- The pin fin technology is considered to be the most powerful cooling technology available today.
- UltraCool pin fin heat sinks possess outstanding cooling properties. They generate very low thermal resistances per given volume, and at the same time, low pressure drop.
- UltraCool pin fins can be easily customized to meet application-specific requirements.
- The pin fin technology produces outstanding cooling solutions due to the round nature of the pins, an omnidirectional design and large surface areas.
- The omnidirectional design allows air to penetrate and exhaust the heat sink from every possible direction. At the same time, the round pins reduce resistance to incoming airstreams. The result is optimal intake of air into the pin array.
- Upon entry of the air streams into the pin array, the round nature of the pins creates turbulence within the heat sink. Turbulent air breaks the stagnant air boundary layers around the pins and as a result enhances the heat sink's thermal performance.
- As a result, the pin fin technology generates the best use of surrounding airflows. Combining this fact with the large surface areas that are typical to pin fins, results in the combination of low thermal resistances and low pressure drop.
- UltraCool pin fin heat sinks have been optimized to further improve the natural cooling power generated by the pin fin technology, both in terms of design and metallurgy.
- In term of design, UltraCool heat sinks have been configured to optimize air intake into the pin array. (Both pin densities and pin diameters have been optimized). UltraCool heat sinks are offered in three configurations that are each optimized for a specific airspeed range.
- In terms of metallurgy, UltraCool heat sinks are manufactured using highly conductive copper and aluminum alloys. The use of these materials provides a cooling premium and also improves the spreading of heat along the base. (UltraCool III heat sinks are manufactured from pure aluminum, UltraCool IV heat sinks are manufactured from oxygen-free copper).
- UltraCool heat sinks can be easily customized to meet application specific needs. Both footprint and height can be tailored to any given dimensions with no associated tooling charges.
