Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems, such as server racks, face reduced air flow efficiency due to high air flow impedance caused by storage device and carrier designs, leading to suboptimal cooling and increased power consumption for cooling fans.
Innovation Solution
Incorporating air channels within the storage devices and carriers by using cutout portions in the back wall and ribs, as well as a gasket with air channels, to reduce air flow impedance and enhance cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If storage devices and carriers are designed with solid structures, then structural strength is improved, but air flow impedance increases
Solution Approach 1:
The patent applies porous material principles by incorporating air channels through cutout portions in the back wall and ribs of storage devices and carriers. These cutout portions create a porous-like structure that allows air flow through the otherwise solid components, reducing air flow impedance while maintaining structural integrity through the carefully designed channel geometry and distribution.
2Productivity
If cooling fan speed is increased, then cooling efficiency is improved, but power consumption increases
Solution Approach 1:
The patent extracts the air flow resistance from the system by incorporating cutout portions that create dedicated air channels. By removing the impedance-causing solid structures in critical flow paths and replacing them with channelled openings, the system achieves better cooling efficiency without requiring increased fan speed, thus reducing power consumption.
3Use of energy by moving object
If air flow pressure is decreased, then power consumption is reduced, but cooling efficiency worsens
Solution Approach 1:
The air channels created by cutout portions in the back wall and ribs act as intermediary flow paths that guide air flow efficiently through the storage devices and carriers. These channels serve as mediators between the cooling fan and the heat-generating components, ensuring adequate cooling efficiency is maintained even at lower air flow pressure conditions by reducing turbulence and flow resistance.

AI summary
A storage device includes a first portion including drive media, and a second portion. The second portion includes a first end wall that is in physical communication with first and second side walls, and a second end wall that is in physical communication with the first and second side walls. The second portion also includes a printed circuit board mounted within the cavity, a plurality of ribs within the cavity, and an air channel within the cavity. The air channel has a lower air flow impedance than other portions of the storage device including the first portion, the printed circuit board, and the ribs. The air channel extends along a direction between the first end wall and the second end wall of the storage device.
