Heat Sink’s Design Cools More Effectively September 2005 Issue Published Date: September 08, 2005
A splayed-pin fin heat sink, the UltaCool P cools 20% to 30% more effectively than standard-pin fin heat sinks, in low air-speed environments and in natural convection mode. The heat sink is formed by an array of round pins that are splayed outwards. They have the same large surface area of conventional-pin fin heat sinks, but are not as densely configured. The sparse configuration allows air to enter and exit the pin array in a more efficient manner than with conventional heat sinks. They are forged from pure aluminum and oxygen-free copper. Standard footprint sizes range from 0.5" x 0.5" to 2.0" x 2.0". Heights range from 0.2" to 1.1". They are suitable for any surface-mount package type and come with pre-applied double-sided thermal tape as well as mechanical clips. COOL INNOVATIONS INC., Toronto, Ontario.
