Chilldyne Liquid Cooling Retrofit of a Dell PowerEdge R720 / R730 Server
Five Reasons to Adopt Liquid Cooling
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…

When Sandia installed the 650-kW Attaway supercomputer at their Albuquerque HPC data center in 2019, they sought innovative cooling concepts that would reduce the massive computer system’s significant energy use. Technology partner Chilldyne offered a unique solution: a liquid system that operates under vacuum pressure for resilient, energy-efficient data center cooling. The Chilldyne cooling system…

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…

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;…
Read MoreWater-Cooled Servers Common Designs, Components, and Processes
With more water-cooled IT products arriving in the marketplace, ASHRAE TC 9.9 felt the need to outline some of the common processes, parts, and materi- als for focus in use for future water-cooled designs. Some parts in a water-cooled IT system will be specific to the product design, such as cold plates, manifolds, arrangement of…
