Liquid cooling industry standard will be implemented soon
According to the official news of China information and Communication Research Institute, five data center liquid cooling industry standards have been released in December 2021 and will be officially implemented from April 1, 2022.
It is understood that this series of industrial standards covers the technical requirements and test methods of immersion, cold plate and other main liquid cooling methods, as well as the requirements and test methods of liquid cooling energy efficiency, cooling liquid technical requirements and test methods, filling the gap in the current industrial standards of liquid cooling in data centers at home and abroad.
The Institute pointed out that since the liquid cooling of data center is a newly emerging "revolutionary" technology, the research and development of liquid cooling of enterprises is basically in a state of their own. The release of this series of industry standards has important guiding significance for the application of liquid cooling technology in enterprises and the orderly construction of liquid cooling industry in China.
What is liquid cooling:
Liquid cooling refers to the cooling method that uses the liquid with high specific heat capacity as the working medium for heat transmission to meet the heat dissipation needs of IT equipment such as servers. It is mainly divided into indirect contact liquid cooling and direct contact liquid cooling. Purified water, mineral oil and fluorinated liquid are commonly used coolants.
At present, liquid cooling technology is mainly used in high-performance computing, widely used in data center, edge computing, artificial intelligence technology and so on.
Benefits of liquid cooling:
With the innovative development of cloud computing, big data, especially artificial intelligence technology, data centers that undertake a large number of data computing and storage need to be more efficient to meet the needs of business development. In solving the heat dissipation problem of high heat density data center, liquid cooling has incomparable advantages over the air conditioning system of traditional data center, and the energy consumption is lower.
Compared with the published data center of pue.05, the utilization rate of liquid cooling system is much lower than that of the traditional liquid cooling system. Compared with pue = 1.3-1.5 in the data center of air cooling system, its energy efficiency results are very significant.
According to the analysis of the report, more than 20% of edge computing data centers will adopt liquid cooling technology in the future. Due to its high efficiency, low dependence on buildings and quiet safety, liquid cooling technology can meet the deployment of higher density under the condition of insufficient power capacity.
