Evaporative cooling air-conditioning system for data center based on air-cooling and water-cooling composite unit

Abstract

The invention discloses an evaporative cooling air-conditioning system for a data center based on an air-cooling and water-cooling composite unit. The system comprises a water-side evaporative coolingunit, an air-side evaporative cooling unit and a data center machine room unit communicated with the air-side evaporative cooling unit, wherein the data center machine room unit is connected with thewater-side evaporative cooling unit through a secondary-side liquid supply pipe and a secondary-side liquid return pipe, and a secondary-side circulating water pump is arranged on the secondary-sideliquid supply pipe. According to the air-conditioning system, the air side evaporative cooling technology and the water side evaporative cooling technology are effectively combined together, room-level cooling is conducted on a data center in an air cooling mode, chip-level cooling is conducted on a chip of a server in a water cooling mode, and therefore, energy consumption of the data center is reduced.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning systems, and in particular relates to an evaporative cooling air-conditioning system for data centers based on an air-cooled and water-cooled composite unit. Background technique [0002] With the rapid development of new technologies such as artificial intelligence, cloud computing, big data, and 5G, data centers serve as service platforms for centralized processing, transmission, storage, and exchange of data information. The number of data center constructions is growing exponentially. At the same time, based on the surge in market demand, IT computing power continues to evolve, and the power of CPUs and servers continues to increase. Data centers are bound to develop towards high density. Currently, the average power of a single cabinet in a data center is 6 ~8KW, it is expected that 15~20KW / cabinet will become the mainstream in the future, so the power consumption of the data center ...

AI Technical Summary

Problems solved by technology

[0003] Facing the high energy consumption of data center air-conditioning systems, the existing cooling methods include air cooling and water cooling, but the disadvantages of traditional air cooling cooling methods are the small specific heat capacity of air and low thermal conductivity, which lead to high energy consumption in transportation and large temperature difference in heat transfer. It is not conducive to the heat being taken away in time, and it has gradually been unable to meet the heat dissipation and cooling needs of computer equipment, and the equipment of the air conditioning system occupies a large amount of space in the data center where "everything is expensive"; and when the traditional cold water system is used as the cooling of the data center The solution is huge and complex, and it is not conducive to the utilization of natural cold sources. It is also difficult to operate and maintain in the later stage, and it requires a lot of power consumption.
