| 摘要 |
The invention relates to a fan device, comprising an electric motor assembly (24, 26), which is designed to drive at least one blade wheel (34, 36) in a flow channel (18) provided axial to the blade wheel, an electronic assembly (38, 40), which forms commutator and/or ballast electronics for the electric motor assembly, is arranged in series with the electric motor assembly, and is realized on a circuit carrier, and a carrier unit formed axially on or in the flow channel for retaining the electric motor assembly, wherein the carrier unit, which forms an inner circumference of the flow channel at least in some sections, is made of a thermally conductive material, wherein the carrier unit has, on an outer segment (16) radially opposite to the flow channel, a mounting and cooling surface for interacting with the circuit carrier and/or power electronics components provided thereon in a heat-dissipating manner. |
