Description
本發明係關於一種水平對流扇，尤其是一種能夠以徑向方向導入及導出氣流的水平對流扇。The present invention relates to a horizontal convection fan, and more particularly to a horizontal convection fan capable of introducing and extracting airflow in a radial direction.
習知散熱風扇大致包含軸流式散熱風扇及鼓風式散熱風扇兩種。其中軸流式散熱風扇在軸向上分別具有相對之一軸向入風口及一軸向出風口，以便經由該軸向入風口導入氣流，再經由該軸向出風口導出氣流，進而提供散熱功能；又，鼓風式散熱風扇則是在軸向上具有一軸向入風口，以及在徑向上具有一徑向出風口，以便經由該軸向入風口導入氣流，再經由該徑向出風口側向導出氣流，而同樣具有散熱功能。Conventional cooling fans generally include two types of axial flow cooling fans and air blowing cooling fans. The axial flow type cooling fan has a pair of axial air inlets and an axial air outlet respectively in the axial direction, so as to introduce the airflow through the axial air inlet, and then the airflow is exhausted through the axial air outlet, thereby providing a heat dissipation function; In addition, the blasting type cooling fan has an axial air inlet in the axial direction and a radial air outlet in the radial direction, so as to introduce the airflow through the axial air inlet, and then laterally export through the radial air outlet. Airflow, but also has a heat dissipation function.
然而，以軸流式散熱風扇而言，由於僅可導引氣流朝軸向方向出風進行散熱，並無法導引氣流朝徑向方向出風進行散熱；因此，當軸流式散熱風扇應用於各式電子產品時，必須組裝於熱源之上方(如個人電腦之中央處理器之頂面)，導致該電子產品之軸向高度無法降低；又，以鼓風式散熱風扇而言，雖然可經由該徑向出風口側向導出氣流，惟仍必須利用該軸向入風口導入氣流，因此，並不適用於必須經由側邊方向導入氣流的電子產品(如手機或個人數位助理等)。However, in the case of the axial flow type cooling fan, since only the airflow can be guided to the air in the axial direction for heat dissipation, and the airflow cannot be guided to the wind in the radial direction for heat dissipation; therefore, when the axial flow type cooling fan is applied All kinds of electronic products must be assembled above the heat source (such as the top surface of the central processing unit of the personal computer), so that the axial height of the electronic product cannot be reduced; and, in the case of a blower type cooling fan, although The radial air outlet laterally derivates the airflow, but the airflow must still be introduced through the axial air inlet. Therefore, it is not suitable for electronic products (such as mobile phones or personal digital assistants) that must be introduced through the side direction.
為此，如中華民國公告第553323號「水平對流之風扇構造」新型專利案，係為一種在扇輪之徑向上，能夠以徑向方向導入及導出氣流的習知水平對流扇，以便適用於必須經由側邊方向導入氣流的電子產品。For this reason, the new patent case of "Fluority of Horizontal Convection Fans" of the Republic of China Bulletin No. 553323 is a conventional horizontal convection fan capable of introducing and extracting airflow in the radial direction in the radial direction of the fan wheel, so as to be suitable for The electronic product of the airflow must be introduced via the side direction.
請參照第1圖所示，係揭示另一種習知水平對流扇9的結構示意及其風向流場示意圖。該習知水平對流扇9係包含一框座91及一扇輪92。其中該框座91設有一側牆部911及一分流部912，以便於該框座91之二相鄰側邊分別形成一入風側93及一出風側94；該扇輪92係結合於該框座91的入風側93及出風側94之間，且該扇輪92可被一馬達定子驅動旋轉；藉此，當該扇輪92旋轉時，係可以驅使氣流經由該入風側93吸入且由該出風側94吹出，以提供預定之散熱功能。Referring to Fig. 1, a schematic diagram of another conventional horizontal convection fan 9 and a schematic diagram of its wind direction flow field are disclosed. The conventional horizontal convection fan 9 includes a frame 91 and a fan wheel 92. The frame 91 is provided with a side wall portion 911 and a diverting portion 912, so that an adjacent side of the frame 91 is formed with an air inlet side 93 and an air outlet side 94; the fan wheel 92 is coupled to Between the air inlet side 93 and the air outlet side 94 of the frame 91, the fan wheel 92 can be driven to rotate by a motor stator; thereby, when the fan wheel 92 rotates, the airflow can be driven through the air inlet side. 93 is drawn in and blown out by the air outlet side 94 to provide a predetermined heat dissipation function.
