[0047] In one aspect, combining Figures 1 to 7 As shown, an embodiment of the present disclosure provides a cooling device for an ozone generator, and the cooling device for an ozone generator includes a plurality of cooling plates 1, a main water inlet pipe 2 and a main water outlet pipe 3.

[0048] Combination Figure 1 As shown, several cooling plates 1 are arranged side by side, and several cooling plates 1 are arranged at equal intervals. A spiral water flow channel is formed in each cooling plate 1, and the water flow channel is used to pass cooling water to cool the cooling plate 1. A water inlet 11 and a water outlet 12 are formed at both ends of the bottom of the cooling plate 1, respectively. The water inlet 11 is connected to the water inlet end of the water flow channel, and the water outlet 12 is connected to the water outlet end of the water flow channel;

[0049] In this way, the water inlet 11, the water flow channel and the water outlet 12 inside the cooling plate 1 are connected in sequence.

[0050] The ozone generator includes a plurality of discharge units, each of which includes a high-voltage electrode plate, a dielectric plate, a cooling plate 1, a grounding electrode plate and a gasket, wherein the dielectric plate, the gasket and the grounding electrode plate are superimposed in sequence and symmetrically distributed about the high-voltage electrode plate, the high-voltage electrode plate is used for externally connecting a high-frequency high-voltage power supply, the cooling plate 1 is used for cooling the grounding electrode plate and the dielectric plate, and a dielectric barrier discharge air gap is formed between the grounding electrode plate, the gasket and the dielectric plate.

[0051] Specifically, when the discharge air gap is controlled within a certain range, the narrower the discharge air gap is, the more helpful it is to increase the gas discharge density, thereby increasing the yield of ozone.

[0052] Dielectric barrier discharge is usually driven by a sinusoidal AC high voltage power supply. As the supply voltage increases, the state of the reaction gas in the system will undergo three stages of change, from insulation to discharge and finally breakdown.

[0053] Specifically, the cooling plate 1 is a square plate structure, and mounting holes 17 are formed at the corners of the cooling plate 1. The mounting holes 17 are used for screws to pass through, so as to assemble the discharge units of the ozone generators together.

[0054] Of course, the formation of the cooling plate 1 includes but is not limited to a square plate structure, for example, it can also be other types of structures such as a rectangle or a circle.

[0055] In addition, the water flow channel is not limited to cooling water, and other types of coolants are also possible.

A plurality of drain ports 21 are arranged side by side on the upper end of the pipe wall of the main water inlet pipe 2. The drain ports 21 correspond to the water inlet ports 11 one by one, and the drain ports 21 are connected to the water inlet ports 11.

[0057] The main water outlet pipe 3 is a tubular structure with one end closed. A plurality of water inlets 31 are arranged side by side at the upper end of the pipe wall of the main water outlet pipe 3 . The water inlets 31 correspond to the water outlets 12 one by one, and the water inlets 31 are connected to the water outlets 12 .

[0058] Specifically, by providing a plurality of cooling plates 1, a main water inlet pipe 2 and a main water outlet pipe 3, the plurality of cooling plates 1 are arranged side by side, a water flow channel is formed in the cooling plate 1, the water flow channel is spiral-shaped, and has a small resistance to water, which can ensure the rapid flow of water, achieve a good cooling effect of the cooling plate 1, and is conducive to improving the efficiency of ozone generation and ensuring the purity of ozone;

[0059] The main water inlet pipe 2 and the main water outlet pipe 3 are both tubular structures with one end closed. Drain ports 21 are arranged side by side on the pipe wall of the main water inlet pipe 2, and the drain ports 21 are connected to the water inlet 11 on the cooling plate 1. Water inlets 31 are arranged side by side on the pipe wall of the main water outlet pipe 3, and the water inlet 31 is connected to the water outlet 12 on the cooling plate 1. The main water inlet pipe 2 transports water to the cooling plate 1 through each drain port 21, and the water flow after heat exchange is discharged from the main water outlet pipe 3, thereby realizing synchronous cooling of each cooling plate 1, thereby effectively cooling the ozone generator.

[0060] In some embodiments of the present application, the distance between two adjacent drain ports 21 , the distance between two adjacent water inlets 31 , the distance between two adjacent water inlets 11 , and the distance between two adjacent water outlets 12 are all equal.

