AI Liquid Cooling Application: RDHx Active Door Cooling
The FH92×25mm PWM fan is purpose-built for Rear-Door Heat Exchanger (RDHx) active cooling arrays in AI data centers. Deployed in 6×4 arrays on active RDHx doors, this fan delivers the high static pressure required to force hot server exhaust through dense chilled-water fin coils at rack power densities of 40–80 kW.
Why This Fan for RDHx?
- High static pressure ≥0.6 inH₂O: Overcomes fin coil resistance without airflow collapse — the most critical parameter for heat exchanger applications
- 4,500 RPM maximum speed: Delivers required CFM at high system resistance operating points
- PWM speed control (4-wire): Modulates with rack inlet temperature for energy-efficient partial-load operation
- Dual ball bearing, MTBF ≥70,000h: 24/7 operation in condensation-risk environments where chilled-water RDHx doors may see humidity above 80% RH
- Conformal coating option: Protects PCB from moisture in chilled-water proximity applications
Typical RDHx Array Configuration
42U rack door (600mm × 2,000mm): 6 columns × 4 rows = 24 units of FH92×25mm fans. Combined airflow at 0.5 inH₂O system resistance: approximately 1,400 CFM — sufficient for 60 kW rack cooling.
Compatible Systems
Active RDHx units from Schneider Electric, Vertiv, Rittal, and custom OEM rear-door configurations. Connector options: Molex 4-pin, JST, bare wire with crimped terminal. 12V, 24V, and 48V DC available.
