AI Liquid Cooling Revolution: Industry Breakthrough, Technical Iteration and Massive Market Opportunities
With the power consumption of NVIDIA GB300 chips exceeding 1400W per card, traditional air cooling systems have encountered fatal bottlenecks and survival crises. Air cooling, with a maximum rack heat dissipation capacity of merely 20kW, fails to support 100kW+ AI server clusters, resulting in a 50% drop in equipment reliability and service life, as well as frequent system crashes and downtime. Advanced liquid cooling distribution unit delivers precise and balanced coolant circulation, solving uneven heat dissipation issues caused by ultra-high chip power density and stabilizing the overall operation of high-load AI computing facilities.
A fierce race between computing power and heat dissipation is sweeping the industry, with AI chip thermal density climbing 30% annually. NVIDIA’s next-generation Rubin chip is expected to exceed 1800W in power consumption, pushing single rack power density to 132kW. Server reliability decreases by 50% for every 10°C temperature rise, while air-cooled GPU core temperatures often exceed 95°C, far beyond the 80°C safety threshold. Professional AI data center thermal management systems adopt scientific temperature control strategies, effectively suppressing extreme temperature spikes and ensuring long-term stable operation of high-end AI GPU clusters.
Liquid cooling has become the core breakthrough solution for data center heat dissipation upgrades. Liquid medium boasts 1000 times higher thermal conductivity and over 3000 times higher specific heat capacity than air, stably controlling chip core temperatures below 65°C. Real industry cases prove that immersion liquid cooling helps Alibaba Hangzhou Data Center achieve a PUE as low as 1.09 with 70% energy savings, while Tencent Tianjin Data Center reduces annual power consumption by 24 million kWh via cold plate liquid cooling. High-performance high efficiency CDU for data center further optimizes energy utilization, enabling data center PUE to drop below 1.05 and completely outperforming traditional air cooling systems with a PUE above 1.4.
Liquid cooling technology generates remarkable economic and policy value. It cuts data center investment costs by 10%-14% compared with air cooling, fully supporting stable operation of super-scale GPU clusters such as Tesla xAI Colossus with 100,000 H100 GPUs. In line with national policies requiring new data center PUE ≤ 1.25, liquid cooling has evolved from an optional upgrade to a mandatory standard. Optimized rack cooling solutions adapt to ultra-high power density racks ranging from 40kW to 750kW, perfectly matching the iterative upgrade needs of modern AI intelligent computing centers.
The global liquid cooling market is witnessing explosive growth. China’s intelligent computing center liquid cooling market scale reached RMB 18.4 billion in 2024 and is projected to soar to RMB 130 billion by 2029 with a CAGR exceeding 45%. The global liquid cooling server market will expand from USD 5.87 billion in 2023 to USD 32–35 billion in 2030, with China’s penetration rate jumping from 12% to over 45%. A complete and reliable data centre liquid cooling system covers cold plate and immersion dual technical routes, supporting large-scale commercial deployment and rapid market penetration across diverse computing scenarios.
The domestic liquid cooling industry forms a dual-track development pattern dominated by cold plate cooling and supplemented by fast-growing immersion cooling. Cold plate liquid cooling occupies 80%-90% of the current market share, featuring strong compatibility, low renovation costs and mature technology, ideal for legacy data center upgrades and medium-to-high density computing scenarios. Professional cold plate CDU realizes efficient heat exchange by cooperating with metal cold plates, adapting to 10–250kW racks and fully matching mainstream computing devices such as NVIDIA B-series GPUs, with low leakage risks and outstanding operational safety.
As the ultimate solution for ultra-high-density computing, immersion liquid cooling supports single rack power density above 750kW, achieving an ultra-low PUE of 1.03–1.05 and over 95% heat dissipation efficiency. It has been widely applied in supercomputing centers and large-scale AI training clusters, with market growth rate exceeding 35%. Leading enterprises including Sugon and Inspur have verified its commercial value, accelerating industrial maturity. Mature AI data center liquid cooling solutions cover single-phase and two-phase immersion technologies, meeting the extreme heat dissipation demands of high-end AI training and inference clusters.
Driven by dual catalysts of policy regulation and AI computing demand explosion, the liquid cooling industry has entered a large-scale growth stage from pilot verification. Leading manufacturers continue to iterate core technologies, reduce renovation costs and improve system reliability, while upstream and downstream industrial chains achieve rapid domestic substitution. The flexible custom air liquid cooling CDU supports personalized parameter adjustment and structural customization, adapting to differentiated construction, renovation and ultra-high power density scenarios of various AI data centers, and empowering the high-quality development of global intelligent computing infrastructure.
