Docking Plenum for Server Rack Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers face challenges in efficiently evacuating heat generated by multiple server computers, leading to high cooling costs and potential performance degradation due to the configuration of racks in a back-to-back setup, which creates a cool aisle and a hot aisle between them.
Innovation Solution
A docking plenum with a pair of sides coupled to top panels, featuring a front and rear opening for racks, forms a heated air cavity that directs heated air through a top aperture, utilizing fans to draw cooled air from outside and exhaust heated air through the plenum's top, while engagement divots on the floor secure the racks in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If racks are placed in a back-to-back configuration to house multiple server systems, then the data center can efficiently organize and access computer systems, but heat accumulates in the hot aisle between racks leading to high cooling costs and potential performance degradation
Solution Approach 1:
The enclosure is segmented into multiple compartments by partition walls, with each compartment receiving cooling air from a separate source. This divides the hot aisle into isolated sections, preventing heat accumulation and allowing independent cooling of each rack compartment while maintaining organized rack placement.
2Stability of the object's composition
If racks are secured in a stationary location within the enclosure, then rack stability and organization are improved, but the structure becomes more complex requiring additional docking mechanisms
Solution Approach 1:
The docking mechanism merges the rack frame with the enclosure structure by providing engagement features that connect directly to the enclosure walls and floor. This integration secures racks in stationary positions while using the enclosure's own structural elements as docking points, avoiding additional complex external docking mechanisms.
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 docking plenum effectively manages heat by creating a pathway for heated air to exit, reducing cooling costs and maintaining system performance by isolating hot air between racks and directing it away from the data room.
Implementation Method 1
the fans draw air from outside the plenum across the interior of the computer systems. Heated air exits the computer systems and enters the heated air cavity
Data Source
AI summary
A docking plenum for a rack is disclosed. The docking plenum includes a pair of sides that are coupled to first and second panels at the top of the docking plenum. The panels at the top of the docking plenum are separated from one another by an aperture. The docking plenum includes a front opening and a rear opening between the two sides. Each of the front opening and the rear opening are sized to receive a rack. The placement of a first rack in the front opening and a second rack in the rear opening creates a heated air cavity that is formed by the racks, the floor of the docking plenum, and the panels at the top of the docking plenum. When the racks are placed in the opening, and when one or more fans in the computer systems are activated, the fans draw air from outside the plenum across the interior of the computer systems. Heated air exits the computer systems and enters the heated air cavity. The heated air exits the heated air cavity through the aperture in the top of the docking plenum. Each rack may include wheels.
