Data Center Cooling System

Fan Applications and Selection in Data Centers
In data centers, fans are the lifeline for maintaining the stable operation of servers and network equipment. Since servers generate a significant amount of heat, efficient heat dissipation is crucial to prevent overheating, performance degradation, and even system crashes.

In practical scenarios, fans are widely applied in:

Server cabinet internal cooling: Each server typically has built-in small fans (like axial fans or centrifugal fans) that directly cool heat-generating components such as CPUs and GPUs.

In-row or in-rack cooling units: These units deliver cold air directly to server cabinets and draw hot air away using internal fans. EC fans are commonly used here due to their energy efficiency and precise speed control advantages.

CRAC/CRAH (Computer Room Air Conditioner/Air Handler): Large data centers rely on these units for overall room temperature and humidity management. They typically integrate large-volume, high-static-pressure centrifugal fans to ensure effective cold air circulation.
