Dynamic Impedance Blank Cartridge for Blade Enclosure Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blank cartridges in blade enclosures have fixed impedance, leading to inefficient cooling and increased energy consumption due to the need for higher fan or pump speeds to compensate for fixed airflow resistance, which is not effectively directed to computing components.
Innovation Solution
Incorporating an impedance portion with an actuator in blank cartridges that can dynamically change impedance levels based on the location and configuration of computing components relative to the blank cartridges, allowing for optimized airflow or coolant flow management through the use of a management controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed impedance is used in blank cartridges, then manufacturing simplicity is maintained, but cooling efficiency deteriorates and energy consumption increases
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed impedance structure into a dynamic, adjustable impedance structure. The blank cartridge includes an impedance adjustment mechanism that can change the impedance level based on the actual cooling needs and component locations, allowing the system to adapt rather than remain static. This resolves the contradiction by enabling energy-efficient cooling while maintaining manufacturing feasibility through a modular adjustment mechanism.
Solution Approach 2:
The patent implements parameter changes by allowing the impedance parameter of the blank cartridge to be dynamically adjusted rather than fixed. The impedance level can be changed based on the positions of computing components and cooling requirements, enabling the system to optimize cooling efficiency for different configurations without requiring complete redesign of the blank cartridge structure.
2Device complexity
If fixed impedance is used in blank cartridges, then device complexity is reduced, but cooling performance deteriorates
Solution Approach 1:
The patent transforms the static impedance structure into a dynamic one with adjustment capabilities. The impedance adjustment mechanism allows the blank cartridge to adapt its impedance level based on real-time cooling requirements and component positions, significantly improving cooling performance while adding only moderate complexity through a controlled adjustment system.
Solution Approach 2:
The patent implements feedback control by monitoring the positions of computing components and the actual cooling performance, then using this information to automatically adjust the impedance level of the blank cartridge. This feedback mechanism ensures optimal cooling performance is maintained while the complexity is managed through automated control rather than manual intervention.
3Reliability
If higher fan or pump speeds are used to compensate for fixed airflow resistance, then cooling capacity is maintained, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by enabling the impedance to be adjusted in real-time based on cooling needs. Instead of always operating at high fan or pump speeds to overcome fixed high impedance, the system dynamically adjusts impedance to match actual requirements, maintaining cooling capacity while significantly reducing the energy needed for airflow generation.
Solution Approach 2:
The patent changes the impedance parameter dynamically to optimize the balance between cooling capacity and energy consumption. By adjusting impedance rather than always increasing fan/pump speed, the system achieves the same cooling effect with lower energy input, as the airflow resistance is optimized rather than overcome through brute-force high-speed operation.
