An exemplary heat dissipation device includes a heat sink, a fan holder, and a fan secured on a front side of the fan holder. The heat sink includes a base having two first fixing ears at its two lateral sides, and fins on the base. An engaging notch is defined in a top end of four of the fins. The fan holder includes a top panel, and two sidewalls extending downwardly from two lateral edges of the top panel. The top panel has a pair of inserting protrusions at a bottom surface thereof. The two sidewalls have two fixing flanges at lower ends thereof. The top panel is partially placed on the front portion of the top ends of the fins, and the inserting protrusions are inserted into the engaging notches of the fins. The two sidewalls abut against two lateral sides of the heat sink, and the two fixing flanges are disposed on the two first fixing ears.

Heat dissipation device having a fan holder

A heat dissipation device includes a heat sink, a fan holder, and a fan secured on a front side of the fan holder. The heat sink includes a base and fins on the base. An engaging groove is defined in top ends of the fins. The fan holder includes a top panel and two sidewalls extending downwardly from two lateral edges of the top panel. The top panel has an inserting protrusion at a bottom surface thereof. The two sidewalls have two latching legs at lower ends thereof. The top panel is partially placed on a front portion of the top ends of the fins, and the inserting protrusion is inserted into the engaging groove of the fins. The two sidewalls abut against two lateral sides of the heat sink, and the two latching legs fasten to two lateral sides of the base of the heat sink.

A locking device is used for securing a heat sink to an electronic device mounted on a first face of a printed circuit board which defines a first hole. The heat sink defines a second hole therein. The locking device has a fastener including a head portion located aside the heat sink, a foot portion located aside a second face of the printed circuit board, and a body portion extending through the holes of the heat sink and the printed circuit board and interconnecting the head portion and the foot portion. The foot portion includes a buckling part abutting against the second face of the printed circuit board, and a positioning part extending towards the head portion to a position above the buckling part. When the buckling part abuts against the printed circuit board, the positioning part has a portion thereof entering into the first hole.
