Cabinet are generally made of cold-rolled steel sheet or alloy used to store computers and the relevant control equipment of objects, can provide for storage equipment protection, shielding electromagnetic interference, orderly and neatly arranged equipment maintenance equipment for later. Cabinet are generally classified into server rack, network cabinets, control cabinets, etc.
Many people put cabinet as used to hold IT equipment cabinet. Enclosure is cabinet, but is not necessarily so. For the computer itself, also has a cabinet and UPS power important supplementary role. A good cabinet means to make sure that the computer can in a good environment in operation. So, cabinet that play the roles are equally important. Now say, only have a computer where almost all existence cabinet figure. Cabinet systematically solved computer application of high-density heat dissipation, large cable attached and management, large capacity distribution and overall compatible with different business posture equipment factory problem, thus make data center can be in high availability under the environment of the operation.
At present, the computer industry cabinet has become an indispensable supplies, in each big room can see all kinds of cabinet, along with the computer industry constantly breakthroughs, cabinet that embodies the function also is more and more big. Cabinet usually in a network cabling between, the floor wiring workshop, data center machine room, computer room, network cabinet, control center, monitoring room, the monitoring center, etc.
Cabinets - basic type and structure
Common cabinet color have white, black and grey. (which divides a lot of kinds types, such as orange lines, sand grain, etc.), The cabinet material generally have aluminum cabinet, there are 9 discount profiles of cabinet, there were sixteen fold type cabinet, cold rolling steel cabinet, and hot rolled steel cabinet. Steel material, coating material, process determines the cabinet stability. Generally it long commonly used is 600,800 mm wide common is 600,800,1000 mm highly commonly used is 42U, 36U, 24U.
Early cabinet mostly used in casting or Angle by screws, rivets connection or welded into cabinet framework, add by thin plate made of flats (the door) and into. The cabinet is big and heavy, appearance pallet, have been eliminated. As the transistor, the integrated circuit and use of the various components, components of super miniaturization, the cabinet structure to miniaturization, blocks change direction. Cabinet has been made over the past the whole panel structure development become a size series inserted box, plugin structure. Insert box, plugin assembly arrangement points horizontal arrangement and perpendicular arrange two kinds. Cabinet materials widely adopted thin plate, various cross-section shape profile steel, aluminum and various kinds of engineering plastics etc. The cabinet framework besides using welding, screw connection outside, still adopt the bonding process.
Cabinet members of the cabinet by bearing, materials and manufacturing process is different, can be divided into two basic profiles and plate structure.
1 cabinet: have shaped structure cabinet and aluminum profile steel cabinet two kinds. Steel shape material by aliens seamless steel tube cabinet for pillar composition. The cabinet of the stiffness and strength are all very good, applies to heavy equipment. By aluminum alloy consisting of aluminum cabinet has certain stiffness and strength, suitable for general or light equipment. The cabinet is light weight, manufactured, beautiful appearance, less widely.
2 plate structure cabinet: the whole board type cabinet, its lateral plate for a piece of steel plate bending forming. This cabinet stiffness and strength are preferable, suitable for heavy or general equipment. But because of lateral plate is not disassemble, make assembly, maintenance is convenient. Curved plates cabinet pillar type of structure and profiles cabinet similarity pillar is by steel plate bend and into. The cabinet has certain stiffness and strength, suitable for general equipment.
According to need cabinet had a cabinet accessories. Its main accessories have fixed or retractable slideway, locking device, hinge, go trough, wiring rack and shielding comb form reeds, etc.
Cabinets - technical requirements
1 should have good technical performance. The cabinet structure should be based on the equipment of electrical, mechanical properties and use environmental requirements for necessary physical design and chemical designs to ensure the cabinet structure with good stiffness and strength and good electromagnetic isolation, grounding, noise isolation, ventilation and cooling, such as performance. In addition, cabinets should have fight vibration and impact resistance, corrosion resistance, dustproof, waterproof, prevent radiation, such as performance, so as to ensure that equipment stable working reliably.
2 should have good practicability and safety protection facilities, it is easy to operate, installation and maintenance, and can ensure the operator safety.
3 should facilitate production, assembling, testing and package transportation.
4 should conforms with the standardization, normalization, seriation requirements. Will5 modelling beautiful, applicable, color coordination.
Cabinets - classification
Along with the computer and network technology development, the cabinet is becoming an important part. Data centers, servers and network communication equipment and other IT facilities, is moving towards a miniaturization, networked, frame of the direction of development. And cabinet, are gradually becoming one of the protagonist of this change. Common cabinet can be divided into a few kinds:
According to the function points: fire antimagnetic ark, power cupboard, monitoring tracks, shielded cabinet, safety cabinet, waterproof cabinet, safe, multimedia console, filing cabinets,, hanging cabinet
Applicable scope: outdoor cabinet, indoor enclosure, communication ark, industrial safety cabinet, low voltage distribution cabinets, electric cabinet, server rack
Expand classification: console, computer case cabinet, stainless steel chassis, monitoring work station, tool ark, standard tracks, network cabinets
Server rack introduction:
In the telecom room, IDC cabinet commonly refers to server rack.
[1] for installation server, display, UPS 19 "standard equipment and non 19" standard equipment dedicated cabinets, server rack, used to assemble, install panel, plug-ins, insert box, electronic components, devices and mechanical parts and components, make its make a whole installation box. Server rack the framework and flats (the door) composition, generally with the appearance of cuboids, landing placement. It provided normal work for electronic equipment adapt to the environment and safety protection. This is the second system-level level assembly. Do not have closed structure cabinet called frame.
Server rack with good technical performance. The cabinet structure should be based on the equipment of electrical, mechanical properties and use environmental requirements for necessary physical design and chemical designs to ensure the cabinet structure with good stiffness and strength and good electromagnetic isolation, grounding, noise isolation, ventilation and cooling, such as performance. In addition, server rack should have fight vibration and impact resistance, corrosion resistance, dustproof, waterproof, prevent radiation, such as performance, so as to ensure that equipment stable working reliably. Server rack should have good practicability and safety protection facilities, it is easy to operate, installation and maintenance, and can ensure the operator safety.
Server rack specifications:
Server rack in the cabinet depth, height, bearing etc. Have a demand. Height 2 meters, 1.8 meters, 1.6 meters three height, The width to 700mm or 600mm 800mm, three, Depth for 700mm, 800mm and 900mm 3 kinds.

Hyper cabinet door: front door hole all for? 3 the round hole, improves the cabinet radiating performance and shielding performance.
Height can cooperate: 2 meters tracks, 1.8 meters tracks, 1.6 meters of cabinets.
Network cabinets include server rack, is also used to assemble, install panel, plug-ins, insert box, electronic components, devices and mechanical parts and components, make its make a whole installation box. Network cabinet is mainly used for wiring project, deposit router switch monitors with wire racks etc thing, engineering with more.. normally: network cabinets deep less or equal to, and server rack 800mm greater than or equal to the deep 800mm. Network cabinets should facilitate production, assembling, testing and package transportation. Server rack should conforms with the standardization, normalization, seriation requirements. Cabinet modelling beautiful, applicable, color coordination.
