First, the air inlet of the cabinet is also the inlet of dust and water, so the two items need to be considered in a unified way. The air inlet needs to be designed into a waterproof structure and a slope streamline form, so that the water remaining on the plate can quickly fall through its own weight. Second, reduce the screw connection method between structural parts, maximize the use of welding structure, add a rain cover on the top, and design the contact part between the cabinet and the door plate into a flow guide groove structure.
Selection of auxiliary materials
Sealant, sealing rubber ring, used for protection of structural gap of cabinet accessories, cable joint for cable import and export and other protective measures.
Waterproof design of secondary beer molding
It is generally used in the design of sheet metal cabinet with high waterproof level, which can achieve high waterproof effect. However, the waterproof design of secondary beer plastic also has its shortcomings, that is, it is difficult to make, high cost and high maintenance cost. Therefore, only sheet metal cabinets with special requirements can use this waterproof design.
