Description of the Invention: [Technical Field] [0001] The present invention relates to a heat dissipation system, and more particularly to a heat dissipation system in an electronic device. [Prior Art 3 [0002] Currently, computers play a very important role in people's lives. Moreover, the functions of the central processing unit and other components in the computer can not be ignored in the computer. Some important arithmetic processing done by the computer requires the central processor to complete these components. However, when these components of the central processing unit are working, heat is generated. If this heat is not removed in time, it will cause the temperature of the central processing unit to rise, which will affect its normal operation. [0003] The heat dissipation system in current computers places an air hood over the central processor to dissipate heat for the central processor. The air hood is capable of guiding the wind flow to accelerate heat dissipation to the central processing unit. However, this does not achieve very good results, and the central processor does not reduce much less heat. [Draft] [0004] In view of the above, it is necessary to provide a heat dissipation system with better heat dissipation effect. [0005] A heat dissipating system includes a heating element, an air guiding cover above the heating element, and a plurality of fans. The air guiding cover is provided with an air inlet and an air outlet, and the air inlet is provided with The fan, the air hood is provided with a fan on a side close to the air outlet, the fan is isolated from the heating element, and an air inlet and an air outlet 0992021397-0 of the air hood 099112072 Form No. A0101 Page 3 / Total 19 true 201138601 forms a wind flow channel for heat dissipation of the heating element. [0006] Compared with the prior art, in the above heat dissipation system, the air hood is provided with a fan on a side close to the air outlet for the air inlet and the air outlet of the air hood A wind flow path is formed to speed up heat dissipation for the central processor. [0007] Referring to FIG. 1, FIG. 2 and FIG. 3, a preferred embodiment of the heat dissipation system of the present invention includes an air hood 10 and a central processor located below the air hood 10. Not shown) and a plurality of fans 30. # [0008] The air hood 10 includes an air inlet 11 and an air outlet 12. The air hood 10 is provided with a hook 13 at a position above the air inlet 11 for fixing a system fan (not shown). The air guiding cover 10 is provided with two fixing bars 14 at the air outlet 12, and each of the fixing bars 14 is provided with a plurality of through holes 15. Referring to FIG. 4, the fan 30 is also provided with a plurality of through holes for engaging with the through holes 15 of the fixing strip 14 by a resilient fastener 40.
