Description

離心式風扇 Centrifugal fan

本揭露有關於一種離心式風扇。 The disclosure relates to a centrifugal fan.

一般雙出風口的離心風扇的兩個出風口可以分為主要出風口及次要出風口。氣流沿扇葉旋轉方向，到達的第一個出風口為主要出風口，其風量及風壓較大，接著氣流繼續沿扇葉旋轉方向，到達第二個出風口為次要出風口，此第二出風口風量及風壓較小。由於，兩個出風口的氣流的出風角度及分佈不同，而造成了兩個出風口處的散熱能力不均，並且產生噪音。 Generally, the two air outlets of the centrifugal fan with double air outlets can be divided into a main air outlet and a secondary air outlet. The airflow is in the direction of rotation of the blade, and the first air outlet that arrives is the main air outlet, and the air volume and wind pressure are large, and then the airflow continues along the direction of the blade rotation, and the second air outlet is the secondary air outlet. The air volume and wind pressure of the second outlet are small. Because the air outlet angles and distributions of the two air outlets are different, the heat dissipation capability at the two air outlets is uneven, and noise is generated.

本揭露提出一種離心式風扇，包含殼體、分隔件以及扇葉轉子。殼體包含頂板、底板以及連接於底板與頂板之間的側牆。頂板、底板與側牆共同形成第一出風口以及第二出風口。分隔件設置於殼體內，連接於底板與頂板之間，並將殼體內分隔出與第一出風口相連的第一空間以及與第二出風口相連的第二空間。分隔件具有第一開口，第一開口連通第一空間以及第二空間。扇葉轉子可轉動地設置於第二空間中。 The present disclosure proposes a centrifugal fan including a housing, a partition, and a blade rotor. The housing includes a top plate, a bottom plate, and a side wall connected between the bottom plate and the top plate. The top plate, the bottom plate and the side wall together form a first air outlet and a second air outlet. The partitioning member is disposed in the casing, and is connected between the bottom plate and the top plate, and separates the inner space of the casing from the first space connected to the first air outlet and the second space connected to the second air outlet. The partition has a first opening that communicates with the first space and the second space. The blade rotor is rotatably disposed in the second space.

總結而言，本揭露提出的離心式風扇，藉由殼體形成第一出風口以及第二出風口，可以提供不同方向的氣流。而在第一出風口以及扇葉轉子的轉軸之間設置有分隔件，增加了一段增壓區，使得氣流在離心式風扇內更為平穩。在分隔件上設置有第一開口以及第二開口，並藉由調整第一開口與第二開口的尺寸、位置以及形狀，來調整第一出風口以及第二出風口的出風量以及氣流平穩度。 In summary, the centrifugal fan proposed by the present disclosure can provide airflow in different directions by forming a first air outlet and a second air outlet through the casing. A partition member is disposed between the first air outlet and the rotating shaft of the blade rotor, and a section of the boosting zone is added to make the airflow more stable in the centrifugal fan. The first opening and the second opening are disposed on the partition, and the air volume and airflow stability of the first air outlet and the second air outlet are adjusted by adjusting the size, position and shape of the first opening and the second opening. .

本揭露提出一種離心式風扇，具有多個出風口以適應不同的散熱要求。請參照第1圖以及第2圖。第1圖繪示依據本揭露一實施方式的離心式風扇100的立體圖。第2圖繪示第1圖中離心式風扇100的***圖。如第1圖以及第2圖所示， 本揭露提出的離心式風扇100包含殼體110、分隔件120以及扇葉轉子130。 The present disclosure proposes a centrifugal fan having a plurality of air outlets to accommodate different heat dissipation requirements. Please refer to Figure 1 and Figure 2. FIG. 1 is a perspective view of a centrifugal fan 100 according to an embodiment of the present disclosure. FIG. 2 is an exploded view of the centrifugal fan 100 in FIG. 1. As shown in Figure 1 and Figure 2, The centrifugal fan 100 proposed by the present disclosure includes a housing 110, a partition 120, and a blade rotor 130.

如第2圖所示，殼體110包含頂板111、底板112以及側牆113，側牆113連接頂板111以及底板112，並形成容置空間。頂板111、底板112以及側牆113還定義出第一出風口110a以及第二出風口110b。側牆113在靠近第二出風口110b的位置具有舌口113a。 As shown in FIG. 2, the housing 110 includes a top plate 111, a bottom plate 112, and a side wall 113. The side wall 113 connects the top plate 111 and the bottom plate 112 and forms an accommodation space. The top plate 111, the bottom plate 112, and the side wall 113 further define a first air outlet 110a and a second air outlet 110b. The side wall 113 has a tongue 113a at a position close to the second air outlet 110b.

