Abstract: A workpiece set includes: a supporting structure; and a blank of a heat sink for fitting in place in the supporting structure. The supporting structure has an inner dimension for receiving the blank of the heat sink in a received state. The blank of the heat sink includes: a heat sink base for thermally contacting an electrical component on a printed circuit board, which is anchored or anchorable in the supporting structure, and a plurality of fins, which in the received state have an extent in a direction of the inner dimension, at least one first fin of the plurality of fins extending over a first dimension from the heat sink base in a first direction, and at least one second fin of the plurality of fins extending over a second dimension from the heat sink base in a second direction opposite the first direction.

Abstract: An assembly of an electrical device includes: at least one electrical functional assembly which has a supporting element and electrical or electronic functional components arranged on the supporting element; a fastening device for fastening the electrical device to a higher-level assembly; a heat sink core element having at least one face wall; and an external element connectable to the heat sink core element. The heat sink core element forms a supporting structure of the electrical device on which supporting structure the fastening device is arranged. The external element is connectable to the heat sink core element such that the at least one electrical functional assembly is accommodated between the at least one face wall of the heat sink core element and the external element.
