Description

Technical Field

[0001] The present application relates to the technical field of crystalline silicon material production equipment, and in particular to a high-performance thermal field equipment. Background Art

[0002] In the field of crystalline silicon material production equipment technology, single crystal silicon wafers have become the mainstream and trend due to their high cell efficiency. The single crystal furnace is a key piece of equipment in the single crystal manufacturing process, and the design and performance of the insulation tube directly impact the quality and efficiency of single crystal growth. The insulation tube's primary function is to maintain a stable temperature distribution in a high-temperature environment, ensuring uniform heating of the crystals and thus improving single crystal production efficiency. To enhance the performance of the insulation tube, an inner tube is often installed within the inner wall to increase its overall strength and prevent corrosion.

[0003] In practice, the most common inner barrel material is graphite cylinders. This material has excellent high-temperature resistance and a low thermal expansion coefficient, making it widely used in single crystal furnaces. Specifically, the graphite cylinder is usually cut and installed on the inner wall of the insulation barrel to enhance its structural strength. Furthermore, the graphite cylinder effectively prevents direct erosion of the insulation barrel by high-temperature gases, extending its service life. However, while the graphite cylinder improves the insulation barrel's performance to a certain extent, some problems still exist in actual use.

[0004] In existing technology, graphite cylinders are susceptible to localized corrosion in high-temperature environments, resulting in a decrease in strength in certain areas. Once corrosion occurs, these damaged areas cannot be repaired locally, requiring the entire cylinder to be replaced with a new one. This not only increases production costs but also reduces production efficiency. Therefore, how to achieve localized maintenance or repair of the inner cylinder has become a pressing technical problem. Summary of the Invention

[0005] In order to achieve local maintenance or repair of the inner barrel, the present application provides a high-performance thermal field equipment.

[0006] In the first aspect, the present application provides a high-performance thermal field equipment adopting the following technical solutions:

[0007] A high-performance thermal field equipment comprises a splicing ring body and a plurality of splicing strips, wherein the plurality of splicing strips are sequentially connected end to end to form a cylindrical splicing body, and the splicing ring body is connected to the end of the splicing body.

[0008] By adopting the above technical solution, the high-performance thermal field equipment realizes modular assembly of the inner barrel through the design of the splicing ring body and several splicing strips, which not only meets the overall strength and corrosion resistance of the equipment, but also facilitates local replacement and repair of damaged parts, thereby extending the service life of the equipment and reducing maintenance costs.

[0009] Preferably, the ends of several of the splicing strips are provided with extension strips, the splicing ring body is provided with a splicing groove, the end faces of the extension strips are fitted with the splicing ring body, and the extension strips are inserted into the splicing grooves.

[0010] By adopting this technical solution, a stable connection between the splicing strip and the splicing ring body is achieved, improving the structural strength and stability of the entire thermal field equipment. This design also allows for convenient local maintenance or replacement of the inner barrel, avoiding the problem of traditional one-piece inner barrels requiring complete replacement when damaged, thus reducing maintenance costs and time.

[0011] Preferably, the two opposite inner side walls of the splicing groove are both inclined inwards, and the angle formed by the two inner side walls after the inclination is between 25° and 35°.

[0012] By adopting the above technical solution, the contact area between the splicing groove and the extension strip can be effectively increased, so that the heat is more evenly distributed everywhere. In addition, the cross-section of the splicing groove is trapezoidal, so that the splicing strip is not easy to fall out after entering the splicing groove, thereby improving the splicing stability and reducing loosening caused by vibration or temperature changes, thereby extending the service life of the equipment.

[0013] Preferably, prefabricated grooves are provided at two opposite corners of the groove bottom of the splicing groove, and the cross section of the prefabricated groove is an inwardly concave arc shape.

