LG Electronics Uses LG U+ Data Center Cooling Technology

LG Electronics is launching a trial operation of a liquid cooling solution for artificial intelligence (AI) data centers (AIDC) in collaboration with LG Uplus.

LG Electronics recently announced on the 29th that it has supplied a liquid cooling solution, the Coolant Distribution Unit (CDU), to the 'Pyeongchon 2 Center', a large-scale internet data center (IDC) of LG Uplus. The company plans to test the performance of the CDU in AI server environments with high heat generation and promote the advancement of AIDC-customized liquid cooling technology.

This is the first time LG Electronics is conducting a technical demonstration of an AIDC cooling solution externally. The company plans to use this demonstration as a stepping stone to aggressively target the AIDC cooling solution market.

The liquid cooling solution attaches a cold plate to high-heat components such as the central processing unit (CPU) and graphics processing unit (GPU) and circulates coolant to directly dissipate heat. It is gaining attention as next-generation technology due to its high energy efficiency and space-saving design. Particularly, AIDCs, which use multiple CPUs and GPUs for large-scale data processing and high-performance computing, consume more power and generate more heat than traditional data centers, making liquid cooling solutions essential.

The LG Electronics CDU being demonstrated this time is based on the core component technology 'CoreTech', offering high reliability and energy efficiency. Virtual sensor technology is applied, allowing the cooling system to operate stably by correcting faulty sensor values using pump and other sensor data even if major sensors fail. Additionally, LG Electronics has applied high-efficiency inverter technology to the pump to release only the necessary amount of coolant according to the situation, enhancing energy efficiency. A highly sensitive leak sensor is also applied to strengthen the safety of the water-based cooling method. Jae-Sung Lee, Head of LG Electronics ES Business Division (Vice President), said, "We will lead the rapidly growing data center thermal management market based on our inherent technology, customer-tailored high-efficiency cooling solutions, and air conditioning business know-how."
