Patent 07:
Sub-Ambient Control
Active Vapor-Compression Architecture
Pushing premium hardware past the physical limitations of facility water. A localized Refrigeration Delivery Unit (RDU) providing highly controlled -15°C to 0°C dielectric flow, protected by an absolute dew-point purge lock.
Core Technology Modules
Combining rugged refrigeration cycles with precision environmental physics to safely drop hardware below the facility condensation line.
Active Rack-Level Refrigeration
A sophisticated vapor-compression sub-system engineered directly into the rack envelope. Bypassing standard facility water lines to deliver a clean, particle-free dielectric secondary loop actively chilled below 0°C.
Dew-Point Safety Lock
Sub-ambient fluids historically destroy hardware via condensation. DC-P07 integrates a micro-climate sensory array and dry-air gas purge system inside the compute tray, forcefully keeping the local environment safely below critical dew-point thresholds.
Telemetry-Driven Exergy
Blind refrigeration wastes power. The compressor is governed by adaptive control logic that actively reads semiconductor junction telemetry, allocating chilling effort strictly where needed to prevent electrical leakage and throttling.

Validating the system loop and hardware boundaries of the Sub-Ambient Refrigeration Platform.
View A: Rack Fluid Hierarchy
Volumetric mapping of the in-rack components, defining the boundary between the active refrigeration compressor and the standard facility water loop interface.
View B: Tray Dew-Point Control
Exploded view of the compute tray showcasing the physical gas-purge manifolds responsible for defending the silicon from atmospheric condensation.
View C: Sub-Ambient P&ID
Process integration diagram logging the telemetry loops between the cooling compressor hardware and the semiconductor junction variables.
Commercial Revenue & Hardware Moat
Diamond.Cool actively positions this IP as heavily differentiated from mainstream data center chillers. This is an elite hardware tier for workloads that standard water cooling cannot satisfy.
The Mainstream Boundary
Mainstream AI racks are adopting direct liquid (water/glycol) to survive. But water loops bottom out near 20°C. For bleeding-edge sectors, 20°C junction performance still leaves massive silicon clock potential locked away behind thermal throttling walls.
The Investment Thesis
Operators of highly optimized AI clusters will pay massive premiums for a contained module that safely drives silicon temperatures down to -10°C, unlocking a sustained 8% to 15% clock speed boost on otherwise saturated hardware.
Diamond.Cool Revenue Model (Sub-Ambient IP Licensing)
Because active refrigeration CDUs already exist on the market, Diamond.Cool's defensive revenue play sits entirely on the Dew-Point Safety Control and Telemetry Logic. By licensing this exact protective control scheme to Tier-1 system vendors, Diamond.Cool guarantees a massive, risk-free cut of the premium hardware market without needing to manufacture the massive compressors directly. Furthermore, we explicitly isolate our licensing from incoming global "PFAS chemical" bans, utilizing purely compliant low-temp dielectric pathways.
