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.
