Panasonic is expanding its long-standing pump technology into the growing field of AI data center cooling. As advanced chips generate higher heat levels, liquid cooling has become an important solution due to its efficiency compared to air-based systems. Building on 70 years of pump development, Panasonic has created compact liquid cooling pumps designed for Coolant Distribution Units (CDUs), which circulate coolant to manage heat inside AI servers.
The company’s In-Rack CDU fits three pumps into a 4U server space, enabling continuous operation with a built-in backup pump. Panasonic developed new pump components to increase coolant flow without increasing size. Through magnetic field, fluid, and flow analysis, engineers raised the flow rate from 40 to 70 liters per minute. The design also uses encapsulation and self-lubricating bearings to reduce heat, improve efficiency, and extend operating life.
Close collaboration with Panasonic’s local sales company in Taiwan has supported business growth in a major data center hub. Manufacturing and development take place at the Hikone Plant in Japan, where integrated production and cross-functional teams help adapt to evolving customer needs. With plans to expand the plant by 2028 and a goal of 100 million cumulative pump shipments by 2035, Panasonic aims to support the continued development of AI-related infrastructure and a more sustainable digital environment.
