💡 Pro Tip: Understanding the Data
While no case provides the best heat dissipation, TPU cases offer the best balance between protection and thermal management, with only 1.3°C additional heat buildup compared to no protection.
🔍 Key Performance Factors
🌡️ Thermal Conductivity
Higher values = better heat transfer. TPU leads with 0.35 W/m·K maximum conductivity.
📏 Thickness Impact
Optimal range: 1.2-1.8mm. Thicker cases create thermal barriers.
🏗️ Design Features
Ventilation holes, surface textures, and internal structures enhance cooling.
🎨 Surface Area
Textured surfaces increase heat dissipation through improved air circulation.
