Nidec is developing and rolling out in-house a product lineup that plays a central role in the liquid-cooling market for AI data centers. After acquiring Taiwan-based CCI in 2018 and integrating its technology, the company has brought CDUs, cold plates and QDs in-house, built a product lineup supporting systems up to the 2MW class, and advanced compatibility with OCP and Deschutes.
Nidec has developed in-house a range of core liquid-cooling components for AI data centers, centered on CDUs and including In-Rack CDUs, In-Row CDUs, cold plates, manifolds, pumps and QDs. In line with the Open Compute Project's technical framework, it has established a platform compliant with DTC liquid-cooling standards.
The company's liquid-cooling business began with its acquisition of Taiwan-based CCI in 2018. It has leveraged the precision machining, airtightness testing and mass-production capabilities developed in its motor business to extend thermal technologies such as heat sinks, heat pipes and vapor chambers into liquid cooling.
The company has already achieved the world's first mass production of a 250kW CDU in a 4U form factor, while its 2MW-class In-Row CDU is compatible with Google's Project Deschutes. In 2026, it announced a prototype In-Rack CDU with a maximum capacity of 300kW and plans to begin mass production in 2027.
In Japan, Nidec has launched an alliance with 第一実業 and カンネツ to provide an integrated offering covering the design, procurement, construction and testing of liquid-cooled data centers, promoting implementation across the liquid-cooling system. It is also building an operating structure linked to its overseas facilities, including the use of its Thailand facility as a core mass-production base.
