The purchasing skill of computer anti-radiation chassis

Computer radiation on human harm is obvious, and the basic way to prevent radiation is to choose a radiation-proof chassis, this article gives you how to buy radiation-proof chassis and some skills experience.

1, Chassis materials: selection of imported galvanized steel sheet material, thickness should be more than 1mm, the surface has an electrolytic layer protection, this material has a fingerprint, not rust characteristics, and can absorb electromagnetic radiation.

2, the production process: in order to ensure a good chassis heat dissipation, generally in the box to open a number of cooling holes. There is a misunderstanding, the need for consumer attention, many people think that the chassis cooling hole more the better, the reason is conducive to heat dissipation. In fact, the box openings too much, will lead to the leakage of electromagnetic radiation. Therefore, when the manufacturer designs the chassis, the size of the hole and the linear size is a very important link. Theoretically, the ideal aperture size is R/30 (r), which can not only take care of the cooling demand of the chassis, but also effectively prevent the diffraction of electromagnetic waves.

3, the sealing of the chassis: how to ensure that the chassis of the heat dissipation, but also shielding off electromagnetic radiation, this is the case of the high sealing requirements. This point, the first-line brand chassis manufacturers of the advantages of the embodiment, only with strong financial strength, to provide excellent mold research and development, design ability to ensure the precision of the mold, and high precision, high sealing mold is to ensure that the chassis sealing the prerequisite conditions. In contrast, the kitchen chassis manufacturers in order to pursue efficiency, by saving expensive tooling costs, to reduce the cost of production, which is inferior chassis can sell low price still have profit of one of the most important reasons.

4, EMI Certification: EMI certification and 3C certification, the current domestic evaluation of the PC's important environmental protection and performance indicators. Computer work, the chassis components generated by electromagnetic waves and electronic components, resulting in interference, known as EMI (Electromagnetic interference), as the TV screen on the common "snowflake" phenomenon, that is to say that the television received the signal was disturbed. Chassis manufacturers are designed to consider how to achieve electromagnetic compatibility (electromagnetic compatibility, abbreviation for EMC), means that electronic equipment does not interfere with other equipment, but also not affected by other devices; The best measure is to provide EMI with a good grounding way, Release EMI. Therefore, whether to pass EMI Test, is also our choice of chassis an important standard.

The above mentioned prevention measures chassis, only with the strength of the big manufacturers will do so meticulous, and its product quality is also a brand-name manufacturers can not be compared to spoke.

Finally remind everyone to stay away from electromagnetic radiation pollution, of course, prevention is the most critical, such as the computer as far as possible in the living room, away from the bedroom, the impact of electromagnetic radiation on large groups such as children, pregnant women to minimize the use of computer time. For those who need to use the computer daily work, but also to improve the awareness of self-care, especially to strengthen physical exercise. Only the correct handling of the relationship between work and rest, to develop a regular life habits, so that the body can recuperate, to have sufficient energy, and this is to ensure the basis of high efficiency work level!
