Heat sink with interlocked fins

A method for assembling a heat sink having interlocked fins, the method comprising the steps of:

• a) providing a base plate;
• b) providing a plurality of fins, interlocking means arranged between the fins;
• c) placing a first one of the fins adjacent a second one of the fins;
• d) moving laterally either or both of the first and second fins until the first fin is interlocked with the second fin;
• e) assembling all other of the fins to the second and/or first fins in like manner to the procedure described in steps c) and d);
• and
• f) mounting the assembled fins to the base plate.

A heat sink, comprising:

• a base made from a heat conductive material and defining a top surface;
• a plurality of fins extending from the top surface of the base;
• and
• interlocking means arranged between the fins such that each fin is interlocked with adjacent fins from a lateral direction which is parallel along an edge of the fin.

A heat sink comprising:

• a base plate defining a lengthwise direction thereof;
• a plurality of fins mounted on the base plate in a parallel relation along said lengthwise direction, each of said fins extending in a transverse direction perpendicular to said lengthwise direction;
• said fins assembled with one another in said transverse direction, each of said fins including a planar main body with a spacing member integrally extending therefrom in a lengthwise direction, said spacing member including a horizontal portion extending from the main body partially with a slit therebetween, and a vertical portion extending from said horizontal portion;
• wherein
• when assembled, a junction portion of said vertical portion and said horizontal portion of one fin is received in the slit of an adjacent fin, and said vertical portion of said one fin abuts against the main body of said adjacent fin opposite to the main body of said one fin, so as to retainably spatially assemble said one fin and said adjacent fin together.
