Background of Technical Cooperation
Client: Transformation of an AI computing power service provider | Equipment: 1,000 Dong'ao Xiong water-cooled B2 (140TH/s)
Technical Requirement: Solve the heat dissipation bottleneck of high-density mining machines and achieve overclocking efficiency.
Liquid Cooling Technical SolutionCooling System:
Single-phase immersion liquid cooling (Coolant: Engineered Fluid EF-100)
- Cabinet power density: 100kW/cabinet (traditional air cooling limit is 35kW)
- PUE value: 1.03 (compared with 1.25 for air cooling)
Energy Recycling:
- Waste heat recovery: Supply greenhouse planting in the park (annual heating cost savings of $280K)
- Grid frequency regulation: Respond to regional power grid load instructions and obtain $0.012/kWh compensation
Computing Power Optimization:
- Chip constant temperature at 45℃: Overclocked to 245TH/s (6.5% higher than the nominal value)
- Failure rate:<0.8%>
