Description

風扇fan

本發明係關於一種風扇。The present invention relates to a fan.

請參照圖1，習知的風扇80通常包括一扇框81與一收容於扇框81內的葉輪83。扇框81的中部為一橫截面呈圓形的用以收容葉輪83的內壁光滑的容置孔85。葉輪83轉動，氣流從容置孔85的一側進入容置孔85後經葉輪83作用由容置孔85的另一側向四周發散地吹出。對於需要風流集中散熱的元件，此風扇80的散熱效果並不好。Referring to FIG. 1 , the conventional fan 80 generally includes a frame 81 and an impeller 83 received in the frame 81 . The middle portion of the frame 81 is a circular receiving hole 85 having a circular cross section for receiving the inner wall of the impeller 83. The impeller 83 rotates, and the airflow enters the accommodating hole 85 from one side of the accommodating hole 85, and is blown out by the impeller 83 from the other side of the accommodating hole 85 to the periphery. For components that require concentrated heat dissipation from the wind, the heat dissipation of the fan 80 is not good.

鑒於以上，有必要提供一種使風流更為集中吹出的風扇。In view of the above, it is necessary to provide a fan that blows the wind more concentratedly.

一種風扇，包括一扇框及一葉輪，該扇框的中部設有一容置孔，該葉輪裝設於該容置孔內，該扇框於該容置孔的孔壁上形成環繞該容置孔的一環形的凹槽及一鄰近凹槽並相對該凹槽凸起的環形的凸緣。A fan includes a frame and an impeller. The middle of the fan frame is provided with a receiving hole. The fan is mounted in the receiving hole, and the fan frame is formed around the hole of the receiving hole. An annular groove of the bore and an annular flange adjacent the recess and projecting relative to the recess.

一種風扇，包括一扇框及一葉輪，該扇框的中部設有一容置孔，該葉輪裝設於該容置孔內，該扇框於該容置孔的孔壁上形成複數環繞該容置孔的環形的凹槽，每一凹槽之兩側分別形成一相對凹槽凸起的環形的凸緣。A fan includes a frame and an impeller. The middle of the fan frame is provided with a receiving hole. The fan is mounted in the receiving hole, and the fan frame forms a plurality of surrounding holes on the hole wall of the receiving hole. The annular grooves of the holes are formed, and the two sides of each groove respectively form an annular flange which is convex with respect to the groove.

該風扇的凹槽與凸緣對經葉輪旋轉帶動而流經容置孔的氣流加壓，使氣流向容置孔外吹出的同時向中部集中，從而使得風扇吹出的風流的風量更大，風壓更強，可吹向更遠處，散熱效果更好。The groove and the flange of the fan pressurize the airflow flowing through the accommodating hole by the rotation of the impeller, so that the airflow is concentrated toward the middle while being blown out of the accommodating hole, so that the airflow of the fan blows out is larger, and the wind The pressure is stronger, it can be blown farther, and the heat dissipation effect is better.

圖1是習知風扇於工作狀態的平面示意圖。1 is a schematic plan view of a conventional fan in an operating state.

圖2是本發明風扇的較佳實施方式的立體圖。Figure 2 is a perspective view of a preferred embodiment of the fan of the present invention.

圖3是圖2中的風扇於工作狀態的平面示意圖。Figure 3 is a plan view showing the fan of Figure 2 in an operating state.

請參照圖2與圖3，本發明風扇10的較佳實施方式，包括一扇框12及一葉輪14。Referring to FIG. 2 and FIG. 3, a preferred embodiment of the fan 10 of the present invention includes a frame 12 and an impeller 14.

該扇框12包括相對的兩側壁121。該扇框12的中部設有一橫截面呈橢圓形的貫穿該兩側壁121的容置孔123。該葉輪14裝設於該容置孔123內。該扇框12於該容置孔123的孔壁124上形成複數環繞該容置孔123的環形的凹槽125，每一凹槽125之兩側分別形成一相對凹槽125凸起的環形的凸緣126。The fan frame 12 includes opposite side walls 121. The middle portion of the fan frame 12 is provided with a receiving hole 123 extending through the two side walls 121 in an elliptical cross section. The impeller 14 is mounted in the receiving hole 123. An annular groove 125 surrounding the accommodating hole 123 is formed on the hole wall 124 of the accommodating hole 123. The two sides of each groove 125 respectively form a ring-shaped concave groove corresponding to the groove 125. Flange 126.

風扇10工作時，葉輪14轉動使風流由容置孔123的一側進入容置孔123後由容置孔123的另一側吹出。由於容置孔123的孔壁124上形成相間隔的凹槽125與凸緣126，凹槽125與凸緣126對經葉輪14旋轉帶動而流經容置孔123的氣流形成加壓，使氣流向容置孔123外吹出的同時向中部集中，從而使得風扇10吹出的風流的風量更大，風壓更強，可吹向更遠處，散熱效果更好。When the fan 10 is in operation, the impeller 14 is rotated to allow the airflow to enter the accommodating hole 123 from one side of the accommodating hole 123 and then blown out from the other side of the accommodating hole 123. Since the groove wall 125 and the flange 126 are formed on the hole wall 124 of the accommodating hole 123, the groove 125 and the flange 126 pressurize the airflow flowing through the accommodating hole 123 through the impeller 14 to make the air flow. When the outside of the accommodating hole 123 is blown out, it is concentrated toward the center, so that the airflow blown by the fan 10 has a larger air volume, the wind pressure is stronger, and it can be blown farther, and the heat dissipation effect is better.

該風扇10的容置孔123的橫截面呈橢圓形，可改善風切聲，降低風扇10工作時的噪音。The receiving hole 123 of the fan 10 has an elliptical cross section, which can improve the wind cutting sound and reduce the noise of the fan 10 during operation.

在本實施方式中，凹槽125與凸緣126的橫截面均呈圓弧形。在其他實施方式中，凹槽125與凸緣126的橫截面還可以是弧形或其他形狀，凹槽125與凸緣126在容置孔123的孔壁124上共同形成波浪形的表面。In the present embodiment, the groove 125 and the flange 126 have a circular arc shape in cross section. In other embodiments, the cross-section of the recess 125 and the flange 126 may also be curved or otherwise shaped, and the recess 125 and the flange 126 together form a wavy surface on the bore wall 124 of the receiving aperture 123.

在其他實施方式中，該風扇10的容置孔123的孔壁124上可只設有一個凹槽125與一個凸緣126，同樣可實現給風流加壓的作用，使氣流向容置孔123外吹出的同時向中部集中。In other embodiments, the hole wall 124 of the accommodating hole 123 of the fan 10 can be provided with only one groove 125 and one flange 126, and the air flow can be pressurized to make the air flow toward the accommodating hole 123. The outside is blown out while being concentrated in the middle.

綜上所述，本發明確已符合發明專利之要件，遂依法提出專利申請。惟，以上所述者僅為本發明之較佳實施方式，自不能以此限制本案之申請專利範圍。舉凡熟悉本案技藝之人士爰依本發明之精神所作之等效修飾或變化，皆應涵蓋於以下申請專利範圍內。In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
