Problem
Existing server designs face challenges in maintainability and heat dissipation reliability due to the fixed placement of heat dissipation fans and server mainboards, requiring complete disassembly for maintenance and affecting online operation.
Innovation Solution
The server design includes a chassis with a backplane, a rear board, and fan modules that can be plugged and unplugged, allowing for online replacement of fans and mainboards, along with air ducting apparatuses to ensure effective heat dissipation of components, enabling maintenance without disrupting server operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat dissipation fan and server mainboard are fixed at the back of the server, then the heat dissipation function is ensured, but the maintainability deteriorates as the entire server must be disassembled for replacement
Solution Approach 1:
The server back panel is segmented into independently replaceable modules: the heat dissipation fan module and the server mainboard module. Each module can be removed and replaced separately without affecting the other, eliminating the need to disassemble the entire server for maintenance while preserving the fixed-position heat dissipation architecture.
2Temperature
If the heat dissipation fan is disposed in the middle of the server, then heat dissipation of hard disk and chip is achieved, but device complexity increases and maintainability decreases
Solution Approach 1:
The heat dissipation system is segmented into modular components with dedicated air ducts for different heat sources. The hard disk heat dissipation path and chip heat dissipation path are separated into distinct modules, simplifying the overall structure while maintaining effective heat dissipation for each component.

Function Achieved in This Case
This design enhances server maintainability and heat dissipation reliability by allowing for online replacement of components, reducing downtime and improving overall system reliability while maintaining effective heat management.
Implementation Method 1
through rotation of the fan and cooperation between the second air ducting apparatus and the first air ducting apparatus, air that enters from the front of the backplane through the ventilation opening on the backplane turns towards the rear board and then flows out of the chassis after passing through the fan module, so as to dissipate heat of a component on the rear board
