Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic glass, and in particular to a horizontal photovoltaic glass thin film deposition cooling plate device. Background Art

[0002] Currently, in horizontal photovoltaic glass thin-film deposition equipment, the glass must be heated, reaching a surface temperature of approximately 200°C. This temperature is crucial after the process is completed and before the glass is transferred out of the chamber for the next step. Previous equipment has overcome this problem by directly using cooling plates with deep holes drilled through them to form water channels within the chamber to cool the glass surface.

[0003] For example, patent number CN203007401U discloses a horizontal thin film deposition cooling plate device, which includes two upper and lower cooling plate devices, each with a 5mm deep cooling plate groove inside for placing a cooling copper tube with a diameter of 10mm. The upper and lower cooling plates are locked with M6 screws.

[0004] The above-mentioned solution proposes two upper and lower cooling plates, each of which is equipped with a cooling copper tube. The cooling plates are then placed in contact with the surface of the photovoltaic glass to conduct heat and reduce the surface temperature of the photovoltaic glass during thin film deposition. However, in actual use, it was found that since the surface temperature of both sides of the photovoltaic glass film increases during deposition, the two surfaces of the photovoltaic glass film need to be repeatedly cooled during the cooling process, resulting in reduced cooling efficiency. To address this issue, a horizontal photovoltaic glass thin film deposition cooling plate device is proposed. Summary of the Invention
