Heat sink fin with joining structure
A heat sink fin with joining structure is provided, the heat sink fin is joined with and spaced from other heat sink fins mutually, so as to from a heat sink. The heat sink fin includes a plate and at least one inserting piece. The plate has at least one inserted slot formed in the plate near an edge thereof. The inserting piece extends from the edge of the plate corresponding to the inserted slot and has a buckled hole and a deformable buckling portion. The position of the inserted slot is corresponding to that of the inserting piece of another heat sink fin, and the inserted slot is provided for the inserting piece of the neighboring heat sink fin to be inserted into, and then the buckling portion of the heat sink fin is deformed and buckled into the buckled hole of the neighboring heat sink fin.
1 . A heat sink fin with joining structure, comprising:
a plate having at least one inserted slot formed in the plate near an edge of the plate; and
at least one inserting piece, extending from the edge of the plate corresponding to the inserted slot, and having a buckled hole and a buckling portion, wherein the inserted slot is provided for the inserting piece of another neighboring heat sink fin to be inserted into, and the buckling portion of the inserting piece of the heat sink fin is deformed and buckled into the buckled hole of the inserting piece of the neighboring heat sink fin.
2 . The heat sink fin with joining structure according to claim 1 , wherein the inserting piece perpendicularly extends from the edge of the plate.
3 . The heat sink fin with joining structure according to claim 1 , wherein the inserting piece comprises an overlapping portion on an end of the inserting piece away from the plate.
4 . The heat sink fin with joining structure according to claim 3 , wherein a height difference exists between the overlapping portion and the buckling portion.
5 . The heat sink fin with joining structure according to claim 4 , wherein the buckled hole is formed in the overlapping portion, and the overlapping portion is provided to lean against and overlap the buckling portion of the neighboring heat sink fin.
6 . The heat sink fin with joining structure according to claim 1 , wherein the buckling portion is cut in the middle thereof to form two buckling pieces to be deformed and embedded in the buckled hole.
7 . The heat sink fin with joining structure according to claim 6 , wherein the pressing piece is deformed into a rectangular bending angle to be embedded in the buckled hole.
8 . The heat sink fin with joining structure according to claim 1 , wherein the buckling portion is cut on an end thereof to form a buckling piece to be deformed and embedded in the buckled hole.
9 . The heat sink fin with joining structure according to claim 8 , wherein the pressing piece is deformed into a rectangular bending angle to be embedded in the buckled hole.
10 . The heat sink fin with joining structure according to claim 1 , wherein the buckling portion is a continuous piece, for being depressed and embedded in the buckled hole.
11 . The heat sink fin with joining structure according to claim 1 , wherein the plate has a flange formed on the edge of the plate that the inserting piece extends, and the flange extends on both side edges of the inserting piece.
12 . The heat sink fin with joining structure according to claim 11 , wherein the flange is perpendicular to the plate.
