Description

風扇組件fan assembly

本發明係關於一種風扇組件，特別係關於一種包含降噪環形凸板的風扇組件。The present invention relates to a fan assembly, and in particular to a fan assembly including a noise-reducing annular convex plate.

由於顯示卡在運作時會產生大量的熱，因此顯示卡通常會包含一或多個散熱風扇以有效地將顯示卡產生的熱逸散至外界。這樣的散熱風扇一般會透過風扇框設置於顯示卡的電路板。Since a graphics card generates a large amount of heat when operating, the graphics card usually includes one or more cooling fans to effectively dissipate the heat generated by the graphics card to the outside world. Such a cooling fan is generally installed on the circuit board of the display card through a fan frame.

然而，傳統的風扇框之氣流入口是與風扇框的外表面齊平。因此，散熱風扇所導引的散熱氣流難以流暢地進入氣流入口。如此一來，風扇組件的入風量及出風量會減少，而需要透過提高風扇的轉速來提升風扇的入風量及出風量，這增加了風扇產生的噪音。However, the air inlet of the traditional fan frame is flush with the outer surface of the fan frame. Therefore, it is difficult for the cooling airflow guided by the cooling fan to smoothly enter the airflow inlet. As a result, the air inlet volume and air outlet volume of the fan assembly will be reduced, and the fan speed needs to be increased to increase the fan air inlet volume and air outlet volume, which increases the noise generated by the fan.

本發明在於提供一種風扇組件，以提升風扇組件的入風量及出風量，而能在降低風扇的轉速之同時維持所需的入風量及出風量，進而減少風扇產生的噪音。The present invention provides a fan assembly to increase the air inlet volume and air outlet volume of the fan assembly, and maintain the required air inlet volume and air outlet volume while reducing the fan speed, thereby reducing the noise generated by the fan.

本發明一實施例所揭露之風扇組件包含一風扇框以及一扇葉。風扇框包含一框體以及一降噪環形凸板並具有一氣流入口以及一氣流出口。降噪環形凸板凸出於框體的一側並與框體共同形成一氣流通道。氣流入口位於降噪環形凸板遠離框體的一側。氣流出口位於框體遠離降噪環形凸板的一側。氣流入口透過氣流通道連通於氣流出口。扇葉可轉動地設置於框體並位於氣流通道中。降噪環形凸板相對風扇框的凸出高度介於扇葉的整體軸向厚度之0.5倍至1倍之間。A fan assembly disclosed in an embodiment of the present invention includes a fan frame and a fan blade. The fan frame includes a frame and a noise-reducing annular convex plate and has an air inlet and an air outlet. The noise reduction annular convex plate protrudes from one side of the frame and forms an airflow channel together with the frame. The airflow inlet is located on the side of the noise reduction annular convex plate away from the frame. The airflow outlet is located on the side of the frame away from the noise-reducing annular convex plate. The air flow inlet is connected to the air flow outlet through the air flow channel. The fan blades are rotatably arranged on the frame and located in the air flow channel. The protruding height of the noise reduction annular convex plate relative to the fan frame is between 0.5 times and 1 times the overall axial thickness of the fan blade.

根據上述實施例所揭露之風扇組件，由於降噪環形凸板相對風扇框的凸出高度介於扇葉的整體軸向厚度之0.5倍至1倍之間，且氣流入口位於降噪環形凸板遠離框體的一側，因此風扇組件的入風量及出風量會增加。如此一來，便能在較低的風扇轉速之同時維持所需的入風量及出風量，進而減少風扇產生的噪音。According to the fan assembly disclosed in the above embodiment, the protruding height of the noise-reducing annular convex plate relative to the fan frame is between 0.5 times and 1 times the overall axial thickness of the fan blade, and the airflow inlet is located on the noise-reducing annular convex plate. The side away from the frame will increase the air inlet and outlet volume of the fan assembly. In this way, the required air inlet and outlet volumes can be maintained at a lower fan speed, thereby reducing the noise generated by the fan.

於本實施例中，風扇框100包含一框體110、一降噪環形凸板120、一導流環形凸板130以及多個氣流導引結構140，並具有一氣流入口101、一氣流出口102以及一氣流通道103。In this embodiment, the fan frame 100 includes a frame 110, a noise reduction annular convex plate 120, a guide annular convex plate 130 and a plurality of airflow guide structures 140, and has an airflow inlet 101 and an airflow outlet 102. and an airflow channel 103.

