4. Performance Comparison: Extruded vs. Bonded Heatsinks
| Parameter | 350x80mm Extruded Heatsink | Bonded Heatsink |
|---|---|---|
| Thermal Conductivity | 205 W/m·K | 160 W/m·K |
| Max Operating Temp | 150°C | 120°C |
| Vibration Resistance | 50G (IEC 60068-2-6) | 25G |
| Lifespan | 15+ years | 8–10 years |
Extruded designs eliminate interfacial thermal resistance, offering longer lifespan and higher reliability.
5. Installation Guidelines & Best Practices
- Surface Preparation:
- Clean the mounting surface with acetone to remove contaminants.
- Thermal Interface Material (TIM):
- Apply a 0.1mm layer of non-silicone grease (e.g., Dow Corning TC-5625).
- Mechanical Fastening:
- Use M6 stainless steel screws (torque to 1.5 N·m) for even pressure distribution.
