摘要： A fan system with enhanced air flow-static pressure characteristics and reduced fan noise compared to the related art is provided. The number of duct blades of a duct is the same as the number of stationary blades of an axial flow fan located in front of the duct, and the duct blades correspond to the stationary blades respectively. An end surface of a rear end portion of each stationary blade and an end surface of a front portion of a duct blade corresponding to the stationary blade have the same shape, and they align together and contact each other to form one composite stationary blade, with a discharge port of each axial flow fan communicating with an inlet port of a duct housing located behind the axial flow fan.
摘要翻译：提供了一种与现有技术相比具有增强的空气流静压特性和降低风扇噪声的风扇系统。管道的管道叶片的数量与位于管道前方的轴流风扇的固定叶片的数量相同，并且管道叶片分别对应于固定叶片。每个固定叶片的后端部的端面和对应于固定叶片的管道叶片的前部的端面具有相同的形状，并且它们对齐并彼此接触以形成一个复合固定叶片，其中每个轴流风扇的排放口与位于轴流风扇后面的管道壳体的入口连通。

摘要： Four tapered portions are formed on an end portion of an inner wall surface of an air channel at four locations corresponding to four corners of the profile of a surface of a housing where a suction port is formed. The four tapered portions are each inclined outwardly in a radial direction of a rotary shaft from a discharge port side toward the suction port side and extending in a rotational direction of an impeller. The tapered portions each include a main portion which is shaped such that an angle formed between the main portion and an axis of the rotary shaft gradually becomes smaller from one end of the main portion located rearward as viewed in the rotational direction of the impeller toward the other end of the main portion located forward as viewed in the rotational direction of the impeller.
摘要翻译：在对应于形成有吸入口的壳体的表面的轮廓的四个位置的四个位置处，在空气通道的内壁表面的端部上形成有四个锥形部分。四个锥形部分分别在旋转轴的径向方向上从排出口侧朝向吸入口侧向外倾斜并沿叶轮的旋转方向延伸。锥形部分各自包括主要部分，其主要部分形成为使得从旋转轴的主要部分和轴线之间形成的角度从沿叶轮的旋转方向观察的向后的主要部分的一端逐渐变小主叶片的另一端位于叶轮旋转方向的前方。
