Server Air-Duct Module with Integrated Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Server chassis face challenges in efficiently removing heat and routing cables due to limited space and increased power consumption, which complicates the integration of fans, air ducts, and cables within the confined volume.
Innovation Solution
An air-duct module with integrated cable-routing channels that guides air across heat exchangers while providing channels to manage and retain cables, featuring clamping structures and support bosses for secure cable retention and structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional separate air ducts and cable routing structures are used, then cable management is possible, but the device complexity increases and available space decreases
Solution Approach 1:
The patent combines the air duct and cable routing structures into a single integrated module. The air duct body includes recesses that form cable routing channels, eliminating the need for separate cable management components. This merging reduces structural complexity while maintaining both air flow guidance and cable organization functions within the same component.
2Temperature
If more fans and air ducts are added to improve cooling, then heat removal efficiency increases, but the volume occupied by cooling components increases
Solution Approach 1:
The air duct module performs multiple functions simultaneously: it guides air flow across heat exchangers for cooling, routes cables through integrated channels, and provides structural support. This multi-functionality allows the same component volume to serve both thermal management and cable management purposes, reducing the total volume required for cooling components.
3Ease of operation
If cables are routed through the air duct interior, then cable routing is achieved, but air flow efficiency may be compromised
Solution Approach 1:
The air duct is segmented into multiple recesses, with each recess forming a separate cable routing channel. These recesses are positioned such that cables can be routed through them without blocking the main air flow path. The segmentation allows independent cable routing in specific zones while preserving air flow efficiency in other zones.

AI summary
An air-duct module for a server comprises a main body that includes an upper wall and a plurality of side walls extending downwardly away from the upper wall. The main body further includes a plurality of channel walls extending from the upper wall and defining a cable-routing channel located within the main body. The cable-routing channel receives an electronics cable that extends across the main body. The air-duct module has an air passage for guiding air across a heat exchanger within the server. The air-duct passage is defined by the upper wall, the plurality of side walls, and at least some of the plurality of channel walls.
