[Prior Art] Conventional heat dissipation modules are mainly used in the fields of electronics and optoelectronic products to eliminate the waste heat generated during the operation of electronic products. Its type is mainly passive heat sinking 70 pieces and active heat dissipating components. The former is copper or aluminum heat sink fins, while the latter is often the most economical micro axial flow fan, which forced the convection of the surrounding air of electronic products to reduce the temperature of the operating environment. . The conventional micro-axial fan structure 'includes an integrally formed hub 10 and a plurality of surrounding blades 20 (as shown in the figure) that are rotated by the motor-driven hub 10, even if the blade 20 generates a wind pressure to achieve a forced heat dissipation. Because the three-dimensional curvature, angle, number, and half-twist parameters of the fan blade will affect the values of wind pressure, pressure, noise, etc., the design scheme of the blade is good, so that several blades are in the front (front) direction. The void structure 'i.e., the leading edge of the blade is shielded from the trailing edge of the adjacent blade. However, the fan design of this structure will not be implemented due to the bottle head of the mold technology. Because of the partially shielded structure, after the injection molding, the bail-out will occur. Therefore, in the conventional axial fan structure, each blade retains a segment gap d' (as shown in the sixth figure), so that the injection molded fan can be denucleated, and the structure having the gap d is the wind. The sound and noise generated by the cutting noise are easy to cause insufficient wind pressure, and cannot fully meet the heat dissipation requirements. :M3 3 763 6 P·:/ I j > j [New content] The main purpose of this creation is to provide a combined miniature axial fan, which has its fan blades and hubs formed separately, and then combined with each other by assembly structure. Complete into an axial fan. With this structural design, the bottleneck of mold development can be overcome, so that the plurality of fan blades can be more tightly integrated around the hub, and even • the leading edge of one fan blade can be shielded on the trailing edge of the adjacent fan blade. The high and low position difference) forms a structure with no gap in the front angle of the fan, and reduces the noise during operation and the effect of increasing the wind pressure and air volume. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ a slot that opens toward the rear, and the outer wall of the near rear end is provided with a first predetermined positioning tooth along the circumference; and the fan blade is coupled with a wedge at the inner edge, and the front end of the wedge is provided with a tab to make the tab Inserting a hub slot, the inner surface of the wedge is provided with a second positioning tooth matching the first positioning tooth. The one end of the wedge is provided with a concave buckle groove, and the other end is provided with a convex fastening member, so that the wedges of the plurality of fan blades are fastened. An annular shape surrounding the hub, and a groove is formed on the outer end of the rear end of the wedge. When the plurality of wedges are fastened to surround the wheel-hub, an annular groove is formed, which can be embedded by a buckle. Buckle in the groove • The groove prevents scattering, thereby forming a complete combined micro-axial fan. [Embodiment] The structural features and other functions and purposes of the present invention are described in detail below with reference to the accompanying drawings.

The three-dimensional surface and geometry are not necessarily limited to specific, and can be modified into an optimal structural shape by aerodynamics. The inner edge 24 of each fan blade 2 is coupled with a wedge 25, and the wedge 25 can be formed in an arc shape matching the circumference of the hub 1. A tab 251 is disposed at the front end of the wedge 25 to make the tab 251 Inserting the slot 13 of the hub 1 and the inner surface of the wedge 25 is provided with a second positioning tooth 252 matching the first positioning tooth 15, the tooth opening of the second positioning tooth 252 may be a V shape or other shape; 25—the side end is provided with a concave buckle groove 253, and the other side end is provided with a convex fastening member 254 (as shown in the first figure and the second figure), thereby the wedges 25 of the plurality of fan blades 2 can be fastened to each other. An annular shape surrounding the hub 1; and a groove 255 ′ is formed on the outer end of the rear end of the wedge 25. When the plurality of wedges 25 are fastened to surround the ring of the hub 1, a ring of annular grooves is formed, and one can be reused.
