Power Supply Panel Filter Structure for Dust-Free Cooling Air
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems lack a means to prevent dust and impurities from entering via air inlets, leading to potential malfunction or damage of internal electronic components due to contamination.
Innovation Solution
A dust-proof filter structure comprising retaining plates, a frame, and filter cotton meshes is mounted on the power supply panel to filter incoming air, preventing contamination of internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an internal fan is used to draw external air for heat dissipation, then cooling efficiency is improved, but dust and impurities enter the power supply causing component contamination and malfunction
Solution Approach 1:
A filter cotton mesh is introduced as an intermediary component between the external air and the power supply interior. The filter mesh captures dust and impurities while allowing air to pass through, thus mediating between the cooling requirement and the contamination problem. The filter is held in place by a frame structure with retaining plates that secure it to the panel.
2Reliability
If a filter structure is added to prevent dust entry, then component protection is improved, but the structure complexity and manufacturing difficulty increase
Solution Approach 1:
The filter structure is segmented into distinct functional components: a frame providing structural support, retaining plates for mounting, and a filter cotton mesh for filtration. This segmentation allows each component to be optimized independently and facilitates assembly and disassembly for maintenance.
Solution Approach 2:
The filter cotton mesh is implemented as a flexible thin film that can be easily replaced. The frame structure provides a rigid boundary while the filter mesh itself is flexible, allowing it to conform to the frame and be easily installed and removed for cleaning or replacement.
3Object-affected harmful factors
If a fixed filter structure is used to block dust, then filtration effectiveness is improved, but maintenance and cleaning become difficult
Solution Approach 1:
The filter structure is designed to be dynamic rather than fixed. The frame with retaining plates allows the filter mesh to be easily inserted and removed. This dynamic design enables straightforward maintenance where the filter can be quickly taken out for cleaning or replacement and reinstalled without complex disassembly procedures.

Function Achieved in This Case
The filter structure effectively prevents dust from entering the power supply, prolonging its service life and maintaining normal operation while allowing easy cleaning and installation.
Implementation Method 1
The filter cotton mesh corresponds in shape to the window and is disposed in the window

AI summary
A dust-proof filter structure for a power supply panel is disclosed. The dust-proof filter structure is mounted to a front of a panel of a power supply. The panel has at least one air inlet hole. The dust-proof filter structure includes two retaining plates locked on two sides of the front of the panel. A frame is connected between the retaining plates and located on the front of the panel. The frame has a window corresponding in position to the air inlet hole. A detachable filter cotton mesh is disposed in the window. Thus, the cooling air flowing into the power supply can be filtered to prevent the components inside the power supply from being contaminated, so as to prolong the service life of the power supply and maintain the normal operation of the components. Besides, the filter cotton mesh can be quickly mounted and easily removed for cleaning.
