LG Electronics Accelerates AI Data Center Liquid Cooling Solutions Business

LG Electronics has commenced trial operations of liquid cooling solutions for artificial intelligence (AI) data centers in partnership with LG Uplus. The company announced on Thursday that it recently supplied Coolant Distribution Units (CDUs) to LG Uplus’ mega-scale Internet Data Center (IDC) ‘Pyeongchon 2 Center.’

The demonstration aims to test CDU performance in high-heat AI server environments and advance liquid cooling technology tailored for AI data centers. This marks LG Electronics’ first external technical validation of AI data center cooling solutions.

Liquid cooling solutions work by attaching cooling plates to high-heat components such as CPUs (Central Processing Units) and GPUs (Graphics Processing Units), then circulating coolant to directly dissipate heat. The technology is gaining attention as a next-generation solution due to its compact footprint and superior energy efficiency.

LG Electronics’ CDU leverages core technology to deliver high reliability and energy efficiency. The system incorporates virtual sensor technology that enables stable cooling system operation by utilizing pump and other sensor data even when primary sensors fail. Additionally, high-efficiency inverter technology applied to pumps optimizes energy efficiency by supplying coolant only as needed.

LG Electronics has built technological competitiveness by supplying cooling solutions to domestic and international data centers for over a decade. Recently, the company established a dedicated testbed (LG AI Data Center HVAC Solution Lab) at its Pyeongtaek chiller plant to provide optimal solutions for customers seeking to build AI data centers.

“Based on our core technology foundation, customer-tailored high-efficiency cooling solutions, and HVAC business expertise, we will lead the rapidly growing data center thermal management market,” said Lee Jae-sung, Executive Vice President and Head of LG Electronics’ ES Business Division.
