Two Types of CDU Feature Comparison & Product Specifications
Liquid-liquid CDU needs primary coolant supply to function properly. Air-liquid CDU eliminates such requirement. Secondary coolant absorbs heat when flowing through servers, then dissipates heat to surrounding air via air-cooled heat exchangers. Its simpler structure marks obvious technical differences in liquid cooling vs air cooling data center solutions.
Relevant design criteria are stated in the technical specification for server and storage liquid cooling devices. American brand BOYD has rolled out a 10U air-liquid CDU model. The compact unit offers practical deployment choices and well fits the application demands of rack level liquid cooling.
The product features standard dimensional parameters of 534mm×440mm×849mm with a net weight of 95kg. It reaches maximum cooling capacity of 32kW under rated operating conditions. Adopting multiple common cooling medium, the equipment delivers steady heat exchange performance suitable for row level liquid cooling scenarios.
It supports 45°C maximum inlet air temperature and 1.5-inch sanitary clamp interface. Restricted by safe working pressure, power consumption and ambient limits, the unit can work reliably under complex outdoor and indoor environments, fully meeting the layout requirements of container data center liquid cooling.

Power modules, fans and pumps adopt N+1 redundant design. The system realizes real-time monitoring on flow rate, temperature and component lifespan, equipped with automatic refilling and leakage detection functions. Reliable structural design reduces unnecessary energy loss and effectively optimizes data center liquid cooling PUE.
With stable heat dissipation capacity and flexible pipeline matching, the air-liquid CDU can efficiently take away massive heat generated by powerful computing hardware. It provides dependable thermal protection tailored for GPU server liquid cooling operation.
The product runs stably within wide voltage and humidity range, with outstanding insulation performance and anti-failure capability. It copes well with intense heat load and satisfies core operating needs of high density server cooling.
Dual cooling structure and intelligent monitoring system greatly enhance overall operational efficiency. Mature air-liquid CDU technology lays solid foundation for stable, continuous and efficient liquid cooling high density computing in modern data centers.
