Stackable Louver Panel With Tortuous Airflow for Spray Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional louvers in arc process devices fail to adequately prevent liquid spray from entering the device housing, leading to potential damage of electrical components due to bouncing or ricocheting, and additional protective measures obstruct airflow.
Innovation Solution
A louver panel comprising a plurality of overlapping louver modules that create a tortuous path for airflow while preventing contaminants, using fluid guides and wings to guide airflow and block contaminants, with a support member for assembly and attachment to the device housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional downward-angled fins are used in louvers, then air can flow through the openings, but liquid droplets or spray can bounce off the fins and enter the component housing
Solution Approach 1:
The louver is divided into multiple segments: an upper louver portion with upwardly extending fins and a lower louver portion with downwardly extending fins. This segmentation allows each portion to perform its specialized function - the upper portion intercepts incoming spray while the lower portion maintains airflow, resolving the contradiction between airflow efficiency and contaminant prevention.
Solution Approach 2:
The invention adds a vertical dimension to fin orientation by having the upper fins extend upwardly while lower fins extend downwardly. This dimensional change creates a more effective barrier against spray while maintaining airflow paths, as the upward fins intercept contaminants from above while the downward fins guide air flow underneath.
2Reliability
If additional protective measures are added to prevent liquid spray entry, then component protection is improved, but airflow is obstructed
Solution Approach 1:
The bi-directional louver structure performs multiple functions simultaneously: it prevents liquid spray entry, maintains airflow, and protects components without requiring additional separate protective measures. The upward fins in the upper portion and downward fins in the lower portion work together as a unified system that achieves both protection and airflow.
Solution Approach 2:
Different portions of the louver have different fin orientations optimized for their specific locations - upward fins in the upper portion for spray interception and downward fins in the lower portion for airflow maintenance. This local differentiation allows each region to perform its optimal function without compromising the other.
3Ease of manufacture
If a single-piece sheet metal or injection molded louver is used, then manufacturing is simplified, but adequate prevention of liquid spray entry cannot be achieved
Solution Approach 1:
The louver is segmented into an upper louver portion and a lower louver portion that can be manufactured separately and then assembled together. This segmentation enables each portion to be optimized for its specific function while maintaining manufacturing feasibility, resolving the contradiction between manufacturing simplicity and contaminant prevention effectiveness.

Function Achieved in This Case
The louver panel effectively prevents contaminants from entering the housing while maintaining sufficient airflow for cooling, thus protecting internal components and improving cooling efficiency without obstructing airflow.
Implementation Method 1
a louver panel for an arc process device having a plurality of louver modules that define a tortuous path from an upstream side to a downstream side of the louvered panel. The tortuous path permits a flow of gas (e.g., air) and prevents contaminants from traveling through the louver panel.

AI summary
A louver panel for an arc plasma device. The louver panel includes several louver modules that define tortuous paths from an upstream side to a downstream side of the louvered panel, and a support member coupled to the louver modules. The tortuous paths permit flows of gas and prevent contaminants from traveling to the upstream side. A louver module includes a frame, a first fluid guide supported by the frame, and a second fluid guide extending from the first fluid guide.
