As the industry′s demand for higher chip performance continues to rise, thermal management has become a significant challenge. This is particularly evident in legacy data centers, where traditional cooling methods—such as fans or cold plates combined with aluminum fins—often result in a combination of large physical footprints and low thermal dissipation efficiency. In contrast, CDUs offer significantly superior cooling capabilities compared to conventional air-to-water cooling methods. However, they also introduce potential leakage risks. Through experimental testing, this study evaluates the thermal dissipation performance of CDUs under varying heat loads and assesses various system indicators. It also analyzes potential issues within the equipment, such as blockage or overpressure protection interruptions. Results indicate that CDUs perform remarkably close to design expectations under rated conditions. Furthermore, when IT equipment operates under overload or excessive heat conditions, CDUs can adapt promptly and provide the necessary cooling efficiency. The study confirms that CDUs demonstrate a significant advantage in terms of space efficiency for a rated capacity of 1MW, compared to traditional fan-based cooling systems. Moreover, CDUs can accommodate a broader range of heat dissipation requirements.
