TOPPER

Enclosures are freestanding or self-supporting enclosures used to house electrical or electronic equipment. Cabinets are generally configured with doors, removable or non-removable side panels and back panels. The cabinet is an integral part of the electrical equipment and is the carrier of the electrical control equipment. It is generally made of cold-rolled steel or alloy. It can provide protection against water, dust, electromagnetic interference and other protective effects on stored equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets and so on.

Enclosures are freestanding or self-supporting enclosures used to house electrical or electronic equipment. Cabinets are generally configured with doors, removable or non-removable side panels and back panels. The cabinet is an integral part of the electrical equipment and is the carrier of the electrical control equipment. It is generally made of cold-rolled steel or alloy. It can provide protection against water, dust, electromagnetic interference and other protective effects on stored equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets and so on.

  Many people see the cabinet as a cabinet used to hold IT equipment. Cabinet is a cabinet, but not only so. For the computer itself, the cabinet also has and UPS power supply important auxiliary role. A good cabinet means ensuring that the computer can run in a good environment. Therefore, the role played by the cabinet is equally important. The cabinet systematically solves the computer application of high-density heat dissipation, a large number of cable attachment and management, high-capacity power distribution and full compatibility with different manufacturers of rack-mounted equipment problems, so that the data center can run in a highly stable environment. Various styles of cabinets can be seen in major server rooms, and as the computer industry continues to make breakthroughs, the functions embodied in cabinets are becoming larger and larger. Cabinets are generally used in network cabling rooms, floor wiring rooms, central server rooms, data rooms, control centers, monitoring rooms, monitoring centers, etc.

  Common cabinet colors are white, black and gray. (which is divided into many types, such as orange grain, fine sand grain, etc.); cabinets by material, there are aluminum profile cabinets, cold-rolled steel plate cabinets, hot-rolled steel plate cabinets; according to the processing process, there are nine-fold profile cabinets and sixteen-fold type of cabinets, etc.. The type of plate, coating material, processing technology determines the stability of the cabinet. Generally its length specification is 600,800mm, width specification is 600,800,1000mm, height specification is 42U,36U,24U. Most of the cabinets used in the early days are made of castings or angles by screws, rivets or welding into the cabinet frame, and then add the cover made of thin steel plate (door). This cabinet is large, bulky, rudimentary appearance, has been eliminated. With the use of transistors, integrated circuits and various components of the ultra-miniaturization, the structure of the cabinet also to miniaturization, the direction of the development of the building blocks. Cabinet has developed from the past whole panel structure into a certain size series of plug-in boxes, plug-in structure. Insert box, plug-in assembly arrangement is divided into horizontal arrangement and vertical arrangement of the two categories. Cabinet materials are commonly used thin steel plate, a variety of cross-sectional shape of steel profiles, aluminum profiles and a variety of engineering plastics. In addition to the framework of the cabinet with welding, screw connection, but also using the bonding process. Cabinet according to the components of the load-bearing, materials and their different manufacturing processes, can be divided into profiles and thin plate two basic structures. ① Profile structure cabinet: there are two kinds of steel profile cabinets and aluminum profile cabinets. Steel profile cabinets are composed of profiled seamless steel tubes as columns. This cabinet has good rigidity and strength, and is suitable for heavy equipment. Aluminum profile cabinets composed of aluminum profiles have a certain degree of rigidity and strength, and are suitable for general or light equipment. This kind of cabinet is light in weight, less processing and beautiful in appearance, and is widely used. ②Thin plate structure cabinet: the whole plate type cabinet, its side plate for a whole steel plate bending forming. This cabinet stiffness and strength are better, suitable for heavy or general equipment. But because the side plate is not removable, so that assembly, maintenance is not convenient. Bending plate column type cabinet structure and profile cabinet similar, and column is bent from the steel plate. This cabinet has a certain degree of rigidity and strength, suitable for general equipment. According to the needs of the cabinet is also equipped with cabinet accessories. Its main accessories are fixed or retractable guide rails, locking devices, hinges, alignment slots, alignment frames and shielding comb reeds, etc.
