specifically designed for high-load AI GPU such as the NVIDIA GB200/GB300

While liquid cooling technology offers stable operation, its slow heat dissipation under extremely high loads can easily lead to performance bottlenecks.


Nitrogen cooling, although providing extremely rapid cooling, consumes a huge amount of energy, resulting in excessively high operating costs and hindering large-scale commercial application. This invention resolves the conflict between "high-performance operation" and "cooling costs" for servers, preventing servers from throttling or becoming damaged due to overheating.


The module dynamically switches cooling modes based on server load, maintaining the server stably at 45°C. Its heat dissipation speed is 2.5 times faster than traditional single liquid cooling systems, achieving a cooling efficiency of 5°C per second.

This invention solves a major flaw in existing technologies that cannot balance heat dissipation speed and cost-effectiveness. Traditional systems often have to choose between "insufficient heat dissipation (single liquid cooling)" or "excessive cost (single nitrogen cooling)".
