Abstract
An aircraft powerplant assembly includes a cooling plate and an electric machine controller. The cooling plate includes a fluid cooling circuit internal to a body of the cooling plate. The fluid cooling circuit includes an inlet manifold, an outlet manifold and a plurality of heat exchange passages. Each of the heat exchange passages extends longitudinally along a longitudinal centerline from the inlet manifold to the outlet manifold. A first heat exchange passage is configured with a plurality of first cooling elements arranged longitudinally along its longitudinal centerline. The electric machine controller includes a controller housing and controller circuitry. The controller housing is removably attached to the cooling plate and overlaps the heat exchange passages. The controller circuitry is disposed within an interior of the controller housing. The controller circuitry is in thermal communication with the cooling plate through a wall of the controller housing.
