Air Guide Vane Layout for Uniform Heat Sink Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric ranges face challenges in evenly cooling heat sinks and heat generation elements, leading to inefficient heat dissipation and potential overheating, particularly due to uneven air flow distribution.
Innovation Solution
The electric range incorporates a structured air guide system with vanes and divided flow paths to ensure even air distribution across the heat sink, featuring a vane that divides the air flow into two paths to cool both sides of the heat sink symmetrically, enhancing contact surface area and time for heat dissipation through slanted and plane parts with cooling fins and flow channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air blowing fan is used to cool heat sink, then cooling effect is improved, but air flow distribution becomes uneven
Solution Approach 1:
The air guide is divided into multiple flow paths (first flow path and second flow path) with separate air inlets and outlets. This segmentation allows independent control and optimization of air flow to different regions of the heat sink, ensuring uniform cooling across the entire heat dissipation surface.
Solution Approach 2:
The air guide acts as an intermediary component between the air blowing fan and the heat sink. It receives air from the fan and distributes it through multiple controlled flow paths, transforming the single-directional air flow into multi-directional uniform distribution across the heat sink surface.
2Power
If heat generation elements are disposed at heat sink, then heat dissipation capacity is improved, but cooling uniformity deteriorates
Solution Approach 1:
The heat sink is divided into multiple heat dissipation surfaces with corresponding flow paths. Each flow path directs air to specific regions where heat generation elements are disposed, ensuring that each element receives adequate cooling air flow. This segmented approach maintains cooling uniformity even with multiple heat-generating components.
Solution Approach 2:
Different regions of the heat sink are designed with optimized local flow characteristics. The air guide structure ensures that air flow distribution matches the thermal load distribution of heat generation elements, providing enhanced cooling to high-heat areas while maintaining uniform temperatures across all heat dissipation surfaces.
3Area of stationary object
If air guide surrounds heat sink, then cooling coverage is improved, but air flow resistance increases
Solution Approach 1:
The air guide is segmented into multiple independent flow paths with separate inlets and outlets. This segmentation reduces the length and resistance of individual air flow channels compared to a single large enclosure, while still providing comprehensive cooling coverage across the entire heat sink surface.
Solution Approach 2:
The air guide structure utilizes three-dimensional spatial arrangement with lateral walls extending in multiple directions. This dimensional approach allows air to reach all surfaces of the heat sink through optimized flow paths, maximizing cooling coverage while minimizing total air flow resistance through efficient geometric design.
