Fan Frame Waved Structure for Airflow Enhancement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan frames with flat wind enter and exhaust sides limit wind rate and wind current, resulting in reduced heat dissipation effectiveness in electronic products, as they restrict airflow and hinder the heat dissipation process.
Innovation Solution
A fan frame with a waved structure on both the wind enter and exhaust sides, featuring alternating peaks and valleys, enhances airflow by improving wind rate and current, allowing for better heat dissipation through the fan's blades as they rotate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flat fan frame structure is used, then the device complexity is reduced and manufacturing is easier, but the wind rate and wind current are limited, resulting in reduced heat dissipation effectiveness
Solution Approach 1:
The fan frame employs a waved structure with curved surfaces instead of flat surfaces. The waved structure includes multiple waves that create a three-dimensional curved configuration, which enhances wind rate and wind current by improving airflow dynamics, thereby resolving the contradiction between structural simplicity and heat dissipation effectiveness.
2Productivity
If a flat wind enter side and wind exhaust side are used, then the manufacturing process is simplified, but the airflow is restricted, leading to limited wind rate and wind current
Solution Approach 1:
The wind enter side and wind exhaust side of the fan frame are designed with waved structures featuring multiple waves and curved surfaces. This curvature design enhances airflow characteristics, increasing wind rate and wind current while maintaining manufacturability through standard forming processes.
3Productivity
If conventional flat fan frame is used, then the structure is simple and cost-effective, but the heat dissipation effect is reduced due to limited airflow
Solution Approach 1:
The fan frame adopts a waved structure with multiple waves creating a complex three-dimensional shape. This curved configuration enhances wind rate and wind current by optimizing airflow paths, thereby improving heat dissipation effectiveness while accepting increased structural complexity.
