What is Liquid Immersion Cooling ?
energy consumption at the same time that the industry was starting to make real and meaningful investment into sustainability .”
Capes joined Bitfury in 2019 , and has since overseen LiquidStack ’ s spin-out into its own company , a move which “ ultimately pivoted us out of the crypto industry and into data centres , high performance computing , and the edge .”
From the Hyperscale to the Edge : Hermetically Sealed and Hyper-Dense Liquid cooling isn ’ t just garnering attention among hyperscalers and HPC operators .
Liquid immersion cooling is easily one of the most modern and potentially exciting forms of modern data centre cooling . Liquid , including water , is a far more efficient way to transfer heat than cold air - the traditional medium for cooling a data centre . Water cooled data centre racks have fantastic power efficiency , but the threat of damage from any water at all coming into direct contact with several hundred thousand dollars worth of computing equipment has prevented the technology from seeing much adoption . Liquid immersion cooling uses a dielectric coolant fluid rather than water to gather the heat from server components . Dielectric fluid , unlike water , can come into direct contact with electrical components ( like CPU ’ s , drives , memory , etc .) without causing damage and , in the case of companies like LiquidStack , transfers heat even more efficiently than water . The company ’ s liquid cooling solutions ( in a business context and also in the sense of the literal solutions it pumps across a piping hot server ) claim to be able to provide a 4000 times higher heat transfer coefficient compared to air , 21 times more heat rejection per IT rack compared to air cooling , a 41 % decrease in energy consumption compared to air cooling , and ( this is the big selling point ) a 26 % higher capacity for cooling than any other form of liquid cooling on the market today . datacentremagazine . com 85
