Solution Overview
Problem
Conventional filter elements in air conditioning systems have a small effective filter surface, leading to incomplete filtration of fluid flows, which can result in microparticles accumulating and causing long-term functional issues in heat exchangers.
Innovation Solution
A perpendicular flow type filter element with a large filter surface area is designed, featuring a hollow cylinder body and a base body that forms a structural unit with integral fixing and sealing means, allowing for efficient filtration and prevention of premature clogging, while being compact and easy to install.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional filter elements are used, then the device complexity is reduced, but the effective filter surface area is small leading to incomplete filtration
Solution Approach 1:
The filter element transitions from conventional planar filtration to three-dimensional perpendicular flow filtration. The hollow cylinder body creates a volumetric flow path where fluid enters through the side wall and flows perpendicular to the filter surface, maximizing the utilization of filter surface area while maintaining a compact cylindrical form factor.
Solution Approach 2:
The filter body is nested within the hollow cylinder body, with the filter surface positioned inside the cylindrical structure. This nested arrangement allows the filter element to achieve a large effective filter surface area while maintaining a compact overall dimensions, effectively packing more filtration surface into a smaller volume.
2Area of stationary object
If filter surface area is increased, then filtration efficiency is improved, but the package size increases
Solution Approach 1:
By implementing perpendicular flow through the hollow cylinder body, the filter element utilizes the volumetric space more efficiently. The flow path extends through the height of the cylinder rather than requiring a larger planar area, allowing increased filter surface area without proportionally increasing the overall package volume.
Solution Approach 2:
The filter body employs a thin-walled cylindrical structure that provides sufficient mechanical strength while minimizing material usage. The hollow cylinder body acts as a flexible yet rigid container that maintains structural integrity while allowing the filter surface to be positioned optimally for maximum filtration efficiency within compact dimensions.
3Reliability
If fixing means and sealing means assembly are formed on hollow cylinder body and filter body, then the installation reliability is improved, but the installation space is reduced
Solution Approach 1:
The fixing means and sealing means assembly are merged into a single integrated component formed on the base body. This consolidation eliminates the need for separate fixing and sealing components, reducing the overall number of parts and the space required for installation while maintaining reliable fixation and sealing functions.
Solution Approach 2:
The base body serves multiple functions: it provides structural support, forms the fixing means for mounting the filter element, and creates the sealing means assembly for fluid-tight sealing. This multi-functional design eliminates the need for additional dedicated components, optimizing the use of available installation space.
