A freestanding or self-supporting enclosure used to house electrical or electronic equipment. Cabinets are generally equipped with doors, removable or non-removable side panels and back panels.

The cabinet is an indispensable part of electrical equipment and is the carrier of electrical control equipment. It is generally made of cold-rolled steel plates or alloys. It can provide waterproof, dustproof, and electromagnetic interference protection for the stored equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.

Equipment use

Many people think of cabinets as cabinets for IT equipment. Cabinets are cabinets, but they are more than that. For computers themselves, cabinets also play an important auxiliary role with UPS power supplies. 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 problems of high-density heat dissipation, large-scale cable attachment and management, large-capacity power distribution, and full compatibility with rack-mounted equipment from different manufacturers in computer applications, so that the data center can operate in a highly stable environment.

In all major computer rooms, you can see various types of cabinets. With the continuous breakthroughs in the computer industry, the functions of cabinets are becoming more and more powerful. Cabinets are generally used in network wiring rooms, floor wiring rooms, central computer rooms, data computer rooms, control centers, monitoring rooms, monitoring centers, etc.

Basic structure

Common cabinet colors include white, black and gray. (There are many types of cabinets, such as orange grain and fine sand grain.) Cabinets are divided into aluminum cabinets, cold-rolled steel cabinets, and hot-rolled steel cabinets according to the material. Cabinets are divided into 90% profile cabinets and 160% profile cabinets according to the processing technology.

The type of plate, coating material, and processing technology determine the stability of the cabinet. Generally, its length specifications are 600, 800mm, width specifications are 600, 800, 1000mm, and height specifications are 42U, 36U, 24U. Most of the cabinets used in the early days were made of castings or angle steel connected or welded into cabinet frames by screws, rivets, and then covered (doors) made of thin steel plates. This type of cabinet is large, bulky, and has a simple appearance, and has been eliminated. With the use of transistors and integrated circuits and the ultra-miniaturization of various components, the structure of the cabinet has also developed in the direction of miniaturization and building blocks. The cabinet has developed from the whole panel structure in the past to a plug-in box and plug-in structure with a certain size series. The assembly and arrangement of plug-ins and plug-ins are divided into two categories: horizontal arrangement and vertical arrangement. Cabinet materials generally use thin steel plates, steel profiles of various cross-sectional shapes, aluminum profiles, and various engineering plastics. In addition to welding and screwing, the frame of the cabinet also uses bonding technology.

Cabinets can be divided into two basic structures: profiles and thin plates, depending on the load-bearing capacity, materials and manufacturing processes of the components.

①Profile structure cabinet: There are two types of cabinets: steel profile cabinets and aluminum profile cabinets. Steel profile cabinets are composed of special-shaped seamless steel pipes as columns. This cabinet has good rigidity and strength and is suitable for heavy equipment. Aluminum profile cabinets composed of aluminum alloy profiles have certain rigidity and strength and are suitable for general or light equipment. This cabinet is light in weight, requires less processing, and has a beautiful appearance, and is widely used.

② Thin plate structure cabinet: The side panel of the whole plate cabinet is formed by bending a whole piece of steel plate. This cabinet has good rigidity and strength and is suitable for heavy or general equipment. However, since the side panel cannot be disassembled, it is inconvenient to assemble and repair. The structure of the bent plate column cabinet is similar to that of the profile cabinet, but the column is made of bent steel plate. This cabinet has a certain rigidity and strength and is suitable for general equipment.

The cabinet is also equipped with cabinet accessories according to needs. Its main accessories include fixed or retractable guide rails, locking devices, hinges, wiring troughs, wiring racks and shielding comb springs.

Skills requirement

(1) It should have good technical performance. The cabinet should be resistant to vibration, impact, corrosion, dust, water, and radiation, so as to ensure that the equipment can work stably and reliably.

(2) It should have good usability and safety protection facilities, be easy to operate, install and maintain, and ensure the safety of the operator.

(3) It should be easy to produce, assemble, debug, package and transport.

(4) It should meet the requirements of standardization, specification and serialization.

(5) Beautiful shape, practicality and coordinated colors.

Equipment Classification

With the development of computer and network technology, cabinets are becoming an important part of it. IT facilities such as servers and network communication equipment in data centers are developing in the direction of miniaturization, networking, and racking. Cabinets are gradually becoming one of the protagonists in this change. Common cabinets can be divided into the following categories:

By function: fireproof and antimagnetic cabinets, power cabinets, monitoring cabinets, shielding cabinets, safety cabinets, waterproof cabinets, safes, multimedia consoles, filing cabinets, wall-mounted cabinets

By application scope: outdoor cabinets, indoor cabinets, communication cabinets, industrial safety cabinets, low-voltage distribution cabinets, power cabinets, server cabinets

Extended categories: console, computer case cabinet, stainless steel case, monitoring console, tool cabinet, standard cabinet, network cabinet

Cabinet panel requirements

1. Cabinet panels: The industry requires that standard cabinet panels should be made of high-quality cold-rolled steel plates. Many cabinets on the market are not made of cold-rolled steel, but are made of hot plates or even iron plates, which are prone to rust and deformation. Please identify them carefully!

Cold-rolled steel plate. Cold-rolled steel plate is a steel plate produced by cold rolling, commonly known as cold plate. Compared with hot-rolled steel, the thickness of cold-rolled steel plate is more precise, and the surface is smooth and beautiful. At the same time, it also has various superior properties, especially in terms of processing performance. High-quality cold-rolled steel plate can ensure the long-term toughness and load-bearing performance of the cabinet. Cold-rolled steel plates are widely used in home appliances such as automobiles, refrigerators, washing machines, as well as industrial equipment and various building materials. Cold plate surface: The surface of cold-rolled steel plate is smooth and beautiful, smooth and delicate to the touch, full of toughness and steel strength, highlighting the noble quality of the cabinet!

2. Regarding the thickness of the plate: the industry generally requires: the standard thickness of the cabinet plate is 2.0MM for the column, 1.2MM for the side plate and the front and rear doors (the industry requires the side plate to be more than 1.0MM, because the side plate does not bear the load, so the plate can be slightly thinner to save energy), and the fixed tray is 1.2MM. The columns of Huaan Zhenpu cabinets are all 2.0MM thick to ensure the cabinet’s load-bearing capacity (the columns play the main load-bearing role).

Full mesh front door: The front door of the cabinet is all made of ?3 round holes, which improves the heat dissipation and shielding performance of the cabinet.

The height can be matched: 2.0m cabinet, 1.8m cabinet, 1.6m cabinet.

Network cabinets include server cabinets, and are also used to combine installation panels, plug-ins, plug-in boxes, electronic components, devices, and mechanical parts and components to form an integrated installation box. Network cabinets are mainly used in wiring projects, storing routers, switches, monitors, wire racks, etc., and are used more in projects. Generally speaking: the depth of a network cabinet is less than or equal to 800mm, while the depth of a server cabinet is greater than or equal to 800mm. Network cabinets should be easy to produce, assemble, debug, and package and transport. Server cabinets should meet the requirements of standardization, specification, and serialization. The cabinets are beautiful, practical, and color-coordinated.
