[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] like Figures 1 to 5 As shown, an embodiment of this utility model provides a discharge cooling device, which includes a multi-layer conveying assembly 10, an air supply component 20, and a cooling unit. Each layer of the conveying assembly 10 has a movably disposed conveying section 11 that conveys the photovoltaic module 60 along a first preset direction. The cooling unit includes a multi-layer cooling pipe 30, with a cooling pipe 30 correspondingly disposed below and / or above each layer of the conveying assembly 10. Multiple air outlets 3121 are disposed on the cooling pipes 30, distributed below and / or above the corresponding conveying section 11 of the conveying assembly 10, and oriented towards the corresponding conveying section 11. The air outlet of the air supply component 20 is connected to the cooling unit, and the air blown out by the air supply component 20 is directed towards the photovoltaic module 60 on the corresponding conveying section 11 through the air outlets 3121 of each layer of cooling pipe 30.

[0048] By employing the technical solution provided in this embodiment, cooling pipes 30 are installed below and / or above the multi-layer conveying assembly 10, ensuring that the photovoltaic modules 60 on each layer of the conveying assembly 10 can be cooled uniformly and rapidly during the conveying process. The air outlets 3121 of the cooling pipes 30 are distributed, allowing direct cooling of each part of the photovoltaic module 60, avoiding cooling dead zones and improving cooling efficiency. In principle, the air blown out by the air supply component 20 enters the cooling pipes 30 and is released through the air outlets 3121, contacting the hot photovoltaic module 60 to form heat exchange, thereby rapidly reducing the temperature of the photovoltaic module 60. Using the above structure, the photovoltaic module 60 can quickly reach the specified cooling temperature on the conveying section 11, shortening the process time and increasing the production line's capacity.

[0049] In other embodiments, the cooling effect can be further optimized by increasing the number of layers of cooling pipes 30 or changing the arrangement of air outlets 3121, thus solving the technical problem of low cooling efficiency of photovoltaic modules 60 at high production line speeds. A single layer of cooling pipes 30 can be a collection of pipes laid flat in the same plane or a collection of pipes not in the same plane.

[0050] Specifically, each layer of cooling pipes 30 can be positioned below the corresponding conveying assembly 10. The conveying section 11 includes conveying rollers spaced apart along a first preset direction, with an air supply gap 111 formed between adjacent conveying rollers. The air outlet 3121 of each layer of cooling pipes 30 faces the air supply gap 111 of the corresponding conveying section 11. By positioning the cooling pipes 30 below the conveying assembly 10 and utilizing the air supply gaps between the conveying rollers, it is ensured that the cold air can directly and effectively contact the bottom of the photovoltaic module 60, improving cooling efficiency. During operation, the cold air enters through the air supply gaps and exchanges heat with the bottom of the photovoltaic module 60. Due to the gap between the photovoltaic module 60 and the conveying rollers, the cold air can be evenly distributed, avoiding uneven cooling. The structure in this embodiment makes the cooling of the bottom of the photovoltaic module 60 more uniform and rapid, further shortening the cooling time and improving the overall cooling effect.

[0051] In other embodiments, the distribution of cold air can be optimized by adjusting the gap between the conveying rollers or changing the layout of the cooling pipes 30, thereby solving the technical problem of low cooling efficiency of the photovoltaic module 60.

[0052] In this embodiment, the cooling pipe 30 includes an interconnected air supply pipe 311 and an air outlet pipe 312. The air outlet of the air supply component 20 is connected to the air supply pipe 311. The air outlet pipe 312 includes at least two air outlet branches, which are spaced apart along a second preset direction. Each air outlet branch is connected to the air supply pipe 311 and extends along a first preset direction. Air outlets 3121 are located on the air outlet branches and are spaced apart along the length of the branches. This embodiment forms a complete cooling air circulation system by setting interconnected air supply pipes 311 and air outlet pipes 312, ensuring uniform distribution and effective utilization of the cooling air. The cooling air provided by the air supply component 20 is first distributed to each air outlet pipe 312 via the air supply pipe 311, and then evenly blown onto the photovoltaic module 60 through the air outlets 3121, achieving a three-dimensional cooling effect. In terms of effectiveness, it improves the utilization rate of cold air, avoids waste of cold air, and ensures uniform cooling of the photovoltaic module 60, further improving cooling efficiency. In other embodiments, the distribution of cold air can be optimized by increasing the number of air outlet branches or adjusting the spacing of the air outlets, thus solving the technical problem of poor cooling effect on the photovoltaic module 60.

