The explosive growth of large‑scale AI models has driven an unprecedented rise in power density within data centers. Single‑GPU chip power has exceeded 700 W, while power density per cabinet in AI clusters surpasses 15 kW. Domestic regulations also require the average PUE of data centers to drop below 1.5.
Traditional air cooling can no longer satisfy heat‑dissipation demands. Against this backdrop, liquid cooling has become a mandatory solution. Industry competition has shifted beyond cooling performance itself, focusing instead on coolant reliability, material compatibility, and consistent delivery capacity.
Three Core Challenges for Liquid‑Cooling Projects
Risks in Cooling Medium Selection
In multi‑material wetted environments, mismatched coolant easily triggers corrosion, precipitation and pipeline blockage. Complex fluid replacement and cleaning procedures may leave residual contamination, resulting in gradual performance degradation.
Thermal Pressure in System Deployment
As AI computing power keeps climbing, retrofitting existing facilities poses high implementation barriers. Challenges lie not only in heat dissipation, but also in adaptation of pipelines, power supply and daily operation & maintenance.
Difficulties in Consistent O&M & Delivery
Multi‑site cross‑regional projects demand stable supply and batch‑to‑batch consistency. Continuous monitoring of coolant conditions and fluid‑replacement cycles are required throughout operation.
Fluorinated Liquids vs. Mineral Oil: Inherent Limitations
Fluorinated liquid and mineral oil are two mainstream immersion‑cooling mediums, yet both carry obvious drawbacks：
Fluorinated liquids: Overall cost is 4‑6 times higher than synthetic oil. Fast volatility pushes up maintenance costs; volatile components raise health and environmental concerns.
Mineral oil: May cause material embrittlement, corrosion and cracking. It tends to oxidize and generate sludge and varnish, offering only 2‑3‑year service life with poor stability.
Targeting core pain points of data‑center liquid cooling and drawbacks of conventional solutions, Amer introduces the innovative C&C Solution: coordinated application of Coating (PCB protective coating) and Cooling (coolant fluid).

Metal‑Working Solutions for Liquid‑Cooling Components
Key liquid‑cooling hardware includes cold plates, water distributors, copper busbars, copper pipelines and stainless‑steel fittings, mostly made of copper, stainless steel and aluminium. Improper machining leads to oxidation, discoloration and corrosion failure, damaging sealing and heat‑transfer efficiency. Amer delivers matched metal‑working fluid solutions for liquid‑cooling parts:
01 Copper busbars & copper pipelines:
Amer SF353 copper‑specific cutting coolant. Effectively prevents copper oxidation, avoids copper soap precipitation and keeps machines clean.
02 Stainless‑steel & titanium alloy fittings & valves:
