Introduction
As AI data center rack power densities surge past 50kW, traditional air cooling is reaching its practical limits.
Performance Comparison
| Parameter | Air Cooling | Direct-to-Chip | Immersion |
|---|---|---|---|
| Max Rack Power | 25-40 kW | 50-100+ kW | 100-250+ kW |
| Typical PUE | 1.3-1.6 | 1.1-1.25 | 1.03-1.10 |
Conclusion
For most AI data centers, direct-to-chip liquid cooling currently represents the best balance of cooling capacity, compatibility, and cost.
