Solution Overview
Problem
Existing data center cooling systems face inefficiencies due to non-uniform waste heat generation across rack systems, leading to suboptimal air cooling distribution and increased operational costs, especially when rapid changes in computing capacity are needed.
Innovation Solution
A system utilizing a soft duct with a variable cross section control device, equipped with a motor and constricting member, allows for dynamic adjustment of air flow by altering the cross-sectional area of the duct passages to efficiently distribute cooling air to rack computing systems, accommodating varying heat loads and capacity expansions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform heat removal methods are applied to non-uniform waste heat generation sources, then installation and operation are simplified, but cooling efficiency decreases
Solution Approach 1:
The patent implements variable air flow control that delivers different cooling rates to different rack systems based on their specific heat generation characteristics. Each rack system receives customized cooling air flow proportional to its waste heat generation, transforming the uniform cooling approach into a localized, adaptive solution that matches actual thermal loads.
2Productivity
If additional servers are added to increase computing capacity, then processing capability is improved, but cooling infrastructure requirements increase
Solution Approach 1:
The patent employs dynamically adjustable air flow control mechanisms that can be modified in real-time based on changing computing loads. When servers are added or removed, the system automatically adjusts cooling air distribution without requiring physical infrastructure changes, enabling flexible scaling of both computing and cooling capacities.
Solution Approach 2:
The system changes operational parameters (air flow rates, duct configurations) rather than physical infrastructure when computing capacity needs to be adjusted. By modifying control parameters in response to changing server configurations, the system accommodates capacity expansion without proportional increases in cooling infrastructure complexity.
3Temperature
If forced air systems are used to maintain temperature, then cooling effectiveness is improved, but operational costs increase
Solution Approach 1:
The patent incorporates feedback mechanisms that monitor actual thermal loads and adjust air flow accordingly. By continuously measuring heat generation from rack systems and responding with appropriate cooling air distribution, the system avoids over-cooling low-load areas while ensuring adequate cooling for high-load areas, optimizing energy utilization.
Solution Approach 2:
The system applies cooling air selectively and proportionally to actual heat generation needs rather than uniformly across all areas. By delivering cooling air only where and in the amount needed based on measured thermal loads, the system avoids excessive cooling in low-demand areas, reducing overall energy consumption while maintaining effective temperature control where required.
