Description

Technical Field

[0001] This utility model relates to the field of solar cell module lamination technology, and more specifically to a cooling system for a laminator cooling chamber. Background Technology

[0002] In the field of solar cell module manufacturing, the cooling process after lamination plays a crucial role in ensuring module performance and quality. Traditional laminators typically use a monolithic carbon steel liquid-cooled plate for cooling. The basic principle is to machine circular channels into a 45mm thick carbon steel plate using deep-hole drilling technology, allowing cooling water to flow through, and achieving cooling through direct heat exchange between the module and the liquid-cooled plate. However, this traditional cooling structure has several limitations:

[0003] First, the overall carbon steel liquid cooling plate is quite heavy. Taking the 27115 model as an example, the cooling plate weighs as much as 10.5 tons. This not only requires the support frame to adopt a heavy structure to ensure stability, but also significantly increases the manufacturing cost of the entire cooling chamber.

[0004] Secondly, the flow channel design of the carbon steel liquid cooling plate is relatively long, with a total channel length of approximately 42.5 meters and a small unit cross-sectional area, which restricts the flow performance of the cooling water, resulting in low cooling efficiency and difficulty in achieving rapid and uniform cooling. In practical applications, it often takes 7 minutes to reduce the component temperature from 150℃ to 40℃, and the temperature uniformity can only reach ±5℃.

[0005] Furthermore, due to its material and structural characteristics, integral carbon steel liquid-cooled plates are not easily adjustable and optimized to meet different production needs. These problems not only reduce production efficiency but may also lead to uneven stress distribution in components due to uneven temperature distribution, increasing production costs and quality risks.

[0006] Therefore, developing a more efficient, economical, and flexible laminator cooling chamber cooling system is of great significance and urgent need for improving the production efficiency and quality of solar cell modules. Utility Model Content

[0007] In view of this, the present invention provides a cooling system for a laminator cooling chamber, which aims to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A cooling system for a laminator cooling chamber, located in the cooling process after heating and laminating in the laminator, includes:

[0010] A transmission frame, on which a high-temperature cloth is provided for circulating transmission, is used to transport the laminated solar cell modules;

[0011] A refrigeration module is mounted on the transmission frame and is attached to the underside of the high-temperature cloth conveyed on the upper layer. The refrigeration module is composed of multiple refrigeration unit plates. Each refrigeration unit plate has a coiled refrigeration channel inside, and the bottom surface of the refrigeration unit plate has a coolant inlet and a coolant outlet that communicate with the refrigeration channel, so that the multiple refrigeration unit plates form an independent refrigeration cycle structure.

[0012] Through the above technical solution, this utility model adopts a combination of a transmission frame and a cooling module. The cooling module consists of multiple cooling unit plates, each with a coiled cooling channel inside and a coolant inlet and outlet, forming an independent cooling circulation structure. This design can effectively improve cooling efficiency, make the cooling of solar cell modules more uniform, shorten cooling time, and reduce the manufacturing cost of the cooling chamber.

[0013] Preferably, in the above-mentioned cooling system for a laminator cooling chamber, multiple refrigeration unit plates are arranged in a 2×N configuration along the length of the transmission frame. This layout allows for more efficient use of space, resulting in more uniform cooling. It also facilitates flexible adjustment and expansion based on actual production needs, enhancing the system's adaptability and scalability.

[0014] Preferably, the cooling system for the cooling chamber of the laminator described above further includes a refrigeration piping assembly. This assembly includes two sets of secondary inlet pipes and two sets of secondary return pipes, respectively located on both sides of the transmission frame. The secondary inlet pipes on the same side are connected to the coolant inlet of the refrigeration unit plate on the same side via a tertiary inlet pipe, and the secondary return pipes on the same side are connected to the coolant outlet of the refrigeration unit plate on the same side via a tertiary return pipe. Both sets of secondary inlet pipes are connected to a primary inlet pipe arranged below them, and both sets of secondary return pipes are connected to a primary return pipe arranged below them. By configuring the refrigeration piping assembly, including the secondary inlet and secondary return pipes, and the connected tertiary inlet and tertiary return pipes, efficient coolant circulation is achieved. This piping design ensures that the coolant is evenly distributed to each refrigeration unit plate, further improving cooling efficiency and temperature control accuracy.

[0015] Preferably, in the above-mentioned laminator cooling chamber cooling system, the edge of the refrigeration unit plate has mounting holes for fixed connection with the transmission frame. The mounting holes on the edge of the refrigeration unit plate facilitate fixed connection with the transmission frame, ensuring the stability and reliability of the refrigeration unit plate during operation, preventing displacement or damage caused by vibration or other external forces, and extending the service life of the equipment.

[0016] Preferably, in the above-mentioned cooling system for a laminator cooling chamber, the refrigeration unit plate is formed by vacuum brazing a liquid-cooled bottom plate, an intermediate support plate, and a liquid-cooled top plate. The intermediate support plate is sealed between the liquid-cooled bottom plate and the liquid-cooled top plate, and has fins that form the refrigeration flow channels. This structural design not only improves the strength and sealing of the refrigeration unit plate but also enhances the heat transfer efficiency, making the cooling process more efficient.

