摘要： A fan is disclosed that comprises an electronically commutated drive motor (27) and a bearing tube (62) which has an inner surface and an outer surface. The internal stator of the drive motor (27) is arranged in the area of the outer surface. An external rotor (28) of said motor cooperates with the internal stator (72) during operation. Blades (26) of the fan (22) are arranged on the outer circumference of the external rotor (28). Bearing elements (52, 54), by means of which a shaft (46) that is connected to the external rotor (28) is mounted, are disposed on the inner surface of the bearing tube (62). Ducts that are provided inside the bearing tube (62) allow coolant to flow through the bearing tube (62) during operation of the fan (22).

摘要： A fan comprises an impeller (120) that is provided with blades (26, 28, 30, 32, 34; 126). The blades are designed in such a way that the load on individual blades differs during operation of the fan. This variable load on the blades allows the frequencies associated with the blade passing frequency (BPF) of the fan to be spread across a wider frequency spectrum and thus be less disturbing.
摘要翻译：风扇具有设有叶片（26,28,30,32,34; 126）的叶轮（120）。刀片的设计使操作过程中单个刀片上的负载不同。由于这种可变的叶片负载，与风扇的旋转声音（BPF）相关的频率可以分布在更宽的频谱上，因此具有较小的干扰效应。