[0014] By adopting the above technical solution, the provision of prefabricated grooves can effectively disperse stress concentration at the bottom of the splicing grooves, preventing cracks caused by stress concentration during long-term use, thereby extending the service life of the equipment. The cross-section of the prefabricated grooves is designed to be an inwardly concave arc, which can better adapt to the shape of the splicing strips. When the splicing strips expand due to heat, the tips of the splicing strips can also enter the prefabricated grooves, which is less likely to cause damage caused by excessive squeezing of the tips. This ensures a tight fit between the splicing strips and the splicing grooves, improving the stability and reliability of the overall structure.

[0015] Preferably, the splicing ring body includes a plurality of splicing ring modules, and the plurality of splicing ring modules are connected end to end to form a ring structure, and two adjacent splicing ring modules are detachably connected.

[0016] By adopting this technical solution, the splicing ring body is composed of multiple splicing ring modules, which can be connected end to end to form a ring structure. Adjacent splicing ring modules are detachably connected. This design allows that if a splicing ring body is partially damaged, only the damaged module needs to be replaced, eliminating the need to replace the entire splicing ring body. This significantly reduces maintenance costs and time. Furthermore, the detachable connection facilitates installation and removal, further enhancing the flexibility and ease of maintenance of the equipment.

[0017] Preferably, extension plates are provided at both ends of the splicing ring module, and the extension plates at the ends of two adjacent splicing ring modules are fitted together. A connecting block is also provided between the two adjacent splicing ring modules, and the connecting block is located on the side of the two fitted extension plates and is detachably connected to the two extension plates.

[0018] By adopting this technical solution, extension plates are installed at both ends of the splicing ring modules. The extension plates at the ends of two adjacent splicing ring modules fit together, ensuring a tight and stable connection, preventing loosening and falling of the connection, and improving the reliability of the overall structure. A connecting block is also installed between two adjacent splicing ring modules. The connecting block is located on the side of the two fitting extension plates and is detachably connected to both extension plates, making the connection more flexible, facilitating disassembly and maintenance, and reducing maintenance costs.

[0019] Preferably, the connecting block is located on a side of the extension plate away from the center of the splicing body, the connecting block is provided with a surface connecting hole, the surface connecting hole is a stepped hole, the extension plate is provided with an inner connecting hole, the connecting block is threadedly connected to the inner connecting hole after passing through the surface connecting hole by a cup head bolt to achieve connection with the extension plate.

[0020] By adopting this technical solution, the connection between the connecting block and the extension plate is more stable and reliable, avoiding the loosening problem that may occur in traditional connection methods. The stepped hole design not only improves the installation accuracy of the connecting parts, but also effectively prevents the bolts from slipping during use, thereby ensuring the stability and reliability of the entire splicing ring body.

[0021] Preferably, the extension strip is located on the side of the splicing groove facing the center of the splicing body, the extension strip is provided with an internal connecting hole, the internal connecting hole is a countersunk hole, the bottom wall of the splicing groove is penetrated by an external connecting hole, and the extension strip is threadedly connected to the external connecting hole after passing through the internal connecting hole by a countersunk bolt to achieve connection with the splicing groove.

[0022] By adopting this technical solution, a secure connection between the splicing strip and the splicing ring body is achieved, improving the structural stability of the entire thermal field equipment. The countersunk hole design prevents the bolt heads from protruding, avoiding any impact on other components and enhancing the overall aesthetics and reliability of the equipment. Furthermore, the splicing strip and extension strip are entirely constructed of a carbon-carbon composite material, which offers high toughness. Once tightened, the countersunk bolts almost sink into the carbon-carbon composite material, resulting in a smoother overall surface after installation.

[0023] In a second aspect, the present application provides a high-performance thermal field equipment, which adopts the following technical solutions:

[0024] A method for assembling high-performance thermal field equipment comprises temporarily fixing a plurality of splicing strips to corresponding positions of a splicing ring body, adjusting the relative positions of the splicing strips and the splicing ring body, adjusting the gaps between the splicing strips, and finally fixing the splicing strips to corresponding positions of the splicing ring body.

[0025] By adopting the above technical solution, the assembly method of this high-performance thermal field equipment can achieve precise positioning and fixation of the splicing strips and the splicing ring body, ensuring uniform gaps between the splicing strips, thereby ensuring the stability and sealing of the spliced ​​cylindrical structure, and effectively improving the overall performance and service life of the equipment.

