Integrated Protection and Thermal Management Solution for CNLC Outdoor Displays

1. Overview

In the field of outdoor display technology, protection and thermal management are the two key factors that determine product stability and lifespan. Extreme conditions such as high temperatures, strong sunlight, humidity, dust, and heavy rain can all affect operational reliability.

CNLC adopts an integrated “protection + cooling” design philosophy, ensuring structural sealing, optical protection, and thermal performance validation through simulation. This guarantees stable operation under high brightness, long working hours, and diverse climate conditions.

This solution presents a systematic analysis of CNLC’s outdoor display technology, focusing on four core aspects:

• IP-rated waterproof and dustproof design

• Optical and protective performance of tempered glass

• Thermal simulation and temperature distribution results

• Aluminum structure housing and precision thermal management system

2. IP Waterproof and Dustproof Design Principles

CNLC’s outdoor displays achieve IP56 and IP66 protection ratings through precision-engineered sealing structures, silicone gaskets, waterproof joints, and corrosion-resistant connectors.

IP Ratings Definition:

• The first digit (0–6) indicates dust protection capability

• The second digit (0–9) indicates water protection capability

Technical Explanation:
The IP rating evaluates dust and water ingress protection, not the type of cooling system used.
Even in configurations with air inlets or outlets, CNLC employs sealed airflow channels, dust filters, and drainage design to prevent dust and moisture from reaching critical components.
Therefore, the inclusion of cooling vents does not compromise the IP56/IP66 protection level, maintaining reliable heat management and structural integrity.

3. Tempered Glass Protection and Optical Performance

CNLC outdoor displays utilize 6 mm or 8 mm tempered laminated glass, combining mechanical strength with advanced optical performance.
Available in ordinary and IR-filtered (infrared-blocking) configurations, these glass options use multilayer coatings to achieve spectral selectivity, balancing visible light transmission with solar heat rejection.

Technical Notes:

• Anti-Reflective (AR) coating reduces glare and environmental reflection interference.

• PVB/SGP interlayers ensure high optical clarity and UV stability, avoiding yellowing during prolonged outdoor exposure.

• Spectral selective filtering in IR glass minimizes solar heat gain, making it ideal for high-temperature or sun-exposed regions.

4. Thermal Simulation Analysis and Results

To verify the thermal stability of CNLC outdoor displays under high power and temperature conditions, a detailed thermal simulation was conducted.

Key Results:

• Surface temperature range: 39.40 °C – 71.29 °C

• Internal components: typically 60–70 °C, with a peak fluid temperature of 67.52 °C

• Heat distribution: uniform across LED modules, with no local hotspots detected

These findings confirm that CNLC’s cabinet structure maintains uniform thermal balance under full-load conditions, effectively preventing thermal stress and overheating.

5. Aluminum Structure and Precision Cooling Management System

Aluminum Cabinet Design:

• Constructed using 6063-T5 aluminum alloy (thermal conductivity ≈ 205 W/m·K)

• Lightweight yet robust for easy transport and installation

• Provides efficient heat conduction, maintaining uniform surface temperature

CNLC Precision Cooling System Features:

• Bottom air intake + dust filter: blocks airborne particles (applies to IP56 air-cooling models)

• Upward airflow + top exhaust fans: continuously expels internal heat

• Front-facing ventilation ducts: extract accumulated heat from the front of the display surface

• Smart temperature control system: monitors internal conditions and adjusts fan or A/C speed for optimal cooling, noise reduction, and extended component life

• Air-conditioning assist: IP66 A/C models employ bottom air intake/exhaust circulation for high-temperature or long-hour high-brightness environments

Thermal Management Performance:
Even under 1480 W power load and 800 W/m² solar irradiance, the system maintains stable and uniform internal temperature distribution, with surface temperatures between 39–71 °C.
This demonstrates CNLC’s ability to achieve efficient cooling without compromising IP56/IP66 protection, ensuring long-term operational stability of all internal components.

6. Application Scenarios and Customization

CNLC’s outdoor display systems can be customized across multiple dimensions:

• IP rating (IP56 / IP66)

• Cooling type (air-cooled / air-conditioned)

• Display size and brightness level

• Glass type (standard / IR-filtered)

• Housing structure and mounting method

Applicable environments include:
🌞 High-temperature desert climates
🌧️ Humid coastal regions
🏙️ Urban billboards with continuous high-brightness operation
🏭 Industrial zones with dust or corrosive gases
