Network Rack Cabinet Heat ventilation Electromagnetic isolation Flexible size YH2004
Standard cabinets are widely used in computer network equipment, wireless communication equipment, and electronic equipment stacking. Cabinets have the advantages of enhanced electromagnetic shielding, reduced equipment operating noise, and reduced floor area occupation of equipment. For some high-end cabinets, they also have air filtering capabilities. Improve the working environment of precision equipment.
Many engineering-grade devices use a 19-inch panel width, so a 19-inch cabinet is the most common standard cabinet. There are many types and styles of 19-inch standard cabinets, as well as imported and domestic ones. The price and performance gaps are also very obvious. The price of cabinets with the same size and different levels may differ by several times. The user chooses a standard cabinet according to the specific conditions and budget of the installation of stacked equipment to select the appropriate product. The structure of standard cabinets is relatively simple, including basic frames, internal support systems, wiring systems, and ventilation systems. Standard cabinets can be divided into many performance and price grades depending on the type of assembly and materials used. The 19-inch standard cabinet has three general indicators: width, height, and depth. Although the installation width of the 19-inch panel device is 465.1mm, the common physical width of the cabinet is 600mm and 800mm. The height is generally from 0.32--2.0M, and the general cabinet size includes: 0.32 meters, 0.45 meters, 0.6 meters, 1.0 meters, 1.2 meters, 1.4 meters, 1.6 meters, 1.8 meters, and 2.0 meters. It depends on the number of devices in the cabinet and the uniform style. The depth of the cabinet is generally from 350mm-1000mm, which depends on the size of the equipment in the cabinet. Usually, the manufacturer can also customize the product with special depth. The common finished 19-inch cabinet depth is 500mm, 600mm, 700mm, 800mm. The height of equipment installed in a 19-inch standard cabinet is represented by a special unit "U", 1U = 44.45mm. Equipment panels using 19-inch standard cabinets are generally manufactured to specifications of nU (n represents quantity). For some non-standard equipment, most of them can be installed into the 19-inch chassis with additional adapters and fixed.
