Solution Overview

Problem

Existing data center cooling systems face inefficiencies in heat removal due to server racks being back-to-back, requiring excessive fan effort to push hot air, and lack of redundancy in cooling capacity.

Innovation Solution

A chamber is provided to mix, channel, and diffuse heated air from server racks to a heat removal cabinet, with configurable diffusion angles and redundant cooling capacity through additional cabinets, using refrigerants with low ozone depletion potential.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If server racks are placed back-to-back in a narrow space, then space utilization is improved, but fan workload increases excessively to push hot air

Engineering Contradiction:
Improvespace utilizationVSAvoidfan workload
Core Design Contradiction:
Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

A heat staging chamber is introduced as an intermediary component between the server racks and cooling systems. This chamber receives hot air from multiple racks, mixes and diffuses it, then channels it to heat removal cabinets. This intermediary structure eliminates the need for high fan pressure in narrow back-to-back configurations while maintaining effective heat removal.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If cooling capacity is increased to handle all heat, then temperature control is improved, but system complexity and cost increase

Engineering Contradiction:
Improvetemperature controlVSAvoidcooling system complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The heat removal system uses adjustable diffusers with configurable angles that can be manually or automatically adjusted. This dynamic adjustment capability allows the system to optimize airflow patterns and cooling capacity based on actual heat loads, providing temperature control without requiring a fixed high-capacity cooling system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cooling system is divided into modular heat removal cabinets that can be individually adjusted and configured. Each cabinet handles a specific zone or rack group, allowing incremental scaling and simplified maintenance compared to a monolithic cooling system.

Inventive Principle:
Principle #1Segmentation

3Reliability

If redundant cooling capacity is added, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecooling redundancyVSAvoidsystem configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The heat staging chamber and diffuser system serve multiple functions: they mix and diffuse hot air from various racks, channel it to appropriate heat removal cabinets, and provide configurable airflow patterns. This multi-functionality reduces the need for separate dedicated systems for each rack, simplifying the overall redundant configuration.

Inventive Principle:
Principle #6Universality (Multi-functionality)
