Nidec Journal Inside provides a look inside Nidec’s various businesses to unveil technologies to dive Nidec forward and employees’ feelings.
In this commemorative edition, we feature the datacenter water-cooling business that supports AI’s evolution.
As sophisticated AI servers become common rapidly in recent years, the extreme heat from those servers exists as a big issue. As the conventional, fan-using air-cooling method reaches its limit in addressing the issue, the water-cooling method, which uses water and other liquids to cool devices effectively, is gaining a lot of attention lately.
By providing a behind-the-scenes look in this new area of business, this edition of Nidec Journal Inside reveals how Nidec takes on issues.

Entry into the water-cooling business

The water-cooling business is a completely new business for Nidec. While, at a glance, it may look different from our existing businesses, it actually turned out to be a field where we can utilize the precision machining and control technologies that Nidec has long fostered in its hard disk drive (HDD) development. Here’s how we started taking on challenges in this area, where we can utilize our strengths exactly as they are.

Meeting customers’ expectations

To meet our customers’ expectations – “Nidec should be able to do this.” – our development team had to start from scratch. Not knowing anything about this business, we researched all issues to solve them one by one. See how our engineers did their job in the initial stage of product development.

Absolute water-leak prevention

To datacenters, home to precision machines, the biggest worry was water leak. By applying the “absolute anti-leakage” design nurtured in its HDD development, Nidec successfully proved its products’ overwhelming safety. This section depicts our tenacity to meet customers’ expectations and a moment we achieved a major goal – which was great enough for us to do high fives with our customer at the workplace.

Nurturing the water-cooling business

To Nidec, selling water-cooling products isn’t the end of business, as customers will continue to use these products for 10, or even 15 years. This is why we entered a new business phase of building a maintenance and service system in addition to developing and selling products. By transforming our partner companies’ deep trust and the joy of seeing our products launched in the market into power, the frontline of this business and the rest of our team will grow further, as you will see in this segment.

Never stop taking on challenges

As AI society evolves rapidly, anti-heat measures for servers remain a central issue of society. In this section, you will see Nidec go beyond the phase of simply making what we are told to do to enter a new phase of utilizing our own technology to create global standards. Check how Nidec’s engineers continuously take on challenges for the future by aiming to become a leading company in the water-cooling industry.
