Electrical circuit having circuit components to be cooled, heat sink, and method for sealingly embedding an electrical circuit

The invention relates to an electrical circuit having at least one circuit component to be cooled and at least one heat sink that is thermally conductively connected to the circuit component. The electrical circuit further comprises a plastic jacket in which the electrical circuit is embedded. The plastic jacket comprises an outer face and the heat sink engages a segment of the outer face. The electrical circuit comprises a sealing element that sealingly connects the heat sink to the plastic jacket, forming a frictional connection. The sealing element separates the environment of the electrical circuit from the at least one circuit component to be cooled within the interior of the plastic jacket in a fluid-tight manner. The invention further relates to a heat sink having a heat source contact surface and a heat sink contact segment connected to each other by means of a connecting segment. The connecting segment comprises an outer surface having structural features. The invention finally relates to a correspon
