Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static electricity charged to a vehicle's radiator and condenser significantly affects cooling efficiency, but the mechanisms and methods to address this issue were not clearly understood, hindering effective static electricity management.
Innovation Solution
A vehicle cooling device is designed with a self-discharge static eliminator installed on a non-conductive wall surface of the connecting parts between the radiator, condenser, and fan cover, which reduces electric charges and improves static elimination, thereby enhancing cooling efficiency.

1Object-affected harmful factors
If the fan cover and radiator/condenser are made of non-conductive materials, then static electricity accumulates on these components, but this material choice provides electrical insulation and design flexibility
Solution Approach 1:
A self-discharge static eliminator is introduced as an intermediary component on the non-conductive wall surface. This eliminator acts as a mediator that selectively discharges static electricity from the fan cover and radiator/condenser surfaces while maintaining the overall non-conductive material structure and its insulation benefits.
Solution Approach 2:
The non-conductive surfaces are modified with localized conductive regions where self-discharge static eliminators are installed. This creates local quality variation - most of the surface remains non-conductive for insulation, while specific areas become conductive for static elimination, resolving the contradiction between material properties and static control.
2Productivity
If static electricity is discharged from the radiator or condenser, then cooling efficiency improves, but additional components and installation complexity are introduced
Solution Approach 1:
Self-discharge static eliminators are installed that automatically discharge static electricity without requiring external power sources, control systems, or manual intervention. The eliminators self-activate based on the presence of static charge, simplifying the overall system while improving cooling efficiency.
Solution Approach 2:
The self-discharge static eliminators use simple, inexpensive materials such as conductive adhesive tapes or metallic foils that can be easily applied and replaced if needed. These low-cost components provide effective static elimination without requiring complex or expensive systems.
