Adjustable Air Shroud for 1U and 2U Server Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems require separate air shrouds for 1U and 2U enclosures, necessitating a dual inventory and potentially inefficient management of airflow direction in both configurations.
Innovation Solution
A single, adjustable air shroud design that can adapt to both 1U and 2U enclosures by adjusting its length through collapsible or deformable side portions, ensuring consistent airflow direction across varying enclosure sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate air shrouds are provided for 1U and 2U enclosures, then airflow direction is optimized for each specific enclosure type, but inventory complexity and component variety increase
Solution Approach 1:
The air shroud is designed with an adjustable portion that can be configured in different positions to accommodate both 1U and 2U enclosure types. This single universal air shroud replaces the need for separate dedicated air shrouds for each enclosure type, maintaining optimized airflow direction while reducing inventory complexity.
Solution Approach 2:
The air shroud incorporates an adjustable portion that can be dynamically repositioned between different configurations. This dynamic adjustment capability allows the same air shroud to adapt to different enclosure heights (1U and 2U), enabling a single component to perform multiple functions that previously required separate static components.
2Productivity
If a single adjustable air shroud is used for both 1U and 2U enclosures, then inventory efficiency improves, but device complexity increases
Solution Approach 1:
The air shroud is divided into distinct segments: a first portion for directing airflow through DIMMs, a second portion for directing airflow through the processor stack, and an adjustable portion that can be repositioned. This segmentation allows the adjustable portion to be independently modified without affecting the functional integrity of the fixed portions, enabling adaptability while maintaining structural simplicity.
Solution Approach 2:
Only the specific adjustable portion of the air shroud is designed to be reconfigurable, while the first and second portions maintain fixed, optimized structures for their respective airflow paths. This localized adaptability minimizes the increase in overall device complexity by limiting the adjustable features to only where needed, rather than making the entire air shroud complex.

AI summary
An air shroud is provided to direct air flow in an information handling system. The air shroud includes a first portion, a second portion, and an adjustable portion. The first portion directs the air flow through dual-inline memory modules of the information handling system. The second portion directs the air flow through a processor stack of the information handling system. The adjustable portion is coupled between the first portion and the second portion, and is configured to be adjusted to a first length when the information handling system is in a 1U enclosure, and to be adjusted to a second length when the information handling system is in a 2U enclosure.
