| Summary: | 碩士 === 逢甲大學 === 機械與電腦輔助工程學系 === 104 === With continuously building of panel factories, manufacturing process is constantly progressive as well. The technology of panel factories’ manufacturing process is the key to promote the effectiveness of production and output well yield. In order to stand out, all of the factories improve their technology of manufacturing process, especially equipment and machine. Therefore, The research focuses on research and discussion in Thin Film Transistor Liquid Crystal Display (TFT-LCD) multilayer hot-air oven.
In this study, we use numerical simulation to observe the change of heat flow field inside the oven, discussing the High-Efficiency Particulate Air (HEPA) air filter in four different conditions, trends of surge plates porosity and behind the surge plates pipe. From the simulation results, the original width of HEPA is the most effective for the process; in an addition, the simulation demonstrates that the size of surge plates porosity indeed affects the flow rate, representing it can be adjusted through the surge plates in the process, when some parts of surge plate are not uniform. Finally, we respectively discuss the flow field and pressure difference in the 90 degrees, 45 degrees, arc, thinner and thinner arc. The simulation shows that the smaller arc pipe won’t have eddy currents, which means the difference of pressure in this part is almost zero; also, it represents the hot air passes through here did not be affected and the air passes out smoothly. Moreover, it means the difference of pressure in the pipe effectively avoids unnecessary wastage of wind power wheels, providing the optimal efficiency of the heating process.
