Description

Technical Field

[0001] This invention relates to the field of nanocluster technology, and in particular to a cooling system based on a cluster generator. Background Technology

[0002] Nanoclusters are nanoscale structures composed of a few atoms or molecules. Due to their unique properties in terms of size effect, quantum effect, and surface activity, they have broad application potential in various fields such as catalysis, sensors, electronic devices, and biomedicine. Their advantages are mainly reflected in high surface energy, good catalytic activity, and quantum properties in specific fields. Nevertheless, the preparation of nanoclusters still faces some challenges. Conventional preparation methods, such as chemical vapor deposition, solution methods, laser evaporation, and electrochemical methods, usually require harsh conditions such as high temperature and high pressure, and it is difficult to precisely control the size and dispersion of nanoclusters. They are also complex to operate and have high energy consumption. In contrast, spark ablation generates nanocluster particles by discharging through two electrodes. It is simpler to operate and has lower energy consumption. However, the electrodes in this method work for a long time, which leads to severe electrode heating and affects production efficiency. Utility Model Content

[0003] To address the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a cooling system based on a cluster generator that is efficient, compact, compatible, and reliably sealed, so as to solve the core problem of electrode heating during long-term operation and promote the development of nanocluster preparation technology towards high efficiency, large scale, and precision.

[0004] To solve the above-mentioned technical problems, the present invention provides a cooling system based on a cluster generator for cooling the electrodes of the cluster generator. The system includes a cooling chamber, wherein the electrodes are connected to a support via a coupling, and the cooling chamber is disposed within the coupling to cool the electrodes. The system also includes an inlet pipe and an outlet pipe communicating with the cooling chamber. The inlet pipe is used to introduce a cooling medium into the cooling chamber, and the outlet pipe is used to export the cooling medium from the cooling chamber.

[0005] Furthermore, the support has a protrusion, the connecting shaft is connected to one side of the protrusion, and the cooling cavity includes a first cavity located within the connecting shaft and a second cavity located within the protrusion. The first cavity extends through the connecting shaft towards the side near the protrusion, and the second cavity extends through the protrusion towards the direction near the connecting shaft so as to communicate with the first cavity.

[0006] Furthermore, the second cavity has a connecting cavity at one end that passes through the protrusion, the connecting cavity being used for the coupling shaft to extend into so that the coupling shaft and the protrusion can be detachably connected.

[0007] Furthermore, the inner wall of the connecting cavity is machined with internal threads, and the outer wall of the end of the connecting shaft that extends into the connecting cavity is machined with external threads that match the internal threads.

[0008] Furthermore, the inner diameter of the connecting cavity is larger than the inner diameter of the second cavity to form a stepped surface between them. When the connecting shaft is connected to the connecting cavity, the end of the connecting shaft abuts against the stepped surface. A sealing groove is provided on the end wall of the connecting shaft that extends into the connecting cavity, and a sealing ring is provided in the sealing groove.

[0009] Furthermore, a first extension tube coaxial with the second cavity is provided in the second cavity. The end of the first extension tube near the connecting shaft extends axially to extend out of the second cavity. When the connecting shaft is assembled on the protrusion, the first extension tube extends to a position in the first cavity away from the protrusion. The interior of the first extension tube communicates with the first cavity. The other end of the first extension tube extends away from the connecting shaft to extend out of the protrusion and is connected to the inlet tube.

[0010] Furthermore, a first sleeve is fitted onto the end of the first extension tube away from the connecting shaft, the outer diameter of the inlet tube matches the inner diameter of the first sleeve, and the inlet tube is inserted into the end of the first sleeve away from the connecting shaft to communicate with the first extension tube.

[0011] Furthermore, the upper end of the protrusion extends upward to form a second extension tube, which communicates with the second cavity. A second sleeve is fitted on the second extension tube, and the outer diameter of the outlet tube matches the inner diameter of the second sleeve. The outlet tube is inserted into the end of the second sleeve away from the second extension tube to communicate with the second extension tube.

[0012] Furthermore, a clustering chamber is provided in the middle of the support, and two electrodes are symmetrically arranged. Each electrode is mounted on a connecting shaft. One end of the connecting shaft extends into the clustering chamber and is connected to the electrode. The other end of the connecting shaft extends outward from the clustering chamber and is connected to the support. A cooling chamber is provided in each connecting shaft, and each connecting shaft has an inlet pipe and an outlet pipe communicating with the cooling chamber.

