Electronic Device Vent Lattice Cylindrical Protrusions Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with vent holes experience increased pressure loss of airflow due to inclined louvers, which compromise the blind effect and airflow efficiency.
Innovation Solution
The electronic device incorporates a housing with a lattice unit featuring cylindrical protrusions along the vent direction of the vent holes, reducing pressure loss while maintaining the blind effect by hiding the internal components and airflow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If inclined louvers are provided within the vent hole opening to achieve blind effect, then the blind effect is improved, but the pressure loss of airflow increases
Solution Approach 1:
The vent hole opening is segmented into multiple through holes arranged in a lattice pattern, with cylindrical protrusions at intersections. This segmentation allows airflow to pass through multiple smaller openings rather than being blocked by inclined louvers, reducing pressure loss while maintaining the blind effect through the lattice structure.
Solution Approach 2:
Cylindrical protrusions are provided at the intersections of lattice lines in the vent hole opening. These curved cylindrical elements reduce airflow resistance compared to sharp-edged louvers, allowing smoother airflow while maintaining the blind effect through their geometric arrangement.
2Shape
If inclined louvers are provided to hide internal components, then the aesthetic appearance is improved, but the cooling efficiency decreases due to increased pressure loss
Solution Approach 1:
The vent hole is divided into multiple through holes forming a lattice pattern with cylindrical protrusions at intersections. This segmented structure provides adequate airflow paths for cooling while the lattice arrangement maintains aesthetic appearance by hiding internal components effectively.
Solution Approach 2:
The lattice unit with multiple through holes and cylindrical protrusions creates a porous-like structure that allows airflow to pass through while maintaining visual privacy. The porous arrangement provides multiple flow paths that reduce pressure loss compared to solid inclined louvers.
