Modular Cooling Racks to Reduce Data Center Air Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional data center cooling systems, such as CRAC units, are inefficient due to the mixing of hot and cold air, require significant infrastructure setup, and pose risks with overhead piping, leading to inefficiencies and potential equipment damage.
Innovation Solution
A modular cooling system comprising flexible tubing and cooling racks that draw warm air from hot aisles, cool it, and exhaust it to cold aisles, with a distribution box and controller to manage coolant flow and environmental conditions, allowing for scalable and efficient cooling without the need for raised floors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If CRAC units are used to cool data centers, then cooling capacity is provided, but air mixing inefficiency occurs reducing cooling effectiveness
Solution Approach 1:
The data center cooling system is segmented into multiple independent cooling racks distributed throughout the facility, each handling local cooling needs rather than one or few centralized CRAC units. This segmentation prevents large-scale air mixing and allows precise temperature control in different zones.
Solution Approach 2:
Each cooling rack provides localized cooling to nearby equipment racks, creating temperature-appropriate zones throughout the data center. The system delivers cool air directly where heat is generated, eliminating the inefficiency of mixing hot and cold air in centralized systems.
2Ease of manufacture
If overhead piping is installed for coolant delivery, then cooling infrastructure is established, but reliability decreases due to potential joint failures and earthquake risks
Solution Approach 1:
The vulnerable overhead piping system with soldered joints is extracted and replaced with flexible tubing that connects cooling racks to coolant sources without requiring rigid overhead installations. This eliminates the reliability issues associated with joint failures and seismic activity.
Solution Approach 2:
Flexible tubing is used instead of rigid overhead pipes to deliver coolant to cooling racks. The flexibility of the tubing accommodates movement and eliminates the need for vulnerable soldered joints, significantly improving system reliability in earthquake-prone areas.
3Ease of manufacture
If raised floors are installed for coolant delivery, then cooling infrastructure is provided, but device complexity and floor space are increased
Solution Approach 1:
The raised floor infrastructure for coolant delivery is extracted and replaced with flexible tubing that can be routed through existing floor openings or along walls. This eliminates the need for complex raised floor constructions while maintaining coolant delivery capability.
4Adaptability or versatility
If modular cooling racks with flexible tubing are used, then scalability and safety are improved, but device complexity increases due to multiple components
Solution Approach 1:
The cooling system is divided into modular cooling rack units that can be independently installed, operated, and scaled. Each module contains essential cooling components, allowing flexible configuration and easy expansion without requiring complex integrated system design.
