Building a New Generation of Sustainable and Efficient Data Centers: Smart Cloud CDU × Immersion Cooling

In today’s era where AI, HPC, and ESG have become the three core drivers of enterprise digital transformation, data centers are no longer just “server rooms” for data storage — they have evolved into the computational and energy hubs of modern enterprises.

As computing density and power consumption continue to soar, traditional air and fan-based cooling methods can no longer meet the demands of modern data centers. Against this backdrop, Smart Cloud CDU combined with Immersion Cooling technology is ushering in a new chapter of smarter, quieter, and more energy-efficient operations.

Why Do Data Centers Need “Re-Cooling”?

In AI model training, semiconductor testing, and HPC environments, traditional air-cooling systems are reaching their limits in terms of heat dissipation efficiency, energy consumption, and carbon emissions.

According to a report by Persistence Market Research, the global data center liquid cooling market is expected to grow from USD 4.5 billion in 2025 to USD 21.8 billion in 2032, representing a CAGR of 25.3% — signaling that liquid cooling is rapidly becoming the mainstream cooling solution for data centers worldwide.

Today’s enterprises need more than just “cooling equipment”; they need an intelligent energy-management system capable of real-time monitoring, autonomous control, predictive maintenance, and ESG-integrated reporting — turning cooling into a key part of sustainable operations.

What Is Immersion Cooling?

Immersion Cooling is a next-generation, high-efficiency cooling technology for data centers. It works by submerging servers and electronic components in a non-conductive (dielectric) liquid coolant, which absorbs and transfers heat much more effectively than air. The heated liquid then circulates to a heat exchanger, where the heat is released before returning to the tank through a pump or natural convection — forming a highly efficient closed-loop cooling system.

Two Types of Immersion Cooling

1. Single-phase immersion cooling:

   The coolant remains in liquid form throughout the process. Cooling is achieved through liquid circulation and heat exchange. This approach is suitable for enterprise-grade data centers requiring stable, long-term operation.

2. Two-phase immersion cooling:

   The coolant partially vaporizes after absorbing heat and then condenses back into liquid on a condenser plate, creating a natural convection cycle. This method offers higher thermal efficiency and is ideal for high-density HPC and GPU AI-training workloads.

Advantages over traditional air cooling:

• Several times higher thermal conductivity — liquids transfer heat faster with smaller temperature differentials.

• Low noise and vibration — no need for massive fan arrays, ensuring quiet and stable operation.

• Exceptional energy efficiency — PUE values as low as 1.02–1.03, compared with ~1.5 in typical air-cooled data centers, improving overall efficiency by 40–50%.

Immersion cooling transforms cooling from an auxiliary mechanism into a core technology, enabling stable, high-performance, and energy-saving operation for data centers.

Smart Cloud CDU — Turning Cooling into Smart Energy

The Smart Cloud CDU (Cooling Distribution Unit) serves as the intelligent control hub of a liquid-cooling system. With cloud-based monitoring, AI analytics, and sensor networking, it makes data-center cooling learnable, predictable, and energy-efficient.

• Automated control: Adjusts water flow, pressure, and temperature in real time based on environmental conditions and workload.

• Cloud-centralized monitoring: Integrates CDU, UPS, PDU, CRAC units, cooling towers, and other subsystems.

• Energy transparency: Provides real-time PUE dashboards and carbon-emission reports to support corporate ESG goals.

• Modular scalability: Can expand flexibly from a single cabinet to a full data-center deployment while integrating with existing systems.

A Smart CDU is not just a cooling controller — it’s the “energy intelligence brain” of the data center. Every watt of energy and every drop of coolant is precisely managed and optimized, transforming cooling performance into sustainable competitiveness.

Smart Cloud CDU × Immersion Cooling — The Dual Power of Sustainable Cooling

When Smart CDU and Immersion Cooling technologies merge, the result is an integrated ecosystem driven by Smart Automation × Liquid Cooling × Cloud Management:

FUNCTION	SMART CLOUD CDU	IMMERSION COOING
Cooling Control	AI-driven adjustment of pumps, pressure, and flow rate	Direct heat absorption via liquid, ultra-efficient
Energy Maagement	Cloud monitoring of power use and carbon output	Reduces cooling power and lowers PUE
Predictive Maintenance	Data-trend analysis and early-warning detection	Reduces thermal fatigue and equipment failure
Environmental Sustainability	Automatic ESG reporting and performance analytics	Lowers carbon footprint, supports green transition

This integration not only optimizes data-center performance but also redefines the role of cooling technology as a key enabler of enterprise sustainability strategies.

Diverse Application Scenarios

🔹 AI / HPC Training Centers

High-speed GPU clusters generate significant heat loads when training large-scale AI models. The Smart CDU and immersion cooling system work collaboratively to maintain stable low temperatures, enhancing overall performance and computing efficiency.

🔹 Semiconductor and Wafer Testing Facilities

High-precision equipment requires strict temperature control. The intelligent liquid-cooling system can maintain temperature stability within ±0.3 °C, effectively improving test yield rates and production consistency.

🔹 Smart Medical Data Centers

Genomic computation and medical-image analysis demand long hours of continuous operation. The silent and dust-free liquid-cooling environment ensures consistent performance while significantly reducing power consumption.

🔹 Edge and Urban Data Centers

In space-constrained high-rise buildings and 5G base-station environments, modular CDU + liquid-cooling solutions enable rapid deployment, achieving efficient heat dissipation and intelligent remote management.
