The bracket includes a plurality of rivets and clasps. Each of the clasps includes a mounting portion, an arm extending upwards from the mounting portion, and a hook portion extending from a top end of the arm and towards the mounting portion. The mounting portion is riveted on the bracket by a corresponding rivet. The fan includes a plurality of ears corresponding to the clasps. The hook portions of the clasps abut on top surfaces of the ears to fix the fan on the bracket. The fan defines a plurality of channels communicating the outlet of the fan. ## Claims ### Claim 1 A heat dissipation device comprising: a bracket comprising a plurality of rivets and clasps, each of the clasps comprising a mounting portion, an arm extending upwards from the mounting portion, and a hook portion extending from a top end of the arm and towards the mounting portion, the mounting portion being riveted on the bracket by the corresponding rivet; a fan having an air inlet and an air outlet, the fan comprising a plurality of ears corresponding to the clasps, the hook portions of the clasps abutting on top surfaces of the ears to fix the fan on the bracket; and a heat sink mounted on the bracket and having a plurality of channels communicating the air outlet of the fan. ### Claim 2 (depends on 1) The heat dissipation device of claim 1, wherein each of the ears defines a through hole, the bracket comprising a plurality of orientating members each extending in the through hole of a corresponding ear. ### Claim 3 (depends on 2) The heat dissipation device of claim 2, wherein each of the orientating members comprising a circular base contacting a bottom of the corresponding ear and a pin extending from a top end of the circular base and in a corresponding through hole of the corresponding ear. ### Claim 4 (depends on 2) The heat dissipation device of claim 2, wherein the bracket comprises a plurality of position blocks, each of the position blocks being spaced from the corresponding rivet and abutting against the arm of the corresponding clasp. ### Claim 5 (depends on 4) The heat dissipation device of claim 4, wherein the bracket, the rivets, the position blocks and the orientating members are integrally made of metal. ### Claim 6 (depends on 4) The heat dissipation device of claim 4, wherein the bracket is made of plastic material, and the rivets, the position blocks and the orientating members are integrally made of metal with bottoms embedded in the bracket. ### Claim 7 (depends on 1) The heat dissipation device of claim 1, wherein the bracket comprises a bottom plate and two side plates extending upwards from opposite edges of the bottom plate, two air guiding plates inwards extending from inner sides of the side plates from the fan to the heat sink. ### Claim 8 (depends on 7) The heat dissipation device of claim 7, wherein the bottom plate defines an opening communicating the air inlet of the fan and a window receiving the heat sink, the opening and the window being defined at two sides of the air guiding plates. ### Claim 9 A heat dissipation device comprising: a bracket comprising a plurality of rivets, clasps, and orientating members, each of orientating member being spaced from and adjoined to one corresponding rivet, each of the clasps being riveted on the bracket by the corresponding rivet; and a centrifugal fan having an air inlet and an air outlet, the fan comprising a plurality of ears corresponding to the clasps, the clasps abutting on top surfaces of the ears to fix the fan on the bracket. ### Claim 10 (depends on 9) The heat dissipation device of claim 9, wherein each of the orientating members comprising a circular base contacting a bottom of a corresponding ear and a pin extending from a top end of the circular base and in a corresponding through hole of the corresponding ear. ### Claim 11 (depends on 9) The heat dissipation device of claim 9, wherein the bracket comprises a plurality of position blocks, each of the position blocks being spaced from the corresponding rivet and abutting against a corresponding clasp. ### Claim 12 (depends on 11) The heat dissipation device of claim 11, wherein the bracket, the rivets, the position blocks and the orientating members are integrally made of metal. ### Claim 13 (depends on 11) The heat dissipation device of claim 11, wherein the bracket is made of plastic material, and the rivets, the position blocks and the orientating members are integrally made of metal with bottoms embedded in the bracket.
