  • Electric charging device with fluid cooling
    Patent number: 10971974
    Abstract: A charging device for an internal combustion engine with a shaft, a compressor wheel arranged on the shaft, a stator housing and a stator. The stator is arranged within the stator housing. A rotor is arranged on the shaft and a cooling channel for accommodating a coolant extends axially between the stator housing and the stator. A split tube is provided between the rotor and stator. A first seal is provided in the axial direction between the stator housing and a first end of the stator and a second seal is provided in the axial direction between the stator housing and a first end of the split tube. Alternatively to the split tube, a separation tube is arranged between the stator and the stator housing so that the cooling channel is formed in the radial direction between the separation tube and the stator housing.
