How to layout the heat dissipation structure?
The three-level heat dissipation system forms a closed loop of thermal management:
- Modular heat dissipation : The thermal conductivity of aluminum-magnesium-zinc alloy box reaches 205W/m·K, 3 times faster than traditional materials
- System-level flow diversion : The honeycomb air duct design increases the air flow rate by 120%, and the actual measured cooling in tropical areas is 8-12℃
- Intelligent temperature control strategy : Built-in 50 temperature sensors, automatically switches active/passive cooling mode according to the environment
How to maintain stability in high temperature environments?
Three core technologies break through the problem of thermal decay:
- Graphene composite coating : Applied to PCB substrates, the thermal resistance value is reduced to 0.15℃·cm²/W
- Dynamic power regulation : At ambient temperature of 55℃, the system automatically reduces power consumption by 20% to maintain the display consistency
- Phase change energy storage materials : Implant paraffin-based material in the box interlayer, continuously absorbing peak heat for 4 hours
What are the differences in cooling solutions for special scenarios?
Customized heat dissipation design matches application requirements:
- Sports stadium screen : Increase dustproof filter and IP65 protection to ensure heat dissipation efficiency >85% in dusty environment
- Transparent display : Adopt a hollow structure design, maintaining 86% permeability while achieving heat dissipation performance of 2.5℃/W
- Floor tiles interactive screen : 30mm convection space is reserved at the bottom, and the air exchange capacity is still maintained at 1.5 tons.
How to verify the heat dissipation effect after long-term operation?
From Southeast Asian humid and heat projects to Middle East desert cases, the three-year tracking data shows:
- Temperature difference control : The surface temperature difference of the module is ≤2.5℃ to avoid regional chromatic difference
- Extended lifespan : Every time 10℃ lowers the operating temperature, the LED light source life will be extended by 2.8 times.
- Energy efficiency optimization : Intelligent temperature control system reduces overall energy consumption by 18%-22%
When choosing a heat dissipation solution, it is recommended to focus on the supplier's Thermal simulation test report and Actual environment operation data , truly achieve dual guarantees of display performance and equipment life.
