[0035] It can be understood that the drying chamber 11 is arranged in the inner cavity of the box body 1, which is the area where the FPC is placed for drying. The heating chamber 12 is surrounded by the drying chamber 11 to generate heat, which helps to ensure the uniform distribution of temperature in the drying chamber 11; the heat preservation structure 13 is designed on the inner wall of the heating chamber 12 to retain heat, reduce heat loss, improve energy efficiency and maintain a stable drying environment; the heating component 21 in the drying structure 2 is located on the two opposite side walls of the heating chamber 12, so that the heat dissipation of the surrounding walls of the drying chamber 11 can be made more uniform during the heat dissipation process. Uniform, thereby helping to achieve uniform temperature distribution in the drying chamber 11; the guide structure 22 is arranged facing the heating component 21 and is laid on the inner wall of the heating chamber 12. The function of the guide structure 22 is to guide the hot air flow, thereby ensuring that the heat is more evenly distributed in the area closer to the drying chamber 11, thereby ensuring the drying efficiency of the products to be dried in the drying chamber 11, thereby ensuring that the heat is evenly distributed in the entire drying chamber 11, thereby improving the drying efficiency and quality, efficiently and evenly drying the FPC, while reducing energy consumption and avoiding the risk of overheating, and improving the quality of FPC products.
[0036] like Figure 3As shown, in one embodiment of the present application, the heating component 21 includes a heating net 211, a guide box 212 and a blower 213. The heating net 211 is arranged adjacent to the drying chamber 11 and partially covers the inner cavity of the heating chamber 12. The guide box 212 covers the heating net 211, and the guide box 212 is connected to the heating net 211. The blower 213 is partially penetrated by the guide box 212.
[0037] It can be understood that the heating net 211 faces the drying chamber 11 and partially covers the inner cavity of the heating chamber 12. The heating net 211 has a higher thermal efficiency. It can quickly generate heat and evenly disperse heat into the drying chamber 11, thereby ensuring that the FPC is evenly heated during the drying process; the guide box 212 covers the heating net 211 and is connected to the heating net 211. The guide box 212 can prevent direct heat loss and guide the wind blown by the blower 213 to the heating net 211, and the generated heat is evenly guided to the heating chamber 12. This design allows thermal energy to be used more effectively, thereby improving the energy efficiency of the entire system; the blower 213 is partially disposed in the guide box 212 to promote the flow of hot air, and the blower 213 pushes the hot air through the heating net 211 and the guide box 212, thereby accelerating and enhancing the air circulation in the heating chamber 12, so that the air is evenly distributed in the drying chamber 11; this structure makes the entire drying process more precise and efficient, so that the FPC can be evenly and fully dried during the drying process, thereby ensuring the performance and quality of the FPC after drying.

It uses the vacuum state to reduce air heat conduction and convection, thereby greatly improving the thermal insulation effect; the thermal insulation board 133 is attached to the outer wall of the vacuum insulation board 132. Polystyrene particles are distributed in the thermal insulation board 133, which has good thermal insulation and heat preservation properties. The distribution of polystyrene particles in the thermal insulation board 133 helps to further reduce heat transfer through convection and radiation; the outermost layer is the fireproof board 134, which is attached to the outer surface of the thermal insulation board 133. The fireproof board 134 is embedded with a glass centrifugal cotton fireproof layer. This material has a strong barrier effect on flames, thereby improving the fire resistance level of the entire structure.
[0044] like Figure 1 to Figure 2 As shown, in one embodiment of the present application, installation openings 14 are arranged at intervals on the side of the box body 1 facing away from the drying chamber 11 to install a cooling fan.
[0045] It can be understood that the installation openings 14 on the box body 1 are arranged at intervals in order to maximize the heat dissipation effect. Taking into account the space and structural strength, the installation openings 14 arranged at intervals can make the cooling fans more evenly distributed on the box body 1, thereby improving the heat dissipation efficiency; the cooling fans are installed on the box body 1, and the heat generated by the drying chamber 11 can be dissipated by forced convection, so that when these fans stop working after heating, they can significantly reduce the temperature of the box body 1 and its surrounding areas, which helps to protect the equipment from overheating damage and extend its service life. The cooling fans not only help to maintain the appropriate operating temperature of the equipment, but also prevent safety hazards caused by overheating; they are used to control the temperature of the drying chamber 11 or similar high-temperature equipment, ensure safe and efficient operation of the equipment, and improve the overall thermal efficiency and equipment safety.
