Electronic Apparatus Chassis Venting for Cooling Without Visible Intakes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses face a trade-off between appearance quality and cooling performance, as eliminating intake ports in the bottom surface to improve design reduces intake efficiency and air volume, leading to deteriorated cooling.
Innovation Solution
The electronic apparatus incorporates a chassis with a projecting part that protrudes from the bottom surface and has a vertical wall with vents, where fan suction surfaces face an inner space, allowing air intake through these vents without visible openings, and includes exhaust ports in the rear edge for efficient air discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an intake port with slit-shaped openings is arranged in the bottom surface of the chassis, then the cooling performance is improved, but the appearance quality deteriorates due to noticeable openings
Solution Approach 1:
The intake port is repositioned from the bottom surface (2D plane) to the rear edge (vertical dimension), allowing the bottom surface to remain smooth and aesthetically pleasing while maintaining effective air intake through the rear exhaust ports
2Shape
If the intake port in the bottom surface is eliminated to improve design, then the appearance quality is improved, but the intake efficiency and air volume are reduced, resulting in deteriorated cooling performance
Solution Approach 1:
The air intake function is shifted from the bottom surface to the rear edge of the chassis, utilizing the vertical space and rear exhaust ports to maintain cooling efficiency while achieving a smooth, aesthetically pleasing bottom surface
Solution Approach 2:
The rear exhaust ports serve as intermediary structures that facilitate air intake and discharge functions, allowing the bottom surface to remain closed and aesthetically pleasing while maintaining effective thermal management through the rear of the device
