| Abstract:In order to improve the drying performance of the coating drying system, 3D modeling and fluid simulation software are used to simulate the flow field of the drying oven of the coating machine. The analysis results show that the temperature of the drying oven flow field is uneven in the length direction and the temperature variance at each nozzle is large. Aiming at the above problems, the structure of the oven was optimized from the Angle radius of the baffle, the position of the air inlet and the number of the baffle. It was found that increasing the corner radius of the baffle would increase the temperature of the two air noses close to the back of the baffle, and the change of the position of the air inlet of the oven would significantly increase the temperature distribution on the surface of the substrate. Increasing the number of baffle and rationally setting its structure size and space position can reduce the temperature distribution of the substrate surface by making the hot air stay in the middle of the air chamber of the oven. According to the above conclusions, an oven model is designed to reduce the average temperature difference at each air nozzle from ±4.5℃ to ±2.5℃, which can provide reference and theoretical basis for subsequent oven design or optimization. |