[0061] In this way, the cooling plate 1, the water inlet branch pipe 4, and the water outlet branch pipe 5 are arranged at precise intervals, which facilitates the assembly of the cooling device for the ozone generator and improves the structural regularity.

[0062] In some embodiments of the present application, the cooling device for the ozone generator further includes a water inlet branch pipe 4 and a water outlet branch pipe 5 .

[0063] One end of the water inlet branch pipe 4 is connected to the cooling plate 1 through the water inlet 11, and the other end of the water inlet branch pipe 4 is connected to the main water inlet pipe 2 through the drain port 21; and / or,

[0064] One end of the water outlet branch pipe 5 is connected to the cooling plate 1 through the water outlet 12 , and the other end of the water outlet branch pipe 5 is connected to the main water outlet pipe 3 through the water inlet 31 .

[0065] Specifically, by providing the water inlet branch pipe 4 and the water outlet branch pipe 5 , it is convenient to connect the cooling plate 1 with the main water inlet pipe 2 and the main water outlet pipe 3 .

[0066] In some embodiments of the present application, the cooling plate 1, the main water inlet pipe 2, the main water outlet pipe 3, the water inlet branch pipe 4 and the water outlet branch pipe 5 are all made of metal materials.

[0067] Exemplarily, the cooling plate 1, the main water inlet pipe 2, the main water outlet pipe 3, the water inlet branch pipe 4 and the water outlet branch pipe 5 are all made of stainless steel or metal aluminum.

[0068] Stainless steel has good corrosion resistance and can withstand the corrosion of ozone; in addition, stainless steel has high hardness and mechanical strength. Stainless steel can be food grade 316L stainless steel.

[0069] In some embodiments of the present application, the water inlet branch pipe 4 and the main water inlet pipe 2 and the cooling plate 1, as well as the water outlet branch pipe 5 and the main water outlet pipe 3 and the cooling plate 1 are sealed and connected by welding.

[0070] Specifically, by sealing the water inlet branch pipe 4 with the main water inlet pipe 2 and the cooling plate 1, as well as the water outlet branch pipe 5 with the main water outlet pipe 3 and the cooling plate 1 by welding, the occurrence of water leakage at the connection can be reduced, and the stable and reliable operation of the ozone generator can be better ensured.

[0071] For example, the water inlet branch pipe 4 and the main water inlet pipe 2 and the cooling plate 1, as well as the water outlet branch pipe 5 and the main water outlet pipe 3 and the cooling plate 1 are sealed and welded together by vacuum brazing, and the overall appearance is good.

[0072] Of course, other types of welding methods are also within the protection scope of this application as long as they can ensure a sealed connection effect.

[0073] Combination Figure 3 and Figure 4 As shown, in some embodiments of the present application, a groove body 22 is formed at a position on the main water inlet pipe 2 corresponding to the drain outlet 21, and at a position on the main water outlet pipe 3 corresponding to the water inlet 31, and the groove body 22 is configured to hold an appropriate amount of solder paste.

[0074] Specifically, a groove body 22 is formed at a position corresponding to the drain outlet 21 on the main water inlet pipe 2 and at a position corresponding to the water inlet 31 on the main water outlet pipe 3. The groove body 22 can be used to hold and fix the solder paste in a certain area to avoid the occurrence of welding failure caused by overflow of the solder paste after high-temperature melting during welding. At the same time, it is beneficial to maintain the aesthetics of the welding point.

[0075] Of course, if the welding is performed by vacuum brazing, the solder paste used is brazing paste.

[0076] In some embodiments of the present application, Figure 3 and Figure 5 As shown, the cooling plate 1 includes a main body 13 and a cover plate 14 .

[0077] The main body 13 is a plate-like structure, a positioning groove 131 is formed on one side surface of the main body 13, a spiral water flow groove 132 is formed in the positioning groove 131, and a water inlet 11 and a water outlet 12 are formed at the bottom of the main body 13;

[0078] The cover plate 14 is adapted to the positioning groove 131 , and is disposed in the positioning groove 131 , and is sealed and connected to the bottom wall of the positioning groove 131 by welding. The cover plate 14 and the water flow groove 132 together enclose a spiral water flow channel.

