Let heat flow away on its own
No CDU, no chiller tower. Negative-pressure phase change carries heat out of >45KW cabinets silently, with PUE convergent below 1.08.
Industry Status
2024 – 2026
Liquid cooling isn't about better cost-effectiveness: it's about air cooling reaching its limit.
Modern AI chips have pushed past the boundaries of traditional thermal management. When a single chip needs over 1000W of cooling, air isn't an option — it's just a plan that overheats.
The mission of liquid cooling isn't saving money — it's ensuring continuous, stable operation and extended component lifespan, protecting your computing investment. That's why we chose two-phase cooling: not because it's new, but because it's the only approach that can keep pace with chip power growth.

Learning cooling
from cerebral flow.
RK-01's two-phase cooling logic follows the thermal strategy of heat-intensive organs: heat is not suppressed, but continuously carried away through dense channels, circulation, and phase change.
- 01The brain accounts for about 3-4% of body mass, yet consumes 20-25% of energy; during thinking, it can reach 30-50% of total energy consumption.
- 02The brain is one of the body's most heat-intensive organs, producing about 16% of total body heat at rest.
- 03Average brain temperature is about 38.5°C, while deep-brain temperature can reach 40.9°C.
- 04Dense cerebral vasculature and high blood flow help dissipate heat as cerebral blood flow increases.
- 05Skin is the main heat-dissipation pathway: circulation and vasodilation raise skin temperature, trigger sweating, and increase cooling.
- 06At 15°C ambient temperature, heat released from the head can account for one-third of total body heat loss.
Like the body
sweats.
The human body dissipates heat through sweat evaporation. RK-01 mimics this natural mechanism, using phase change to carry heat away in a closed-loop cycle.
- 01
Chip heats cold plate
High-power CPUs and GPUs directly heat the attached two-phase cold plate, supporting >3500W per chip and >5000W for wafer-scale cooling.
- 02
Working fluid vaporizes
Water-based working fluid vaporizes inside the cold plate, rapidly removing substantial heat through phase change — no high-power pump required.
- 03
Gas transfers outdoors
Hot gas transfers naturally through piping to the outdoor condenser, driven by temperature differential — the entire process consumes almost no energy.
- 04
Natural condensation cycle
Outdoor temperature differential condenses gas back to liquid, returning to the reservoir to complete the cycle. That's why we don't need CDUs or chiller towers.

A different dimension.
Single-phase liquid cooling is mature, but its limitations in high-power scenarios are evident. Two-phase cooling isn't an optimization — it's a solution redesigned from first principles.

PUE converges
below 1.08.
PUE measures total facility power divided by IT equipment power. 1.0 is the theoretical limit — RK-01 two-phase cooling brings PUE below 1.08.
