Hello, everyone, today we are going to introduce the relevant knowledge about liquid cooled data centers, and I hope that this video will be very helpful for you to understand liquid cooled data centers.
First of all, the liquid-cooled data center refers to the data center that applies liquid cooling technology and liquid cooled servers and other equipment.
Compared with traditional air-cooled servers, the heat export mode of liquid-cooled servers is different. In general, the industry divides liquid cooling into direct cooling and indirect cooling. At present, direct cooling is mainly based on submerged liquid cooling technology, which can be divided into phase change and non-phase change, and indirect cooling is mainly based on cold plate liquid cooling technology. Submerged liquid cooling technology is a kind of cooling technology that uses liquid as the heat transfer medium, the heating device is immersed in the liquid, and the heat exchange is carried out by direct contact. The cold plate liquid cooling refers to the non-contact liquid cooling technology that uses liquid as a heat transfer working medium to flow in the internal flow channel of the cold plate and cools the heat source through heat transfer.
So what are the advantages of a liquid-cooled data center?
01 The efficient cooling of liquid cooling technology can effectively improve the efficiency and stability of the server. IT can achieve efficient cooling of various equipment. At the same time, due to the large specific heat capacity of the liquid, its own temperature will not change significantly after absorbing a lot of heat, so it can stabilize the CPU temperature and ensure that the CPU will not overclock in a certain range.
02. The application of liquid cooling technology helps to achieve energy saving and noise reduction in data centers. Compared with the traditional air-cooled data center, the air-cooled infrastructure of the air conditioning system is removed, and the circulating pump is increased, which can save the construction cost. Secondly, it can effectively reduce the energy consumption ratio, which can reduce the PUE to 1.05, meeting the requirements of green data centers.
03 The application of liquid cooling technology helps to improve the server density per unit space of the data center, and greatly improves the computing efficiency of the data center. The cooling capability of liquid cooling technology is good enough to cope with the cooling work of high power density data centers
04. Liquid cooled servers can ignore environmental impacts such as altitude and region. Compared with air, the specific heat capacity of liquid-cooled liquid is not affected by altitude and air pressure, and can still maintain a high heat dissipation efficiency, ensuring the operation efficiency and performance of data centers at high altitudes.
05. Waste heat from liquid cooled data centers can create economic value. The heat of the liquid-cooled data center is based on the liquid as the carrier, which can be directly connected to the building heating system and water supply system through heat exchange to meet the heating and warm water supply needs of nearby residents. It not only saves energy, but also creates added value for the data center.
Finally, let's look at the future development trend of liquid cooled data centers:
In the future, the data center temperature control market will appear a new pattern of integrated development of "air cooling + liquid cooling".
Air cooling technology will not be completely replaced by liquid cooling technology, and customers will choose different data center cooling solutions according to different needs. For data centers with lower single-cabinet power, customers still choose air-cooled cooling. For high-density large-scale computing needs such as supercomputing and energy exploration, comprehensive consideration of cost factors, flexible choice of cold plate and immersed mixed liquid cooling, some parts and equipment with high power consumption to switch to liquid cooling solutions will also become popular.
Secondly, China's liquid-cooled data centers are evolving toward high efficiency. The integration of AI technology will accelerate the process of intelligent operation and maintenance replacing human operation and maintenance, so as to achieve comprehensive monitoring of the complex liquid cooling ecosystem, accurate control of faults, and improve the operation and operation efficiency of the data center.
Finally, according to relevant forecasts, in 2025, the market size of China's cold plate liquid cooled data center will reach 78.49 billion yuan, and the submerged type will reach 54.54 billion yuan; Submersible liquid cooled data centers with its excellent cooling effect, the market share will achieve rapid growth.
