Waterproof Display Heat Exchanger for Outdoor Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal displays (LCDs) designed for indoor use are not suitable for outdoor installation due to lack of protection against weather and dust, leading to heat buildup and potential blackout from inadequate cooling.
Innovation Solution
A display device with a housing that includes a waterproof structure, a heat exchanger on the rear surface of the display panel to collect heat, and a second heat exchanger outside the housing to release heat, ensuring effective cooling without increasing the device's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image display panel is arranged in the inside of a waterproof accommodation room to protect from weather and dust, then the display is protected from environmental damage, but heat cannot escape and the panel temperature rises causing blackout
Solution Approach 1:
The patent divides the thermal management system into two separate heat exchangers: a first heat exchanger positioned inside the waterproof accommodation room to collect heat from the display panel, and a second heat exchanger positioned outside the room to dissipate heat to the external environment. This segmentation allows the display to remain protected while heat is efficiently transferred and dissipated through the housing structure.
2Temperature
If cooling means is provided to the liquid crystal display to cool the image display panel, then the temperature is controlled, but the display increases in size
Solution Approach 1:
The patent combines the cooling function with the existing waterproof housing structure by integrating heat exchangers into the housing walls. The first heat exchanger is incorporated into the inner wall of the accommodation room, and the second heat exchanger is incorporated into the outer wall, allowing heat dissipation without adding separate cooling components that would increase the display volume.
3Length of moving object
If the display is designed for indoor use with thin profile, then the thickness is reduced allowing installation in narrow places, but outdoor installation capability is lost
Solution Approach 1:
The patent makes the display device universally adaptable to both indoor and outdoor environments by incorporating a waterproof housing structure with integrated heat exchangers. The same thin display unit can be installed outdoors with protective housing that provides both weatherproofing and thermal management, eliminating the need for separate indoor and outdoor display designs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for the reliable outdoor installation of LCDs by maintaining the display's functionality through efficient heat management, preventing temperature rise and ensuring the display remains operational in various environmental conditions.
Implementation Method 1
a heat exchanger collecting heat generated from the display panel
Implementation Method 2
a heat exchanger collecting heat generated from the display panel and arranged on the rear surface side of the display panel
Implementation Method 3
a second heat exchanger releasing heat collected by the heat exchanger to outside of the housing
Implementation Method 4
a second heat exchanger releasing heat collected by the heat exchanger to outside of the housing and arranged outside the accommodation room
