Abstract:
The requirement for data center facilities is keeping increasing for the development of artificial intelligence, machine learning, 5G technologies, internet of things, data mining, etc. The modern data centers nowadays are demanded for high performance. It results in high-density and high flux heat release. The lower power usage effectiveness (PUE) in the data center systems is attracting more attention. The most commercialized data centers are based on the convective air cooling. However, the relatively low specific heat limits the further reducing on the PUE below 1.5 in most conditions. Thus, it is expected on the development of new cooling technologies for future applications. Liquid immersion cooling is one of the emerging cooling technologies for data centers. In the talk, we will compare the two-phase immersion cooling with single-phase immersion cooling. It is shown the two-phase cooling use the latent heat to enhance the heat transfer can reduce the PUE below 1.1. The enhanced heat transfer for the two-phase immersion cooling with the substrate modification and with the combination of impingement will be further analyzed.
