Cyclone heat-dissipation fin assembly

Abstract

A cyclone heat-dissipation fin assembly includes a heat pipe and first and second arc-shaped heat-dissipation fin groups fixed thereon. The first and second arc-shaped heat-dissipation fin groups are in snap fit with each other along a vertical direction, and are configured to open in opposite directions. Each fin group includes at least one heat-dissipation fin stackedly arranged. A fan with multiple rotating blades is provided at a side of the heat-dissipation fin groups to generate a swirling airflow to the arc-shaped heat-dissipation fin.
