Cooling system and cooling method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In air-conditioning environments with aisle capping, high-heat-generating housings disrupt airflow, causing other heat-generating housings to experience reduced cooling efficiency and temperature rises due to mixed intake/exhaust circulation, leading to hot spots and increased power consumption.
Innovation Solution
A cooling system that separates airflow between high-heat-generating and other housings using a duct and cooling enhancement means, such as a heat exchanger, to isolate and enhance cooling performance specifically for the high-heat-generating housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If aisle capping is implemented to separate intake and exhaust airflows, then cooling efficiency is improved, but high-heat-generating housings disrupt the separated airflow causing hot spots in adjacent housings
Solution Approach 1:
The patent divides the airflow management into two levels: global aisle-level segmentation (intake aisle vs. exhaust aisle) and local housing-level segmentation (individual ducts for high-heat-generating housings). This dual segmentation prevents hot airflow from high-heat housings from contaminating the intake airflow for adjacent housings, while maintaining the overall aisle capping structure.
Solution Approach 2:
The patent applies different airflow management strategies to different locations: standard aisle capping for most housings, and enhanced local ducting specifically for high-heat-generating housings. This local quality approach targets the problematic areas (high-heat housings) with additional airflow control measures while leaving other areas with simpler aisle capping.
2Temperature
If ducts are added to isolate high-heat-generating housings, then airflow separation is improved, but system complexity increases
Solution Approach 1:
The patent makes the duct configuration dynamic and adaptive: ducts are installed only for high-heat-generating housings rather than all housings uniformly. This dynamic approach allows the system to add complexity only where needed (at high-heat locations) while keeping the rest of the system simple with standard aisle capping.
Solution Approach 2:
The patent applies complex ducted airflow management locally at high-heat-generating housings while maintaining simple aisle capping elsewhere. This local quality principle ensures that the increased complexity is confined to specific problem areas rather than being distributed throughout the entire system.
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
Effectively prevents hot spots by isolating airflow and enhancing cooling for high-heat-generating housings, reducing the impact on adjacent devices and optimizing energy use.
Implementation Method 1
the cooling enhancement means is a heat exchanger for performing heat exchange between the first airflow and a coolant or water
Implementation Method 2
the cooling enhancement means is an air blower which supports circulation of the first airflow inside the duct

AI summary
When an enclosed space is formed, by at least one of surfaces forming an exterior shape of a shielding member and an intake or exhaust surface among surfaces forming an exterior shape of heat-generating housings, in such a way that a taken-in airflow and an exhausted airflow of the heat-generating housings installed in at least two rows can be separated or substantially separated, a cooling system includes: a duct formed to be able to separate or substantially separate a first airflow and a second airflow being intake/exhaust of a specific heat-generating housing among the heat-generating housings, and heat-generating housings other than the specific heat-generating housing, respectively; and a cooling enhancement unit enhancing cooling for the specific heat-generating housing by acting on the first airflow, thereby avoiding occurrence of a hot spot due to a high-heat-generating housing, in a system building an air-conditioning environment such as aisle capping.
