    摘要: A vortex flow blower includes a blower casing (3) having an annular flow passageway (3a) extending from an inlet port (3b) for receiving fluid to an outlet port (3c) for discharging the fluid, the outlet port (3c) being disposed adjacent to the inlet port (3b), an impeller (1) accommodated in the blower casing (3)
    for producing a vortex flow of the fluid in the annular flow passageway (3a), and a driver (30) for driving the impeller (1). Further, the vortex flow blower includes a member and/or a configuration thereof for enabling at least one of a reduction of temperature of the fluid discharged from the vortex flow blower, an increase in at least one of flow rate and pressure of the discharge fluid, a reduction in noise level of the vortex flow blower, and a compact configuration of the vortex flow blower.

    摘要: The present invention relates to a vortex flow blower used as an air source to be incorporated into general industrial machines. The vortex flow blower according to the present invention is characterized in that the shape of the blade in its impeller is three dimensionally formed such that at least the inner portion of the blade can be adapted to the three dimensional internal flow. According to the present invention, the aerodynamic performance can be significantly improved and the size of a vortex flow blower can be reduced. Furthermore, an impeller having three dimensionally shaped blades is manufactured by independently manufacturing the shroud and the blades and coupling them, so that the impeller of a complicated shape can be readily manufactured. Furthermore, since the blade can be made of a thin and light material, the secondary moment of inertia of the impeller can be reduced.
