Referring to FIG. 1, a centrifugal fan i includes a __fan frame 11, an impeller 12, and a motor 11 #jl π (not yet). The fan frame 11 has an early-inlet air inlet ηι and a single air outlet, and is disposed in the fan frame, and has a plurality of wheel hubs 121 and a plurality of blades 122. The motor is disposed in the volute 121 β to connect and drive the impeller 12 to rotate. When the impeller 12 rotates, a flow enters from the air inlet (1), and after being pushed by the blades 122, the air outlet 112 flows out. Conventional centrifugal fans mainly rely on centrifugal force, so the wind pressure is relatively large compared with the axial flow fan, and the air volume is small. In order to improve the heat dissipation performance, the conventional technology increases the air inlet area by a double-sided air inlet centrifugal fan. The wind is k rising. However, the operation will be different due to the air inlet conditions on both sides. There is only a single outlet, so the airflow will interfere with each other and affect the heat dissipation effect. For example, the ambient temperature of one side air inlet is 3〇〇c, and the ambient temperature of the air inlet of the other side is 40°c. After entering the channel, the airflows are mixed with each other, causing the air outlet temperature to rise (between 30°C and 40°C). And the effect of the 1334898 heat effect. Therefore, how to provide a centrifugal air volume and improve the efficiency of the fan is the current important two-frame to increase the content of the invention. In view of the above problems, the object of the present invention is to provide a fan and a fan frame thereof to increase the air intake. , a kind of centrifugal energy, and the fan can be applied elastically. In several directions, the purpose of the invention is to improve the efficiency of the fan.

See the month and Figure 2, Figure 3, In the preferred embodiment of the present invention, the fan 2 includes a fan frame 21, at least an impeller 22, and a motor 23', and the frame 21 includes a frame body 211, 212 and a partition portion 213 (the motor 23 system) The frame 211, 212 or the partitioning portion 2i3 is illustrated as an example in which the motor 23 is disposed on the frame body 212 in the preferred embodiment, but is not limited thereto. The frame body 211 has an inlet. The air outlet 2111 has a air inlet 2124. The partition 213 is disposed between the frames 211 and 212 and is coupled to the frames 211 and 212 to form two independent airflow channels and two air outlets 2112. The partitioning portion 213 and the frame bodies 211 and 212 may be separate bodies. The partitioning portion 213 may also be integrally formed with the frame body 211 or the frame body 212. The partitioning portion 213 is, for example, a ring plate or a ring. The frame body 212 further has a bottom plate 2121 and a shaft tube portion 2122, 1334898 = the plate T is at least a connecting portion The shaft portion 2122 = ' is configured to constitute the air inlet 2124. The connecting portion 2123 can be a rib, a t-piece or a vane. Alternatively, the shaft portion 2122 can be modified into the tuyere 2124 as needed. The bottom plate (10) only needs to be formed in the fan frame 22, and includes a hub n. At least one partition 222 and at least one blade 223, 224, wherein the blades 223, 224 are different In the axial position, and corresponding to the two independent airflow passages respectively, the partition plate 222 is connected to the hub 221 and located between the two independent airflow passages. The blades 223 and 224 are respectively disposed on the partition plate 222. The two opposite sides, the fan blades 223, 224 'the partition plate 222 and the hub 221 may be separate bodies, or may be integrally formed. In addition, the side edges of the blades 223, 224 away from the hub 221 may be combined with the partition plate The outer periphery of the 222 is retracted, protruded or substantially flush, and the partition 222 is disposed corresponding to the partition 213 of the fan frame 21 such that the partition 213 is located between the blades 223, 224, and the The blades 223 and 224 respectively correspond to different airflow passages. The blades 223 and 224 are From a front rake, a rear rake, a flat leaf, and combinations thereof, and the settings of the blades 223, 224 may be equal or unequalized, for example, the airfoil, the number, the spacing, or the inclination angle may be the same or The motor 23 is coupled to the shaft tube portion 2122, and is coupled to drive the impeller 22 to rotate. Since the blades 223, 224, the air inlets 2111, 2124, and the air outlets 2112, 2125 are different flow passages, When the 1334898 motor 23 drives the impeller 22 to operate, the air inlet port is exhausted from the air outlet 2112 by the venting air flowing into the air vent 223, and the airflow flowing in from the air inlet 2124 is subjected to the fan blade. Driven by 224 and discharged from the air outlet 2125. Since the two air flow systems respectively flow in different passages, the two air flows do not affect each other. In addition, the air outlets 2112 and 2125 can adjust the assembly position and shape of the frame bodies 211 and 212 and the partition portion 213 to have the same air outlets in the same direction or different directions, so that the air outlets 2112 and 2125 have the same air outlet direction. (as shown in Figure 5) or not, for example perpendicular to each other, reversed (as shown in Figure 3) or formed at an angle. In this way, the fan 2 can dissipate heat from each of the heat dissipating objects according to the requirements. Referring to Figures 4 and 5, another centrifugal fan 3 of the preferred embodiment of the present invention includes a frame 31, an impeller 32, and a motor 23. The fan frame 31 includes two frames 311 and 312 and a partitioning portion 313. The frame body 311 has an air inlet 3111 and an air outlet 3112. The frame 312 is coupled to the frame 311 and has an air outlet 3125, a bottom plate 3121, and a shaft tube portion 3122. The bottom plate 3121 is connected to the shaft tube portion 3122 by a plurality of connecting portions 3123, and has an air inlet 3124. The connecting portions 3123 can be ribs, baffles or vanes. The impeller 32 is disposed between the two frames 311, 312, and includes a wheel valley 321, a partition 322, 323, and a plurality of blades 324, 325. The partition plates 322 and 323 are coupled to the hub 321 and have a gap between the partition plates 322 and 323. The partitions 322 and 323 are connected to the hub 321 , and the blades 324 and 325 are respectively disposed on the mutually distant sides of the partitions 322 and 1334898 323 . The blades 324, 325, the partitions 322, 323, and the hub 321 may be separate bodies or may be integrally formed. Alternatively, the blades 324, 325 may be located at different axial positions or may be located at the same axial position. The i-blade 4 313 is located between the partitions 322 and 323, and the partition 313 is coupled to the frame 311 and/or the frame 312. The motor 23 is connected to the shaft tube portion 3122, and is coupled to drive the impeller to rotate. Thus, when the motor 23 is in operation, two independent airflow passages can be formed so that the airflow in the fan does not affect each other. The air outlets 3112, ms, Γ, , #. can also adjust the assembly position and shape 该 of the frame body 312 and the partition portion 313: same or different, for example, perpendicular to each other, the reverse shaft tube portion 3122 It can also be changed to the upper part of the raft, and the air volume of the two fans can be increased to increase the heat dissipation effect. The utility model relates to a centrifugal fan and a fan frame according to the invention, which has an independent air flow passage, so that the air inlet can be increased, and the two independent air flow passages can be elastically applied (=fan effect different wind direction, etc.) respectively to provide heat dissipation effects.
