In today’s world of exponentially growing computing demand, traditional cooling technologies are struggling to meet the thermal management needs of modern Data Centers. Immersion cooling Technology has emerged as a revolutionary solution, redefining data center thermal management paradigms. This technology not only addresses the heat dissipation bottlenecks of high-density computing but also pioneers a new era where energy efficiency and performance coexist.

I. Technical Principle: A Qualitative Leap from “AIr Convection” to “Liquid Conduction”

The core breakthrough of immersion cooling lies in fundamentally altering the basic mode of heat transfer:

Limitations of Traditional Air Cooling:

• Relies on air convection, resulting in low thermal conductivity efficiency.
• Requires extensive ventilation systems and high-speed fans.
• Cooling effectiveness is strictly constrained by ambient temperature.
• Generates significant noise and energy waste.

Revolutionary Advantages of Immersion Cooling:

• Utilizes direct contact between coolant and heat-generating components.
• Liquid thermal conductivity is over 1000 times greater than air.
• Enables fanless, silent operation.
• Overcomes ambient temperature limitations, achieving precise temperature control.

This fundamental technological shift represents a qualitative leap in cooling efficiency, moving beyond incremental improvement.

II. Technical Implementation: Innovative Breakthroughs in Single-Phase and Two-Phase Systems

Single-Phase Immersion Cooling:

• Uses engineered fluids as the cooling medium.
• Achieves continuous heat removal through liquid circulation.
• Features a relatively simple and reliable system structure.
• Suitable for most application scenarios.

Two-Phase Immersion Cooling:

• Leverages the phase-change principle of the coolant.
• Liquid vaporization absorbs large amounts of heat.
• Vapor re-condenses in the condenser.
• Represents the pinnacle of heat removal efficiency.

These two technical approaches each have distinct characteristics, providing tailored solutions for different application scenarios.
