Heated Air Staging Chamber for Server Rack Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data center cooling systems face inefficiencies in heat removal due to server racks being back-to-back, requiring excessive fan effort to push hot air, and lack of redundancy in cooling capacity.
Innovation Solution
A chamber is provided to mix, channel, and diffuse heated air from server racks to a heat removal cabinet, with configurable diffusion angles and redundant cooling capacity through additional cabinets, using refrigerants with low ozone depletion potential.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If server racks are placed back-to-back in a narrow space, then space utilization is improved, but fan workload increases excessively to push hot air
Solution Approach 1:
A heat staging chamber is introduced as an intermediary component between the server racks and cooling systems. This chamber receives hot air from multiple racks, mixes and diffuses it, then channels it to heat removal cabinets. This intermediary structure eliminates the need for high fan pressure in narrow back-to-back configurations while maintaining effective heat removal.
2Temperature
If cooling capacity is increased to handle all heat, then temperature control is improved, but system complexity and cost increase
Solution Approach 1:
The heat removal system uses adjustable diffusers with configurable angles that can be manually or automatically adjusted. This dynamic adjustment capability allows the system to optimize airflow patterns and cooling capacity based on actual heat loads, providing temperature control without requiring a fixed high-capacity cooling system.
Solution Approach 2:
The cooling system is divided into modular heat removal cabinets that can be individually adjusted and configured. Each cabinet handles a specific zone or rack group, allowing incremental scaling and simplified maintenance compared to a monolithic cooling system.
3Reliability
If redundant cooling capacity is added, then reliability is improved, but device complexity increases
Solution Approach 1:
The heat staging chamber and diffuser system serve multiple functions: they mix and diffuse hot air from various racks, channel it to appropriate heat removal cabinets, and provide configurable airflow patterns. This multi-functionality reduces the need for separate dedicated systems for each rack, simplifying the overall redundant configuration.
