Moving Dust Screen With Suction Channel for Work Vehicle Coolers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coolers in work vehicles, such as agricultural harvesters, face performance diminishment due to dust accumulation on cooler cores, which conventional dust removal methods fail to address effectively, as they rely on gravity and air flow, allowing re-entrainment of dust.
Innovation Solution
A dust removal assembly with a filter carrier that carries a filter through a suction region, utilizing a blower to create a suction channel that pulls captured particles into a channel for continuous removal, minimizing interference with the cooling air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rotating mesh is used to remove dust from the cooler surface, then dust can be dislodged from the mesh, but a significant amount of dust is pulled back into the cooler by the high air flow, negating the purpose of the mesh
Solution Approach 1:
The patent extracts the dust removal function from the main cooling air flow path by introducing a separate suction channel that draws dust-laden air away from the cooler cores. This separates the dust collection function from the cooling function, allowing dust to be removed without interfering with the primary cooling air stream.
Solution Approach 2:
The patent introduces a mesh carrier as an intermediary element that captures dust particles from the cooling air stream. The mesh carrier acts as a mediator between the cooling air and the dust particles, allowing the dust to be collected and removed separately while maintaining the cooling function.
2Object-affected harmful factors
If screens are used to trap dust, then dust accumulation on cooler cores is prevented, but the screens require removal for cleaning or replacement
Solution Approach 1:
The patent implements continuous dust removal by continuously moving the mesh carrier through the suction channel. This continuous motion allows dust to be constantly swept off the mesh and removed, eliminating the need for periodic maintenance or replacement of screens.
Solution Approach 2:
The patent transforms the static screen into a dynamic mesh carrier that moves continuously through the suction channel. This dynamic approach allows the mesh to self-clean as it moves, with dust being continuously removed by the suction channel, eliminating maintenance requirements.
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 continuously traps and removes dust and debris particles from the filter, maintaining cooler performance with minimal influence on the air stream produced by the cooling fan, ensuring effective heat dissipation.
Implementation Method 1
a blower fluidly coupled to the suction channel and configured to produce a suction region in and adjacent to the suction channel
Implementation Method 2
a cooling fan associated with the at least one cooler core to produce a stream of air across the at least one cooler core
Implementation Method 3
liquid-to-air coolers that direct relatively cool air across surfaces heated by the relatively hot liquid in order to remove the heat from the liquid
Implementation Method 4
a filter associated with the at least one cooler core such that the stream of air passes through the filter

AI summary
A cooler for a work vehicle includes at least one cooler core, a cooling fan associated with the at least one cooler core to produce a stream of air across the at least one cooler core, and a dust removal assembly including a filter associated with the at least one cooler core such that the stream of air passes through at least one collection surface of the filter. The dust removal assembly includes a suction channel placed such that it does not substantially interfere with the stream of air passing across the at least one cooler core, a blower fluidly coupled to the suction channel and configured to produce a suction region in and adjacent to the suction channel, and a filter carrier configured to carry at least a portion of the filter through the suction region such that particles captured by the filter are pulled into the suction channel.
