To address the enormous amount of heat generated by AI servers, DJK is strengthening an engineering structure that goes beyond the conventional role of a trading company. DJK has integrated the liquid-cooling piping design and Thermal management technologies of KANNETSU THERMAL ENG. CO., LTD. (hereinafter “Kannetsu”) with high-performance coolant distribution units (CDUs) manufactured by NIDEC CORPORATION (hereinafter “Nidec”). This integrated solution is designed to both reduce power consumption at DCs and efficiently cool high-density servers.
DJK also proposes a hybrid cooling system that combines these advanced liquid-cooling technologies with waste heat recovery technology, enabling effective use of heat generated during power generation. Through the introduction of this system, DJK aims to achieve a power usage effectiveness (PUE) of below 1.1, a world-class performance target, while meeting the needs of DC operators seeking to reduce both environmental impact and operating costs.
