member also includes a second pressure balancing structure including a pressure balancing groove having an opening. The pressure balancing groove extends beyond the envelope of the dielectric plates 216"'so as to communicate with the shunt groove outside the dielectric plates to receive the reaction gas from the shunt groove of the ground electrode and shunt to the pressure balancing region, which can be a hollow formed in the resilient frame member. A number of laterally extending balancing channels will be provided in the pressure balancing region, which are provided by the resilient pad assembly.

[0236] As shown in Figures 30-33B ​As shown, the elastic pad assembly includes an elastic pad 212”' and heat-conducting plates 214”' located on both sides of the elastic pad. The heat-conducting plates 214”' are preferably bonded to the elastic pad 212”'. The elastic pad assembly 212”' is floatingly mounted in the thickness direction within the pressure balance zone of the elastic frame member 210”'. Specifically, the elastic frame member 210”' includes a plurality of positioning bosses (not shown). The elastic pad assembly 212”' includes a plurality of positioning notches (not shown) for mounting to the plurality of positioning bosses.

[0237] The elastic pad assembly is floatingly mounted in the thickness direction, such that the elastic pad assembly is spaced apart from the frame structure of the elastic frame member 210”', to form a first gap on the first side of the pressure balance zone 2100”' and a second gap on the opposite second side. In addition, gaps may also be formed at the top and bottom of the elastic pad assembly.

[0238] like Figures 30-33B As shown, the elastic pad 212”' includes a plurality of balancing grooves, preferably two sets of balancing grooves located on both sides of the elastic pad. The balancing grooves have an open first end and a second end. In this embodiment, the open first end and the second end have beveled surfaces. In this embodiment, the plurality of balancing grooves, together with the corresponding heat-conducting plate 214”', form a plurality of balancing channels for balancing gas flow. The number of the plurality of balancing grooves of the elastic pad 212”' corresponds to the number of planar grooves for the reaction gas of the ground electrodes 20”' and 22”', and at least some of the balancing grooves have a shape substantially the same as the corresponding planar grooves.

[0239] like Figures 30-33B As shown, the elastic pad assembly may also have a notch to allow for the elastic contact piece. The shape of the balancing groove, except for the notch, is substantially the same as the shape of the corresponding planar groove.

[0240] like Figures 30-33B As shown, there are connecting channels 2128”' between several balancing grooves 2121”' and elastic protrusions 2122”', and there are gap regions 2123”' between the elastic protrusions.

[0241] Similar to the first, second, and third embodiments, the dielectric plate 216”' has a surface discharge suppression structure. Furthermore, as previously described, the elastic pad assembly forms a gap with the frame structure of the frame member 210”', thereby creating a further surface discharge suppression structure.

[0242] As Figure 1F As shown, the elastic frame 210"' of the high-voltage discharge assembly 21"' may include a second inlet port, a second outlet port, a second inlet flow port, and a second outlet flow port located outside the dielectric plate 216"', which are formed by sealing rings. These sealing rings can engage the corresponding surrounding grooves of adjacent ground electrodes of the ground electrode.

[0243] Similarly to the third embodiment, the elastic frame member in the fourth embodiment does not constitute a part of the thickness of the ozone generating unit, i.e. the relevant part of the thickness is constituted by the ground electrode, whereby the high voltage discharge assembly can be accommodated in the recessed reaction zone. Correspondingly, in contrast to the first or second embodiment, the fourth embodiment does not have a spacer.

[0244] The elastic frame member of the high voltage discharge assembly can further comprise a second bolt through hole (not shown).

[0245] The elastic frame member 210" of the high voltage discharge assembly 21"' of the fourth embodiment can further have a surrounding ridge, which can be accommodated in the surrounding groove of the reaction zone to provide a seal.

[0246] Similarly to the third embodiment, the ground electrode and the high voltage discharge assembly of the fourth embodiment are mounted alternately, which can be done according to the conventional stacking and can be tightened by the bolt tightening mechanism 24"'.

[0247] The fluid supply (discharge) structure and the distribution structure of the fourth embodiment are similar to those of the third embodiment and will not be described here again.

[0248] As mentioned before, especially with reference to Figure 1G and Figures 1A-33B The plate-type ozone generating unit 2 of the ozone generator 10 can be connected to the electrical elements by means of a wiring strip (or wiring terminal).

