該無刷馬達風扇於實際應用時,係透過該偵測元件偵測該 磁鐵之磁場變化(S極及N極之變化),該電路板依據該磁鐵之磁場變化以控制該複數線圈產生交變磁場,使得該複數線圈分別循序的排斥推擠該磁鐵之N磁極及S磁極,進而帶動該風扇旋轉,藉此對該電子裝置內部進 行散熱之動作。 In the actual application, the brushless motor fan detects the through the detecting component The magnetic field of the magnet changes (the change of the S pole and the N pole), the circuit board changes according to the magnetic field of the magnet to control the complex coil to generate an alternating magnetic field, so that the plurality of coils sequentially repel the N magnetic pole of the magnet and S a magnetic pole, which in turn drives the fan to rotate, thereby entering the inside of the electronic device The action of cooling.
然而,上述無刷散熱風扇之整體構造係於該外殼內依序層 疊有墊片、導磁件及圓形電路板,故該墊片、導磁件及電路板所形成之多層結構將增加該外殼之體積厚度,進而增加該無刷散熱風扇於該電子裝置內所佔用之空間,而造成該電子裝置之體積上升。 However, the overall structure of the above brushless cooling fan is in the order of the outer layer The gasket, the magnetic conductive member and the circular circuit board are stacked, so that the multi-layer structure formed by the gasket, the magnetic conductive member and the circuit board increases the volume thickness of the outer casing, thereby increasing the brushless cooling fan in the electronic device. The occupied space causes the volume of the electronic device to rise.
是以,如何解決習用無刷散熱風扇因其內部之多層結構所 造成體積厚度上升之問題,即為從事此行業之相關廠商所亟欲研究改善之方向所在者。 Therefore, how to solve the problem of the conventional brushless cooling fan due to its internal multilayer structure The problem of increasing volume thickness is the direction that the relevant manufacturers engaged in this industry are eager to study and improve.
故,發明人有鑑於上述缺失,乃蒐集相關資料,經由多方評估及考量,並以從事於此行業累積之多年經驗,經由不斷試作及修改,始設計出此種藉由該外殼之導磁部穿設於該電路板之定位孔,以供減少該外殼因凸設有該導磁部所產生之體積厚度的風扇結構。 Therefore, in view of the above-mentioned shortcomings, the inventors have collected relevant information, and through multi-party assessment and consideration, and through years of experience in the industry, through continuous trial and modification, the magnetic guide portion of the casing was designed. The locating hole is disposed in the circuit board for reducing the volume of the outer casing due to the convexity of the magnetic conductive portion.
