Description
技术领域 technical field
本发明涉及一种风扇。 The invention relates to a fan.
背景技术 Background technique
请参照图1，现有的风扇80通常包括一扇框81与一收容于扇框81内的叶轮83。扇框81的中部为一横截面呈圆形的用以收容叶轮83的内壁光滑的容置孔85。叶轮83转动，气流从容置孔85的一侧进入容置孔85后经叶轮83作用由容置孔85的另一侧向四周发散地吹出。对于需要风流集中散热的元件，此风扇80的散热效果并不好。 Referring to FIG. 1 , the conventional fan 80 generally includes a fan frame 81 and an impeller 83 accommodated in the fan frame 81 .

如下具体实施方式将结合上述附图进一步说明本发明。 The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.
具体实施方式 Detailed ways
请参照图2与图3，本发明风扇10的较佳实施方式，包括一扇框12及一叶轮14。 Referring to FIG. 2 and FIG. 3 , a preferred embodiment of the fan 10 of the present invention includes a fan frame 12 and an impeller 14 .
该扇框12包括相对的两侧壁121。该扇框12的中部设有一横截面呈椭圆形的贯穿该两侧壁121的容置孔123。该叶轮14装设于该容置孔123内。该扇框12于该容置孔123的孔壁124上形成若干环绕该容置孔123的环形的凹槽125，每一凹槽125的两侧分别形成一相对凹槽125凸起的环形的凸缘126。 The fan frame 12 includes opposite side walls 121 . The middle part of the fan frame 12 is provided with a receiving hole 123 with an elliptical cross section passing through the two side walls 121 . The impeller 14 is installed in the receiving hole 123 . The fan frame 12 forms a plurality of annular grooves 125 surrounding the accommodation hole 123 on the hole wall 124 of the accommodation hole 123, and two sides of each groove 125 respectively form an annular groove 125 protruding. Flange 126.
风扇10工作时，叶轮14转动使风流由容置孔123的一侧进入容置孔123后由容置孔123的另一侧吹出。由于容置孔123的孔壁124上形成相间隔的凹槽125与凸缘126，凹槽125与凸缘126对经叶轮14旋转带动而流经容置孔123的气流形成加压，使气流向容置孔123外吹出的同时向中部集中，从而使得风扇10吹出的风流的风量更大，风压更强，可吹向更远处，散热效果更好。 When the fan 10 is working, the impeller 14 rotates so that the wind enters the accommodating hole 123 from one side of the accommodating hole 123 and blows out from the other side of the accommodating hole 123 . Since spaced apart grooves 125 and flanges 126 are formed on the hole wall 124 of the accommodation hole 123, the grooves 125 and flanges 126 pressurize the airflow flowing through the accommodation hole 123 driven by the rotation of the impeller 14, so that the airflow While blowing out of the accommodation hole 123, it is concentrated in the middle, so that the airflow blown out by the fan 10 has a larger air volume and stronger wind pressure, and can be blown farther away, with better heat dissipation effect.
该风扇10的容置孔123的横截面呈椭圆形，可改善风切声，降低风扇10工作时的噪音。 The cross section of the accommodating hole 123 of the fan 10 is elliptical, which can improve the sound of wind cutting and reduce the noise of the fan 10 when it is working.
在本实施方式中，凹槽125与凸缘126的横截面均呈圆弧形。在其它实施方式中，凹槽125与凸缘126的横截面还可以是弧形或其它形状，凹槽125与凸缘126在容置孔123的孔壁124上共同形成波浪形的表面。 In this embodiment, the cross-sections of the groove 125 and the flange 126 are arc-shaped. In other embodiments, the cross section of the groove 125 and the flange 126 may also be arc-shaped or other shapes, and the groove 125 and the flange 126 jointly form a wave-shaped surface on the hole wall 124 of the accommodating hole 123 .
在其它实施方式中，该风扇10的容置孔123的孔壁124上可只设有一个凹槽125与一个邻近凹槽125的凸缘126，同样可实现给风流加压的作用，使气流向容置孔123外吹出的同时向中部集中。 In other embodiments, only one groove 125 and one flange 126 adjacent to the groove 125 may be provided on the hole wall 124 of the accommodating hole 123 of the fan 10, which can also realize the effect of pressurizing the air flow, so that the air flow While blowing out of the housing hole 123, it is concentrated in the middle.
