Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving vehicles face challenges in effectively cooling external world information acquisition devices, such as camera modules, which can lead to performance degradation due to heat buildup, as conventional heat conduction cooling methods may not be sufficient.
Innovation Solution
The implementation of a bracket system that dissipates heat generated by external world information acquisition devices, such as LIDAR and cameras, to other devices like a rearview mirror, utilizing air flow from the air conditioner to enhance cooling efficiency, with the bracket being fixed to the moving body at an angle intersecting the air flow direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only heat conduction cooling by a heat conduction bracket is used, then the structure is simple, but the cooling performance is insufficient
Solution Approach 1:
The patent combines multiple cooling functions into a single bracket structure. The bracket simultaneously serves as a mounting structure and a heat dissipation system that integrates heat conduction, convection, and radiation cooling mechanisms, eliminating the need for separate cooling components while achieving superior cooling performance.
Solution Approach 2:
The bracket is designed to perform multiple functions: mechanical support for the external world information acquisition device, heat conduction pathway, convection surface for air flow cooling, and radiation surface. This multi-functional design reduces overall system complexity while enhancing cooling capability.
2Temperature
If the bracket is fixed to another device, then heat dissipation is promoted, but the structural stability may be affected
Solution Approach 1:
The bracket integrates the mounting function with the heat dissipation function by fixing to another device structure. This combination allows the bracket to serve dual purposes: providing mechanical support and acting as a heat sink, thereby promoting heat dissipation without requiring additional dedicated mounting hardware.
Solution Approach 2:
The bracket acts as an intermediary thermal pathway between the external world information acquisition device and the another device structure. It conducts heat away from the acquisition device while maintaining structural integrity through its design as a rigid mounting component.
