Rack Mounting Air Flap for Data Center Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers face challenges in efficiently managing waste heat and rapidly scaling computing capacity due to recirculation of exhaust air, which reduces heat removal efficiency and requires extensive resources for infrastructure changes.
Innovation Solution
A modular data center system with air flap structures that restrict airflow through mounting portions when servers are not installed, preventing recirculation of exhaust air and facilitating efficient cooling, while also enabling quick installation and removal of servers through shelving modules and backplane assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If exhaust air is allowed to recirculate back to the inlet end of the rack, then the feedback loop may establish, but heat removal capacity is reduced and waste heat buildup occurs
Solution Approach 1:
The rack is divided into multiple mounting portions with individual air flap structures for each portion. Each air flap can be independently controlled to segment the airflow paths, preventing exhaust air from recirculating to inlet portions while maintaining cooling efficiency for each server compartment.
Solution Approach 2:
Air flap structures act as intermediary elements between the exhaust air flow and inlet air flow. These flaps selectively block or allow airflow based on server presence, serving as a mediator that prevents harmful recirculation while permitting necessary cooling airflow when servers are installed.
2Productivity
If extensive cabling and connections are installed for each server, then computing capacity increases, but installation time and resource expenditure increase significantly
Solution Approach 1:
Multiple cabling connections (power, data, control) are merged into a single integrated backplane assembly. The backplane provides standardized connection points that automatically align with server interfaces, combining what would otherwise be separate installation tasks into one unified connection process.
Solution Approach 2:
The backplane assembly serves multiple functions simultaneously: it provides power connections, data networking connections, and control signal connections through a single universal interface. This multi-functional design eliminates the need for separate specialized connections for each type of service.
3Productivity
If rack infrastructure is designed and built to accommodate servers, then computing capacity is established, but substantial time and resources are required for design, cable laying, and installation
Solution Approach 1:
The backplane assemblies and air flap structures are pre-installed and configured in the rack mounting portions before servers are deployed. Connection interfaces and airflow control mechanisms are prepared in advance, so that when servers are installed, they automatically interface with pre-configured connections without requiring additional setup work.
Solution Approach 2:
The rack infrastructure is segmented into independent mounting portions, each with its own backplane assembly and air flap control. This modular segmentation allows individual portions to be configured and tested independently, and servers can be deployed to specific portions without affecting other areas of the rack.
4Reliability
If servers are mounted in racks with fixed connections, then computing operations can proceed, but installing and uninstalling servers becomes time-consuming
Solution Approach 1:
The air flap structures are designed to be dynamic rather than fixed, automatically adjusting their position based on server presence. When a server is installed, the flap retracts to allow airflow; when removed, the flap returns to block the opening. This dynamic behavior maintains connection stability during operation while enabling easy server installation and removal.

Implementation Method 1
An air flap structure configurable to restrict airflow through an internal space of the mounting portion
Implementation Method 2
directing cooling air into an intake side of a rack in which computer systems are installed, through an interior of the rack so that the cooling air removes heat from heat-producing components

AI summary
One or more racks in a rack computing system include shelving systems with mounting portions to receive computer systems in the mounting portion. The mounting portion can include an air flap structure that can restrict airflow through internal space of the mounting portion when a rack computer system is absent from the mounting portion. The air flap structure can retract to enable a computer system to be mounted in an internal space of the mounting portion. A mounting portion can include at least a portion of a backplane assembly that can be aligned to couple with a rack computer system mounted in the mounting portion to communicatively couple the rack computer system with one or more communication networks. The mounting portion can include an ejection mechanism that can eject an installed computer system from the mounting portion.
