Nidec has announced a bold target to grow its server liquid-cooling business to ¥100 billion by fiscal year 2031.
This isn't just an ambitious sales goal; it's a direct response to a fundamental shift in data center technology, often called a 'thermal density shock.' Modern AI chips, especially NVIDIA's next-generation platforms like the GB200 and Rubin, generate an immense amount of heat. A single high-density AI rack can produce over 120 kilowatts (kW) of heat, which is about 16 times more than a typical 7.5 kW server rack. At this level, traditional air cooling becomes impractical and inefficient, making advanced liquid cooling a necessity, not a luxury.
This technological need is backed by enormous financial investment. The world's largest cloud service providers, or 'hyperscalers' like Google and Meta, are dramatically increasing their capital expenditures (capex) to build out 'AI factories.' For 2026 alone, their combined capex is projected to be in the hundreds of billions of dollars. A significant portion of this spending is allocated not just to GPUs, but to the essential infrastructure that supports them, including power delivery and, crucially, cooling systems. This creates a vast and rapidly growing market for Nidec's solutions.
Nidec is backing its ambition with concrete action. At the recent Interop Tokyo 2026 event, the company showcased new Coolant Distribution Units (CDUs) specifically engineered for NVIDIA's latest high-density racks. More importantly, it has set a firm timeline, targeting the first quarter of 2027 for mass production. This provides a clear roadmap from product demonstration to industrial-scale delivery, adding significant credibility to its long-term revenue target.
While Nidec's focus on organic growth in this sector is clear, it's worth noting the company recently paused its M&A activities to invest in internal governance. This could be seen as a risk, potentially slowing down execution. However, it also signals a sharpened focus on delivering on its core technological promises, ensuring resources are channeled effectively into high-growth areas like liquid cooling. Nidec's move is a calculated strategy to become a key infrastructure provider for the AI revolution.