[0013] Furthermore, a sealing assembly is provided between each of the connecting shafts and the cluster generation chamber.

[0014] The cooling system based on the cluster generator of this invention has at least the following beneficial effects: It can effectively solve the core problem of severe overheating of electrodes during long-term operation in the preparation of nanoclusters by spark ablation. By designing the cooling chamber as a first cavity within a connecting shaft and a second cavity within a protrusion, and utilizing a first extension tube within the second cavity extending to the end of the first cavity near the electrode, it achieves precise delivery of the cooling medium to the heat source. Simultaneously, the inlet and outlet positions of the inlet and outlet tubes are staggered, extending the residence time of the cooling medium in the cooling chamber, significantly improving cooling efficiency and ensuring long-term stable operation of the electrode. Regarding sealing reliability, the stepped surface at the connection between the connecting shaft and the protrusion, combined with the sealing ring in the annular sealing groove, can prevent cooling medium leakage. The three-layer connecting ring and multiple sealing rings between the connecting shaft and the cluster generation chamber can effectively prevent gas leakage from the cluster generation chamber, ensuring the formation of the nanocluster. The system offers a stable operating environment. Structurally, the cooling chamber is directly integrated into the coupling and protrusion. The inlet and outlet pipes are connected to the extension pipe via sleeves. This integrated design allows it to adapt to the existing generator frame without interfering with the adjustment function of the drive mechanism connected to the coupling for the opposing or reversing movement of the electrodes, achieving both compactness and compatibility. In terms of maintenance, the coupling and protrusion are connected by threads, allowing the coupling to be unscrewed without disassembling the entire generator. This facilitates the inspection of the cooling chamber, replacement of seals, or maintenance of the electrodes, reducing maintenance costs and downtime. Furthermore, by ensuring stable electrode operation, improving product consistency, and cooperating with electrode adjustment functions, this system promotes the development of nanocluster preparation towards higher efficiency (reducing overheating downtime), larger scale (ensuring product uniformity), and greater precision (facilitating size and performance control), providing support for its application in catalysis, sensors, biomedicine, and other fields.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Please refer to Figure 1 and Figure 2 The cooling system based on the cluster generator of this invention is used to cool the electrodes 13 of the cluster generator 1. To clearly explain the structure of the cooling system 2 (hereinafter referred to as "cooling system 2") based on the cluster generator 1 of this invention, the structure of the cluster generator 1 is described in advance: The cluster generator 1 includes a cluster generation chamber 11. A vent 12 is provided on the rear wall of the cluster generation chamber 11. The vent 12 is used to connect a gas source to introduce gas into the cluster generation chamber 11. A gas outlet 16 is provided on the front wall of the cluster generation chamber 11. Electrodes 13 for electrolyzing gas are provided on both sides of the cluster generation chamber 11. The two electrodes 13 are symmetrically arranged, and each electrode 13 passes through the side wall of the cluster generation chamber 11 via a connecting shaft 14. Based on this, the cluster generation chamber 11 is mounted on a support 15, the cooling system 2 is located between the connecting shaft 14 and the support 15, and the cooling system 2 has two sets corresponding to the two electrodes 13 respectively.

[0023] Please refer to Figure 3The cooling system 2 includes a cooling chamber 21, an inlet pipe 22, and an outlet pipe 23. A protrusion 24 is provided on the support 15 corresponding to the end of each connecting shaft 14 extending out of the clustering chamber 11. The connecting shaft 14 is detachably connected to the side of the protrusion 24 facing the clustering chamber 11. The cooling chamber 21 is formed within the connecting shaft 14 and extends into the protrusion 24; that is, the cooling chamber 21 includes a first cavity 211 located within the connecting shaft 14 and a second cavity 212 located within the protrusion 24. The inner diameters of the first cavity 211 and the second cavity 212 are equal. The first cavity 211 extends through the connecting shaft 14 towards the protrusion 24, and the second cavity 212 extends through the protrusion 24 towards the connecting shaft 14 to communicate with the first cavity 211. In this embodiment, the second cavity 212, passing through one end of the protrusion 24, also has a connecting cavity. The connecting cavity is used for the coupling shaft 14 to extend into, so that the coupling shaft 14 and the protrusion 24 can be detachably connected. Furthermore, the inner wall of the connecting cavity is machined with an internal thread 25, and the outer wall of the end of the coupling shaft 14 that extends into the connecting cavity is machined with an external thread 141 that matches the internal thread 25, so that the coupling shaft 14 and the protrusion 24 are threadedly connected. The inner diameter of the connecting cavity is larger than the inner diameter of the second cavity 212, forming a stepped surface 26 between them. When the connecting shaft 14 is connected to the connecting cavity, the end of the connecting shaft 14 abuts against the stepped surface 26. A first sealing groove 142, annular with the first cavity 211, is formed on the end wall of the connecting shaft 14 extending into the connecting cavity. A first sealing ring 143 is provided within the first sealing groove 142. When the connecting shaft 14 is connected to the protrusion 24, the bottom of the first sealing groove 142 and the stepped surface 26 abut against the first sealing ring 143 from both sides, thus improving the sealing between the connecting shaft 14 and the protrusion 24. In other embodiments, the connecting shaft 14 and the protrusion 24 can also be connected in other ways, such as by snap-fit.