然而，習知水平對流扇9的扇輪92在驅使氣流(C1)經由該出風側94導出至外界時，由於該扇輪92在旋轉過程中，亦可能同時於該出風側94靠近該側牆部911一端的鄰近區域導入外界空氣而形成擾流(C2)，因此，習知水平對流扇9運作過程中，容易於該流場中產生顯著的風阻，使得經由該出風側94導出的氣流(C1)具有較大的阻力而產生空氣紊流等現象，以致於影響該出風側94的空氣流動及導流順暢度，甚至降低習知水平對流扇9的出風量及風壓，進而影響整體散熱效果。有鑑於上述問題，故習知水平對流扇9確實仍有加以改善之必要。However, when the fan wheel 92 of the conventional convection fan 9 drives the airflow (C1) to the outside through the air outlet side 94, since the fan wheel 92 is rotating, it may also be close to the wind outlet side 94. The adjacent area at one end of the side wall portion 911 introduces outside air to form a spoiler (C2). Therefore, during the operation of the conventional horizontal convection fan 9, it is easy to generate a significant wind resistance in the flow field, so that the air outlet side 94 is derived. The airflow (C1) has a large resistance to generate air turbulence and the like, so as to affect the air flow and the smoothness of the airflow side 94, and even reduce the air volume and wind pressure of the conventional convection fan 9. In turn, it affects the overall heat dissipation effect. In view of the above problems, it is necessary for the conventional convection fan 9 to be improved.
本發明目的乃解決上述習知水平對流扇所存在之問題，以提供一種水平對流扇，該水平對流扇係能夠有效導出該風扇流場內之氣流，以提升整體出風量者。The object of the present invention is to solve the problems of the above-mentioned conventional convection fans, and to provide a horizontal convection fan which can effectively derive the airflow in the fan flow field to enhance the overall airflow.

請配合參照第4圖所示，本發明水平對流扇主要技術特徵在於：該扇輪2之各葉片22係構成一旋轉範圍(R)；該扇輪2之旋轉範圍(R)具有最接近該扇框1接鄰於該入風口115之外周緣的一第一基準點(P1)，該第一基準點(P1)至該扇框1接鄰於該入風口115的外周緣係具有一第一最小距離(D1)；又，該扇輪2之旋轉範圍(R)另具有最接近該扇框1接鄰於該出風口116之外周緣的一第二基準點(P2)，該第二基準點(P2)至該扇框1接鄰於該出風口116的外周緣係具有一第二最小距離(D2)；其中該第二最小距離(D2)大於該第一最小距離(D1)。藉此，如第5圖所示，前述第二最小距離(D2)相對該第一最小距離(D1)所增加的距離係可以作為一導流距離，換言之，相較於如第1圖所示的習知水平對流扇，本發明水平對流扇的扇輪2驅使氣流導出至該出風口116的距離係相對延長，使該扇輪2在驅使氣流(C1)經由該出風口116導出至外界時，可以利用該導流距離形成較佳的導流作用，以便氣流可以更集中地自該出風口116導出，且亦兼可避免該扇輪2在旋轉過程中於該出風口116靠近該側牆部112之區域所形成的擾流阻力降至最低，進而提升本發明水平對流扇的整體出風量及風壓。Referring to FIG. 4, the main technical feature of the horizontal convection fan of the present invention is that each blade 22 of the fan wheel 2 constitutes a rotation range (R); the rotation range (R) of the fan wheel 2 has the closest The fan frame 1 is adjacent to a first reference point (P1) of the outer periphery of the air inlet 115, and the first reference point (P1) has a first outer edge of the fan frame 1 adjacent to the air inlet 115. a minimum distance (D1); in addition, the rotation range (R) of the fan wheel 2 has a second reference point (P2) closest to the periphery of the fan frame 1 adjacent to the outer air outlet 116, the second The reference point (P2) to the outer periphery of the fan frame 1 adjacent to the air outlet 116 has a second minimum distance (D2); wherein the second minimum distance (D2) is greater than the first minimum distance (D1). Thereby, as shown in FIG. 5, the distance increased by the second minimum distance (D2) relative to the first minimum distance (D1) can be used as a diversion distance, in other words, as shown in FIG. The conventional convection fan of the present invention, the fan 2 of the horizontal convection fan of the present invention drives the airflow to the air outlet 116 to be relatively extended, so that the fan wheel 2 drives the airflow (C1) to the outside through the air outlet 116. The guiding distance can be used to form a better guiding effect, so that the airflow can be more concentratedly discharged from the air outlet 116, and the fan wheel 2 can be prevented from approaching the side wall of the air outlet 116 during the rotating process. The turbulence resistance formed by the area of the portion 112 is minimized, thereby increasing the overall air volume and wind pressure of the convection fan of the present invention.
