Electronic Apparatus Vent Louver Design for Concealment and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic apparatus designs that use louvers for exhaust ports to prevent component exposure face a trade-off between ventilation efficiency and component concealment, where reducing the louver interval improves ventilation but compromises concealment, and increasing the interval worsens ventilation.
Innovation Solution
The design incorporates a vent with first louvers oriented vertically and second louvers positioned between the components and first louvers, where a straight line between adjacent first louvers intersects the second louvers, allowing for increased louver intervals while maintaining concealment and enhancing ventilation efficiency.

Engineering Contradiction Analysis
1Reliability
If the interval between adjacent louvers is set short to prevent component exposure, then component concealment is improved, but ventilation efficiency deteriorates
Solution Approach 1:
The exhaust port is segmented into two sets of louvers: first louvers (outer) and second louvers (inner). The first louvers are spaced apart to provide large ventilation areas, while the second louvers are positioned between the component and first louvers to block component exposure. This segmentation allows each louver set to perform its specific function optimally without compromising the other.
Solution Approach 2:
The solution transitions from a single-layer louver structure to a multi-layer louver structure by adding second louvers in the depth dimension between the component and first louvers. This dimensional change enables the system to simultaneously achieve component concealment (through the second louvers blocking line-of-sight) and ventilation efficiency (through the widely spaced first louvers).

Disclosed herein is an electronic apparatus including a component disposed inside the electronic apparatus, a vent that is located in a first direction with respect to the component disposed inside the electronic apparatus and is opened toward the external of the electronic apparatus, a plurality of first louvers that are provided in the vent and are lined in a second direction perpendicular to the first direction when the vent is viewed along the first direction, and a plurality of second louvers that are located between the component disposed inside the electronic apparatus and the plurality of first louvers and are lined in the second direction when the vent is viewed along the first direction. A straight line that passes between adjacent two first louvers and is along the first direction intersects any of the plurality of second louvers.
