Abstract

The modified fins at the leading edge of this heatsink design causes the stagnation pressure to be lowered at the fin tips due to smaller kinetic energy losses, which then translate into static pressure rises. Greater airflow velocities are also achievable, thus enhancing the heat transfer coefficients at the fin tip and surface area. The modifications to the fin edges can be incorporated at the vendor while the fins are machined.
