LG Electronics has announced its collaboration with LG Uplus to pilot an advanced liquid cooling solution for AI Data Centers (AIDC). The company is currently supplying a Coolant Distribution Unit (CDU) to LG Uplus’s large-scale Internet Data Center (IDC), Pyeongchon 2 Center, in order to verify the performance of the CDU design in high-heat AI server environments.
This testing marks LG Electronics’ first external validation of its specialized liquid cooling technology aimed at AI data centers. Based on the results, LG plans to accelerate its market efforts to expand its presence in this rapidly growing sector.
The liquid cooling solution involves attaching cooling plates to high-heat components such as CPUs and GPUs, circulating cooling water directly to efficiently dissipate heat. This method is gaining attention as a next-generation data center cooling technology because of its space-saving benefits and superior energy efficiency.
AI data centers utilize numerous high-performance processors, resulting in significantly higher power consumption and heat generation compared to traditional data centers. Therefore, implementing effective liquid cooling technology is considered essential.
LG Electronics’ CDU, developed with the company’s proprietary "Core Tech" platform, has been optimized for safety and energy efficiency. It features virtual sensors that maintain stable operation even if sensor failure occurs, by utilizing data from pumps and other sensors. Its high-efficiency inverter pump adjusts water flow according to demand, maximizing energy savings. Additionally, sensitive leak detection sensors enhance safety.
With more than a decade of experience in data center cooling solutions, LG Electronics has shifted from traditional water-cooled chillers toward air-cooled chillers and liquid cooling solutions tailored to the needs of AI data centers, actively responding to market changes.
At the recent Data Center World 2025 conference in Washington D.C., LG showcased its CDU products, solidifying its position in the global market.
LG also offers hybrid cooling solutions, which apply cost-effective air cooling in low-heat zones and liquid cooling in high-heat zones with dense component arrangements. This approach ensures optimal cooling performance while reducing energy consumption.
Recently, LG has established a dedicated test bed within its Pyeongtaek chiller plant to simulate diverse AI server environments for systematic validation and improvement of its cooling solutions.
Lee Jae-sung, Vice President and head of LG’s ES Business Division, stated, “Leveraging our core technology, customized high-efficiency cooling solutions, and extensive HVAC expertise, we will lead the rapidly expanding data center thermal management market.”
