Liquid Immersion Cooling For Higher Power Density In Server Power Supplies

Focus:

The scaling of cloud-based Internet services and AI have driven growth of processing power in data centers. At the same time, the TCO for data centers is rising, increasing demand for highly efficient, reliable, and compact server systems. While fan cooling in server switch mode power supply (SMPS) racks is constrained by poor heat exchange through air, liquid cooling more effectively exchanges the racks’ heat outside the data center without wasting a significant share of the energy on cooling. This article presents the findings from a recent (experimental) study that validates the potential benefits of immersion cooling for a server SMPS. They emphasize system re-design to capture the highest value of immersion cooling, improving energy efficiency, power density and reliability. Two real world use cases are also presented that demonstrate the benefits of liquid cooling at the server power supply and data center levels.

What you’ll learn:

• How to understand the principles of two-phase immersion cooling and the power supply efficiency benefits of liquid cooling versus forced-air cooling over a range of power density levels
• How to understand the performance benefits of liquid immersion cooling at both the server power supply and data center levels
