Server Heat Sink with Variable Fin Spacing

The patent applies local quality by making different heat sinks have different sizes according to their positions in the airflow path. Front heat sinks have smaller sizes while rear heat sinks have larger sizes, optimizing each location's heat dissipation capability based on local airflow conditions. This resolves the contradiction by adapting the heat sink properties to local requirements rather than using uniform sizes throughout.

The patent implements asymmetry by arranging heat sinks with non-uniform sizes along the airflow direction. The heat sink cross-sectional areas increase from front to rear, creating an asymmetric configuration that compensates for the decreasing airflow velocity and pressure along the flow path. This asymmetric arrangement ensures that rear heat sinks, which receive less airflow, have larger surface areas for effective heat dissipation.

The patent applies local quality by varying heat sink sizes according to their specific positions in the airflow path. Rather than uniformly increasing all heat sink sizes, only rear heat sinks are made larger where the airflow velocity is naturally lower, while front heat sinks maintain smaller sizes to minimize airflow resistance. This localized adaptation resolves the contradiction between heat dissipation area and airflow velocity.

The patent addresses the contradiction by transitioning from a one-dimensional uniform size approach to a multi-dimensional variable size approach. Heat sink cross-sectional areas are adjusted in the lateral dimension based on their position along the airflow direction, creating a gradient distribution that optimizes both heat transfer area and airflow passage without requiring uniform size increases throughout.
