Data Center Liquid Cooling Era
Green Cooling Partner
With the ever increasing demand for computing density driven by AI, HPC and edge computing, liquid cooling has become the mainstream choice for data center thermal management. Whether you adopt cold plate liquid cooling, single-phase immersion cooling or two-phase immersion cooling, the final “heat outlet” always relies on an efficient, stable and energysaving outdoor cooling source. NEWIN closed circuit cooling towers and adiabatic coolers are precisely the system level cooling source that matches all liquid cooling architectures - 100% natural cooling, compressor-free, PUE ≤ 1.1.
Cold Plate Liquid Cooling + Closed Circuit Cooling Tower
Cold Plate Liquid Cooling Solution
Application scenarios: AI inference, general data centers, retrofit of existing air cooled server rooms
Cold plate liquid cooling only cools the hottest chips (CPU/GPU) locally, while other components can still rely on air cooling.
This solution offers high compatibility with existing air cooled infrastructure and low retrofit cost.
Cold Plate Liquid Cooling Solution | Working Principle
The closed circuit cooling tower provides a 5°C ΔT on the primary side (e.g. supply 30°C / return 35°C), while the secondary side liquid of the cold plate achieves a 10°C ΔT (e.g. 44°C → 34°C), efficiently removing heat from the chip.
► Recommended cooling source: NWF Series Closed Circuit Cooling Tower
♦ Compressor-free, year-round natural cooling, PUE ≤ 1.2, 25%–35% reduction in total annual energy consumption
♦ Closed-loop system eliminates external contamination and scaling, ensuring 7×24h chip level reliability
♦ Compact modular design reduces footprint, suitable for prefabricated data centers

Single Phase Immersion Cooling + Closed Circuit Cooling Tower / Large Dry Cooler
Single- Phase Immersion Cooling Solution
Application scenarios: AI & HPC clusters, supercomputing centers, large scale IDCs
Single-phase immersion cooling directly immerses servers in a dielectric coolant that remains liquid. Heat from the chips is transferred from the coolant to a plate heat exchanger, and finally rejected by the outdoor cooling source. This solution can operate completely fan free, enabling silent, highdensity deployment.

Single-Phase Immersion Cooling Solution | Working Principle
► Recommended cooling source: Closed circuit cooling tower or large dry cooler (suitable for high power)
♦ Provides stable water supply with 5°C ΔT, supporting efficient heat exchange in the immersion system
♦ Compressor-free, PUE ≤ 1.1, more than 30% annual energy reduction
♦ Single-phase immersion fluid requires easy maintenance – no boiling pressure control concerns

Two Phase Immersion Cooling + Adiabatic Cooler
Two-Phase Immersion Cooling Solution
Application scenarios: Small to medium liquid cooling scenarios
Two-phase immersion cooling uses the boiling phase change of a dielectric fluid, removing a large amount of heat through latent heat of vaporisation. The generated vapour releases heat and condenses inside the condenser coil, and the heat is ultimately rejected by the outdoor cooling source. The efficient phase change heat transfer gives it the strongest heat density support capability, while also demanding the highest level of stability and temperature control accuracy from the cooling source.
Two-Phase Immersion Cooling Solution | Working Principle
► Recommended cooling source: NWFL-VA Series Adiabatic Cooler
♦ Adiabatic pre-cooling + dry-mode operation – compressor-free, PUE ≤ 1.05
♦ Fully utilises wet-bulb temperature throughout the year; total power consumption is only 1/3 of conventional chiller-based systems
♦ Pure dry operation in water-scarce regions – no water source burden, green and environmentally friendly
♦ Lightweight structure supports rooftop / edge site installation, ideal for retrofit and modular server rooms