框體110具有彼此背對的一第一表面111以及一第二表面112。降噪環形凸板120例如呈圓環狀且凸出於第一表面111。導流環形凸板130例如呈圓環狀且凸出於第二表面112。降噪環形凸板120、框體110以及導流環形凸板130共同形成氣流通道103。氣流入口101位於降噪環形凸板120遠離框體110的一側。氣流出口102位於導流環形凸板130遠離框體110的一側。氣流入口101透過氣流通道103連通於氣流出口102。於本實施例中，降噪環形凸板120具有位於氣流入口101的一圓弧導角121。也就是說，降噪環形凸板120中遠離框體110的端面呈圓弧狀並朝框體110漸縮。此外，於本實施例中，降噪環形凸板120相對框體110的第一表面111之凸出高度H例如介於5毫米(mm)至15毫米(mm)。於本實施例中，導流環形凸板130具有一導流邊緣131。導流邊緣131位於氣流通道103。氣流導引結構140彼此分離且從導流邊緣131朝氣流通道103凸出。於本實施例中，氣流導引結構140的數量例如為32個。於本實施例中，導流邊緣131從遠離氣流出口102的一側漸擴至靠近氣流出口102的一側，但並不以此為限。於其他實施例中，只要導流邊緣靠近氣流出口的一側之直徑大於導流邊緣遠離氣流出口的一側之直徑，導流邊緣靠近氣流出口的一側以及導流邊緣遠離氣流出口的一側之間亦可形成段差而非漸擴的外形。The frame 110 has a first surface 111 and a second surface 112 facing away from each other. The noise reduction annular protruding plate 120 is, for example, annular and protrudes from the first surface 111 . The flow guide annular convex plate 130 is, for example, annular and protrudes from the second surface 112 . The noise reduction annular convex plate 120 , the frame 110 and the air guide annular convex plate 130 jointly form an airflow channel 103 . The airflow inlet 101 is located on the side of the noise reduction annular convex plate 120 away from the frame 110 . The airflow outlet 102 is located on the side of the guide annular convex plate 130 away from the frame 110 . The airflow inlet 101 is connected to the airflow outlet 102 through the airflow channel 103 . In this embodiment, the noise-reducing annular convex plate 120 has an arc guide 121 located at the airflow inlet 101 . That is to say, the end surface of the noise reduction annular convex plate 120 away from the frame 110 is arc-shaped and tapers toward the frame 110 . In addition, in this embodiment, the protruding height H of the noise reduction annular protruding plate 120 relative to the first surface 111 of the frame 110 is, for example, between 5 millimeters (mm) and 15 millimeters (mm). In this embodiment, the flow guiding annular convex plate 130 has a flow guiding edge 131 . The flow guide edge 131 is located in the airflow channel 103 . The airflow guide structures 140 are separated from each other and protrude from the airflow guide edge 131 toward the airflow channel 103 . In this embodiment, the number of airflow guiding structures 140 is, for example, 32. In this embodiment, the flow guide edge 131 gradually expands from the side away from the air flow outlet 102 to the side close to the air flow outlet 102, but it is not limited to this. In other embodiments, as long as the diameter of the side of the guide edge close to the air flow outlet is larger than the diameter of the side of the guide edge away from the air flow outlet, the side of the guide edge close to the air flow outlet and the side of the guide edge away from the air flow outlet A step difference can also be formed instead of a gradually expanding shape.

轉動組件200設置於框體110。於本實施例中，扇葉300位於氣流通道103中並包含一輪轂310、多個葉片320以及多個環形連接件330。葉片320徑向地凸出於輪轂310。這些環形連接件330分別將相鄰的兩個葉片320遠離輪轂310的一側連接起來。輪轂310透過轉動組件200可轉動地設置於框體110。The rotating component 200 is provided on the frame 110 . In this embodiment, the fan blade 300 is located in the airflow channel 103 and includes a hub 310 , a plurality of blades 320 and a plurality of annular connectors 330 . Blades 320 project radially from hub 310 . These annular connectors 330 respectively connect the sides of two adjacent blades 320 away from the hub 310 . The hub 310 is rotatably disposed on the frame 110 through the rotating assembly 200 .

須注意的是，於其他實施例中，扇葉亦可僅包含一個環形連接件，於這樣的實施例中，此環形連接件將扇葉的所有葉片遠離輪轂的一側連接起來。於再其他實施例中，扇葉亦可無需包含環形連接件，而使得這些葉片遠離輪轂的一側彼此分離。It should be noted that in other embodiments, the fan blade may also include only one annular connector. In such an embodiment, the annular connector connects all the blades of the fan blade on the side away from the hub. In still other embodiments, the fan blades do not need to include an annular connector, so that the sides of the blades away from the hub are separated from each other.

