Radiator Heat Shield Layout for Dashboard Electronics Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, heat from the radiator can inadvertently warm electronic components located behind it in the dashboard due to airflow, posing a risk of damage or malfunction.
Innovation Solution
A heat shield plate is strategically positioned between the radiator and the dashboard, inclined and sized to effectively deflect heated air away from the dashboard, with attachments to the vehicle body frame for stability, ensuring the shield's area covers at least half of the radiator fan's area and is positioned closer than the radiator's diameter to prevent heat from reaching sensitive components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the radiator is positioned frontward of the dashboard, then cooling efficiency is improved, but heated air from the radiator reaches the dashboard and damages electronic components
Solution Approach 1:
A heat shield plate is introduced as an intermediary component between the radiator and the dashboard. This heat shield plate reflects and redirects heated air away from the dashboard, preventing thermal damage to electronic components while allowing the radiator to maintain its frontward position for optimal cooling efficiency.
Solution Approach 2:
The space between the radiator and dashboard is segmented by introducing a heat shield plate. This divides the airflow path, creating a protected zone for the dashboard while maintaining the radiator's cooling function, thus resolving the conflict between cooling efficiency and thermal protection.
2Object-affected harmful factors
If a heat shield plate is added between the radiator and dashboard, then thermal protection is improved, but device complexity increases
Solution Approach 1:
The heat shield plate is designed as a thin, simple reflective barrier rather than a complex insulating structure. This thin-film approach provides effective thermal protection through reflection while minimizing added complexity, weight, and space requirements.
Solution Approach 2:
The heat shield plate is implemented as a simple, easily manufactured component that can be made from inexpensive reflective materials. This simple structure reduces manufacturing complexity and allows for easy installation and replacement if needed.
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 effectively prevents heated air from the radiator from reaching the dashboard, safeguarding electronic components and maintaining the structural integrity of the heat shield plate through secure attachment, thus protecting sensitive electronics from thermal damage.
Implementation Method 1
the heat shield plate may be inclined to extend obliquely rearward and downward from an upper edge of the heat shield plate. Accordingly, the air that receives the heat of the radiator can be effectively prevented from flowing obliquely upward toward the dashboard.

AI summary
A vehicle includes a radiator including a fan, a driving seat provided on a rear side of the radiator, a dashboard disposed on the rear side of the radiator and on a front side of the driving seat, and a heat shield plate disposed between the radiator and the dashboard. According to this structure, it is possible to prevent a device (for example, an electric component disposed on the dashboard) disposed on the rear side of the radiator from directly contacting air that receives heat of the radiator.
