US 7,028,755 B2 · Heat dissipation device with interlocking fin plates

Abstract

A heat dissipation device (20) includes a plurality of individual fin plates (40) arranged side by side. Each fin plate includes a main body (42). First and second flanges (44, 46) extend perpendicularly from opposite edges of the main body of each fin plate. A pair of tongues (48) is stamped perpendicularly from the main body and is opposite to the first flange. A pair of projections (49) is stamped from the main body adjacent and opposite to the second flange. Protrusions (442) are formed at the first flange and holes (482) are defined in the tongues respectively. The tabs of a first fin plate are interlocked with the projections of an adjacent second fin plate. The protrusions of the first fin plate are received in the holes of the second fin plate. In similar fashion, all the fin plates are assembled together. The heat dissipation device is thus formed.

A heat dissipation device comprising:

a plurality of individual fins arranged side by side with one another, each of said fins comprising:
a vertical planar main body extending in a longitudinal direction;
an upper flange extending horizontally on an upper edge of the main body away from the main body in a first lateral direction perpendicular to said longitudinal direction;
a lower flange extending horizontally on a lower edge of the main body away from the main body in said first lateral direction and aligned with the upper flange in a vertical direction perpendicular to both said longitudinal direction and said first lateral direction;
at least one upper projection extending from at or near the upper edge in a second lateral direction opposite to said first lateral direction, the upper projection having a bridge-shaped configuration and cooperating with the corresponding main body to define therebetween a slit;
at least one lower projection extending from at or near the lower edge in said second lateral direction;
upper engaging means formed on the upper flange of one fin locked to the upper projection of a neighboring fin located in said first lateral direction;
and
lower engaging means formed on the lower flange of said one fin locked to the lower projection of said neighboring fin located in said first lateral direction;
wherein
said one fin and said neighboring fin are spaced from each other in said first lateral direction via the upper flange and the lower flange, and said upper engaging means is essentially downwardly assembled to the slit of the corresponding upper projection in said vertical direction.
