How to choose liquid cooling data center companies?

Choosing liquid cooling data center companies requires a comprehensive evaluation of its technological maturity, full stack service coverage, and landing experience in the target industry. Priority should be given to top enterprises that can provide customized solutions, have large-scale project experience, and strong ecological collaboration capabilities.
1、 Technical roadmap: Focus on mainstream paths while considering future compatibility
Cold plate liquid cooling is currently the optimal solution, with a market share of 91%
Cold plate has become the mainstream in the current market due to its smooth deployment and strong compatibility, especially suitable for high-density computing scenarios. When choosing, the focus should be on whether the manufacturer has the ability to independently design cold plates (such as microchannel structure optimization), whether the heat transfer coefficient meets the standard (>8000 W/m ² K is preferred), and supports multi brand server adaptation.
Immersion represents the future direction, but risks and costs need to be evaluated
Fully submerged heat dissipation has higher efficiency and is suitable for extreme load scenarios such as supercomputing and AI training. However, attention should be paid to the environmental friendliness of the coolant (avoiding the presence of persistent pollutants such as PFAS), leakage prevention mechanisms, and ease of operation and maintenance. It is recommended to prioritize enterprises that have already conducted pre research on phase change cooling technology to ensure technological foresight.
Spray type applications are rare, choose non mainstream solutions carefully
Spray type renovation has high costs and few implementation cases. Currently, it is limited to specific laboratory environments and has low commercial maturity. It is not recommended as the first choice.
  Suggested action: Request manufacturers to provide third-party testing reports and actual PUE data (ideal value ≤ 1.15), and confirm whether their technical roadmap is included in the recommended system of the three major operators’ “Liquid Cooling Technology White Paper”.
2、 Service scope: From a single device to end-to-end full stack delivery
Preferred manufacturers with integrated capabilities of “hardware+system+operation and maintenance”
A true full stack service provider can not only provide liquid cooled servers CDU、 Core components such as coolant can also integrate monitoring systems, intelligent control platforms, and support later operation and maintenance hosting. For example, Zhongke Shuguang provides a collaborative solution of “computing power equipment+liquid cooling technology” through its subsidiary Shuguang Shuchuang, achieving integrated software and hardware delivery.
Focus on the self-developed capability of key subsystems
Coolant: Kaisheng Fluorine Chemical, a subsidiary of Juhua Group, has the ability to mass produce electronic fluorinated liquids and is a key barrier link in the industry chain.
Circulating pump: Feilong Co., Ltd. provides CDU specific pumps for liquid cooling systems to ensure fluid stability.
If the core components such as quick connectors (UQDs) rely on imports, it may affect the delivery cycle and maintenance response speed.
Modular and Scalable Design
Choose a solution that supports plug and play modular architecture for easy expansion and device replacement in the future. Huawei, Tsinghua Unigroup, and other companies have launched liquid cooling products for whole machine cabinets, which support rapid deployment and hot swappable maintenance.
