Cold Row Enclosure Cooling Without Raised Floor Plenums
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers face significant energy consumption and inefficiencies in cooling systems due to high power usage by servers and HVAC systems, leading to increased operational costs and heat management challenges in densely populated server racks.
Innovation Solution
The implementation of a cold row encapsulation structure with integrated cooling modules that utilize water-based cooling coils to exchange heat with hot air, eliminating the need for raised floors and underfloor plenums, and allowing for efficient air circulation and cooling without introducing outside air, while also optionally mixing outside cool air when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional HVAC systems are used to cool data centers, then cooling coverage is provided, but energy consumption increases significantly
Solution Approach 1:
The data center cooling system is segmented into individual rack-level cooling units rather than using centralized HVAC. Each cooling unit serves a specific rack, allowing for localized cooling control and elimination of energy-wasting airflow to unoccupied spaces.
Solution Approach 2:
Cooling is applied locally at each rack level rather than uniformly throughout the entire data center space. This allows cooling resources to be concentrated where heat is generated, improving cooling efficiency while reducing overall energy consumption.
2Ease of operation
If raised floors and underfloor plenums are used for air distribution, then cooling air can be supplied to cold aisles, but device complexity and construction cost increase
Solution Approach 1:
The complex raised floor and underfloor plenum infrastructure is completely removed from the system. Instead, cooling air is distributed directly through the rack-mounted cooling units, eliminating the need for elaborate floor structures while maintaining effective air distribution.
3Temperature
If cold rows are enclosed to improve cooling efficiency, then cooling effectiveness increases, but air flow management becomes more complex
Solution Approach 1:
The cold row enclosure and cooling units are merged into an integrated rack-level system. The enclosure naturally directs airflow through the servers, and the cooling units are positioned to work in conjunction with the enclosure structure, simplifying air flow management while maintaining high cooling effectiveness.

AI summary
An apparatus includes an enclosure defining an interior space and includes a server-rack port configured to engage one or more of racks such that one or more servers installed in each rack are contiguous to the interior space. The enclosure is inside of a room and each server includes a fan that draws air from the interior space into the server and expels the air outside of the enclosure into the room. The apparatus also includes a mixing chamber that is contiguous to the enclosure. The mixing chamber includes a set of one or more dampers that are contiguous to natural air outside of the room and that are opened up when a temperature outside reaches a threshold value.
