摘要： An impeller wheel for fans has a bottom disc, a cover disc, and three-dimensionally shaped blades connected to the bottom disc and the cover disc. The bottom disc, cover disc, and the blades form a one-piece part. The blades have a leading edge and a trailing edge, wherein the leading edge and the trailing edge each have a median diameter. In a projection onto a cylinder that is coaxial with a rotation axis of the impeller wheel and has a diameter matching a median diameter of the trailing edge or of the leading edge, a first extension of the trailing edge and/or the leading edge is positioned at a first angle and a second extension of the trailing edge and/or the leading edge is positioned at a second angle relative to a line parallel to the rotation axis. At least one of the first and second angles is different from 0°.

摘要： The cooling device is intended for an electric motor and has a rotor cooling flange and a stator cooling flange (2), of which one is rotatable with respect to the other. At least one of the two cooling flanges (2) is provided with cooling ribs (8) arranged distributed over its circumference. During operation of the electric motor, at least one of the two cooling flanges gives off heat to the surrounding air. At least some of the cooling ribs (8) of a heat-emitting cooling flange (2) have an undulating profile over their length. In this context, the surface area of a cooling rib (8) having an undulating profile is larger than the surface area of the associated straight reference rib.

摘要： An axial fan has a housing and a motor with motor shaft and blower wheel attached to the motor shaft. The blower wheel has fan blades attached to a hub and provided with a leading and a trailing edge, respectively. A suspension arrangement is provided with a brace part made from flat material. The brace part connects motor and housing and has a length measured in a direction from motor to housing. The brace part is arranged on edge in an airflow direction and has a width measured in the airflow direction. The brace part has two limbs extending lengthwise in length direction of the brace part. The limbs are spaced apart from each other and delimit opposite sides of an opening formed by a punch-out in the flat material and extending along some of the length. The limbs are arranged one behind the other in airflow direction.

摘要： The invention relates to a fan wheel having blades (11) which are distributed over the circumference and are connected to one another in the circumferential direction via at least one ring. The fan wheel consists of at least three integrally formed segments (I to VII). Said segments comprise at least one respective ring portion (1) of at least one ring as well as either a blade (II) or at least a portion of the blades. The segments (I to VII) are joined together to form the fan wheel. The ring portions (1) lie against each other with edges (4, 5) which form the joining areas (15, 16) that are disposed transversely with respect to the circumferential direction of the fan wheel. At least one edge (4) of the ring portion (1) of each segment (I to VII) is provided with at least one projecting form-fitting part (18), and at least one edge (4, 5) of the ring portion (1) of each segment (I to VII) is provided with at least one recess (17) which is at least approximately complementary to the form-fitting part (18).

摘要： The axial fan has a motor (1), on the rotor side of which an impeller is fixed, wherein fan blades (24) with a front and a rear edge (26, 27) project from the hub of said impeller. The motor (1) is fixed to a housing (3) by means of a suspension (2). The suspension has a bracing part (4 to 8) made of a flat material, said bracing part connecting the motor (1) to the housing (3) and being arranged in an approximately vertical manner in the flow direction of the air. The aim of the invention is to design the axial fan such that the axial fan has a high overall efficiency and only a low flow resistance. This is achieved in that the bracing part (4 to 8) is provided with at least one recess (7) over a part of the length of the bracing part. The flow resistance due to the bracing part is minimized by means of the recess. The recess reduces the weight of the axial fan. The noise emitted by the axial fan is significantly reduced because the size of vortex-related flow separation regions is significantly reduced by means of the recess.
摘要翻译：轴流风扇具有电机（1），转子侧固定有叶轮，其中具有前边缘和后边缘（26,27）的风扇叶片（24）从所述叶轮的轮毂突出。电动机（1）通过悬架（2）固定到壳体（3）上。悬架具有由扁平材料制成的支撑部分（4至8），所述支撑部分将电动机（1）连接到壳体（3）并且沿空气的流动方向以大致垂直的方式布置。本发明的目的是设计轴流式风扇，使得轴流式风扇具有较高的整体效率和低流动阻力。这是通过支撑部分（4至8）在支撑部分的长度的一部分上设置有至少一个凹部（7）来实现的。由于支撑部分的流动阻力通过凹槽被最小化。该凹槽减小了轴流风扇的重量。由于通过凹槽显着地减小了涡流相关流动分离区域的尺寸，所以轴流式风扇发出的噪音显着降低。
