Embodiment

[0050] According to the requirements of relevant national standards and specifications, the data center is subjected to electromagnetic shielding treatment. The electromagnetic shielding indicators are as follows:

[0051] The shielding effectiveness index of the electromagnetic shielding system is shown in the following table:

[0052]

[0053]

[0054] The invention designs the electromagnetic shielding system from the prevention of the interference of external electromagnetic waves and the leakage of information, so as to meet the requirements of the above shielding index.

[0055] Such as figure 1 As shown, the radiated electromagnetic wave projected on the metal plate will be reflected and attenuated;

[0056] The calculation formula of shielding effectiveness is: SE=R+A;

[0057] In the formula: SE——shielding effectiveness (dB);

[0058] R——reflection loss (dB);

[0059] A - absorption loss (dB);

[0060] The reflection loss R can be calculated by the following ...

Abstract

The invention relates to the technical fields of heating and ventilation and electromagnetic shielding, and specifically discloses a data center with a high-low-frequency electromagnetic shielding function. The data center comprises a high-low-frequency electromagnetic shielding cabinet used for shielding high-low-frequency electromagnetic radiation, multiple groups of servers arranged in the high-low-frequency electromagnetic shielding cabinet, and an electrical grounding assembly used for grounding and eliminating static electricity; and one end of the electrical grounding assembly is electrically connected with the high-low-frequency electromagnetic shielding cabinet. By virtue of matching between a high-low-frequency shielding dual-Faraday cage and a dual-Faraday cage electrical short-circuit connection assembly, and by combination with an anti-electromagnetic-radiation door structure, the static generated by electromagnetic radiation is guided into the ground through the groundingapparatus to shield the high-low-frequency electromagnetic radiation, thereby greatly improving electromagnetic safety protection capability on the data center; by virtue of the cooling equipment, the high-low-frequency electromagnetic shielding cabinet has a temperature adjustment function; and in addition, the data center is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of HVAC and electromagnetic shielding, in particular to a data center with high and low frequency electromagnetic shielding functions. Background technique [0002] The basic principle of the shielded data center comes from the Faraday cage design. Without shielding, our servers will be affected by lightning discharge or indirect man-made strong electromagnetic interference sources, which will cause the servers to fail to work or be damaged. Specific protective measures: use electromagnetic shielding structure and reliable grounding, thus forming an equipotential body, blocking external electromagnetic interference, and blocking electromagnetic waves generated by internal servers, which can shield electromagnetic interference. However, most of the electromagnetic shielding technologies in existing data centers are iron-plate sealed structures that are effective for low frequencies, which have low shielding e...