[0017] Preferably, in the above-described cooling system for a laminator cooling chamber, the diameter of the cooling channel formed by the fins on the intermediate support plate changes intermittently, causing variations in the flow rate of the refrigerant flowing into the cooling channel. This design allows for adjustment of the refrigerant flow rate, optimizing the cooling effect, and is particularly effective in adapting to the cooling requirements of solar cell modules of different sizes or types.

[0018] Preferably, in the above-mentioned cooling system for a laminator cooling chamber, the entire cooling unit board is made of aluminum alloy. The use of aluminum alloy for the entire cooling unit board offers advantages such as light weight, good thermal conductivity, and corrosion resistance. Using aluminum alloy effectively reduces the overall weight of the cooling system, lowers the requirements for the supporting structure, thereby reducing manufacturing costs and space occupation, while simultaneously improving heat transfer efficiency and further enhancing the cooling effect.

[0019] Preferably, in the above-mentioned cooling system for a laminator cooling chamber, the thickness of the refrigeration unit plate is less than 15 mm. Reducing the size of the refrigeration unit plate makes the entire cooling system more compact and saves space. This is especially important for production environments with limited space, and it also reduces material usage, thus helping to lower costs.

[0020] Preferably, in the above-mentioned cooling system for a laminator cooling chamber, both the coolant inlet and the coolant outlet are equipped with CQC quick-connect couplings. This facilitates quick connection and disconnection of the coolant piping, improving system installation efficiency and maintenance convenience. Simultaneously, the use of quick-connect couplings ensures the sealing of the connection, reduces the risk of leakage, and ensures reliable system operation.

[0021] Preferably, in the above-mentioned laminator cooling chamber cooling system, a motor-driven chain structure is provided on the frame, which drives the high-temperature cloth to circulate. This driving method is stable and reliable, ensuring the smooth operation of the high-temperature cloth and guaranteeing the transmission stability of the solar cell module during the cooling process, which is beneficial to improving production efficiency and product quality.

[0022] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a cooling system for a laminator cooling chamber, which has the following beneficial effects:

[0023] 1. High-efficiency cooling performance: Through independent circulation of multiple cooling unit boards and optimized cooling channel design, the cooling time is greatly shortened, reducing the time for components to cool from 150°C to 40°C from 7 minutes to 5 minutes, thus improving production efficiency.

[0024] 2. Temperature uniformity: The refrigeration unit boards are arranged in a 2×N configuration. Combined with fin design and flow channel optimization, the temperature uniformity is improved from ±5℃ to ±2℃, thereby improving product quality and consistency.

[0025] 3. Cost reduction: The use of aluminum alloy reduces weight, lowering the cost of materials and supporting structures. The overall manufacturing cost of the cooling chamber is reduced by approximately 70%, significantly improving economic efficiency.

[0026] 4. Space optimization: The compact design of the refrigeration unit panel and the shortened flow channel (from 42.5 meters to 4.8 meters) reduce space requirements and adapt to different production environments.

[0027] 5. Flexibility and adaptability: The system can adjust the number and layout of refrigeration unit boards according to production needs, flexibly responding to different cooling requirements.

[0028] 6. Convenient installation and maintenance: CQC quick-connect fittings facilitate pipe connection and disconnection, improving installation and maintenance efficiency and reducing downtime.

[0029] 7. Stable operation: The motor-driven chain structure ensures stable operation of the high-temperature fabric, guarantees smooth component transmission, and improves production efficiency and quality. Attached Figure Description

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] See appendix Figure 1 To be continued Figure 5 This utility model discloses a cooling system for a laminator cooling chamber, located in the cooling process after heating and laminating in the laminator, including:

[0050] A transmission frame 1 is provided, on which a high-temperature cloth 4 is provided for circulating transmission, which is used to transport the laminated solar cell modules.

[0051] The refrigeration module 2 is mounted on the transmission frame 1 and is attached to the underside of the high-temperature cloth 4 conveyed on the upper layer. The refrigeration module 2 is composed of multiple refrigeration unit plates 21. Each refrigeration unit plate 21 has a coiled refrigeration channel 2122 inside, and the bottom surface of the refrigeration unit plate 21 has a coolant inlet 2111 and a coolant outlet 2112 that communicate with the refrigeration channel 2122, so that the multiple refrigeration unit plates 21 form an independent refrigeration cycle structure.

[0052] To further optimize the above technical solution, multiple refrigeration unit boards 21 are arranged in a 2×N configuration along the length of the transmission frame 1.

[0053] In this embodiment, there are 30 refrigeration unit boards 21, arranged in a 2×15 configuration along the length of the transmission frame 1.

