Description
本案是關於散熱技術，特別是一具高散熱效能且低噪音的風扇裝置及電子裝置。This case is about heat dissipation technology, especially a fan device and electronic device with high heat dissipation performance and low noise.
近年來，電子產業蓬勃發展，各式電子產品逐漸充斥於大眾之日常生活中。隨著大眾對於電子產品的高效能之追求攀高，電子產品中之各類電子元件的發熱與散熱問題也愈顯重要。為了協助散熱，於電子產品中通常會配備有風扇裝置以對其內部電子元件所產生的高熱進行散熱。In recent years, the electronics industry has flourished, and various electronic products have gradually filled the daily life of the public. As the public's pursuit of high performance in electronic products climbs, the heat and heat dissipation of various electronic components in electronic products is becoming more and more important. In order to assist in heat dissipation, a fan device is usually provided in an electronic product to dissipate heat generated by its internal electronic components.
一般而言，風扇裝置根據氣流出風方向而可大致區分成軸流式風扇裝置與離心式風扇裝置。其中，軸流式風扇裝置的氣流出風方向垂直於其葉片旋轉面，而離心式風扇裝置的氣流出風方向則平行於其葉片旋轉面。傳統上，由於電子產品的輕薄化設計，軸流式風扇裝置因不適用於此，而多半採用離心式風扇裝置作為電子產品的散熱機制。然而，傳統之離心式風扇裝置所能提供的流量較小，致使其散熱效率低下。In general, the fan device can be roughly classified into an axial fan device and a centrifugal fan device according to the airflow direction. Wherein, the airflow direction of the axial flow fan device is perpendicular to the rotation surface of the blade, and the airflow direction of the centrifugal fan device is parallel to the rotation surface of the blade. Traditionally, due to the thin and light design of electronic products, axial flow fan devices are not suitable for this, and most of them use centrifugal fan devices as the heat dissipation mechanism of electronic products. However, the conventional centrifugal fan unit can provide a small flow rate, resulting in low heat dissipation efficiency.

The fan device 100 can be used to dissipate heat generated by internal electronic components of the electronic device 200 , thereby improving the operational performance of the electronic device 200 .
電子裝置200包含主體210。風扇裝置100可容置於主體210之中。風扇裝置100包含框體110、離心式風扇120以及軸流式風扇130。其中，離心式風扇120與軸流式風扇130可轉動地設置於框體110中。The electronic device 200 includes a body 210. The fan device 100 can be housed in the body 210. The fan device 100 includes a housing 110, a centrifugal fan 120, and an axial fan 130. The centrifugal fan 120 and the axial fan 130 are rotatably disposed in the casing 110.
框體110可用以容置離心式風扇120與軸流式風扇130。框體110具有軸向入風口H1。軸流式風扇130位於離心式風扇120的軸向上。並且，軸流式風扇130之局部可從軸向入風口H1中突出於框體110，以導引進更多的氣流。The frame 110 can be used to accommodate the centrifugal fan 120 and the axial fan 130. The frame body 110 has an axial air inlet H1. The axial fan 130 is located in the axial direction of the centrifugal fan 120. Moreover, a part of the axial fan 130 can protrude from the axial air inlet H1 to the frame 110 to introduce more airflow.
於此，軸流式風扇130可輸出較大的氣體流量，故本案藉由將軸流式風扇130設置於離心式風扇120之軸向上來協助增加離心式風扇120的進氣量，以使得經由離心式風扇120輸出的氣體流量可因此增加，進而致使風扇裝置100整體的散熱效能可獲得提升。Here, the axial flow fan 130 can output a large gas flow rate, so the present embodiment assists in increasing the intake air amount of the centrifugal fan 120 by arranging the axial flow fan 130 in the axial direction of the centrifugal fan 120 so that The flow rate of the gas output by the centrifugal fan 120 can be increased, thereby causing an increase in the heat dissipation performance of the fan device 100 as a whole.
