CDU COLD LIQUID DISTRIBUTION UNIT FINISHED PRODUCT AGING

The Cold Liquid Distribution Unit (CDU) finished product aging test system is designed to perform aging tests on the electrical components of assembled CDU products. By heating the liquid at a constant power using a thermostatic water tank and circulating it with the CDU, the system checks whether the internal water pump and fan of the CDU operate normally.

The Cold Liquid Distribution Unit (CDU) finished product aging test system is a platform designed to evaluate the performance stability and reliability of CDUs over extended operational periods. Below, we will delve into the details of this system:

Performance Testing

Pressure Resistance Test: Verifies the structural integrity and sealing capability of the CDU under high-pressure conditions, ensuring there are no leaks or damage in extreme situations. Weld Quality Inspection: Checks the quality of welding joints to prevent leakage due to poor welding, ensuring long-term stable operation of the system. Leakproof Test: Conducts pressure retention tests to detect the sealing performance of the CDU, ensuring there is no air or liquid leakage. Pipeline Cleaning Process Test: Simulates the actual pipeline cleaning process to verify its effectiveness and impact on system performance. Quick Connector Leak Test: Examines the sealing and durability of quick connect components under frequent plugging and unplugging operations. Accessory Installation Quality Test: Assesses the installation quality and functionality of auxiliary components such as sensors and filters. Functional Testing

Automatic Air Vent Functionality: Validates whether the automatic vent can effectively expel air from the system under various working conditions, preventing air blockage. Leak Detection Function: Through sensor monitoring and alarm systems, it detects and reports any potential liquid leaks in real time. Condensation Prevention Test: Ensures proper internal environmental control within the CDU to prevent condensation, protecting electronic equipment from damage. ATS Function: Verifies the functionality and reliability of the automatic transfer switch, ensuring rapid switching to backup power in case of main power failure. Inverter Functionality Test: Checks the adjustment capability and efficiency of the inverter to ensure it can adjust pump speed according to load changes, optimizing energy consumption. Safety Regulation Testing

Insulation Resistance Test: Measures the insulation resistance value of the CDU to ensure good electrical safety. Insulation Impedance Test: Evaluates the insulation strength between different parts of the CDU to prevent electrical short circuits. Dielectric Withstand Test: Conducts high voltage testing on the CDU to verify its safety and stability under overvoltage conditions. Maintainability Testing

Air Vent Online Replacement Function Test: Simulates actual maintenance scenarios to test if the air vent can be replaced smoothly without shutting down the system. Filter Online Maintenance and Replacement Function Test: Verifies whether the filter can be conveniently replaced and maintained without affecting the normal operation of the system. Overall, these tests not only help identify potential design flaws and manufacturing issues but also ensure that the CDU meets expected performance standards before actual deployment. For data center operators, selecting the appropriate CDU product and conducting thorough testing verification are crucial steps to ensure efficient and reliable operation of the data center.
