Rack Enclosure Side Plenums for Chassis Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal management techniques in computing centers are limited by the width of the chassis for air cooling, which restricts the number and size of computing components that can be housed, leading to potential overheating and equipment failure.
Innovation Solution
The implementation of side plenums and front perforations in a rack enclosure allows air to flow along the sides of the chassis, reducing the width required for air intakes and enabling more efficient cooling by directing ambient air into the chassis through side openings, thereby maximizing the number of components that can be housed while maintaining effective temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional thermal management techniques are used with limited air cooling within chassis width, then cooling effectiveness is maintained, but the number and size of computing components that can be housed is restricted
Solution Approach 1:
The patent introduces side plenums located at the sides of the chassis, creating a new spatial dimension for air cooling flow. Instead of relying solely on front-to-back air intake within the chassis width, the side plenums provide lateral air pathways that extend the cooling volume beyond the traditional chassis boundaries, enabling more components to be housed while maintaining effective heat dissipation
2Quantity of substance
If the chassis width is increased to accommodate more components, then the number of computing components increases, but the space available for air intakes and cooling pathways is reduced
Solution Approach 1:
By utilizing the side dimensions of the rack enclosure through side plenums, the patent creates additional cooling pathways that do not compete with the front air intake area. This lateral expansion of the cooling volume allows the chassis width to be optimized for component density while the side plenums provide the necessary air flow pathways independently
Solution Approach 2:
The cooling system is segmented into multiple independent pathways: front air intakes for primary cooling and side plenums for auxiliary cooling. This segmentation allows each pathway to be optimized independently, with the side plenums providing additional cooling capacity without requiring increased front intake area
3Quantity of substance
If side plenums are implemented to expand cooling volume, then more computing components can be housed, but the rack enclosure structure becomes more complex
Solution Approach 1:
The side plenums serve multiple functions: they provide auxiliary cooling pathways, maximize the utilization of rack enclosure space, and enable higher component density. By integrating these plenums into the existing rack structure, the design achieves multi-functionality without proportionally increasing complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the space needed for air intakes within the chassis, allowing for a greater number of computing components to be accommodated while maintaining reliable thermal management and preventing overheating, thus enhancing the functionality and reliability of the computing center.
Implementation Method 1
The rack enclosure may include side plenums that provide an air pathway to route the cooling air as it flows along the side surfaces of the chassis and into the chassis

AI summary
The present examples include a rack enclosure with perforations formed within vertical rack columns. Front vertical rack columns may include front perforations formed therein. The front perforations may draw air into the rack enclosure and further into a chassis. Side plenums along the side surface of the chassis may consume less space with the use of the front perforations. The space not consumed by the side plenums may be available to accommodate a chassis of a substantial volume. The chassis may expand a substantial width of the rack enclosure to house an enlarged or a maximum number of computing components within the rack enclosure.