[0026] Preferably, an outer airbag cover and an inner airbag support are provided during the process of temporarily fixing the splicing strips to the corresponding positions of the splicing ring body, the outer airbag cover is wrapped around the outer sides of several of the splicing strips, the inner airbag support is against the inner sides of several of the splicing strips, the inner airbag support includes several inner airbag monomers, the several inner airbag monomers are connected to each other, the several inner airbag monomers correspond one-to-one to the several splicing strips, and the several inner airbag monomers all have exhaust valves.

[0027] By adopting the above technical solution, the outer airbag cover and the inner airbag support body work together to ensure the precise positioning and stable support of the splicing strips during the assembly process, avoiding assembly errors caused by changes in the external environment and improving the installation accuracy and stability of the splicing strips. The multiple airbag monomers of the inner airbag support body enable each splicing strip to obtain uniform support force, further ensuring the flatness and alignment of the splicing strips. The design of the exhaust valve facilitates the inflation and deflation of the airbag monomers. When a splicing strip needs to be adjusted in position, the airbag monomers on the side of the splicing strip can be temporarily deflated, at which time the adjustable state of the splicing strip can be restored. After the position of the splicing strip is adjusted, the exhaust valve is closed, and the airbag monomers can be restored to the fully inflated state, thereby pressing all splicing strips inside and outside to maintain the stability of the relative position relationship of each splicing strip, so as to facilitate the subsequent installation of the splicing ring body, thereby improving work efficiency and installation convenience.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The cylindrical structure composed of the splicing ring body and splicing strips allows for local maintenance or repair of the inner cylinder, avoiding the problem of traditional graphite cylinders requiring complete replacement due to local corrosion, thereby reducing production and maintenance costs;

[0030] 2. The coordinated design of the extension strips and splicing grooves ensures a more stable connection between the strips and the splicing ring body, enhancing the structural strength of the entire inner cylinder and improving the stability and reliability of single crystal production.

[0031] 3. The inward tilt of the inner sidewall of the splicing groove and the design of the prefabricated groove are conducive to improving the sealing between the splicing strip and the splicing ring body, preventing the penetration of high-temperature gas, and further improving the thermal insulation performance and service life of the insulation tube.

[0048] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention and are not all possible implementations. Those skilled in the art can fully combine the embodiments of the present invention to derive other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0049] The inventors of this application have discovered that in the manufacturing process of crystalline silicon solar cells, single-crystal silicon wafers, due to their fewer grain boundaries and dislocations, offer higher cell efficiency, making them a mainstream development trend. During the single crystal manufacturing process, an inner barrel is typically installed within the insulation barrel of the single crystal furnace to enhance the overall insulation barrel's strength, prevent corrosion, and ensure uniform heating of the crystals, thereby improving single crystal production efficiency. However, the inner barrel of the insulation barrel in related art is typically made of a graphite cylinder, which is cut and processed from graphite raw material to enhance the inner wall strength. Regarding the aforementioned related art, the inventors believe that the following drawback exists: the production process can cause corrosion to the graphite cylinder in non-fixed locations, and the corroded areas cannot be locally repaired, thus requiring improvement. To this end, this application primarily utilizes the following solution: a splicing ring body and a plurality of splicing strips, which are sequentially connected end-to-end to form a cylindrical splicing body. The splicing ring body is connected to the end of the splicing body. This achieves the effect of localized maintenance and replacement through the splicing design, improving the reliability and cost-effectiveness of the equipment. The following is a further detailed description of the present application.

[0050] Example

[0051] Reference Figure 1 and Figure 2 The high-performance thermal field equipment provided in the embodiments of this application includes a splicing ring body 1 and a plurality of splicing strips 2. The plurality of splicing strips 2 are sequentially connected end-to-end to form a substantially cylindrical splicing body 21. In this embodiment, two splicing ring bodies 1 are provided, connected to the top and bottom of the cylindrical splicing body 21, respectively, to assemble and secure the plurality of splicing strips 2. This embodiment solves the problem in the prior art that graphite cylinders are susceptible to corrosion in high-temperature environments and cannot be locally repaired. The splicing design enables local maintenance and replacement, improving the reliability and cost-effectiveness of the equipment.

