送风装置
摘要：
本发明提供一种送风装置，其具有：具有隔着轴向间隙而排列的多个平板的送风部；使送风部旋转的马达部；以及容纳送风部以及马达部的外壳。外壳具有在送风部的上部沿轴向贯通的吸气口和在送风部的径向外侧朝向径向开口的送风口。平板的至少一部分在其上表面以及下表面的至少一方具有作为沿着径向延伸的凹部或者凸部的多个引导部。在送风部旋转时，通过平板表面的粘性阻力以及离心力在平板之间产生朝向径向外侧的气流。由于在平板之间产生气流，该气流不易沿上下方向泄漏，能够提高送风效率。通过在平板的表面具有引导部，能够进一步提高送风效率。因此，即使在薄型化了的情况下，也不易导致送风效率下降，与具有叶轮的离心风扇相比，静音性优异。
摘要（英）：

This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; and a housing arranged to house the air blowing portion and the motor portion. The housing includes an air inlet and an air outlet. At least one of the flat plates includes, in at least one of an upper surface and a lower surface thereof, a plurality of guide portions each of which is a protruding portion or recessed portion arranged to extend in a radial direction. An air flow traveling radially outward is generated between the flat plates by viscous drag of surfaces of the flat plates and a centrifugal force. Since the air flow is generated between the flat plates, the air flow does not easily leak upwardly or downwardly.
