Solution Overview
Problem
Existing LED light displays, particularly those used in outdoor environments, face challenges in managing heat dissipation effectively, leading to performance degradation and increased maintenance costs due to heat buildup and environmental exposure, which prior art methods such as fans and air conditioning fail to adequately address.
Innovation Solution
A housing design incorporating a heatsink plate with ribs forming heat sinks and channel members that allow heat to be dissipated through open channels to the external environment, utilizing conduction, convection, and radiation modes of heat transfer, without the need for air filters or additional cooling components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transparent materials such as glass are used for display cabinet walls to allow visibility, then viewing capability is improved, but heat dissipation deteriorates due to heat trapping within the cabinet
Solution Approach 1:
The cabinet wall is segmented into multiple sections: transparent sections for viewing and opaque/reflective sections for heat management. This allows the cabinet to simultaneously provide viewing capability and effective heat dissipation through different wall segments.
Solution Approach 2:
Different portions of the cabinet have different properties: transparent glass portions allow viewing while opaque portions with reflective surfaces or heat sinks provide localized heat management. The cabinet structure transitions from uniform transparency to differentiated zones with specific thermal properties.
2Temperature
If air cooling is used to dissipate heat from the display cabinet, then heat dissipation is improved, but dust accumulation in the interior deteriorates leading to performance degradation
Solution Approach 1:
The cooling function is extracted from the cabinet interior by placing heat sinks on the exterior surface of the cabinet. This allows heat to be dissipated externally without requiring air circulation that would introduce dust into the cabinet interior.
Solution Approach 2:
The cabinet wall acts as an intermediary thermal barrier, conducting heat from internal components to external heat sinks while preventing direct air contact between the interior and exterior environments, thus blocking dust ingress while maintaining thermal management.
3Temperature
If air conditioning is used to cool the display cabinet, then temperature control is improved, but device complexity and power consumption increase
Solution Approach 1:
The cabinet utilizes passive heat dissipation through externally mounted heat sinks that naturally dissipate heat to the surrounding environment without requiring active cooling systems, fans, or air conditioning equipment.
Solution Approach 2:
The mechanical cooling system (air conditioning) is replaced with a thermal conduction-based heat sink system that passively transfers and dissipates heat through the cabinet walls, eliminating complex mechanical components.
4Temperature
If external air is circulated through the display cabinet for cooling, then heat dissipation is improved, but environmental exposure to internal components increases
Solution Approach 1:
The heat dissipation function is extracted from the cabinet interior by mounting heat sinks on the exterior surface, allowing thermal management without requiring air circulation that would expose internal components to environmental factors.
Solution Approach 2:
The cabinet wall serves as a protective intermediary barrier that thermally couples internal components to external heat sinks while physically isolating the interior from environmental exposure to dust, moisture, and other contaminants.
