Back-to-Back Shallow Rack Layout for Dense Data Center Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers face challenges with excessive heat generation from multiple computer systems, leading to high cooling costs and reduced capacity due to the large footprint required for alternating hot and cool aisles in traditional rack arrangements.
Innovation Solution
A rack system with a shallow configuration is placed in a back-to-back arrangement, with user-accessible components facing forward and heated air expelled between the racks, coupled with a tension bar to prevent tipping and optimize space usage, resulting in a narrower hot aisle and reduced overall footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If racks are arranged in alternating hot and cool aisles to manage heat, then heat management is improved, but the footprint and floor space consumption increase
Solution Approach 1:
The patent transitions from a traditional horizontal aisle arrangement to a vertical rack placement configuration. Racks are positioned upright with fronts facing each other, creating vertical hot aisles between racks rather than horizontal cool/cold aisles. This dimensional change allows heat to be expelled vertically between racks, reducing the horizontal footprint while maintaining effective heat management.
Solution Approach 2:
The patent inverts the traditional rack arrangement by placing racks vertically with fronts facing each other rather than horizontally with backs facing each other. This inversion creates narrow vertical hot aisles between racks, allowing heat to be expelled upward between adjacent racks, thereby reducing the overall floor space required while maintaining effective thermal management.
2Area of stationary object
If racks are placed close together to reduce footprint, then space efficiency is improved, but heat dissipation becomes more difficult
Solution Approach 1:
The patent creates vertical heat dissipation pathways by positioning racks upright with narrow gaps between them. Heat is expelled vertically through these narrow gaps rather than horizontally, allowing racks to be placed closer together horizontally while maintaining effective heat dissipation through the vertical dimension.
Solution Approach 2:
The patent segments the heat dissipation pathway into multiple narrow vertical channels between adjacent racks. Each gap between racks acts as an independent heat dissipation channel, allowing heat to be efficiently expelled from multiple locations simultaneously, thereby maintaining effective cooling even when racks are densely packed.
3Quantity of substance
If racks have deep configurations to house long computer systems, then system capacity is improved, but the footprint and space utilization worsen
Solution Approach 1:
The patent reorients computer systems from horizontal to vertical placement within racks. By positioning systems vertically with their fronts facing the narrow gap between racks, the design accommodates long systems along the vertical dimension rather than requiring extensive horizontal depth, thereby maintaining system capacity while reducing footprint.
Solution Approach 2:
The patent inverts the traditional horizontal rack configuration by placing racks vertically and positioning computer systems upright within them. This inversion allows systems to be arranged along the vertical axis, enabling long systems to be housed without increasing the horizontal footprint, thus maintaining system capacity while optimizing space utilization.

AI summary
A rack system is disclosed. The racks and the computer systems included within the racks have a shallow configuration. The racks are placed next to one another in a back-to-back configuration in which the backs of each of the racks are adjacent to one another. All of the user-accessible components of the computers system face toward the front of each rack. The heated air from each of the computer systems is expelled in the space between each of the racks. The space between each of the racks is relatively narrow, as there are no user-accessible components between the racks. The racks are coupled to one another with a bar that may include at least some spring action to accommodate some movement of the racks toward or away from one another without the tipping of either rack.
