Description

Heat sink

The invention relates to a heat sink.

Radiators are often used to dissipate heat from electronic components of computer systems. However, with the development of the computer industry, the functions of electronic components are becoming more and more powerful, and the amount of heat generated is increasing. The heat dissipation of the heat sink is simply unable to meet the heat dissipation requirements. To do this, install a fan to actively dissipate heat. However, since the original heat sink does not have the structure of the stuck fan, the heat sink with the stuck structure has to be replaced, resulting in waste of the original heat sink.

In view of the above, it is necessary to provide a heat sink that can actively dissipate heat without replacing the heat sink.

A heat dissipating device includes a heat sink, a fixing frame for accommodating the heat sink, and a fan mounted on one end of the fixing frame, the fixing frame includes two combined portions and a plurality of fixing members, each combined portion including a side plate and a separate portion The two latching portions extend from the two sides of the side plate to the heat sink from the two sides of the heat sink, so that the latching portions are respectively blocked at the two ends of the heat sink and are correspondingly locked. The fan is mounted on the two latching portions at one end of the fixing frame through the fixing members, and each combination portion further includes a top plate extending from the top of the corresponding side plate, and the top plate of the two combined portions is blocked at the top of the heat sink Each of the top plates includes two extending pieces, wherein one of the extending pieces protrudes from one end of the corresponding side plate, and the other extending piece extends an extension away from one end of the corresponding side plate. The extension portion has a fastening groove for locking the protrusion of the other combination portion.

Compared with the prior art, the heat dissipating device is provided with a fixing frame for fixing the fan through the heat sink, and a fan can be added on the original heat sink to actively dissipate heat and improve heat dissipation efficiency.