[0024] A first extension tube 241, coaxial with the second cavity 212, is disposed within the second cavity 212. The end of the first extension tube 241 near the connecting shaft 14 extends axially out of the second cavity 212. When the connecting shaft 14 is mounted on the protrusion 24, the first extension tube 241 extends to a position within the first cavity 211 away from the protrusion 24, while the end of the first extension tube 241 does not contact the inner wall of the first cavity 211, thus communicating with the interior of the first cavity 211. The end of the first extension tube 241 away from the connecting shaft 14 extends in the opposite direction out of the protrusion 24.

[0025] The inlet pipe 22 is connected to the end of the first extension pipe 241 away from the connecting shaft 14. In this embodiment, a hollow first sleeve 242 with both ends extending through is fitted onto the end of the first extension pipe 241. The inner diameter of the first sleeve 242 matches both the first extension pipe 241 and the inlet pipe 22. The first extension pipe 241 and the inlet pipe 22 extend into the first sleeve 242 from both ends and are in contact with each other to communicate. The other end of the inlet pipe 22 is connected to an external cooling device to introduce cooling medium into the first extension pipe 241.

[0026] The upper end of the boss, corresponding to the position of the second cavity 212, protrudes upward to form a second extension tube 243. The second extension tube 243 is connected to the outlet tube 23, and the lower end of the second extension tube 243 extends downward to communicate with the second cavity 212. Specifically, the upper end of the second extension tube 243 is fitted with a hollow second sleeve 244 that extends through both ends. The inner diameter of the second sleeve 244 matches the outer diameter of both the second extension tube 243 and the outlet tube 23. The second extension tube 243 and the outlet tube 23 extend into the second sleeve 244 from both ends and contact each other to communicate. The other end of the outlet tube 23 communicates with an external cooling device to export the cooling medium in the cooling chamber 21. This arrangement allows the cooling medium to be directly delivered to a position closer to the electrode 13, resulting in good cooling effect. At the same time, the distance between the inlet and outlet points of the cooling medium allows the cooling medium to stay in the cooling chamber 21 for a longer time, enabling more thorough cooling of the connecting shaft 14.

[0027] Furthermore, based on the above structure, each of the connecting shafts 14 is provided with a sealing assembly 3 between itself and the cluster generation chamber 11 to increase the sealing performance of the cluster generation chamber 11. Please refer to... Figure 4The sealing assembly 3 includes a first connecting ring 31, a second connecting ring 32, and a third connecting ring 33. A connecting pipe 111 extends outward from the side wall of the clustering chamber 11 corresponding to the position where the connecting shaft 14 passes through. One end of the connecting pipe 111 communicates inward with the clustering chamber 11, and the other end communicates outward with the external air. The outer end of the connecting pipe 111 extends radially to form a raised edge 112. The outer diameter of the first connecting ring 31 matches the outer diameter of the raised edge 112, and the first connecting ring 31 and the raised edge 112 are connected and fixed to each other by a clamp 34 (the clamp 34 is a mature and common existing technology, so it will not be described in detail here). A second sealing ring 35 is also provided between the opposing surfaces of the first connecting ring 31 and the raised edge 112 to increase the sealing performance at the connection between the first connecting ring 31 and the raised edge 112. The side of the first connecting ring 31 away from the raised edge 112 has a second sealing groove 311, and the third sealing ring 312 is provided in the second sealing groove 311.