[0054] See appendix Figure 5 It also includes a refrigeration piping assembly 3, which includes two sets of secondary liquid inlet pipes 33 and secondary liquid return pipes 34. The two sets of secondary liquid inlet pipes 33 and secondary liquid return pipes 34 are respectively located on both sides of the transmission frame 1. The secondary liquid inlet pipes 33 on the same side are connected to the coolant inlet 2111 of the refrigeration unit plate 21 on the same side through a tertiary liquid inlet pipe 35. The secondary liquid return pipes 34 on the same side are connected to the coolant outlet 2112 of the refrigeration unit plate 21 on the same side through a tertiary liquid return pipe 36. The two sets of secondary liquid inlet pipes 33 are connected to the primary liquid inlet pipes 31 arranged below them, and the two sets of secondary liquid return pipes 34 are connected to the primary liquid return pipes 32 arranged below them.

[0055] See appendix Figure 6 and attached Figure 7 The edge of the refrigeration unit plate 21 has mounting holes 214 that are fixedly connected to the transmission frame 1.

[0056] See appendix Figure 6 To be continued Figure 10 The refrigeration unit plate 21 is formed by vacuum brazing a liquid-cooled bottom plate 211, an intermediate support plate 212 and a liquid-cooled top plate 213. The intermediate support plate 212 is sealed between the liquid-cooled bottom plate 211 and the liquid-cooled top plate 213. The intermediate support plate 212 has fins 2121, which form a refrigeration flow channel 2122.

[0057] To further optimize the above technical solution, the diameter of the refrigeration channel 2122 formed by the fins 2121 on the intermediate support plate 212 changes intermittently, causing the flow rate of the refrigerant flowing into the refrigeration channel 2122 to change.

[0058] To further optimize the above technical solution, the entire cooling unit board 21 is made of aluminum alloy.

[0059] To further optimize the above technical solution, the thickness of the refrigeration unit board 21 is less than 15 mm.

[0060] To further optimize the above technical solution, both the coolant inlet 2111 and the coolant outlet 2112 are equipped with CQC quick-connect fittings 22.

[0061] Cooling water enters the refrigeration unit plate 21 through the CQC quick connector 22 at the coolant inlet 2111, and is diverted by the refrigeration flow channel 2122 formed by the fins 2121 to ensure uniform liquid flow. It then flows out through the CQC quick connector 22 at the coolant outlet 2112, completing the heat exchange.

[0062] To further optimize the above technical solution, a motor-driven chain structure is installed on the frame 1, which drives the high-temperature cloth 4 to circulate.

[0063] See appendix Figure 9 The diagram shows a straight section of the refrigeration channel 2122. It can be seen that the fins 2121 are densely arranged and form a break. The fins 2121 at the break are misaligned, which causes the flow rate of the refrigerant to change.

[0064] See appendix Figure 10 The diagram shows a schematic of the bent section of the cooling channel 2122. The cooling channel 2122 is as follows... Figure 8 The diagram shows a serpentine arrangement with 90° bends.

[0065] The specific workflow of this embodiment is as follows:

[0066] Module conveying: After the solar cell modules complete the lamination process, they are carried by high-temperature cloth 4 and enter the cooling chamber under the drive of transmission frame 1. Transmission frame 1 is equipped with a motor-driven chain structure. The chain drives the high-temperature cloth 4 to circulate, smoothly conveying the modules above the cooling module 2.

[0067] Refrigerant circulation: Coolant (such as water) enters the system from the primary inlet pipe 31 and is diverted to two sets of secondary inlet pipes 33. The secondary inlet pipes 33 are connected to the coolant inlet 2111 of the refrigeration unit plate 21 through the tertiary inlet pipe 35, and the coolant enters the refrigeration flow channel 2122 inside the refrigeration unit plate 21.

[0068] Cooling and heat exchange: The fins 2121 inside the refrigeration unit plate 21 form coiled refrigeration channels 2122. When the coolant flows in the channels, it exchanges heat with the high-temperature cloth 4 and components. The special design of the fins 2121 allows for dynamic adjustment of the coolant flow rate, ensuring rapid and uniform heat absorption.

[0069] Reflux and recirculation: After heat exchange, the coolant flows out from the coolant outlet 2112 of the refrigeration unit plate 21, flows through the three-stage return pipeline 36 into the second-stage return pipeline 34, and finally returns to the first-stage return pipeline 32 to complete the circulation.

[0070] Temperature control and uniformity optimization: Multiple cooling unit boards 21 are arranged in a 2×N configuration (e.g., 2×15) to ensure the transmission path covers the entire high-temperature cloth 4. Each unit operates independently, and combined with optimized flow channel design, the components are cooled more uniformly.

[0071] Using the structure of this embodiment, the time for the solar cell module to cool from 150°C to 40°C is shortened from 7 minutes to 5 minutes, the temperature uniformity is improved from ±5°C to ±2°C, and the manufacturing cost of the cooling chamber is reduced by 70%.

[0072] Compared to the overall carbon steel liquid-cooled plate, the length of the flow channel is shortened from 42.5 meters to 4.8 meters, while the unit cross-sectional area of ​​the flow channel increases by 15%, significantly improving the cooling speed and temperature uniformity. At the same time, the weight of the overall liquid-cooled plate and the support frame is reduced, resulting in a significant reduction in the manufacturing cost of the discharge platform.

[0073] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0074] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
