Solution Overview
Problem
Existing fixing structures for electrical components on substrates often compromise insulation and heat radiation performance due to stress on soldering portions and potential damage to coatings, especially in heavy components like coils, which can lead to vibration instability and reduced cooling efficiency.
Innovation Solution
A fixing structure that incorporates a separation member with a cooling gel and resin, allowing the electrical component to be isolated from the heat removing member while maintaining contact for heat dissipation, thereby preventing coating damage and absorbing vibrations, ensuring reliable insulation and heat removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the electrical component is positively brought into contact with the heat removing member to improve heat radiation performance, then heat radiation performance is improved, but stress acting on soldering portions can damage the soldering portions and coating
Solution Approach 1:
The patent introduces a soft material member as an intermediary between the electrical component and the heat removing member. This soft material member transmits heat from the electrical component to the heat removing member while preventing direct mechanical contact, thereby avoiding stress concentration on soldering portions and coating damage. The soft material member acts as a thermal conduit that decouples the thermal function from the mechanical constraint function.
2Temperature
If the electrical component is positively brought into contact with the heat removing member to improve heat radiation performance, then heat radiation performance is improved, but the coating of the electrical component can be damaged so that insulation performance is degraded
Solution Approach 1:
The soft material member serves as a protective intermediary that prevents direct contact between the electrical component and the heat removing member. This eliminates mechanical damage to the coating while maintaining thermal coupling through the soft material member, which conducts heat effectively without transmitting damaging forces.
3Object-affected harmful factors
If a soft material member is used to prevent direct contact and coating damage, then coating integrity is maintained, but heat radiation performance may be reduced
Solution Approach 1:
The patent specifies that the soft material member should have appropriate thermal conductivity parameters to ensure effective heat transmission. By carefully selecting materials with sufficient thermal conductivity (not too low), the system maintains good heat radiation performance while still providing mechanical protection. The thickness and material properties are optimized to balance thermal performance with protective function.
