Liquid cooling is becoming increasingly important in data centers. As performance and efficiency requirements continue to rise, the question of how media-carrying components can be reliably tested and validated is also moving into focus. Interestingly, the requirements are very similar to pressure testing in e-mobility. Here, too, cooling circuits are exposed to various pressure and temperature conditions.

This is exactly the topic of our technical article, “Testing Technology for Liquid-Cooled Server Components,” published in DataCenter-Insider. The article explains why realistic test conditions are central to liquid-cooling applications and what requirements they impose for evaluating components.

Typically, media-carrying components are exposed to pulsating pressures, for example, from 1 to 4 bar, while both the environment and the test medium, such as PG25, are temperature-controlled between -10 °C and 65 °C.

Our Pressure Test Benches for This Application

For these tasks, Poppe + Potthoff Maschinenbau develops customer-specific pressure test rigs for burst, leak, and fatigue testing of fluid-carrying components. Depending on the requirements, real media, defined pressure profiles, temperature conditions, and individual test cycles can be reproduced. This results in test setups that closely reflect the later application and enable reliable conclusions about function, leak-tightness, and durability.