[0052] Reference Figure 2The splicing ring body 1 includes a plurality of splicing ring modules 11. In this embodiment, the number of splicing ring modules 11 is three. The three splicing ring modules 11 are connected end to end to form a ring structure, and the adjacent splicing ring modules 11 are detachably connected. The splicing ring modules 11 can be made of high-strength ceramic materials or metal alloy materials. Both materials have good high-temperature resistance and corrosion resistance. Both ends of each splicing ring module 11 are integrally formed with an extension plate 12, and the extension plates 12 at the ends of the two adjacent splicing ring modules 11 are fitted together. A connecting block 3 is also provided between the two adjacent splicing ring modules 11. The connecting block 3 is located on the side of the two fitted extension plates 12 away from the center of the cylinder.

[0053] Reference Figure 3 、 Figure 4 and Figure 5 A surface connection hole 31 is provided on the side of the connecting block 3 away from the center of the cylinder, and an inner connection hole 32 is provided through the extension plate 12. The surface connection hole 31 is a stepped hole, and the inner connection hole 32 is an ordinary threaded hole. A cup head bolt 33 passes through the surface connection hole 31 and is threadedly connected to the inner connection hole 32 to achieve connection with the extension plate 12. The end face of the cup head bolt 33 fits with the end face of the connecting block 3 to improve the overall surface flatness.

[0054] Reference Figure 3 、 Figure 6 and Figure 7 The top and bottom of the splicing strip 2 are both provided with extension strips 22. The splicing ring body 1 is provided with a splicing groove 23 corresponding to the position of the extension strip 22. The extension strip 22 is inserted into the splicing groove 23. After the extension strip 22 is inserted into the splicing groove 23, the end face of the splicing strip 2 is in contact with the splicing ring body 1 to improve the overall airtightness. The extension strip 22 is located on the side of the splicing groove 23 facing the center of the splicing body 21. The extension strip 22 is provided with an internal connection hole 24, which is a countersunk hole. The bottom wall of the splicing groove 23 is penetrated by an external connection hole 25. The extension strip 22 is connected to the splicing groove 23 by a countersunk bolt 26 passing through the internal connection hole 24 and then threaded into the external connection hole 25. In this embodiment, the splicing strip 2 is made of a carbon-carbon composite material. The carbon-carbon composite material has a lower thermal conductivity than the graphite material, which can reduce energy loss, save energy consumption, and help improve production efficiency. In addition, the carbon-carbon composite material has a higher density, which improves the overall strength of the inner cylinder, thereby extending the service life. Moreover, the carbon-carbon composite material also has high toughness. The design of the countersunk hole and the countersunk bolt 26 can make the bolt head completely embedded in the splicing strip 2, avoiding the protrusion of the bolt head and ensuring the overall surface flatness of the cylinder.

[0055] In addition, refer to Figure 3 and Figure 7The two opposite inner side walls of the splicing groove 23 are both inclined inwards and the angle formed by the two inner side walls after the inclination is between 25° and 35°. In this embodiment, it is set to 30°. This design can increase the tightness after splicing. In addition, prefabricated grooves 27 are provided at the two opposite corners of the groove bottom of the splicing groove 23. The cross-section of the prefabricated groove 27 is an inwardly concave arc. In actual processing scenarios, the splicing strip 2 will expand due to heat. At this time, the top corner of the splicing groove 23 can extend into the inside of the prefabricated groove 27 in an expanded state, so that the top corner is not easily damaged in the expanded state. In addition, the provision of the prefabricated groove 27 can effectively disperse the stress concentration at the bottom of the splicing groove 23. When the cylinder as a whole expands due to heat, each component will undergo different expansion deformations. The provision of the prefabricated groove 27 can avoid the generation of cracks at the splicing groove 23 due to stress concentration during long-term use, thereby extending the service life of the equipment.

