Cooling Circuit Filter Geometry for Lower Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtration devices for cooling circuits are bulky, difficult to integrate, and costly to maintain, leading to pressure losses and irreversible damage due to complex welding methods and funnel-shaped configurations that impede fluid flow.
Innovation Solution
A removably mounted particulate filter with a conical or frustoconical bottom wall that converges towards the longitudinal axis, reducing pressure losses and facilitating easy installation and maintenance by guiding the cooling fluid effectively through the filter mesh.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a particulate filter is equipped to the cooling circuit, then particle accumulation is prevented, but the filter is bulky and difficult to integrate into engines
Solution Approach 1:
The filter element is nested within a housing that integrates directly into the cooling circuit connector. The filter mesh is contained within a cylindrical housing that fits into the connector body, allowing the filtration function to be embedded within the existing cooling circuit structure rather than adding a separate bulky component.
2Strength
If welding method is used to fix the filter system, then the filter is securely attached, but the method is long, costly and complex
Solution Approach 1:
The welding process is replaced with a mechanical snap-fit assembly system. The filter housing includes a mounting flange with holes that align with slots in the connector, allowing mechanical fastening through simple fasteners or clips instead of requiring welding operations.
3Ease of repair
If the second end of the filter has a funnel configuration, then particles are collected and discharged, but pressure losses occur in the cooling circuit
Solution Approach 1:
The funnel-shaped configuration is replaced with a cylindrical or slightly tapered housing that maintains a more uniform cross-sectional area along its length. This curved, streamlined shape reduces flow separation and turbulence, allowing particle collection at the bottom of the cylindrical housing without creating the pressure losses associated with sharp funnel angles.
4Stability of the object's composition
If the filter is permanently fixed in the connector, then the filter system is stable, but maintenance requires dismantling the entire filtration device
Solution Approach 1:
The filtration device is segmented into modular components: the filter element, the housing, and the mounting flange. The filter element is contained within the housing as a separate replaceable unit, allowing the filter to be maintained independently without removing the entire housing or connector assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for easy mounting and dismounting of the filter without significant pressure losses, ensuring efficient fluid flow and reducing maintenance complexity while preventing irreversible damage to the cooling circuit.
