Graphene coolant（AI server）
1. What is graphene coolant?
-
Composition principle： Disperses nanoscale graphene or modified graphene flakes into the base liquid (such as deionized water, ethylene glycol, or specialized coolants) using surface modification techniques to form a uniform and long-term stable "nanofluid (Nanofluid)".
-
Operating mechanism： Utilizes graphene's exceptionally high thermal conductivity to significantly enhance the coolant's overall thermal conductivity and convective heat transfer efficiency.
2. Key advantages in AI servers
-
Significantly increased heat conduction efficiency： Compared to traditional water/ethylene glycol mixtures, adding modified graphene can increase the liquid's thermal conductivity by 15%～30% or more, enabling faster extraction of high heat from the chip core (Die).
-
Reduce thermal resistance and chip junction temperature (Junction Temp)： Effectively suppresses instantaneous temperature spikes of chips during full-load computation, ensuring the stability and computational performance of AI model training and inference.
-
Corrosion resistance and anti-sedimentation： High-quality graphene coolants have good dispersion stability and chemical resistance, preventing blockages in microchannel cooling plates (Microchannel) or corrosion of metal piping.
-
Energy savings and reduced consumption (lowering PUE)： With improved heat dissipation efficiency, pump load and circulation flow requirements can be reduced, further decreasing the overall cooling power consumption of data centers.
