The chassis generally includes a shell, a bracket, various switches on the panel, indicator lights, etc. The shell is made of a combination of steel plate and plastic with high hardness, which mainly protects the internal components of the chassis. The bracket is mainly used to fix the main board, power supply and various drives.

Cases are rarely noticed, and people only need to look good when choosing a case. But with the in-depth introduction of chassis technology, especially DIY users began to take the choice of chassis seriously. The hot sale of some brand-name high-end products illustrates this point. Therefore, many consumers now choose the chassis to look at the appearance first, and then focus on the material of the chassis, the interior space design, etc., so what aspects should be paid attention to when purchasing a chassis:

Heat dissipation

There are generally many circuits, CPUs, circuits, memory and disks inside the chassis that generate heat, which makes the server generate a lot of heat. Therefore, good heat dissipation is a prerequisite for an excellent chassis. The heat dissipation performance is mainly reflected in three aspects, one is the number and position of the fans, the other is the rationality of the heat dissipation channel, and the third is the selection of chassis materials. Good heat dissipation ensures the stable operation of the server. The case shell made of high-quality aluminum alloy or steel material with strong thermal conductivity can also effectively improve the heat dissipation environment.

redundancy

Some chassis may be in operation 24 hours a day, and the design industry for redundancy needs to be considered. The first is the redundancy of the cooling system. Generally, the chassis must be equipped with special redundant fans. When individual fans stop due to a fault, the redundant fans will take over immediately; the second is the redundancy of the power supply. When the main power supply fails due to a failure Or when the voltage is unstable, the redundant power supply can continue to supply power to the system; finally, the redundancy of the storage medium, the chassis has more hot-swappable hard disk positions, which can facilitate the hot maintenance of the server.

interior layout design

When designing the chassis, it is necessary to consider the influence of electromagnetic interference and heat between the internal components and devices of the chassis to improve the stability of electrical performance; it is necessary to pay attention to the strength and rigidity of the chassis to avoid deformation and cause poor electrical contact, doors, The connectors are stuck, or even damaged after being vibrated; corresponding measures must be taken according to the actual working environment and use conditions to improve the reliability and service life of the equipment.

Chassis sheet metal processing:

Through a series of operations such as shearing, cutting, bending or splicing of metal sheets, the desired shape is finally achieved. These processing techniques have relatively high technical requirements for operators. During processing, operations will be completed by means of shearing machines, punching machines, and CNC blanking. Therefore, operators must be proficient in various processing processes and equipment. Application and Input method of parameter information, etc.

Maintenance and cleaning of the chassis:

No matter what kind of product, the first step in maintenance is to clean it regularly. The chassis is also the case. Although the chassis has been surface treated to prevent rust and dust, it has been exposed to the air for a long time and contaminated with too much dust. It is neither beautiful nor conducive to the use of the chassis, so the maintenance of the chassis is very important.

Cleaning the case is an easy-to-use maintenance method:

    1. First, the surface of the sheet metal chassis needs to be rinsed with water to remove the dirt on the surface.

    2. Then add soap, liquid detergent or water with 5% ammonia solution to wipe.

    3. Rinse carefully with water again.

    4. Finally, we dry the water stains remaining on the surface of the cabinet. During the drying process, in order to wipe more cleanly, we need to wipe in the same direction. After wiping, we can let the surface dry naturally.

The paint layer on the surface of the chassis is very important for the protection of the chassis sheet metal. As long as the paint layer is not damaged, the sheet metal chassis can be used normally. Although the aging of the sheet metal chassis is irreversible, by frequent cleaning, we can delay this aging phenomenon.
