When the fan rotates, the fluid is pulled: moving, because the spacing 13 (ie, the flow path) between each blade 12 is large, so the fluid flows from. The distance between the sea and the plane of the machine is less than the amount of fluid directly affected by the surface of the blade 12, and the attendance of the iUi^ is small, and the fluid will flow out immediately after the axial outflow, and the flow of the fluid needle will flow out. , resulting in poor heat dissipation. In the shortcomings of the above-mentioned products, the creation of this case has exhausted its mentality. With years of experience in the industry, we have devoted ourselves to research and innovation, and finally successfully developed this "fan vortex booster". The case is actually an effect-enhancing creation. 5 M314797 [New content] 爰This is the ugly for the money to solve the problem, the partial area of the creation of the film overlaps, and in the blade of the self-supply, the leaf part, in order to increase the pressure of the fan and guide the fluid to the side of the wheel = The body inflow side is provided with a convex formation =:=: Γ for a _ by-lateral, the thermal element, and lies at the center of the bottom, and correspondingly - the fluid near the hub side follows the anger The end of the heating element ^ 丨 丨 for the purpose of 7, the creation of the "fans increase _ set", W Valley and a number of blades along the hub display, the number of wheels from one side to another - The side is tapered and protruded, and the protruding end is opposite to the center of the bottom, and the each-blade has a connecting end and a free end, and the four sides of the connecting end and the free end are divided into four sides. And a trailing edge, the connecting end is connected to the circumference of the rim and the free end is outwardly convex, the trailing edge of each blade is covered by a rim of the blade, and each blade is uncovered The exposed area is gradually increased from the connecting end to the free end, and a projection is provided on the side of the free end corresponding to the inflow direction of the fluid. The above object of the present invention, as well as its structural and functional features, will be described in accordance with the preferred embodiments of the drawings. [Embodiment] This creation department and: for a "fan thirst spin increase device", the picture is the creation of the M314797 preferred embodiment 'as shown in Figures 3 to 5, including - Valley 21 and plural Blades 22, ', medium. The rifle protrudes from the side to the other side to form a convex end 211. The protrusion k 211 is located at the center of the hub 21, and a middle section is formed in the volute 21 The two sides are connected to the aforementioned protruding end 211, and the middle portion 212 is convexly curved with respect to the center of the hub 21. Each blade 22 has a connecting end 221 and a free end 222, and a leading edge 223 trailing edge 224 is formed on both sides of the connecting end 221 and the free end 222 (as shown in FIG. 5), wherein 5 The hoisting end 221 is fixed around the volute 21, and the free end 222 is convex outward, and the trailing edge 224 of each blade 22 is concealed by the moon ί, 彖 223 of the next month. The uncovered area of the blades 22 gradually increases from the connecting end 221 to the free end 222, causing each of the blades 22 to be arranged in a spiral shape. The dry convex portions 225 are respectively disposed at the side ′ of the free end 222 of each of the blades 22 corresponding to the inflow direction of the fluid, and the convex portion 225 is erected with respect to the blade & The base 231 is pivoted in a frame 23. - the rotation of the wheel 21 and the blade 22 causes the fluid to flow from between the two blades 22, because the area of the blade 22 that is not covered near the connection end 221 is small, so that the fluid passing through the connection end 221 is subjected to less force. When the pressure is small, the area of the blade 22 near the free end 222 is not covered, so that the fluid excited by the fluid near the free end is subjected to a large force, and the reliance is large, that is, near the connecting end 221 side of the blade 22. The fluid force is small. 'The fluid near the free end of the blade 22 has a large force, so the fluid is large-side (4) small-side flow, that is, through the free end side M314797: ❸ fluid passes through the connection end 221 The side of the fluid flows in the direction, so that the outflowing fluid forms a concentrated converging effect, preventing the fluid from immediately spreading outward. Further, since the convex portion 225 is provided by the free end 222, the fluid "the closest to the free end 222 hits the convex portion 225 and changes the flow direction, and flows toward the connection end side 221. Referring to Figures 3 and 6, the above-mentioned fan frame 23 is fixed on a heat sink %, so that the convex end 211 of the hub 21 corresponds to the center of a heat generating component %, the hair # < The component 24 is, for example, in a politically hot state (as shown in FIG. 6) or a central processing unit (cpu) or the like, and the driving wheel 21 rotates, and the blades 22 drive the fluid from the frame to the base 231. The side enters, the other side of the heating element 24 flows, and the machine rainbow through the leaf = 22 forms the hub as described above. The side (or the connecting end of the blade 2^) is in the middle of the yaw (that is, the body is in a converging characteristic). In addition, the fluid near the hub a side is on the side of the hub 21, follows the middle portion 212 to the convex end 211, and then moves to the center of the government "", σ. 24 to solve the central portion of the radiator %. The highest heat-generating area # _ heat-dissipation problem, and thus greatly improve the heat-dissipation effect.
