Liquid Cooling Manifold Indispensable Core Component for Server Heat Dissipation
Liquid cooling manifold functions as key flow distribution piping device inside server racks. Situated between cold plate CDU and cold plates, it evenly distributes coolant to server modules and dissipates heat from high-density electronic components, maintaining stable device performance. Sophisticated internal channel design ensures smooth and balanced liquid circulation, laying solid foundation for reliable data center liquid cooling system operation.
In standard 42U rack deployment, one manifold links 16 to 24 cold plate ports. Strict flow deviation control within 5% avoids sharp temperature surge of single nodes, satisfying rigorous operating requirements of AI data center cooling.
Made primarily of 304 stainless steel and higher-grade materials, most manifolds resist coolant corrosion and boast over 10 years service life. Laser welding and vacuum brazing deliver superior sealing effect. Diversified outer sizes well adapt to layout demands of conventional data center liquid cooling pipe.
Products are divided into single-row and double-row structures to match racks of different power levels. Equal-length channel design effectively balances fluid delivery. Compatible with mainstream quick connectors, the component supports pressure-bearing hot swapping with tiny leakage volume, securing smooth circulation of qualified server cooling liquid.
Adopting cold and heat separated dual-channel structure, the manifold equipped on ASUS AI POD realizes convenient blind insertion connection. It greatly simplifies equipment assembly and improves practical application efficiency of customized AI data center liquid cooling pipe.
CDU controls total cooling supply while manifold regulates even cooling distribution. Matching flow capacity and pressure resistance can eliminate insufficient cooling transmission, enabling coordinated and efficient system operation.
CDU and manifold take up 30% to 35% of total liquid cooling system cost. Driven by growing computing density, integrated modular design cuts leakage risks substantially. Built-in sensors achieve dynamic cooling adjustment and elevate operating efficiency of energy saving liquid cooling system. The industry also keeps exploring practical methods concerning how much energy does liquid cooling save to lower long-term operating expenditure.
Regarded as brain and terminal delivery unit of liquid cooling loop respectively, CDU and manifold jointly guarantee non-degradation running of high-power AI servers. With liquid cooling penetration rate expected to hit 30% in 2028, the two core parts will develop toward customized solutions and keep advancing alongside soaring AI computing demands.
