Heat Sinks for Power Devices > Overview
- Standard heat sinks range from a footprint of 2.4" x 2.4" to a footprint of 9.8" x 9.8"
- Exceptional cooling power is packed into a low profile envelope (0.6" to 1.7")
- A wide array of highly-powerful pin fin heat sinks are available for power 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
- Solutions are available in two designs, each optimized for a specific airspeed environment
- Sparsely configured pin fins are designed for airspeed environments ranging from 0 to 400 LFM
- Densely configured pin fins are designed for airspeed environments ranging from 400 to 800 LFM and for impingement cooling (fan placed directly on top of the pins)
- 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
- Standard pin fins for power devices range from a footprint of 2.4" x 2.4" to a footprint of 9.8" x 9.8" and from a height of 0.6" 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 |
| 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 |
