Thermal resistance is a key consideration when selecting a cooling system. AHRAE recentlyreported (1) that thermal resistance will need to be lower for future higher power, lowertemperature CPUs and GPUs. Thermal resistance defined as the CPU temperature rise over theincoming water or air temperature divided by the chip power.

IT equipment chip densities has been the commonly discussed driver for adopting liquid cooling. But, there are four other reasons why data center owners should consider liquid cooling including low PUE targets, space constraints, harsh IT environment, and water restrictions. This paper describes these reasons. With this information, data center owners can make an informed decision on whether liquid cooling has advantages for…

Two-Phase, or Not Two-Phase. After all, that is the question. At least it is for data center cooling architects and planners seeking to maximize cooling efficiency and performance for their ever-growing fleets of servers with the use of liquid-cooling. The use of water-based cold plate and dielectric immersion liquid cooling solutions have seen rapid increases…

Increasing IT chip densities, a focus on energy efficiency, and new IT use cases like harsh edge computing environments are driving the interest and adoption of liquid cooling. In this paper we present the fundamentals of liquid cooling, describe the advantages over conventional air cooling, and explain the 5 main direct to chip and immersive…

Water-cooled IT equipment represents a new paradigm for datacom centre operators. As with any new approach to doing things, education will play a large role in the successful implementation of water cooling. Although most of the general rules for current air-cooled implementations apply, datacom centre operators should have cooling contingency plans; implement cooling system redundancy;…
