Abstract
An electric machine for a vehicle may include a stator, a rotor, and a coolant channel assembly. The stator may include a core defining a cavity and windings disposed within and partially protruding out of the cavity. The rotor may be sized for disposal within the cavity adjacent the windings. The coolant channel assembly may include a channel wound about the partially protruding windings such that the channel and windings are in thermal communication with one another. The coolant channel may define a circular or rectangular cross-section. The coolant channel may define fins therein to induce turbulence into coolant flowing therethrough. The coolant channel and the windings may be arranged such that the coolant channel assembly directly contacts the windings. The coolant channel assembly may be wound such that a portion of the coolant channel assembly is partially disposed between the plurality of base portions.
