The first blade group extends downward from the periphery of the ring portion to the surface of the bottom plate. The first blade group and the second blade group are arranged in a staggered arrangement of up and down or left and right. 5 I267583 with or with two blades The number, shape or size of the fan blades of the group may be the first household firefly; and the second blade group is curved and curved. Alternatively, the blade is a mother-blade having a wing-like structure, and each of the second blade group is a non-special curved curved structure. The material is not connected; the other side is connected to each other, the part of the slave is on the same side or on the opposite side of the moving blade portion. The turret is preferably made of the ring portion, the bottom plate, and the body injection molding. Or a group frame frame, wherein the first frame has two frames. Wherein, the nth: the at least the air inlet is formed in the first empty frame wall of the fan frame: the inner frame of the fan frame extends r to define the set; the second place: the near Horizontally extending radially. The set: the flow of the collecting air channel, in addition to the second frame of the wind, the accumulation of a flow guiding structure is arranged at the base and:: has: the base, and has a plurality of wind, wherein the plurality of guides: 22: Two liters of the heat sink The plurality of flow guiding structures may be strips, lines or walls. Preferably, the plurality of guides are in the form of plates, curved or wing-shaped structures. Between the other portions, the two ends are respectively connected to the base portion and the wall portion is divided into discontinuities, and the free ends are connected to the base portion and the wall surface, and the middle portion of the plurality of flow guiding structures are more Between the four, the part is connected to the wall at the end and the knife is connected to the base and the end of the wall is connected to the base and the other end is the free end, and the other part is the free end of the horse. 6 1267583 > The plurality of flow guiding structures have an inclined angle, and the blade shape of the complex blade group is similar. ', y σ /, the moving blade portion additionally, the frame has a sleeve seat for the frame: ly the inner side In addition, the bearing has a common compression air passage. Preferably, the heat dissipating device can be a one-way centrifugal fan, a two-way human air blower or The axial flow type wind shoulder. The camera and the upside down structure are further provided. The heat dissipating device can additionally provide a flow guiding at the at least the air outlet. In addition, the heat dissipating device further comprises a driving device, and the sleeve seat is coupled to the moving blade portion. For driving the moving blade part: feather 1 - set small = according to this According to another concept, the heat dissipating device comprises a fan frame having: an opening; and at least one moving blade portion disposed in the fan frame, wherein each leaf J has at least a blade group, and wherein the group is different The height of the leaf edge is as follows: (4) The blade is ingeniously obtained by the following figures and detailed descriptions. [Embodiment] ^ See the figures of Figures 2 to 2C, which show the first preferred embodiment of the heat sink of the present invention. In this embodiment, a centrifugal fan is taken as an example, but the design can also be applied to an axial fan. The fan is a one-way wind type fan, which mainly includes a first a frame 21, a second frame 22, a driving device 23, an iron shell 24 and a moving blade portion 25. The first frame 21 has a set of seats 211, so that the driving device 23 can be placed thereon, and A bearing 231 is disposed in the sleeve seat 211 to support the rotating shaft 27 of the moving blade portion 25. The second frame 22 has an air inlet 221 and a wall surface 222 extending downward from the inner edge of the air inlet opening. After the second frame 22 is combined with the first frame 21, the second frame 22 and the first portion are 222 by the wall surface 222 The space formed by the combination of a frame 21 defines an airflow path 26 and a space for accommodating the bucket portion 25, and also forms an air outlet 212. The bottom end of the wall has a radially outward extension. The flange 223 = 7 l267583 is used to define an inlet 261 of the collection air passage. The bucket portion 25 is driven by the driving device 23 and is composed of a ring portion 251, a bottom plate 252, and a first blade group 253. And a second blade group 254, wherein the first blade group 253 and the second blade group 254 are composed of a plurality of blades, wherein the first blade group 253 is from the periphery of the ring portion 251 The lower portion extends to the surface of the bottom plate 252, and the second blade group 254 is disposed on the bottom plate 252. The arrangement of the first leaflet group 253 and the second blade group 254 may be staggered as shown in Fig. 2A. The air inlet of the second frame 22 is further provided with a base portion 224, and a plurality of flow guiding structures 225 are disposed between the base portion 224 and the wall surface 222 for increasing the wind pressure of the centrifugal fan. When the centrifugal fan is operated, the airflow is sucked from the air inlet 221, passes through the first blade group 2 53 and the second blade group 2 5 4 of the bucket portion, and passes through the collected airflow. The inlet 261 of the passage 26 guides into the collection air passage %, the port pressure and the gas storage to avoid the rapid change of the wind pressure, and then discharges the south air pressure air flow from the air outlet 212. f κ 财 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ;丄=The rapid change of force. In the axial direction of the bucket portion, 兮隹 &: the = and the guide: the height of the flow path of the structure can be two; the weight surface: the !_= wear (four) real change', and the work efficiency is lowered. This can avoid U being an area. In addition, the present invention employs a two-way motor in addition to placing the bearing 231 in the sleeve 2U, and the other is not in the base 224 of the second frame 22, In addition to 3, the bearing 232 is not the same as the 'the invention also uses the axial compression type air duct 29 == c biograph: 8 1267583 shows the size and shape of the 0 and the 253 and the nth group 254; ^ The composite fan blade design can also have the same as == *. In the arrangement::; complex and size may be the same or interconnected, partially connected or not at all in the middle, side or opposite side. For example, please refer to FIG. 3 , the first blade group 353 and the second blade group 354 may be disposed on the ring portion 351 of the 353th ring, and a blade group 3M is disposed on the bottom plate 352. Surface, ^ = j mesh; brother two leaf group curved structure, that is, each piece and there are two pieces: the piece presents a curved curve of the high and the second blade group V; 352, the first shoulder power; m is not the same. The ring portion 35 and the second blade group 354 of the ring portion 35 may be integrally formed into a body or the bottom plate 352 and the first blade group 353 may be taken together to form a complete one. Moving leaves. Alternatively, as shown in Fig. 3, the first blade group 353 and :] = 54 are connected to each other together, and both are in opposite directions. However, any changes and modifications are still within the scope of the patent. 1 is not off the hair flow - 2 5:: the structure is arranged at the air inlet, similar to the guide U 冓 28 can also be additionally set at the air outlet 212, as shown in Figure 4 = - curved Structure, and the number and shape of the flow guiding structure: different choices and changes depending on the actual application. In addition, if the case::: centrifugal fan, two-way air blower or axial fan, at the air inlet, or at the same time, it can be placed at each air inlet and two moving blades can be placed in it. . Finally, please refer to FIG. 5, which is a first preferred 1 257 583 of the heat sink of the present invention, and a conventional blower (==: just, the figure can clearly show the heat sink of the present case (4), The invention provides a heat dissipating device using a composite fan blade design, which can increase the fluid performance and thereby increase the heat capacity of the heat sink, thereby greatly increasing the heat dissipation efficiency. This case can be modified by people who are familiar with the art, but they are all protected as intended by the scope of the patent application.
