Description of the invention (3) The cooling fins 2 3 1 make the fan 2 1 set on the heat sink 2 3 ′ and then on the chip 2 4 1 of the circuit board 2 4. Please read again. Figure 5 as shown in Figure 5. When the blade portion 2 1 2 of the fan 21 is rotated by the driving portion 2 1 1 a, the air flows to the joint surface 2 of the driving portion 2 1 1 a. The flow under 1 1 d increases the area where the radiator 23 is in contact with the airflow, and further improves the heat dissipation effect. Please refer to the seventh figure again. As shown in the figure, the positioning portion 2 1 1 b can be provided with an inclined wind deflector 2 1 1 f to pass the fan blade portion 2 1 2 through the driving portion 2 1 1 a. The airflow generated by the action is quickly sent below the joint surface 2 1 1 d.
