    • A serial fan module includes a first fan, a second fan and a plurality of guide elements. The first fan has a first frame body and a first impeller disposed within the first frame body. The second fan has a second frame body and a second impeller disposed within the second frame body. The guide elements are disposed between the first impeller and the second impeller, wherein the guide elements guide airflow from the first fan to the second fan. Each of the guide elements has an axial extended part and an inclined part and the inclined part meets the axial extended part at a camber angle. Each of the inclined part has an inner edge toward the first impeller and each of the axial extended part has an outer edge toward the second impeller.
    • 串行风扇模块包括第一风扇,第二风扇和多个引导元件。 第一风扇具有设置在第一框体内的第一框体和第一叶轮。 第二风扇具有设置在第二框体内的第二框体和第二叶轮。 引导元件设置在第一叶轮和第二叶轮之间,其中引导元件引导从第一风扇到第二风扇的气流。 每个引导元件具有轴向延伸部分和倾斜部分,并且倾斜部分以外倾角与轴向延伸部分相接。 每个倾斜部分具有朝向第一叶轮的内边缘,并且每个轴向延伸部分具有朝向第二叶轮的外边缘。

    • A fan includes an airflow guiding structure, an impeller and a guiding ring. The outer radius of the airflow guiding structure increases gradually from the top of the airflow guiding structure to the bottom of the airflow guiding structure. The airflow guiding structure includes a plurality of fins and a first space for accommodating a circuit device. The impeller is disposed on the airflow guiding structure and has a hub and several blades. The guiding ring connects to the airflow guiding structure via at least one connecting element. A predetermined distance is arranged between the inner surface of the guiding ring and the outer edges of the blades. An inlet is formed at the top of the guiding ring, and an outlet is formed between the bottom of the guiding ring and the outer surface of a sidewall of the airflow guiding structure. When the impeller rotates, the airflow enters the fan from the inlet and flows along the outer surface of the sidewall of the airflow guiding structure, then the airflow exits the fan through the outlet. The direction of the airflow passing through the outlet is different from the direction of the airflow passing through the inlet.
    • 风扇包括气流引导结构,叶轮和导向环。 气流引导结构的外半径从气流引导结构的顶部逐渐增加到气流引导结构的底部。 气流引导结构包括多个翅片和用于容纳电路装置的第一空间。 叶轮设置在气流引导结构上,并具有轮毂和多个叶片。 引导环通过至少一个连接元件连接到气流引导结构。 在引导环的内表面和叶片的外边缘之间布置预定距离。 入口形成在引导环的顶部,并且在引导环的底部和气流引导结构的侧壁的外表面之间形成出口。 当叶轮旋转时,气流从入口进入风扇并沿着气流引导结构的侧壁的外表面流动,然后气流通过出口离开风扇。 通过出口的气流方向与通过入口的气流方向不同。
