48U Liquid-Cooled Server Rack

Liquid cooling outperforms air cooling in high-density environments running AI, machine learning and HPC workloads. PUE falls to ⁦1.05–1.15,⁩ compute density per cabinet rises by about 50%, CPU and GPU temperatures stay stable, and the equipment failure rate drops by around 20%.

Integration follows a modular approach built on three components: a coolant distribution unit (CDU) that isolates the secondary clean-fluid loop from the primary facility water loop and regulates pressure and temperature; vertical supply and return manifolds inside the rack that distribute fluid to each server chassis; and leak-proof dry-break quick-disconnects that let individual servers be hot-swapped without shutting down the loop. Many facilities run hybrid layouts, using local CDUs for high-density compute clusters while existing air cooling serves standard networking and storage racks.

The cabinet suits high-density, high-performance GPU servers built for AI training, deep learning and HPC, including 8-GPU baseboard servers and current accelerator platforms from mainstream vendors. Final compatibility is confirmed against cabinet power (36 kW or 72 kW), manifold connector type and cold-plate interface.
