Power Conditioner Mounting Plate for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power conditioners used in households with photovoltaic or fuel cell power generation systems face challenges in achieving both secure wall mounting and efficient heat dissipation due to their heavy weight, which requires large mounting jigs, reducing the area available for heat dissipating fins and compromising heat dissipation efficiency.
Innovation Solution
A power conditioner design featuring a heat dissipating member with a mounting auxiliary plate of higher rigidity than the heat dissipating member, allowing for a larger area for heat dissipating fins without increasing the device's size, and a configuration that prevents direct heat transmission to the wall, ensuring secure mounting and improved airflow for enhanced heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If large mounting jigs are used to support the heavy power conditioner, then secure wall mounting is achieved, but the area for heat dissipating fins decreases
Solution Approach 1:
The mounting function is segmented from the heat dissipation function by introducing a separate mounting auxiliary plate. This plate carries the mounting holes and bearing structures, while the heat dissipating member maintains its full surface area for fins. The segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The mounting auxiliary plate acts as an intermediary between the wall and the heat dissipating member. It transfers the mounting load to the wall through dedicated mounting structures rather than requiring the heat dissipating member itself to bear the full mounting stress, thereby preserving its surface area for heat dissipation.
2Strength
If mounting holes are directly formed in the heat dissipating member, then secure mounting is achieved, but heat transmission to the wall increases
Solution Approach 1:
The mounting holes and mounting-bearing structures are extracted from the heat dissipating member and relocated to a separate mounting auxiliary plate. This extraction eliminates the direct thermal conduction path from the heat dissipating fins through the mounting holes to the wall, while maintaining secure mounting capability through the auxiliary plate's dedicated mounting structures.
Solution Approach 2:
The mounting auxiliary plate serves as a thermal intermediary that isolates the heat dissipating member from direct contact with the wall. Even though the plate itself may conduct some heat, it prevents the concentrated heat transmission that would occur through direct mounting holes in the heat dissipating member, and its larger surface area distributes thermal load more effectively.
