Microsoft Immerses The Server in A Liquid For Better Heat Dissipation

         Microsoft puts the server into "water" to improve its performance and energy efficiency. The cooling principle is to immerse the server rack in a specially designed non-conductive liquid completely . when this liquid is directly impacts the components, the heat is discharged, the liquid reaches a lower boiling point (50 ℃) and condenses, and falls back into the tank as a deluge liquid. Because no energy is needed to move the liquid around the tank, and the condenser does not need a cooler, a closed-loop cooling system is created to reduce the cost.

        This liquid cooling method has been used by cryptominers to mine bitcoin and some other cryptocurrencies in recent years. This approach has inspired Microsoft to try to use it in the past few years to test the peak demand of cloud and the intensive workload of applications such as machine learning. Microsoft previously sank the entire data center to the bottom of Scotland, and 864 servers and 27.6 Pb of storage space were put into the water. The experiment is successful, and the failure rate is only one eighth of that of the land data center.

      Considering the growth trend of global power use, Microsoft's efforts to solve the energy problem will be a very challenging work, but if it can be popularized more widely, projects such as two-stage immersion method will certainly help. Microsoft's goal is to achieve zero water consume cooling.

     We believe that liquid cooling system is still one of the best solutions in the thermal industry ,and with the power consumption of electronic equipment continues to increase, the problem of heat dissipation will be more and more worthy of our attention.
