Introduction
As high-performance computing, AI infrastructure, electric vehicles, and power electronics continue to scale, traditional air cooling is no longer sufficient to manage increasing thermal loads. Liquid cooling-particularly liquid cold plate technology-has emerged as a critical solution due to its significantly higher heat transfer efficiency compared to air-based systems. Industry data indicates that liquid cooling can deliver 4–5 times higher thermal efficiency, making it essential for high-density applications such as data centers and power modules .
China has rapidly become a central hub for liquid cold plate manufacturing, supported by strong capabilities in CNC machining, brazing, friction stir welding (FSW), and micro-channel processing. Recent developments also highlight growing global demand, with international tech companies actively sourcing liquid cooling systems from Chinese suppliers to support AI-driven infrastructure expansion .
