Elice Group said on Thursday it had secured four patents for key technologies related to AI portable modular data centres (PMDC).

The patents cover a server rack moving device and operating method for modular data centres, a fire management system and operating method for modular data centres, an air-cooled cooling system and operating method for modular data centres, and a water-cooled cooling system and operating method for server racks.

The fire management system analyses the likelihood of fire spreading based on temperature, smoke and gas sensor data. It also controls server operations by linking with an uninterruptible power supply (UPS). The cooling technology uses a water-cooling method to control heat generation in high-density environments and an air-cooling method to improve airflow efficiency in modular structures.

The technologies are now being applied to some real infrastructure and are accumulating real-time operational data. Elice Group plans to expand their use after additional verification.

Park Jeong-guk (박정국), chief technology officer at Elice Group, said the patents were the result of receiving official technical recognition for high-reliability AI infrastructure capabilities essential for running high-performance graphics processing units (GPUs). "We will present AI solution standards trusted in the global market," he said.
