Driven by the rapid growth of artificial intelligence computing power, AI data center liquid cooling has become the mainstream cooling solution for modern high-performance computing facilities. As a core fluid distribution component in liquid cooling systems, the manifold undertakes coolant output from CDU, evenly distributes the fluid to server cold plates for heat exchange, and collects return liquid to form a complete closed circulation loop. With optimized equal-length flow channel design, it achieves ultra-low pressure drop and uniform flow distribution, laying a solid foundation for the stable and efficient operation of large-scale AI data center cooling systems.

Rising AI computing density has exhausted traditional air cooling capacity. Advanced AI data center cooling solutions have become essential to guarantee stable operation of modern high-load computing infrastructure.

The vapor compression refrigeration cycle constitutes the core operating principle of modern cold storage systems. The complete refrigeration loop relies on four essential components: compressor, condenser, throttling device and evaporator. Cooperating with circulating refrigerant, these core parts realize continuous heat exchange and stable cooling, supporting reliable cold storage operation for food, pharmaceutical and industrial preservation scenarios.

Industry practitioners once shared practical experience on PUE optimization for large scale data centers during technical exchanges in Zizhu Shanghai. The discussions covered multiple effective measures including scientific site selection reasonable humidity adjustment and replacement of traditional lighting with built in LED indicators on IT devices. Staff access control was also highlighted as human body heat emission can raise ambient temperature significantly. These free technical sessions attracted limited audiences while many successful business leaders tend to study traditional philosophy and religious classics for social identity and spiritual comfort. Such experience and insights are valuable references for the operation and optimization of liquid cooling for AI GPU data center.

CoolIT Systems was founded in 2001 and initially developed and distributed premium direct liquid cooling products for desktop gaming devices. As market demand grew, the company expanded its business to serve data center and server OEMs starting from 2014. Headquartered in Calgary Canada the firm operates three manufacturing warehouses across Canada and China with a global sales network. Partnered with Wuxi Fuman Technology in China CoolIT has established itself as a trusted data center liquid cooling supplier specializing in cold plates CDU units and racks for diverse industrial scenarios

Following our previous discussion on the rise of liquid cooling technology, this article elaborates on the principles, pros and cons of mainstream liquid cooling approaches. It provides practical selection guidance for enterprises to adopt the optimal data center liquid cooling solution tailored to diverse operational scenarios.

The global liquid cooling component market is long dominated by Taiwanese European and American enterprises. Taiwanese firms hold over seventy percent of the cold plate market and sixty percent of quick coupling segments. Vertiv leads the global CDU market while Taiwanese brands dominate mainstream data center cooling manifold supplies. Global high end data center supply chains were once monopolized by foreign vendors. Currently global cloud giants including Google Meta and Amazon are diversifying supply chains. Empowered by technological progress and cost advantages Chinese liquid cooling manufacturers have gained crucial global market access.

Google launches large scale TPU cluster deployment in June 2026 with annual TPU shipments raised fifty percent to six million units. TPU v7 chips with 980W high power consumption fully adopt liquid cooling driving surging demand for premium AI data center cooling equipment. Traditional Taiwanese and Japanese liquid cooling suppliers fail to meet Google’s rapid capacity expansion due to insufficient output and slow delivery. Widening overseas supply gaps create huge opportunities for Chinese vendors. With advanced capacity layout mature technologies and cost advantages domestic players capture spillover orders and enter a steady performance growth phase for professional data center liquid cooling solution deployment.

Booming AI large models supercomputing and high-density computing clusters are driving comprehensive upgrades in data center thermal management. As single rack power surges from 5-8kW to 20kW, 40kW and even 60kW, traditional air cooling has reached physical limits. Issues including insufficient heat dissipation, server throttling, high PUE and accelerated hardware aging have made liquid cooling data center solutions essential for modern high-performance computing, accelerating the upgrade of water cooled data center infrastructure across the industry.

Driven by booming AI computing demand, data center CDU systems are undergoing comprehensive technical iteration. Upgraded CDU solutions support high-density AI computing scenarios, enabling large-scale deployment and efficient transformation for new and legacy data center liquid cooling renovation projects.
