Solution Overview
Problem
Existing vehicle controllers face challenges in managing heat dissipation due to increased heat generation from high-specification circuit components, with limitations in applying heat dissipation structures across different specifications and vulnerability to moisture ingress, especially in water-cooling systems.
Innovation Solution
A dual cooling structure that selectively uses air-cooling or water-cooling types based on the central processing unit's temperature and overload conditions, incorporating a cooling system with air-cooling and water-cooling devices, and a temperature sensor to manage coolant flow through a cover top.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a water-cooling structure is applied to dissipate heat from high-specification controllers, then heat dissipation performance is improved, but vulnerability to moisture ingress increases
Solution Approach 1:
The system dynamically switches between water-cooling and air-cooling modes based on real-time temperature monitoring and overload conditions. The controller selects the appropriate cooling method adaptively, enabling the system to utilize water-cooling for superior heat dissipation when needed while avoiding moisture-related risks in normal operating conditions.
2Device complexity
If a heat dissipation structure based on low-specification controllers is applied, then device complexity is reduced, but heat dissipation performance becomes insufficient for high-specification controllers
Solution Approach 1:
The heat dissipation apparatus is designed with multi-functionality to serve both low-specification and high-specification controllers. It incorporates both water-cooling and air-cooling capabilities within a single system, allowing the same apparatus to adaptively provide appropriate cooling levels based on the controller's specification and thermal requirements.
3Object-affected harmful factors
If air-cooling is used instead of water-cooling, then moisture resistance is improved, but heat dissipation performance decreases
