Description
本創作係有關於一種散熱裝置，尤指一種不等高扇葉之風扇。This creation is about a heat sink, especially a fan that does not have a high fan blade.
隨著科技之進步，電腦等3C產品之功能也越來越多元，其內部的電子元件所產生的熱量也更為可觀，若電子元件溫度過高則會影響運作時的性能及穩定性，所以電子元件大多需要散熱裝置散熱，以確保電子元件能正常運作。其中，風扇為常見的一種散熱裝置。With the advancement of technology, the functions of 3C products such as computers are becoming more diverse, and the heat generated by the internal electronic components is also more impressive.
