Rotatable Server Fan Module for Faster Chassis Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed fan support in server modules complicates assembly and disassembly processes, leading to inefficient maintenance and assembly of fan modules in server systems.
Innovation Solution
A server chassis design with a rotatable fan module driven by a driving member, allowing the fan module to move in and out of the bottom case perpendicular to the bottom plate, facilitated by a driving member comprising side arms and a middle handle, with a transmission mechanism using an incomplete gear and rack for smooth assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fan support is fixed in the fan module, then the structural stability is improved, but the assembly and disassembly process becomes complex and inefficient
Solution Approach 1:
The fan support is changed from a fixed structure to a rotatable structure that can dynamically change its position. The driving member (handwheel with gear mechanism) enables the fan support to rotate between a working position (where it supports the fan module) and a removed position (where it can be detached), allowing the same structure to serve both stability and ease of assembly/disassembly requirements
2Reliability
If the fan module is fixed in the bottom case, then the reliability of operation is improved, but the maintenance and assembly process becomes complex
Solution Approach 1:
The fan module is designed as a separable component that can be independently assembled and disassembled from the bottom case. The fan support acts as an intermediary that can be removed, allowing the fan module to be detached as a complete unit rather than requiring disassembly of individual components, thus reducing assembly process complexity while maintaining operational reliability
3Reliability
If the entire fan module is assembled and disassembled together, then the heat dissipation performance is maintained, but the assembly and disassembly time increases
Solution Approach 1:
The rotatable fan support with driving member enables rapid transformation between assembled and disassembled states. By rotating the handwheel to move the fan support between working and removed positions, the entire fan module can be quickly assembled or disassembled as a unit without compromising its internal heat dissipation structure, significantly reducing maintenance time

Function Achieved in This Case
Enables labor-saving and efficient assembly and disassembly of fan modules, improving maintenance efficiency and reducing assembly complexity by allowing seamless connection and disconnection of fan modules to the server mainboard.
Implementation Method 1
The driving member is rotatably connected to the fan support, and the driving member is adapted to drive the fan module to move relative to the bottom case in a direction perpendicular to the bottom plate

AI summary
Disclosed are a server chassis and a server. The server chassis includes a bottom case and a fan module. The bottom case includes a bottom plate, and the fan module is arranged in the bottom case. The fan module includes a fan support, multiple fan bodies, and a driving member. The fan support is provided with multiple accommodating cavities, and the multiple fan bodies are mounted in the multiple accommodating cavities. The driving member is rotatably connected to the fan support, and the driving member is adapted to drive the fan module to move relative to the bottom case in a direction perpendicular to the bottom plate. The fan module moves in and out of the bottom case through the driving member. The server includes the server chassis.
