Description

[0001] The present invention relates to the field of data center evaporative cooling technology, specifically to a fully natural cooling data center indirect evaporative cooling cooling cooling system. Background [0002] Traditional data centers usually use frozen water circulation and mechanical refrigeration to dissipate heat in the data center, which has a large power consumption in all seasons and encounters bottlenecks in energy efficiency improvement; At present, the use of natural cooling has direct fresh air cooling and indirect evaporative cooling, direct fresh air cooling due to the dust impurities contained in the fresh air, a long time can cause great pollution to the server, resulting in reduced server performance, and the current mainstream indirect evaporation cooling equipment can not meet the cooling needs of the data center throughout the year, summer still need mechanical refrigeration assistance; However, in theory, with the gradual maturity of the application ...

Problems solved by technology

[0002] Traditional data centers usually use chilled water circulation and mechanical refrigeration to dissipate heat in the data center. This method consumes a lot of power in four seasons and encounters bottlenecks in energy efficiency improvement. Currently, natural cooling includes direct fresh air cooling and indirect evaporative cooling. Due to the dust and impurities mixed in the fresh air, direct fresh air cooling can cause great pollution to the server for a long time, resulting in a decrease in server performance. However, the current mainstream indirect evaporative cooling equipment cannot meet the cooling needs of the data center throughout the year, and mechanical refrigeration is still required in summer. auxiliary; but theoretically speaking, with the gradual maturity of the application of indirect evaporative cooling technology, in some low-temperature and dry northern regions such as Northwest China and Inner Mongolia, the data center can meet the annual cooling demand only by using indirect evaporative cooling; the present invention is Research on improving the efficiency of indirect evaporative cooling to achieve year-round free cooling