於本實施例中，第一出風口110a的出風方向垂直於第二出風口110b的出風方向。於一實施例中，第一出風口110a的出風方向與第二出風口110b的出風方向可依據實務需求任意改變。 In this embodiment, the air outlet direction of the first air outlet 110a is perpendicular to the air outlet direction of the second air outlet 110b. In an embodiment, the air outlet direction of the first air outlet 110a and the air outlet direction of the second air outlet 110b may be arbitrarily changed according to actual needs.

如第2圖所示，分隔件120設置於殼體110內，並連接頂板111、側牆113與底板112。分隔件120在殼體110內分隔出第一空間S1與第二空間S2。其中第一空間S1是指與第一出風口110a相連的空間，而第二空間S2是指與第二出風口110b相連的空間。分隔件120具有第一開口120a與第二開口120b。氣流可以藉由第一開口120a與第二開口120b在第一空間S1與第二空間S2之間流通。 As shown in FIG. 2, the partition member 120 is disposed in the casing 110 and connects the top plate 111, the side wall 113, and the bottom plate 112. The partition 120 separates the first space S1 and the second space S2 within the housing 110. The first space S1 refers to a space connected to the first air outlet 110a, and the second space S2 refers to a space connected to the second air outlet 110b. The separator 120 has a first opening 120a and a second opening 120b. The air flow may flow between the first space S1 and the second space S2 through the first opening 120a and the second opening 120b.

如第2圖所示，扇葉轉子130可轉動地設置於第二空間S2中。扇葉轉子130設置於舌口113a以及分隔件120之間的位置。 As shown in Fig. 2, the blade rotor 130 is rotatably disposed in the second space S2. The blade rotor 130 is disposed at a position between the tongue 113a and the partition 120.

本實施方式中，扇葉轉子130包含轉軸131以及多個扇葉132。扇葉轉子130在殼體110內基於軸線X往旋轉方向R轉動。頂板111上對應於轉軸131的位置設置有一個入風口 111a。如第1圖所示，入風口111a完整的暴露出轉軸131，並部分地暴露出扇葉132。藉由以上配置，扇葉轉子130在旋轉時可以由入風口111a吸入氣流，使氣流流向第一出風口110a以及第二出風口110b。 In the present embodiment, the blade rotor 130 includes a rotating shaft 131 and a plurality of blades 132. The blade rotor 130 rotates in the housing 110 in the direction of rotation R based on the axis X. An air inlet is disposed on the top plate 111 corresponding to the position of the rotating shaft 131. 111a. As shown in Fig. 1, the air inlet 111a completely exposes the rotating shaft 131 and partially exposes the fan blade 132. With the above configuration, the blade rotor 130 can take in the airflow from the air inlet 111a while rotating, and the airflow flows to the first air outlet 110a and the second air outlet 110b.

請參照第3圖，其繪示第1圖中離心式風扇100去除頂板111後的俯視示意圖。如第3圖所示，扇葉轉子130基於軸線X沿著旋轉方向R轉動。旋轉方向R是指第3圖圖面逆時鐘的方向。側牆113與轉軸131之間的距離，由舌口113a沿著旋轉方向R至第一出風口110a漸擴。分隔件120與轉軸131之間的距離，由舌口113a沿著旋轉方向R至第二出風口110b漸擴。氣流進入扇葉132之間的區域後，會被扇葉132推動而沿著旋轉方向R流動。側牆113、分隔件120與轉軸131之間的漸擴造型使氣流的風阻逐漸變小(靜壓隨之變小)，進而使得氣流的風速逐漸變大(動壓隨之變大)。因此，側牆113與分隔件120以及轉軸131之間由舌口113a沿著旋轉方向R至第二出風口110b的區域可定義為增壓區A(亦即，動壓增加的區域。) Please refer to FIG. 3 , which is a schematic top view of the centrifugal fan 100 in FIG. 1 after the top plate 111 is removed. As shown in Fig. 3, the blade rotor 130 rotates in the rotational direction R based on the axis X. The direction of rotation R refers to the direction of the third picture opposite to the clock. The distance between the side wall 113 and the rotating shaft 131 is gradually expanded by the tongue 113a along the rotational direction R to the first air outlet 110a. The distance between the spacer 120 and the rotating shaft 131 is gradually expanded by the tongue 113a along the rotational direction R to the second air outlet 110b. After the airflow enters the area between the blades 132, it is pushed by the blades 132 to flow in the direction of rotation R. The progressive expansion between the side wall 113, the partition member 120 and the rotating shaft 131 gradually reduces the wind resistance of the airflow (the static pressure becomes smaller), and the wind speed of the airflow gradually becomes larger (the dynamic pressure becomes larger). Therefore, the region between the side wall 113 and the partition member 120 and the rotating shaft 131 from the tongue opening 113a in the rotational direction R to the second air outlet 110b can be defined as the pressurized region A (that is, the region where the dynamic pressure is increased.)

