Description

Technical Field

[0001] This invention relates to the field of cooling device technology, specifically a gradient cooling device for thin-film solar panels. Background Technology

[0002] The manufacturing process of thin-film solar panels is inseparable from high-temperature furnace equipment. From the melting of silicon substrate and the annealing of glass substrate to the deposition and crystallization of thin films, the high-temperature furnace is a key bridge connecting "materials" and "devices". However, when thin-film solar panels are transported from the high-temperature furnace to room temperature, the large temperature difference leads to a high probability of breakage. Therefore, it is necessary to cool down the thin-film solar panels after they are taken out of the high-temperature furnace.

[0003] The existing cooling device uses a heat-insulated, enclosed multi-layer buffer rack and a lifting and retrieving mechanism for cooling. The thin-film solar panels taken out of the high-temperature furnace are stored in the buffer rack in sequence. After the buffer rack is full, the temperature control system inside the buffer rack gradually cools down the entire batch of solar panels until the solar panels are cooled to a suitable temperature. Then, the lifting and retrieving mechanism takes them out to room temperature.

[0004] Regarding the above technical conditions, there are still some drawbacks: the buffer rack and lifting and retrieving chip retrieval mechanism are offline batch cooling systems with very low production capacity, and the temperature control system must ensure uniformity while controlling the temperature inside the buffer rack.

[0005] Based on this, the present invention designs a gradient cooling device for thin-film solar panels to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a gradient cooling device for thin-film solar panels to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a gradient cooling device for a thin-film solar panel, comprising a cooling device, the cooling device including a frame, a transport structure, a protective cover, a heating structure, a heat preservation structure, and a cooling structure. The transport structure is disposed on the frame, the protective cover is disposed on the frame, and the transport structure is located between the frame and the protective cover. The protective cover includes a heating and heat preservation section and a cooling section. One end of the heating and heat preservation section is fixedly connected to a connecting plate, and the connecting plate has a connection port communicating with the transport structure. The other end of the heating and heat preservation section is connected to the cooling section. The heating structure is disposed on the heating and heat preservation section. In this section, the heating structure is located above the transport structure, the insulation structure is disposed on the outer wall of the heating and insulation section, the cooling structure is disposed in the cooling section, and the frame is provided with a control structure. The heating structure, cooling structure, and transport structure are all connected to the control structure. The temperature of the heating and insulation section is higher than the temperature of the cooling section. The temperature in the heating and insulation section decreases progressively. The temperature at the end of the heating and insulation section with the connecting plate is higher than the temperature at the end of the heating and insulation section near the cooling section. The temperature in the cooling section decreases progressively. The temperature of the cooling section near the heating and insulation section is higher than the temperature of the cooling section far from the heating and insulation section.

[0008] By adopting the above technical solution, the solar panels moving from the high-temperature equipment to the transport structure first undergo a buffer cooling process through the heating and insulation section, followed by a cooling section. This provides a buffer cooling process for the solar panels after they exit the high-temperature equipment, preventing breakage due to excessive temperature differences. The temperature in the heating and insulation section decreases progressively, with the end of the heating and insulation section containing the connecting plate having a higher temperature than the end near the cooling section. Similarly, the temperature in the cooling section decreases progressively, with the temperature near the heating and insulation section higher than the temperature further away. As the transport structure moves the solar panels from the beginning to the end of the rack, they sequentially pass through the heating and insulation section and the cooling section. The progressively decreasing temperature in both sections provides a buffer cooling process, and the combined effect of these two processes prevents breakage due to excessive temperature differences during the final cooling to room temperature.

[0009] Preferably, the heating structure includes a heating tube, a lampshade, and a mounting bracket. The mounting bracket is disposed in the heating and heat preservation section of the protective cover. The lampshade is disposed on the mounting bracket, and multiple lampshades are disposed on the mounting bracket. The heating tube is disposed on the lampshade and is located above the transport structure. The heating tube is connected to the control structure, and the heating tube is made of quartz tube material.

