Description

Technical Field

[0001] This utility model relates to the field of monocrystalline solar cell technology, specifically to a high-efficiency cooling device for processing monocrystalline solar cells. Background Technology

[0002] Solar cells are generally classified into monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cells are currently the fastest-developing type of solar cell. Their structure and production process are well-established, and the products are widely used in space and on the ground. The production process of solar cells includes texturing, diffusion, post-cleaning, anti-reflective coating, screen printing, sintering, testing, sorting, and packaging. However, existing cooling devices typically use coolant for cooling, which achieves the purpose of cooling, but the cooling efficiency is low and cannot quickly cool the monocrystalline solar cells, resulting in low working efficiency. Therefore, we propose a high-efficiency cooling device for processing monocrystalline solar cells. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a gas pump to draw nitrogen from the inner cavity of the nitrogen tank and deliver it through a pipeline to the inner cavity of the movable cover. The movable cover then diverts the nitrogen to the inner cavity of the exhaust hood. The exhaust hood discharges the gas, rapidly cooling the internal temperature. The motor is then started, driving the fan blades to rotate. The rotation of the fan blades allows for uniform diffusion of the internal gas, resulting in a uniform temperature reduction.
