Vehicle Display Module Heat Sink Layout for Panel Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displays, such as liquid crystal displays and organic light-emitting diode displays, generate significant heat during use, which can lead to damage and reduce the service life if not effectively dissipated.
Innovation Solution
A display module with a heat-dissipation part comprising a main-heat-dissipation portion and a sub-heat-dissipation portion, where the main-heat-dissipation portion is partially overlapped with the display panel and connected to a blade structure in the sub-heat-dissipation portion, facilitating rapid heat conduction and dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If displays operate at higher brightness and diverse functions, then display quality and functionality are improved, but heat generation increases causing damage to internal electronic components
Solution Approach 1:
The patent converts the harmful heat generated by high-brightness displays into a beneficial cooling effect by using phase change material that absorbs heat during melting, transforming the harmful thermal energy into a useful thermal management mechanism that protects electronic components
2Temperature
If heat dissipation structures are added to displays, then heat dissipation effectiveness is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent merges the heat dissipation function with the display structure by integrating phase change material into the display panel layers, combining thermal management with the existing display architecture rather than adding separate cooling systems
Solution Approach 2:
The phase change material layer serves multiple functions simultaneously: it acts as a heat dissipation medium, provides structural support between layers, and maintains the display panel's integrity, eliminating the need for dedicated cooling components