[0249] As mentioned before, the ozone generating unit 2 can comprise a plurality of stacked ground electrodes, one or more high voltage discharge assemblies arranged between the plurality of stacked ground electrodes. Correspondingly, the one or more high voltage discharge assemblies can be electrically connected to the high voltage wiring strip 3 (or high voltage wiring terminal), and the ground electrodes can be electrically connected to the second bus bar 31, 31" (or second wiring terminal). Not shown in the figures, the high voltage wiring strip 3 (or high voltage wiring terminal) can comprise or be connected to one or more parallel arranged high voltage fuse devices electrically connected to the plurality of high voltage discharge devices. The electrical connections mentioned above can be realized, for example, by means of plug-in connectors (not shown).

[0250] The high voltage fuse device comprised by the ozone generator, e.g. ozone generating unit, according to the embodiments of the present application can be a high voltage fuse device dedicated for ozone generators or generating units.

[0251] Correspondingly, the second bus bar 31 can be connected to the wiring ground terminal, e.g. by means of a screw to the ground electrode 20.

[0252] The specific structure of the high voltage wiring strip, the high voltage fuse device, the second bus bar, etc. will not be described here again, as it is not essential.

[0275] The first group of embodiments relates to Figures 1A-33B , and relates to a novel ground electrode structure.

[0276] In some techniques known to the inventor, it is proposed to realize the generation of ozone gas by a planar groove as the reaction space.

[0277] In further techniques known to the inventor based on planar grooves, it is "desired" to provide as large a flow of reaction gas as possible in the planar micro-groove to provide more reaction gas to the planar micro-groove and to provide a higher flow of generated gas, for which an open end is formed at both ends of the planar groove, and a long hole or long groove is formed in the recessed area to form a long gas cavity in the recessed area of the stacked ground electrodes.

[0278] In another technique known to the inventor based on planar grooves, gas inlet and outlet holes are formed in the planar grooves of the pair of ground electrodes, which pass through the ground electrodes. And based on the "desire" to improve the flow of reaction gas, in this technique a plurality of gas inlet and outlet through-holes are used which pass through the body of the ground electrode, and a further recessed seat is formed from the planar groove at the position of the gas inlet and outlet through-holes as a smooth diffusion structure.

[0279] However, the inventor found that in the embodiment 1.1 of the invention, by significantly reducing the size of the gas inlet hole connected to the planar groove to a gas inlet micro-hole (the size of the gas outlet hole can have a higher margin) and allowing the gas inlet micro-hole to be adjacent to the curved end, the ozone reaction efficiency can be significantly improved, so that the ozone generation unit has a significantly higher yield per unit volume (unit weight). Compared with the two aforementioned techniques based on planar grooves, the gas inlet micro-hole and the structure of the curved end combined with it in the embodiment of the invention intentionally reduces the size of the flow inlet, to some extent against the intuition of expanding the flow inlet as much as possible to improve the flow of reaction gas and thus improve the gas production efficiency; and also saves the specially arranged diffusion structure, achieving unexpected results. Accordingly, the embodiment 1.1 of the invention further improves the gas production efficiency by combining the curved end structure with the gas outlet hole, but the inventor realizes that the design of the gas outlet hole size can have a higher margin (as described in embodiment 1.5), rather than necessarily reducing it to a micro-hole.

[0280] Further, more surprisingly, it is found that embodiments 1.2 and 1.3 of the invention can more optimally improve the gas production efficiency by providing smooth gas flow along the curve by setting the gas inlet micro-hole (and preferably also the gas outlet hole) at the focal point of the parabolic curve, especially coinciding with the focal point.

[0281] Further, embodiments 1.4 and 1.5 of the invention can further improve the reaction gas flow distribution effect by making part or almost all of the curved end form a closed end, thereby further improving the gas production efficiency.

[0282] Furthermore, the gas inlet micro-holes (and gas outlet holes) of the embodiments of the present application in combination with the curved end structure allow the reaction zone to be formed without being a recessed zone or in a recessed zone, which allows the compact structure of the ozone generation unit and its discharge chamber to be achieved, and also allows the thin ground electrode to be possible, such as the thin ground electrode described in the 8th group of embodiments.

[0283] Furthermore, the gas inlet micro-holes of the embodiments of the present application also allow the ground electrode itself to form an efficient and compact reaction gas distribution structure and cold zone fluid distribution structure and associated structures (as described in embodiments 1.9 to 1.14), and also allow advantageous applications to be formed by the gas inlet micro-holes in combination with these structures, such as novel fluid distribution structures and related sealing, positioning structures.

[0284] Furthermore, the gas inlet micro-hole structure of the embodiments of the present application allows novel discharge chamber related components, structures or parts to be possible, such as novel ground electrodes, high-voltage discharge components and related pressure balance structures, heat balance structures, surface discharge suppression structures, etc.
