Claim:
A heat radiating fin assembly, comprising: a plurality of spaced alternately arranged and sequentially stacked first heat radiating fins and second heat radiating fins; each of the first radiating fins having a first flange and opposite second flange, a pair of first slant lateral edges extending from a first side of the first flange and a second side of the first flange, respectively; a pair of second slant lateral edges extending from a first side of the second flange and a second side of the second flange, respectively; each first slant lateral edge and each second slant lateral edge extend to join at a projection point, formed on a first lateral side and opposite second lateral side of the first radiating fin, the first flange, the second flange, the first pair of slant lateral edges, and the second pair of slant lateral edges, define the periphery of each of the first radiating fins, each of the second heat radiating fins having a first transverse edge and an opposite second transverse edge, a portion of the first transverse edge forms a third flange and a portion of the second transverse edge forms a fourth flange, a pair of third slant lateral edges extending from a first side of the first transverse edge and a second side of the first transverse edge, respectively; a pair of fourth slant lateral edges extending from a first side of the second transverse edge and a second side of the second transverse edge, respectively; each third slant lateral edge and each fourth slant lateral edge extend to join at a receded point, formed on the first lateral side and opposite second lateral side of the second fin, the first transverse edge, the second transverse edge, the third pair of slant lateral edges, and the fourth pair of slant lateral edges, define the periphery of each of the second radiating fins, the first and second lateral side of the first fin and first and second lateral sides of the second fin correspond such that the projection point and the receded point are alternately aligned together such that the projected points correspond to the receded points in alternate alignment to define an airflow guiding section in the heat radiating fin assembly with the first and second lateral sides of each of the first and second radiating fins having oppositely angled edges for encountering air flow in a manner that provides a wind shear effect; the airflow guiding section being defined on each longitudinal side, of the heat radiating fin assembly, and including a first airflow inlet formed at an upper portion thereof, a second airflow inlet formed at a lower portion thereof, and a middle airflow inlet formed between the and the second airflow inlet.
