Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face challenges in thermal management, particularly in efficiently cooling internal componentry within restricted spaces like data racks, where conventional cooling methods may not adequately address high ambient temperatures and limited airflow.
Innovation Solution
A portable, modular cooling system powered via the Power-over-Ethernet (PoE) standard, which draws cooler ambient air and uses PoE-enabled Ethernet connections to supply electrical power to cooling fans, providing convective cooling and maintaining optimal temperatures while maintaining a clean rack environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cooling methods are used in data racks, then cooling capability is limited, but device complexity and installation requirements increase
Solution Approach 1:
The cooling device is powered by PoE technology, drawing electrical power directly from the network infrastructure through the Ethernet cable. This self-service approach eliminates the need for separate power wiring, outlets, or power supply units, allowing the device to cool network equipment while being powered by the same infrastructure it serves.
Solution Approach 2:
The patent combines the cooling function with the existing PoE-powered network infrastructure. By merging the cooling device into the network equipment ecosystem, it leverages available power and control channels, reducing installation complexity while enhancing cooling capability in restricted spaces.
2Reliability
If PoE-powered cooling system is deployed, then power redundancy and flexible installation are achieved, but power consumption requirements increase
Solution Approach 1:
The PoE-powered cooling device can draw power from any PoE-enabled network switch, making it universally compatible with standard network infrastructure. This multi-functionality allows the same PoE infrastructure to serve both networking and cooling purposes, providing power redundancy without requiring additional power consumption beyond what the network infrastructure already supplies.

Implementation Method 1
The cooling system draws cooler ambient air and uses PoE-enabled Ethernet connections to supply electrical power to cooling fans, providing convective cooling
Data Source
AI summary
A portable or modular cooling system is operated via the power-over-Ethernet (PoE) standard. The cooling system receives electrical power via an Ethernet connection to a source device (such as a server, switch, or other PoE-enabled equipment). The cooling system may thus be used to spot-inject cooler ambient air in the vicinity of the source device without the need for grid electric and for cumbersome electrical wiring.