[0053] Specifically, along a first preset direction, the air supply duct 311 is located in the middle of the conveying section 11; the air supply duct 311 extends along a second preset direction, which is perpendicular to the first preset direction, i.e., the second preset direction is the width direction of the conveying section 11, and the first preset direction is the length direction of the conveying section 11. The air supply duct 311 has an air supply inlet and an air supply outlet arranged opposite to each other, with the air supply inlet located on the side of the conveying assembly 10; the air outlet duct 312 includes a first air outlet branch pipe 3122 and a second air outlet branch pipe 3123. The first air outlet branch pipe 3122 is arranged through both sides of the air supply duct 311 and extends along the first preset direction to the conveying section 11 respectively. At the lower ends of the first air outlet branch pipe 3122, a second air outlet branch pipe 3123 is located on the side of the first air outlet branch pipe 3122 away from the air inlet and is connected to the air supply pipe 311. The second air outlet branch pipe 3123 extends along a first preset direction. The length of the second air outlet branch pipe 3123 is less than the length of the first air outlet branch pipe 3122. One end of the second air outlet branch pipe 3123 is connected to the end of the air supply pipe 311, and the other end of the second air outlet branch pipe 3123 extends to the lower end of one end of the conveying unit 11. The first air outlet branch pipe 3122 and the second air outlet branch pipe 3123 are each provided with multiple air outlets 3121 along their own length direction.

[0054] By setting an air supply duct 311 in the middle of the conveying section 11 and extending it along the second preset direction, it is ensured that the cold air can be blown evenly along the second preset direction to the entire width of the conveying section 11, reducing cooling blind spots and improving the consistency of cooling of the photovoltaic module 60. The design of the first air outlet branch pipe 3122 and the second air outlet branch pipe 3123 allows the cold air to cover both ends of the conveying section 11 along the first preset direction, further ensuring uniform cooling of the photovoltaic module 60 in the first preset direction. The combination of the air supply duct 311 with the first air outlet branch pipe 3122 and the second air outlet branch pipe 3123 allows for adjustment of the length and position of the first air outlet branch pipe 3122 and the second air outlet branch pipe 3123 as needed to control the wind speed and air volume in different areas. By adjusting the position of the air supply duct 311, the length of the first air outlet branch pipe 3122 and the second air outlet branch pipe 3123, and the distribution of the air outlet 3121, the cooling requirements of different photovoltaic modules 60 can be adapted, improving the adaptability and controllability of the discharge cooling device.

[0055] In this embodiment, the cooling unit further includes an air inlet duct 32, which is disposed on the side of the plurality of conveying components 10. The side wall of the air inlet duct 32 is connected to each cooling duct 30. The air outlet of the air supply component 20 is connected to the air inlet of the air inlet duct 32. The air supplied by the air supply component is delivered to each cooling duct through the air inlet duct.

[0056] In one embodiment, the air inlet duct 32 is a vertical straight duct. The lower end of the air inlet duct 32 is designated as the air inlet, and the upper end of the air inlet duct 32 is closed. The air outlet of the air supply component 20 is connected to the lower air inlet of the air inlet duct 32. This embodiment optimizes the structure of the cooling unit by adding the air inlet duct 32, making the delivery of cold air smoother. In principle, the air inlet duct 32 is connected to the air supply component 20 to introduce cold air, and then, through its connection with each cooling duct 30, achieves uniform distribution of cold air. The technical solution in this embodiment improves the efficiency of cold air delivery, ensures uniform distribution of cold air in the cooling ducts 30, and further improves the cooling effect of the photovoltaic module 60. In other embodiments, the layout of the air inlet duct 32 or its number can be adjusted to optimize the cold air delivery path and solve the technical problem of poor cold air delivery.

[0057] Specifically, the flow cross-sectional area of ​​the air inlet duct 32 is greater than that of the cooling duct 30; and / or, the flow cross-sectional area of ​​the air outlet 3121 is less than or equal to that of the cooling duct 30.

[0058] This embodiment optimizes the flow control of cooling air by adjusting the cross-sectional areas of the air inlet duct 32 and the air outlet 3121. In principle, the cross-sectional area of ​​the air inlet duct 32 is larger than that of the cooling duct 30, ensuring a sufficient supply of cooling air. Conversely, the cross-sectional area of ​​the air outlet 3121 is smaller than or equal to that of the cooling duct 30, allowing control over the flow rate and blowing speed of the cooling air, ensuring that the cooling air reaches the photovoltaic module 60. In terms of effectiveness, the technical solution in this embodiment improves the utilization efficiency of the cooling air while ensuring the uniformity of cooling of the photovoltaic module 60, further enhancing the cooling effect.

