Power Supply Back Plate Heat Dissipation Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply devices face inefficiencies in heat dissipation due to the design of the power input and output ends, which restricts the flow of waste heat, leading to increased temperatures and reduced service life.
Innovation Solution
The improved structure incorporates a back plate with first heat dissipation holes and input/output holes, along with a protection cover featuring second heat dissipation holes, allowing for enhanced heat dissipation by minimizing the sheltered area and facilitating easy assembly/disassembly of power wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the plate member size is increased to accommodate more connecting ends, then the number of connecting ends increases, but the number of ventilation holes decreases and heat dissipation is blocked
Solution Approach 1:
The back plate is divided into multiple sections: a first plate member with connecting ends, a second plate member with ventilation holes, and a connecting portion. This segmentation allows the first plate member to accommodate power input/output ends while the second plate member provides dedicated heat dissipation pathways, resolving the conflict between connectivity and ventilation.
2Adaptability or versatility
If the plate member size is increased to accommodate more connecting ends, then the number of connecting ends increases, but the sheltered area increases and heat dissipation path is blocked
Solution Approach 1:
The back plate is divided into multiple sections: a first plate member with connecting ends, a second plate member with ventilation holes, and a connecting portion. This segmentation allows the first plate member to accommodate power input/output ends while the second plate member provides dedicated heat dissipation pathways, resolving the conflict between connectivity and ventilation.
Solution Approach 2:
The heat dissipation function is extracted from the first plate member and assigned to the second plate member. The second plate member is specifically designed with multiple ventilation holes to provide dedicated heat dissipation pathways, separating the connectivity function from the ventilation function.
3Ease of manufacture
If conventional power input/output structure is used, then assembly is simple, but heat dissipation efficiency is poor and service life is reduced
Solution Approach 1:
The power supply device is divided into modular components: casing, back plate with first and second plate members, power input unit with protection cover, and power output unit. This modular design maintains assembly simplicity while the second plate member's ventilation holes provide enhanced heat dissipation to extend service life.
