LG Electronics is accelerating the expansion of its AI Data Center (AIDC) liquid cooling solution business.

LG Electronics recently began a verification test by supplying a liquid cooling solution, the Coolant Distribution Unit (CDU), to LG U+'s large-scale Internet Data Center (IDC), Pyeongchon 2 Center.

This is the first case of LG Electronics conducting a technology demonstration in an external AI data center, and based on this demonstration, it plans to advance liquid cooling technology and expand the market.

Liquid cooling solutions are methods of directly cooling the heat generated by attaching a cold plate to the CPU (Central Processing Unit) and GPU (Graphics Processing Unit), which are high-heat components, and flowing coolant. They are characterized by superior space utilization and high energy efficiency compared to conventional air cooling methods.

In particular, AI data centers perform large-scale calculations, and as high power consumption and increased heat generation are inevitable, more efficient cooling technology is required than in existing data centers. Accordingly, liquid cooling solutions are becoming an essential technology for next-generation data centers.

The LG Electronics CDU that is conducting this demonstration is based on ‘CoreTech’ and has high reliability and energy efficiency. By applying virtual sensor technology, the system can be operated stably by utilizing pump and other sensor data even if the main sensor fails.

In addition, energy saving effects were maximized by applying high-efficiency inverter technology to the pump to supply the required amount of cooling water depending on the situation. Safety was also enhanced by applying a highly sensitive water leak sensor to enhance the safety of the water-based cooling method.

LG Electronics has been supplying cooling solutions to domestic and international data centers for over 10 years and has built up competitiveness in the air conditioning system sector. Starting with the existing water-cooled chiller-centered business, it is developing air-cooled free-cooling chillers and liquid cooling solutions in line with the changing trends of the AI data center market, and is moving to take the lead in the market.

In particular, LG Electronics also has a hybrid cooling solution for AI data centers to respond to various customer needs. It provides an optimized cooling solution by applying air cooling to servers with low heat generation and liquid cooling to servers with high heat generation.

LG Electronics has built a test bed dedicated to AI data centers (LG AI Data Center HVAC Solution Lab) at its Pyeongtaek chiller plant and is verifying the effectiveness of cooling technology by reproducing various AI server environments.

LG Electronics ES Business Division Head Vice President Lee Jae-sung said, “We will lead the rapidly growing data center thermal management market based on our inherent technological prowess based on CoreTech, customized high-efficiency cooling solutions, and know-how in the air conditioning business.”
