Electronic Housing Support for Engine Compartment Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of additional components within the engine compartment of vehicles often leads to thermal issues due to high temperatures, which existing solutions fail to adequately address while also aiming to minimize connection costs and optimize component placement.
Innovation Solution
An electronic box support is mounted in front of the wheel arch element with specific mounting points along the vehicle's lateral and longitudinal axes, utilizing a side member and spar for secure attachment, allowing for natural cooling and eliminating the need for additional cooling systems by positioning the electronic unit in a cooler area of the engine compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional components are integrated into the engine compartment, then vehicle functionality is improved, but thermal problems worsen due to high temperatures in the engine compartment
Solution Approach 1:
The electronic control unit support is positioned in front of the wheel arch element, utilizing the spatial dimension ahead of the wheel arch rather than within the traditional engine compartment volume. This dimensional relocation places electronic components in a cooler zone while maintaining vehicle functionality.
Solution Approach 2:
The support structure is specifically designed with mounting points on the wheel arch element and longitudinal member, creating a localized installation position that exploits the cooler thermal environment in front of the wheel arch compared to the hotter engine compartment core area.
2Temperature
If electronic components are positioned in cooler areas, then thermal stress is reduced, but connection costs and structural complexity increase
Solution Approach 1:
The wheel arch element serves multiple functions: it maintains its primary structural role for wheel mounting while simultaneously providing mounting points for the electronic control unit support. The longitudinal member also serves dual purposes as a structural component and a mounting platform, eliminating the need for dedicated separate support structures.
Solution Approach 2:
The electronic control unit support is merged with existing vehicle structures (wheel arch element and longitudinal member) rather than being a separate independent structure. This integration reduces overall structural complexity by combining multiple functions into existing components.