[0059] In this embodiment, when the air outlets 3121 of the cooling pipe 30 are distributed below the conveying section 11 of the corresponding conveying assembly 10, at least a portion of the air outlets 3121 are inclined upwards towards the conveying section 11; when the air outlets 3121 of the cooling pipe 30 are distributed above the conveying section 11 of the corresponding conveying assembly 10, at least a portion of the air outlets 3121 are inclined downwards towards the conveying section 11.

[0060] This embodiment optimizes the contact between the cold air and the photovoltaic module 60 by adjusting the air outlet direction 3121, thereby improving cooling efficiency. Specifically, after the cold air is obliquely blown out of the air outlet 3121 onto the photovoltaic module 60, it diffuses along the lower surface of the photovoltaic module 60. This oblique air outlet creates a laminar flow atmosphere, ensuring uniform cooling, improving heat exchange efficiency, and better cooling the photovoltaic module 60. In other embodiments, the coverage area of ​​the cold air can be optimized by changing the tilt angle or air outlet direction, solving the technical problems of uneven cooling or condensation on the module surface.

[0061] Specifically, the discharge cooling device also includes multiple connectors 50, and the conveying assembly 10 includes a support 12. The conveying part 11 is movably mounted on the support 12, and the cooling pipe 30 is suspended below the support 12 of the corresponding conveying assembly 10 via the connectors 50. This embodiment ensures the stability of the cooling pipe 30 installation by using connectors 50 and support 12. Specifically, the connectors 50 suspend the cooling pipe 30 below the support 12, ensuring the fixed position of the cooling pipe 30 without hindering the movement of the conveying part 11, thus achieving coordinated cooling and conveying. This improves the stability of the discharge cooling device and the efficiency of component conveying, further optimizing the cooling effect. In other embodiments, the installation method of the cooling pipe 30 can be optimized by changing the structure of the connectors 50 or the design of the support 12, solving the technical problems of unstable installation of the cooling pipe 30 or its impact on the conveying of the photovoltaic module 60.

[0062] Specifically, the support 12 is the existing mounting frame for installing the conveyor roller. The mounting frame includes multiple crossbeams 40, and the connecting parts 50 are U-bolts. The U-bolts are locked onto the crossbeams 40, and the cooling pipes 30 pass through the U-bolts.

[0063] Specifically, the air supply component 20 is a fan, and the fan's outlet is connected to the cooling unit; or, the air supply component 20 is a fresh air system, and the fresh air system's outlet is connected to the cooling unit. This embodiment provides two implementation methods for the air supply component, namely a fan and a fresh air system, to meet different cooling requirements. The fan or fresh air system supplies cool air to the cooling unit through its outlet. The fan is suitable for applications requiring rapid cooling, while the fresh air system is suitable for workshops equipped with fresh air systems and applications requiring continuous and stable cooling. Through the above-mentioned configuration of the air supply component 20, a flexible cool air supply method can be provided, meeting different cooling requirements and improving the applicability of the discharge cooling device.

[0064] In other embodiments, the supply of cool air can be further optimized by combining a fan and a fresh air system, thus solving the technical problem that a single air supply method cannot meet all cooling needs. Specifically, the fan can be a high-pressure fan.

[0065] In this embodiment, there are at least two cooling units and at least two air supply components 20, with each cooling unit supplied with air through at least one air supply component 20. This embodiment uses multiple cooling units and air supply components 20, with each cooling unit connected to at least one air supply component 20, such as... Figure 2 In the illustrated embodiment, each cooling unit is connected to an air supply component 20, enabling independent air supply to each cooling unit to meet the air pressure requirements of a single cooling unit. This ensures that each cooling unit provides sufficient cool air to the photovoltaic module 60, improving cooling efficiency and flexibility. In other embodiments, the supply and distribution of cool air can be optimized by adjusting the number and layout of the cooling units and air supply components 20, thus addressing the technical problem of low cooling efficiency.

[0066] Specifically, the nth layer of cooling pipes 30 of all cooling units are on the same layer, and the cooling pipes 30 of each cooling unit on the same layer are arranged in different areas and the cooling pipes 30 of all areas blow air onto the photovoltaic modules 60 on the conveying section 11 at the same time, n≥1.

[0067] like Figure 2 As shown, the cooling unit includes two units, left and right. The first layer cooling pipes 30 of the left cooling unit and the first layer cooling pipes 30 of the right cooling unit are arranged on the same layer. The first layer cooling pipes 30 of the left cooling unit and the first layer cooling pipes 30 of the right cooling unit are arranged below the conveying section 11 of the first layer to blow air onto the photovoltaic module 60 on the conveying section 11 of the first layer for cooling.

