Flared-Pin Heat Sinks Provide an Alternative for Natural Convection

Cool Innovations Inc. introduced a new line of powerful flared pin fin heat sinks that provide cooling power with their unique structure that was specifically optimized for natural convection environments. These 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 fins offer up to a 30 percent performance premium over traditional pin fin heat sinks, and a substantially larger cooling premium over the majority of other heat sink designs.

Flared pin fin heat sinks are forged from highly thermally conductive aluminum alloys. They are available in a wide variety of square, rectangular and round configurations, ranging in footprint from 1.0 x 1.0 inch to 5.0 x 5.0 inches, and in height from 0.7 to 2.0 inches. These heat sinks are a god fit 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
