Description
本發明有關於一種散熱風扇，特別有關於一種包含有一旋轉軸桿及一支撐軸桿的雙軸桿散熱風扇。
The invention relates to a cooling fan, in particular to a double shaft cooling fan including a rotating shaft and a supporting shaft.
由於筆記型電腦或平板電腦等電子產品趨向薄型設計，因此裝設於薄型電子產品中的散熱風扇，會因裝設空間的限制，而導致電子產品中的殼體或鍵盤等構件會有迫壓散熱風扇的扇輪之風險，進而造成扇輪無法正常運轉，如第1圖所示，習知一種散熱風扇10被裝設於一薄型筆記型電腦中，該筆記型電腦的一殼體21因外力觸壓或變型而迫壓該散熱風扇10的一扇輪11，導致該散熱風扇10無法正常運轉，或者造成該扇輪11摩擦該筆記型電腦的該殼體21而產生異音。
As electronic products such as notebook computers or tablet computers tend to be thinner, the cooling fans installed in thin electronic products may have pressure on the components such as the casing or keyboard in the electronic products due to the limitation of the installation space. The risk of the fan wheel of the cooling fan causes the fan wheel to fail to operate normally. As shown in FIG. 1 , a conventional cooling fan 10 is installed in a thin notebook computer, and a casing 21 of the notebook computer is When a force is pressed or deformed, a fan 11 of the cooling fan 10 is forced to press, causing the cooling fan 10 to fail to operate normally, or causing the fan wheel 11 to rub against the casing 21 of the notebook computer to generate an abnormal sound.
本發明之主要目的在於提供一種雙軸桿散熱風扇，其包含一基座、一軸承、一旋轉軸桿、一扇輪以及一支撐軸桿，該軸承結合於該基座，該軸承具有一軸孔，該旋轉軸桿可轉動地穿設該軸孔，該旋轉軸桿具有一通孔，該扇輪具有一輪轂，該扇輪以該輪轂結合於該旋轉軸桿，該支撐軸桿穿設於該旋轉軸桿的該通孔，該支撐軸桿具有一自由端及一固定端，該固定端結合於該基座，該自由端凸出於該輪轂。由於該雙軸桿散熱風扇的該旋轉軸桿可轉動地穿設於該軸承之該軸孔及該支撐軸桿穿設於該旋轉軸桿的該通孔，且該支撐軸桿的該自由端凸出於該扇輪的該輪轂，因此該雙軸桿散熱風扇的該扇輪是以該旋轉軸桿為轉軸轉動，並藉由該支撐軸桿的該自由端凸出於該輪轂，因此可防止筆記型電腦或平板電腦等電子商品的殼體、鍵盤或面板迫壓該雙軸桿散熱風扇的該扇輪，使得該雙軸桿散熱風扇可正常運轉。
