Reliability and durability test

Test Background

The CDU needs to operate continuously for a long time. Core components such as pumps, valves, and heat exchangers may experience performance degradation or failure during continuous operation. Reliability verification is the key to ensuring the stable operation of the system throughout its life cycle.

Test Introduction

Through projects such as aging tests, redundant switching tests, and power-off protection tests, simulate the performance of the CDU under long-term operation and fault modes to verify its reliability and fault tolerance.

Testing Objectives

Verify the stability of continuous operation for more than 72 hours

Ensure automatic redundant switching in case of pump/heat exchanger failure

Test the system's ability to maintain and recover its state after a power outage

Evaluate the reliability index (MTBF) throughout the life cycle

Test Standards

T/CESA 1249.3-2023 Technical specification for cooling capacity distribution units

FAQ
Q: Will the server operation be affected during CDU redundant switching?
A: High-quality CDUs can achieve seamless switching. During the switching process, the pressure/flow fluctuation is controlled within ±5%, which has no impact on the server.
