Find Innovative SolutionsGenerate Solutions
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 applies local quality by varying the cross-sectional area of different duct passages to match the non-uniform waste heat generation patterns of different rack systems. Each duct passage is tailored with specific dimensions to deliver appropriate cooling capacity to racks with different heat loads, thereby optimizing cooling efficiency while maintaining manageable system operation through a standardized adjustable duct design.
Solution Approach 2:
The patent employs dynamics by making the duct passages adjustable rather than fixed. The cross-sectional areas can be modified to adapt to changing computing capacities and heat generation patterns, allowing the cooling system to dynamically respond to varying thermal loads without requiring complete system redesign or complex control mechanisms.
2Productivity
If additional servers are added to increase computing capacity, then processing power increases, but cooling infrastructure requirements and operational complexity increase
Solution Approach 1:
The adjustable duct passages enable the cooling infrastructure to dynamically adapt to increased computing capacity by modifying cross-sectional areas to match new heat loads, avoiding the need for complete infrastructure redesign when adding servers.
Solution Approach 2:
The patent changes physical parameters of the cooling system by adjusting duct cross-sectional areas to match varying heat generation from additional servers, allowing capacity expansion without proportional increases in infrastructure complexity.
3Loss of energy
If existing cooling infrastructure is used for expanded computing capacity, then infrastructure investment is protected, but cooling effectiveness decreases
Solution Approach 1:
The adjustable duct passages allow the existing cooling infrastructure to be dynamically reconfigured to match new heat loads from expanded computing capacity, maintaining cooling effectiveness without requiring new infrastructure investment.
Solution Approach 2:
By changing the cross-sectional area parameters of the duct passages, the system adapts existing cooling infrastructure to new thermal conditions, preserving both investment efficiency and cooling reliability simultaneously.
