Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access floor systems in data centers inefficiently distribute cooling air from the plenum to IT racks, leading to inconsistent temperatures and increased energy costs due to vertical airflow patterns that do not effectively target the heat sources.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional vertical airflow patterns are used, then cooling air is supplied to the plenum, but the air does not effectively reach the heat sources in IT racks, resulting in inconsistent temperatures and increased energy consumption
Solution Approach 1:
The grate panel incorporates angled vanes with specific geometric configurations that create localized turbulent flow patterns. These vanes are positioned and angled to direct airflow specifically toward the front faces of IT racks where heat sources are located, rather than allowing uniform vertical dispersion. This localized flow directionality ensures cooling air reaches the heat sources effectively, resolving the contradiction between energy consumption and cooling efficiency
Solution Approach 2:
The invention changes the flow parameters by using angled vanes to transform laminar vertical airflow into turbulent flow patterns. The vanes are angled at specific degrees to alter the velocity distribution and flow direction, creating eddies and mixing that propel cooling air horizontally toward IT rack faces. This parameter transformation enables the cooling system to deliver air directly to heat sources, improving cooling efficiency without increasing energy consumption
2Temperature
If cooling air is distributed vertically through the plenum, then air flow is simple and direct, but temperature distribution across IT racks becomes inconsistent and heat sources are not effectively targeted
Solution Approach 1:
The grate panel is segmented into multiple angled vanes arranged in specific patterns. Each vane acts as an independent flow directing element, creating multiple localized turbulent zones that collectively distribute cooling air evenly across the IT rack array. This segmentation allows precise control over airflow patterns, achieving consistent temperature distribution while maintaining a relatively simple overall panel structure
Solution Approach 2:
The angled vanes create curved flow paths and turbulent eddies that redirect cooling air horizontally toward IT racks. The curved geometry of the vanes and the resulting flow patterns enable smooth redirection of air from vertical to horizontal movement, ensuring even temperature distribution across racks without requiring complex mechanical structures
3Productivity
If high velocity airflow is used to cool IT racks, then cooling effectiveness increases, but air velocity is not optimized and energy efficiency decreases
Solution Approach 1:
The invention uses passive pneumatic principles through the angled vane geometry to convert vertical air pressure into horizontal flow momentum. The vanes are shaped and angled to create pressure differentials that naturally drive air toward IT racks without requiring additional energy input. This pneumatic design optimizes airflow velocity and direction, achieving effective cooling while minimizing energy consumption

Function Achieved in This Case
The directional grate panel achieves consistent temperature distribution across IT racks by directing a higher percentage of cooling air directly to the racks, reducing energy consumption and minimizing wasted airflow, thus requiring less total airflow volume.
Implementation Method 1
The airflow through the plurality of spaced vanes results in more even distribution of air through the grate access floor panel
