Upgrading AI Data Center Cooling RDHx Liquid Cooling Rear Door Delivers Optimal Air to Liquid Transition
Zero Extra Floor Space, Minimal Downtime: The RDHx Rear Door as the Smart Air-to-Liquid Bridge
Our RDHx liquid cooling rear door delivers the optimal air-to-liquid transition for upgrading AI data centers. Replacing standard cabinet rear panels, it integrates dense fins and precise flow channels to absorb hot exhaust air instantly at rack outlets, eliminating recirculation, hotspots and wasted cooling. Intelligent variable-speed axial fans adjust airflow by real-time load, suiting medium-density racks and entry-level GPU clusters. RDHx works as the terminal of a full two-loop ecosystem: the primary loop cools CPU and GPU via direct-to-chip cold plates while the secondary loop captures residual storage and memory heat. EXTRCOOL provides one-stop full liquid cooling solutions.