[0056] The principle behind this embodiment is that by designing the splicing ring body 1 and splicing strips 2 as detachable structures, if a part becomes corroded or damaged, the corresponding component can be directly replaced without replacing the entire assembly, significantly reducing maintenance costs and time. Furthermore, the design of the splicing grooves 23 and extension strips 22 ensures a tight connection between the components, improving the sealing and stability of the device.

[0057] Reference Figure 8 and Figure 9 The assembly method of this embodiment includes the following steps:

[0058] 1. Temporary Fixation: Temporarily fix the plurality of splicing strips 2 to the corresponding positions of the splicing ring body 1. During the process of temporarily fixing the splicing strips 2 to the corresponding positions of the splicing ring body 1, an outer airbag cover 4 and an inner airbag support 5 are provided. The outer airbag cover 4 wraps around the outer sides of the plurality of splicing strips 2, and the inner airbag support 5 abuts against the inner sides of the plurality of splicing strips 2. The inner airbag support 5 includes a plurality of inner airbag cells 51. The plurality of inner airbag cells 51 correspond one-to-one with the plurality of splicing strips 2, and the plurality of inner airbag cells 51 are interconnected and connected to an external air source. The plurality of inner airbag cells 51 each have an exhaust valve 6. The outer airbag cover 4 also includes a plurality of outer airbag cells 41. The plurality of outer airbag cells 41 correspond one-to-one with the plurality of splicing strips 2, and adjacent outer airbag cells 41 are interconnected and connected to an external air source. The plurality of outer airbag cells 41 also have an exhaust valve 6. The inner airbag monomer 51 supports the splicing strip 2 internally and the outer airbag monomer 41 pushes the splicing strip 2 externally to assist in achieving the initial positioning and support of the plurality of splicing strips 2 .

[0059] 2. Adjust the position: Adjust the relative position of each splicing strip 2 and the splicing ring body 1 to ensure that the splicing strip 2 fits tightly and correctly with the splicing ring body 1. Adjust the gaps between each splicing strip 2 to ensure that the distance between each splicing strip 2 is uniform and consistent to avoid poor splicing due to gaps that are too large or too small. During the position adjustment process, if a splicing strip 2 needs to be adjusted, the inner airbag monomers 51 and outer airbag monomers 41 on both sides of the splicing strip 2 can be "deflated" by opening the corresponding exhaust valves 6 (during this process, the external air source continues to supply air). At this time, the air pressure of the inner airbag monomers 51 and outer airbag monomers 41 on both sides of the splicing strip 2 is relatively reduced, but they still contact the splicing strip 2. This state has more degrees of freedom than the fully contacted state, that is, the splicing strip 2 can be adjusted under manual external intervention. After the position adjustment is completed, the exhaust valves 6 can be closed again to restore the original fully contacted state.

[0060] 3. Final Fixing: Finalize the splicing strip 2 to the corresponding position on the splicing ring body 1. Specifically, insert the countersunk bolt 26 through the inner connection hole 24 and thread it into the outer connection hole 25. Insert the cup-head bolt 33 through the outer connection hole 31 and thread it into the inner connection hole 32. Finally, check the connections of all components to ensure the integrity of the device. Disconnect the external air supply, deflate the inner airbag support 5 and outer airbag cover 4, and separate them from the cylinder body to complete the assembly.

[0061] The principle behind the assembly method in this embodiment is that, with the assistance of the outer airbag cover 4 and the inner airbag support 5, the installation accuracy and stability of the splicing strip 2 can be effectively improved, simplifying the assembly process and reducing the difficulty. Furthermore, the step-by-step adjustment and final fixation procedures ensure that the various components of the device will not loosen or misalign during installation, thereby improving the overall performance and reliability of the device. This improvement not only increases assembly efficiency but also reduces assembly errors, ensuring the long-term stable operation of the device.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
