Movable Electronics Rack Containment for Dynamic Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aisle containment systems in data centers are inflexible and may not provide sufficient cooling for high-power density electronics racks, as they are integrated into the data center layout and have predefined cooling capacities that do not adapt to varying air cooling needs.
Innovation Solution
A reconfigurable containment system for electronics racks that includes a top structure and side structures movably coupled to the racks, allowing for the creation of containment regions that can be adjusted based on the thermal needs of adjacent clusters, using rails and moving mechanisms to position the structures and manage airflow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional aisle containment systems are integrated into the data center layout, then the cooling capacity is predefined and stable, but the system cannot adapt to varying air cooling needs of high-power density electronics racks
Solution Approach 1:
The containment system employs movable structures that can be dynamically repositioned along rails to adjust containment regions. The side structures and top structures are coupled to electronics racks through movable connections, allowing the system to adapt its configuration based on thermal needs while maintaining operational flexibility.
Solution Approach 2:
The containment system is divided into separate movable components including side structures, top structures, and containment regions that can be independently positioned. This segmentation allows each component to be adjusted separately to create customized containment layouts for different thermal environments.
2Adaptability or versatility
If movable structures are added to create reconfigurable containment regions, then adaptability to thermal needs is improved, but the device complexity increases
Solution Approach 1:
The movable structures serve multiple functions: they define containment region boundaries, guide airflow patterns, and can be repositioned to accommodate different rack configurations. The same structural components perform both structural support and airflow management functions, reducing the need for additional specialized parts.
Solution Approach 2:
The containment structures utilize panel-based designs that can be moved and reconfigured. These panel structures provide flexible containment boundaries that can adapt to different spatial requirements while maintaining the necessary sealing for effective thermal management.
3Temperature
If containment structures extend beyond rack ends, then cooling coverage is improved, but the risk of structures colliding with adjacent racks increases
Solution Approach 1:
The system incorporates sensors that detect the presence and position of adjacent racks before movable structures are actuated. This preliminary detection prevents structures from moving into positions that would cause collision with neighboring racks, ensuring safe operation while maintaining cooling effectiveness.
Solution Approach 2:
The containment system uses sensor feedback to monitor the position of movable structures and the location of adjacent racks in real-time. This feedback mechanism allows the system to adjust structure positions dynamically, extending cooling coverage when safe and retracting when collision risk is detected, thereby balancing cooling effectiveness with operational safety.

AI summary
According to one embodiment, a containment system for an electronics rack that includes a top structure that is movably coupled on top of the electronics rack, a first side structure that is movably coupled to a first side of the electronics rack, and a second side structure that is movably coupled to a second side of the electronics rack that is opposite to the first side, each of the structures is arranged to move along an axis and at least partially beyond either a front end or a back end of the electronics rack creating a containment region that is at least partially surrounded by the top structure, the first side structure, and the second side structure.
