Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a photovoltaic module heat dissipation device. Background Technology

[0002] Photovoltaic modules are the core components of solar photovoltaic power generation systems. They mainly consist of a backsheet, a first EVA layer, photovoltaic cells, a second EVA layer, and a panel. During production, these structures are stacked sequentially and then laminated in a laminator under high temperature and high pressure.

[0003] In the process of photovoltaic module research and development, the factory's R&D department usually needs to make samples. During the sample making process, various types of laminated samples will be produced, including a large number of test samples. These test samples are of different sizes and have different BOM materials. Therefore, the lamination parameters of the laminator on the production line need to be constantly changed to match the various test samples, which affects the overall production and development progress. At present, most factories' R&D centers purchase a separate offline small laminator for individual sample making.

[0004] However, stand-alone laminators only have one chamber for heating and lamination, and lack a matching heat dissipation system. This results in excessively high surface temperatures of the laminated semi-finished components, requiring a long time to cool them down before inspection and subsequent processes, which affects the work pace of employees and the progress of research and development.

[0032] To enable those skilled in the art to better understand the technical solutions in the embodiments of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art should fall within the protection scope of this utility model.

[0033] Traditional stand-alone laminators have only one chamber for heating and lamination, and lack a matching heat dissipation system. This results in excessively high surface temperatures of the laminated semi-finished components, requiring a long time to cool them down before inspection and subsequent processes, which affects the work pace of employees and the progress of research and development.

[0034] Based on this, see Figures 1 to 3 As shown, the photovoltaic module heat dissipation device provided in this embodiment of the present invention reduces the cooling time of semi-finished modules, improves working efficiency, makes the operation of semi-finished products more convenient, and reduces the damage rate of modules.

[0035] Depend on Figures 1 to 2 As can be seen, the photovoltaic module heat dissipation device provided in this utility model embodiment includes a bracket 1 and a movable component disposed at the bottom of the bracket 1. The bracket 1 includes a base 1a and a support seat 1b vertically disposed on one side of the base 1a. The movable component can be multiple outward-facing wheel sets 2. Multiple universal wheel sets 2 are distributed at intervals along the circumference of the base 1a at the bottom of the base 1a, which facilitates the photovoltaic module heat dissipation device to be pushed in various directions. For example, four universal wheel sets 2 are provided, respectively located at the four corners of the base 1a.

[0036] Depend on Figures 1 to 2 As can be seen, the photovoltaic module heat dissipation device also includes a support mechanism. This support mechanism comprises multiple support layers spaced sequentially along the vertical direction on the support base 1b. These support layers support the photovoltaic modules. The support layers can have 2, 3, 4, 5, or more layers. Each support layer includes multiple support rods 4 spaced sequentially along the horizontal direction and a detachable support partition 5 mounted on the support rod 4. The support partition 5 has multiple through holes 10, which facilitate heat dissipation for the photovoltaic modules placed on it. The support partition 5 facilitates the placement of small-sized photovoltaic modules. Depending on the actual situation, the support partition 5 can be installed on the support rod 4 or removed from it. Placing the photovoltaic modules directly on the support rod 4 results in better heat dissipation.

[0037] Specifically, one end of each support rod 4 is connected to the support base 1b, and the other end extends to the other side of the base 1a and is suspended in the air. In order to prevent the photovoltaic module from falling off the support layer, each support rod 4 is inclined in the horizontal direction, and in the vertical direction, the end of each support rod 4 connected to the support base 1b is lower than the other end of each support rod 4.

[0038] Depend on Figure 3 visible, Figure 3 This is a side view of the photovoltaic module heat dissipation device. As can be seen from the figure, the angle between each support rod 4 and the horizontal plane is greater than 0° and less than or equal to 30°. In some embodiments, the angle is greater than 1° and less than or equal to 10°, specifically 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc. Each support rod 4 has a certain degree of inclination, so that the support layer supporting the photovoltaic module also has a certain degree of inclination, avoiding the risk of the photovoltaic module falling during the process of pushing it.

[0039] The photovoltaic module heat dissipation device also includes multi-layer heat dissipation units respectively installed on the support base 1b for supplying air to each load-bearing layer, and a control system for controlling the opening and closing of the heat dissipation units.

[0040] Specifically, the heat dissipation unit has one, two, three, four, or more layers, and each layer of heat dissipation unit is located between two adjacent support layers, so that even without a heat dissipation unit on the uppermost support layer, it can still receive heat dissipation from the airflow from the heat dissipation unit. Each layer of heat dissipation unit includes multiple cooling fans 3 arranged horizontally at intervals on the support base 1b, and all cooling fans 3 in each layer of heat dissipation unit blow air towards the support layer. In this example, if there are four support layers and three heat dissipation units, each layer of heat dissipation unit has three cooling fans. In other embodiments, the number of cooling fans in each layer of heat dissipation unit can be two, four, or more.

[0041] The control system includes a power supply and multiple switches 6 electrically connected to the power supply. The power supply, switches 6, and heat dissipation units are all electrically connected via circuits. Switches 6 are used to control the opening and closing of the heat dissipation units. The heat dissipation units of each layer are connected in parallel, while the cooling fans 3 in each heat dissipation unit are connected in series. The same layer of heat dissipation unit is controlled to open or close by one switch 6, while different layers of heat dissipation units are controlled to open or close by different switches 6. In this example, three switches 6 control the opening and closing of three layers of heat dissipation units. Compared to one switch controlling the opening and closing of all heat dissipation units, the cooling fans can be turned on according to actual needs, which is more energy-efficient.

[0042] Then by Figures 2-3 As can be seen, the power supply is the battery 8 installed on the support base 1b, which avoids the use of municipal power and facilitates the movement of the photovoltaic module heat dissipation device.

[0043] To facilitate the implementation of the photovoltaic module heat dissipation device, the photovoltaic module heat dissipation device also includes a push-pull handle 7 located at one end of the support base 1b. Two push-pull handles 7 are provided, each extending in the vertical direction, and the push-pull handle 7 is located in the middle of the support base 1b.

[0044] The working principle of the photovoltaic module heat dissipation device described above:

[0045] This photovoltaic module heat dissipation device is used to dissipate heat from photovoltaic modules after lamination in a laminator.

[0046] After the laminator has laminated the test sample, push the photovoltaic module heat dissipation device next to the laminator and manually place the laminated semi-finished photovoltaic module on the support rod 4 or the support partition 5. The support rod 4 or the support partition 5 is selected according to the size of the semi-finished photovoltaic module.

[0047] See Figure 4 When the semi-finished photovoltaic module 9 is large enough to span more than two support rods 4, the semi-finished photovoltaic module is placed directly on the support rod 4; see [link / reference]. Figure 5 When the size of the semi-finished photovoltaic module 9 is small and cannot span two support rods 4, a support partition 5 is installed on the support rod 4, the semi-finished photovoltaic module is placed on the support partition 5, and then the cooling fan 3 of the corresponding layer is turned on to dissipate heat from the placed semi-finished photovoltaic module, thereby reducing the cooling time of the semi-finished photovoltaic module and improving work efficiency.

[0048] Meanwhile, during the heat dissipation process of the semi-finished photovoltaic modules, they can also be transported to the next step of the operation, making the operation of the semi-finished photovoltaic modules more convenient and reducing the damage rate of the photovoltaic modules.

[0050] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
