Off-Road Vehicle Fan Cooling Cargo Bed Front Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing off-road vehicles face challenges in effectively utilizing air sent by a fan in the engine room without reducing the degree of component layout freedom.
Innovation Solution
The off-road vehicle is designed with a fan positioned behind the cabin and ahead of the cargo bed, sending air toward the front wall of the cargo bed, which effectively cools heat generating objects and the exhaust assembly without obstructing component placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air sent by the fan is effectively utilized for cooling heat generating objects, then cooling efficiency is improved, but component layout freedom is reduced
Solution Approach 1:
The patent utilizes the vertical space between the cargo bed bottom wall and the engine room as a new dimension for component placement. The fan is positioned in this previously underutilized space, allowing it to send air upward to cool heat generating objects without interfering with the horizontal component layout. This dimensional approach resolves the contradiction by enabling effective cooling while preserving component layout freedom.
2Productivity
If the fan is positioned to send air toward heat generating objects, then cooling effectiveness is improved, but component placement flexibility is reduced
Solution Approach 1:
The fan is positioned to utilize the natural upward flow of hot air rising from heat generating objects. By placing the fan in the space between the cargo bed and engine room, it automatically receives hot air that rises and directs it for cooling, creating a self-service cooling system that enhances cooling effectiveness while maintaining flexibility in component placement.
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
This configuration allows for efficient cooling of heat generating objects and the exhaust assembly, utilizing the fan air effectively while maintaining the flexibility of component layout, thus enhancing the vehicle's performance and efficiency.
Implementation Method 1
The fan is provided in a space behind the cabin and ahead of the cargo bed, and is configured to send air toward the front wall of the cargo bed
Implementation Method 2
A fan and an outlet duct are mounted on the heat exchanger. The outlet duct is oriented to face the exhaust pipe so that air sent by the fan and discharged through the outlet duct cools the exhaust pipe