如第3圖所示，由於分隔件120具有第一開口120a以及第二開口120b，因此氣流經過分隔件120與轉軸131之間的區域時，一部分的氣流會由第二空間S2通過第一開口120a以及第二開口120b，並經由第一空間S1往第一出風口110a流動。其餘氣流沿著旋轉方向R繼續往第二出風口110b的方向流動。 As shown in FIG. 3, since the partition 120 has the first opening 120a and the second opening 120b, when the airflow passes through the area between the partition 120 and the rotating shaft 131, a part of the airflow passes through the first opening through the second space S2. 120a and the second opening 120b flow through the first space S1 to the first air outlet 110a. The remaining airflow continues to flow in the direction of the second air outlet 110b along the rotational direction R.

如第3圖所示，在離心式風扇100的實施方式中，側牆113從舌口113a起算，沿著旋轉方向R(即圖面逆時鐘方向) 到連接至分隔件120的位置整體為弧面，如此可以確保增壓區A的氣流流動平順。但在一些實施方式中，可以依據實務需求適當將弧面調整為其他形狀，諸如各種圓錐曲線或流線形曲線。 As shown in FIG. 3, in the embodiment of the centrifugal fan 100, the side wall 113 is calculated from the tongue 113a along the rotation direction R (ie, the drawing is counterclockwise). The position to the partition 120 is entirely curved, which ensures that the flow of the plenum A is smooth. However, in some embodiments, the arcuate surface can be appropriately adjusted to other shapes, such as various conic curves or streamlined curves, depending on practical requirements.

如第3圖所示，在離心式風扇100的實施方式中，分隔件120朝向扇葉轉子130的一側具有弧面，且弧面的曲率中心位於第二空間S2中。分隔件120的弧面可以確保增壓區A的氣流流動平順。在一實施方式中，可以依據實務需求適當將弧面調整為其他形狀，諸如各種圓錐曲線或流線形曲線。 As shown in FIG. 3, in the embodiment of the centrifugal fan 100, the partition 120 has a curved surface toward one side of the blade rotor 130, and the center of curvature of the curved surface is located in the second space S2. The curved surface of the partition 120 ensures that the flow of the plenum A is smooth. In an embodiment, the arcuate surface may be appropriately adjusted to other shapes, such as various conic curves or streamlined curves, depending on practical requirements.

如第3圖所示，在離心式風扇100的實施方式中，側牆113與分隔件120圍繞出的一部分第二空間S2為圓柱形空間，使得在第二空間S2中的氣流流動平順。 As shown in FIG. 3, in the embodiment of the centrifugal fan 100, the side wall 113 and a portion of the second space S2 surrounded by the partition member 120 are cylindrical spaces, so that the airflow in the second space S2 flows smoothly.

請參照第4圖，其繪示第3圖中移除了扇葉132的離心式風扇100，並標示出第一開口120a以及第二開口120b的位置關係。如第4圖所示，在垂直軸線X的平面(即第4圖圖面)上，舌口113a與軸線X的連線定義為第一基準線L1；第二出風口110b遠離舌口113a的一端與軸線X的連線定義為第二基準線L2；而第一開口120a內一點與軸線X的連線定義為第三基準線L3。 Referring to FIG. 4, the centrifugal fan 100 with the blade 132 removed in FIG. 3 is illustrated, and the positional relationship between the first opening 120a and the second opening 120b is indicated. As shown in Fig. 4, on the plane of the vertical axis X (i.e., the fourth drawing), the line connecting the tongue 113a to the axis X is defined as the first reference line L1; the second air outlet 110b is away from the tongue 113a. A line connecting one end to the axis X is defined as a second reference line L2; and a line connecting a point in the first opening 120a with the axis X is defined as a third reference line L3.

