GTESTS Launches Professional Performance Test Bench for Full-Condition Liquid Cooling CDU Verification
As the core hub of the entire liquid cooling ecosystem, the Cooling Distribution Unit (CDU) undertakes critical system-level thermal management tasks including primary and secondary medium heat exchange, precise flow distribution, and stable pressure regulation. Although it does not directly contact server chips, the operational accuracy, heat exchange efficiency, flow stability, and pressure resistance of the liquid liquid cooling CDU fundamentally determine the safety, stability, and continuous operational reliability of high-performance computing and data center liquid cooling systems. Rigorous performance verification throughout CDU R&D and factory inspection phases is therefore essential to eliminate potential operational risks and ensure consistent product quality for industrial and AI computing scenarios.
To address the industry demand for standardized and accurate CDU performance verification, GTESTS has officially launched a professional CDU performance test bench, delivering comprehensive full-condition verification solutions for liquid cooling equipment manufacturers, research institutes, and third-party testing laboratories. This professional testing platform is fully compatible with mainstream hybrid cooling hardware and can complete multi-dimensional performance validation for the air liquid CDU cooler under simulated real-site operating conditions. It covers core testing items such as heat exchange capacity, temperature and pressure flow control accuracy, medium compatibility, and electrical performance, supporting iterative product optimization and standardized factory acceptance.
GTESTS’s CDU performance test bench is equipped with dual independent primary and secondary circulating systems to fully restore real data center operating environments. The primary loop adopts pure water or PG25/EG25 antifreeze as the circulating medium, supporting a temperature range of 25℃ to 60℃ with a high precision of ±0.2℃ and a maximum cooling capacity exceeding 2800kW, alongside a 10–240m³/h adjustable flow range and high-accuracy pressure monitoring. The secondary loop covers a temperature range of 30℃ to 70℃ with a 2600kW heating power rating, fully matching the operating parameters of mainstream air liquid CDU cooling unit products. The dual-loop synchronous simulation enables highly restored temperature, flow, and pressure working conditions for accurate and reliable performance testing.
Featuring highly compatible medium adaptation and full-scenario condition simulation, the test bench supports two mainstream cooling media: pure water and PG25/EG25 antifreeze. It can comprehensively verify key performance indicators of data center air liquid CDU, including temperature control stability, flow regulation characteristics, differential pressure performance, and operating power consumption under actual data center load conditions. All test data can be automatically recorded, sorted, and exported to form standardized test reports, providing authoritative data support for product R&D iteration, type inspection, and factory delivery acceptance for data center liquid cooling equipment.
The test bench adopts a fully intelligent measurement and control system with industrial computer automatic operation and optional manual independent control of pumps, valves, and heating units. It integrates visualized human-machine interfaces, professional test formula management, fully automatic test processes, comprehensive safety alarm mechanisms, and remote fault diagnosis functions. As a professional custom liquid cooling CDU manufacturer oriented testing solution, the platform supports one-click calling of customized test parameters, full-time data tracing, and unattended long-term testing, greatly improving testing efficiency and standardizing the verification process for customized CDU products of different specifications.
GTESTS’s CDU test bench is optimized for ultra-high heat flux computing scenarios and perfectly adapts to the performance verification requirements of high-end computing hardware. Its high-precision temperature control system achieves 0.2℃ steady-state temperature accuracy through non-contact silicon controlled power regulation, fully meeting the stringent thermal control standards of AI GPU liquid cooling CDU. The multi-level safety protection system covers liquid level monitoring, over-temperature and over-pressure automatic shutdown, leakage prevention, and complete electrical fault protection, ensuring stable and safe long-cycle testing for high-power AI liquid cooling CDU equipment.
The hardware and structural design of the test bench focus on long-term stability and industrial adaptability. All fluid pipelines and medium-contact components adopt 316L stainless steel with non-welded connection technology to effectively prevent liquid leakage, corrosion, and pipeline aging. Core components including sensors, pump valves, PLC controllers, and frequency converters adopt industry-leading reliable brands. The overall system is tailored for high-load testing of high density server liquid CDU, with multi-stage quality control including solution review, factory pre-acceptance, and on-site final acceptance, ensuring ultra-high testing accuracy and equipment durability.
Liquid cooling has become the core infrastructure supporting the large-scale development of AI computing centers, and standardized CDU performance verification is a key link in promoting the high-quality upgrading of the liquid cooling industrial chain. As a professional and reliable liquid cooling CDU solution provider, GTESTS leverages years of accumulated experience in fluid detection equipment R&D, innovatively applying multi-field coupling testing technology to CDU professional verification. The self-developed CDU performance test bench advances quality verification to the early R&D stage, effectively eliminates product hidden dangers, and empowers the overall quality improvement and standardized development of the domestic and global liquid cooling industry.
