How It Works
From GPU to Dissipator
Heat Pickup at GPU
The AL-NH₃ heat pipe evaporator contacts the GPU heat spreader, absorbing heat through phase-change evaporation at near-constant temperature.
Transport Along Heat Pipe
Vaporized NH₃ travels along the sealed heat pipe at near-zero pressure drop, carrying heat to the external dissipator outside the rack.
Condensation & Dissipation
At the condenser end outside the rack, heat is released via air fins or a liquid-cooled heat exchanger. No electronics, no pump.
Modular Stacking
Each module handles one GPU node at 600 W. Add modules as GPU density grows — no rack redesign, no new coolant infrastructure.
Scalable Capacity
Stack modules to match your rack TDP — no new infrastructure required.
Air or liquid-cooled external dissipation options available.
Performance Data
System test data being compiled
Thermal resistance, heat rejection capacity per module, and GPU junction temperature data under sustained load. Live demonstrations running at COMPUTEX 2026.
