[0023] Next, in combination with the drawings and specific implementation manners, the present utility model will be further described:

[0024] As Figure 1 、 2 shown, a processing and cooling device for a photovoltaic thin film 10 includes a cooling box 1 and an air-cooling component 2 for cooling the photovoltaic thin film 10. A pre-cooling chamber 11 and a cooling chamber 12 are provided in the cooling box 1. An inlet 1a is provided on the pre-cooling chamber 11, and an outlet 1b is provided on the cooling chamber 12. A communication port 1c is provided between the pre-cooling chamber 11 and the cooling chamber 12. The air-cooling component 2 is arranged in the cooling chamber 12. The photovoltaic thin film 10 enters the pre-cooling chamber 11 and the cooling chamber 12 in sequence from the inlet 1a and is discharged from the outlet 1b. The air-cooling component 2 is located above the photovoltaic thin film 10;

[0025] An air guiding component 3 is provided outside the cooling box 1, and the air guiding component 3 is used to introduce the cold air that has absorbed heat in the cooling chamber into the pre-cooling chamber 11;

[0026] A guiding component 4 is provided outside and / or inside the cooling box 1, and the guiding component 4 is used to make the photovoltaic thin film 10 enter and exit the cooling box 1 flat.

[0027] In this embodiment, under the conveying, traction and guiding actions of the external winding and unwinding assembly and the guiding assembly 4, the photovoltaic film 10 enters the cooling box 1. First, the air-cooling assembly 2 in the cooling chamber 12 operates to generate cold air acting on the photovoltaic film 10 below, cooling down the photovoltaic film 10. Then, the cold air after absorbing heat enters the pre-cooling chamber 11 under the action of the air guiding assembly 3 to pre-cool and cool down the photovoltaic film 10 before it enters the cooling chamber 12. Such a structural design, compared with the prior art, not only realizes the secondary utilization of cold air, reduces the cooling requirements of the air-cooling assembly 2, but also improves the cold air effect and efficiency on the photovoltaic film 10, achieving energy-saving and efficient cooling.

[0028] Further, as Figure 1 、 2 shown, the air-cooling assembly 2 includes a cold air box 21, a condensation pipe 22, and a cooling water circulation system 23.

Under the action of the air guiding assembly 3, a negative pressure is formed in the cooling chamber 12, and normal temperature air enters the cold air box 21 and forms cold air after absorbing heat through the condensation pipe 22. The cold air blows from the plurality of air holes 21b onto the surface of the photovoltaic film 10, absorbs heat and then winds around to the back from both sides of the photovoltaic film 10 and is introduced into the pre-cooling chamber 11 by the air guiding assembly 3, achieving full-coverage cooling of the front and back surfaces of the photovoltaic film 10, thereby realizing efficient cooling and temperature reduction of the photovoltaic film 10.

[0033] In this embodiment, after absorbing heat, the cold air enters the pre-cooling chamber 11 under the action of the second fan 32 and the air guiding pipe 31. A part of it directly pre-cools the photovoltaic film 10, and the other part enters the pre-cooling chamber 11 to stably maintain the temperature of the pre-cooling chamber 11 at the set low temperature, thereby reducing the influence of the change of the external environmental temperature and improving the cooling stability.

[0034] Furthermore, as Figure 1 , 2 shown, in order to improve the flattening effect and conveying smoothness of the photovoltaic film 10 in the cooling box 1; the guiding assembly 4 includes an outer guiding roller group 41 and an inner guiding roller group 42. Two outer guiding roller groups 41 are provided, which are respectively located outside the feeding port 1a and the discharging port 1b, and the inner guiding roller group 42 is arranged in the cooling chamber 12 and / or the pre-cooling chamber 11.

[0035] Furthermore, as Figure 1 shown, in order to accurately control and detect the temperature of the pre-cooling chamber 11 and the temperature of the cold air blown out by the cold air box 21; a first temperature sensor 5 is arranged in the cooling chamber 12, and a second temperature sensor 6 is arranged at the air hole 21b of the cold air box 21; through the arrangement of the temperature sensors, the rotation speeds of the first fan 24 and the second fan 32 can be controlled according to the temperature of the pre-cooling chamber 11 and the temperature of the cold air at the air hole 21b of the cold air box 21.