[0010] By adopting the above technical solution, the heating tubes are activated via a control structure. Once powered on, the heating tubes generate heat, which radiates into the insulation section, causing the temperature within that section to rise. Multiple lampshades are mounted on the mounting bracket, meaning multiple heating tubes are also installed. The control structure allows for the temperature settings of these multiple heating tubes, resulting in a gradual decrease in temperature within the insulation section. Furthermore, the quartz tube heating tubes possess characteristics such as high temperature resistance, corrosion resistance, excellent insulation, and good optical properties, resulting in superior heating performance. Preferably, the insulation structure includes insulation cotton and an insulation cover. The insulation cotton is disposed on the outer wall of the heating and insulation section, the insulation cover is disposed on the heating and insulation section, and the insulation cotton is between the insulation cover and the heating and insulation section. The insulation cotton is ceramic fiber cotton.

[0011] By adopting the above technical solution, the insulation cotton prevents the heat emitted by the heating structure in the heating and insulation section from easily escaping outwards, allowing more heat from the heating structure to be applied to the solar panels, thus improving heat utilization. The insulation cover further enhances the insulation effect of the insulation cotton on the heating and insulation section.

[0012] Preferably, the cooling structure includes a fan, an evaporator, a mounting pipe, and a mounting plate. The mounting pipe is fixedly connected to the cooling section. The fan is mounted on the mounting pipe, and multiple fans are mounted on the mounting pipe. The mounting plate is located in the cooling section. The transport structure is located between the mounting pipe and the mounting plate. The evaporator is mounted on the mounting plate, and multiple evaporators are mounted on the mounting plate. A flow channel is provided between the transport structure and the frame. The mounting pipe has multiple through holes that connect the mounting pipe to the flow channel and the evaporator to the flow channel. Both the fan and the evaporator are connected to the control structure.

[0013] By adopting the above technical solution, during cooling, the fan and evaporator are activated through a control structure, allowing air in the cooling section to circulate between the evaporator, flow channels, through-holes, fan, and evaporator. Increasing the airflow rate in the cooling section accelerates the dissipation of residual heat from the solar panels. Simultaneously, the evaporator is a crucial component of the four main refrigeration units. Low-temperature condensate passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. When the circulating air in the cooling section passes through the evaporator, it exchanges heat with the evaporator, transforming the high-temperature gas into low-temperature gas, which then re-enters the circulation, resulting in better cooling of the solar panels.

[0014] Preferably, the transport structure includes a first drive assembly, a rotating shaft, and rollers. The rotating shaft is mounted on the frame, and multiple rotating shafts are mounted on the frame. The rollers are fixedly mounted on the rotating shaft, and multiple rollers are mounted on the rotating shaft. The first drive assembly is mounted on the frame, connected to the rotating shaft, and connected to the control structure.

[0015] By adopting the above technical solution, the first drive assembly is activated through a control structure, causing multiple rotating shafts on the frame to rotate. When the solar panel is positioned on the transport structure, it rests against the rollers. As the rotating shafts rotate, the rollers rotate along with them, carrying the solar panel with them. The rollers not only support the solar panel but also reduce the contact area between the rotating shafts and the solar panel, minimizing friction scratches on the panel.

[0016] Preferably, the transport structure is divided into a transverse transport line and a longitudinal transport line, the transverse transport line and the longitudinal transport line are perpendicular to each other, the heating and heat preservation section is set at the beginning of the transverse transport line, a part of the cooling section is set on the transverse transport line, the other part of the cooling section is set on the longitudinal transport line, and a cross conveying structure is set at the end of the transverse transport line, the cross conveying structure is connected to the longitudinal transport line, and the height of the longitudinal transport line is higher than the height of the transverse transport line.

[0017] By adopting the above technical solution, the transportation structure is divided into transverse and longitudinal transportation lines, making the overall cooling device structure more centralized and its distribution and division more rational. The cross-transportation structure connects the transverse and longitudinal transportation lines, allowing the solar panels to move smoothly from the transverse to the longitudinal transportation line.

[0018] Preferably, the cross-conveying structure includes a lifting assembly, a fixed frame, and a transmission assembly. The lifting assembly is mounted on a frame at the end of the transverse transport line. The fixed frame is mounted on the lifting structure. The transmission assembly is mounted on the fixed frame and is located below the transport structure. The transmission assembly includes a second drive assembly, a rotating shaft, and fixed wheels. The rotating shaft is rotatably mounted on the fixed frame. Multiple rotating shafts are mounted on the fixed frame and are perpendicular to each other. The fixed wheels are fixedly mounted on the rotating shaft. Multiple fixed wheels are mounted on the rotating shaft and are interleaved with multiple rollers. The second drive assembly is mounted on the fixed frame and is connected to the rotating shaft and the control structure.

