Adjustable Inlet Duct for Side Air Intake Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network cabinet designs face challenges in accommodating electronic equipment with varying air flow requirements, particularly when equipment has side intakes and exhausts, as they often segregate 'cold' and 'hot' air incorrectly, leading to overheating issues.
Innovation Solution
An adjustable inlet duct system featuring a duct body, internal baffle, side ducts, and baffles that can be configured to direct 'cold' air to side intakes while preventing 'hot' exhaust air from mixing with 'cold' air, using removable components like side ducts and baffles to accommodate different equipment configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional front-to-back segregated cabinet design is used, then cooling air separation is simplified, but equipment with side air intakes cannot be properly accommodated and may intake hot exhaust air
Solution Approach 1:
The cabinet interior is segmented into multiple zones using adjustable baffles and ducts. Cold air intake zones and hot air exhaust zones are physically separated, allowing equipment with side air intakes to receive only cold air while exhaust air is directed to designated hot zones. This segmentation enables proper airflow management for various equipment configurations without mixing cold and hot air streams.
Solution Approach 2:
The cabinet cooling system uses adjustable and removable baffles and ducts that can be dynamically reconfigured based on equipment placement and airflow requirements. This dynamic adaptability allows the same cabinet to properly accommodate different equipment types (front-to-back, side-intake, side-exhaust configurations) while maintaining reliable separation of cold and hot air zones for each configuration.
2Reliability
If custom venting is designed for each equipment type, then specific cooling requirements are met, but system complexity and installation difficulty increase
Solution Approach 1:
The cabinet employs a universal cooling system with standardized adjustable baffles and removable ducts that can be configured to meet various equipment cooling requirements. Instead of designing custom venting for each equipment type, the same modular components can be arranged differently to accommodate front-to-back, side-intake, side-exhaust, and other airflow configurations, reducing system complexity while maintaining reliable cooling performance.
Solution Approach 2:
The venting system uses dynamic, adjustable components rather than fixed custom designs. Baffles can be repositioned and ducts reconfigured based on equipment placement, allowing a single universal system to adapt to different cooling requirements without increasing overall system complexity or installation difficulty.
3Volume of moving object
If equipment sizes vary, then cabinet space utilization improves, but duct system must accommodate different dimensions requiring adjustability
Solution Approach 1:
The duct system incorporates adjustable and removable components that can be dynamically reconfigured to accommodate equipment of varying dimensions. This dynamic adaptability allows optimal cabinet space utilization while ensuring proper airflow delivery to equipment regardless of size differences, as the ducts and baffles can be positioned to match specific equipment footprints.
Solution Approach 2:
A universal duct system design with standardized adjustable components serves multiple equipment size requirements. The same duct components can be configured for different equipment dimensions, eliminating the need for size-specific custom ductwork while maintaining proper airflow delivery and cabinet space efficiency.
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 system effectively directs cooling air to side intakes and separates it from exhaust air, preventing overheating and ensuring proper airflow for various electronic equipment configurations, enhancing cooling efficiency and preventing equipment shutdowns.
Implementation Method 1
The internal baffle partitions the internal cavity into a front portion and a rear portion and inhibits the flow of air between the front portion and the rear portion of the internal cavity
Implementation Method 2
The first side baffle extends between the top wall and the bottom wall of the first side duct and between the side wall of the first side duct and the side wall of the duct body to partition the air flow chamber into a front portion and a rear portion and inhibit the flow of air between the front portion and the rear portion of the air flow chamber

AI summary
An inlet duct system includes a duct body having a bottom wall and two side walls having at least one opening. An adjustable internal baffle is secured to the duct body such that the internal baffle can be positioned in multiple locations within an internal cavity defined by the duct body, inhibiting the flow of air between a front portion and a rear portion of the internal cavity. A first side duct is removably attached to the duct body and forms an air flow chamber that receives a fluid from an opening in one of the side walls and delivers the fluid above the duct body. A first side baffle is positioned within the air flow chamber, adjacent the internal baffle, inhibiting the flow of air between a front portion and a rear portion of the air flow chamber.