如第4圖所示，由第一基準線L1至第二基準線L2沿著旋轉方向R旋轉有一第一角度R1(具體而言指的是第一基準線L1與第二基準線L2沿著圖面逆時鐘方向所夾出的鈍角)。由第一基準線L1至第三基準線L3沿著旋轉方向R旋轉有一第二角度R2(具體而言指的是第一基準線L1與第三基準線L3沿 著圖面逆時鐘方向所夾出的鈍角)。如第4圖所示，由第一基準線L1沿著旋轉方向R旋轉第一角度R1的10%的位置標示有10%。舉例而言，當第一角度R1為300度時，第一角度R1的10%為30度，第一基準線L1沿著旋轉方向R旋轉30度的位置即標有10%。同樣的，沿著旋轉方向R旋轉第一角度R1的20%的位置標示有20%，其餘依此類推。 As shown in FIG. 4, the first reference line L1 to the second reference line L2 are rotated in the rotation direction R by a first angle R1 (specifically, the first reference line L1 and the second reference line L2 are along The obtuse angle that the drawing faces in the counterclockwise direction). Rotating from the first reference line L1 to the third reference line L3 along the rotation direction R has a second angle R2 (specifically, referring to the first reference line L1 and the third reference line L3 along The obtuse angle that the figure faces in the counterclockwise direction). As shown in Fig. 4, a position where 10% of the first angle R1 is rotated by the first reference line L1 in the rotational direction R is indicated by 10%. For example, when the first angle R1 is 300 degrees, 10% of the first angle R1 is 30 degrees, and the position where the first reference line L1 is rotated by 30 degrees along the rotation direction R is marked with 10%. Similarly, the position where 20% of the first angle R1 is rotated along the rotational direction R is indicated by 20%, and so on.

在本實施方式中，第二空間S2在第4圖中標示有70%~90%的位置的氣壓最小，因此在標示有70%~90%的位置設置第一開口120a，能降低第二空間S2內的氣壓損失。實際應用時，可依據需求更動第一開口120a的位置，本揭露並不以上述為限。在不同實施方式中，氣壓最低的位置並不一定位於70%~90%的位置，可依據實務狀況設計第一開口120a的位置。 In the present embodiment, the second space S2 is marked with a minimum air pressure of 70% to 90% in the fourth figure, so that the first opening 120a is provided at a position marked 70% to 90%, which can reduce the second space. Loss of air pressure in S2. In actual application, the position of the first opening 120a can be changed according to requirements, and the disclosure is not limited to the above. In different embodiments, the position with the lowest air pressure is not necessarily located at 70% to 90%, and the position of the first opening 120a can be designed according to the actual situation.

在離心式風扇100的實施方式中，通過第一開口120a的氣流可能僅會流向第一出風口110a靠近第二出風口110b的部分。為了使第一出風口110a各處流出的氣流均勻，可將第二開口120b設置於分隔件120上比第一出風口110a更遠離第二出風口110b的位置，使得第二開口120b的氣流可流向第一出風口110a遠離第二出風口110b的部分。藉由以上設置，第一出風口110a整體流出的氣流較為均勻。 In the embodiment of the centrifugal fan 100, the air flow through the first opening 120a may only flow to a portion of the first air outlet 110a that is adjacent to the second air outlet 110b. In order to make the airflow flowing out from the first air outlet 110a uniform, the second opening 120b can be disposed on the partition 120 at a position farther away from the second air outlet 110b than the first air outlet 110a, so that the airflow of the second opening 120b can be The flow to the portion of the first air outlet 110a away from the second air outlet 110b. With the above arrangement, the airflow flowing out of the first air outlet 110a as a whole is relatively uniform.

