Advantages of Liquid Cooled Data Center over Traditional Data Center?

Efficient heat dissipation: traditional data centers mostly use air cooling, air heat capacity is small, poor thermal conductivity, it is difficult to quickly take away a large amount of heat. Liquid-cooled data centers use liquid as the cooling medium, which has a large heat capacity and high thermal conductivity, and can absorb and transfer the heat generated by servers and other equipment more efficiently, and can raise the water temperature of the server outlet to more than 40 degrees Celsius, which significantly improves the cooling effect, ensures that the equipment operates in a more stable temperature environment, and reduces the risk of performance degradation and malfunction caused by overheating.

Remarkable energy saving effect: On the one hand, the liquid cooling system can control the temperature more accurately, reducing the energy waste caused by over-cooling of traditional air-cooled systems. On the other hand, liquid-cooled data centers can make use of the natural cold source for a longer period of time. For example, in winter or cold regions, the coolant can be cooled directly by using cold outdoor air through dry coolers and other equipment, which significantly reduces the energy consumption of the cooling system. According to statistics, liquid-cooled data center PUE (the ratio of total data center energy consumption to IT equipment energy consumption) can be as low as 1.2 or less, compared with traditional air-cooled data centers (PUE is usually between 1.5 - 2.0), the energy-saving effect is obvious.

Improved space utilization: air-cooled systems require a large number of air conditioning equipment and ventilation ducts to achieve air circulation, taking up more space in the server room. Liquid-cooled systems, on the other hand, are relatively compact and do not require large-scale ventilation facilities, saving about 30% - 50% of the server room space, enabling the data center to deploy more servers and IT equipment in the limited space, improving the space utilization rate and the overall operational efficiency of the data center.

Reducing noise pollution: The air conditioning system and fans of traditional air-cooled data centers usually need to run at high speeds to ensure the cooling effect, which generates a large amount of noise, generally around 60 - 70 decibels, which has a certain impact on the environment of the server room and the health of the staff. Liquid cooling system operation is mainly circulating pumps and other equipment operation, the noise is relatively small, usually in 40 - 50 dB or so, can create a more quiet and comfortable working environment for the staff.

Extend the service life of the equipment: liquid cooling system can provide a more stable and uniform temperature environment for servers and other equipment, avoiding the aging and damage of equipment parts due to local overheating, which helps to extend the service life of the equipment. Research has shown that the incidence of hardware failure of servers and other equipment can be reduced by more than 50% in a suitable temperature environment, thus reducing the cost of equipment replacement and maintenance and improving the overall reliability of the data center.

Adaptation to high-density deployment: With the development of data centers, the computational density of servers continues to increase, generating more and more heat. Traditional air-cooled cooling methods often struggle to meet the demand for heat dissipation when dealing with high-density server deployments. Liquid cooling technology can better adapt to the requirements of high-density deployment, providing effective cooling solutions for high-density data centers and ensuring the stability and performance of equipment under high load operation.
