DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a fan and a fan thereof having an odd group of blade groups and an impeller thereof. [Prior Art] == Γ Γ 二 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高 高It has become an important part of the current development of electronic products. = Use = as a heat sink for the structure of the structure, see the schematic diagram of the conventional fan. The conventional fan 1 includes a two-six motor 11 and a fan frame 13. The impeller 10 and the motor 1 i I ::: the fan frame 13, the middle 'and the impeller 1 are composed of a plurality of blades (8) with a weight of 1 〇 2, and the fans # 101 are ring-shaped at the wheel valley 102# The two motors 11 are located inside the hub 102, and the impeller 10 is driven to rotate by the motor U. On the comparison, the Ding fan 1 design, the number of fans in the number of 101, the number of eighty-two can be designed to avoid fans! When rotating, the U-members such as the coil of the motor u and the ribs 131 of the group (1) 13 resonate, and many problems arise, such as the addition of sound, imbalance, and the fatigue of the bearing or other parts. This in turn affects the overall performance of the fan ί and reduces the fan! The service life of 200840947. However, as the heat dissipation demand increases, the slanting of the fan 1 requires the blade width of the blade 101 to be two: the improvement of the wind pressure is generally increased by increasing the angle between the adjacent blades 101. Increased air volume and job 'but due to the design of the phase. In addition, it is also limited by the wideness of the leaf surface and the high wind volume and the wind, the number of :::=, 101 is expected to mention the phenomenon. The resonance between the number of 4 and the number of components is one. How to provide a kind of wind-induced resonance phenomenon: "The kitchen is a kind of fan" and the "fan and the wheel that avoids production" is an important issue. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a wind and wind impeller. "The vibration phenomenon affects the efficiency and service life of the fan 4 to achieve the above purpose." According to the invention, the impeller is wrapped in;: = the odd-blade fan blade group. Among them, the fan blade group ring is set at the periphery of the And each fan blade group has a plurality of fan blades respectively. In order to achieve the above object, a fan system according to the present invention 4 includes a leaf wheel, a motor, and a fan frame. The impeller and the motor are all housed in the fan frame, and the vertical impeller has a trough and an odd number of fan blades, and the fan blade groups are further around the circumference of the wheel, and each fan group has a plurality of fan teas respectively. The motor is coupled to and drives the impeller. According to the above description, a fan according to the present invention and its impeller system will have a plurality of blades in 200840947, especially an even number of fans, and the number of blades is a number of fan blades. In the balance of the straw and the fan, the fan can maintain the balance of the odd-numbered blades and the wind: the same %, still limited to the design of an odd number of blades, and can avoid the "resonance phenomenon" that the invention does not produce. Therefore, there is a force in the fan blade group outside the even number of blades of the fan. This further increases the elasticity of the blade design. This is different or different because [the embodiment] will refer to the related drawings below. The present invention will be described in accordance with the preferred embodiments of the present invention. The same elements will be referred to by the same reference - 2A and FIG. 2B, which are preferred embodiments of the present invention. The frontal fish instead of the legislation - the wind winder...: According to the preferred embodiment of the invention, the planting fan 2 comprises an impeller 2〇, a frame 23, an impeller 2 () |, , up to 1, and a 2 In the fan frame, 23, and the Ma Jian 1 series link and drive苇 9 No. 9 is an axial flow type wind turbine. The fan 2 series fan of this embodiment. 