Totally-sealed normal-temperature self-circulating energy-saving mute special server case

Abstract

The invention discloses a totally-sealed normal-temperature self-circulating energy-saving mute special server case. A cold air internal loop, a hot air internal loop and at least two brackets are arranged in the case; side edges of two sides of each bracket are hermetically fixed to the inner wall of the totally-sealed case, and gaps are formed between another two side edges of the bracket and the inner wall; the cold air internal loop and the hot air internal loop consist of spaces between the gaps and the two brackets; the totally-sealed case is provided with a heat exchanger; the heat exchanger communicates with the cold air internal loop and the hot air internal loop; and the heat exchanger is provided with a fan. According to the case, sealed cooling is realized, so that the reliability of a server is greatly improved.

Description

technical field [0001] The invention belongs to the field of electronic information equipment, and in particular relates to a fully sealed room temperature self-circulation energy-saving and silent special server case. Background technique [0002] Existing cooling technology for rack-mounted servers generally adopts air-cooling technology, which draws air in from the front of the server chassis and exchanges heat through the main heat-generating components of the server. The refrigerated air undergoes secondary heat exchange. The main problems of air cooling technology: 1. High energy consumption. The server has built-in 6~8 high-power fans for ventilation. The power of a single fan is about 10~12 watts, and the total power is about 80~100 watts, accounting for one-third of the total power of the server. One; 2. The noise is high, the fan speed is 5000~15000 rpm, and the noise is generally above 80dB; 3. The dust pollution is serious, and the fan rotates to make the air in...

AI Technical Summary

Problems solved by technology

The main problems of air cooling technology: 1. High energy consumption. The server has built-in 6~8 high-power fans for ventilation. The power of a single fan is about 10~12 watts, and the total power is about 80~100 watts, accounting for one-third of the total power of the server. One; 2. The noise is high, the fan speed is 5000~15000 rpm, and the noise is generally above 80dB; 3. The dust pollution is serious, and the fan rotates to make the air in the computer room flow quickly, resulting in a large amount of dust and charged particles and flow; 4. The electromagnetic pollution is serious, the rotation of the fan generates a large amount of electromagnetic waves, and the operation of the server itself also generates a large amount of electromagnetic waves, and the non-fully enclosed chassis has no shielding effect; Stability of server use; 6. Influenced by non-thermal faults, due to the influence of dust or insects, non-thermal faults such as internal short circuits in the server are serious; 7. High operating costs, one-third of the power in the server is used for fan operation, and in the computer room It also needs to be equipped with a special air conditioner for cooling, and the operating cost is very high

Main technical issues: 1. Selection of evaporative cooling medium; 2. Design of closed chassis; 3. Material of chassis; 4. Condensation and self-circulation system after vaporization; 5. Connection of server external ports