[0028] The second connecting ring 32 includes a connecting portion that is fitted and connected to the side of the first connecting ring 31 away from the protruding edge 112, and a through portion disposed on the side of the connecting portion near the first connecting ring 31. The through portion is coaxial with the connecting portion, and the outer diameter of the through portion matches the inner diameter of the first connecting ring 31 to be engaged in the middle of the first connecting ring 31. When the second connecting ring 32 and the first connecting ring 31 are fitted and fixed together, the second sealing ring 35 can increase the sealing performance between the first connecting ring 31 and the second connecting ring 32. The side of the second connecting ring 32 away from the first connecting ring 31 has a third sealing groove 321. A fourth sealing ring 322, a pressure ring 323, and a fifth sealing ring 324 are sequentially arranged axially in the third sealing groove 321. The fourth sealing ring 322, the pressure ring 323, and the fifth sealing ring 324 are all engaged in the third sealing groove 321.

[0029] The third connecting ring 33 is located on the side of the second connecting ring 32 away from the first connecting ring 31. When the third connecting ring 33 is fitted and fixed to the second connecting ring 32, the third sealing ring 312, the pressure ring 323, and the fourth sealing ring 322 can increase the sealing performance between the second connecting ring 32 and the third connecting ring 33. The inner diameters of the second connecting ring 32 and the third connecting ring 33 are matched with the outer diameter of the connecting shaft 14 so that the connecting shaft 14 can be inserted into it. The third sealing ring 312, the pressure ring 323, and the fourth sealing ring 322 are also used to increase the sealing performance between the connecting shaft 14 and the second connecting ring 32. The connecting shaft 14 passes through the third connecting ring 33, the second connecting ring 32, and the first connecting ring 31 in sequence and then extends into the cluster generation chamber 11 through the connecting tube 111.

[0030] The first connecting ring 31, the second connecting ring 32, and the third connecting ring 33 are all provided with fixing holes, and fixing bolts 36 are provided in the fixing holes to connect the first connecting ring 31, the second connecting ring 32, and the third connecting ring 33. The fixing holes and the fixing bolts 36 can be configured as screw holes and bolts, or they can be configured as other connecting parts.

[0031] Furthermore, the two connecting shafts 14 are respectively connected to a driving mechanism 4 via corresponding protrusions 24, thereby enabling the two electrodes 13 to move towards or away from each other. Each set of driving mechanisms 4 includes a driving device and a slider 42. In this embodiment, the driving device is a cylinder 41, which is mounted on the support 15. The output shaft of the cylinder 41 extends horizontally and is connected to the slider 42. The protrusion 24 is connected to the slider 42 via an L-shaped block 43, so that it can move with the movement of the slider 42.

[0032] Compared with existing technologies, the cooling system based on the cluster generator of this invention effectively solves the core problem of severe overheating of electrodes during long-term operation in the preparation of nanoclusters by spark ablation. It achieves precise delivery of the cooling medium to the heat source by designing the cooling chamber as a first cavity within a connecting shaft and a second cavity within a protrusion, with a first extension tube extending from the second cavity to the end of the first cavity near the electrode. Simultaneously, the inlet and outlet positions of the inlet and outlet tubes are staggered, extending the residence time of the cooling medium within the cooling chamber, significantly improving cooling efficiency and ensuring long-term stable operation of the electrode. Regarding sealing reliability, the stepped surface at the connection between the connecting shaft and the protrusion, combined with the sealing ring in the annular sealing groove, prevents cooling medium leakage. The three-layer connecting ring and multiple sealing rings between the connecting shaft and the cluster generation chamber effectively prevent gas leakage from the cluster generation chamber, ensuring the stability of the preparation process. The system offers several advantages. Structurally, the cooling chamber is directly integrated into the coupling and protrusion. The inlet and outlet pipes are connected to the extension pipe via sleeves. This integrated design allows it to fit the existing generator frame without interfering with the adjustment function of the drive mechanism connected to the coupling, enabling the electrodes to move in opposite directions. It combines compactness and compatibility. For maintenance, the coupling and protrusion are threaded, allowing the coupling to be unscrewed without disassembling the entire generator. This facilitates the inspection of the cooling chamber, replacement of seals, and electrode maintenance, reducing maintenance costs and downtime. Furthermore, by ensuring stable electrode operation, improving product consistency, and coordinating with electrode adjustment functions, this system promotes the development of nanocluster preparation towards higher efficiency (reducing overheating downtime), larger scale (ensuring product uniformity), and greater precision (facilitating size and performance control), supporting its application in catalysis, sensors, and biomedicine.

[0033] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
