Server Rack Airflow Valves for Per-Server Cooling Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server rack systems are inefficient in directing airflow for heat dissipation, as they lack adaptive control mechanisms to adjust airflow based on individual server cooling needs, leading to suboptimal temperature management and increased energy consumption.
Innovation Solution
A server rack system with hollow tubular support posts and cartridges that include valve members to control airflow, allowing for adjustable airflow through electromechanical or manual control, with a local or central controller managing airflow based on temperature readings to optimize cooling for each server unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed airflow paths are used in server racks, then structural simplicity is maintained, but adaptability to different cooling needs is reduced
Solution Approach 1:
The airflow control system is segmented into multiple independent cartridges, each with its own valve member, allowing individual control of airflow to different server units. This segmentation enables adaptive cooling without requiring a completely complex centralized system, as each cartridge operates independently based on local temperature conditions.
Solution Approach 2:
The system transitions from static fixed airflow paths to dynamic adjustable airflow paths using valve members that can open and close based on thermal conditions. The controller dynamically adjusts the state of each cartridge's valve member to optimize cooling efficiency while maintaining structural simplicity through standardized cartridge components.
2Reliability
If uniform airflow is provided to all servers, then system simplicity is maintained, but cooling efficiency for individual servers deteriorates
Solution Approach 1:
Each cartridge is designed with local quality control through individual valve members that can be independently actuated based on the specific thermal needs of each server unit. This allows the system to provide customized airflow to each location rather than uniform airflow, improving temperature management effectiveness while reducing energy waste on already-cooled units.
Solution Approach 2:
The system incorporates temperature sensing feedback through thermometers or temperature sensors that monitor thermal conditions at each server location. This feedback information is used by the controller to adjust the valve member positions in real-time, ensuring optimal cooling efficiency and preventing energy waste by only activating cooling when and where it is needed.
3Adaptability or versatility
If airflow control valves are added to each cartridge, then adaptive cooling is achieved, but manufacturing complexity increases
Solution Approach 1:
The system segments the airflow control functionality into standardized, modular cartridges that can be manufactured independently using standardized processes. Each cartridge contains a valve member and sealing components designed as repeatable units, simplifying manufacturing through standardization while enabling individual control of airflow to different server positions.
Solution Approach 2:
The cartridge design incorporates universal, multi-functional components including valve members that can be manually or electromechanically actuated, sealing elements that accommodate various server configurations, and standardized mounting interfaces. This universality allows the same cartridge design to serve multiple functions and positions, reducing manufacturing complexity despite the added adaptability features.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively manages airflow to meet the specific cooling needs of each server, enhancing heat dissipation efficiency, reducing energy consumption, and allowing for modular and upgradable solutions without significant facility modifications.
Implementation Method 1
cartridges that include valve members to control airflow, allowing for adjustable airflow through electromechanical or manual control
Implementation Method 2
air conditioned air is introduced to forward side panels through passages provided on the upper and lower surfaces
Implementation Method 3
Air travels through the server from the front section of the server to a rear section and then exits through a passage in the lateral sidewall to a cartridge that is provided in a rear panel. Next the air is returned to the air conditioner unit for recirculation.

AI summary
Disclosed is system, method, and rack stand portion for the advantageous cooling of computer equipment 305. The rack stand 200 includes a hollow body 210, 212 that may be formed of cartridges 2416. Gas from an airflow source 5204 is guided into the rack stand body and then into a sealed case of the computer equipment. Air flow is then guided out of the computer equipment for recirculation, exhaust, or other purpose.
