Claim:
A heat sink element coupling structure ( 2 ), its single heat sink element plate comprised of an L-shaped plate having a horizontal fold formed along one lateral edge or a horizontally oriented U-shaped plate having horizontal folds formed along two lateral edges, including a minimum of one or more coupling structures disposed on the upper and lower or left and right sides or a certain position at the center portion of said plates, the features of which are: said coupling structure consists consisting of: an ascending-stepped or a descending-stepped horizontal offset formed on the lateral edge of said plates; an inverted U-shaped or a U-shaped appendage situated at the anterior section of said ascending-stepped or said descending-stepped horizontal offsets offset; one or two wing-shaped lock tabs formed at the two sides or either the left or the right side of said inverted U-shaped or said U-shaped appendage; when interconnected, one or two said wing-shaped lock tabs of each said coupling structure at the two sides of one heat sink unit (element) are fitted onto said ascending-stepped or descending-stepped horizontal offsets of the next correspondingly situated said heat sink unit (element) such that the one or two said wing-shaped lock tabs on said front heat sink unit (element) becomes engaged onto the lateral edge of the adjacent other said heat sink unit (element) at fixed horizontal distances and positions.
