Electronic Apparatus Chassis Venting for Hidden Fan Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses face a trade-off between appearance quality and cooling performance due to the presence of intake ports in the bottom surface, which can be unsightly and reduce air volume when eliminated.
Innovation Solution
The design incorporates a projecting part with vertical walls and vents on the chassis bottom surface to house fan suction ports, allowing air intake without visible openings, while maintaining efficient cooling through optimized fan placement and increased air volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an intake port with slit-shaped openings is arranged in the bottom surface of the chassis, then the fan can draw in outside air for cooling, but the intake port becomes noticeable and deteriorates the appearance quality
Solution Approach 1:
The intake port is moved from the bottom surface (2D plane) to the side surface of the chassis, changing its spatial dimension and location. This allows the bottom surface to maintain a clean, uninterrupted appearance while the fan continues to draw air through the side-mounted intake port, resolving the conflict between cooling performance and appearance quality.
Solution Approach 2:
The intake port function is extracted from the bottom surface and relocated to the side surface of the chassis. This separation allows the bottom surface to serve purely aesthetic purposes while the side surface handles the functional air intake requirement, eliminating the visual impact of slits on the bottom surface.
2Shape
If the intake port in the bottom surface is eliminated to improve appearance quality, then the design is improved, but the intake efficiency and air volume of the fans are reduced, resulting in deteriorated cooling performance
Solution Approach 1:
The air intake function is relocated from the bottom surface to the side surface of the chassis, utilizing a different spatial dimension. This maintains the aesthetic integrity of the bottom surface while preserving cooling performance through the side-mounted intake port that provides sufficient air volume to the fan.
Solution Approach 2:
The side surface of the chassis serves dual purposes: maintaining structural integrity and providing the air intake function through the positioned intake port. This multi-functional design eliminates the need for bottom surface slits while ensuring adequate cooling air supply.
