Abstract: A diecasting tool has an insert for producing a cooled motor housing. The diecasting tool has mould halves including: a stationary mould half; and movable mould half. One of the mould halves has a cylindrically extending annular gap having a central axis. The moveable mould half is arranged so as to be movable parallel to the central axis. The insert is arranged in the cylindrically extending annular gap. The insert is a bush. One end of the bush projects into a mould cavity, which is formed by the stationary mould half and the movable mould half, and is at least partially surrounded in a form-fitting manner by the casting material in a state when the casting material is cast.

Abstract: An electric motor housing with cooling includes: a housing, the housing having a round cross-section, an outer shell, a terminating wall and an inner shell, the housing being formed as a one-piece lightweight metal cast component. A cooling gap is formed between the outer shell and the inner shell and a spiral-shaped element is arranged in the cooling gap. The spiral-shaped element includes a spiral-shaped cooling channel which runs between the windings of the spiral-shaped element.

Abstract: An apparatus for utilizing waste heat of an internal combustion engine includes an exhaust gas manifold and a thermoelectric element. The thermoelectric element is configured to generate an electric voltage as a result of a temperature difference between a side facing away from the exhaust gas manifold and an opposite side. The thermoelectric element is arranged on the exhaust gas manifold. The apparatus additionally includes a cooling element arranged on the thermoelectric element on the side facing away from the exhaust gas manifold. The cooling element has at least one cooling passage configured to provide for the throughflow of a fluid.
