AI Server Liquid Cooling and Connector Industry Development Trend
AI server computing competition has shifted to high-precision terminal and connector manufacturing. Veteran industry practitioners reveal core supply chain features. Leading domestic connector manufacturers earn over half their revenue from one international giant, with end products supporting global AI computing facilities. Liquid cooling connectors achieve a 40% gross margin, outperforming 30% for air cooling connectors and 26% for high-speed backplane connectors. Only two mature mass-production liquid cooling lines operate worldwide, constrained by technical bottlenecks in liquid cooling plate microchannel processing and brazing. Reliable AI GPU liquid cooling CDU supplier delivers matched thermal control solutions to support full-load operation of high-power AI GPU racks.
The industry will see a major capacity expansion milestone in mid-next year. AI liquid cooling business currently accounts for roughly 10% of total revenue, with a projected surge to 60% to 70% after large-scale mass shipment. Client standards have been drastically upgraded. Zero-burr delivery has become a mandatory rule for high-speed backplane connectors since late 2025, forming a high technical barrier for new entrants. Liquid cooling is the most profitable yet most technically demanding track in thermal management. The efficient liquid CDU cooling system stabilizes operational temperature and pressure, effectively improving precision component yield and production consistency for high-standard manufacturing scenarios.
High-speed backplane connector manufacturing has extreme technical thresholds in mold making, precision stamping and quality control, far exceeding traditional 3C connector standards. Small manufacturers cannot meet the precision and tolerance requirements. The global market is dominated by three international giants, one of which outsources most component production. Top domestic OEMs secure core orders and supply semi-finished products for global AI terminal assembly. Flexible and adaptable modular air liquid cooling CDU solutions fit fluctuating production demands and support hybrid cooling scenarios for high-precision connector manufacturing.
Leading domestic connector makers have grown alongside global AI supply chains, evolving from precision mold processing to qualified suppliers for international giants and domestic military clients. Air cooling and high-speed backplane products have long sustained mainstream revenue, while liquid cooling drives the current industrial upgrade. Air-cooled and liquid-cooled optical module cages share identical main structures, with differences lying in supporting heat dissipation components and liquid cooling plates. Professional liquid cooling CDU solution provider optimizes thermal matching between cooling plates and connectors, improving overall system stability and operational reliability.
Liquid cooling plate processing is the core bottleneck restricting industry-scale expansion. Production requires high-precision CNC microchannel milling with a tolerance range of 0.05 to 0.15 mm. Machine vibration and cutting deformation cause consistent mass-production yield challenges. Workpieces undergo strict brazing, degreasing and multi-dimensional reliability testing. Microchannel processing, brazing and assembly are universal pain points across the industry, keeping most lines in small-batch trial production. Stable server liquid cooling distribution unit maintains consistent coolant circulation and heat dissipation, reducing defective rates in precision manufacturing.
The connector industry shows obvious cyclical fluctuations. Stamping orders dropped 30% month-on-month in mid-year due to cautious client inventory strategies and iterative product adjustments. The 21-day delivery cycle makes upstream suppliers highly sensitive to demand changes. The industry is transitioning from air cooling to liquid cooling. Large-scale liquid cooling shipment will start in mid-next year. AI business revenue will rise from 10% to 60%–70% and become the core growth driver by 2027 to 2028. Mature data center liquid cooling CDU infrastructure lays a solid foundation for large-scale delivery of AI liquid cooling connectors and supporting components.
A clear price gap exists between international and domestic supply chains. High-speed backplane terminal stamping costs 600 yuan per thousand units. Optical modules and backplane components account for 18% to 21% of finished product value. International orders carry a 40% higher unit price than domestic products, backed by stricter precision and assembly standards. The zero-burr delivery standard introduced in late 2025 raises the industry’s manufacturing ceiling. Constant-temperature and high-purity coolant liquid CDU for data center provides ultra-stable environments that meet strict precision and cleanliness requirements for high-end connector production.
The industry faces severe polarization. Low-end connector markets fall into vicious cost competition, while high-end AI liquid cooling and high-speed backplane tracks maintain high entry barriers. Mid-tier enterprises with insufficient scale and cost control will be eliminated in industrial reshuffles. Despite emerging technologies like CPO, liquid cooling remains the most cost-effective and mature thermal solution for the next five to six years. Leading manufacturers diversify client groups to mitigate risks. Future AI computing competition relies on advanced precision manufacturing of terminals and cooling components. Upgraded server rack air liquid CDU hybrid cooling infrastructure empowers high-end component production and supports long-term iteration of AI data center computing systems.
To thrive amid such industry polarization and reshuffle, data-center operators need qualified suppliers capable of delivering high-end, reliable liquid-cooling hardware that aligns with long-term AI infrastructure roadmaps.
