Description

风扇及风扇组件 Fan and fan assembly

技术领域 FIELD

[0001] 本发明涉及一种风扇及风扇组件,尤其涉及一种改善电路板配置的风扇及风扇组件。 [0001] The present invention relates to a fan assembly and the fan, the fan and particularly to a circuit board assembly disposed improved.

背景技术 Background technique

[0002] 随着电子产品的功能与运行速度提高,电子产品在运行时所产生的热能也相对增力口,为了维持电子产品正常运行,现有技术利用风扇作为散热装置,借助于气流强制散热,使电子产品维持正常工作温度。 [0002] As electronic products Function and faster, electronic energy generated during operation is relatively booster port, in order to maintain the normal operation of the electronic products, the prior art as a heat sink with a fan, by means of forced cooling air flow enable electronic products to maintain the normal operating temperature.

[0003] 图1为现有风扇的结构示意图。 [0003] FIG. 1 is a schematic view of the conventional fan. 现有的风扇I包括叶轮11、马达12以及扇框13,叶轮11及马达12被容置于扇框13内。 I include the conventional fan impeller 11, the motor 12 and fan frame 13, an impeller 11 and a motor 12 is accommodated within the fan housing 13. 其中,叶轮11具有轮毂111及连接于轮毂周缘的多个扇叶112,马达12包括转子结构121、定子结构122及电路板123,转子结构121连结叶轮11,且转子结构121与定子结构122对应设置,电路板123与定子结构122彼此电性连接。 Wherein the impeller 11 has a hub 111 and a plurality of blades connected to the hub periphery of the wheel 112, the motor 12 includes a rotor structure 121, stator structure 122 and the circuit board 123, the rotor structure 121 connected to the impeller 11 and the rotor structure 121 and stator structure 122 corresponding to provided, the circuit board 122 electrically from each other 123 is connected to the stator structure. 另外,定子结构122包括多个定子磁极122a,利用电路板123驱动定子磁极122a的电流方向使转子结构121转动,进而带动叶轮11旋转。 The stator structure 122 includes a plurality of stator poles 122a, 123 using the driving current direction of the stator pole 122a of the circuit board structure 121 rotates the rotor, so as to drive rotation of the impeller 11.

[0004] 由于现今对电子产品的效能及微型化的需求不断增加,因此,散热的需求也相对增加,鉴于此,如何提高风扇效能一直以来是产业界致力解决的问题之一。 [0004] With today on the effectiveness of and demand for miniaturization of electronic products is increasing, therefore, also an increased demand for cooling, in view of this, how to improve the efficiency of the fan has long been one of the industry to address the problem. 在现有技术中,通过缩小叶轮的尺寸或提高风扇的转速来提高风扇的效能,然而,此种设计通常需伴随较大的电流以驱动马达转动,换言之,需数量较多或体积较大的电子零件来驱动马达转动。 In the prior art, by reducing the size or increasing the rotational speed of the fan impeller to improve the efficiency of the fan, however, this design is usually accompanied by a large current required to drive the motor is rotated, in other words, a greater or larger number of required volume electronic components to drive the rotation of the motor. 在此种情况下,通常会导致电路板123的配置空间不敷使用,因此,必须在电路板123的外缘凸设凸柄123a以增加电子元件在电路板上的配置空间。 In this case, usually results in the configuration space of the circuit board 123 is enough for use, therefore, must protruding lug arrangement space 123a to increase the electronic component on the circuit board 123 of the outer edge of the circuit board. 然而,由于凸柄123a被非对称地设置在电路板123上,并自电路板123的周缘向外延伸,如此一来,凸柄123a会影响气流的流动方向及流量,进而产生紊流(turbulence)或润流(vortex),并使风扇运转时产生噪音,尤其对于小尺寸风扇而言,这种缺点更趋明显。 However, due to the lugs 123a are asymmetrically disposed on the circuit board 123 and extends outwardly from the peripheral edge of the circuit board 123, a result, lug 123a affects flow rate and the flow direction of the gas flow, thereby generating turbulence (Turbulence ) or fountain stream (Vortex), and noise during fan operation, especially for the small size of the fan, the more apparent this disadvantage.

[0005] 因此,提供一种可增加电路板的空间且不影响气流稳定性的风扇是当前的重要课 [0005] Accordingly, there is provided a space capable of increasing the circuit board does not affect the stability of the fan airflow is important current lesson

题之一。 One problem.