在一實施例中，框體110可包含上殼體111、下殼體112與側框體113。上殼體111和下殼體112彼此相對。上殼體111和下殼體112概呈片狀。上殼體111之邊緣可抵靠於側框體113之內周緣，且下殼體112之邊緣可抵靠於側框體113之內周緣。並且，側框體113可和上殼體111與下殼體112共同形成一容置空間。於此，側框體113實質上垂直於上殼體111與下殼體112。In an embodiment, the frame 110 may include an upper casing 111, a lower casing 112, and a side casing 113. The upper case 111 and the lower case 112 are opposed to each other. The upper case 111 and the lower case 112 are substantially in the form of a sheet. The edge of the upper casing 111 can abut against the inner circumference of the side frame body 113, and the edge of the lower casing 112 can abut against the inner circumference of the side frame body 113. Moreover, the side frame 113 can form an accommodation space together with the upper casing 111 and the lower casing 112. Here, the side frame body 113 is substantially perpendicular to the upper case 111 and the lower case 112.
離心式風扇120可用以使得經由其排出的氣體流向和其中心軸呈現垂直。在一實施例中，離心式風扇120可包含扇轂121以及複數扇葉122。扇轂121可呈圓凸塊狀。複數扇葉122間隔地設置在扇轂121的周緣，並沿著扇轂121的徑向向外延伸。於此，各扇葉122概呈片狀。The centrifugal fan 120 can be used such that the flow of gas discharged therethrough is perpendicular to its central axis. In an embodiment, the centrifugal fan 120 can include a hub 121 and a plurality of blades 122. The hub 121 may have a circular convex shape. The plurality of blades 122 are disposed at intervals around the circumference of the hub 121 and extend outward in the radial direction of the hub 121. Here, each of the blades 122 has a sheet shape.
在一實施例中，各扇葉122可包含第一翼部1221與第二翼部1222。其中，第一翼部1221之一端連接於扇轂121的周緣，且第一翼部1221之另一端連接於第二翼部1222。In an embodiment, each of the blades 122 may include a first wing portion 1221 and a second wing portion 1222. The one end of the first wing portion 1221 is connected to the periphery of the hub 121, and the other end of the first wing portion 1221 is connected to the second wing portion 1222.
在一些實施態樣中，於側向觀看離心式風扇120之各扇葉122時，第二翼部1222之頂面B2可高於第一翼部1221之頂面B1。此外，第二翼部1222之底面C2可低於第一翼部1221之底面C1。換言之，此時離心式風扇120之各扇葉122的寬度從第二翼部1222往第一翼部1221之方向是逐漸變窄，如圖7所示。但本案並非以此為限，在另一些實施態樣中，離心式風扇120之各扇葉122的寬度從第二翼部1222往第一翼部1221之方向翼可維持等寬，換言之，此時第二翼部1222之頂面B2可和第一翼部1221之頂面B1等高，且第二翼部1222之底面C2可和第一翼部1221之底面C1等低。In some embodiments, when the blades 122 of the centrifugal fan 120 are viewed laterally, the top surface B2 of the second wing portion 1222 may be higher than the top surface B1 of the first wing portion 1221. In addition, the bottom surface C2 of the second wing portion 1222 may be lower than the bottom surface C1 of the first wing portion 1221. In other words, at this time, the width of each of the blades 122 of the centrifugal fan 120 is gradually narrowed from the second wing portion 1222 toward the first wing portion 1221, as shown in FIG. However, the present invention is not limited thereto. In other implementations, the width of each of the blades 122 of the centrifugal fan 120 may be equal in width from the second wing portion 1222 to the first wing portion 1221, in other words, The top surface B2 of the second wing portion 1222 may be equal to the top surface B1 of the first wing portion 1221, and the bottom surface C2 of the second wing portion 1222 may be lower than the bottom surface C1 of the first wing portion 1221.
