    摘要： Four tapered portions (65) are formed on an end portion of an inner wall surface of an air channel (48) at four locations corresponding to four corners of the profile of a surface (52) of a housing (5) where a suction port (51) is formed. The four tapered portions (65) are each inclined outwardly in a radial direction of a rotary shaft (9) from a discharge port (53) side toward the suction port side and extending in a rotational direction of an impeller (3). The tapered portions (65) each include a main portion (65A) which is shaped such that an angle (θ1-θ4) formed between the main portion (65A) and an axis (A) of the rotary shaft (9) gradually becomes smaller from one end (65g) of the main portion (65A) located rearward as viewed in the rotational direction of the impeller (3) toward the other end (65e) of the main portion (65A) located forward as viewed in the rotational direction of the impeller (3).

    摘要： A fan module and an electronic device using the fan module are provided. The fan module includes a housing, a fan blade assembly, and a fan hub. The housing has a first surface on which plural wind guiding structures are arranged. The fan blade assembly is pivoted to the housing through the fan hub and adapted to rotate along a rotation direction. The wind guiding structures are arranged along a circumferential direction of the fan hub to guide a wind flow into the housing while the fan blade assembly is being rotated.

    摘要： An arrangement of an impeller (3) on a rotating part, preferably on an electric motor (1), in particular on an external rotor motor, wherein the torque of the motor (1) is transmitted to the impeller (3) by a rotationally secure connection between the rotor (2) of the motor (1) and the impeller (3) or its impeller hub (4), and wherein the connection is created by means of a press fit between the impeller hub (4) and the rotor (2), with integration of a sleeve (6) which is preferably securely assigned to the impeller hub (4) and which takes up mechanical stresses, is characterized in that the sleeve (6) is polygonal and is pressed onto the surface of the rotor (2), with at least minor deformation, forming axial contact surfaces. Also specified is a method for producing such an arrangement.

    摘要： An axial flow fan is provided wherein an amount of dropping at the inflection point appearing in air volume - static pressure characteristics may be reduced and noise may also be reduced as compared to conventional axial fans.
    A blade (5) has a curved portion (4). The curved portion (4) is formed in the vicinity of a radially outer end portion (5B) positioned opposite to the base portion (5A) in the radial direction of the peripheral wall portion of the hub. The curved portion is convex in the rotation direction (RD), concave in the direction opposite to the rotation direction (RD), and extends along the radially outer end portion (5B) of the blade (5). The curved portion extends from a rear end edge (5C) of the blade (5) positioned on a side where one end (5Aa) of the base portion (5A) of the blade is positioned and extending in the radial direction of the hub to the vicinity of a front end edge (5D) of the blade (5) positioned on a side where the other end (5Ab) of the base portion (5A) of the blade (5) is positioned and extending in the radial direction.
