Air-liquid mixed cooling cabinet | 48U

48U Liquid-Cooled Server Rack | Air-to-Liquid Cooling Solution

The Lianli 48U liquid cooled server rack completely breaks through the power density limit of traditional air cooling through its revolutionary dual-mode cooling architecture: its intelligently switched liquid cooling module (supports single-phase immersion/cold plate) efficiently dissipates heat, while the redundant EC fan wall ensures 35kW-level uniform air cooling coverage, achieving a total cooling capacity of 55kW for a single cabinet; reducing PUE to below 1.15, reducing cooling electricity costs by 50%. At the same time, the military-grade reliable design (IP42 protection) and zero-modification compatibility allow customers to reduce TCO by 45% and safely carry critical loads such as AI training clusters and GPU supercomputing.

Product Specifications

Why Professionals Choose the 48U Liquid-Cooled Server Rack
1. High-Density Thermal Management
As CPU and GPU TDPs exceed 400W–700W, traditional air cooling faces "thermal runaway." Our Air-to-Liquid design utilizes high-performance heat exchangers to capture heat at the source, ensuring components remain within optimal T-junction temperatures even under 100% load.

2. Seamless Facility Integration
Unlike "Liquid-to-Liquid" systems that require dedicated secondary water loops, the Air-to-Liquid configuration can exhaust heat back into the hot aisle or integrate with existing CHW (Chilled Water) lines. This makes it the ideal choice for brownfield data center upgrades.

3. Redundancy & Reliability

• Leak-Free Technology: Equipped with industrial-grade, non-drip quick-connect couplings.
• N+1 Power & Cooling: Dual power feeds and redundant pump configurations within the CDU (Cooling Distribution Unit).
• Real-Time Telemetry: Full integration with DCIM (Data Center Infrastructure Management) via SNMP or Modbus.

Optimized for Modern Hardware
Specifically designed to house and cool power-hungry server architectures, including:

• NVIDIA HGX™ / DGX™ H100/H200, B100/B200, GB200/GB300 platforms.
• Intel® Xeon® Scalable and AMD EPYC™ high-core-count nodes.
• Multi-node storage arrays and high-speed networking switches.
