[0002] During the production of solar cells (for example, during the light injection process), it is necessary to cool the cell wafers (or called silicon wafers). The existing cooling device adopts the design of a fan motor and a flow dividing plate to blow air through the flow dividing plate to the silicon wafers for cooling. In daily production, the flow dividing plate device is used to cool the silicon wafers. In order to achieve uniform cooling, holes are drilled on the flow dividing plate to make the blown air disperse and blow towards the silicon wafers.
[0003] However, for the existing width of the flow dividing plate, the fan blows air from the bottom through the flow dividing plate towards the workpiece, so that the blown air is mainly concentrated in the middle of the workpiece, and the flow dividing plate cannot cool the whole workpiece evenly. This causes a large temperature difference across the workpiece, and the concentration in the middle leads to the fact that the fan speed cannot be too high, otherwise the workpiece will be blown up and skewed, resulting in damage. At the same time, since the wind speed cannot be increased, the cooling effect becomes worse, and the overall temperature of the workpiece is relatively high.

[0027] Embodiment 1
[0028] In order to solve the problem that the cooling effect of the flow distribution plate device in the prior art becomes poor, resulting in a relatively high overall temperature of the workpiece, this embodiment provides a flow distribution plate device. The flow distribution plate structure is used to blow air onto the silicon wafer of the photovoltaic device to cool the silicon wafer.
[0029] As Figures 1 to 2 shown, the flow distribution plate device includes an air outlet plate 10, a wind guiding structure 20, and a fan installation structure 30. The air outlet plate 10 has a plurality of flow distribution holes 101. The wind guiding structure 20 has a wind guiding channel. One end of the wind guiding structure 20 is connected to the outer peripheral edge of the air outlet plate 10. The other end of the wind guiding structure 20 converges to form an air inlet with a constricted structure. The inner wall surface of the wind guiding channel forms a wind guiding surface. The fan installation structure 30 is arranged on the side of the wind guiding structure 20 away from the air outlet plate 10. At least a part of the fan installation structure 30 is used to embed and connect with the air outlet of the fan. The air outlet of the fan is communicated with the air inlet.
[0030] Specifically, the flow distribution plate device adopted in this application uses the cooperation of the wind guiding structure 20 and the air outlet plate 10. Through the wind guiding structure 20, the air blown out by the fan is guided, so that the air flows through the wind guiding channel of the wind guiding structure 20 in sequence and then flows out from the flow distribution holes 101. The wind guiding structure 20 of this application has a wind guiding surface for wind guiding, so that the wind can flow out from the flow distribution holes 101 in a diffused manner and blow onto the silicon wafer, increasing the blowing range and changing the wind direction. By adding the wind guiding structure 20 in this application, it is beneficial to increase the blowing area of the gas flowing out from the flow distribution holes 101 of the air outlet plate 10, improve the uniformity of blowing, improve the heat dissipation efficiency and the uniformity of heat dissipation, and facilitate the overall cooling of the silicon wafer.
[0031] Furthermore, the area of the opening at the end where the wind guiding structure 20 is connected to the air outlet plate 10 is larger than the area of the opening at the end where the wind guiding structure 20 is away from the air outlet plate 10. Thus, after the air flowing out of the fan enters the interior of the wind guiding channel, under the guiding action of the wind guiding surface of the wind guiding channel, the wind will flow to the flow distribution holes 101 in a gradually diffused manner. Furthermore, the wind flowing out from the flow distribution holes 101 also increases the air outlet range under the guiding action.
[0032] Furthermore, since the area of the opening at the end where the wind guiding structure 20 is connected to the air outlet plate 10 is larger than the area of the opening at the end where the wind guiding structure 20 is away from the air outlet plate 10, the wind guiding surface is an inclined surface structure. The air outlet plate 10 is a rectangular plate structure. Thus, a conical structure is formed in the wind guiding structure 20.
[0033] In this embodiment, the specific number of the plurality of diversion holes 101 can be adaptively set. There is no limitation on the arrangement mode of the plurality of diversion holes 101 here. It can be set in an array of N rows and M columns, or it can be arranged in a single row. The specific arrangement mode is adjusted according to the actual situation. Specifically, N is a positive integer such as 1, 2, 3, etc., M is a positive integer such as 1, 2, 3, etc., and the values of N and M are determined according to the actual situation and can be the same or different. There is no restriction here.
[0034] As shown in Figure 1, along the circumferential direction of the air outlet plate 10, the air guiding structure 20 includes a plurality of air guiding plate segments connected end to end in sequence. The air guiding plate segments are straight plate structures arranged at an angle with the air outlet plate 10. One ends of the plurality of air guiding plate segments far away from the air outlet plate 10 form a rectangular air inlet.
[0035] Specifically, one ends of the straight plate structure air guiding plate segments far away from the air outlet plate 10 are gathered to form an air inlet with an opening area smaller than that of the air outlet plate 10. Each air guiding plate segment has an air guiding surface, and the air guiding surface is an inclined surface structure. Under the guidance of the air guiding surface, the air flows along the inclined surface structure, which is convenient for realizing the diffusive flow of the air.
[0036] Further, the plurality of air guiding plate segments have a pair of first plate segments 210 arranged in pairs and a pair of second plate segments 220 arranged in pairs. That is, there are two first plate segments 210 and two second plate segments 220. The two first plate segments 210 are arranged oppositely and extend along the length direction of the air outlet plate 10, and the two second plate segments 220 are arranged oppositely and extend along the width direction of the air outlet plate 10. Among them, the extension length of the first plate segment 210 is greater than that of the second plate segment 220.
[0037] Further, the pair of two first plate segments 210 arranged in pairs are arranged at a first angle with the air outlet plate 10, and the pair of two second plate segments 220 arranged in pairs are arranged at a second angle with the air outlet plate 10. The first angle and the second angle are the same or different. The first angle and the second angle can be the same or different, and the settings of the first angle and the second angle can be adaptively set according to needs.
[0038] In this embodiment, the air guiding structure 20 and the fan installation structure 30 are integrally formed. The integrally formed structure is convenient for production and processing and is beneficial to improving production efficiency.
[0039] As shown in Figure 1, the fan installation structure 30 includes a rectangular sleeve. The sleeve has a channel structure. The first end of the sleeve is connected to the other end of the air guiding structure 20, the second end of the sleeve extends toward the side far away from the air outlet plate 10, and at least a part of the second end of the sleeve is embedded in the air outlet of the fan. The air outlet of the fan is communicated with the air inlet through the channel structure.
[0040] Specifically, the sleeve is used for installation and positioning with the fan. At the same time, the channel structure formed by the sleeve can direct the wind generated by the fan to the air inlet. By setting the sleeve to connect with the fan, it is beneficial to strengthen the installation stability between the flow dividing plate device and the fan, and can direct the wind of the fan.
[0041] Furthermore, the sleeve includes a pair of first pipe wall segments 310 arranged in pairs and a pair of second pipe wall segments 320 arranged in pairs. One end of the two first pipe wall segments 310 arranged in pairs, which is far from the air outlet plate 10, extends into the interior of the air outlet of the fan. One end of the two second pipe wall segments 320 arranged in pairs, which is far from the air outlet plate 10, is bent, and the bent part of the second pipe wall segment 320 is connected to the fan.
[0042] Among them, the structure in which the bent part of the second pipe wall segment 320 is connected to the fan can be fixed by fasteners, such as bolts, or can also be fixed by welding.
[0043] Furthermore, the first pipe wall segment 310 extending into the interior of the air inlet of the fan is connected to the air outlet of the fan in an embedded manner, which is convenient for installation and beneficial to improving the installation stability. At the same time, it also has the effect of avoiding air leakage.
[0044] In this embodiment, one end of the second pipe wall segment 320, which is far from the air outlet plate 10, is bent to form a bent section, and the bent section is arranged parallel to the air outlet plate 10. The bent section is used for fixedly connecting with the fan. The bent section being arranged parallel to the air outlet plate 10 facilitates the surface-to-surface fit between the bent section and the fan, thereby increasing the contact area and being beneficial to improving the connection stability between the bent section and the fan.
[0045] In this embodiment, the length H of the air outlet plate 10 satisfies 400mm ≤ H ≤ 500mm, and the width h of the air outlet plate 10 satisfies 130mm ≤ h ≤ 160mm. If the length and width of the air outlet plate 10 are too large, it will affect the overall installation stability and is not convenient for installation; if the length and width of the air outlet plate 10 are too small, it will affect the heat dissipation effect and cannot achieve the overall heat dissipation of the silicon wafer. Preferably, the length H of the air outlet plate 10 is 454mm and the width h is 144mm.
[0046] In this embodiment, the air outlet plate 10, the air guiding structure 20, and the fan installation structure 30 are all made of stainless steel.