在一實施例中，離心式風扇120可更包含環狀件123。環狀件123環接於每一個扇葉122的第二翼部1222，以降低因風阻壓力過大而產生的振動，並可有效減輕噪音與風切聲。於此，環狀件123是環接在各第二翼部1222的頂面B2處，且環狀件123的頂面B3可和第二翼部1222的頂面B2一樣高，以不突出於第二翼部1222之頂面B2方式來形成流線型設計，如圖7所示。In an embodiment, the centrifugal fan 120 may further include a ring member 123. The ring member 123 is looped around the second wing portion 1222 of each of the blades 122 to reduce vibration caused by excessive wind pressure and to effectively reduce noise and wind cut. Here, the ring member 123 is looped at the top surface B2 of each of the second wing portions 1222, and the top surface B3 of the ring member 123 can be as high as the top surface B2 of the second wing portion 1222 so as not to protrude from The top surface B2 of the second wing portion 1222 is formed in a streamlined design as shown in FIG.
圖8為氣流動力圖之一實施例的示意圖。請參閱圖1至圖8，在一些實施態樣中，離心式風扇120之扇葉122的攻角α可介於10度至30度之間，以導引氣流進入扇葉122。其中，所述之攻角α是指扇葉122的弦線（chord line）V1與氣流之流場向量V2的相對角度。在一些實施態樣中，離心式風扇120之扇葉122的攻角α為20度時，其導引效果較好。Figure 8 is a schematic illustration of one embodiment of an airflow dynamic diagram. Referring to FIGS. 1-8 , in some embodiments, the angle of attack α of the fan blades 122 of the centrifugal fan 120 may be between 10 degrees and 30 degrees to direct airflow into the fan blades 122 . The angle of attack α refers to the relative angle of the chord line V1 of the blade 122 and the flow field vector V2 of the airflow. In some embodiments, when the angle of attack α of the fan blade 122 of the centrifugal fan 120 is 20 degrees, the guiding effect is better.
在一些實施態樣中，離心式風扇120的扇轂121、扇葉122及環狀件123可以是利用一體成形之方式製成。In some embodiments, the hub 121, the fan blades 122, and the ring member 123 of the centrifugal fan 120 may be formed by integral molding.
軸流式風扇130可使得經由其排出的氣體流向和其中心軸呈現平行。在一實施例中，軸流式風扇130可包含扇轂131和複數扇葉132。扇轂131可呈圓凸塊狀。複數扇葉132間隔地設置在扇轂131的周緣，並沿著扇轂131的徑向向外延伸。各扇葉132概呈片狀。並且，各扇葉132具有完整的流線設計，因而可避免傳統上的撞風面噪音與紊流的產生。The axial fan 130 may cause the flow of gas discharged therethrough to be parallel to its central axis. In an embodiment, the axial fan 130 can include a hub 131 and a plurality of blades 132. The hub 131 may have a circular convex shape. The plurality of blades 132 are disposed at intervals around the circumference of the hub 131 and extend outward in the radial direction of the hub 131. Each of the blades 132 has a sheet shape. Moreover, each of the blades 132 has a complete streamline design, thereby avoiding the occurrence of conventional windsurfing noise and turbulence.
在一些實施態樣中，軸流式風扇130之扇葉132的數量可少於離心式風扇120之扇葉122的數量。In some implementations, the number of blades 132 of the axial fan 130 can be less than the number of blades 122 of the centrifugal fan 120.
在一些實施態樣中，軸流式風扇130的扇轂131及扇葉132可以是利用一體成形之方式製成。In some embodiments, the hub 131 and the fan blades 132 of the axial fan 130 may be formed by integral molding.
在一實施例中，風扇裝置100可更包含驅動組140。驅動組140設置於下殼體112上並位於容置空間中。驅動組140連接於離心式風扇120與軸流式風扇130，且驅動組140可用以驅動離心式風扇120與軸流式風扇130進行轉動。In an embodiment, the fan device 100 may further include a drive group 140. The driving group 140 is disposed on the lower casing 112 and located in the accommodating space. The driving group 140 is connected to the centrifugal fan 120 and the axial fan 130, and the driving group 140 can be used to drive the centrifugal fan 120 and the axial fan 130 to rotate.
