Modern data centers are continuously increasing server density to support cloud computing, artificial intelligence, high-performance computing, and mission-critical applications. As rack power densities rise, traditional cooling systems often struggle to manage the growing heat load efficiently. To address these challenges, Delta offers the COOLDOOR 30/50KW Rear Door Cooling Solution, an advanced cooling technology designed specifically for high-density server environments.
The Delta CoolDoor is a highly efficient rear door cooling unit equipped with electronically commutated (EC) fans that deliver exceptional cooling performance while maintaining low energy consumption. Installed directly at the rear of the server rack, the CoolDoor removes heat at the source before hot air can enter the data center environment. This approach significantly improves cooling efficiency and reduces the burden on traditional room-based cooling systems.
When integrated with Delta’s Coolant Distribution Unit (CDU) or chiller system, the CoolDoor provides a complete thermal management solution capable of supporting high-density IT loads while improving overall data center energy efficiency.
How Rear Door Cooling Works
Unlike conventional cooling systems that cool the entire room, Rear Door Cooling targets heat directly where it is generated.
The cooling process includes:
- Hot air exits the rear of the server rack.
- The CoolDoor heat exchanger captures the heat immediately.
- Chilled water circulating through the cooling coils absorbs the heat.
- EC fans optimize airflow across the heat exchanger.
- Cooled air is returned to the data center environment.
By removing heat before it spreads into the room, the system improves cooling effectiveness and helps maintain stable operating temperatures for critical IT equipment.
