With the development of data center cooling technology

air-liquid hybrid cooling with liquid cooling for high-power components and air cooling for other components

has become one of the main development directions The comparative study of component-level energy consumption between the air-liquid hybrid cooling method and the traditional cooling method is of great significance for further optimizing the cooling performance and tapping the energy-saving potential of the air-liquid hybrid cooling method. This paper establishes a data center energy utilization model

introduces in detail the key components of the server and cooling system and the one- and three-dimensional coupling modeling method

and discusses in depth the system energy consumption differences between server air cooling and hybrid cooling. Air cooling represents the traditional cooling method

and hybrid cooling is a new type of cooling method that combines air and liquid. Given the same server component size

chip power

and chip maximum temperature

the results of the two cooling methods are compared and analyzed to quantify the difference in energy consumption. The comparison results show that compared with traditional air cooling

hybrid cooling has very obvious energy-saving effects in the refrigeration compression link of the chiller and the power consumption of the server water pump. In addition

since there is no air-water heat exchanger in the liquid cooling system of hybrid cooling

it not only simplifies the system

but also further improves the heat transfer efficiency of the first cooling side and the secondary cooling side of the data center. The air-liquid hybrid cooling has obvious advantages in reducing energy consumption.
