Integrated Cooler Box Air Filtration for Compact Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air intake systems for work vehicles occupy excessive space in the engine compartment due to the configuration of primary and secondary air filters, which are not optimized for compactness while effectively filtering dust and particles in harsh agricultural environments.
Innovation Solution
The air intake system incorporates a cooler box with a screen for initial particle removal and a primary air filter assembly integrated into the cooler box walls, reducing spatial requirements by positioning the filter within the cooler box structure, allowing for efficient air filtration without the need for separate and bulky filter configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the primary and secondary air filters are positioned separate from the cooler box, then the air filters can effectively remove particles from the air, but the air intake system occupies a large amount of space within the engine compartment
Solution Approach 1:
The patent combines the air filter assembly with the cooler box by positioning the air filter assembly to define at least a portion of one of the walls of the cooler box. This integration merges two separate components (air filter and cooler box) into a single unified structure, reducing the overall space required in the engine compartment while maintaining the air filtration function through the integrated filter element.
2Volume of stationary object
If the air filter assembly is integrated into the cooler box wall, then the space usage in the engine compartment is minimized, but the air filter must effectively filter particles from air flowing through the cooler box
Solution Approach 1:
The patent applies local quality by positioning the air filter assembly to define a specific portion of the cooler box wall, creating a localized filtration zone within the integrated structure. The filter element is positioned to selectively remove particles from the air stream as it passes through the cooler box, ensuring effective filtration at the specific location where air enters or passes through the cooler box structure.

Function Achieved in This Case
This configuration minimizes space usage in the engine compartment while maintaining effective air filtration, ensuring clean air supply to the engine, even in dusty conditions, by integrating the air filter within the cooler box structure.
Implementation Method 1
a screen defining at least a portion of the first wall of the cooler box. The screen is configured to remove particles present in air entering the chamber of the cooler box
Implementation Method 2
an air filter assembly defining at least a portion of the second wall of the cooler box. The air filter assembly includes an air filter element configured to remove particles present in the air exiting the chamber of the cooler box
Implementation Method 3
one or more heat exchangers housed in the chamber within the cooler box, a supply line for providing a fluid from the engine to the one or more heat exchangers and a return line that conveys the fluid back to the engine

AI summary
In one aspect, an air intake system for supplying air to an engine of a work vehicle may include a cooler box having a first wall and a second wall, with the first and second walls at least partially defining a chamber within the cooler box. The air intake system may also include a screen defining at least a portion of the first wall of the cooler box. Furthermore, the air intake system may include an air filter assembly defining at least a portion of the second wall of the cooler box. The air filter assembly may be configured to remove particles present in the air exiting the chamber of the cooler box through the air filter assembly. The air exiting the cooler box through the air filter assembly may be supplied to the engine for combustion.
