Server Expansion Frame Cable Management and Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In servers with densely configured electronic components, there is a challenge in balancing the requirements for heat dissipation and cable management within limited space, leading to inefficiencies in both ventilation and cable organization.
Innovation Solution
The expansion frame and server design incorporate a main body with a storage space, a cable gathering component with a cable management space, two mount cages, a cable organizer, four circuit boards, and four connection cables. This configuration simplifies cable wiring, organizes cables effectively in a limited space, and provides sufficient space for heat dissipation and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If electronic components are densely configured in servers, then the number of functional modules supported increases, but the space for cable management becomes insufficient
Solution Approach 1:
The expansion frame is divided into multiple mount cages (first mount cage, second mount cage, third mount cage) that are assembled together, creating separate zones for different components. This segmentation allows cables from different component groups to be organized in distinct spaces, improving cable management efficiency while supporting multiple functional modules
Solution Approach 2:
A cable guide component is introduced as an intermediary element between the mount cages and the rear panel. This cable guide includes a first guide portion and a second guide portion that direct cables from different mount cages to their respective destinations, effectively managing cable routing in the limited space
2Quantity of substance
If electronic components are densely configured in servers, then the functional capacity increases, but heat dissipation becomes difficult
Solution Approach 1:
The expansion frame divides densely configured electronic components into separate mount cages with gaps between them. This spatial segmentation creates ventilation channels that allow air flow between component groups, improving heat dissipation while maintaining high functional capacity
Solution Approach 2:
The design utilizes three-dimensional space arrangement where mount cages are positioned at different locations (first, second, third mount cages) with vertical and horizontal spacing. This dimensional arrangement creates multiple ventilation paths and heat dissipation zones throughout the expansion frame structure
3Adaptability or versatility
If more expansion cards are installed in limited space, then the functional versatility increases, but cable organization becomes complex
Solution Approach 1:
The expansion frame segments multiple expansion cards into different mount cages, with each cage containing a subset of cards. This segmentation reduces the number of cables that need to be managed in any single location, simplifying overall cable organization while supporting diverse functional cards
Solution Approach 2:
The cable guide component serves as a mediator that automatically directs cables from specific mount cages to specific exit points on the rear panel. This intermediary structure simplifies cable organization by providing predetermined routing paths, reducing the complexity of managing cables for multiple expansion cards

AI summary
An expansion frame includes a main body, a cable gathering component fixed to the main body and having a cable management space, two mount cages, a cable organizer including a mount part and a cable organization part connected to each other, four circuit boards, and four connection cables. The mount cages are located on a side of the cable gathering component. The mount part is located between the mount cages. The cable organization part extends from the mount part towards the cable gathering component and has a cable gathering hole connected to the cable management space. Two of the circuit boards are disposed on one of the mount cages, and other two of the circuit boards are disposed on the other of the mount cages. The connection cables are connected to the circuit boards, disposed through the cable gathering hole and extend into the cable management space.
