Adjustable Airflow Apparatus for Server Chassis Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer chassis designs inefficiently direct airflow to computer components due to gaps between components and slot edges, leading to overheating, especially when components are smaller than the slots or when multiple slots share common cooling fans, resulting in airflow being redirected into empty spaces rather than the components.
Innovation Solution
An adjustable apparatus with a base portion and bendable arms that couple with the server or chassis wall, allowing the arms to adjust their position based on the size and height of the computer components in each slot to maximize airflow direction over the components, reducing airflow leakage into empty spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional fixed slots are used to hold computer components, then the chassis structure is simple and easy to manufacture, but airflow is redirected into empty space when components are smaller than the slot, reducing cooling efficiency
Solution Approach 1:
The patent applies the dynamics principle by transforming the static, fixed slot structure into a dynamic system with movable arms that can adjust their position. The arms are positioned adjacent to each slot and can move to align with the actual computer component size, allowing the cooling system to adapt dynamically to different component configurations and maximize airflow efficiency.
Solution Approach 2:
The patent applies local quality by providing individual adjustable arms for each slot rather than a uniform fixed structure. Each arm can be independently positioned to match the specific component in its slot, creating localized airflow optimization for each component while maintaining the overall chassis structure.
2Adaptability or versatility
If slots are designed to accommodate various component sizes, then adaptability is improved, but airflow is wasted in empty spaces between components and slot edges
Solution Approach 1:
The movable arms provide dynamic adaptation to different component sizes while preventing airflow waste. By adjusting the arm position to match the component width, the system maintains adaptability across various component configurations while eliminating the empty space problem that causes airflow loss.
Solution Approach 2:
The adjustable arms act as intermediary elements between the fixed chassis structure and the variable-sized computer components. These arms fill the gap between the component edges and slot boundaries, serving as a mediator that directs airflow onto the component surface rather than allowing it to escape into empty space.
3Device complexity
If multiple slots share common cooling fans, then the cooling system is simplified, but airflow is redirected towards empty space instead of flowing over all computer components
Solution Approach 1:
The patent applies segmentation by dividing the common airflow from shared cooling fans into distinct directed streams for each slot. The movable arms segment the airflow path, ensuring that air flowing from common fans is properly distributed and directed onto each specific component rather than mixing and escaping into empty spaces.
Solution Approach 2:
The dynamic positioning of arms for each slot allows the cooling system to maintain simplified common fan architecture while achieving effective coverage of multiple components. The arms dynamically adjust to guide airflow from shared fans onto each component surface, maintaining cooling coverage efficiency despite the simplified cooling system structure.
