Abstract: An electric motor-driven pump is configured to convey fluid. The pump includes a pump housing which has a suction region and an outlet region and delimits or forms a pump chamber. A hollow rotor axle, through which a rotor channel passes, and a pump impeller, which is mounted on the same in a rotationally adjustable manner, are arranged in the pump chamber for conveying fluid. The electric motor-driven pump has a cooling circuit that is open to the pump chamber and is designed to cool an electric drive motor arranged in a motor region of the pump housing to drive the pump impeller in rotation.

Abstract: A system includes at least one component package. Each of the component packages includes at least one electronic component such as a semiconductor component. Each component has a first outer surface and a second outer surface facing away from the first outer surface. Improved cooling efficiency and simplified manufacture are achieved by providing a cooler for at least one of the outer surfaces of the components. A flow path in the cooler substantially locally extends over the associated outer surface.
