Hard disk rack, optical drive rack: There are generally two types of hard disk racks, one is a split type and the other is a compression card type.
High-quality chassis generally have metal spring anti-vibration function; the number of installed hard disks is generally from 4 to 15;
Backplane: There are many specifications of the backplane; mainly divided by the specifications of the motherboard. Ordinary motherboards can generally be installed; a chassis with a length of less than 520mm cannot be installed with a 12*13 dual-to-strong motherboard, and a chassis with a length of 520mm can be installed.
Clamping strip: mainly plays a fixed role. When installing a video long card with security monitoring, or an industrial CPU long card, the long card must be fixed to avoid shaking and looseness during use.
Rear slot expansion: There are 7 slots or 14 slots; the main purpose of the 14-slot backplane is to install multi-channel video cards. For example, for some large-scale surveillance systems, 64 channels or 128 channels must be replaced. 14-slot backplane;
The heat conduction of the industrial control cabinet: the rationality of the heat dissipation structure is an important factor related to the stable operation of the computer.
Shock resistance of industrial control chassis: When the industrial control chassis is working, the optical drive, hard disk, and multiple fans in the chassis will vibrate when running at high speed, and vibration can easily lead to misreading of optical discs, damage to hard disk tracks and even data loss. Therefore, the seismic resistance of the chassis is also a key structural design scheme of the chassis.
The electromagnetic shielding of the industrial control chassis: When the host is working, the motherboard, CPU, memory and various boards will generate a large amount of electromagnetic radiation. If it is not prevented, it will cause some harm to the human body. At this time, the case becomes an important line of defense to shield electromagnetic radiation and protect health.
A well-shielded chassis can also effectively block external radiation interference and ensure that the internal components of the computer are not affected by external radiation. In order to increase the heat dissipation effect of the industrial control case, the necessary parts of the case will have holes, including the side plate holes of the box, the air inlet holes of the exhaust fan and the exhaust fan exhaust holes, etc., so the shape of the hole must conform to the technology that can block radiation. Claim. The openings on the chassis should be as small as possible, and round holes with strong radiation blocking ability should be used as much as possible. Secondly, pay attention to the electromagnetic shielding of the wiring of various indicators and switches. Longer connecting wires need to be designed as twisted wires, and the bare welded metal parts at both ends of the wires must be wrapped with rubber sleeves, so as to avoid electromagnetic radiation generated by the electrical circuits in the chassis.
