Mini-pleat V Cell Filter Burst Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mini-pleat V bank filters suffer from lower burst strength, dust holding capacity, and structural integrity issues, particularly in high-pressure environments, leading to potential collapse and leakage, which is critical in applications like gas turbine air intake.
Innovation Solution
A single molded frame design with integrated plastic meshes and a polyurethane adhesive for the mini-pleat V cell filter, enhancing burst strength to withstand over 10,000 Pascal pressure and improving dust holding capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional multi-part plastic frames are assembled together, then ease of manufacture is improved, but structural integrity and burst strength deteriorate
Solution Approach 1:
The patent merges multiple separate frame parts (top panel, bottom panel, side panels) into a single monolithic plastic frame structure. This eliminates the need for assembly joints and potting agents, providing continuous structural support around the filter media while achieving burst strengths exceeding 10,000 Pa, compared to traditional assembled frames that max out at 6,200 Pa.
2Ease of manufacture
If traditional assembled frames with potting agents are used, then ease of manufacture is improved, but reliability and leakage resistance worsen
Solution Approach 1:
The monolithic frame design eliminates all assembly joints and potting agent interfaces where leaks could occur. The single-piece construction ensures continuous sealing around the filter media, preventing dust and moisture leakage even under high pressure differentials, thereby significantly improving reliability in critical applications like gas turbine air intake.
3Quantity of substance
If larger filter dimensions are used, then dust holding capacity is improved, but resistance to flow increases
Solution Approach 1:
The patent transitions from traditional flat panel filters to a three-dimensional V-bank configuration with pleated filter media arranged in a V-shape. This dimensional transformation increases the effective filtration surface area by approximately five times compared to flat filters of the same footprint, thereby increasing dust holding capacity while maintaining lower pressure drop and airflow resistance.

AI summary
The present invention discloses a mini pleat V cell filter assembly. The V cell filter assembly comprises a top panel, a bottom panel and a middle frame; all of which are manufactured in a single mold. The plastic meshes which are part of the single molded frame. Each wall of the V structure securely encloses the pleated filter for stronger burst resistance. The single molded mini pleat V cell filter assembly structure provides an higher burst strength estimated to withstand 10,000 Pascal or more of pressure.
