Description

Combination mechanism for heat dissipation and fastening device used therefor

technical field

The utility model relates to a heat dissipation combination mechanism and a fastening device used therefor, in particular to a fastening device for fixing a heat dissipation device on a CPU support.

Background technique

Please refer to FIG. 1A and FIG. 1B , which are heat-dissipating fasteners of a conventional computer central processing unit (CPU). When assembling, use the two buckle holes 111 at both ends of the U-shaped clamp 11 to buckle with the hooks 121 on both sides of the CPU base 12 to fix the heat sink 13 and the CPU on the CPU base 12 . The U-shaped clamp 11 exerts a downward pressure on the heat sink 13 in a bridge-like manner, so that the heat sink 13 is in close contact with the CPU, and the CPU is positioned on the CPU base. However, since the elastic force of the U-shaped clamp will weaken as the number of times of use increases, the heat sink cannot be firmly fixed. Furthermore, when assembling, the buckle hole at one end of the U-shaped fixture must be fastened to a hook portion of the CPU base, and then the buckle hole and the hook portion at the other end must be fastened together, thereby causing a relatively large force on one end and making the CPU The surface is damaged by uneven application of external forces.
