Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic module cooling devices, and particularly relates to a rapid cooling device for photovoltaic modules. Background Art

[0002] At present, the laminating plates involved in photovoltaic laminators are usually made of a rubber material with a certain flexibility, and the lower surface facing the photovoltaic module is in a flat form. Currently, in the photovoltaic industry, when using a laminator, due to process requirements, the temperature of the module is as high as 140 degrees. After the material comes out, it is cooled by the fan on the discharge table for 8 minutes, and the temperature of the module is about 50 degrees. The temperature is too high, resulting in warping of the module, making it difficult to cut the edges cleanly, and the frame is prone to bursting. Moreover, the production line has a fast rhythm, and the temperature is still higher than 25 degrees after curing, so the IV test cannot be carried out.

[0003] The patent application number "CN202120287319.2" records "a photovoltaic module laminator, which has a lamination chamber and a laminating plate that moves up and down on the lower side of the lamination chamber. The lower surface of the laminating plate has a working area corresponding to the position of the photovoltaic module to be laminated. The lower surface of the laminating plate protrudes downward at the peripheral position of the working area to form a convex platform, and the convex platform at least includes corner protection parts located outside the four corners of the working area."

[0004] Based on the above patent for a photovoltaic module laminator, since the lower surface of the laminating plate protrudes downward at the peripheral position of the working area to form a convex platform, and the convex platform at least includes corner protection parts located outside the four corners of the working area; when laminating and forming a photovoltaic module, the corner protection parts can effectively block the pressure of the laminating plate on the four corners of the photovoltaic module, and thus can reliably solve the problem that the four corners of the photovoltaic module are relatively thin or even there is a problem of crushing the glass. Moreover, in the specific application scenario of this technical solution, compared with the prior art, it does not additionally increase the work of the operator.

[0005] When laminating and forming a photovoltaic module in the above patent, the corner protection parts can effectively block the pressure of the laminating plate on the four corners of the photovoltaic module, and thus can reliably solve the problem that the four corners of the photovoltaic module are relatively thin or even there is a problem of crushing the glass. Moreover, in the specific application scenario of this technical solution, compared with the prior art, it does not additionally increase the work of the operator. However, for the laminator used in the above device, due to process requirements, the temperature of the module is as high as 140 degrees. After the material comes out, it is cooled by the fan on the discharge table for 8 minutes, and the temperature of the module is about 50 degrees. The temperature is too high, resulting in warping of the module, making it difficult to cut the edges cleanly, and the frame is prone to bursting. Moreover, the production line has a fast rhythm, and the temperature is still higher than 25 degrees after curing, so the IV test cannot be carried out. Summary of the Invention

[0006] The purpose of the present utility model is to provide a rapid cooling device for photovoltaic modules, aiming to solve the problems in the prior art that due to process requirements, the temperature of the modules in the laminator is as high as 140 degrees. After the material comes out, it is cooled by the fan on the discharge table for 8 minutes, and the temperature of the modules is about 50 degrees, which is too high, resulting in warping of the modules, incomplete trimming of the edges, easy bursting of the component frames, and a fast production line rhythm. After curing, the temperature is still higher than 25 degrees, and IV testing cannot be carried out.