[0019] By adopting the above technical solution, when the solar panel is transported to the cross-conveying structure, the lifting assembly is activated, and the fixing frame rises under the action of the lifting assembly. The transmission assembly moves upward along with the fixing frame, lifting the solar panel. Because the height of the longitudinal transport line is higher than the height of the transverse transport line, the height to which the transmission assembly is lifted is now level with the height of the longitudinal transport line. The transmission assembly is then activated, and the solar panel is moved from the transmission assembly to the longitudinal transport line.

[0020] Preferably, the diameter of the fixed wheel is larger than the diameter of the roller.

[0021] By adopting the above technical solution, when the mounting frame rises under the action of the lifting component, the rotating shaft, carrying the fixed wheels, rises along with the mounting frame. Due to the diameter setting of the fixed wheels, when the solar panel is lifted by the fixed wheels, the rotating shaft will not collide with the rotating shaft.

[0022] Preferably, a plurality of guide plates are provided in the flow channel, the transport structure is between the cooling section and the guide plates, the guide plates are inclinedly arranged in the frame, and the lengths of the plurality of guide plates are different, with the guide plate closer to the mounting pipe being the longest and the guide plate closer to the evaporator being the shortest.

[0023] By adopting the above technical solution, the circulating airflow in the cooling section flows from the evaporator to the flow channel, and then from the flow channel to the through hole of the mounting pipe. During the process of the airflow flowing from the evaporator to the flow channel, the guide plate plays a guiding role, so that the airflow in the flow channel can act as much as possible on the middle part of the solar panel or the part of the solar panel away from the fan, so that the solar panel can be fully cooled.

[0024] Preferably, the frame is provided with limiting wheels, and two sets of limiting wheels are provided on the frame. The transport structure is located between the two sets of limiting wheels, and the limiting wheels are above the transport structure.

[0025] By adopting the above technical solution, when the solar panel is transported by the transport structure, the solar panel may shift during the transportation process. The limiting wheels can prevent the side wall of the solar panel from hard contacting the inner wall of the protective cover, thus avoiding damage to the solar panel from the inner wall of the protective cover.

[0026] In summary, this application has the following beneficial technical effects: 1. When the solar panel is finished processing at the high-temperature equipment, it enters the transport structure through the connection port. The transport structure moves the solar panel from the front end of the frame to the rear end. During transport, the heating, insulation, and cooling structures in the heating and insulation sections respectively provide a buffer-like cooling effect to the solar panel, preventing it from cracking or being damaged due to excessive temperature differences during the cooling process.

[0027] 2. During the cooling process from high temperature to room temperature, the solar panels remain on the transport line, reducing the offline operation time of the solar panels, accelerating the cooling efficiency of the solar panels, and improving the production efficiency of the solar panels.

[0028] 3. In the cooling section, the fan and evaporator in the cooling structure enable airflow to circulate between the evaporator, flow channels, through-holes, fan, and evaporator. This circulation accelerates the dissipation of residual heat from the solar panel by increasing the airflow rate in the cooling section. Simultaneously, multiple guide vanes are installed in the flow channels, inclined within the channels, and the lengths of these guide vanes are varying. The circulating airflow in the cooling section flows from the evaporator to the flow channels, and then from the flow channels to the through-holes of the mounting pipe. During the airflow from the evaporator to the flow channels, the guide vanes act as guides, ensuring that the airflow in the flow channels acts as much as possible on the central part of the solar panel or the part of the solar panel furthest from the fan, allowing the solar panel to receive sufficient and uniform cooling.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0034] Reference Figures 1 to 5 A gradient cooling device for a thin-film solar panel includes a cooling device comprising a frame 7, a transport structure, a protective cover, a heating structure, a heat preservation structure 2, and a cooling structure. The transport structure is mounted on the frame 7, the protective cover is mounted on the frame 7, and the transport structure is located between the frame 7 and the protective cover.

[0035] Reference Figure 1 and Figure 5 The protective cover includes a heating and insulation section 6 and a cooling section 1. A connecting plate 3 is fixedly connected to one end of the heating and insulation section 6, and the connecting plate 3 is connected to the frame 7. A connecting port 4 is provided on the connecting plate 3, and the connecting port 4 communicates with the transport structure. The connecting plate 3 of the cooling device is connected to the high-temperature equipment, so that the outlet of the high-temperature equipment is aligned with the connecting port 4.