[0068] Similarly, the second-layer cooling pipes 30 of the left-hand cooling unit and the second-layer cooling pipes 30 of the right-hand cooling unit are arranged on the same layer, and the second-layer cooling pipes 30 of the left-hand cooling unit and the second-layer cooling pipes 30 of the right-hand cooling unit are arranged below the conveying section 11 of the second layer to blow air onto the photovoltaic module 60 on the conveying section 11 of the second layer for cooling. And so on.

[0069] This embodiment achieves uniform coverage of the cooling area by placing the nth layer of cooling pipes for all cooling units on the same layer. The zoned cooling pipes 30 can simultaneously blow air onto the photovoltaic module 60, avoiding cooling dead zones and improving cooling efficiency. This allows the photovoltaic module 60 to be cooled uniformly during transport, further enhancing the cooling effect. In other embodiments, the coverage of the cooling area can be optimized by adjusting the zoned arrangement of the cooling pipes, thus solving the technical problem of uneven cooling.

[0070] Specifically, in this embodiment, for each air outlet duct 312, its air outlet 3121 includes: a plurality of first air outlets 3124 and a plurality of second air outlets 3125. The plurality of first air outlets 3124 are spaced apart along a first preset direction; the plurality of second air outlets 3125 are spaced apart along the first preset direction, and the plurality of first air outlets 3124 and second air outlets 3125 are respectively located on both sides of the air outlet duct 312. By spaced apart the plurality of first air outlets 3124 and second air outlets 3125 along the first preset direction, it is possible to ensure that the cool air is evenly distributed on the photovoltaic module 60, avoiding local overcooling or overheating, and improving the uniformity and efficiency of cooling.

[0071] Specifically, such as Figure 5 As shown, the angle between the air outlet direction of the first air outlet 3124 and / or the air outlet direction of the second air outlet 3125 and the horizontal plane is α, where 30°≤α≤60°. This structural arrangement, with the included angle α, guides the airflow along the optimal heat exchange path, avoiding excessively rapid localized cooling of the photovoltaic module 60 that might be caused by direct vertical airflow, reducing energy loss, and also contributing to improved cooling uniformity and speed. The directional airflow design prevents cold air from blowing directly vertically onto the module, reducing wind pressure on the surface of the photovoltaic module 60 and preventing positional displacement or damage to the photovoltaic module 60 during cooling due to excessive vertical wind force, thus ensuring the stability and safety of the photovoltaic module 60.

[0072] Specifically, multiple first air outlets 3124 and multiple second air outlets 3125 are arranged in a one-to-one correspondence, with each first air outlet 3124 and its corresponding second air outlet 3125 symmetrically arranged on both sides of the air outlet duct 312. This structural arrangement, by setting the first air outlets 3124 and second air outlets 3125 on both sides of the air outlet duct 312, allows for flexible adjustment of the airflow speed and volume on both sides according to the cooling requirements of the photovoltaic module 60, achieving dynamic adjustment of the cooling effect and improving the system's adaptability to different module types and sizes. Furthermore, the symmetrical arrangement of the first air outlets 3124 and second air outlets 3125 further ensures consistent cooling effect throughout the photovoltaic module 60, preventing deformation or damage to the photovoltaic module 60 during the cooling process.

[0073] The above settings optimize the distribution of the first air outlet 3124 and the second air outlet 3125 and enable precise control of the air outlet direction, allowing the discharge cooling device to provide customized cooling solutions under different working conditions and enhancing the system's controllability and flexibility in the face of complex cooling requirements.

[0074] Specifically, the diameter of the openings of the first air outlet 3124 and the second air outlet 3125 can be between 5mm and 10mm.

[0075] When the discharge cooling device of this application is in operation, the conveying section 11 receives the photovoltaic modules 60 after lamination by the laminator and transports them to their positions. Each layer of the conveying section 11 can receive one or more photovoltaic modules 60. The air supply component 20 (such as a fan or fresh air system) starts working, sending cold air through the air inlet pipe 32 into the cooling pipes 30 of each layer. The cooling pipes 30 then evenly distribute the cold air to each air outlet 3121. The cold air from the air outlet 3121 blows towards the photovoltaic modules 60 at an upward or downward angle, forming a heat exchange with the surface of the photovoltaic modules 60 and rapidly reducing the temperature of the photovoltaic modules 60.

[0076] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: they help to quickly and evenly dissipate heat from the photovoltaic module 60.
