Inductor Component Side Recess Structure for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inductor components face limitations in heat dissipation due to restricted heat release through their principal and side surfaces, necessitating improved thermal management.
Innovation Solution
The inductor component features recesses on its side surfaces with deeper depths than on the principal surfaces, increasing surface area and thermal conductivity while maintaining structural integrity and visibility, utilizing metal magnetic powder-containing resin for enhanced heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat is released from the principal surface and side surface of the component, then heat dissipation occurs, but the amount of heat released is limited by the surface area of the element body
Solution Approach 1:
The patent introduces recesses on the side surfaces of the element body, effectively adding vertical dimensionality to the heat dissipation surface. By creating stepped structures with different depth levels on the side surfaces, the patent increases the effective heat dissipation area without expanding the horizontal footprint of the component, thus resolving the contradiction between limited surface area and heat dissipation requirements.
2Temperature
If recesses are provided on the side surface with deeper depth, then heat dissipation is improved, but structural strength may be reduced
Solution Approach 1:
The patent applies local quality by providing recesses with different depth levels at different locations on the side surfaces. The recesses are strategically designed with varying depths (first level, second level, third level) to optimize heat dissipation in specific areas while maintaining structural integrity in other areas. This localized approach allows deeper recesses where heat dissipation is most needed while preserving strength in critical structural regions.
3Temperature
If recesses are provided on the principal surface, then heat dissipation is improved, but visibility and structural integrity are compromised
Solution Approach 1:
The patent employs asymmetry by concentrating the recess structures primarily on the side surfaces rather than symmetrically distributing them across all surfaces including the principal surface. This asymmetric arrangement prioritizes heat dissipation through side surface recesses while maintaining the visibility and structural integrity of the principal surfaces, which remain relatively flat and accessible for mounting and identification purposes.
