Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Server designs that accommodate a greater number of hard disks often fail to provide adequate heat dissipation, leading to inefficiencies in thermal management.
Innovation Solution
A chassis structure with two partitions dividing the receiving space into a middle cavity and two side cavities, equipped with fan components and tray components that form parallel air ducts to enhance airflow and heat dissipation, while maintaining a balanced air pressure through strategically placed air vents and sliding, rotatable tray components to manage hard disk density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If hard disk density is increased to accommodate more hard disks in smaller servers, then storage capacity is improved, but heat dissipation performance deteriorates
Solution Approach 1:
The receiving space is segmented into multiple cavities (first cavity, second cavity, third cavity) using partitions. This segmentation allows independent airflow control in each cavity, enabling effective heat dissipation even with high hard disk density. Each cavity can be equipped with dedicated fan components to manage thermal zones separately.
Solution Approach 2:
Different regions of the chassis are assigned different functions: side cavities are optimized for hard disk storage and cooling, while the middle cavity is dedicated to power supply placement. Air inlets and outlets are strategically positioned at specific locations to create localized airflow patterns that target heat-generating components effectively.
2Volume of moving object
If tray components are placed closely to maximize space utilization, then device compactness is improved, but airflow control and heat dissipation deteriorate
Solution Approach 1:
The chassis is divided into distinct cavities that separate airflow paths. Even though tray components are densely packed, the partitions ensure that airflow channels remain unobstructed by directing air through designated inlet and outlet positions in each cavity, maintaining airflow speed despite high component density.
Solution Approach 2:
The middle cavity acts as an intermediary space between the first and second cavities. It houses the power supply and serves as a thermal buffer zone, preventing direct thermal interference between hard disk trays while maintaining overall space efficiency. The power supply's own fan further assists in managing airflow through this intermediary region.
3Volume of moving object
If power supply is placed in the middle of the chassis, then space utilization is improved, but airflow obstruction and heat accumulation may occur
Solution Approach 1:
The middle cavity is specifically designed as a dedicated space for the power supply, with its own airflow management characteristics. Air inlets and outlets are positioned to ensure that the power supply region has adequate airflow independent of the hard disk cavities, preventing heat accumulation despite the compact central placement.
Solution Approach 2:
The power supply is equipped with its own fan that can independently manage its thermal environment. This self-service cooling capability allows the power supply to dissipate heat effectively from its central location without interfering with or being interfered by airflow in the hard disk cavities, resolving the heat accumulation issue while maintaining space efficiency.
