| 摘要 |
A fan arrangement (10) has a first axial fan (20), a second axial fan (40), and a guide apparatus (60). The first axial fan has: a first electric motor (21) having a first external rotor (22) and a first internal stator (23); a first fan wheel (24) connected to the first external rotor and having a first plurality of fan blades (25); a first base part (26) connected to the first internal stator; and a first fan housing (27) that at least partly surrounds the first electric motor. The second axial fan has: a similar structure. The first fan housing defines, together with the first fan wheel, an annular first conduit (32) through which a fluid is deliverable during operation by rotation of the first fan wheel around a first rotation axis (30) of the first external rotor. The second fan housing defines, together with the second fan wheel, an annular second conduit (52) through which the fluid is deliverable, during operation, by rotation of the second fan wheel around a second rotation axis (50) of the second external rotor. |

1. A fan arrangement comprising
a first axial fan (20), a second axial fan (40), and a guide apparatus (60),
the first axial fan (20) including: a first electric motor (21) having a first external rotor (22) and a first internal stator (23); a first fan wheel (24) connected to the first external rotor (22) and having a first plurality of fan blades (25); a first base part (26) connected to the first internal stator (23); and a first fan housing (27), which first fan housing (27) at least partly surrounds the first electric motor (21); and
the second axial fan (40) including: a second electric motor (41) having a second external rotor (42) and a second internal stator (43); a second fan wheel (44) connected to the second external rotor (42) and having a second plurality of fan blades (45); a second base part (46) connected to the second internal stator (43); and a second fan housing (47), which second fan housing (47) at least partly surrounds the second electric motor (41);the first fan housing (27) defining, together with the first fan wheel (24), an annular first conduit (32) through which a fluid is deliverable during operation by rotation of the first fan wheel (24) around a first rotation axis (30) of the first external rotor (22);
the second fan housing (47) defining, together with the second fan wheel (44), an annular second conduit (52) through which the fluid is deliverable during operation by rotation of the second fan wheel (44) around a second rotation axis (50) of the second external rotor (42); andthe guide apparatus (60) including a guide apparatus housing (61) and a guide apparatus inner part (63) connected to the guide apparatus housing (61) with the aid of webs (62), which guide apparatus housing (61) defines, together with the guide apparatus inner part (63), an annular third conduit (64) through which the fluid is deliverable;the first base part (26) being attached to a first portion (68) of the guide apparatus inner part (63) and the second base part (46) being attached to a second portion (69) of the guide apparatus inner part (63); andthe first axial fan (20), the second axial fan (40), and the guide apparatus (60) being connected to one another in such a way that the first annular conduit (32), the second annular conduit (52), and the third annular conduit (64) collectively form a flowthrough-capable air conduit (13) of the fan arrangement (10). |
