The casing includes a first air inlet side and a second air inlet side parallel to a first direction, and an air outlet side adjacent to and perpendicular to the first air inlet side and the second air inlet side . The fan includes a hub pivotally arranged inside the housing and a plurality of fan blades extending radially outward from the hub, and each fan blade includes a fan blade that is connected to the first air inlet side and the second inlet side respectively. A first fan blade section and a second fan blade section on the wind side, the first fan blade section extends straight along the first direction, and the second fan blade section connects with the first fan blade section After extending straight along the first direction, it is bent to form a bent portion near the second air inlet side.

(5)具体实施方式(5) specific implementation

有关本实用新型的前述及其他技术内容、特点与功效，在以下配合参考附图的对较佳实施例的详细说明中，将可清楚的明白。The aforementioned and other technical contents, features and effects of the present utility model will be clearly understood in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

如图3、4所示，是本实用新型风扇装置3第一实施例，包含有一壳体31、一风扇32及一带动风扇32运转的马达33。壳体31形成有一基板311、三个延伸自基板311并界定有一容置室313的侧壁312以及一安装在壳体31上的盖板314，自基板311至盖板314间定义一第一方向，基板311上形成有一可供外界进风的第一开孔315，且于两相对侧壁312间界定出一出风口316，盖板314上也形成有一可供外界进风的第二开孔317，并分别定义第一、第二开孔315、317为第一及第二进风侧，且两进风侧沿第一方向相平行，另外定义出风口316为一出风侧，此出风侧与第一、二进风侧相邻且相垂直。As shown in FIGS. 3 and 4 , it is the first embodiment of the fan device 3 of the present invention, which includes a housing 31 , a fan 32 and a motor 33 for driving the fan 32 to run. The housing 31 is formed with a base plate 311, three side walls 312 extending from the base plate 311 and defining an accommodating chamber 313, and a cover plate 314 mounted on the housing 31, defining a first space between the base plate 311 and the cover plate 314. direction, the base plate 311 is formed with a first opening 315 for outside air intake, and an air outlet 316 is defined between two opposite side walls 312, and a second opening for outside air intake is also formed on the cover plate 314. hole 317, and define the first and second openings 315, 317 as the first and second air inlet sides respectively, and the two air inlet sides are parallel to the first direction, and define the air outlet 316 as an air outlet side, this The air outlet side is adjacent to and perpendicular to the first and second air inlet sides.

而风扇32具有一枢设于马达33的一输出轴331上且位于容置室313内部的轮毂321及多个由轮毂321径向向外延伸的扇叶322。前述马达33是固定安装于基板31 1上并容设于轮毂321内。配合参阅图5所示，各扇叶322具有相连接而分别接近第二、第一开孔317、315(即第二、第一进风侧)的一第一扇叶段323及一第二扇叶段324。第一扇叶段323沿第一方向平直地延伸，而第二扇叶段324则自与第一扇叶段323连接处接续沿第一方向平直延伸后，于接近第二进风侧处弯折形成一弯折部325，此弯折部325可形成完全平直状或弯弧状，在本例中是以弯弧状作说明，如此各第一扇叶段323构成离心式风扇的扇叶形态，而各第二扇叶段324则形成轴流式风扇的扇叶态样。The fan 32 has a hub 321 pivotally mounted on an output shaft 331 of the motor 33 and located inside the accommodating chamber 313 , and a plurality of fan blades 322 extending radially outward from the hub 321 . The aforementioned motor 33 is fixedly mounted on the base plate 311 and accommodated in the hub 321. Referring to Fig. 5, each fan blade 322 has a first fan blade section 323 and a second fan blade section 323 and a second fan blade section 323 connected to each other and approaching the second and first openings 317, 315 (ie, the second and first air inlet sides) respectively. Fan blade segment 324 . The first fan blade section 323 extends straight along the first direction, and the second fan blade section 324 extends straight along the first direction from the joint with the first fan blade section 323, and is close to the second air inlet side. Bending to form a bending portion 325, this bending portion 325 can be formed completely straight or curved, in this example is described as a curved arc, so that each first fan blade segment 323 constitutes the fan of the centrifugal fan blade shape, and each second blade segment 324 forms a blade shape of an axial flow fan.