於本實施例中，降噪環形凸板120相對框體110的凸出高度H介於扇葉300的整體軸向厚度T1之0.5倍至1倍之間。也就是說，降噪環形凸板120相對框體110的凸出高度H為扇葉300的整體軸向厚度T1之0.5倍以上以及扇葉300的整體軸向厚度T1之1倍以下。具體來說，於本實施例中，降噪環形凸板120相對框體110的凸出高度H例如為扇葉300的整體軸向厚度T1之二分之一。In this embodiment, the protruding height H of the noise reduction annular convex plate 120 relative to the frame 110 is between 0.5 times and 1 times the overall axial thickness T1 of the fan blade 300 . That is to say, the protruding height H of the noise reduction annular convex plate 120 relative to the frame 110 is more than 0.5 times the overall axial thickness T1 of the fan blade 300 and less than 1 time the overall axial thickness T1 of the fan blade 300 . Specifically, in this embodiment, the protruding height H of the noise reduction annular convex plate 120 relative to the frame 110 is, for example, one-half of the overall axial thickness T1 of the fan blade 300 .

須注意的是，於本實施例中，輪轂310之軸向厚度T2相同於葉片320的軸向厚度T3。因此，於本實施例中，扇葉300的整體軸向厚度T1等於輪轂310之軸向厚度T2且等於葉片320的軸向厚度T3，但並不以此為限。於其他實施例中，葉片的整體軸向厚度亦可大於輪轂的整體軸向厚度，在這樣的實施例中，扇葉的整體軸向厚度係等於葉片的整體軸向厚度。或者，於再其他實施例中，輪轂的整體軸向厚度亦可大於葉片的整體軸向厚度，在這樣的實施例中，扇葉的整體軸向厚度係等於輪轂的整體軸向厚度。It should be noted that in this embodiment, the axial thickness T2 of the hub 310 is the same as the axial thickness T3 of the blade 320 . Therefore, in this embodiment, the overall axial thickness T1 of the fan blade 300 is equal to the axial thickness T2 of the hub 310 and equal to the axial thickness T3 of the blade 320, but is not limited to this. In other embodiments, the overall axial thickness of the blade may also be greater than the overall axial thickness of the hub. In such an embodiment, the overall axial thickness of the fan blade is equal to the overall axial thickness of the blade. Alternatively, in other embodiments, the overall axial thickness of the hub may be greater than the overall axial thickness of the blades. In such an embodiment, the overall axial thickness of the blades is equal to the overall axial thickness of the hub.

此外，於本實施例中，輪轂310的軸向厚度T2例如介於10 mm至10.2 mm之間。於本實施例中，扇葉300與框體110之間有一間隔距離G，間隔距離G例如介於3 mm至3.5 mm之間。In addition, in this embodiment, the axial thickness T2 of the hub 310 is, for example, between 10 mm and 10.2 mm. In this embodiment, there is a separation distance G between the fan blade 300 and the frame 110. The separation distance G is, for example, between 3 mm and 3.5 mm.

須注意的是，根據本發明的降噪環形凸板並不限於包含位於氣流入口的圓弧導角。請參閱圖4，圖4為根據本發明第二實施例的風扇組件之側剖示意圖的局部放大圖。須注意的是，本實施例的風扇組件10a與圖1至圖3中的風扇組件10之差異僅在於本實施例的風扇組件10a之風扇框100a的降噪環形凸板120a係包含位於氣流入口101a的導斜角122a而非圖3中根據第一實施例的圓弧導角121。也就是說，於本實施例中，降噪環形凸板120a中遠離框體110a的端面呈傾斜狀並朝框體110a漸縮。此外，本實施例的風扇組件10a之風扇框100a的其他部分與圖1至圖3中的風扇組件10的風扇框100相同，且本實施例的風扇組件10a亦可包含圖1至圖3中的轉動組件200以及扇葉300，故不再贅述。It should be noted that the noise-reducing annular convex plate according to the present invention is not limited to including an arc-shaped leading angle located at the airflow inlet. Please refer to FIG. 4 , which is a partially enlarged side view of a fan assembly according to a second embodiment of the present invention. It should be noted that the difference between the fan assembly 10a of this embodiment and the fan assembly 10 in FIGS. 1 to 3 is only that the noise-reducing annular convex plate 120a of the fan frame 100a of the fan assembly 10a of this embodiment includes an annular protrusion located at the airflow inlet. The lead angle 122a of 101a is not the arc lead angle 121 according to the first embodiment in FIG. 3 . That is to say, in this embodiment, the end surface of the noise reduction annular convex plate 120a away from the frame 110a is inclined and tapered toward the frame 110a. In addition, other parts of the fan frame 100a of the fan assembly 10a of this embodiment are the same as the fan frame 100 of the fan assembly 10 in FIGS. 1 to 3 , and the fan assembly 10a of this embodiment may also include those in FIGS. 1 to 3 The rotating assembly 200 and the fan blade 300 are not described again.

