Description

風扇模組Fan module

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

電子系統中，風扇進氣端之氣流會受前方機構件及電子元件之佈置幹擾,易形成不規則之紊流進入風扇,使扇葉產生噪音。另外氣流於風扇出風口處瞬間之壓力變化亦會造成額外之噪音。該等噪音非但對操作人員造成困擾,未適當控制下甚至可能影響系統內組件之運作。In the electronic system, the airflow at the inlet end of the fan is disturbed by the arrangement of the front machine components and electronic components, and irregular turbulence is easily formed into the fan to cause noise in the fan blade. In addition, the instantaneous pressure change of the airflow at the fan outlet also causes additional noise. These noises are not only annoying to the operator, but may even affect the operation of components within the system without proper control.

鑒於以上內容，有必要提供一種利於減少噪音之風扇模組。In view of the above, it is necessary to provide a fan module that is advantageous for reducing noise.

一種風扇模組，包括一軸流風扇，軸流風扇之兩端分別設有一通風口，至少一通風口處設有一整流罩，該軸流風扇包括一位於中心之輪轂、圍設於輪轂周圍之複數葉片及一套設於葉片週邊之套筒，該整流罩包括一錐狀之罩體及複數固定片，罩體之小端正對軸流風扇之通風口並位於套筒與輪轂之間，該等固定片之一端固定於該罩體之大端，該等固定片之另一端固定於套筒。A fan module includes an axial fan. The axial fan has a venting port at each end thereof, and at least one vent is provided with a fairing. The axial fan includes a hub located at the center and surrounding the hub. a plurality of blades and a sleeve disposed around the periphery of the blade, the fairing includes a tapered cover body and a plurality of fixing pieces, the small end of the cover body facing the vent of the axial flow fan and located between the sleeve and the hub, the One end of the fixing piece is fixed to the large end of the cover, and the other end of the fixing piece is fixed to the sleeve.

相較先前技術，上述風扇模組之錐狀之整流罩可降低通風口處之紊流對風扇之葉片造成之幹擾，於不改變風扇結構之情況下，可有效之降低風扇之噪音。Compared with the prior art, the tapered fan-shaped fairing of the fan module can reduce the interference of the turbulence at the vent on the blade of the fan, and can effectively reduce the noise of the fan without changing the structure of the fan.

圖3係圖2沿III-III方向之剖視圖。Figure 3 is a cross-sectional view of Figure 2 taken along the line III-III.

請參照圖1及圖2，本發明風扇模組包括一軸流風扇10及分別設置於軸流風扇10兩端之兩整流罩20。Referring to FIG. 1 and FIG. 2 , the fan module of the present invention includes an axial fan 10 and two fairings 20 respectively disposed at two ends of the axial fan 10 .

該軸流風扇10之兩端分別設有一通風口15。該軸流風扇10包括一位於中心之輪轂11、圍設於輪轂11周圍之複數葉片12及一套設於葉片12週邊之套筒13。套筒13之兩端還垂直設有兩端板131，套筒13之外表面沿軸向設有複數連接兩端板131之平板部132。A vent 15 is respectively disposed at each end of the axial fan 10. The axial fan 10 includes a central hub 11 , a plurality of blades 12 surrounding the hub 11 , and a sleeve 13 disposed around the periphery of the blade 12 . Both ends of the sleeve 13 are also vertically provided with two end plates 131. The outer surface of the sleeve 13 is provided with a plurality of flat plate portions 132 connecting the end plates 131 in the axial direction.

請一併參照圖1及圖3，整流罩20包括一錐狀之罩體21及複數設置於罩體21之外側並自罩體21之大端211之邊緣處向罩體21之小端212延伸形成之平行於整流罩20之中心軸線之固定片22，該等固定片22為彈性薄片。Referring to FIG. 1 and FIG. 3 together, the fairing 20 includes a tapered cover 21 and a plurality of small ends 212 disposed on the outer side of the cover 21 and from the edge of the large end 211 of the cover 21 toward the cover 21. The fixing piece 22 is formed to be parallel to the central axis of the fairing 20, and the fixing pieces 22 are elastic sheets.

本實施方式中，輪轂11為圓筒狀。罩體21為圓錐筒狀。罩體21之大端211之直徑大於軸流風扇10之套筒13之外徑。罩體21之小端212之直徑大於軸流風扇10之輪轂11之直徑，小於套筒13之內徑。罩體21之內表面之傾斜度α之選取範圍為20度～30度，優選傾斜度為20度。In the present embodiment, the hub 11 has a cylindrical shape. The cover 21 has a conical tubular shape. The large end 211 of the cover 21 has a larger diameter than the outer diameter of the sleeve 13 of the axial fan 10. The diameter of the small end 212 of the cover 21 is larger than the diameter of the hub 11 of the axial fan 10 and smaller than the inner diameter of the sleeve 13. The inclination α of the inner surface of the cover 21 is selected from the range of 20 to 30 degrees, preferably 20 degrees.

請一併參照圖2，安裝整流罩20時，分別將兩整流罩20之罩體21之小端212對準軸流風扇10之兩通風口15，使罩體21之小端212與軸流風扇10之輪轂11間隔一定之距離，固定片22彈性抵接於端板131之外側對應之平板部132。固定片22與平板部132之間亦可以塗設膠水相黏合。即將兩整流罩20裝設於軸流風扇10之兩端。Referring to FIG. 2 together, when the fairing 20 is installed, the small ends 212 of the shells 21 of the two fairings 20 are respectively aligned with the two vents 15 of the axial fan 10, so that the small end 212 and the axial flow of the shell 21 are axially flowed. The hub 11 of the fan 10 is spaced apart by a certain distance, and the fixing piece 22 is elastically abutted against the corresponding flat portion 132 on the outer side of the end plate 131. The fixing piece 22 and the flat plate portion 132 may also be glued to each other by applying glue. That is, the two fairings 20 are installed at both ends of the axial fan 10.

軸流風扇10之前端的通風口15的整流罩20可對由於前方機構件及電子元件之幹擾而產生紊流進行整流，降低紊流對扇葉12之衝擊，從而降低軸流風扇10之前端噪音。The fairing 20 of the vent 15 of the front end of the axial fan 10 can rectify the turbulence caused by the interference of the front machine components and the electronic components, reducing the impact of the turbulence on the blade 12, thereby reducing the noise at the front end of the axial fan 10. .

軸流風扇10之後端的通風口15的整流罩20可降低瞬間之氣流壓力之變化，對流出氣流起到緩衝作用，從而降低軸流風扇10後端噪音。The fairing 20 of the vent 15 of the rear end of the axial fan 10 can reduce the instantaneous change of the airflow pressure, and buffer the outflow airflow, thereby reducing the noise of the rear end of the axial fan 10.

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.
