The central processor on the main board is the core of the computer system. When the computer is running, the central processor generates heat. Excessive heat can cause the central processor - not working properly. In order to effectively dissipate the heat generated by the central processing unit during operation, a heat sink is usually added to the central processing unit of the circuit board to dissipate the heat generated by the central processing unit. The heat device includes a heat sink H disposed on the electronic component, and the heat sink generally includes a soil seat, and the plurality of heat sinks are extended on the base, and the heat of the electron element is radiated to the touched air by dissipating the heat sink. in. In order to improve the heat dissipation efficiency of the heat sink, the radiator-side mounting-fan is used to blow the airflow generated by the fan into the passage of the heat-dissipating Korean film, thereby accelerating the heat dissipation of the heat sink. However, in the case where the fan is mounted on the heat sink, once the fan and the heat sink are not matched in size, for example, in the balance technology expansion structure ianar^TeChn〇1〇gyEXtended), the heat sink has a short, wide rectangular shape. , / wide, this is square or round 'fan can not cover the entire radiator, the gas generated by the fan & can not be evenly blown into the channel of the entire fin. The material f 1 - the method is to view the fan wire on the top of the heat sink 11, but the sulfur method makes the height of the whole device increase, and it is not suitable for the environment where the height is required to be recorded. SUMMARY OF THE INVENTION It is necessary to provide a fin-type gas that can be directed to the entire heat sink, including a button that is in contact with the stalking element, and a plurality of hoods placed on the bottom plate. The air hood has an air inlet and an air outlet, and the air outlet is disposed at the heat sink, and the air inlet σ and the air outlet 6 1310894 form a plurality of air flow passages; The fan is installed at the air inlet of the air hood; the airflow generated by the fan is blown toward the heat sink through the air passage and the air outlet of the S-window hood. The air guiding cover of the heat dissipating device of the present invention has an air inlet and an enlarged air outlet, so that the air guiding cover can be completely covered on the heat dissipating m side, so that the airflow generated by the fan is blown to the heat dissipating fin, and the heat dissipating device of the invention The air hood has a plurality of air flow passages, so that the airflow generated by the fan is divided into a plurality of regions and blown toward the heat dissipation fins, thereby improving heat dissipation efficiency.