在離心式風扇100的實施方式中，第二開口120b的面積小於第一開口120a的面積。如前所說明，由於第一開口120a會設置在氣壓較低的位置，每單位面積的流量較低，因此第一開口120a對第二出風口110b造成的性能影響較小。相比之下，第二開口120b則對第二出風口110b造成的性能影響較 大。因此，於一些實施方式中，可將第二開口120b的面積設計小於第一開口120a的面積。如此一來，可以在不大幅影響第二出風口110b的流量、流速、均勻度等性能的前提下，提供第一出風口110a的出風氣流。在離心式風扇100的實施方式中，第一開口120a與第二開口120b的面積加總，介於第二出風口110b的面積的10%~50%之間。以上設計使得第一出風口110a的出風量可以小於第二出風口110b，使得第二出風口110b仍可保持較高的氣流量。於實際應用中，可自由調整第一開口120a與第二開口120b的面積，來控制第一出風口110a與第二出風口110b的出風量比例關係。 In an embodiment of the centrifugal fan 100, the area of the second opening 120b is smaller than the area of the first opening 120a. As explained above, since the first opening 120a is disposed at a position where the air pressure is lower, the flow rate per unit area is lower, so the performance of the first opening 120a on the second air outlet 110b is less affected. In contrast, the effect of the second opening 120b on the performance of the second air outlet 110b is Big. Therefore, in some embodiments, the area of the second opening 120b can be designed to be smaller than the area of the first opening 120a. In this way, the airflow of the first air outlet 110a can be provided without significantly affecting the performance of the flow rate, the flow rate, the uniformity, and the like of the second air outlet 110b. In the embodiment of the centrifugal fan 100, the area of the first opening 120a and the second opening 120b is increased by between 10% and 50% of the area of the second air outlet 110b. The above design allows the air outlet of the first air outlet 110a to be smaller than the second air outlet 110b, so that the second air outlet 110b can still maintain a high air flow. In practical applications, the area of the first opening 120a and the second opening 120b can be freely adjusted to control the proportional relationship between the air outlets of the first air outlet 110a and the second air outlet 110b.

請參考第5圖，其繪示由第4圖的離心式風扇100的第一出風口110a看向分隔件120的示意圖。如第5圖所示，第一開口120a與第二開口120b的形狀皆為矩形。在一些實施方式中，第一開口120a與第二開口120b具有其他形狀，可依據實務需求任意改變第一開口120a與第二開口120b的外型。 Please refer to FIG. 5 , which is a schematic view of the partition member 120 viewed from the first air outlet 110 a of the centrifugal fan 100 of FIG. 4 . As shown in FIG. 5, the shapes of the first opening 120a and the second opening 120b are both rectangular. In some embodiments, the first opening 120a and the second opening 120b have other shapes, and the appearances of the first opening 120a and the second opening 120b can be arbitrarily changed according to practical requirements.

如第5圖所示，第一開口120a與第二開口120b皆連接至頂板111(請參考第2圖)。在一些實施方式中，第一開口120a與第二開口120b可以連接至底板112。在一些實施方式中，第一開口120a與第二開口120b可以由底板112連接至頂板111。在一些實施方式中，第一開口120a與第二開口120b位於分隔件120中，而並未連接至頂板111或底板112。可依據實務需求任意改變第一開口120a與第二開口120b的設置位置。 As shown in FIG. 5, the first opening 120a and the second opening 120b are both connected to the top plate 111 (please refer to FIG. 2). In some embodiments, the first opening 120a and the second opening 120b can be coupled to the bottom plate 112. In some embodiments, the first opening 120a and the second opening 120b may be connected to the top plate 111 by the bottom plate 112. In some embodiments, the first opening 120a and the second opening 120b are located in the divider 120 and are not connected to the top plate 111 or the bottom plate 112. The setting positions of the first opening 120a and the second opening 120b can be arbitrarily changed according to actual needs.

在一些實施方式中，分隔件120還可以增設有第三開口、第四開口...。於一實施例中，增設的開口皆位於第4 圖中70%~90%的範圍內。可以依據實務需求任意增設開口，本揭露並不以上述為限。 In some embodiments, the partition 120 may also be provided with a third opening, a fourth opening, . In an embodiment, the additional openings are located at the 4th The figure is in the range of 70% to 90%. The opening may be arbitrarily added according to the actual needs, and the disclosure is not limited to the above.

本揭露提出的離心式風扇，藉由殼體形成第一出風口以及第二出風口，可以提供不同方向的氣流。而在第一出風口以及扇葉轉子的轉軸之間設置有分隔件，增加了一段增壓區，使得氣流在離心式風扇內更為平穩。在分隔件上設置有第一開口以及第二開口，並藉由調整第一開口與第二開口的尺寸、位置以及形狀，得以調整第一出風口以及第二出風口的出風量以及氣流平穩度。 The centrifugal fan proposed by the present disclosure can provide airflow in different directions by forming a first air outlet and a second air outlet through the casing. A partition member is disposed between the first air outlet and the rotating shaft of the blade rotor, and a section of the boosting zone is added to make the airflow more stable in the centrifugal fan. The first opening and the second opening are disposed on the partition, and the air volume and airflow stability of the first air outlet and the second air outlet are adjusted by adjusting the size, position and shape of the first opening and the second opening. .
