The first heat-dissipating unit 丄 includes a first motor u fixed in the first fan frame 11 and a first fan blade part 13 fixed in the motor 12. The second heat dissipating unit 2 includes a second fan frame 2 connected to one side of the first fan frame 及 and a motor 22 and a second fan blade portion 23 provided in the second test 21 according to materials. The installation direction of the first fan blade portion 13 (that is, the installation direction of the air inlet and the air outlet) is the same as the second fan blade ρρ Μ. When the first fan blade portion 13 and the second fan blade portion 23 rotate at the same time, The first fan blade portion 13 can take in air and blow it out through an air outlet (not shown) of the second fan blade portion 23 to obtain a unidirectional airflow disturbance effect. However, in actual use, the The single-directional airflow disturbance effect is limited, and it cannot take away the heat temperature quickly. However, it has the disadvantage of poor heat dissipation. It is worth mentioning that, as shown in Figure 2, one of the second traditional 5 10 15 = heat radiation at a predetermined angle of rotation ... 〇, although the direction of disturbance can be changed, in fact, the heat radiating device 10 The unidirectional directional airflow jerky effect, the second case has poor heat dissipation. She also has [new content] Therefore, the purpose of this new model is to improve the heat dissipation effect of the wind mount. η—A kind of fan device capable of increasing airflow disturbance The fan device of the present invention includes a motor cover, a first horse, a first motor, a first fan blade portion, and a second fan blade portion. The motor housing is a shell with open ends ^ 'I, W Α and defines a receiving room. The first motor is fixed to one side of the valley housing chamber of the motor shaft and has a first turn toward the other end of the housing chamber. Side and Π "The second motor is fixed to the other side to the side and spaced away from the first motor, and has a second rotating shaft facing the other open end of the receiving room 萁 ρ. ^ ^" " . The first-Chu Yi ^ ± ^ ^ The second fan blade part of the second brother is consolidated on the second rotation shaft of the second brother; when the first and second motors are running, the first fan blade part and the second Fan blade # g _ I 1㈣W generates two axial airflows which are opposite to each other, which indirectly improves the airflow disturbance effect. [Embodiment] The foregoing and other technical contents, features, and effects will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings. 20 M253697 Please refer to FIG. 3 and FIG. 4 'a preferred embodiment of the novel fan device 3, which includes a motor cover 4 open at both ends, and a first fixed in the motor cover 4 at intervals. The motor 5 and a second motor 6, a first fan blade portion 7 and a second fan blade portion 8 5 which are fixed to the first motor 5 and the second motor 6, respectively, and a cover on the first fan blade. The part 7 and the fan shroud 9 on the second fan part 8 and a partition 100 which is fixed on an outer surface 44 of the motor cover 4 100 ° As shown in FIG. 4, the motor cover 4 The housing is open at both ends, and has two openings 41, and an accommodation chamber 43 defined by the surrounding wall 42. The first motor 5 is an accommodation chamber 43 fixed to the motor casing 4. One side is achieved in this embodiment by using a plurality of fixing members 1 through which pass through the motor cover 4 and are fixed on one side of the first motor 5; the first motor 5 has an orientation A first rotating shaft 51 at an open end of the receiving chamber 43. 15 The second motor 6 is fixed to the other side of the accommodating chamber 43 of the motor casing 4 and faces away from the first motor 5 at intervals. And the fixing member 110 fixed on the side of the second motor 6 is reached; the second motor 6 has a second rotating shaft 61 facing the other open end of the accommodation chamber 43; the first rotating shaft 51 and The second rotating shaft 61 is arranged to extend horizontally and oppositely. The first fan blade portion 7 is locked to the first rotating shaft 51 of the first motor 5 and is located on the left side of the motor cover 4. The opening 41 is outside and has first fan blades mostly at a predetermined inclined angle. 71. The second rotating shaft 61, the second fan blade portion 8 is locked on the second motor 6 M253697 and is located outside the right opening 41 "on the right side of the motor casing 4, and has a majority of the opposite to the first fan blade 71 When the first and second motors 5 and 6 are operated with the second fan blade at an inclined angle, the first fan blade portion 7 and the second fan blade portion 8 can be rotated at the same time to generate two axial air flows opposite to each other. 5 The fan blade guard 9 can cover the first fan blade portion 7 and the second acoustic blade portion 8. X-feather The partition plate 100 is fastened and fixed on the outer surface of the motor cover 4 with In order to isolate the air inlet positions of the first fan blade portion 7 and the second fan blade portion 8 to prevent the first fan blade portion 7 and the second fan blade portion 8 from sucking in 10 winds of each other during rotation. M The present invention may further include a support unit 12G ′ connected to the bottom of the motor 5 as an upright support. The support unit 12Q includes a support base 121 and a support vertically connected to the top of the support base 121. Frame 122; the support base 121 has a supporting riser 15 12U 'connected to the support frame 122 depending on the length of the support f 1211 As an upright fan device or a desktop fan device, the support frame 122 has two connecting portions connected to the bottom of the first motor 5 and the second motor 6, respectively, for upright support. When used, When the first motor 5 and the second motor 6 are running, the first fan blade portion 7 and the second fan blade portion 8 will be rotated at the same time by 20 minutes, so as to generate two axial air flows opposite to each other (such as The airflow arrow shown in FIG. 4) is different from the traditional heat dissipation device f shown in FIG. 1 and the heat dissipation device 10 shown in FIG. 2 only has a unidirectional airflow disturbance effect, which is better than the new model. The airflow turbulence effect can quickly take away the heat temperature and obtain the good heat dissipation effect of M253697. It is worth mentioning that if the new type fan device 3 is used in rotation, it can obtain the excellent airflow turbulence effect and achieve good heat radiation effect. However, the above is only one of the preferred embodiments of the new model. When 5 cannot be used to limit the scope of the new model implementation, that is, a simple equivalent change made according to the scope of the new patent application and the content of the new specification Modifications should still fall within the scope of the new patent.