[0036] After the solar panels are processed in the high-temperature equipment, they are moved to the transport structure via the connection port 4 of the connecting plate 3. The transport structure moves the solar panels out of the high-temperature equipment, and the protective cover protects the solar panels on the transport structure, preventing them from being damaged by external objects.

[0037] Reference Figure 1 and Figure 5 The other end of the heating and insulation section 6 is connected to the cooling section 1. The heating structure is located in the heating and insulation section 6, above the transport structure. The insulation structure 2 is located on the outer wall of the heating and insulation section 6, and the cooling structure is located in the cooling section 1.

[0038] The solar panels, moving from the high-temperature equipment to the transport structure, first undergo heating and insulation in the heating and insulation section 6, and then cooling in the cooling section 1. This provides a buffer cooling process after the solar panels leave the high-temperature equipment, preventing excessive temperature differences that could cause them to crack or be damaged.

[0039] Reference Figures 2 to 6 A control structure is installed on the frame 7, and the heating structure, cooling structure, and transport structure are all connected to the control structure. The operating status of the heating structure, cooling structure, and transport structure can be controlled through the control structure. The temperature of the heating and insulation section 6 is higher than the temperature of the cooling section 1. The heating and insulation section 6 is equipped with a heating structure and an insulation structure 2. The heating structure raises the temperature in the heating and insulation section 6, and the insulation structure 2 prevents the heat in the heating and insulation section 6 from dissipating easily.

[0040] The temperature of the heating and insulation section 6 decreases gradually, and the temperature at the end of the heating and insulation section 6 with the connecting plate 3 is higher than the temperature at the end of the heating and insulation section 6 near the cooling section 1. By setting the temperature to decrease gradually, the solar panel has a cooling buffer process after coming out of the high-temperature equipment, which prevents the solar panel from cracking and being damaged due to excessive temperature difference.

[0041] The cooling structure in cooling section 1 can lower the temperature in cooling section 1. After the solar panel has adapted to the gradual temperature drop in heating and insulation section 6, the cooling structure further cools the solar panel, allowing it to cool to room temperature more quickly.

[0042] The temperature of cooling section 1 decreases gradually, with the temperature of cooling section 1 closer to heating and insulation section 6 being higher than that of cooling section 1 further away from heating and insulation section 6. When the solar panel is transported from heating and insulation section 6 to cooling section 1, the gradually decreasing cooling temperature setting allows the solar panel to gradually adapt to the cooling temperature, avoiding damage to the solar panel due to excessive temperature difference.

[0043] Reference Figures 2 to 4The heating structure includes a heating tube 14, a lampshade 13, and a mounting bracket 15. The mounting bracket 15 is installed in the heating and insulation section 6 of the protective cover, the lampshade 13 is installed on the mounting bracket 15, and the heating tube 14 is installed on the lampshade 13. The heating tube 14 is located above the transport structure and is connected to a control structure, which can control the working state of the heating tube 14.

[0044] The heating element 14 is activated by the control structure. Once powered on, the heating element 14 generates heat, which radiates into the insulation section 6, causing its temperature to rise. The lampshade 13 concentrates the heat from the heating element 14 towards the transport structure, reducing heat loss to the outside of the protective cover. Multiple lampshades 13 are mounted on the mounting bracket 15, meaning multiple heating elements 14 are also mounted on them. The control structure allows for temperature control of multiple heating elements 14, resulting in a gradual decrease in temperature within the insulation section 6.

[0045] The heating element 14 is made of quartz tube, a tubular special glass product made of high-purity silicon dioxide, which has the characteristics of high temperature resistance, corrosion resistance, good insulation and optical properties. Using quartz tube to make the heating element 14 results in better heating performance.

[0046] Reference Figure 1 , Figure 4 and Figure 5 The insulation structure 2 includes insulation cotton 8 and an insulation cover 5. The insulation cotton 8 is placed on the outer wall of the heating and insulation section 6, and the insulation cover 5 is placed on the heating and insulation section 6, with the insulation cotton 8 positioned between the insulation cover 5 and the heating and insulation section 6. The insulation cotton 8 prevents the heat emitted by the heating structure in the heating and insulation section 6 from escaping outward, allowing more heat from the heating structure to be applied to the solar panel, thus improving heat utilization. The insulation cover 5 further enhances the insulation effect of the insulation cotton 8 on the heating and insulation section 6.