[0049] Specifically, the photovoltaic device further includes a fan. At least a part of the fan installation structure 30 of the flow splitter device is connected to the fan. The air outlet of the fan communicates with the air inlet of the air guiding structure 20 of the flow splitter device, and the fan is used to supply air to the inside of the air guiding structure 20.
[0050] For example, the photovoltaic device can be a light injection device, a sintering device, or other devices that require heat treatment. Taking the photovoltaic device as a light injection device as an example, when the photovoltaic device performs light injection, air is supplied to the flow splitter device through the fan, and the air flowing out of the flow splitting holes 101 of the flow splitter device blows towards the silicon wafer to achieve the technical effect of cooling the silicon wafer. Due to the setting of the air guiding structure 20 of the present application, it is beneficial to form a diffusion flow channel for the air flowing out of the flow splitting holes 101, increase the area of the air outlet region, and then perform a cooling treatment on the entire silicon wafer structure.
[0051] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

The air guiding structure 20 is used to guide the air blown out by the fan, so that the air flows through the air guiding channel of the air guiding structure 20 in sequence and then flows out from the flow splitting holes 101. The air guiding structure 20 of the present application has an air guiding surface for air guiding, so that the air can flow out from the flow splitting holes 101 in a diffused manner and blow towards the silicon wafer, increasing the blowing range and changing the wind direction. The setting of the air guiding structure 20 in the present application is beneficial to increasing the blowing area of the gas flowing out of the flow splitting holes 101 of the air outlet plate 10, improving the uniformity of blowing, improving the heat dissipation efficiency and the uniformity of heat dissipation, and facilitating the overall cooling of the silicon wafer.
