Settling Filter for Cooling Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooling systems in buildings and vehicles often suffer from contamination by solid particles such as sand, metal dust, and metal chips, which can lead to abrasive wear and clogging of cooling channels, resulting in premature component failure and decreased system efficiency.
Innovation Solution
A settling filter is introduced in the cooling system, which diverts a portion of the fluid flow into a network of closed 'dead end' chambers where the fluid velocity is reduced to zero, allowing solid particles to settle and be trapped, while returning the cleaned fluid back to the main flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is introduced in the cooling system to remove solid contaminants, then the reliability of the cooling system is improved, but the device complexity increases
Solution Approach 1:
The filter is divided into multiple chambers (first chamber, second chamber, third chamber) with separate fluid passages leading to each chamber. This segmentation allows the filter to handle large volumes of fluid while maintaining simple individual chamber structures, resolving the contradiction between reliability and complexity.
Solution Approach 2:
Multiple fluid passages are nested within the filter housing, with each passage leading to a separate chamber. The passages are arranged concentrically or in parallel within the housing structure, allowing complex filtration functionality to be achieved through nested simple passages rather than complex external structures.
2Object-affected harmful factors
If the filter removes solid contaminants from the coolant, then the harmful factors affecting the cooling system are reduced, but the fluid flow is diverted and slowed in the secondary passageway
Solution Approach 1:
The filter extracts solid contaminants from the coolant by diverting a portion of the fluid flow into secondary passageways where particles settle out. The cleaned fluid is then returned to the main flow, effectively removing harmful factors while maintaining overall system fluid velocity through the primary passageway.
Solution Approach 2:
Only a portion of the fluid flow is diverted into the secondary passageways for filtration, rather than all fluid. This partial action allows contamination removal while minimizing the impact on overall fluid velocity and system efficiency.
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 filter effectively removes solid contaminants from the coolant by utilizing gravity to settle the particles, preventing them from re-entering the fluid flow and thereby reducing the risk of component failure and maintaining system efficiency.
Implementation Method 1
a faster moving fluid is more able to keep a given particle in suspension than a slower moving fluid. In addition, when the fluid is at zero velocity, all particles that are more dense than the coolant will fall under force of gravity and settle at the lowest surface of the fluid passageway

AI summary
A fluid delivery system includes a primary fluid passageway and a filter that is configured to receive a portion of fluid that passes through the primary fluid passageway. The filter includes a secondary fluid passageway having a secondary inlet end that intersects the primary fluid passageway and a secondary outlet that intersects the primary fluid passageway at a location downstream of the inlet end. The filter includes a tertiary fluid passageway having a tertiary inlet end and a blind end. The tertiary inlet end intersects the secondary fluid passageway at a third location. The third location is disposed in the secondary fluid passageway between the secondary inlet end and the secondary outlet end, and the blind end disposed at a location spaced apart from the tertiary inlet end.
