Heat dissipation device with fastener

A heat dissipation device, comprising:

• a base defining a receiving portion through the base, the receiving portion comprising an inserting hole and a mounting hole communicating with the inserting hole;
• and
• a fastener comprising a neck portion, a head portion formed at one end of the neck portion, an engaging portion formed at another opposite end of the neck portion, the engaging portion having a diameter smaller than that of the inserting hole, the head portion having a diameter larger than the diameter of each of the inserting hole and the mounting hole, the neck portion having a diameter smaller than the diameter of each of the inserting hole and the mounting hole, the engaging portion extending downwardly through the inserting hole from a top side of the base to make the neck portion enter the inserting hole, so that the head portion and the engaging portion are respectively located at top and bottom sides of the base, the fastener being then moved from the inserting hole towards the mounting hole, so that the neck portion is crushed into the mounting hole from the inserting hole, the engaging portion abutting the bottom side of the base at a periphery of the mounting hole, the head portion abutting the top side of the base at the periphery of the mounting hole.
