Abstract
A heat dissipation device includes a base and a fastener. The fastener includes a neck portion, a head portion formed at one end of the neck portion, and an engaging portion formed at another opposite end of the neck portion. The base defines a receiving portion through the base. The receiving portion includes an inserting hole and a mounting hole communicating with the inserting hole. The engaging portion extends through the inserting hole from a top of the base to make the neck portion enter the inserting hole. The neck portion is then crushed into the mounting hole from the inserting hole. The engaging portion abuts the bottom side of the base at a periphery of the mounting hole. The head portion abuts the top side of the base at the periphery of the mounting hole.