另外，本实施例中各扇叶322由俯视方向观看，是如图6所示由轮毂321沿径向直线延伸，其转向则为逆时针方向，然而于变化例中扇叶322也可如图7所示由轮毂321沿径向呈弧形延伸。In addition, in this embodiment, each fan blade 322 is viewed from a top view direction, and as shown in FIG. 7, the hub 321 extends radially in an arc shape.

藉此风扇32旋动时，外界空气可分别由第一开孔315及第二开孔317进风，经第二开孔317输入壳体31的气流顺沿平直的第一扇叶段323垂直进风，同时由第二开孔317输入壳体31的气流则沿着弯弧状的弯折部325进风，且随着风扇32的旋转带动，这两股气流将均由出风口316排出(关于气流的流动方向如图5中各箭号所示)。In this way, when the fan 32 rotates, the outside air can enter through the first opening 315 and the second opening 317 respectively, and the airflow entering the casing 31 through the second opening 317 follows the straight first blade section 323 The wind enters vertically, while the airflow input into the casing 31 through the second opening 317 enters along the curved bending part 325, and driven by the rotation of the fan 32, the two airflows will both be discharged from the air outlet 316 (About the flow direction of the airflow as shown by the arrows in Figure 5).

本实用新型的风扇装置3结合离心式及轴流式风扇的扇叶形态，且使外界气流可由两进风侧大量进风，两股气流在扇叶32带动下，分别顺沿平直的第一扇叶段323及具有弯弧状弯折部325的第二扇叶段324而产生不同的气旋动，使得风扇装置3能保有离心式风扇特有的高风压特性，同时兼具轴流式风扇出风量大、噪音小的优点。The fan device 3 of the present utility model combines the shape of the blades of centrifugal and axial flow fans, and allows the external airflow to enter a large amount of wind from the two air inlet sides. Driven by the blades 32, the two airflows respectively follow the straight first The first fan blade section 323 and the second fan blade section 324 with the curved curved portion 325 generate different cyclonic motions, so that the fan device 3 can maintain the unique high wind pressure characteristics of the centrifugal fan, and at the same time, it can also be used as an axial flow fan. The advantages of large air volume and low noise.

After extending straight, it is bent to form a bent portion 426 near the first air inlet side.

如此，在风扇32旋动时，扇叶422的上、下端缘处会产生轴流效应，而于扇叶422中央处再形成离心效应，因此同样能具有高风压、高风量及低噪音的优点。In this way, when the fan 32 rotates, an axial flow effect will be generated at the upper and lower edges of the fan blade 422, and a centrifugal effect will be formed at the center of the fan blade 422, so it can also have high wind pressure, high air volume and low noise. advantage.

In this example, the electronic device 5 is a notebook computer, which has a main body 51 and a liquid crystal screen 52. The aforementioned fan device 3 is installed in the main body 51 . The host body 51 is provided with a plurality of existing electronic components (not shown), and the surface of the host body 51 has a plurality of inlets 511 that can correspond to the second openings 317 for air intake and a plurality of inlets 511 that can be connected to the first The opening 315 corresponds to the outlet 512 for air. When the electronic equipment 5 is in operation, the fan device 3 can perform air suction and exhaust functions as mentioned above.

归纳上述，本实用新型风扇装置3，藉由扇叶形成不同形态的两扇叶段，一扇叶段呈平直延伸，而另一扇叶段则于接近端缘处弯折形成一弯折部，使得风扇3旋动时，能同时兼具离心及轴流两种气流效应，进而具有高风压、高风量及低噪音的优点，因此，确实能达到前述本实用新型的目的。To sum up the above, the fan device 3 of the present invention forms two blade sections of different shapes by means of the blades, one blade section extends straight, and the other blade section is bent near the end edge to form a bent portion. When the fan 3 rotates, it can have both centrifugal and axial flow effects, and then has the advantages of high wind pressure, high air volume and low noise. Therefore, the above-mentioned purpose of the utility model can indeed be achieved.
