Industrial electronic drying cabinet
Industrial electronic drying cabinet:
Normal temperature automatic industrial electronic drying cabinet, currently marketed under various names such as "industrial electronic moisture-proof cabinet", "electronic drying cabinet", "moisture-proof cabinet", etc. Its dehumidification principle is divided into two categories: refrigeration type and moisture physical decomposition and removal type. Among them, the refrigeration type uses semiconductor refrigeration sheets to remove moisture from the air by condensing and condensing. Since the refrigeration type electronic moisture-proof cabinet cannot reduce the humidity to below RH10% specified by the IPC/JEDECJ-STD-033 standard, it is not discussed in this article. The moisture physical decomposition and removal type electronic moisture-proof cabinet can reduce the humidity in the cabinet to below 10%RH at room temperature. With the implementation of the IPC/JEDEC J-STD-033 standard in China, the normal temperature automatic electronic moisture-proof cabinet has begun to be widely used in the electronics industry. The moisture physical decomposition and removal type industrial electronic moisture-proof cabinet is a mechatronic product. According to the power source generated by its mechanical action, it is divided into two categories: memory alloy drive and micromotor drive. The purpose of its power is to drive the opening and closing of the dehumidification and dehumidification door of the moisture-proof box to achieve the purpose of discharging the moisture in the box to the outside of the box. Whether the dehumidification door can reliably realize the opening and closing function for a long time is the most important key factor involving the life and reliability of the moisture-proof box product and the safety of the stored items.
The so-called memory alloy is to add some nickel-titanium alloy components to the metal material, and then draw it into a spiral spring. The memory alloy spring is placed in an aluminum tube with a heating device, and then it forms a connecting rod motion mechanism with the reset tension spring and the pull rod. The heater is powered on and heated, so the memory alloy spring is shortened by heat and gradually generates tension, and the dehumidification door of the dehumidifier is opened to discharge moisture in a few minutes to more than ten minutes. After the timing is completed after dehumidification, the heater is powered off and cooled, the memory alloy spring is cooled and stretched and restored by the reset spring, so that the dehumidification door of the dehumidification host is closed, and the dehumidification host dries the air in the box. This is repeated back and forth to achieve the purpose of dehumidification.
