Abstract

A heat-dissipating fin assembly (1) includes a plurality of individual fin plates (12) arranged side by side. Each fin plate includes a main body (14). First and second flanges (16, 18) extend perpendicularly from opposite edges of the main body of each fin plate. A pair of spaced first bridge-shaped tabs (20) extends perpendicularly from the first flange toward the second flange. A pair of spaced second bridge-shaped tabs (24) extends perpendicularly from the second flange toward the first flange. Projections (28) are stamped from the main body opposing to the first and second bridge-shaped tabs. The tabs of each fin plate are interlocked with the projections of an adjacent fin plate. In this manner, all the fin plates are assembled together. The heat-dissipating fin assembly is thus formed.
