Heat Sinks for Surface Mount Devices > Overview
- The most comprehensive line of pin fin heat sinks available today
- Heat sinks range from a footprint of 0.27" x 0.27" to a footprint of 2.5" x 2.5"
- Hundreds of extremely powerful copper and aluminum pin fin heat sinks are available for large, moderate and miniature SM devices
- Cool Innovations' pin fin heat sinks outperform the majority of other heat sink technologies by a substantial margin
- Pin fin heat sinks produce very low thermal resistances due to the round nature of the pins, large surface areas and an omnidirectional configuration
- Highly sophisticated and flexible manufacturing processes allow for a high degree of customization
- Cool innovations' heat sinks are lapped in order to reduce the contact resistance between the heat sink and the device
- Solutions are available in four distinct designs, each optimized for a specific airspeed environment
- Standard pin fins for SM devices range from a footprint of 0.27" x 0.27" to a footprint of 2.5" x 2.5" and from a height of 0.2" to a height of 1.7"
| Feature | Benefit |
|---|---|
| Round pin fin design | - Outstanding cooling power
- Low pressure drop |
| Omnidirectional structure | - Maximizes air intake
- Eliminates the need to control the direction of incoming airstreams |
| Highly conductive materials | - Additional cooling power due to higher thermal conductivity
- Superior heat spreading capabilities |
| Forging technology | - Ensures that no air bubbles, cavities or other impurities exist in the material |
| Lapped base finish | - Significantly flatter bases
- Reduced contact resistance between the heat sink and the device |
| Flexible manufacturing | - Allows the provision of custom pin fins (both footprint and height) without any tooling charges |
