Abstract (en)
[origin: WO2020225132A1] A cooling device for cooling an electrical machine, the electrical machine comprising wound stator coils having end portions and axial portions, the cooling device comprising an annular heat collector arranged for engaging with an external heat sink, a plurality of coil receiving spaces each delimited by at least two radial extensions extending radially from the annular heat collector, the plurality of coil receiving spaces being arranged for receiving end portions of the plurality of wound stator coils, wherein the cooling device is made from a thermally conductive and non-ferromagnetic material, such that in use heat generated by the plurality of wound stator coils is conducted in a radial direction along the plurality of radial extensions and along the annular heat collector towards the external heat sink.