[0079] Specifically, the cover plate 14 is sealed and connected to the bottom wall of the positioning groove 131 by vacuum brazing.

[0080] Specifically, the depth of the positioning groove 131 is about 1.5 mm±0.02. The thickness of the cover plate 14 is the same as the thickness of the positioning groove 131 .

[0081] Combination Figure 6 and Figure 7 As shown, in some embodiments of the present application, a boss 133 is defined between the water flow groove 132 and the bottom wall of the positioning groove 131, a support portion 1331 is formed at the center of the boss 133, and a through hole 1332 is formed at a position of the cover plate 14 corresponding to the support portion 1331, and the through hole 1332 is configured to discharge ozone generated by the ozone generator.

[0082] Specifically, a through hole 1332 is formed at a position of the cover plate 14 corresponding to the support portion 1331 , so that ozone generated by the ozone generator can be discharged easily.

[0083] Specifically, when the cover plate 14 is brazed with the main body 13, the cover plate 14 needs to be brazed with the top surface of the boss 133. When the brazing paste is placed on the boss 133, an appropriate amount of the brazing paste should be ensured. The cover plate 14 and the boss 133 are brazed together. On the one hand, the brazing strength of the cover plate 14 can be improved, and on the other hand, it is necessary to ensure that there is no water leakage between the cover plate 14 and the boss 133. The support portion 1331 at the center of the boss 133 can ensure that the gas does not enter the water flow channel from the through hole 1332 in the middle position, and at the same time, it can ensure that the water in the water flow channel does not enter the through hole 1332.

[0084] Specifically, the boss 133 is a spiral structure, and there are two bosses 133, which intersect each other. In this way, it can be ensured that water enters the water flow channel in a spiral shape, and after reaching the center of the water flow channel, continues to flow out of the water flow channel in a spiral shape.

[0085] Combination Figure 6 and Figure 7 As shown, in some embodiments of the present application, the cooling plate 1 further includes a first diverter block 15 and / or a second diverter block 16 .

[0086] The first diverter block 15 is disposed in the inner edge of the water flow channel 132 and is located near the support portion 1331;

[0087] The second diverter block 16 is disposed in the outer edge of the water flow channel 132 and is located close to the water inlet 11 .

[0088] Specifically, the width of the inner edge of the water flow groove 132 near the center and the outer edge of the water flow groove 132 near the water inlet 11 are larger. By setting a first diverter block 15 near the center of the inner edge of the water flow groove 132 and a second diverter block 16 near the water inlet 11 on the outer edge of the water flow groove 132, the first diverter block 15 and the second diverter block 16 can divert and distribute the water flow, improve the mixing degree of the water flow, and enhance the heat exchange effect between water and the cooling plate 1.

[0089] Specifically, the first diverter block 15 and the second diverter block 16 are both in an arc-shaped structure, which is consistent with the direction of the water flow channel 132 .

[0090] Combination Figure 2 As shown, in some embodiments of the present application, the main water inlet pipe 2 and the main water outlet pipe 3 are both tubular structures with unequal wall thickness;

[0091] The wall thickness of the main water inlet pipe 2 on the side of the drain port 21 is greater than the wall thickness on the side away from the drain port 21 ; the wall thickness of the main water outlet pipe 3 on the side of the water inlet 31 is greater than the wall thickness on the side away from the water inlet 31 .

[0092] In some embodiments of the present application, the main water inlet pipe 2 and the main water outlet pipe 3 are circular tubular structures.

[0093] Specifically, according to the influence of fluid dynamics, different wall thicknesses of the pipeline will affect the flow characteristics of the fluid in the pipe, including the thickness of the boundary layer and the degree of turbulence. Turbulence helps to improve the convective heat exchange system. By making the wall thickness of the main water inlet pipe 2 on the side of the drain port 21 thicker than the wall thickness on the side away from the drain port 21; the wall thickness of the main water outlet pipe 3 on the side of the water inlet 31 thicker than the wall thickness on the side away from the water inlet 31, turbulence can be promoted, thereby enhancing the heat exchange between water and the cooling plate 1.

Since the cooling device for an ozone generator according to any one of the embodiments of the first aspect is included, all of the beneficial effects thereof are possessed, and no further description is given here.
