Dell develops leak detection technology for liquid cooling systems


Dell has developed Liquid Cooling System (LCC) leak detection technology for server stations. The resource writes about it DigiTimesciting Eric Leung, director of enterprise solutions for Dell EMC. In addition to server solutions, Dell also manufactures consumer computers that use LSS. It is very likely that the developed technology may sooner or later migrate to the products of the company and this segment.

Since traditional air-cooled systems only achieve a PUE of 1.4, server owners wanting to keep the PUE below 1.2 need to use LSS. To date, the share of such solutions in the server market is still less than 1% of the total number of used cooling systems. However, the demand for such solutions grows as the performance and power consumption of CPUs and GPUs increase, which encourages manufacturers to use more efficient cooling methods. At the same time, manufacturers are striving to improve their LSS, due to which technologies such as those created by Dell are born.

DigiTimes notes that the upcoming 10nm Intel Ice Lake-SP server processors will be able to process data 1.5-8 times faster than their predecessors, but at the same time their power consumption will also increase – from 150-200 to 250-300 watts. AMD Milan EPYC 7763 processors in systems with Instinct MI100 computing accelerators can consume up to 280 watts of power, which is also quite a lot.

The resource indicates that the server segment of Alibaba has already implemented immersion-type liquid cooling. Microsoft, Google and Facebook are also considering switching to liquid cooling systems for their data centers. For example, the Open Compute Project conglomerate, led by Facebook, is soon certifying new standards for the use of reinforcing backplates with integrated LSS. Microsoft and Google, in turn, plan to resort to two-phase immersion cooling.