基於前述該第二最小距離(D2)大於該第一最小距離(D1)的技術概念，如第2及4圖所示，本發明水平對流扇之扇框1的出風口116係可以相對延伸出一增流板13，其中該扇框1的側牆部112具有分別接鄰該入風口115及出風口116的一第一端緣112a及一第二端緣112b，該增流板13自該分流部113朝該側牆部112之第二端緣112b的方向漸擴；藉由該增流板13的設計，使得該扇框1接鄰於該出風口116的外周緣可以遠離該扇輪2之基板21外周緣，以延長該導流距離，進而使前述提升出風量及風壓之效果更為顯著。Based on the technical concept that the second minimum distance (D2) is greater than the first minimum distance (D1), as shown in FIGS. 2 and 4, the air outlet 116 of the horizontal convection fan frame 1 of the present invention can be relatively extended. a side plate portion 112 of the fan frame 1 has a first end edge 112a and a second end edge 112b adjacent to the air inlet 115 and the air outlet 116, and the current plate 13 The diverting portion 113 is gradually enlarged toward the second end edge 112b of the side wall portion 112. The fan frame 13 is disposed adjacent to the outer peripheral edge of the air outlet 116 to be away from the fan wheel. The outer peripheral edge of the substrate 21 of 2 is used to extend the flow guiding distance, and the effect of increasing the air volume and the wind pressure is further remarkable.
更詳言之，請參照第4圖所示，該扇框1的出風口116具有分別接鄰該側牆部112及分流部113的二相對出風側緣116a，該增流板13則具有一導流側緣131，該導流側緣131即為該扇框1接鄰於該出風口116的外周緣；據此，前述該增流板13自該分流部113朝該側牆部112之第二端緣112b方向漸擴的標準，係在該扇輪2之徑向上，具有通過該導流側緣131的一漸擴延伸線L1，以及通過該出風口116之二相對出風側緣116a的一基準線L2，該漸擴延伸線L1及該基準線L2之間的夾角θ1係介於15°～30°。More specifically, referring to FIG. 4, the air outlet 116 of the fan frame 1 has two opposite air outlet edges 116a adjacent to the side wall portion 112 and the split portion 113, and the air flow plate 13 has a flow guiding side edge 131, the guiding side edge 131 is an outer circumference of the air outlet 116 adjacent to the air outlet 116; accordingly, the current increasing plate 13 is from the diverting portion 113 toward the side wall portion 112. The criterion for the diverging direction of the second end edge 112b is in the radial direction of the fan wheel 2, having a divergent extension line L1 passing through the flow guiding side edge 131, and the opposite air outlet side through the air outlet port 116. A reference line L2 of the edge 116a, the angle θ1 between the divergent extension line L1 and the reference line L2 is between 15° and 30°.
請參照第6圖所示，係揭示本發明水平對流扇基於前述夾角θ1介於15°～30°時，確實相較於習知水平對流扇可有效提升出風量及風壓的測試結果比對圖。其中線段A係為取樣該漸擴延伸線L1及該基準線L2之間的夾角θ1為15°的本發明水平對流扇；線段B係為取樣該漸擴延伸線L1及該基準線L2之間的夾角θ1為30°的本發明水平對流扇；線段C係為傳統水平對流扇。由該測試結果比對圖可以清楚看出，本發明水平對流扇的夾角θ1為15°及30°時，所提供的風量皆優於傳統水平對流扇，其中更以夾角θ1為30°時最佳。Referring to FIG. 6 , it is revealed that the horizontal convection fan of the present invention is based on the above-mentioned angle θ1 between 15° and 30°, and it is indeed better than the conventional level convection fan to effectively improve the air volume and wind pressure. Figure. The line segment A is a horizontal convection fan of the present invention in which the angle θ1 between the divergent extension line L1 and the reference line L2 is 15°; the line segment B is between the sampling extension line L1 and the reference line L2. The horizontal convection fan of the present invention has an angle θ1 of 30°; the line C is a conventional horizontal convection fan.
