SEOUL, December 11 (AJP) - KT Cloud has launched South Korea’s first commercial liquid-cooling system using direct-to-chip (D2C) technology, stepping up efforts to capture a growing share of the AI data center market.
The company on Thursday opened a center which replicates a full AI data center environment to showcase high-efficiency, high-reliability operations.
D2C cooling works by attaching a cold plate directly to a server’s GPU chip and circulating coolant to remove heat. KT Cloud said the method delivers significantly better heat management than traditional air-cooling systems, cutting power consumption by 20 to 30 percent.
The company has built server and rack load systems that meet global AI server specifications, testing variables such as coolant flow, pressure and temperature. The technology is already in commercial operation at KT Cloud’s Gasan AI data center, with upcoming facilities in Bucheon, Gaebong and Ansan designed to support liquid-cooling.
KT Cloud also demonstrated an immersion-cooling setup — submerging servers in a dielectric liquid — which achieved up to 60 percent power savings during load tests.
With AI infrastructure demand accelerating, KT Cloud said it will concentrate on developing next-generation cooling technologies.
“There is growing demand for liquid-cooling technology among industries requiring high-performance computing and among cloud providers,” said Heo Young-man, head of the company’s data center division. “Although domestic experience is still limited, we aim to emerge as a leading AI data center player when services begin in April.”
