Airflow Panel Layout for Side-Breathing Equipment Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional enclosures for electronic equipment face challenges in thermal management, particularly with side breathing equipment, where recirculation and bypass issues lead to inefficient heat removal and increased operating temperatures, due to the concentration of thermal energy and vortex formation.
Innovation Solution
An air directing device with vertically arranged panels of differing widths is introduced to redirect airflow within the enclosure, minimizing recirculation by deflecting cooling air orthogonally into side breathing equipment while allowing a portion to pass by, thereby optimizing airflow and heat removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional enclosures are used for side breathing equipment, then the enclosure structure is simple, but recirculation and bypass issues cause inefficient heat removal and increased operating temperatures
Solution Approach 1:
The enclosure is segmented into distinct thermal zones using partitions and airflow directing elements. These segments create separate pathways for intake air and exhaust air, preventing recirculation while maintaining a relatively simple overall enclosure structure. The segmentation allows independent optimization of airflow paths without requiring complete structural redesign.
Solution Approach 2:
Airflow directing elements and partitions serve as intermediary components that channel and redirect airflow within the enclosure. These intermediaries guide cooling air to the required locations and direct hot exhaust air away from intake areas, resolving recirculation and bypass issues without adding complex active control systems.
2Productivity
If multiple enclosures are placed in a single data center room, then space utilization is maximized, but thermal management becomes more difficult and recirculation problems worsen
Solution Approach 1:
The harmful recirculation and bypass airflow paths are extracted and eliminated from the enclosure design. By removing these problematic airflow patterns through strategic positioning of airflow directing elements, the enclosure can coexist with other enclosures in a data center without contributing to collective overheating, thus enabling higher space utilization.
Solution Approach 2:
The enclosure incorporates localized thermal management features tailored to specific zones. Different regions of the enclosure have customized airflow paths and thermal characteristics, allowing each local area to be optimized for its specific thermal load while contributing to overall efficient thermal management in the data center environment.
3Productivity
If cooling air is directed directly into side breathing equipment, then heat removal efficiency is improved, but recirculation and bypass problems reduce the effectiveness of the cooling air
Solution Approach 1:
Airflow directing elements are positioned in advance to pre-channel cooling air along optimal pathways before it reaches the equipment. This preliminary direction of airflow ensures that cooling air is already positioned correctly to enter the equipment efficiently, while simultaneously directing exhaust air away to prevent recirculation, thereby maximizing heat removal efficiency and minimizing energy loss.
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
The air directing device significantly reduces recirculation and temperature hotspots within the enclosure, enhancing cooling efficiency and maintaining uniform temperatures, thus improving the thermal management of side breathing equipment.
Implementation Method 1
Internal fans may draw or push air through the housing from front-to-rear or from side-to-side over the heated internal elements within the housing. The air absorbs the thermal energy from the internal elements and carries it away as it exits the housing.
Implementation Method 2
The air absorbs the thermal energy from the internal elements and carries it away as it exits the housing.

AI summary
An air directing device for thermal management in side breathing equipment includes at least three vertical panels disposed in generally parallel relationship and horizontally spaced a fixed distance from one another. Each panel defines a fin arranged orthogonally relative to an airflow path for deflection of cooling air into side breathing equipment. At least one of the panels is an inner panel that is wider than two outer panels. The air directing device further includes at least one connection member connecting the outer panels to one another.
