The relative angle between the axial direction of the plurality of protrusions 221 of the spoiler structure 22 and the plurality of heat dissipation fins 18 can be adjusted according to user requirements. Generally, the relative angle is substantially preferably a twist. Therefore, the airflow entering the plurality of heat dissipation fins 18 can disperse the airflow with the developed boundary layer flow field driven by the original fan 20 by the spoiler structure 22 and the surface texture of the spoiler structure 2 2 The airflow can be guided around the axis of the protrusion 221 to generate a spiral disturbance, thereby mixing with the main fluid flow field to generate an interactive transfer convection having a three-dimensional spatial flow directivity, and increasing the turbulence intensity of the airflow between the adjacent heat dissipation fins 18, In order to greatly improve the heat dissipation efficiency of the heat sink 12, and not greatly increase the system flow resistance, the influence of the air volume drop is excessive. In addition, when the heat dissipating device 12 accumulates dust on the side 11 M384303 (inlet end) of the plurality of heat dissipating fins 18 due to long-term use, the heat dissipating efficiency of the heat dissipating device 12 may be due to the flow path of the heat dissipating fins 18. The blockage has dropped dramatically. At this time, since the plurality of protrusions 221 of the spoiler structure 22 can extend into the respective intervals of the adjacent heat dissipation fins 18, the user can drive the rod 223 relative to the plurality of heat dissipation fins 18 by the knob 225. Rotating, the plurality of protrusions 221 of the spoiler structure 22 can rotate and remove the dust accumulated on the side of the plurality of corresponding heat dissipation fins 18 to clear the flow path between the adjacent heat dissipation fins 18. Please refer to FIG. 6. FIG. 6 is a schematic diagram of a plurality of heat dissipation fins 18 and a spoiler structure 30 according to the third embodiment of the present invention. As shown in FIG. 5 , in this embodiment, the spoiler structure 30 can be disposed on the heat dissipation fins 18 , and the spoiler structure 30 includes a plurality of protrusions 301 disposed adjacent to the heat dissipation fins 18 . On the side of the fan 20, the axial direction of the plurality of protrusions 301 and the heat dissipation fins 1·8 can be formed at an angle according to design requirements. For example, the angle is preferably 90 degrees. Therefore, the protrusion 301 can be used to disturb the air flow driven by the fan 20, thereby increasing the turbulence intensity of the airflow between the adjacent heat dissipation fins 18 to improve the heat dissipation efficiency of the heat sink 12. The spoiler structure 30 and the heat dissipating fins 18 may be integrally formed, and the position and number of the spoiler structures 30 may not be limited to the above embodiments, depending on the design requirements. In the third embodiment of the present invention, when the fan 20 drives the airflow from the side of the plurality of heat dissipation fins 18 into the gap between the plurality of heat dissipation fins 18, the plurality of protrusions 301 of the 12 M384303 spoiler structure 30 It can be used to destroy the airflow driven by the fan 20 with the developed boundary layer flow field, so that the airflow entering the gap between the plurality of heat dissipation fins 18 forms a vortex with a three-dimensional flow direction directionality, thereby increasing the adjacent heat dissipation fins. The turbulence intensity of the airflow between the pieces 18 increases the heat dissipation efficiency of the heat sink 12. Compared with the prior art, the heat sink of the present invention is provided with a spoiler structure at the air inlet end of a plurality of heat radiating fins without additional heat dissipating components to save manufacturing cost, which is used to destroy the fan. Driving the boundary layer flow field of the airflow, thereby increasing the turbulence intensity of the airflow entering the adjacent heat sink fins, thereby improving the heat dissipation efficiency of the heat sink, so the present invention provides a good and efficient heat dissipation solution.