[0047] Insulation cotton 8 is ceramic fiber cotton, a highly efficient thermal insulation material belonging to the category of inorganic refractory materials. It is made from high-purity clay clinker, alumina powder, silica powder, and other raw materials, melted at high temperatures and then processed into fine fibers through blowing or spinning techniques, which are then collected into a cotton-like structure. Therefore, using ceramic fiber cotton as insulation cotton 8 improves the insulation effect of the insulation structure 2 on the heating and insulation section 6.

[0048] Reference Figure 6 , Figure 8 , Figure 12 and Figure 13The cooling structure includes a fan 19, an evaporator 26, a mounting pipe 9, and a mounting plate 12. The mounting pipe 9 is fixedly connected to the inner wall of the cooling section 1. Multiple fans 19 are mounted on the mounting pipe 9, and the airflow direction of the fans 19 is parallel to the transport structure. The mounting plate 12 is located in the cooling section 1, and the transport structure is located between the mounting pipe 9 and the mounting plate 12. Multiple evaporators 26 are mounted on the mounting plate 12.

[0049] Reference Figure 13 and Figure 14 A flow channel is provided between the transport structure and the frame 7. Multiple through holes 27 are provided on the mounting pipe 9, allowing the mounting pipe 9 to communicate with the flow channel. The evaporator 26 communicates with the flow channel, and both the fan 19 and the evaporator 26 are connected to the control structure. During cooling, the fan 19 and the evaporator 26 are activated via the control structure, allowing air in the cooling section 1 to circulate between the evaporator 26, the flow channel, the through holes 27, the fan 19, and the evaporator 26.

[0050] By accelerating airflow in cooling section 1, the dissipation of residual heat from the solar panels can be sped up. Meanwhile, the evaporator 26 is a crucial component of the four main refrigeration units. Low-temperature condensate passes through the evaporator 26, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. When the circulating air in cooling section 1 passes through the evaporator 26, it exchanges heat with the evaporator, transforming the high-temperature gas into low-temperature gas. This low-temperature gas then re-enters the circulation, further cooling the solar panels.

[0051] Reference Figures 7 to 9 The transport structure includes a first drive assembly 16, a rotating shaft 11, and rollers 10. The rotating shaft 11 is mounted on a frame 7, and multiple rotating shafts 11 are mounted on the frame 7. Multiple rollers 10 are fixedly mounted on the rotating shaft 11, and the rollers 10 are perpendicular to the rotating shaft 11. The first drive assembly 16 is mounted on the frame 7, connected to the rotating shaft 11, and connected to the control structure.

[0052] The first drive assembly 16 is activated by the control structure, causing multiple rotating shafts 11 on the frame 7 to rotate. When the solar panel is on the transport structure, it abuts against the rollers 10. As the multiple rotating shafts 11 rotate, the rollers 10 rotate along with them, carrying the solar panel with them. The rollers 10 not only support the solar panel but also reduce the contact area between the rotating shafts 11 and the solar panel, thus reducing friction scratches on the solar panel.

[0053] Reference Figure 6 and Figure 8The transport structure is divided into a transverse transport line 18 and a longitudinal transport line 17, which are perpendicular to each other. The heating and insulation section 6 is located at the beginning of the transverse transport line 18, and a part of the cooling section 1 is located on the transverse transport line 18. The other end of the cooling section 1 is located on the longitudinal transport line 17. A cross-conveying structure is provided at the end of the transverse transport line 18, which connects to the longitudinal transport line 17. The height of the longitudinal transport line 17 is higher than that of the transverse transport line 18.

[0054] The transport structure is divided into a transverse transport line 18 and a longitudinal transport line 17, making the overall cooling device structure more centralized and its distribution and division more rational. The cross-transport structure connects the transverse transport line 18 and the longitudinal transport line 17, allowing the solar panels to move smoothly from the transverse transport line 18 to the longitudinal transport line 17.

[0055] Reference Figures 8 to 10 The cross-conveying structure includes a lifting assembly 25, a fixed frame 24, and a transmission assembly. The lifting assembly 25 is mounted on the frame 7 at the end of the transverse transport line 18. The fixed frame 24 is mounted on the lifting structure, and the transmission assembly is mounted on the fixed frame 24, located below the transport structure. When the solar panel is transported to the cross-conveying structure, the lifting assembly 25 is activated, causing the fixed frame 24 to rise. The transmission assembly moves upward along with the fixed frame 24, lifting the solar panel. Because the height of the longitudinal transport line 17 is higher than the height of the transverse transport line 18, the height to which the transmission assembly is lifted is now level with the height of the longitudinal transport line 17. The transmission assembly is then activated, moving the solar panel from the transmission assembly to the longitudinal transport line 17.

