Watercraft Display Liquid Cooling System for Daylight Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays for watercrafts have low brightness and are difficult to see in daylight due to exposure to direct sunlight, and they often overheat, with reflective coatings intended to mitigate heat further reducing visibility.
Innovation Solution
A watercraft display with a liquid cooling system that maintains a brightness of at least 500 nits, eliminating reflective coatings, and includes a serpentine fluid flow path, a pump, and a heat exchanger to actively cool the display and other components, using a closed-loop system with ethylene glycol and deionized water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a reflective coating is applied to the display to mitigate external heat from the sun, then heat reflection is improved, but visibility in daylight is reduced
Solution Approach 1:
The patent removes the reflective coating from the display surface, extracting the harmful element that caused the contradiction. By eliminating the reflective coating, the display maintains full visibility in daylight while the liquid cooling system handles heat dissipation instead of relying on reflective surfaces.
Solution Approach 2:
The patent introduces a liquid cooling system as an intermediary between the display and external heat sources. The coolant circulates through channels in the mounting structure, absorbing heat before it reaches the display, thereby separating the heat management function from the display surface properties.
2Illumination intensity
If the display brightness is increased to improve visibility in daylight, then visibility is improved, but heat generation increases causing overheating
Solution Approach 1:
The patent converts the harmful heat generated by high-brightness display operation into a manageable thermal flow by directing it through the liquid cooling system. The coolant absorbs the excess heat, transforming the problematic thermal energy into a controlled heat transfer process that maintains display functionality at high brightness levels.
Solution Approach 2:
The liquid cooling system acts as an intermediary thermal management layer between the high-brightness display and the environment. The coolant circulation system intercepts and removes heat before it accumulates to problematic levels, enabling sustained high brightness operation.
3Temperature
If a liquid cooling system is added to cool the display, then overheating is prevented, but device complexity increases
Solution Approach 1:
The patent merges the cooling function with the existing display mounting structure. The cooling channels are integrated into the housing or mounting bracket that already supports the display, combining structural and thermal management functions into a single integrated component rather than adding a separate cooling system.
Solution Approach 2:
The liquid cooling system is designed to serve multiple functions: it cools the display, can potentially cool other electronic components in the watercraft, and integrates with the existing structural elements. This multi-functionality reduces the overall system complexity by using a single cooling infrastructure for multiple purposes.
