Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As IHS hardware components increase in speed and power consumption, the heat generated also increases, necessitating effective cooling to prevent overheating, instability, and damage, while existing cooling systems may not efficiently adapt to varying cooling needs.
Innovation Solution
A replaceable fan module with a centrifugal fan mounted on a printed circuit board, configured for PCIe form factor, which can be substituted for PCIe computing components, providing airflow cooling by drawing air from within the chassis and directing it orthogonally through openings in the bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling fan capacity is increased to handle higher heat generation from faster hardware components, then cooling effectiveness is improved, but device complexity and power consumption increase
Solution Approach 1:
The PCIe slot is designed to serve dual purposes: hosting computing components (GPUs, NICs, storage controllers) and hosting cooling fan modules. This allows the same physical infrastructure to provide both computational functionality and thermal management, reducing overall system complexity while maintaining effective cooling capacity for high-power components
Solution Approach 2:
The cooling system enables dynamic configuration where fan modules can be substituted for computing components based on real-time cooling requirements. The system can adapt its cooling capacity by inserting higher-capacity fan modules when heat generation increases, rather than being locked into a fixed cooling configuration
2Temperature
If fixed cooling systems are used to maintain stable thermal conditions, then temperature control is improved, but adaptability to varying cooling needs deteriorates
Solution Approach 1:
The system transitions from static cooling to dynamic cooling by allowing hot-swappable fan modules in PCIe slots. This enables the cooling configuration to be adjusted in real-time based on the computational load and heat generation of installed components, providing both temperature stability and adaptability
Solution Approach 2:
The cooling system allows changing of fan module parameters (size, airflow capacity, speed) by substituting different PCIe fan modules. This enables the system to match cooling capacity to the specific thermal requirements of different computing components without redesigning the entire cooling architecture
3Productivity
If PCIe slots are dedicated solely to computing components, then computational functionality is maximized, but cooling flexibility is reduced
Solution Approach 1:
PCIe slots are designed as universal interfaces that can accommodate both computing components and cooling fan modules. This multi-functionality allows the system to maximize computational functionality when needed while maintaining the flexibility to provide enhanced cooling by substituting fan modules into available PCIe slots

AI summary
A replaceable fan module may be swapped with computing components installed in PCIe slots of a chassis that may include one or more IHSs (Information Handling Systems), such as rack-mounted servers. The replaceable fan module may include a centrifugal fan that is mounted on a printed circuit board, where an exhaust of the centrifugal fan is oriented towards openings in a bracket used to fasten the printed circuit board within a PCIe slot of the chassis. The printed circuit board may include pins for electrically coupling the replaceable fan module to the PCIe slot of the chassis, where the pins are arranged according to a PCIe form factor and the replaceable fan module is activated and configured for operation upon coupling of the pins to a connector of the PCIe slot. One or more additional centrifugal fans may be added to the printed circuit board.