[0056] Reference Figure 9 and Figure 10 The transmission assembly includes a second drive assembly 21, a rotating shaft 23, and fixed wheels 22. Multiple rotating shafts 23 are rotatably mounted on a fixed frame 24, and are perpendicular to the rotating shaft 11, located below it. Multiple fixed wheels 22 are fixedly mounted on the rotating shaft 23. The second drive assembly 21 is mounted on the fixed frame 24 and connected to the rotating shaft 23. When the second drive assembly 21 is activated by a control structure, the multiple rotating shafts 23 rotate, and the fixed wheels 22 rotate accordingly, moving the solar panel.

[0057] Reference Figure 9The fixed wheel 22 is perpendicular to the rotating shaft 23, and parallel to the rollers 10. Multiple rollers 10 and multiple fixed wheels 22 are arranged alternately. When the mounting frame 24 rises under the action of the lifting assembly 25, the rotating shaft 23, carrying the fixed wheels 22, rises along with the mounting frame 24. The diameter of the fixed wheel 22 is larger than the diameter of the rollers 10. Due to the diameter of the fixed wheel 22, when the solar panel is lifted by the fixed wheel 22, the rotating shaft 23 will not collide with the rotating shaft 11.

[0058] Reference Figure 14 Multiple guide vanes are installed in the flow channel. The transport structure is located between the cooling section 1 and the guide vanes, which are initially installed in the frame 7. The lengths of the multiple guide vanes are different, with the longest guide vane near the mounting pipe 9 and the shortest guide vane near the evaporator 26. The circulating airflow in the cooling section 1 flows from the evaporator 26 to the flow channel, and then from the flow channel to the through hole 27 of the mounting pipe 9.

[0059] As the airflow moves from the evaporator 26 to the flow channel, the guide plate acts as a guide, allowing the airflow in the flow channel to act as much as possible on the middle part of the solar panel or the part of the solar panel away from the fan 19, so that the solar panel can be fully cooled.

[0060] Reference Figure 12 and Figure 13 The frame 7 is equipped with two sets of limiting wheels 20. The transport structure is located between the two sets of limiting wheels 20, with the limiting wheels 20 positioned above the transport structure. When the solar panel is transported by the transport structure, the solar panel may shift during transport. The limiting wheels 20 prevent the side wall of the solar panel from touching the inner wall of the protective cover, thus avoiding damage to the solar panel from the inner wall of the protective cover.

[0061] The implementation principle of this embodiment is as follows: When the solar panel is removed from the high-temperature equipment, it enters the heating and insulation section 6 of the protective cover through the connection port 4, and is placed on the transport structure. The transport structure, heating structure, and cooling structure are activated by the control structure. The transport structure transports the solar panel from the heating and insulation section 6 to the cooling section 1. The temperature in the heating and insulation section 6 decreases gradually. The temperature of the heating and insulation section 6 where the connection port 4 is located is higher than the temperature of the heating and insulation section 6 near the cooling section 1. After the solar panel comes out of the high-temperature equipment, it is transported by the transport structure from the beginning to the end of the heating and cooling section 1. The solar panel has a buffered cooling process to prevent it from cracking or being damaged due to excessive temperature difference.

[0062] When the solar panel is transported to the cooling section 1 by the transport structure, the fan 19 and evaporator 26 are activated by the control structure, and an airflow circulation occurs between the evaporator 26, the flow channel, the through hole 27, the fan 19, and the evaporator 26 in the cooling section 1. During the circulation process, the remaining heat on the solar panel is dissipated until it drops to room temperature. At the same time, the temperature of the cooling section 1 also decreases gradually, with the temperature of the cooling section 1 closer to the heating and insulation section 6 being higher than the temperature of the cooling section 1 further away from the heating and insulation section 6. As the solar panel is transported from the heating and insulation section 6 to the cooling section 1, the gradually decreasing cooling temperature setting allows the solar panel to gradually adapt to the cooling temperature, avoiding damage to the solar panel due to excessive temperature difference when transitioning from the heating and insulation section to the cooling section.