須注意的是，於其他實施例中，風扇組件之風扇框亦可無需包含導流環形凸板130以及氣流導引結構140。It should be noted that in other embodiments, the fan frame of the fan assembly does not need to include the guide annular convex plate 130 and the airflow guide structure 140 .

此外，經發明人反覆實驗，習知技術中風扇框之氣流入口與風扇框之外表面齊平且沒有在氣流入口形成圓弧導角或導斜角之風扇組件在產生26加權分貝(dBA)之情況中，出風量為87.8立方英尺/分(cfm)，靜壓為1.11毫米水柱(mmH 2O)，扇葉轉速為2050每分鐘轉速(RPM)；在圖1中的根據本發明第一實施例之風扇組件10產生26加權分貝(dBA)之情況中，出風量為118立方英尺/分(cfm)，靜壓為1.4毫米水柱(mmH 2O)，扇葉轉速為2200每分鐘轉速(RPM)；在圖4中根據本發明第二實施例的風扇組件10a產生26加權分貝(dBA)之情況中，出風量為104.8立方英尺/分(cfm)，靜壓為1.39毫米水柱(mmH 2O)，扇葉轉速為2200每分鐘轉速(RPM)。由以上數據得之，根據本發明的降噪環形凸板之設置以及圓弧導角或導斜角之形成使得風扇組件的出風量增加而能在產生相同噪音之情況下有更高的轉速。也就是說，風扇組件得以透過更低的轉速運轉達到特定的出風量需求，而能產生較小的噪音。 In addition, after repeated experiments by the inventor, the fan assembly in the conventional technology, in which the airflow inlet of the fan frame is flush with the outer surface of the fan frame and does not form an arc leading angle or a leading angle at the airflow inlet, generates 26 weighted decibels (dBA). In the case of In the case where the fan assembly 10 of the embodiment generates 26 weighted decibels (dBA), the air outlet volume is 118 cubic feet per minute (cfm), the static pressure is 1.4 millimeters of water column (mmH 2 O), and the fan blade rotation speed is 2200 rpm ( RPM); in the case where the fan assembly 10a according to the second embodiment of the present invention generates 26 weighted decibels (dBA) in Figure 4, the air outlet volume is 104.8 cubic feet per minute (cfm) and the static pressure is 1.39 millimeters of water column (mmH 2 O), the fan blade speed is 2200 revolutions per minute (RPM). From the above data, it can be concluded that the arrangement of the noise-reducing annular convex plate and the formation of the arc guide angle or the guide angle according to the present invention increase the air output of the fan assembly and enable it to have a higher rotation speed while generating the same noise. That is to say, the fan assembly can achieve a specific air volume requirement by running at a lower speed and produce less noise.

根據上述實施例所揭露之風扇組件，由於降噪環形凸板相對風扇框的凸出高度介於扇葉的整體軸向厚度之0.5倍至1倍之間，且氣流入口位於降噪環形凸板遠離框體的一側，因此風扇組件的入風量及出風量會增加。如此一來，便能在較低的風扇轉速之同時維持所需的入風量及出風量，進而減少風扇產生的噪音。According to the fan assembly disclosed in the above embodiment, the protruding height of the noise-reducing annular convex plate relative to the fan frame is between 0.5 times and 1 times the overall axial thickness of the fan blade, and the airflow inlet is located on the noise-reducing annular convex plate. The side away from the frame will increase the air inlet and outlet volume of the fan assembly. In this way, the required air inlet and outlet volumes can be maintained at a lower fan speed, thereby reducing the noise generated by the fan.

雖然本發明以前述之諸項實施例揭露如上，然其並非用以限定本發明，任何熟習相像技藝者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，因此本發明之專利保護範圍須視本說明書所附之申請專利範圍所界定者為準。Although the present invention has been disclosed in the foregoing embodiments, they are not intended to limit the present invention.
