Rack mount pc case function:
The use environment of rack mount pc case is generally harsh, with high temperature, low temperature, high humidity, long-term uninterrupted operation, and places with a lot of dust layer noise, so the protection requirements for rack mount pc case are very high. The industrial computer motherboard is mainly divided into two parts, the bottom plate + CPU card form. The current industrial pc cases can be divided into three categories, one is the mainstream embedded computer case, the other is the horizontal computer case, and the other is the wall-mounted pc case. The rack-mount computer case has the advantages of anti-extrusion, anti-corrosion, dust-proof, anti-vibration and anti-radiation.So what are the functions of the rack-mounted computer case?
1. The conductivity of the rack mount pc case: Whether the material of the case is conductive is a very important factor related to the safety of the computer accessories in the case. If the selected housing material is non-conductive, the generated static electricity cannot be conducted to the ground through the bottom shell of the housing, which will cause serious burnout of the hard disk and board in the housing. Nowadays, the material of the chassis is generally steel, and how to deal with the steel plate is the key to the internal structure of the chassis. The first is that we use galvanized sheets, which have very good conductivity in this case; the second is that only sprayed with anti-rust paint, and even some steel sheets that are only sprayed with ordinary paint have poor conductivity. In fact, it is very simple, as long as the measuring needle of the meter is placed on both sides of the case, if the indicator needle in the meter does not move, it means that the case is not conductive, and it is directly coated on the steel plate.
2. Thermal conductivity of the rack mount pc case: The rationality of the heat dissipation structure is an important factor related to whether the rack-mounted computer can run stably. High temperature is the killer of electronic products. Too high temperature will lead to system instability and accelerate the aging of parts. With the continuous improvement of the CPU main frequency of rack-mounted computers, the widespread use of high-speed hard disks and the frequent replacement of high-performance boards, the heat dissipation problem in the chassis has attracted more and more attention. So far, the most effective chassis cooling solution is to use an interactive cooling channel structure: the external cold air of the front chassis is sucked into the chassis from the 120mm high-speed ball fan ventilation holes on both sides of the hard disk frame and the chassis, and then sucked from the chassis, north-south The bridge chip, various boards, and the North Bridge finally reach the vicinity of the CPU. After passing through the CPU radiator, part of the hot air is discharged from the chassis through the fan outlets at the rear of the two 80mm chassis high-speed balls, and the other passes through a part of the fan box of the industrial computer power supply. . The case fan adopts a spherical fan, which has the advantages of large air volume, high speed, low heat generation, long life, low noise, avoiding excessive noise, and truly realizing "green" heat dissipation.
3. The shock resistance of the rack mount pc case: when the rack mount pc case is working, due to the chassis drive and the inside of the hard disk, vibration will occur when there are multiple fans at high speed, and the vibration can easily lead to wrong reading of the CD and hard disk The magnetic track is damaged and even data is lost, so the chassis is also one of our anti-vibration key structural design schemes. Considering the internal requirements of the shell, such as corrosion resistance, electrical conductivity and thermal conductivity, our shell damping system is all made of metal materials, which can not only meet the above requirements, but also play the role of anti-aging and heat resistance. Our shock absorption system solutions have been well received by domestic and foreign customers.
4. Electromagnetic shielding of rack mount pc case: Many people now know the damage of electromagnetic radiation to the human body, so everyone will try to choose a relatively small LCD display for electromagnetic radiation when purchasing a monitor. In fact, the industrial control host is working At the same time, the industrial control motherboard, industrial computer CPU, industrial computer memory and various motherboards will generate a large amount of electromagnetic radiation, which will cause certain damage to the human body if it is not prevented. At this point, the case has become an important weapon against electromagnetic radiation and protects our health. A good shielding box can also effectively block external radiation interference to ensure that the internal accessories of the computer are not affected by external radiation.
5. In order to increase the heat dissipation effect of the rack mount pc case, holes should be opened in the necessary parts of the case, including the side panel holes of the cabinet, the air inlet holes of the exhaust fan and the exhaust holes of the exhaust fan, so the shape of the holes must be Meet the technical requirements for radiation protection. The holes in the case should be as small as possible, and the strongest circular holes should be used to block radiation capabilities.
