A new line of flared pin fin heat sinks have been introduced by Cool Innovations Inc., (Toronto, Canada) that are designed to provide enhanced cooling power performance due to an innovative structure that was specifically optimized for natural convection environments. Flared pin fins offer up to a 30 percent performance premium compared with traditional pin fin heat sinks, and a larger cooling premium over the majority of other heat sink designs.
The heat sinks feature a rugged array of round pins and are suitable for harsh industrial environments and outdoor applications.
Flared pin fin heat sinks feature an array of round pins that are slanted outwards. The sparsely configured staggered pin array and the flared structure combine to produce outstanding cooling power in natural convection. At the same time, the omnidirectional pin configuration ensures that the heat sinks operate efficiently in any orientation.
Flared pin fin heat sinks are forged from highly thermally conductive aluminum alloys.
The heat sinks are available in a wide variety of square, rectangular and round configurations, ranging in footprint from 1.0 inch x 1.0 inch to 5.0 inch x 5.0 inch, and in height from 0.7 inch to 2.0 inch. The new heat sinks are a suitable for emerging green technologies such as solar cells and advanced LED lighting, as well as any other applications and devices operating in natural convection environments.