在一實施例中，驅動組140可具有一轉軸141。離心式風扇120與軸流式風扇130分別連接於轉軸141，且驅動組140可透過驅動轉軸141進行運轉來帶動離心式風扇120與軸流式風扇130一起進行轉動。In an embodiment, the drive group 140 can have a shaft 141. The centrifugal fan 120 and the axial fan 130 are respectively connected to the rotating shaft 141, and the driving group 140 can be operated by the driving rotating shaft 141 to drive the centrifugal fan 120 to rotate together with the axial fan 130.
在一實施例中，轉軸141可呈凸柱狀。此時，離心式風扇120可對應於轉軸141於扇轂121上設置一套接孔124，且軸流式風扇130可對應於轉軸141於扇轂131上設置一嵌入孔（圖未示），如圖3所示。其中，套接孔124是貫穿於扇轂121之相對二端面。於此，轉軸141之端部於穿過離心式風扇120的套接孔124後可嵌入於軸流式風扇130的嵌入孔中，以藉此將離心式風扇120與軸流式風扇130依序結合於驅動組140上，但本案並非以此為限。In an embodiment, the rotating shaft 141 may have a convex column shape. At this time, the centrifugal fan 120 may be provided with a set of holes 124 corresponding to the rotating shaft 141 on the hub 121, and the axial fan 130 may be provided with an insertion hole (not shown) corresponding to the rotating shaft 141 on the hub 131. As shown in Figure 3. The socket holes 124 are formed through opposite end faces of the hub 121. Herein, the end of the rotating shaft 141 can be embedded in the insertion hole of the axial fan 130 after passing through the socket hole 124 of the centrifugal fan 120, thereby sequentially displacing the centrifugal fan 120 and the axial fan 130. It is combined with the drive group 140, but the present invention is not limited thereto.
在另一實施態樣中，轉軸141亦可呈凹柱狀，例如凹設一嵌入孔142。此時，離心式風扇120可對應於轉軸141於扇轂121上設置一套接孔124，且軸流式風扇130可對應於轉軸141於扇轂131上設置一連接柱133，如圖5所示。於此，軸流式風扇130的連接柱133於穿過離心式風扇120的套接孔124後可嵌入於嵌入孔142中，以藉此將離心式風扇120與軸流式風扇130依序結合於驅動組140上。In another embodiment, the rotating shaft 141 may also have a concave column shape, for example, an insertion hole 142 is recessed. At this time, the centrifugal fan 120 may be provided with a set of connecting holes 124 on the hub 121 corresponding to the rotating shaft 141, and the axial flow fan 130 may be provided with a connecting post 133 on the hub 131 corresponding to the rotating shaft 141, as shown in FIG. Show. Here, the connecting post 133 of the axial fan 130 can be embedded in the insertion hole 142 after passing through the socket hole 124 of the centrifugal fan 120, thereby sequentially combining the centrifugal fan 120 and the axial fan 130. On the drive group 140.
在一些實施例中，軸流式風扇120和離心式風扇130可以是利用一體成形之方式製成。舉例而言，利用兩種材質以模內射出（insert molding）方式一體成形製出。但本案並非以此為限，在另一些實施例中，軸流式風扇120和離心式風扇130亦可分別利用模具射出後，再依定位做膠合。In some embodiments, the axial fan 120 and the centrifugal fan 130 may be fabricated in one piece. For example, two materials are integrally formed by insert molding. However, the present invention is not limited thereto. In other embodiments, the axial fan 120 and the centrifugal fan 130 may also be respectively molded by using a mold, and then glued according to the positioning.