勹, 艮田然 can also be - centrifugal 凊 while referring to Figure 2A and Figure 2C, Figure 2c schematic diagram. Impeller 2Q The system includes: the volute and the impeller in the mouth A. The fan blade group 22 is arranged on the hub 21 U solid fan 茱 group 22 series | has a circumference of $ / 丨, from -, and each blade peripheral ring is provided 221. In the present embodiment, the 'valley 21 has G1, G2, G3, G4, G5h_MWh 200840947 and the fan blade group 22 is shown at an equidistant interval of 2, and is surrounded by the periphery of the five blade group 軚21. As shown in Fig., the fan blade group 22 has two pieces: and: the outer periphery of the 21, each of the 4 221 is divided into an odd number of fan groups 22, not only because of the word: a plurality of fan blades 22 丨 design to produce an odd group, and Reduce the chance that not only the mouth == some of the other components of the fan 2 will resonate, the wheel H can contain multiple blades in the time and the middle, so the number of blades:: two leaves: the amount of increase. 'The wind of the fan is then limited to each; the second is limited to this'. For example, 9 blades of fan blades can be used for every 4 pieces, 3 sets of fan blades, or 12 pieces of ribs 3 One The three fan blade groups are formed. Therefore, the cofferdam of the present invention can satisfy the conditions of the "odd number of fan blades and each of the plurality of blades" ... with the system of the tethers, each of the fan blades 22 The fan blades 221 (four) disk L, that is, the blades 221a, 221b in each blade group 22: J, the curvature are different, as shown in Fig. 2C. Or, as shown in Fig. 3, the blade 30 The blades 32la, 321b' in each of the blade sets 32 are different from each other. However, the present invention is not limited thereto, for example, in Fig. 4, each of the blades 40 of the impeller 40 The shoulder blades and gammas in 42 can also be the same blade. In addition, according to actual needs, the adjacent blades 521a, 52lb of each of the blade groups 52 of the impeller 50 can be designed to partially overlap each other 8 200840947: as shown in FIG. Here, the fan having the impeller 50 can be applied to an electronic device having a light source, such as a projector or the like. Due to the partial overlap of the adjacent projections 茱 521a, 521b in the radial projection, the light emitted by the light source can be effectively blocked from transmitting outward and affecting the appearance. Bumai & Figure 6' is a different tilt of the household 1 according to a preferred embodiment of the present invention. In Fig. 6, the inclination of the blade 621a in each group 62 is different from that of the blade 621b, and the common angle & the inclination angle Θ1, the shoulder of the Θ2 is 6Γ 62 The fan blades 62la and 621b having the same gp @ + are provided on the hub 61 in such a manner that the fan blades having the same inclination angles θ1 and θ2 are disposed corresponding to each other. In addition to the difference in the inclination angle of the blade, the height of each blade 'connected to the hub can also be fixed 7; /' ie, the plurality of blades are located on different planes on the wheel. For example, the fan blade 7213 of the two fan blade group 72 is connected to the valley. Further, the height L2 of the lower portion 1b connected to the hub 71 is different. ^ j ° fan blade can also have the same airfoil curvature, as shown in Figure δ, each flat 钿μ a noon and have a thickness ThT2, respectively: T1 1 in the blade 821a, The fan blades of the 821b group are also not specifically designed for the T1. In addition, the blades in each of the blade % are long, as shown in Fig. 9 'each blade group is not equal to s?. _ has a chord length of 8 and 82, respectively, and 81 夂 夂 household & The side view airfoil of the (four) leaves may also be different; :: the fan group has more than two blade pitch systems which may not be equal to each other. Between the tea room and the emergency room 9 200840947 Please refer to Figure 1 〇, &#丄+ rim system and Fig. 2 = another leaf of the preferred embodiment differs in that the figure has similar composition and functional features, Each p^771tb, the wheel 2 further includes at least one reinforcing member 27, and the chemical member is connected to the reinforcing member 27 from each other. In detail, it is strong and f is disposed on the outer edge of the fan blade 221. The bristles are connected to the reinforcing member 27, so that: 荦:; 2 structural rigidity, if the blade 221 is too long, it can be fully changed. It has the problem of deformation at the end of the blade at the second turn. Further, the reinforcing member 27 can force the 221 of each blade to increase the stability of the impeller 26 when it is rotated. A leaf will be m'- the fan and its impeller provided by the present invention, which will be a plurality of fans: the special g丨I St A + will divide the even number of fan blades into odd arrays. The fans are busy with 7 fans and nfli. At^ 9 plus end k with the fan overall air volume and wind pressure::: can still maintain the balance of odd fan blades.
