Liquid Cooling Has Become a Standard for AI Data Centers — How Two-Phase Liquid Cooling Leads New Cooling Standards

I. Liquid Cooling: The Inevitable Choice for High-Density Computing Centers

With the explosive development of artificial intelligence, large models and high-performance computing scenarios, the heat load per cabinet in data centers is rising rapidly. In some scenarios, the power has exceeded tens of kilowatts. The heat dissipation capacity of traditional air cooling systems is approaching the physical limit, making it difficult to maintain stable equipment operation.Compared with air cooling, liquid cooling media have significant advantages in thermal capacity and thermal conductivity. They can directly approach heat sources such as chips for efficient heat dissipation, fundamentally solving the problem of high heat density.Meanwhile, driven by the 'dual carbon' goals and green data center policies, the market penetration of liquid cooling technology continues to increase, and the market scale is experiencing rapid growth. It has become the core cooling solution for high-density computing centers.

II. Two-Phase Liquid Cooling: A Breakthrough from “Cooling Down” to “Precise Temperature Control”

1. 1.Higher heat removal efficiency, easily handling high heat flux scenarios and quickly controlling peak heat loads.
2. 2.More stable temperature output, enabling precise regulation of the coolant phase-change process to prevent temperature overshoot or oscillation.
3. 3.Lower energy consumption and stronger reliability, greatly reducing reliance on air cooling equipment and computer room air conditioning (CRAC), further improving the overall energy efficiency of data centers.

3. Precise temperature control ensures core computing components such as CPUs and GPUs always operate within the optimal temperature range. This not only avoids computing power loss caused by thermal throttling, but also reduces thermal stress on hardware due to temperature fluctuations, significantly enhancing long-term equipment reliability and service life. This ultimately translates to higher equipment utilization and lower total cost of ownership.

Two-phase liquid cooling is not only energy-efficient itself, but also enables heat recovery and reuse—for example, by applying recovered heat to building heating. This reduces carbon emissions over the full life cycle and helps data centers achieve green and low-carbon operation.