在一實施例中，軸向入風口H1可開設於上殼體111。軸向入風口H1概呈圓形。於此，軸向入風口H1於下殼體112的正向投影可大於軸流式風扇130於下殼體112的正向投影，且小於離心式風扇120於下殼體112的正向投影。換言之，以俯視角度朝第一殼體111之方向觀看風扇裝置100時，可從軸向入風口H1所裸露出的範圍中觀看到軸流式風扇130的整個扇葉132，且離心式風扇120的扇葉122會有局部遮擋於第一殼體111之下。In an embodiment, the axial air inlet H1 can be opened in the upper casing 111. The axial air inlet H1 is substantially circular. Here, the forward projection of the axial air inlet H1 in the lower casing 112 may be greater than the forward projection of the axial fan 130 in the lower casing 112 and smaller than the forward projection of the centrifugal fan 120 in the lower casing 112. In other words, when the fan device 100 is viewed in the direction of the first housing 111 in a plan view, the entire blade 132 of the axial fan 130 can be viewed from the range exposed by the axial air inlet H1, and the centrifugal fan 120 is viewed. The fan blades 122 are partially obscured below the first housing 111.
在一實施例中，框體110可更具有一個入風區A1。入風區A1相對於軸向入風口H1開設於下殼體112。在一些實施態樣中，入風區A1可由多個，例如三個入風口H21-H23所組成。因此，當驅動組140驅動離心式風扇120與軸流式風扇130轉動時，氣流可從軸向入風口H1以及入風口H21-H23進入至框體110中。In an embodiment, the frame 110 may further have an air inlet area A1. The air inlet area A1 is opened in the lower casing 112 with respect to the axial air inlet H1. In some embodiments, the air inlet area A1 may be composed of a plurality of, for example, three air inlets H21-H23. Therefore, when the driving group 140 drives the centrifugal fan 120 and the axial fan 130 to rotate, the airflow can enter the casing 110 from the axial air inlet H1 and the air inlets H21-H23.
圖9為風扇裝置之流道之一實施例的示意圖。請參閱圖1至圖9，框體110可更具有一個徑向出風口H3，且徑向出風口H3開設側框體113上。徑向出風口H3可用以供氣流自此離開框體110。因此，當氣流從軸向入風口H1以及入風口H21-H23進入至框體110之容置空間後，可經由離心式風扇120之推動而沿著流道F1從徑向出風口H3流出框體110外，如圖9所示，於此移除框體110之上殼體111以顯示出位於框體110中之流道F1。Figure 9 is a schematic illustration of one embodiment of a flow path for a fan unit. Referring to FIG. 1 to FIG. 9 , the frame body 110 may further have a radial air outlet H3 , and the radial air outlet H3 opens on the side frame 113 . The radial air outlet H3 can be used to allow the air flow to leave the frame 110 from there. Therefore, when the airflow enters the accommodating space of the frame 110 from the axial air inlet H1 and the air inlet H21-H23, the airflow can be discharged from the radial air outlet H3 along the flow path F1 by the centrifugal fan 120. 110, as shown in FIG. 9, the housing 111 above the frame 110 is removed to show the flow path F1 located in the housing 110.
圖10為電子裝置之一實施例的剖視示意圖。請參閱圖1至圖10，在一實施例中，電子裝置200的主體210可具有一頂殼211。當風扇裝置100容置於主體210中時，風扇裝置100的軸向入風口H1可對應於主體21之頂殼211，並且風扇裝置100之軸流式風扇130到頂殼211之間可具有一間距T1，以使得氣流得以通過。因此，當風扇裝置100容置於主體210中時，突出於軸向入風口H1的局部之軸流式風扇130並不會接觸於主體21之頂殼211。10 is a schematic cross-sectional view of one embodiment of an electronic device. Referring to FIG. 1 to FIG. 10 , in an embodiment, the main body 210 of the electronic device 200 may have a top case 211 . When the fan device 100 is housed in the main body 210, the axial air inlet H1 of the fan device 100 may correspond to the top case 211 of the main body 21, and the axial fan 130 of the fan device 100 may have a spacing between the top case 211 T1, so that the airflow can pass. Therefore, when the fan device 100 is housed in the main body 210, the local axial fan 130 protruding from the axial air inlet H1 does not contact the top case 211 of the main body 21.
在一些實施態樣中，間距T1可介於0.8毫米（mm）至50毫米之間。In some embodiments, the spacing T1 can be between 0.8 millimeters (mm) and 50 millimeters.
